	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, 2013. The October 31, 2013 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, statements of comprehensive income, statements of shareholders' equity and statements of cash flows for such interim periods presented. The results of operations for the three months ended January 31, 2014 are not necessarily indicative of the results which may be expected for the entire fiscal year.
	Stock Split
	All applicable fiscal 2013 share and per share information has been adjusted retrospectively to reflect a 5-for-4 stock split effected in October 2013.
	New Accounting Pronouncements
	In February 2013, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2013-02, “Reporting of Amounts Reclassified Out of Accumulated Other Comprehensive Income,” which requires disclosure about changes in and amounts reclassified out of accumulated other comprehensive income by component. In addition, an entity is required to present, either on the face of the statement of operations or in the notes, significant amounts reclassified out of accumulated other comprehensive income by the respective line items of net income, but only if the amount reclassified is required to be reclassified to net income in its entirety in the same reporting period. For amounts that are not required to be reclassified in their entirety to net income, an entity is required to cross-reference to other disclosures that provide additional detail about those amounts. The Company adopted ASU 2013-02 in the first quarter of fiscal 2014, resulting in only expanded disclosure regarding the changes in accumulated other comprehensive income and no impact on the Company's consolidated results of operations, financial position or cash flows.
	In March 2013, the FASB issued ASU 2013-05, “Parent's Accounting for the Cumulative Translation Adjustment upon Derecognition of Certain Subsidiaries or Groups of Assets within a Foreign Entity or of an Investment in a Foreign Entity,” which clarifies the applicable guidance for the release of any cumulative translation adjustments into net earnings. ASU 2013-05 specifies that the entire amount of cumulative translation adjustments should be released into earnings when an entity ceases to have a controlling financial interest in a subsidiary or group of assets within a consolidated foreign entity and the sale or transfer results in the complete or substantially complete liquidation of the investment in the foreign entity. ASU 2013-05 is effective prospectively for fiscal years and interim reporting periods within those years beginning after December 15, 2013, or in fiscal 2015 for HEICO. Early adoption is permitted. The Company is currently evaluating the effect, if any, the adoption of this guidance will have on its consolidated results of operations, financial position or cash flows.

	Expected return on plan assets			$185
	Interest cost		153
	Net pension income			$32
	Redeemable Noncontrolling Interests
	The holders of equity interests in certain of the Company's subsidiaries have put rights that may be exercised on varying dates causing the Company to give cash consideration to purchase their equity interests based on fair value or a formula that management intended to reasonably approximate fair value based solely on a multiple of future earnings over a measurement period. Management's estimate of the aggregate redemption amount of all put rights that the Company could be required to pay at varying dates through fiscal 2022 is as follows (in thousands):
		31-Jan-14			31-Oct-13

Amortization expense related to intangible assets for the remainder of fiscal 2014 is estimated to be $20.9 million. Amortization expense for each of the next five fiscal years and thereafter is estimated to be $26.1 million in fiscal 2015, $24.2 million in fiscal 2016, $23.1 million in fiscal 2017, $20.9 million in fiscal 2018, $18.6 million in fiscal 2019 and $43.5 million thereafter.

	As of January 31, 2014 and October 31, 2013, the weighted average interest rate on borrowings under the Company’s revolving credit facility was 1.3%. The revolving credit facility contains both financial and non-financial covenants. As of January 31, 2014, the Company was in compliance with all such covenants.
	In November 2013, the Company entered into an amendment to extend the maturity date of its revolving credit facility one year to December 2018 and to increase the aggregate principal amount to $800 million. Furthermore, the amendment includes a feature that will allow the Company to increase the aggregate principal amount by an additional $200 million to become a $1.0 billion facility through increased commitments from existing lenders or the addition of new lenders.

	As of January 31, 2014, the Company’s liability for gross unrecognized tax benefits related to uncertain tax positions was $1.0 million of which $.7 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 three months ended January 31, 2014 is as follows (in thousands):
	Balance as of October 31, 2013		$1,072
	Increases related to current year tax positions	27
	Settlements	(22		)
	Lapse of statutes of limitations	(60		)
	Balance as of January 31, 2014		$1,017
	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 three months ended January 31, 2014. Further, the Company does not expect the total amount of unrecognized tax benefits to materially change in the next twelve months.
	The Company’s effective tax rate in the first quarter of fiscal 2014 increased to 33.9% from 27.8% in the first quarter of fiscal 2013. The increase is principally due to an income tax credit for qualified research and development activities for the last ten months of fiscal 2012 that was recognized in the first quarter of fiscal 2013 resulting from the retroactive extension of Section 41 of the Internal Revenue Code, "Credit for Increasing Research Activities," in January 2013 to cover the two-year period from January 1, 2012 to December 31, 2013 and the expiration of Section 41 on December 31, 2013 that limited the tax credit recognized in the first quarter of fiscal 2014 to just the first two months of fiscal 2014 qualified research and development activities. Additionally, the increase is partially the result of a larger income tax deduction recognized in the first quarter of fiscal 2013 under Section 404(k) of the Internal Revenue Code for the special and extraordinary cash dividend paid in December 2012 to participants of the HEICO Savings and Investment Plan holding HEICO common stock.

	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. The assets of the Company’s other deferred compensation plan are principally invested in equity securities, mutual funds, and money market deposit accounts that are classified within Level 1. The assets of both plans are held within irrevocable trusts and classified within other assets in the Company’s Condensed Consolidated Balance Sheets and have an aggregate value of $64.5 million as of January 31, 2014 and $57.6 million as of October 31, 2013, of which the LCP related assets were $59.4 million and $52.7 million as of January 31, 2014 and October 31, 2013, 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 $63.9 million as of January 31, 2014 and $56.9 million as of October 31, 2013, of which the LCP related liability was $58.8 million and $51.9 million as of January 31, 2014 and October 31, 2013, respectively.
	As part of the agreement to acquire a subsidiary by the ETG in fiscal 2013, the Company may have been obligated to pay contingent consideration of up to $20.0 million should the acquired entity have met certain earnings objectives during the last three months of the calendar year of acquisition and may be obligated to pay contingent consideration of up to $30.0 million should the acquired entity meet certain earnings objectives during the subsequent two calendar years (2014 and 2015). In December 2013, the acquired entity incurred unanticipated costs associated with certain contracts for which revenue is recognized on the percentage-of-completion method and as a result, did not meet its calendar 2013 related earnings objectives. Accordingly, the $7.0 million contingent consideration accrued as of October 31, 2013 was recorded as a reduction to selling, general and administrative expenses in the Company's Condensed Consolidated Statement of Operations for the three months ended January 31, 2014. The estimated fair value of the contingent consideration for the calendar 2014 and 2015 earnings period was $13.7 million as of both January 31, 2014 and October 31, 2013.
	As part of the agreement to acquire a subsidiary by the ETG in fiscal 2012, the Company may be obligated to pay contingent consideration of up to $12.9 million in aggregate should the acquired entity meet certain earnings objectives during each of the next four years following the first anniversary date of the acquisition. As of January 31, 2014 and October 31, 2013, the estimated fair value of the contingent consideration was $8.5 million and $8.6 million, respectively.
	The estimated fair values of the contingent consideration arrangements described above are classified within Level 3 and were determined using a probability-based scenario analysis approach. Under this method, a set of discrete potential future subsidiary earnings were determined using internal estimates based on various revenue growth rate assumptions for each scenario. 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 reflecting the credit risk of a market participant. Changes in 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.
	The Level 3 inputs used to derive the estimated fair values of the contingent consideration as of January 31, 2014 were as follows:
		Fiscal 2013 Subsidiary		Fiscal 2012 Subsidiary
	Compound annual revenue growth rate range	(4%) - 31%		(5%) - 18%
	Weighted average discount rate	2.70%		2.80%
	Changes in the Company’s contingent consideration measured at fair value on a recurring basis using unobservable inputs (Level 3) for the three months ended January 31, 2014 are as follows (in thousands):
		Liabilities
	Balances as of October 31, 2013		$29,310

	under the following captions:
	Accrued expenses and other current liabilities		$—
	Other long-term liabilities		$22,264
			$22,264
	The Company did not have any transfers between Level 1 and Level 2 fair value measurements during the three months ended January 31, 2014.
	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 January 31, 2014 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.

	Consistent with the Company's past practice of increasing its ownership in certain non-wholly-owned subsidiaries, on February 18, 2014, HEICO Corporation acquired the 20% noncontrolling interest held by its partner, Lufthansa Technik AG (“LHT”), in four of the Company's existing subsidiaries principally operating in the specialty products and distribution businesses within its HEICO Aerospace Holdings Corp. subsidiary (the “Transaction”). Pursuant to the Transaction, HEICO Aerospace Holdings Corp. declared dividends proportional to the ownership (80%/20%) to HEICO and LHT, and HEICO transferred the businesses to the HEICO Flight Support Corp., a wholly-owned subsidiary of HEICO. HEICO did not record any gain or loss in connection with the transaction. LHT’s dividend approximates $67 million and will be funded through a borrowing under the Company’s existing credit facility. After the Transaction, LHT remains a 20% owner in HEICO Aerospace Holdings Corp., a leading producer of PMA parts and component repair and overhaul services.

	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, 2013. The October 31, 2013 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, statements of comprehensive income, statements of shareholders' equity and statements of cash flows for such interim periods presented. The results of operations for the three months ended January 31, 2014 are not necessarily indicative of the results which may be expected for the entire fiscal year.

	New Accounting Pronouncements
	In February 2013, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2013-02, “Reporting of Amounts Reclassified Out of Accumulated Other Comprehensive Income,” which requires disclosure about changes in and amounts reclassified out of accumulated other comprehensive income by component. In addition, an entity is required to present, either on the face of the statement of operations or in the notes, significant amounts reclassified out of accumulated other comprehensive income by the respective line items of net income, but only if the amount reclassified is required to be reclassified to net income in its entirety in the same reporting period. For amounts that are not required to be reclassified in their entirety to net income, an entity is required to cross-reference to other disclosures that provide additional detail about those amounts. The Company adopted ASU 2013-02 in the first quarter of fiscal 2014, resulting in only expanded disclosure regarding the changes in accumulated other comprehensive income and no impact on the Company's consolidated results of operations, financial position or cash flows.
	In March 2013, the FASB issued ASU 2013-05, “Parent's Accounting for the Cumulative Translation Adjustment upon Derecognition of Certain Subsidiaries or Groups of Assets within a Foreign Entity or of an Investment in a Foreign Entity,” which clarifies the applicable guidance for the release of any cumulative translation adjustments into net earnings. ASU 2013-05 specifies that the entire amount of cumulative translation adjustments should be released into earnings when an entity ceases to have a controlling financial interest in a subsidiary or group of assets within a consolidated foreign entity and the sale or transfer results in the complete or substantially complete liquidation of the investment in the foreign entity. ASU 2013-05 is effective prospectively for fiscal years and interim reporting periods within those years beginning after December 15, 2013, or in fiscal 2015 for HEICO. Early adoption is permitted. The Company is currently evaluating the effect, if any, the adoption of this guidance will have on its consolidated results of operations, financial position or cash flows.
