HEICO CORPORATION AND SUBSIDIARIES NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS–UNAUDITED

1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

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 nine months endedJuly 31, 2012 are not necessarily indicative of the results which may be expected for the entire fiscal year.

StockSplit

In March 2012, 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 25, 2012 in the form of a 25% stock dividend distributed to shareholders of record as of April 13, 2012. All applicable share and per share information has been adjusted retrospectively to give effect to the 5-for-4 stock split.

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 May 2011, the FASB issued ASU 2011-04, “Amendments to Achieve Common Fair Value Measurement and Disclosure Requirements in U.S. GAAP and IFRSs,” which amends current fair value measurement and disclosure guidance to converge with International Financial Reporting Standards and provides increased transparency around valuation inputs and investment

6

categorization. ASU 2011-04 also requires new disclosures about qualitative and quantitative information regarding the unobservable inputs used in a fair value measurement that is categorized within Level 3 of the fair value hierarchy. The Company adopted ASU 2011-04 in the second quarter of fiscal 2012, resulting in only expanded fair value disclosures and no impact on the Company’s results of operations, financial position or cash flows.

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 the complexity and cost of performing a quantitative test for impairment of goodwill 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. Early adoption is permitted. 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.

In July 2012, the FASB issued ASU 2012-02, “Testing Indefinite-Lived Intangible Assets for Impairment,” which is intended to reduce the complexity and cost of performing a quantitative test for impairment of indefinite-lived intangible assets by permitting an entity the option to perform a qualitative evaluation about the likelihood that an indefinite-lived intangible asset is impaired in order to determine whether it should calculate the fair value of the asset. 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 an indefinite-lived intangible asset is less than its carrying amount. ASU 2012-02 is effective for annual and interim impairment tests performed for fiscal years beginning after September 15, 2012, or in fiscal 2013 for HEICO’s annual impairment test. Early adoption is permitted. 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.

2. ACQUISITIONS

On November 22, 2011, the Company, through its HEICO Electronic Technologies Corp. (“HEICO Electronic”) subsidiary, acquired Switchcraft, Inc. (“Switchcraft”) through the purchase of all of the stock of Switchcraft’s parent company, Switchcraft Holdco, Inc., for approximately $143.2 million, net of cash acquired. The purchase price of this acquisition was paid in cash, principally using proceeds from the Company’s revolving credit facility. Switchcraft is a leading designer and manufacturer of high performance, high reliability and harsh environment electronic connectors and other interconnect products. This acquisition is consistent with HEICO’s practice of acquiring outstanding, niche designers and manufacturers of critical components in the aerospace and electronic industries and will further enable the Company to broaden its product offerings, technologies and customer base.

The following table summarizes the allocation of the purchase price of Switchcraft to the estimated fair values of the tangible and identifiable intangible assets acquired and liabilities assumed (in thousands).

Assets acquired:
Goodwill		$76,581
Identifiable intangible assets	72,500
Inventories	13,086
Property, plant and equipment	10,166
Accounts receivable	6,123
Other assets	1,570
Total assets acquired, excluding cash		$180,026
Liabilities assumed:
Deferred income taxes		$30,448
Accrued expenses	2,252
Income taxes payable	2,016
Accounts payable	1,889
Other liabilities	258
Total liabilities assumed		$36,863
Net assets acquired, excluding cash		$143,163

The allocation of the purchase price to the tangible and identifiable assets acquired and liabilities assumed is preliminary until the Company obtains final information regarding their fair values. The primary items that generated the goodwill recognized were the premiums paid by the Company for the future earnings potential of Switchcraft and the value of its assembled workforce that do not qualify for separate recognition. The operating results of Switchcraft were included in the Company’s results of operations from the effective acquisition date. The Company’s consolidated net sales and net income attributable to HEICO for the nine months ended July 31, 2012, includes approximately $40.1 million and $2.5 million, respectively, from the acquisition of Switchcraft. The Company’s consolidated net sales and net income

8

attributable to HEICO for the three months ended July 31, 2012, includes approximately $14.6 million and $1.0 million, respectively, from the acquisition of Switchcraft.

The following table presents unaudited pro forma financial information for the nine and three months ended July 31, 2011 as if the acquisition of Switchcraft had occurred as of November 1, 2010 (in thousands).

	Nine months ended		Three months ended
	July 31, 2011		July 31, 2011
Net sales		$600,593		$212,480
Net income from consolidated operations		$74,877		$27,944
Net income attributable to HEICO		$58,142		$21,954
Net income per share attributable to HEICO shareholders:
Basic		$1.12		$.42
Diluted		$1.09		$.41

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, 2010. The unaudited pro forma financial information includes adjustments to historical amounts such as additional amortization expense related to intangible assets acquired, increased interest expense associated with borrowings to finance the acquisition and inventory purchase accounting adjustments charged to cost of sales as the inventory is sold. Had the acquisition been consummated as of November 1, 2010, 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 the nine and three months ended July 31, 2012 would not have been materially different than the reported amounts.

In March 2012, the Company, through HEICO Electronic, acquired the business and substantially all of the assets of Ramona Research, Inc. (“Ramona Research”). Ramona Research designs and manufactures RF and microwave amplifiers, transmitters and receivers primarily used to support military communications on unmanned aerial systems, other aircraft, helicopters and ground-based data/communications systems. The purchase price of this acquisition was paid in cash principally using proceeds from the Company’s revolving credit facility. The total consideration includes an accrual of approximately $10.8 million representing the fair value of contingent consideration in aggregate that the Company may be obligated to pay should Ramona Research meet certain earnings objectives during each of the first five years following the acquisition. The maximum amount of contingent consideration that the Company could be required to pay is $14.6 million in aggregate. See Note 7, Fair Value Measurements, for additional information regarding the Company’s contingent consideration obligation.

In April 2012, the Company, through a subsidiary of HEICO Electronic, acquired certain aerospace assets of Moritz Aerospace, Inc. (“Moritz Aerospace”) in an aerospace product line

9

acquisition. The Moritz Aerospace product line designs and manufactures next generation wireless cabin control systems, solid state power distribution and management systems and fuel level sensing systems for business jets and for general aviation, as well as for the military/defense market segments. The purchase price of this acquisition was paid using cash provided by operating activities.

The total consideration and related allocation to the tangible and identifiable intangible assets acquired and liabilities assumed for the acquisitions of Ramona Research and Moritz Aerospace is not material or significant to the Company’s condensed consolidated financial statements. The operating results of Ramona Research and Moritz Aerospace were included in the Company’s results of operations from the effective acquisition dates. The amount of net sales and earnings of Ramona Research and Moritz Aerospace included in the Condensed Consolidated Statements of Operations is not material. Had the Ramona Research and Moritz Aerospace acquisitions been consummated as of November 1, 2010, 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 the nine and three months ended July 31, 2012 and 2011 would not have been materially different than the reported amounts.

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 the third quarter of fiscal 2012, the Company, through HEICO Electronic, paid $10.1 million of such additional purchase consideration using cash provided by operating activities. During the second and third quarters of fiscal 2011, the Company, through HEICO Electronic, paid $4.1 million and $1.3 million, respectively, of such additional purchase consideration using cash provided by operating activities. During the third quarter of fiscal 2011, HEICO Electronic accrued $1.2 million of additional purchase consideration related to a prior year acquisition for which the earnings objectives were met during fiscal 2011. The amount paid in fiscal 2012 and the amounts paid and accrued in fiscal 2011 were based on a multiple of the respective 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.

Accrued Customer Rebates and Credits

The aggregate amount of accrued customer rebates and credits included within accrued expenses and other current liabilities in the accompanying Condensed Consolidated Balance Sheets was $10.3 million and $9.6 million as of July 31, 2012 and October 31, 2011, respectively. The total customer rebates and credits deducted within net sales for the nine months endedJuly 31, 2012 and 2011 was $2.1 million and $6.7 million, respectively. The total customer rebates and credits deducted within net sales for the three months ended July 31, 2012 and 2011 was $1.0 million and $2.3 million, respectively. The decrease in customer rebates and credits principally reflects a reduction in the net sales volume of certain customers eligible for rebates as well as a reduction in associated rebate percentages.

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 by operating segment for the nine months ended July 31, 2012 are as follows (in thousands):

	Segment					Consolidated Totals
	FSG		ETG
Balances as of October 31, 2011		$192,357		$251,045			$443,402

Other	309		—			309
Balances as of July 31, 2012		$192,666		$338,928			$531,594

12

The goodwill acquired pertains to the current year acquisitions described in Note 2, Acquisitions, and represents the residual value after the allocation of the total consideration to the tangible and identifiable intangible assets acquired and liabilities assumed. The adjustments to goodwill during fiscal 2012 represent additional purchase price consideration paid relating to a prior year acquisition for which the earnings objectives were met in fiscal 2012. See Note 2, Acquisitions, for additional information regarding additional contingent purchase consideration. The Company estimates that approximately $13 million of the goodwill recognized in fiscal 2012 will be deductible for income tax purposes.

Identifiable intangible assets consist of the following (in thousands):

	As of July 31, 2012							As of October 31, 2011
	Gross Carrying Amount		Accumulated Amortization			Net Carrying Amount		Gross Carrying Amount		Accumulated Amortization			Net Carrying Amount
Amortizing Assets:
Customer relationships		$98,313		($22,318	)		$75,995		$51,934		($18,085	)		$33,849
Intellectual property	38,164		(4,656		)	33,508		18,493		(2,236		)	16,257
Licenses	2,900		(1,051		)	1,849		2,900		(854		)	2,046

Trade names	566		(308		)	258		569		(224		)	345
	141,906		(29,973		)	111,933		75,836		(22,915		)	52,921
Non-Amortizing Assets:
Trade names	35,277		—			35,277		25,236		—			25,236
		$177,183		($29,973	)		$147,210		$101,072		($22,915	)		$78,157

The increase in the gross carrying amount of customer relationships, intellectual property and non-amortizing trade names as of July 31, 2012 compared to October 31, 2011 principally relates to such intangible assets recognized in connection with acquisitions made during fiscal 2012 (see Note 2, Acquisitions). The weighted average amortization period of the customer relationships and intellectual property acquired is 10 years and 11 years, respectively.

Amortization expense related to intangible assets for the nine months endedJuly 31, 2012 and 2011 was $11.7 million and $5.4 million, respectively. Amortization expense related to intangible assets for the three months endedJuly 31, 2012 and 2011 was $4.2 million and $1.9 million, respectively. Amortization expense related to intangible assets for the remainder of fiscal 2012 is estimated to be $4.2 million. Amortization expense for each of the next five fiscal years and thereafter is estimated to be $16.1 million in fiscal 2013, $15.5 million in fiscal 2014, $14.0 million in fiscal 2015, $12.6 million in fiscal 2016, $12.0 million in fiscal 2017 and $37.5 million thereafter.

5. LONG-TERM DEBT

Long-term debt consists of the following (in thousands):

	July 31, 2012			October 31, 2011
Borrowings under revolving credit facility		$149,000			$36,000
Capital lease and notes payable	3,919			4,158
	152,919			40,158
Less: Current maturities of long-term debt	(304		)	(335		)
		$152,615			$39,823

On December 14, 2011, the Company entered into a $670 million Revolving Credit Agreement (“New Credit Facility”) with a bank syndicate, which matures in December 2016. Under certain circumstances, the maturity of the New Credit Facility may be extended for two one-year periods. The New Credit Facility also includes a feature that will allow the Company to increase the New Credit Facility by $130 million, at its option, to become an $800 million facility through increased commitments from existing lenders or the addition of new lenders. The New Credit Facility may be used for working capital and general corporate needs of the Company, including capital expenditures and to finance acquisitions. The New Credit Facility replaced the $300 million Second Amended and Restated Revolving Credit Facility Agreement.

Advances under the New 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 interests and non-cash charges, or “leverage ratio”). The Base Rate is the highest of (i) the Prime Rate; (ii) the Federal Funds rate plus .50% per annum; and (iii) the Adjusted LIBO Rate determined on a daily basis for an Interest Period of one month plus 1.00% per annum, as such capitalized terms are defined in the New Credit Facility. The applicable margins for LIBOR-based borrowings range from .75% to 2.25%. The applicable margins for Base Rate borrowings range from 0% to 1.25%. A fee is charged on the amount of the unused commitment ranging from .125% to .35% (depending on the Company’s leverage ratio). The New Credit Facility also includes a $50 million sublimit for borrowings made in foreign currencies, letters of credit and swingline borrowings. Outstanding principal, accrued and unpaid interest and other amounts payable under the New Credit Facility may be accelerated upon an event of default, as such events are described in the New Credit Facility. The New Credit Facility is unsecured and contains covenants that require, among other things, the maintenance of a total 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 New Credit Facility would become secured by the capital stock owned in substantially all of the Company’s subsidiaries.

As of July 31, 2012 and October 31, 2011, the weighted average interest rate on borrowings under the Company’s revolving credit facility was 1.3% and .9%, respectively. The revolving credit facility contains both financial and non-financial covenants. As of July 31, 2012, the Company was in compliance with all such covenants.

6. INCOME TAXES

As of July 31, 2012, the Company’s liability for gross unrecognized tax benefits related to uncertain tax positions was $1.8 million of which $1.2 million 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 for the nine months endedJuly 31, 2012 is as follows (in thousands):

Balance as of October 31, 2011		$1,834
Increases related to prior year tax positions	552
Decreases related to prior year tax positions	(240		)
Increases related to current year tax positions	216
Settlements	(52		)
Lapse of statutes of limitations	(485		)
Balance as of July 31, 2012		$1,825

There were no material changes in the liability for unrecognized tax positions resulting from tax positions taken during the current or a prior year, settlements with other taxing authorities or a lapse of applicable statutes of limitations. The accrual of interest and penalties related to the unrecognized tax benefits was not material for the nine months endedJuly 31, 2012. Further, the Company does not expect the total amount of unrecognized tax benefits to materially change in the next twelve months.    

During the third quarter of fiscal 2012, the Company filed its fiscal 2011 U.S. federal and state tax returns and recognized an aggregate benefit, which increased net income attributable to HEICO by $.9 million, from higher fiscal 2011 research and development tax credits. The higher research and development tax credits reflect the finalization of a study of qualifying fiscal 2011 research and development activities and a reduction in the liability for gross unrecognized research and development related tax positions due to a lapse of the statute of limitations.

During the third quarter of fiscal 2011, the Company filed its fiscal 2010 U.S. federal and state tax returns and amended certain prior year state tax returns and recognized an aggregate benefit, which increased net income attributable to HEICO by $2.0 million, principally from state income apportionment updates ($.9 million) and higher research and development tax credits ($.9 million).

The Company's effective tax rate in the first nine months of fiscal 2012 increased to 33.3% from 29.7% in the first nine months of fiscal 2011. The effective tax rate for the first nine months of fiscal 2011 reflects the aforementioned benefit from state income apportionment updates recognized upon the filing of the Company’s fiscal 2010 state tax returns and the amendment of certain prior year state tax returns in the third quarter of fiscal 2011. The increase in the effective tax rate in fiscal 2012 is also due to the retroactive extension of Section 41 of the Internal Revenue Code, “Credit for Increasing Research Activities,” to cover the period from January 1, 2010 to December 31, 2011, which resulted in the recognition of an income tax credit for qualified research and development activities for the last ten months of fiscal 2010 in the first

15

quarter of fiscal 2011 and reduced the recognition of such income tax credit to just the first two months of qualifying research and development activities in fiscal 2012. In addition, the increase reflects a higher effective state income tax rate attributable to a fiscal 2012 acquisition and changes in certain state tax laws which impacted state apportionment factors. During fiscal 2011 and 2012, the Company purchased certain noncontrolling interests that also contributed to the comparative increase in the effective tax rate for the first nine months of fiscal 2012.

7. FAIR VALUE MEASUREMENTS

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 (in thousands):

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 and are valued using a market approach. Certain other assets of the LCP represent investments in money market funds that are classified within Level 1. The majority of the assets of the Company’s other deferred compensation plan are principally invested in equity securities, mutual funds and money market funds that are classified within Level 1. A portion of the assets within the other deferred compensation plan is currently invested in a fund that invests in future and forward contracts, most of which are privately negotiated with counterparties without going through a public exchange and that use trading methods that are proprietary and confidential. These assets are therefore classified within Level 3 and are valued using a market approach with corresponding gains and losses reported within other income in the Company’s Condensed Consolidated Statements of Operations. The assets of both plans are held within irrevocable trusts and classified within other assets in the Company’s Condensed Consolidated Balance Sheets and have an aggregate value of $39.5 million as of July 31, 2012 and $31.1 million as of October 31, 2011, of which the LCP related assets were $35.3 million and $27.0 million as of July 31, 2012 and October 31, 2011, respectively. The related liabilities of the two deferred compensation plans are included within other long-term liabilities in the Company’s Condensed Consolidated Balance Sheets and have an aggregate value of $39.0 million as of July 31, 2012 and $30.8 million as of October 31, 2011, of which the LCP related liability was $34.8 million and $26.7 million as of July 31, 2012 and October 31, 2011, respectively.

As part of the agreement to acquire a subsidiary by the ETG in the second quarter of fiscal 2012, the Company may be obligated to pay contingent consideration of up to $14.6 million in aggregate should the acquired entity meet certain earnings objectives during each of the first five years following the acquisition. The $10.8 million estimated fair value of the contingent consideration as of the acquisition date is classified within Level 3 and was determined using a probability-based scenario analysis approach. Under this method, a set of discrete potential future subsidiary earnings was determined using internal estimates based on various revenue growth rate assumptions for each scenario that ranged from a compound annual growth rate of (8%) to 20%. A probability of likelihood was assigned to each discrete potential future earnings estimate and the resultant contingent consideration was calculated. The resulting probability-weighted contingent consideration amounts were discounted using a weighted average discount rate of 3.5% reflecting the credit risk of a market participant. Significant changes to either the revenue growth rates, related earnings or the discount rate could result in a material change to the amount of contingent consideration accrued and such changes will be recorded in the Company’s condensed consolidated statements of operations. Changes in the fair value of this contingent consideration were not material during the period ended July 31, 2012. As of July 31, 2012, the estimated amount of such contingent consideration to be paid within the next twelve months of $1.6 million is included in accrued expenses and other current liabilities and the remaining $9.3 million is included in other long-term liabilities in the Company’s Condensed Consolidated Balance Sheet.

Changes in the Company’s assets and liabilities measured at fair value on a recurring

17

basis using unobservable inputs (Level 3) for the nine months endedJuly 31, 2012 are as follows (in thousands):

	Assets		Liabilities
Balances as of October 31, 2011		$573		$—
Contingent consideration related to acquisition	—		10,778
Increase in value of contingent consideration	—		143
Total unrealized gains	4		—
Balances as of July 31, 2012		$577		$10,921

The Company did not have any transfers between Level 1 and Level 2 fair value measurements during the nine months ended July 31, 2012.

The carrying amounts of the Company’s cash and cash equivalents, accounts receivable, trade accounts payable and accrued expenses and other current liabilities approximate fair value as of July 31, 2012 due to the relatively short maturity of the respective instruments. The carrying amount of long-term debt approximates fair value due to its variable interest rates.

8. RESEARCH AND DEVELOPMENT EXPENSES

Cost of sales for the nine months endedJuly 31, 2012 and 2011 includes approximately $22.4 million and $18.2 million, respectively, of new product research and development expenses. Cost of sales for the three months ended July 31, 2012 and 2011 includes approximately $7.5 million and $6.5 million, respectively, of new product research and development expenses.

9. 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 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 July 31, 2012, management’s estimate of the aggregate Redemption Amount of all Put Rights that the Company would be required to pay is approximately $59 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, 2012 redeemable at fair value is approximately $34 million and the portion redeemable based solely on a multiple of future earnings is approximately $25 million. Adjustments to Redemption Amounts based on fair value will have no affect on net income per share attributable to HEICO shareholders

18

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 February 2012, the Company, through its HEICO Aerospace Holdings Corp. (“HEICO Aerospace”) subsidiary, acquired an additional 6.7% equity interest in one of its subsidiaries, which increased the Company’s ownership interest to 86.7%. The purchase price of the redeemable noncontrolling interests acquired was paid using cash provided by operating activities.

10. NET INCOME PER SHARE ATTRIBUTABLE TO HEICO SHAREHOLDERS

The computation of basic and diluted net income per share attributable to HEICO shareholders is as follows (in thousands, except per share data):

	Nine months ended July 31,				Three months ended July 31,
	2012		2011		2012		2011
Numerator:
Net income attributable to HEICO		$61,356		$54,306		$23,128		$20,402
Denominator:
Weighted average common shares outstanding-basic	52,651		51,965		52,695		52,161
Effect of dilutive stock options	639		1,134		593		1,051
Weighted average common shares outstanding-diluted	53,290		53,099		53,288		53,212
Net income per share attributable to HEICO shareholders:
Basic		$1.17		$1.05		$.44		$.39
Diluted		$1.15		$1.02		$.43		$.38
Anti-dilutive stock options excluded	667		444		720		341

No portion of the adjustments to the redemption amount of redeemable noncontrolling interests of ($.1) million and ($1.6) million for the nine months endedJuly 31, 2012 and 2011, respectively, and ($.6) million and ($1.0) million for the three months ended July 31, 2012 and 2011, respectively, reflect a redemption amount in excess of fair value and therefore no portion of the adjustments affect basic or diluted net income per share attributable to HEICO shareholders.

As part of the agreement to acquire a subsidiary by the ETG in fiscal 2007, the Company may have been obligated to pay additional purchase consideration of up to 73 million Canadian dollars in aggregate, which translates to approximately $71 million U.S. dollars based on the June 30, 2012 exchange rate, had the subsidiary met certain earnings objectives through June 2012. Based on the subsidiary’s actual earnings through the measurement period, no additional purchase consideration will be paid.

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.

13. SUBSEQUENT EVENT

In August 2012, the Company, through its HEICO Flight Support Corp. subsidiary, acquired 84% of the assets and assumed certain liabilities of CSI Aerospace, Inc. (“CSI Aerospace”). CSI Aerospace is a leading repair and overhaul provider of specialized components for airlines, military and other aerospace related organizations. The remaining 16% interest continues to be owned by certain members of CSI Aerospace’s management team. The purchase price was paid in cash principally using proceeds from the Company’s revolving credit facility. The total consideration for this acquisition and related allocation to the tangible and identifiable intangible assets acquired and liabilities assumed is not material or significant to the Company’s condensed consolidated financial statements.

Item 2. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

Overview

This discussion of our financial condition and results of operations should be read in conjunction with our condensed consolidated financial statements and notes thereto included herein. The preparation of consolidated 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 consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ materially from those estimates if different assumptions were used or different events ultimately transpire.

Our critical accounting policies, which require management to make judgments about matters that are inherently uncertain, are described in Item 7, “Management’s Discussion and Analysis of Financial Condition and Results of Operations,” under the heading “Critical Accounting Policies” in our Annual Report on Form 10-K for the year ended October 31, 2011. There have been no material changes to our critical accounting policies during the nine months ended July 31, 2012.

Our business is comprised of two operating segments: the Flight Support Group (“FSG”), consisting of HEICO Aerospace Holdings Corp. (“HEICO Aerospace”) and its subsidiaries, and the Electronic Technologies Group (“ETG”), consisting of HEICO Electronic Technologies Corp. (“HEICO Electronic”) and its subsidiaries.

Our results of operations for the nine and three months ended July 31, 2012 have been affected by the fiscal 2012 acquisitions as further detailed in Note 2, Acquisitions, of the Notes to Condensed Consolidated Financial Statements of this quarterly report and by the fiscal 2011 acquisitions as further detailed in Note 2, Acquisitions, of the Notes to Consolidated Financial Statements of our Annual Report on Form 10-K for the year ended October 31, 2011.

All per share information has been adjusted retrospectively to reflect a 5-for-4 stock split effected in April 2012. See Note 1, Summary of Significant Accounting Policies – Stock Split, of the Notes to Condensed Consolidated Financial Statements for additional information regarding this stock split.

Comparison of First Nine Months of Fiscal 2012 to First Nine Months of Fiscal 2011

Net Sales

Our net sales for the first nine months of fiscal 2012increased by 18% to a record $654.9 million, as compared to net sales of $556.0 million for the first nine months of fiscal 2011. The increase in net sales reflects an increase of $74.7 million (a 46% increase) to a record $237.2 million in net sales within the ETG as well as an increase of $25.5 million (a 6% increase) to a record $420.7 million in net sales within the FSG. The net sales increase in the ETG reflects additional net sales of approximately $65.7 million from acquisitions of 3D Plus SA (“3D Plus”) in September 2011, Switchcraft, Inc. (“Switchcraft”) in November 2011, Ramona Research, Inc. (“Ramona Research”) in March 2012 and Moritz Aerospace, Inc. (“Moritz Aerospace”) in April 2012, as well as organic growth of approximately 5.6%. The organic growth in the ETG principally reflects an increase in demand and market penetration for certain defense, medical, aerospace and electronic products, resulting in a $4.2 million, $1.7 million, $1.6 million and $1.6 million increase in net sales from these product lines, respectively. Based on our current economic visibility, we continue to expect stable demand for ETG’s products for the remainder of fiscal 2012. The net sales increase in the FSG reflects organic growth of approximately 4.8%, as well as approximately $6.4 million in additional net sales contributed from an acquisition in December 2010. The organic growth in the FSG principally reflects an increase of $14.9 million in net sales within our specialty product lines primarily attributed to the sales of industrial products used in heavy-duty and off-road vehicles as a result of increased market penetration. Based on our current economic visibility, we expect growth within our specialty product lines to stabilize for the remainder of fiscal 2012. Additionally, the FSG’s organic growth reflects increased market penetration from both new and existing product offerings for certain of the FSG’s aerospace products resulting in an increase of $3.9 million within the FSG’s aftermarket replacement parts product lines. Based on our current economic visibility, we expect continued growth within our aftermarket replacement parts product lines for the remainder of fiscal 2012. Sales price changes were not a significant contributing factor to the ETG and FSG net sales growth in the first nine months of fiscal 2012.

Gross Profit and Operating Expenses

Our consolidated gross profit margin improved to 36.3% for the first nine months of fiscal 2012 as compared to 36.0% for the first nine months of fiscal 2011, principally reflecting a .9% increase in the FSG’s gross profit margin, partially offset by a 3.7% decrease in the ETG’s gross profit margin. The increase in the FSG’s gross profit margin is primarily attributed to the previously mentioned increased sales of higher gross profit margin products within our specialty product and aftermarket replacement parts product lines. The decrease in the ETG’s gross profit margin principally reflects a 2.0% impact from lower gross profit margins realized by Switchcraft and 3D Plus in the first nine months of fiscal 2012. The lower gross profit margins realized by these acquired businesses are principally attributed to amortization expense of certain acquired intangible assets of approximately $1.7 million and inventory purchase accounting adjustments of approximately $1.7 million. Additionally, the decrease in the ETG’s gross profit margin reflects a lower margin product mix of certain of our defense, space and medical products

24

in the first nine months of fiscal 2012. Total new product research and development expenses included within our consolidated cost of sales increased from approximately $18.2 million in the first nine months of fiscal 2011 to approximately $22.4 million in the first nine months of fiscal 2012, principally to further enhance growth opportunities and market penetration.

Selling, general and administrative (“SG&A”) expenses were $120.0 million and $99.1 million for the first nine months of fiscal 2012 and fiscal 2011, respectively. The increase in SG&A expenses reflects an increase of $13.4 million in general and administrative expenses and $7.5 million in selling expenses, of which $11.6 million in general and administrative expenses and $5.8 million in selling expenses were attributed to the acquired businesses. SG&A expenses as a percentage of net sales increased from 17.8% in the first nine months of fiscal 2011 to 18.3% in the first nine months of fiscal 2012 principally reflecting an increase in amortization expense of intangible assets from the acquired businesses.    

Operating Income

Operating income for the first nine months of fiscal 2012 increased by 17% to a record $117.7 million as compared to operating income of $101.0 million for the first nine months of fiscal 2011. The increase in operating income reflects a $10.1 million increase (a 15% increase) to a record $78.5 million in operating income of the FSG for the first nine months of fiscal 2012, up from $68.4 million in the first nine months of fiscal 2011 and a $7.9 million increase (an 18% increase) in operating income of the ETG to a record $52.5 million for the first nine months of fiscal 2012, up from $44.6 million for the first nine months of fiscal 2011. The increase in operating income of the FSG principally reflects the previously mentioned increased sales volumes and improved gross profit margin. The increase in the operating income of the ETG is mainly attributed to $8.7 million in operating income contributed by the acquired businesses and the organic sales growth partially offset by the previously mentioned lower gross profit margin.

As a percentage of net sales, our consolidated operating income decreased to 18.0% for the first nine months of fiscal 2012, down from 18.2% for the first nine months of fiscal 2011. The decrease in consolidated operating income as a percentage of net sales reflects a decrease in the ETG’s operating income as a percentage of net sales from 27.4% in the first nine months of fiscal 2011 to 22.1% in the first nine months of fiscal 2012, partially offset by an increase in the FSG’s operating income as a percentage of net sales from 17.3% in the first nine months of fiscal 2011 to 18.7% in the first nine months of fiscal 2012. The decrease in operating income as a percentage of net sales for the ETG principally reflects a 4.1% impact from lower operating margins realized by 3D Plus and Switchcraft as well as the previously mentioned lower gross profit margin. The lower operating margin realized by 3D Plus is principally attributed to amortization expense of approximately $2.9 million associated with intangible assets and inventory purchase accounting adjustments during the first nine months of fiscal 2012. Additionally, the lower operating margin realized by 3D Plus during the first nine months of fiscal 2012 reflects lower net sales for certain of its products during the first six months of fiscal 2012 resulting from the economic uncertainty throughout Europe. The lower operating margin realized by Switchcraft is principally attributed to amortization expense of approximately $5.4 million associated with intangible assets and inventory purchase accounting adjustments. Based

25

on variations in product mix and the timing of customer delivery requirements, the operating margin of the ETG can vary from quarter to quarter. Excluding 3D Plus and Switchcraft, the ETG’s operating margins for the first nine months of fiscal 2012 would have been approximately 26%, which is comparable to the ETG’s full year operating margins, which normally approximate 25%. The increase in operating income as a percentage of net sales for the FSG principally reflects the previously mentioned higher gross profit margins.

Interest Expense

Interest expense increased to $1.8 million in the first nine months of fiscal 2012 from $.1 million in the first nine months of fiscal 2011. The increase was principally due to a higher weighted average balance outstanding under our revolving credit facility in the first nine months of fiscal 2012 associated with the recent acquisitions.

Other Income

Other income in the first nine months of fiscal 2012 and 2011 was not material.

Income Tax Expense

Our effective tax rate in the first nine months of fiscal 2012 increased to 33.3% from 29.7% in the first nine months of fiscal 2011. The effective tax rate for the first nine months of fiscal 2011 reflects a benefit, which increased net income attributable to HEICO by $.9 million, net of expenses, from state income apportionment updates recognized upon the filing of our fiscal 2010 state tax returns and the amendment of certain prior year state tax returns in the third quarter of fiscal 2011. The increase in the effective tax rate in the first nine months of fiscal 2012 is also due to the retroactive extension of Section 41 of the Internal Revenue Code, “Credit for Increasing Research Activities,” to cover the period from January 1, 2010 to December 31, 2011, which resulted in the recognition of an income tax credit for qualified research and development activities for the last ten months of fiscal 2010 in the first quarter of fiscal 2011 and reduced the recognition of such income tax credit to just the first two months of qualifying research and development activities in fiscal 2012. In addition, the increase reflects a higher effective state income tax rate attributable to a fiscal 2012 acquisition and changes in certain state tax laws which impacted state apportionment factors. During fiscal 2011 and 2012, we purchased certain noncontrolling interests that also contributed to the comparative increase in the effective tax rate for the first nine months of fiscal 2012.

Net Income Attributable to Noncontrolling Interests

Net income attributable to noncontrolling interests relates to the 20% noncontrolling interest held in the FSG and the noncontrolling interests held in certain subsidiaries of the FSG and ETG. Net income attributable to noncontrolling interests was $16.0 million for the first nine months of fiscal 2012 compared to $16.7 million in the first nine months of fiscal 2011. The decrease in the first nine months of fiscal 2012 principally reflects our purchases of certain noncontrolling interests during fiscal 2011 and 2012 resulting in lower allocations of net income to noncontrolling interests. Additionally, the decrease is attributed to lower earnings of certain

26

ETG subsidiaries partially offset by higher earnings of the FSG in which the 20% noncontrolling interest is held.

Net Income Attributable to HEICO

Net income attributable to HEICO increased to a record $61.4 million, or $1.15 per diluted share, for the first nine months of fiscal 2012 from $54.3 million, or $1.02 per diluted share, for the first nine months of fiscal 2011, principally reflecting the increased operating income referenced above.

Comparison of Third Quarter of Fiscal 2012 to Third Quarter of Fiscal 2011

Net Sales

Our net sales for the third quarter of fiscal 2012 increased by 15% to a record $226.0 million, as compared to net sales of $197.3 million for the third quarter of fiscal 2011. The increase in net sales principally reflects an increase of $29.3 million (a 51% increase) to a record $86.5 million in net sales within the ETG. The net sales increase in the ETG reflects additional net sales of approximately $26.3 million from the acquisitions of 3D Plus, Switchcraft, Ramona Research and Moritz Aerospace, as well as organic growth of approximately 5.3%. The organic growth in the ETG principally reflects increased market penetration and demand for certain medical, electronic and aerospace products resulting in a $1.2 million, $1.1 million and $.7 million increase in net sales from these product lines. Net sales of the FSG were $140.8 million for the third quarter of fiscal 2012 compared to $140.7 million for the third quarter of fiscal 2011. The slight increase in FSG net sales reflects a $1.2 million increase within our specialty product lines primarily attributed to increased demand for certain of our aerospace and industrial products and a $1.1 million increase within the FSG’s aftermarket replacement parts product lines principally from increased market penetration from both new and existing product offerings partially offset by a slowing of aftermarket growth. The aforementioned increases in FSG net sales were partially offset by a $2.3 million decrease within the FSG’s repair and overhaul services principally reflecting a general slowing of airline capacity growth. Based on current economic visibility, we expect nominal net sales growth within our repair and overhaul services for the remainder of fiscal 2012. Sales price changes were not a significant contributing factor to the ETG and FSG net sales growth in the third quarter of fiscal 2012.

Gross Profit and Operating Expenses

Our consolidated gross profit margin improved to 37.3% for the third quarter of fiscal 2012 as compared to 35.4% for the third quarter of fiscal 2011, principally reflecting a 1.2% increase in the FSG’s gross profit margin, partially offset by a .5% decrease in the ETG’s gross profit margin. The increase in the FSG’s gross profit margin is primarily attributed to the previously mentioned increased sales of higher gross profit margin products within our aftermarket replacement parts and specialty products product lines. The decrease in the ETG’s gross profit margin principally reflects the impact of a somewhat lower gross profit margin realized by Switchcraft in the third quarter of fiscal 2012. Total new product research and development expenses included within our consolidated cost of sales increased from

27

approximately $6.5 million in the third quarter of fiscal 2011 to approximately $7.5 million in the third quarter of fiscal 2012, principally to further enhance growth opportunities and market penetration.

Selling, general and administrative (“SG&A”) expenses were $41.8 million and $34.1 million for the third quarter of fiscal 2012 and fiscal 2011, respectively. The increase in SG&A expenses reflects an increase of $4.8 million in general and administrative expenses and $2.9 million in selling expenses, of which $4.3 million in general and administrative expenses and $1.9 million in selling expenses were attributed to the acquired businesses. SG&A expenses as a percentage of net sales increased from 17.3% in the third quarter of fiscal 2011 to 18.5% in the third quarter of fiscal 2012 principally reflecting an increase in amortization expense of intangible assets from the acquired businesses and certain selling expenses within the ETG.

Operating Income

Operating income for the third quarter of fiscal 2012 increased by 19% to a record $42.5 million as compared to operating income of $35.7 million for the third quarter of fiscal 2011. The increase in operating income reflects a $5.6 million increase (a 36% increase) to a record $21.0 million in operating income of the ETG in the third quarter of fiscal 2012, up from $15.4 million in the third quarter of fiscal 2011 and a $1.8 million increase (a 7% increase) to $26.4 million in operating income of the FSG in the third quarter of fiscal 2012, up from $24.6 million in the third quarter of fiscal 2011. The increase in operating income of the FSG principally reflects the previously mentioned higher gross profit margin. The increase in the operating income of the ETG is mainly attributed to $5.1 million in operating income contributed by the acquired businesses and the organic sales growth.

As a percentage of net sales, our consolidated operating income increased to 18.8% for the third quarter of fiscal 2012, up from 18.1% for the third quarter of fiscal 2011. The increase in consolidated operating income as a percentage of net sales reflects an increase in the FSG’s operating income as a percentage of net sales from 17.4% in the third quarter of fiscal 2011 to 18.7% in the third quarter of fiscal 2012, partially offset by a decrease in the ETG’s operating income as a percentage of net sales from 26.9% in the third quarter of fiscal 2011 to 24.2% in the third quarter of fiscal 2012. The increase in operating income as a percentage of net sales for the FSG principally reflects the previously mentioned higher gross profit margins. The decrease in operating income as a percentage of net sales for the ETG principally reflects a 2.8% impact from a lower operating margin realized by Switchcraft and 3D Plus. The lower operating margin realized by Switchcraft and 3D Plus is principally attributed to amortization expense of approximately $1.6 million and $.7 million, respectively, associated with intangible assets. Based on variations in product mix and the timing of customer delivery requirements, the operating margin of the ETG can vary from quarter to quarter. Excluding Switchcraft and 3D Plus, the ETG’s operating margins for the third quarter of fiscal 2012 would have been approximately 27%, which is comparable to the ETG’s full year operating margins, which normally approximate 25%.

28

Interest Expense

Interest expense increased $.5 million in the third quarter of fiscal 2012. The increase was principally due to a higher weighted average balance outstanding under our revolving credit facility in the third quarter of fiscal 2012 associated with the recent acquisitions.

Other Income and Expense

Other income and expense in the third quarter of fiscal 2012 and 2011 was not material.

Income Tax Expense

Our effective tax rate in the third quarter of fiscal 2012 increased to 31.4% from 26.0% in the third quarter of fiscal 2011. The effective tax rate for the third quarter of fiscal 2011 reflects a benefit, which increased net income attributable to HEICO by $.9 million, net of expenses, from state income apportionment updates recognized upon the filing of our fiscal 2010 state tax returns and the amendment of certain prior year state tax returns. The increase in the effective tax rate in the third quarter of fiscal 2012 is also due to the expiration of Section 41 of the Internal Revenue Code, “Credit for Increasing Research Activities,” as of December 31, 2011, which reduced the amount of research and development tax credits recognized during the quarter. In addition, the increase reflects a higher effective state income tax rate attributable to a fiscal 2012 acquisition and changes in certain state tax laws which impacted state apportionment factors. During fiscal 2011 and 2012, we purchased certain noncontrolling interests that also contributed to the comparative increase in the effective tax rate for the third quarter of fiscal 2012.

Net Income Attributable to Noncontrolling Interests

Net income attributable to noncontrolling interests relates to the 20% noncontrolling interest held in the FSG and the noncontrolling interests held in certain subsidiaries of the FSG and ETG. Net income attributable to noncontrolling interests was $5.5 million in the third quarter of fiscal 2012 compared to $6.0 million in the third quarter of fiscal 2011. The decrease in the third quarter of fiscal 2012 principally reflects our purchases of certain noncontrolling interests during fiscal 2011 and 2012 resulting in lower allocations of net income to noncontrolling interests.

Net Income Attributable to HEICO

Net income attributable to HEICO increased to a record $23.1 million, or $.43 per diluted share, for the third quarter of fiscal 2012 from $20.4 million, or $.38 per diluted share, for the third quarter of fiscal 2011, principally reflecting the increased operating income referenced above.

Outlook

In our Flight Support Group’s markets, forecasts of potential decelerating capacity growth within the commercial aviation market and continued global economic uncertainty may

29

moderate our net sales growth for the remainder of fiscal 2012. In our Electronic Technologies Group’s markets, we generally anticipate stable demand for most of our products, but acknowledge that government deficits and spending reduction plans may moderate demand for certain of our defense products.

Liquidity and Capital Resources

Our principal uses of cash include acquisitions, capital expenditures, distributions to noncontrolling interests, cash dividends and increases in working capital needs. Capital expenditures in fiscal 2012 are anticipated to approximate $18 - $20 million.

We finance our activities primarily from our operating activities and financing activities, including borrowings under our revolving credit facility. The revolving credit facility contains both financial and non-financial covenants. As of July 31, 2012, we were in compliance with all such covenants. As of July 31, 2012, our net debt to shareholders’ equity ratio was 20.1%, with net debt (total debt less cash and cash equivalents) of $139.0 million.

Based on our current outlook, we believe that our net cash provided by operating activities and available borrowings under our revolving credit facility will be sufficient to fund cash requirements for at least the next twelve months.

Operating Activities

Net cash provided by operating activities was $78.3 million for the first nine months of fiscal 2012 and consisted primarily of net income from consolidated operations of $77.4 million. Net cash provided by operating activities decreased by $6.7 million from $85.0 million in the first nine months of fiscal 2011. The decrease in net cash provided by operating activities is principally due to a $21.3 million increase in working capital primarily from the timing of certain payments pertaining to fiscal 2011 year-end and the first nine months of fiscal 2012 accruals and payables and a build in inventory levels to meet customer demand, partially offset by increases in depreciation and amortization of $8.7 million and net income from consolidated operations of $6.3 million.

Investing Activities

Net cash used in investing activities of $184.0 million during the first nine months of fiscal 2012 related primarily to acquisitions of $171.5 million and capital expenditures totaling $12.4 million. Further details regarding the acquisitions made by the ETG in the first nine months of fiscal 2012 may be found in Note 2, Acquisitions, of the Notes to Condensed Consolidated Financial Statements.

Financing Activities

Net cash provided by financing activities during the first nine months of fiscal 2012 of $102.7 million related primarily to net borrowings on our revolving credit facility of $113.0 million and the presentation of $12.1 million of excess tax benefit from stock option exercises as a financing activity, partially offset by acquisitions of noncontrolling interests of $7.6 million,

30

distributions to noncontrolling interests of $6.8 million, the payment of $5.7 million in cash dividends on our common stock and issuance costs associated with our new revolving credit facility of $3.0 million.

Contractual Obligations

Except as otherwise noted below, there have not been any material changes to the amounts presented in the table of contractual obligations that was included in our Annual Report on Form 10-K for the year ended October 31, 2011.

As of July 31, 2012, we had a total of $149 million of outstanding borrowings under our revolving credit facility with a maturity in fiscal 2017. The $113 million increase over the $36 million outstanding as of October 31, 2011 principally relates to borrowings made to fund acquisitions in November 2011 and March 2012, net of payments made on the revolving credit facility. See Note 2, Acquisitions, and Note 5, Long Term Debt, of the Notes to Condensed Consolidated Financial Statements for additional details.

As part of the agreement to acquire a subsidiary by the ETG in the second quarter of fiscal 2012, we may be obligated to pay contingent consideration of up to $14.6 million in aggregate should the acquired entity meet certain earnings objectives during each of the first five years following the acquisition. As of the acquisition date, we recorded an accrual for $10.8 million representing the fair value of the contingent consideration, which was determined using a probability-based scenario analysis approach. Subsequent to the acquisition date, changes in the fair value of contingent consideration will be recorded in our condensed consolidated statements of operations. Changes in the fair value of this contingent consideration were not material during the period ended July 31, 2012. As of July 31, 2012, the estimated amount of such contingent consideration to be paid within the next twelve months of $1.6 million is included in accrued expenses and other current liabilities and the remaining $9.3 million is included in other long-term liabilities in our Condensed Consolidated Balance Sheet. See Note 2, Acquisitions, and Note 7, Fair Value Measurements, of the Notes to Condensed Consolidated Financial Statements for additional details.

During the first nine months of fiscal 2012, we entered into several facility operating lease commitments through certain subsidiaries of the FSG and ETG. The aforementioned commitments are principally attributed to operational expansion and/or the extension of facility leases by these subsidiaries. The aggregate minimum lease payments for these facilities are estimated to be $.2 million for the remainder of fiscal 2012, $1.5 million in fiscal 2013, $1.6 million in each of 2014, 2015 and 2016, $1.1 million in fiscal 2017 and $1.0 million thereafter.

Off-Balance Sheet Arrangements

Guarantees

We have arranged for a standby letter of credit for $1.5 million to meet the security requirement of our insurance company for potential workers’ compensation claims, which is supported by our revolving credit facility.

31

Additional Contingent Purchase Consideration

As part of the agreement to acquire a subsidiary by the ETG in fiscal 2007, we may have been obligated to pay additional purchase consideration of up to 73 million Canadian dollars in aggregate, which translates to approximately $71 million U.S. dollars based on the June 30, 2012 exchange rate, had the subsidiary met certain earnings objectives through June 2012. Based on the subsidiary’s actual earnings through the measurement period, no additional purchase consideration will be paid.

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. We 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 we will make the required additional disclosures as applicable.

In May 2011, the FASB issued ASU 2011-04, “Amendments to Achieve Common Fair Value Measurement and Disclosure Requirements in U.S. GAAP and IFRSs,” which amends current fair value measurement and disclosure guidance to converge with International Financial Reporting Standards and provides increased transparency around valuation inputs and investment categorization. ASU 2011-04 also requires new disclosures about qualitative and quantitative information regarding the unobservable inputs used in a fair value measurement that is categorized within Level 3 of the fair value hierarchy. We adopted ASU 2011-04 in the second quarter of fiscal 2012, resulting in only expanded fair value disclosures and no effect on our results of operations, financial position or cash flows.

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. We are currently evaluating which presentation option we will elect, but the adoption of these provisions will have no effect on our 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 the complexity and cost of performing a quantitative test for impairment of goodwill 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

32

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. Early adoption is permitted. The adoption of this guidance is not expected to have a material impact on our results of operations, financial position or cash flows.

In July 2012, the FASB issued ASU 2012-02, “Testing Indefinite-Lived Intangible Assets for Impairment,” which is intended to reduce the complexity and cost of performing a quantitative test for impairment of indefinite-lived intangible assets by permitting an entity the option to perform a qualitative evaluation about the likelihood that an indefinite-lived intangible asset is impaired in order to determine whether it should calculate the fair value of the asset. 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 an indefinite-lived intangible asset is less than its carrying amount. ASU 2012-02 is effective for annual and interim impairment tests performed for fiscal years beginning after September 15, 2012, or in fiscal 2013 for HEICO’s annual impairment test. Early adoption is permitted. The adoption of this guidance is not expected to have a material impact on our results of operations, financial position or cash flows.

Forward-Looking Statements

Certain statements in this report constitute “forward-looking statements” within the meaning of the Private Securities Litigation Reform Act of 1995. All statements contained herein that are not clearly historical in nature may be forward-looking and the words “anticipate,” “believe,” “expect,” “estimate” and similar expressions are generally intended to identify forward-looking statements. Any forward-looking statements contained herein, in press releases, written statements or other documents filed with the Securities and Exchange Commission or in communications and discussions with investors and analysts in the normal course of business through meetings, phone calls and conference calls, concerning our operations, economic performance and financial condition are subject to risks, uncertainties and contingencies. We have based these forward-looking statements on our current expectations and projections about future events. All forward-looking statements involve risks and uncertainties, many of which are beyond our control, which may cause actual results, performance or achievements to differ materially from anticipated results, performance or achievements. Also, forward-looking statements are based upon management’s estimates of fair values and of future costs, using currently available information. Therefore, actual results may differ materially from those expressed or implied in those statements. Factors that could cause such differences include: lower demand for commercial air travel or airline fleet changes, which could cause lower demand for our goods and services; product specification costs and requirements, which could cause an increase to our costs to complete contracts; governmental and regulatory demands, export policies and restrictions, reductions in defense, space or homeland security spending by U.S. and/or foreign customers or competition from existing and new competitors, which could reduce our sales; our ability to introduce new products and product pricing levels,

33

which could reduce our sales or sales growth; and our ability to make acquisitions and achieve operating synergies from acquired businesses, customer credit risk, interest and income tax rates and economic conditions within and outside of the aviation, defense, space, medical, telecommunication and electronics industries, which could negatively impact our costs and revenues. We undertake no obligation to publicly update or revise any forward-looking statement, whether as a result of new information, future events or otherwise, except to the extent required by applicable law.

Item 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

There have not been any material changes in our assessment of HEICO’s sensitivity to market risk that was disclosed in Item 7A, “Quantitative and Qualitative Disclosures About Market Risk,” in our Annual Report on Form 10-K for the year ended October 31, 2011.

Item 4. CONTROLS AND PROCEDURES

Evaluation of Disclosure Controls and Procedures

Our management, with the participation of our Chief Executive Officer and our Chief Financial Officer, evaluated the effectiveness of our disclosure controls and procedures (as defined in Exchange Act Rules 13a-15(e) and 15d-15(e)) as of the end of the period covered by this quarterly report. Based upon that evaluation, our Chief Executive Officer and our Chief Financial Officer concluded that HEICO’s disclosure controls and procedures are effective as of the end of the period covered by this quarterly report.

Changes in Internal Control Over Financial Reporting

There have been no changes in the Company’s internal control over financial reporting during the third quarter ended July 31, 2012 that have materially affected, or are reasonably likely to materially affect, the Company’s internal control over financial reporting.

Business Combinations [Abstract]

Business Combination Disclosure [Text Block]

ACQUISITIONS

On November 22, 2011, the Company, through its HEICO Electronic Technologies Corp. (“HEICO Electronic”) subsidiary, acquired Switchcraft, Inc. (“Switchcraft”) through the purchase of all of the stock of Switchcraft’s parent company, Switchcraft Holdco, Inc., for approximately $143.2 million, net of cash acquired. The purchase price of this acquisition was paid in cash, principally using proceeds from the Company’s revolving credit facility. Switchcraft is a leading designer and manufacturer of high performance, high reliability and harsh environment electronic connectors and other interconnect products. This acquisition is consistent with HEICO’s practice of acquiring outstanding, niche designers and manufacturers of critical components in the aerospace and electronic industries and will further enable the Company to broaden its product offerings, technologies and customer base.

The following table summarizes the allocation of the purchase price of Switchcraft to the estimated fair values of the tangible and identifiable intangible assets acquired and liabilities assumed (in thousands).

Assets acquired:
Goodwill		$76,581
Identifiable intangible assets	72,500
Inventories	13,086
Property, plant and equipment	10,166
Accounts receivable	6,123
Other assets	1,570
Total assets acquired, excluding cash		$180,026
Liabilities assumed:
Deferred income taxes		$30,448
Accrued expenses	2,252
Income taxes payable	2,016
Accounts payable	1,889
Other liabilities	258
Total liabilities assumed		$36,863
Net assets acquired, excluding cash		$143,163

The allocation of the purchase price to the tangible and identifiable assets acquired and liabilities assumed is preliminary until the Company obtains final information regarding their fair values. The primary items that generated the goodwill recognized were the premiums paid by the Company for the future earnings potential of Switchcraft and the value of its assembled workforce that do not qualify for separate recognition. The operating results of Switchcraft were included in the Company’s results of operations from the effective acquisition date. The Company’s consolidated net sales and net income attributable to HEICO for the nine months ended July 31, 2012, includes approximately $40.1 million and $2.5 million, respectively, from the acquisition of Switchcraft. The Company’s consolidated net sales and net income attributable to HEICO for the three months ended July 31, 2012, includes approximately $14.6 million and $1.0 million, respectively, from the acquisition of Switchcraft.

The following table presents unaudited pro forma financial information for the nine and three months ended July 31, 2011 as if the acquisition of Switchcraft had occurred as of November 1, 2010 (in thousands).

	Nine months ended		Three months ended
	July 31, 2011		July 31, 2011
Net sales		$600,593		$212,480
Net income from consolidated operations		$74,877		$27,944
Net income attributable to HEICO		$58,142		$21,954
Net income per share attributable to HEICO shareholders:
Basic		$1.12		$.42
Diluted		$1.09		$.41

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, 2010. The unaudited pro forma financial information includes adjustments to historical amounts such as additional amortization expense related to intangible assets acquired, increased interest expense associated with borrowings to finance the acquisition and inventory purchase accounting adjustments charged to cost of sales as the inventory is sold. Had the acquisition been consummated as of November 1, 2010, 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 the nine and three months ended July 31, 2012 would not have been materially different than the reported amounts.

In March 2012, the Company, through HEICO Electronic, acquired the business and substantially all of the assets of Ramona Research, Inc. (“Ramona Research”). Ramona Research designs and manufactures RF and microwave amplifiers, transmitters and receivers primarily used to support military communications on unmanned aerial systems, other aircraft, helicopters and ground-based data/communications systems. The purchase price of this acquisition was paid in cash principally using proceeds from the Company’s revolving credit facility. The total consideration includes an accrual of approximately $10.8 million representing the fair value of contingent consideration in aggregate that the Company may be obligated to pay should Ramona Research meet certain earnings objectives during each of the first five years following the acquisition. The maximum amount of contingent consideration that the Company could be required to pay is $14.6 million in aggregate. See Note 7, Fair Value Measurements, for additional information regarding the Company’s contingent consideration obligation.

In April 2012, the Company, through a subsidiary of HEICO Electronic, acquired certain aerospace assets of Moritz Aerospace, Inc. (“Moritz Aerospace”) in an aerospace product line acquisition. The Moritz Aerospace product line designs and manufactures next generation wireless cabin control systems, solid state power distribution and management systems and fuel level sensing systems for business jets and for general aviation, as well as for the military/defense market segments. The purchase price of this acquisition was paid using cash provided by operating activities.

The total consideration and related allocation to the tangible and identifiable intangible assets acquired and liabilities assumed for the acquisitions of Ramona Research and Moritz Aerospace is not material or significant to the Company’s condensed consolidated financial statements. The operating results of Ramona Research and Moritz Aerospace were included in the Company’s results of operations from the effective acquisition dates. The amount of net sales and earnings of Ramona Research and Moritz Aerospace included in the Condensed Consolidated Statements of Operations is not material. Had the Ramona Research and Moritz Aerospace acquisitions been consummated as of November 1, 2010, 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 the nine and three months ended July 31, 2012 and 2011 would not have been materially different than the reported amounts.

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 the third quarter of fiscal 2012, the Company, through HEICO Electronic, paid $10.1 million of such additional purchase consideration using cash provided by operating activities. During the second and third quarters of fiscal 2011, the Company, through HEICO Electronic, paid $4.1 million and $1.3 million, respectively, of such additional purchase consideration using cash provided by operating activities. During the third quarter of fiscal 2011, HEICO Electronic accrued $1.2 million of additional purchase consideration related to a prior year acquisition for which the earnings objectives were met during fiscal 2011. The amount paid in fiscal 2012 and the amounts paid and accrued in fiscal 2011 were based on a multiple of the respective 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.

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

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 nine months endedJuly 31, 2012 are not necessarily indicative of the results which may be expected for the entire fiscal year.

StockSplit

In March 2012, 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 25, 2012 in the form of a 25% stock dividend distributed to shareholders of record as of April 13, 2012. All applicable share and per share information has been adjusted retrospectively to give effect to the 5-for-4 stock split.

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 May 2011, the FASB issued ASU 2011-04, “Amendments to Achieve Common Fair Value Measurement and Disclosure Requirements in U.S. GAAP and IFRSs,” which amends current fair value measurement and disclosure guidance to converge with International Financial Reporting Standards and provides increased transparency around valuation inputs and investment categorization. ASU 2011-04 also requires new disclosures about qualitative and quantitative information regarding the unobservable inputs used in a fair value measurement that is categorized within Level 3 of the fair value hierarchy. The Company adopted ASU 2011-04 in the second quarter of fiscal 2012, resulting in only expanded fair value disclosures and no impact on the Company’s results of operations, financial position or cash flows.

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 the complexity and cost of performing a quantitative test for impairment of goodwill 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. Early adoption is permitted. 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.

In July 2012, the FASB issued ASU 2012-02, “Testing Indefinite-Lived Intangible Assets for Impairment,” which is intended to reduce the complexity and cost of performing a quantitative test for impairment of indefinite-lived intangible assets by permitting an entity the option to perform a qualitative evaluation about the likelihood that an indefinite-lived intangible asset is impaired in order to determine whether it should calculate the fair value of the asset. 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 an indefinite-lived intangible asset is less than its carrying amount. ASU 2012-02 is effective for annual and interim impairment tests performed for fiscal years beginning after September 15, 2012, or in fiscal 2013 for HEICO’s annual impairment test. Early adoption is permitted. 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.

Business Acquisition, Pro Forma Information [Table Text Block]

The following table presents unaudited pro forma financial information for the nine and three months ended July 31, 2011 as if the acquisition of Switchcraft had occurred as of November 1, 2010 (in thousands).

	Nine months ended		Three months ended
	July 31, 2011		July 31, 2011
Net sales		$600,593		$212,480
Net income from consolidated operations		$74,877		$27,944
Net income attributable to HEICO		$58,142		$21,954
Net income per share attributable to HEICO shareholders:
Basic		$1.12		$.42
Diluted		$1.09		$.41

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, 2010. The unaudited pro forma financial information includes adjustments to historical amounts such as additional amortization expense related to intangible assets acquired, increased interest expense associated with borrowings to finance the acquisition and inventory purchase accounting adjustments charged to cost of sales as the inventory is sold. Had the acquisition been consummated as of November 1, 2010, 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 the nine and three months ended July 31, 2012 would not have been materially different than the reported amounts.

LONG-TERM DEBT

Long-term debt consists of the following (in thousands):

	July 31, 2012			October 31, 2011
Borrowings under revolving credit facility		$149,000			$36,000
Capital lease and notes payable	3,919			4,158
	152,919			40,158
Less: Current maturities of long-term debt	(304		)	(335		)
		$152,615			$39,823

On December 14, 2011, the Company entered into a $670 million Revolving Credit Agreement (“New Credit Facility”) with a bank syndicate, which matures in December 2016. Under certain circumstances, the maturity of the New Credit Facility may be extended for two one-year periods. The New Credit Facility also includes a feature that will allow the Company to increase the New Credit Facility by $130 million, at its option, to become an $800 million facility through increased commitments from existing lenders or the addition of new lenders. The New Credit Facility may be used for working capital and general corporate needs of the Company, including capital expenditures and to finance acquisitions. The New Credit Facility replaced the $300 million Second Amended and Restated Revolving Credit Facility Agreement.

Advances under the New 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 interests and non-cash charges, or “leverage ratio”). The Base Rate is the highest of (i) the Prime Rate; (ii) the Federal Funds rate plus .50% per annum; and (iii) the Adjusted LIBO Rate determined on a daily basis for an Interest Period of one month plus 1.00% per annum, as such capitalized terms are defined in the New Credit Facility. The applicable margins for LIBOR-based borrowings range from .75% to 2.25%. The applicable margins for Base Rate borrowings range from 0% to 1.25%. A fee is charged on the amount of the unused commitment ranging from .125% to .35% (depending on the Company’s leverage ratio). The New Credit Facility also includes a $50 million sublimit for borrowings made in foreign currencies, letters of credit and swingline borrowings. Outstanding principal, accrued and unpaid interest and other amounts payable under the New Credit Facility may be accelerated upon an event of default, as such events are described in the New Credit Facility. The New Credit Facility is unsecured and contains covenants that require, among other things, the maintenance of a total 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 New Credit Facility would become secured by the capital stock owned in substantially all of the Company’s subsidiaries.

As of July 31, 2012 and October 31, 2011, the weighted average interest rate on borrowings under the Company’s revolving credit facility was 1.3% and .9%, respectively. The revolving credit facility contains both financial and non-financial covenants. As of July 31, 2012, the Company was in compliance with all such covenants.

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 by operating segment for the nine months ended July 31, 2012 are as follows (in thousands):

	Segment					Consolidated Totals
	FSG		ETG
Balances as of October 31, 2011		$192,357		$251,045			$443,402

Other	309		—			309
Balances as of July 31, 2012		$192,666		$338,928			$531,594

The goodwill acquired pertains to the current year acquisitions described in Note 2, Acquisitions, and represents the residual value after the allocation of the total consideration to the tangible and identifiable intangible assets acquired and liabilities assumed. The adjustments to goodwill during fiscal 2012 represent additional purchase price consideration paid relating to a prior year acquisition for which the earnings objectives were met in fiscal 2012. See Note 2, Acquisitions, for additional information regarding additional contingent purchase consideration. The Company estimates that approximately $13 million of the goodwill recognized in fiscal 2012 will be deductible for income tax purposes.

Identifiable intangible assets consist of the following (in thousands):

	As of July 31, 2012							As of October 31, 2011
	Gross Carrying Amount		Accumulated Amortization			Net Carrying Amount		Gross Carrying Amount		Accumulated Amortization			Net Carrying Amount

		$177,183		($29,973	)		$147,210		$101,072		($22,915	)		$78,157

The increase in the gross carrying amount of customer relationships, intellectual property and non-amortizing trade names as of July 31, 2012 compared to October 31, 2011 principally relates to such intangible assets recognized in connection with acquisitions made during fiscal 2012 (see Note 2, Acquisitions). The weighted average amortization period of the customer relationships and intellectual property acquired is 10 years and 11 years, respectively.

Amortization expense related to intangible assets for the nine months endedJuly 31, 2012 and 2011 was $11.7 million and $5.4 million, respectively. Amortization expense related to intangible assets for the three months endedJuly 31, 2012 and 2011 was $4.2 million and $1.9 million, respectively. Amortization expense related to intangible assets for the remainder of fiscal 2012 is estimated to be $4.2 million. Amortization expense for each of the next five fiscal years and thereafter is estimated to be $16.1 million in fiscal 2013, $15.5 million in fiscal 2014, $14.0 million in fiscal 2015, $12.6 million in fiscal 2016, $12.0 million in fiscal 2017 and $37.5 million thereafter.

INCOME TAXES

As of July 31, 2012, the Company’s liability for gross unrecognized tax benefits related to uncertain tax positions was $1.8 million of which $1.2 million 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 for the nine months endedJuly 31, 2012 is as follows (in thousands):

Balance as of October 31, 2011		$1,834
Increases related to prior year tax positions	552
Decreases related to prior year tax positions	(240		)
Increases related to current year tax positions	216
Settlements	(52		)
Lapse of statutes of limitations	(485		)
Balance as of July 31, 2012		$1,825

There were no material changes in the liability for unrecognized tax positions resulting from tax positions taken during the current or a prior year, settlements with other taxing authorities or a lapse of applicable statutes of limitations. The accrual of interest and penalties related to the unrecognized tax benefits was not material for the nine months endedJuly 31, 2012. Further, the Company does not expect the total amount of unrecognized tax benefits to materially change in the next twelve months.    

During the third quarter of fiscal 2012, the Company filed its fiscal 2011 U.S. federal and state tax returns and recognized an aggregate benefit, which increased net income attributable to HEICO by $.9 million, from higher fiscal 2011 research and development tax credits. The higher research and development tax credits reflect the finalization of a study of qualifying fiscal 2011 research and development activities and a reduction in the liability for gross unrecognized research and development related tax positions due to a lapse of the statute of limitations.

During the third quarter of fiscal 2011, the Company filed its fiscal 2010 U.S. federal and state tax returns and amended certain prior year state tax returns and recognized an aggregate benefit, which increased net income attributable to HEICO by $2.0 million, principally from state income apportionment updates ($.9 million) and higher research and development tax credits ($.9 million).

The Company's effective tax rate in the first nine months of fiscal 2012 increased to 33.3% from 29.7% in the first nine months of fiscal 2011. The effective tax rate for the first nine months of fiscal 2011 reflects the aforementioned benefit from state income apportionment updates recognized upon the filing of the Company’s fiscal 2010 state tax returns and the amendment of certain prior year state tax returns in the third quarter of fiscal 2011. The increase in the effective tax rate in fiscal 2012 is also due to the retroactive extension of Section 41 of the Internal Revenue Code, “Credit for Increasing Research Activities,” to cover the period from January 1, 2010 to December 31, 2011, which resulted in the recognition of an income tax credit for qualified research and development activities for the last ten months of fiscal 2010 in the first quarter of fiscal 2011 and reduced the recognition of such income tax credit to just the first two months of qualifying research and development activities in fiscal 2012. In addition, the increase reflects a higher effective state income tax rate attributable to a fiscal 2012 acquisition and changes in certain state tax laws which impacted state apportionment factors. During fiscal 2011 and 2012, the Company purchased certain noncontrolling interests that also contributed to the comparative increase in the effective tax rate for the first nine months of fiscal 2012.

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 and are valued using a market approach. Certain other assets of the LCP represent investments in money market funds that are classified within Level 1. The majority of the assets of the Company’s other deferred compensation plan are principally invested in equity securities, mutual funds and money market funds that are classified within Level 1. A portion of the assets within the other deferred compensation plan is currently invested in a fund that invests in future and forward contracts, most of which are privately negotiated with counterparties without going through a public exchange and that use trading methods that are proprietary and confidential. These assets are therefore classified within Level 3 and are valued using a market approach with corresponding gains and losses reported within other income in the Company’s Condensed Consolidated Statements of Operations. The assets of both plans are held within irrevocable trusts and classified within other assets in the Company’s Condensed Consolidated Balance Sheets and have an aggregate value of $39.5 million as of July 31, 2012 and $31.1 million as of October 31, 2011, of which the LCP related assets were $35.3 million and $27.0 million as of July 31, 2012 and October 31, 2011, respectively. The related liabilities of the two deferred compensation plans are included within other long-term liabilities in the Company’s Condensed Consolidated Balance Sheets and have an aggregate value of $39.0 million as of July 31, 2012 and $30.8 million as of October 31, 2011, of which the LCP related liability was $34.8 million and $26.7 million as of July 31, 2012 and October 31, 2011, respectively.

As part of the agreement to acquire a subsidiary by the ETG in the second quarter of fiscal 2012, the Company may be obligated to pay contingent consideration of up to $14.6 million in aggregate should the acquired entity meet certain earnings objectives during each of the first five years following the acquisition. The $10.8 million estimated fair value of the contingent consideration as of the acquisition date is classified within Level 3 and was determined using a probability-based scenario analysis approach. Under this method, a set of discrete potential future subsidiary earnings was determined using internal estimates based on various revenue growth rate assumptions for each scenario that ranged from a compound annual growth rate of (8%) to 20%. A probability of likelihood was assigned to each discrete potential future earnings estimate and the resultant contingent consideration was calculated. The resulting probability-weighted contingent consideration amounts were discounted using a weighted average discount rate of 3.5% reflecting the credit risk of a market participant. Significant changes to either the revenue growth rates, related earnings or the discount rate could result in a material change to the amount of contingent consideration accrued and such changes will be recorded in the Company’s condensed consolidated statements of operations. Changes in the fair value of this contingent consideration were not material during the period ended July 31, 2012. As of July 31, 2012, the estimated amount of such contingent consideration to be paid within the next twelve months of $1.6 million is included in accrued expenses and other current liabilities and the remaining $9.3 million is included in other long-term liabilities in the Company’s Condensed Consolidated Balance Sheet.

Changes in the Company’s assets and liabilities measured at fair value on a recurring basis using unobservable inputs (Level 3) for the nine months endedJuly 31, 2012 are as follows (in thousands):

	Assets		Liabilities
Balances as of October 31, 2011		$573		$—
Contingent consideration related to acquisition	—		10,778
Increase in value of contingent consideration	—		143
Total unrealized gains	4		—
Balances as of July 31, 2012		$577		$10,921

The Company did not have any transfers between Level 1 and Level 2 fair value measurements during the nine months ended July 31, 2012.

The carrying amounts of the Company’s cash and cash equivalents, accounts receivable, trade accounts payable and accrued expenses and other current liabilities approximate fair value as of July 31, 2012 due to the relatively short maturity of the respective instruments. The carrying amount of long-term debt approximates fair value due to its variable interest rates.

REDEEMABLE NONCONTROLLING INTERESTS

Temporary Equity Redeemable Noncontrolling Interests [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 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 July 31, 2012, management’s estimate of the aggregate Redemption Amount of all Put Rights that the Company would be required to pay is approximately $59 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, 2012 redeemable at fair value is approximately $34 million and the portion redeemable based solely on a multiple of future earnings is approximately $25 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 February 2012, the Company, through its HEICO Aerospace Holdings Corp. (“HEICO Aerospace”) subsidiary, acquired an additional 6.7% equity interest in one of its subsidiaries, which increased the Company’s ownership interest to 86.7%. The purchase price of the redeemable noncontrolling interests acquired was paid using cash provided by operating activities.

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 nine months endedJuly 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 May 2011, the FASB issued ASU 2011-04, “Amendments to Achieve Common Fair Value Measurement and Disclosure Requirements in U.S. GAAP and IFRSs,” which amends current fair value measurement and disclosure guidance to converge with International Financial Reporting Standards and provides increased transparency around valuation inputs and investment categorization. ASU 2011-04 also requires new disclosures about qualitative and quantitative information regarding the unobservable inputs used in a fair value measurement that is categorized within Level 3 of the fair value hierarchy. The Company adopted ASU 2011-04 in the second quarter of fiscal 2012, resulting in only expanded fair value disclosures and no impact on the Company’s results of operations, financial position or cash flows.

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 the complexity and cost of performing a quantitative test for impairment of goodwill 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. Early adoption is permitted. 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.

In July 2012, the FASB issued ASU 2012-02, “Testing Indefinite-Lived Intangible Assets for Impairment,” which is intended to reduce the complexity and cost of performing a quantitative test for impairment of indefinite-lived intangible assets by permitting an entity the option to perform a qualitative evaluation about the likelihood that an indefinite-lived intangible asset is impaired in order to determine whether it should calculate the fair value of the asset. 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 an indefinite-lived intangible asset is less than its carrying amount. ASU 2012-02 is effective for annual and interim impairment tests performed for fiscal years beginning after September 15, 2012, or in fiscal 2013 for HEICO’s annual impairment test. Early adoption is permitted. 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.

Accrued Customer Rebates and Credits

The aggregate amount of accrued customer rebates and credits included within accrued expenses and other current liabilities in the accompanying Condensed Consolidated Balance Sheets was $10.3 million and $9.6 million as of July 31, 2012 and October 31, 2011, respectively. The total customer rebates and credits deducted within net sales for the nine months endedJuly 31, 2012 and 2011 was $2.1 million and $6.7 million, respectively. The total customer rebates and credits deducted within net sales for the three months ended July 31, 2012 and 2011 was $1.0 million and $2.3 million, respectively. The decrease in customer rebates and credits principally reflects a reduction in the net sales volume of certain customers eligible for rebates as well as a reduction in associated rebate percentages.

SUBSEQUENT EVENT

In August 2012, the Company, through its HEICO Flight Support Corp. subsidiary, acquired 84% of the assets and assumed certain liabilities of CSI Aerospace, Inc. (“CSI Aerospace”). CSI Aerospace is a leading repair and overhaul provider of specialized components for airlines, military and other aerospace related organizations. The remaining 16% interest continues to be owned by certain members of CSI Aerospace’s management team. The purchase price was paid in cash principally using proceeds from the Company’s revolving credit facility. The total consideration for this acquisition and related allocation to the tangible and identifiable intangible assets acquired and liabilities assumed is not material or significant to the Company’s condensed consolidated financial statements.
