Significant Accounting Policies [Text Block]

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Nature of Business

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

Basis of Presentation

The consolidated financial statements include the accounts of HEICO Corporation and its subsidiaries, all of which are wholly owned except for HEICO Aerospace, which is 20% owned by Lufthansa Technik AG ("LHT"), the technical services subsidiary of Lufthansa German Airlines. In addition, HEICO Aerospace consolidates two subsidiaries which are 80.1% and 82.3% owned, respectively, and a joint venture, which is 84% owned. Also, HEICO Flight Support Corp. consolidates three subsidiaries which are 80.1%, 80.1%, and 84% owned, respectively. Furthermore, HEICO Electronic consolidates three subsidiaries, which are 80.1%, 82.5%, and 95.9% owned, respectively, and a wholly owned subsidiary of HEICO Electronic consolidates a subsidiary which is 78% owned. See Note 11, Redeemable Noncontrolling Interests. All intercompany balances and transactions are eliminated.

Stock Splits

In September 2013 and 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 splits were effected as of October 23, 2013 and April 25, 2012, respectively, in the form of a 25% stock dividend distributed to shareholders of record as of October 11, 2013 and April 13, 2012, respectively. All applicable share and per share information has been adjusted retrospectively to give effect to the 5-for-4 stock splits.

Use of Estimates and Assumptions

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

Cash and Cash Equivalents

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

Accounts Receivable

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

Concentrations of Credit Risk

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

Inventory

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

The Company periodically evaluates the carrying value of inventory, giving consideration to factors such as its physical condition, sales patterns and expected future demand in order to estimate the amount necessary to write down any slow moving, obsolete or damaged inventory. These estimates could vary significantly from actual amounts based upon future economic conditions, customer inventory levels or competitive factors that were not foreseen or did not exist when the estimated write-downs were made. In accordance with industry practice, all inventories are classified as a current asset including portions with long production cycles, some of which may not be realized within one year.

Property, Plant and Equipment

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

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

Capital Leases

Assets acquired under capital leases are recorded at the lower of the fair value of the asset or the present value of the future minimum lease payments, excluding that portion of the payments representing executory costs. The discount rate used in determining the present value of the minimum lease payments is the lower of the rate implicit in the lease or the Company's incremental borrowing rate. Assets under capital leases are included in property, plant and equipment and are depreciated over the shorter of the lease term or the useful life of the leased asset. Lease payments under capital leases are recognized as a reduction of the capital lease obligation and as interest expense.

Business Combinations

The Company allocates the purchase price of acquired entities to the underlying tangible and identifiable intangible assets acquired and liabilities and any noncontrolling interests assumed based on their estimated fair values, with any excess recorded as goodwill. The operating results of acquired businesses are included in the Company’s results of operations beginning as of their effective acquisition dates. Acquisition costs are generally expensed as incurred and were not material in fiscal 2014, 2013 or 2012.

For contingent consideration arrangements, a liability is recognized at fair value as of the acquisition date with subsequent fair value adjustments recorded in operations. Information regarding additional contingent purchase consideration may be found in Note 2, Acquisitions and Note 7, Fair Value Measurements.

Goodwill and Other Intangible Assets

The Company tests goodwill for impairment annually as of October 31, or more frequently if events or changes in circumstances indicate that the carrying amount of goodwill may not be fully recoverable. In evaluating the recoverability of goodwill, the Company compares the fair value of each of its reporting units to its carrying value to determine potential impairment. If the carrying value of a reporting unit exceeds its fair value, the implied fair value of that reporting unit’s goodwill is to be calculated and an impairment loss is recognized in the amount by which the carrying value of the reporting unit’s goodwill exceeds its implied fair value, if any. The fair values of the Company's reporting units are determined by using a weighted average of a market approach and an income approach. Under the market approach, fair values are estimated using published market multiples for comparable companies. The Company calculates fair values under the income approach by taking estimated future cash flows that are based on internal projections and other assumptions deemed reasonable by management and discounting them using an estimated weighted average cost of capital.

The Company’s intangible assets not subject to amortization consist principally of its trade names. The Company’s intangible assets subject to amortization are amortized on the straight-line method (except for certain customer relationships amortized on an accelerated method) over the following estimated useful lives:



Customer relationships	6	to	10	years
Intellectual property	6	to	15	years
Licenses	10	to	17	years
Non-compete agreements	2	to	7	years
Patents	5	to	20	years
Trade names	5	to	10	years

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

Investments

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

Customer Rebates and Credits

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

Product Warranties

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

Defined Benefit Pension Plan

In connection with a fiscal 2013 acquisition, the Company assumed a frozen qualified defined benefit pension plan (the "Plan"). The Plan's benefits are based on employee compensation and years of service. However, since the Plan was closed to new participants effective December 31, 2004, the accrued benefit for Plan participants was fixed as of the date of acquisition. The Company uses an actuarial valuation to determine the projected benefit obligation of the Plan and records the difference between the fair value of the Plan's assets and the projected benefit obligation as of October 31 in its Consolidated Balance Sheets. Additionally, any actuarial gain or loss that arises during a fiscal year that is not recognized as a component of net periodic pension income or expense is recorded as a component of other comprehensive income or (loss), net of tax. See Note 10, Employee Retirement Plans, for additional information and disclosures about the Plan.

Revenue Recognition

Revenue from the sale of products and the rendering of services is recognized when title and risk of loss passes to the customer, which is generally at the time of shipment. Revenue from the rendering of services represented less than 10% of consolidated net sales for all periods presented. Revenue from certain fixed price contracts for which costs can be dependably estimated is recognized on the percentage-of-completion method, measured by the percentage of costs incurred to date to estimated total costs for each contract. The percentage of the Company’s net sales recognized under the percentage-of-completion method was approximately 3%, 1% and 1% in fiscal 2014, 2013 and 2012, respectively. Contract costs include all direct material and labor costs and those indirect costs related to contract performance, such as indirect labor, supplies, tools, repairs and depreciation costs. Selling, general and administrative costs are charged to expense as incurred.

Revisions in cost estimates as contracts progress have the effect of increasing or decreasing profits in the period of revision. Provisions for estimated losses on uncompleted contracts are made in the period in which such losses are determined. Variations in actual labor performance, changes to estimated profitability, and final contract settlements may result in revisions to cost estimates and are recognized in income in the period in which the revisions are determined. Changes in estimates pertaining to percentage-of-completion contracts did not have a material effect on net income from consolidated operations in fiscal 2014, 2013 or 2012.

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

For fixed price contracts in which costs cannot be dependably estimated, revenue is recognized on the completed-contract method. A contract is considered complete when all significant costs have been incurred or the item has been accepted by the customer. Progress billings and customer advances (“billings to date”) received on fixed price contracts accounted for under the completed-contract method are classified as a reduction to contracts in process (a component of inventories), if any, and any remaining amount is included in accrued expenses and other current liabilities.

Stock-Based Compensation

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

Income Taxes

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

The Company accounts for uncertainty in income taxes and evaluates tax positions utilizing a two-step process. The first step is to determine whether it is more-likely-than-not that a tax position will be sustained upon examination based on the technical merits of the position. The second step is to measure the benefit to be recorded from tax positions that meet the more-likely-than-not recognition threshold by determining the largest amount of tax benefit that is greater than 50 percent likely of being realized upon ultimate settlement and recognizing that amount in the financial statements. The Company’s policy is to recognize interest and penalties related to income tax matters as a component of income tax expense. Further information regarding income taxes can be found in Note 6, Income Taxes.

Redeemable Noncontrolling Interests

As further detailed in Note 11, Redeemable Noncontrolling Interests, the holders of equity interests in certain of the Company’s subsidiaries have rights (“Put Rights”) that require the Company to provide cash consideration for their equity interests (the “Redemption Amount”) at fair value or at a formula that management intended to reasonably approximate fair value based solely on a multiple of future earnings over a measurement period. The Put Rights are embedded in the shares owned by the noncontrolling interest holders and are not freestanding. The Company tracks the carrying cost of such redeemable noncontrolling interests at historical cost plus an allocation of subsidiary earnings based on ownership interest, less dividends paid to the noncontrolling interest holders. Redeemable noncontrolling interests are recorded outside of permanent equity at the higher of their carrying cost or management’s estimate of the Redemption Amount. The initial adjustment to record redeemable noncontrolling interests at the Redemption Amount results in a corresponding decrease to retained earnings. Subsequent adjustments to the Redemption Amount of redeemable noncontrolling interests may result in corresponding decreases or increases to retained earnings, provided any increases to retained earnings may only be recorded to the extent of decreases previously recorded. 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. Acquisitions of redeemable noncontrolling interests are treated as equity transactions.

Net Income per Share Attributable to HEICO Shareholders

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

As further detailed in “Redeemable Noncontrolling Interests” above, the portion of periodic adjustments to the carrying amount of redeemable noncontrolling interests based solely on a multiple of future earnings that reflect a redemption amount in excess of fair value affect net income attributable to HEICO for purposes of determining net income per share attributable to HEICO shareholders (see Note 12, Net Income per Share Attributable to HEICO Shareholders).

Foreign Currency Translation

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

Contingencies

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

New Accounting Pronouncements

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.

In May 2014, the FASB issued ASU 2014-09, “Revenue from Contracts with Customers,” which provides a comprehensive new revenue recognition model that will supersede nearly all existing revenue recognition guidance. Under ASU 2014-09, an entity will recognize revenue when it transfers promised goods or services to a customer at an amount that reflects the consideration it expects to receive in exchange for those goods or services. The guidance also requires additional disclosure about the nature, amount, timing and uncertainty of revenue and cash flows arising from customer contracts. ASU 2014-09 is effective for fiscal years and interim reporting periods within those years beginning after December 15, 2016, or in fiscal 2018 for HEICO. Early adoption is not permitted. ASU 2014-09 shall be applied either retrospectively to each prior reporting period presented or retrospectively with the cumulative effect of initially applying ASU 2014-09 recognized at the date of initial application. The Company is currently evaluating which transition method it will elect and the effect the adoption of this guidance will have on its consolidated results of operations, financial position or cash flows.

Acquisitions [Abstract]

Business Combination Disclosure [Text Block]

ACQUISITIONS

Reinhold Acquisition

On May 31, 2013, the Company, through its HEICO Flight Support Corp. subsidiary, acquired Reinhold Industries, Inc. ("Reinhold") through the acquisition of all of the outstanding stock of Reinhold's parent company for approximately $133.0 million, net of $8.0 million of cash acquired, in a transaction carried out by means of a merger. The purchase price of this acquisition was paid in cash, principally using proceeds from the Company’s revolving credit facility. Reinhold is a leading manufacturer of advanced niche components and complex composite assemblies for commercial aviation, defense and space applications. This acquisition is consistent with HEICO’s practice of acquiring outstanding, niche designers and manufacturers of critical components in the aerospace and defense 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 Reinhold to the estimated fair values of the tangible and identifiable intangible assets acquired and liabilities assumed (in thousands):



Assets acquired:
Goodwill		$76,424
Identifiable intangible assets	66,500
Inventories	10,753
Accounts receivable	8,830
Property, plant and equipment	7,994
Other assets	2,756
Total assets acquired, excluding cash		$173,257

Liabilities assumed:
Deferred income taxes		$25,613
Accrued expenses	6,994
Accounts payable	2,923
Defined benefit pension plan obligation, net	2,865
Accrued additional purchase consideration	1,499
Other liabilities	390
Total liabilities assumed		$40,284
Net assets acquired, excluding cash		$132,973

During fiscal 2014, the company recorded certain immaterial measurement period adjustments to the purchase price allocation of Reinhold, which are reflected in the table above. The primary items that generated the goodwill recognized were the premiums paid by the Company for the future earnings potential of Reinhold and the value of its assembled workforce that do not qualify for separate recognition. The operating results of Reinhold 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 fiscal 2013 includes approximately $30.8 million and $2.8 million, respectively, from the acquisition of Reinhold.

The following table presents unaudited pro forma financial information for fiscal 2012 as if the acquisition of Reinhold had occurred as of November 1, 2011 (in thousands):



	Year ended
	October 31, 2012
Net sales		$952,184
Net income from consolidated operations		$109,923
Net income attributable to HEICO		$88,382
Net income per share attributable to HEICO shareholders:
Basic		$1.34
Diluted		$1.33

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, 2011. 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, 2011, net sales, net income from consolidated operations, net income attributable to HEICO, and basic and diluted net income per share attributable to HEICO shareholders on a pro forma basis for fiscal 2013 would not have been materially different than the reported amounts.

Switchcraft Acquisition

On November 22, 2011, the Company, through HEICO Electronic, acquired Switchcraft, Inc. (“Switchcraft”) through the purchase of all of the stock of Switchcraft’s parent company, Switchcraft Holdco, Inc., for approximately $142.7 million, net of $3.7 million 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		$73,405
Identifiable intangible assets	72,500
Inventories	13,086
Property, plant and equipment	10,884
Accounts receivable	6,123
Other assets	1,358
Total assets acquired, excluding cash		$177,356

Liabilities assumed:
Deferred income taxes		$30,244
Accrued expenses	2,252
Accounts payable	1,889
Other liabilities	258
Total liabilities assumed		$34,643
Net assets acquired, excluding cash		$142,713

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 fiscal 2012 includes approximately $54.6 million and $3.6 million, respectively, from the acquisition of Switchcraft.

Other Acquisitions

In June 2014, the Company, through a subsidiary of its HEICO Flight Support Corp. subsidiary, acquired certain assets and liabilities of Quest Aviation Supply, Inc. (“Quest Aviation”). Quest Aviation is a niche supplier of parts to repair thrust reversers on various aircraft engines.

In October 2013, the Company acquired, through HEICO Electronic, all of the outstanding stock of Lucix Corporation ("Lucix") in a transaction carried out by means of a merger. Lucix is a leading designer and manufacturer of high performance, high reliability microwave modules, units, and integrated sub-systems for commercial and military satellites. The total consideration included an accrual of $7.0 million as of the acquisition date representing the fair value of contingent consideration the Company may have been obligated to pay had Lucix met certain earnings objectives during the last three months of the calendar year of acquisition. Additionally, the total consideration included an accrual of $13.7 million as of the acquisition date representing the fair value of contingent consideration the Company may be obligated to pay should Lucix meet certain earnings objectives during the subsequent two calendar years (2014 and 2015). As of the acquisition date, the maximum amount of contingent consideration that the Company could have been required to pay was $50.0 million in aggregate. See Note 7, Fair Value Measurements, for additional information regarding the Company’s contingent consideration obligation.

During fiscal 2013, the Company, through subsidiaries of HEICO Electronic, acquired certain product lines that will supplement their existing operations. The purchase price of these acquisitions was paid using cash provided by operating activities.

In October 2012, the Company, through HEICO Flight Support Corp., acquired 80.1% of the assets and assumed certain liabilities of Action Research Corporation (“Action Research”). Action Research is an FAA-Approved Repair Station that has developed unique proprietary repairs that extend the lives of certain engine and airframe components. The remaining 19.9% interest continues to be owned by an existing member of Action Research's management team. The purchase price of this acquisition was paid using cash provided by operating activities.

In August 2012, the Company, through HEICO Flight Support Corp., 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.

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.

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 total consideration included an accrual of approximately $10.8 million as of the acquisition date representing the fair value of contingent consideration in aggregate that the Company may be obligated to pay if Ramona Research meets certain earnings objectives during each of the first five years following the acquisition. As of the acquisition date, the maximum amount of contingent consideration that the Company could be required to pay is $14.6 million. See Note 7, Fair Value Measurements, for additional information regarding the Company's contingent consideration obligation.

Unless otherwise noted, the purchase price of each of the above referenced other acquisitions was paid in cash principally using proceeds from the Company's revolving credit facility and is not material or significant to the Company's consolidated financial statements.

The following table summarizes the allocation of the aggregate purchase price of the other acquisitions to the estimated fair values of the tangible and identifiable intangible assets acquired and liabilities and noncontrolling interests assumed (in thousands):



	Year ended October 31,
	2014		2013		2012
Assets Acquired:
Goodwill		$2,552		$68,095		$18,499
Identifiable intangible assets	3,400		39,843		21,831

Noncontrolling interests in consolidated subsidiaries		$—		$—		$3,918

Acquisitions, net of cash acquired		$6,759		$88,462		$33,950

The purchase price allocation of the Company's fiscal 2014 acquisition to the tangible and identifiable intangible assets acquired and liabilities assumed is preliminary until the Company obtains final information regarding their fair values. During fiscal 2014, the Company recorded certain immaterial measurement period adjustments to the purchase price allocation of its other fiscal 2013 acquisitions, which are reflected in the table above. The primary items that generated the goodwill recognized were the premiums paid by the Company for the future earnings potential of the businesses acquired and the value of their assembled workforces that do not qualify for separate recognition, which, in the case of CSI Aerospace and Action Research, benefit both the Company and the noncontrolling interest holders. Based on the factors comprising the goodwill recognized and consideration of an insignificant control premium, the fair value of the noncontrolling interest in Action Research was determined based on the consideration of the purchase price paid by the Company for its controlling ownership interest. The fair value of the noncontrolling interest in CSI Aerospace was determined based on the consideration of the purchase price paid by the Company for its controlling ownership interest adjusted for a lack of control that a market participant would consider when estimating the fair value of the noncontrolling interest.

The operating results of the Company’s fiscal 2014 acquisition were included in the Company’s results of operations from the effective acquisition date. The amount of net sales and earnings of the fiscal 2014 acquisition included in the Consolidated Statements of Operations is not material. Had the fiscal 2014 acquisition been consummated as of the beginning of fiscal 2013, net sales, net income from consolidated operations, net income attributable to HEICO, and basic and diluted net income per share attributable to HEICO shareholders on a pro forma basis for fiscal 2014 and 2013 would not have been materially different than the reported amounts.

Additional Purchase Consideration

During fiscal 2014, 2013 and 2012, the Company made additional purchase consideration payments of $2.0 million, $1.2 million and $5.5 million, respectively, pursuant to the terms of the purchase agreements related to certain recent acquisitions.

As part of the purchase agreements associated with certain acquisitions consummated prior to fiscal 2010, the Company was obligated to pay additional purchase consideration based on the acquired subsidiary meeting certain earnings objectives following the acquisition. For such acquisitions, the Company accrued an estimate of additional purchase consideration when the earnings objectives were met. During fiscal 2012, the Company, through HEICO Electronic, paid $15.1 million of such additional purchase consideration, of which $4.8 million was accrued as of October 31, 2011. The amounts paid in fiscal 2012 were based on a multiple of each applicable subsidiary's earnings relative to target and were not contingent upon the former shareholders of the respective acquired entity remaining employed by the Company or providing future services to the Company. Accordingly, the amounts paid were recorded as additional goodwill as they represented an additional cost of the respective entity. As of October 31, 2014 and 2013, the Company had no remaining obligation to pay additional purchase consideration for acquisitions consummated prior to fiscal 2010.

The amounts set forth above include tooling costs having a net book value of $6.0 million and $5.7 million as of October 31, 2014 and 2013, respectively. Amortization expense on capitalized tooling was $2.4 million, $2.2 million and $2.1 million in fiscal 2014, 2013 and 2012, respectively.

The amounts set forth above also include $4.6 million and $5.5 million of assets under capital leases as of October 31, 2014 and October 31, 2013, respectively. Accumulated depreciation associated with the assets under capital leases was $1.0 million and $1.1 million as of October 31, 2014 and October 31, 2013, respectively. See Note 5, Long-Term Debt, for additional information pertaining to these capital lease obligations.

Depreciation and amortization expense, exclusive of tooling, on property, plant and equipment was $17.1 million, $13.4 million and $11.6 million in fiscal 2014, 2013 and 2012, respectively.

Accrued Expenses and Other Current Liabilities



	As of October 31,

Accrued employee compensation and related payroll taxes		$52,480		$52,435
Deferred revenue	12,481		11,529
Accrued customer rebates and credits	10,924		14,787
Accrued additional purchase consideration	90		9,142
Other	16,603		17,841
Accrued expenses and other current liabilities		$92,578		$105,734

The total customer rebates and credits deducted within net sales in fiscal 2014, 2013 and 2012 was $8.3 million, $8.3 million and $2.8 million, respectively. The principal reason why the amount of customer rebates and credits deducted within net sales in fiscal 2012 is less than it was in fiscal 2014 and 2013 is fiscal 2012 reflected a reduction in the net sales volume of certain customers eligible for rebates as well as a reduction in the associated rebate percentages. The decrease in the amount of accrued customer rebates and credits principally reflects payments made during fiscal 2014 of certain amounts accrued over a two to three year period. The decrease in accrued additional purchase consideration pertains to a fiscal 2013 and a fiscal 2012 acquisition for which the underlying earnings objectives were not met. See Note 7, Fair Value Measurements, for additional information regarding the Company's contingent consideration obligations.

Other Long-Term Assets and Liabilities

The Company provides eligible employees, officers and directors of the Company the opportunity to voluntarily defer base salary, bonus payments, commissions, long-term incentive awards and directors fees, as applicable, on a pre-tax basis through the HEICO Corporation Leadership Compensation Plan (“LCP”), a nonqualified deferred compensation plan that conforms to Section 409A of the Internal Revenue Code. The Company matches 50% of the first 6% of base salary deferred by each participant. Director fees that would otherwise be payable in Company common stock may be deferred into the LCP, and, when distributable, are distributed in actual shares of Company common stock. The LCP does not provide for diversification of a director’s assets allocated to Company common stock. The deferred compensation obligation associated with Company common stock is recorded as a component of shareholders’ equity at cost and subsequent changes in fair value are not reflected in operations or shareholders’ equity of the Company. Further, while the Company has no obligation to do so, the LCP also provides the Company the opportunity to make discretionary contributions. The Company’s matching contributions and any discretionary contributions are subject to vesting and forfeiture provisions set forth in the LCP. Company contributions to the LCP charged to income in fiscal 2014, 2013 and 2012 totaled $5.3 million, $4.3 million and $3.8 million, respectively. The aggregate liabilities of the LCP were $65.0 million and $51.9 million as of October 31, 2014 and 2013, respectively, and are classified within other long-term liabilities in the Company’s Consolidated Balance Sheets. The assets of the LCP, totaling $65.9 million and $52.7 million as of October 31, 2014 and 2013, respectively, are classified within other assets and principally represent cash surrender values of life insurance policies that are held within an irrevocable trust that may be used to satisfy the obligations under the LCP.

Other long-term liabilities also includes deferred compensation of $5.5 million and $5.0 million as of October 31, 2014 and 2013, respectively, principally related to elective deferrals of salary and bonuses under a Company sponsored non-qualified deferred compensation plan available to selected employees. The Company makes no contributions to this plan. The assets of this plan, which equaled the deferred compensation liability as of October 31, 2014 and 2013, respectively, are held within an irrevocable trust and classified within other assets in the Company’s Consolidated Balance Sheets. Additional information regarding the assets of this deferred compensation plan and the LCP may be found in Note 7, Fair Value Measurements.

Adjustments to goodwill	—			27			27
Balances as of October 31, 2014		$282,407			$403,864			$686,271

The goodwill acquired during fiscal 2014 and 2013 relates to the acquisitions consummated in those respective years as described in Note 2, Acquisitions. Goodwill acquired represents the residual value after the allocation of the total consideration to the tangible and identifiable intangible assets acquired and liabilities assumed. The foreign currency translation adjustments reflect unrealized translation gains or losses on the goodwill recognized in connection with foreign subsidiaries. Foreign currency translation adjustments are included in other comprehensive income in the Company's Consolidated Statements of Comprehensive Income. The adjustments to goodwill during fiscal 2014 and 2013 represent immaterial measurement period adjustments to the purchase price allocations of certain fiscal 2013 and 2012 acquisitions, respectively. The Company estimates that all $3 million and approximately $5 million of the goodwill acquired in fiscal 2014 and 2013, respectively, is deductible for income tax purposes. Based on the annual test for goodwill impairment as of October 31, 2014, the Company determined there is no impairment of its goodwill and the fair value of each of the Company’s reporting units significantly exceeded their carrying value.

Identifiable intangible assets consist of (in thousands):

The decrease in the gross carrying amount of customer relationships, non-amortizing trade names and intellectual property primarily reflects impairment losses of $11.2 million, $1.9 million and $1.9 million, respectively, recognized during fiscal 2014. The impairment losses were due to reductions in the estimated future cash flows associated with such intangible assets within the ETG (see Note 7, Fair Value Measurements). The impairment losses pertaining to customer relationships and trade names were recorded as a component of selling, general and administrative expenses in the Company’s Consolidated Statement of Operations and the impairment loss pertaining to intellectual property was recorded as a component of cost of sales. The Company recognized certain intangible assets during fiscal 2014 in connection with an acquisition (see Note 2, Acquisitions). The amortization period of the customer relationships, intellectual property and amortizing trade names acquired is 8 years, 15 years, and 8 years, respectively.

Amortization expense related to intangible assets was $27.7 million, $20.6 million and $16.2 million in fiscal 2014, 2013 and 2012, respectively. Amortization expense for each of the next five fiscal years and thereafter is estimated to be $23.4 million in fiscal 2015, $21.8 million in fiscal 2016, $20.9 million in fiscal 2017, $19.1 million in fiscal 2018, $17.2 million in fiscal 2019 and $43.8 million thereafter.

Capital Lease Obligations

A subsidiary of HEICO Electronic is a party to a capital lease for a manufacturing facility and related property in France. The lease contains a bargain purchase option and has a twelve-year term, which began in fiscal 2011. Additionally, the subsidiary is a party to various capital leases, principally for manufacturing equipment, with lease terms ranging from approximately three to five years. The estimated future minimum lease payments of all capital leases for the next five fiscal years and thereafter are as follows (in thousands):

Revolving Credit Facility

In December 2011, the Company entered into a $670 million Revolving Credit Agreement (“Credit Facility”) with a bank syndicate. The Credit Facility may be used for working capital and general corporate needs of the Company, including capital expenditures and to finance acquisitions. In December 2012, the Company entered into an amendment to extend the maturity date of the Credit Facility by one year to December 2017. The Company also amended certain covenants contained within the Credit Facility agreement to accommodate payment of a special and extraordinary cash dividend paid in December 2012. See Note 8, Shareholders' Equity, for additional information.

In November 2013, the Company entered into an amendment to extend the maturity date of the Credit Facility by 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.

Advances under the Credit Facility accrue interest at the Company’s choice of the “Base Rate” or the London Interbank Offered Rate (“LIBOR”) plus applicable margins (based on the Company’s ratio of total funded debt to earnings before interest, taxes, depreciation and amortization, noncontrolling 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 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 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 Credit Facility may be accelerated upon an event of default, as such events are described in the Credit Facility. The Credit Facility is unsecured and contains covenants that restrict the amount of certain payments, including dividends, and 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 Credit Facility would become secured by the capital stock owned in substantially all of the Company’s subsidiaries.

As of October 31, 2014 and 2013, the weighted average interest rate on borrowings under the Credit Facility was 1.3%. The Credit Facility contains both financial and non-financial covenants. As of October 31, 2014, the Company was in compliance with all such covenants.

A reconciliation of the federal statutory income tax rate to the Company’s effective tax rate is as follows:



	Year ended October 31,
	2014		2013		2012
Federal statutory income tax rate	35.0	%	35.0	%	35.0	%
State taxes, net of federal income tax benefit	2.9		3.1		3.1
Nontaxable reduction in accrued contingent consideration	(3.4	)	—		—
Domestic production activities tax deduction	(1.6	)	(1.2	)	(1.3	)

Other, net	—		(.5	)	.9
Effective tax rate	30.1	%	31.1	%	33.8	%

The Company's effective tax rate in fiscal 2014 decreased to 30.1% from 31.1% in fiscal 2013. The decrease is principally attributed to the impact of a nontaxable reduction in accrued contingent consideration during fiscal 2014 associated with a fiscal 2013 acquisition acquired by means of a stock transaction. The aforementioned decrease in the effective tax rate was partially offset by lower U.S. federal research and development ("R&D") tax credits recognized in fiscal 2014 due to the expiration of the U.S. federal R&D tax credit in December 2013 compared to fiscal 2013 during which the retroactive extension of the U.S. federal R&D tax credit in the first quarter resulted in twenty-two months of U.S. federal R&D tax credits recognized that year. Additionally, the decrease in the effective rate was partially offset by higher tax-exempt unrealized gains in the cash surrender values of life insurance policies related to the HEICO Corporation Leadership Compensation Plan ("LCP") in fiscal 2013 compared to fiscal 2014.

The Company's effective tax rate in fiscal 2013 decreased to 31.1% from 33.8% in fiscal 2012. The decrease is partially due to higher research and development tax credits recognized in fiscal 2013 resulting from the retroactive extension of the U.S. federal R&D tax credit in January 2013 to cover a two-year period from January 1, 2012 to December 31, 2013. The decrease in the effective tax rate was also attributed to the benefit from higher tax-exempt unrealized gains in the cash surrender values of life insurance policies related to the LCP and a larger income tax deduction recognized for the special and extraordinary cash dividend paid in December 2012 to participants of the HEICO Savings and Investment Plan holding HEICO common stock.

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

Significant components of the Company’s deferred tax assets and liabilities are as follows (in thousands):



	As of October 31,
	2014			2013
Deferred tax assets:
Deferred compensation liability		$27,568			$22,242

Total deferred tax liabilities	(154,351		)	(162,351		)
Net deferred tax liability		($75,881	)		($93,655	)

The net deferred tax liability is classified in the Company’s Consolidated Balance Sheets as follows (in thousands):



	As of October 31,
	2014			2013
Current asset		$34,485			$33,036
Long-term asset	1,063			1,791
Long-term liability	(111,429		)	(128,482		)
Net deferred tax liability		($75,881	)		($93,655	)

The decrease in the Company's net deferred tax liability from $93.7 million as of October 31, 2013 to $75.9 million as of October 31, 2014 and the increase in the deferred income tax benefit from $5.8 million in fiscal 2013 to $16.7 million in fiscal 2014 is related to several items including the impact of impairment losses and amortization expense associated with intangible assets recognized in connection with fiscal 2013 acquisitions, the expiration of the bonus depreciation allowance on new property, plant and equipment acquired on or after January 1, 2014, and an increase in long-term deferred revenue. Additionally, the increase in the deferred tax asset related to the LCP resulting from additional compensation deferrals and higher earnings on deferred balances contributed to the decrease in the Company's net deferred tax liability.

As of October 31, 2014 and 2013, the Company’s liability for gross unrecognized tax benefits related to uncertain tax positions was $.9 million and $1.1 million, respectively, of which $.6 million and $.8 million, respectively, would decrease the Company’s income tax expense and effective income tax rate if the tax benefits were recognized. A reconciliation of the activity related to the liability for gross unrecognized tax benefits during the fiscal years ended October 31, 2014 and 2013 is as follows (in thousands):



	Year ended October 31,
	2014			2013
Balances as of beginning of year		$1,072			$2,527
Increases related to prior year tax positions	10			58
Decreases related to prior year tax positions	—			(967		)
Increases related to current year tax positions	138			108
Settlements	(22		)	(570		)
Lapse of statutes of limitations	(319		)	(84		)
Balances as of end of year		$879			$1,072

The decreases related to settlements and prior year tax positions recognized in fiscal 2013 pertain to state income tax positions regarding nexus and state apportionment, respectively, which were originally recognized in fiscal 2012 and resolved through the filing of state income tax returns in fiscal 2013 and the finalization of a state tax audit, respectively. The Company does not expect the total amount of unrecognized tax benefits to materially change in the next twelve months.

The Company's net liability for unrecognized tax benefits was $.8 million as of October 31, 2014, including $.3 million of interest and penalties and net of $.4 million in deferred tax assets. The Company’s net liability for unrecognized tax benefits was $1.0 million as of October 31, 2013, including $.3 million of interest and penalties and net of $.4 million in deferred tax assets. The Company recognized interest and penalties of ($.1) million, ($.2) million and $.4 million in fiscal 2014, 2013 and 2012, respectively, related to unrecognized tax benefits.

The Company files income tax returns in the United States (“U.S.”) federal jurisdiction and in multiple state jurisdictions. The Company is also subject to income taxes in certain jurisdictions outside the U.S., none of which are individually material to the accompanying consolidated financial statements. Generally, the Company is no longer subject to U.S. federal, state or foreign examinations by tax authorities for years prior to fiscal 2010.

The Company maintains two non-qualified deferred compensation plans. The assets of 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 valued using a market approach. Certain other assets of the LCP represent investments in money market funds that are classified within Level 1. 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 Consolidated Balance Sheets.

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 had the acquired entity 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 each of the next 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 ("SG&A") in the Company's Consolidated Statement of Operations in the first quarter of fiscal 2014. The estimated fair value of the contingent consideration for the calendar 2014 and 2015 earnings period was $1.2 million as of October 31, 2014 compared to $13.7 million as of October 31, 2013. The $12.5 million decrease in the fair value of the contingent consideration is principally attributed to revised earnings estimates that reflect less favorable projected market conditions for certain of the space products it produces and was recorded as a reduction to SG&A expenses. Additionally, the aforementioned conditions resulted in the Company concluding it had a triggering event requiring assessment of impairment of the subsidiary's intangible assets during fiscal 2014. Please see below for further information pertaining to the measurement and recognition of impairment losses associated with the intangible assets of this subsidiary.

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 $10.6 million in aggregate should the acquired entity meet certain earnings objectives during each of the next three years following the second anniversary date of the acquisition. The $8.6 million estimated fair value of the contingent consideration as of October 31, 2013 was recorded as a reduction to SG&A expenses in the Company's Consolidated Statement of Operations during fiscal 2014. The decrease in the fair value of the contingent consideration is principally attributed to revised earnings estimates that reflect less favorable market conditions for certain of the defense products it produces. Additionally, the aforementioned conditions resulted in the Company concluding it had a triggering event requiring assessment of impairment of the subsidiary's intangible assets during fiscal 2014. Please see below for further information pertaining to the measurement and recognition of impairment losses associated with the intangible assets of this subsidiary.

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 was 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 consolidated statements of operations.

The Level 3 inputs used to derive the estimated fair values of the contingent consideration as of October 31, 2014 are as follows:



	Fiscal 2013 Acquisition	Fiscal 2012 Acquisition
Compound annual revenue growth rate range	(7%) - 20%	(8%) - 26%
Weighted average discount rate	2.6%	3.0%

Changes in the Company’s assets and liabilities measured at fair value on a recurring basis using unobservable inputs (Level 3) for the fiscal years ended October 31, 2014 and 2013 are as follows (in thousands):



	Assets			Liabilities
Balances as of October 31, 2012		$538			$10,897
Contingent consideration related to acquisition	—			20,654
Payment of contingent consideration	—			(601		)
Decrease in accrued contingent consideration	—			(1,640		)
Total realized gains	48			—
Sales	(586		)	—
Balances as of October 31, 2013	—			29,310
Decrease in accrued contingent consideration	—			(28,126		)
Balances as of October 31, 2014		$—			$1,184

The Company did not have any transfers between Level 1 and Level 2 fair value measurements during fiscal 2014 and 2013.

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 October 31, 2014 due to the relatively short maturity of the respective instruments. The carrying value of long-term debt approximates fair value due to its variable interest rates.

During fiscal 2014, certain customer relationships, non-amortizing trade names and intellectual property within the ETG were measured at fair value on a nonrecurring basis, resulting in the recognition of impairment losses aggregating $15.0 million.

The fair values of the Company’s nonfinancial assets and liabilities that were measured at fair value on a nonrecurring basis, which are classified within Level 3, and the related impairment losses recognized in fiscal 2014 are as follows (in thousands):



	Carrying Amount		Impairment Loss			Fair Value (Level 3)
Assets:
Customer relationships		$19,366		($11,200	)		$8,166
Non-amortizing trade names	10,000		(1,900		)	8,100
Intellectual property	2,302		(1,900		)	402
Impairment of intangible assets				($15,000	)

The fair values of such customer relationships, non-amortizing trade names and intellectual property were determined using variations of the income approach which apply an asset-specific discount rate to a forecast of asset-specific cash flows. These methods utilize certain significant unobservable inputs categorized as Level 3. The Level 3 inputs used to derive the estimated fair values of the customer relationships, non-amortizing trade names and intellectual property during fiscal 2014 are as follows:



	Customer Relationships	Non-Amortizing Trade Names	Intellectual Property
Valuation method	Excess Earnings	Relief from Royalty	Relief from Royalty
Discount rate	15.0% - 19.0%	14.0% - 18.0%	19.0%
Annual attrition rate	25.0% - 30.0%	N/A	20.0%
Royalty rate	N/A	1.0% - 2.5%	6.0%

SHAREHOLDERS' EQUITY	12 Months Ended
SHAREHOLDERS' EQUITY	Oct. 31, 2014
Stockholders' Equity Note [Abstract]
Stockholders' Equity Note Disclosure [Text Block]	SHAREHOLDERS’ EQUITY Preferred Stock Purchase Rights Plan The Company’s Board of Directors adopted, as of November 2, 2003, a Shareholder Rights Agreement (the “2003 Plan”). Pursuant to the 2003 Plan, the Board declared a dividend of one preferred share purchase right for each outstanding share of Common Stock and Class A Common Stock (with the preferred share purchase rights collectively as the “Rights”). The Rights trade with the common stock and are not exercisable or transferable apart from the Common Stock and Class A Common Stock until after a person or group either acquires 15% or more of the outstanding common stock or commences or announces an intention to commence a tender offer for 15% or more of the outstanding common stock. The Rights expired on November 2, 2013. The Rights had certain anti-takeover effects and, therefore, would have caused substantial dilution to a person or group who attempted to acquire the Company on terms not approved by the Company’s Board of Directors or who acquired 15% or more of the outstanding common stock without approval of the Company’s Board of Directors. The Rights would not have interfered with any merger or other business combination that was approved by the Board since they may have been redeemed by the Company at $.01 per Right at any time until the close of business on the tenth day after a person or group had obtained beneficial ownership of 15% or more of the outstanding common stock or until a person commenced or announced an intention to commence a tender offer for 15% or more of the outstanding common stock. The 2003 Plan also contained a provision to help ensure a potential acquirer pays all shareholders a fair price for the Company. Common Stock and Class A Common Stock Each share of Common Stock is entitled to one vote per share. Each share of Class A Common Stock is entitled to a 1/10 vote per share. Holders of the Company’s Common Stock and Class A Common Stock are entitled to receive when, as and if declared by the Board of Directors, dividends and other distributions payable in cash, property, stock or otherwise. In the event of liquidation, after payment of debts and other liabilities of the Company, the remaining assets of the Company will be distributable ratably among the holders of all classes of common stock. Stock Splits In September 2013 and 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 splits were effected as of October 23, 2013 and April 25, 2012, respectively, in the form of a 25% stock dividend distributed to shareholders of record as of October 11, 2013 and April 13, 2012, respectively. All applicable share and per share information has been adjusted retrospectively to give effect to the 5-for-4 stock splits. Share Repurchases In 1990, the Company's Board of Directors authorized a share repurchase program, which allows the Company to repurchase Company shares in the open market or in privately negotiated transactions at the Company's discretion, subject to certain restrictions included in the Company's revolving credit agreement. As of October 31, 2014, the maximum number of shares that may yet be purchased under this program was 2,501,813 of either or both of the Company's Class A Common Stock and the Company's Common Stock. The repurchase program does not have a fixed termination date. During fiscal 2014, 2013 and 2012, the Company did not repurchase any shares of Company common stock under this program. During fiscal 2014, the Company repurchased an aggregate 6,833 shares of Class A Common Stock at a total cost of approximately $.3 million. The shares purchased represent shares tendered as payment of employee withholding taxes due upon the issuance of a share-based award. During fiscal 2013, the Company repurchased an aggregate 36,354 shares of Common Stock at a total cost of $1.3 million and an aggregate 39,965 shares of Class A Common Stock at a total cost of $1.1 million. During fiscal 2012, the Company repurchased an aggregate 3,808 shares of Common Stock at a total cost of approximately $.1 million and an aggregate 7,510 shares of Class A Common Stock at a total cost of $.2 million. The transactions in fiscal 2013 and 2012 occurred as settlement for employee taxes due pertaining to exercises of non-qualified stock options. The shares purchased in fiscal 2014, 2013 and 2012 did not impact the number of shares authorized for future purchase under the Company’s share repurchase program and are reflected as redemptions of common stock related to share-based compensation in the Company's Consolidated Statements of Shareholders' Equity and the Company's Consolidated Statements of Cash Flows. Special and Extraordinary Cash Dividends In January 2014, the Company paid a special and extraordinary $.35 per share cash dividend on both classes of HEICO's common stock as well as its regular semi-annual $.06 per share cash dividend. In December 2012, the Company paid a special and extraordinary $1.712 per share cash dividend on both classes of HEICO's common stock as well as a regular semi-annual $.048 per share cash dividend that was accelerated from January 2013. The dividends, which aggregated $27.2 million in fiscal 2014 and $116.6 million in fiscal 2013, were principally funded from borrowings under the Company's revolving credit facility. Noncontrolling Interests Consistent with the Company's past practice of increasing its ownership in certain non-wholly-owned subsidiaries, on February 14, 2014, HEICO Corporation acquired the 20% noncontrolling interest held by LHT in four of the Company's existing subsidiaries principally operating in the specialty products and distribution businesses within HEICO Aerospace (the “Transaction”). Pursuant to the Transaction, HEICO Aerospace paid dividends proportional to the ownership (80%/20%) to HEICO and LHT, and HEICO transferred the businesses to HEICO Flight Support Corp. HEICO did not record any gain or loss in connection with the Transaction. LHT’s dividend of $67.4 million was paid in cash, principally using proceeds from the Company’s revolving credit facility. LHT remains a 20% owner in HEICO Aerospace, a leading producer of PMA parts and component repair and overhaul services. During fiscal 2014, the Put Right held by the noncontrolling interest holders in one of the Company's subsidiaries expired, resulting in a reclassification of the Redemption Amount from redeemable noncontrolling interests (temporary equity) to noncontrolling interests (permanent equity). See Note 11, Redeemable Noncontrolling Interests, for additional information.

- Definition

The entire disclosure for shareholders' equity comprised of portions attributable to the parent entity and noncontrolling interest, including other comprehensive income. Includes, but is not limited to, balances of common stock, preferred stock, additional paid-in capital, other capital and retained earnings, accumulated balance for each classification of other comprehensive income and amount of comprehensive income.

SHARE-BASED COMPENSATION

12 Months Ended

Oct. 31, 2014

Disclosure of Compensation Related Costs, Share-based Payments [Abstract]

Disclosure of Compensation Related Costs, Share-based Payments [Text Block]

SHARE-BASED COMPENSATION

The Company currently maintains one share-based compensation plan, the HEICO Corporation 2012 Incentive Compensation Plan (“2012 Plan”), under which it may grant various forms of share-based compensation awards including, but not limited to, stock options, restricted stock, restricted stock awards and stock appreciation rights. The 2012 Plan became effective in March 2012, the same time the Company's 2002 Stock Option Plan (“2002 Plan”) and its remaining 2.0 million unissued shares expired. Also, in March 2012, the Company made a decision to no longer issue options under its Non-Qualified Stock Option Plan (“NQSOP”) under which less than .1 million remaining unissued shares were cancelled. Options outstanding under the 2002 Plan and NQSOP may be exercised pursuant to their terms. The total number of shares approved by the shareholders of the Company for the 2012 Plan is 2.7 million plus any options outstanding under the 2002 Plan and NQSOP as of the 2012 Plan's effective date and that are subsequently forfeited or expire. A total of 4.9 million shares of the Company's common stock are reserved for issuance to employees, directors, officers and consultants as of October 31, 2014, including 3.3 million shares currently under option and 1.6 million shares available for future grants.

Stock options granted pursuant to the 2012 Plan may be designated as Common Stock and/or Class A Common Stock in such proportions as shall be determined by the Board of Directors or the Stock Option Plan Committee at its sole discretion. The exercise price per share of a stock option granted under the 2012 Plan may not be less than the fair market value of the designated class of Company common stock as of the date of grant and stock option grants vest ratably over a period specified as of the date of grant (generally five years) and expire ten years after the date of grant. Options issued under the 2012 Plan may be designated as incentive stock options or non-qualified stock options, but only employees are eligible to receive incentive stock options. The 2012 Plan will terminate no later than the tenth anniversary of its effective date.

Information concerning share-based activity for each of the last three fiscal years ended October 31 is as follows (in thousands, except per share data):

Net income attributable to HEICO for the fiscal years ended October 31, 2014, 2013 and 2012 includes compensation expense of $6.2 million, $5.1 million and $3.9 million, respectively, and an income tax benefit of $2.4 million, $2.0 million and $1.5 million, respectively, related to the Company’s stock options. Substantially all of the stock option compensation expense was recorded as a component of selling, general and administrative expenses in the Company’s Consolidated Statements of Operations. As of October 31, 2014, there was $14.5 million of pre-tax unrecognized compensation expense related to nonvested stock options, which is expected to be recognized over a weighted average period of approximately 3.2 years. The total fair value of stock options that vested in fiscal 2014, 2013 and 2012 was $5.9 million, $4.5 million and $3.6 million, respectively. If there were a change in control of the Company, all of the unvested options outstanding as of October 31, 2014 would become immediately exercisable.

For the fiscal years ended October 31, 2014, 2013 and 2012, the excess tax benefit resulting from tax deductions in excess of the cumulative compensation cost recognized for stock options exercised was $.1 million, $5.1 million and $12.1 million, respectively, and is presented as a financing activity in the Company’s Consolidated Statements of Cash Flows.

The fair value of each stock option grant was estimated on the date of grant using the Black-Scholes option-pricing model based on the following weighted average assumptions for the fiscal years ended October 31, 2014, 2013 and 2012:



	2014		2013				2012
	Class A Common Stock		Common Stock		Class A Common Stock		Class A Common Stock
Expected stock price volatility	38.04	%	39.94	%	38.40	%	40.11	%

EMPLOYEE RETIREMENT PLANS

The HEICO Savings and Investment Plan (the “401(k) Plan”) is a qualified defined contribution retirement plan under which eligible employees of the Company and its participating subsidiaries may make Elective Deferral Contributions up to the limitations set forth in Section 402(g) of the Internal Revenue Code. The Company generally makes a 25% or 50% Employer Matching Contribution, as determined by the Board of Directors, based on a participant’s Elective Deferral Contribution up to 6% of the participant’s Compensation for the Elective Deferral Contribution period. The 401(k) Plan also provides that the Company may make additional Employer Contributions. Employer Contributions may be contributed in the form of the Company’s common stock or cash, as determined by the Company. Employer Contributions awarded in the form of Company common stock are valued based on the fair value of the underlying shares as of the effective date of contribution. Employer Contributions may be diversified by a participant into any of the participant-directed investment options of the 401(k) Plan; however, Employee Contributions may not be invested in Company common stock.

Participants receive 100% vesting of Employee Contributions and cash dividends received on Company common stock. Vesting in Employer Contributions is based on a participant’s number of years of vesting service. Employer Contributions to the 401(k) Plan charged to income in fiscal 2014, 2013 and 2012 totaled $6.3 million, $3.2 million and $3.0 million, respectively, and were made through the issuance of new shares of Company common stock and the use of forfeited shares within the 401(k) Plan.

In fiscal 2012, the Company's Board of Directors authorized 187,500 shares of the Company's Common Stock and 187,500 shares of the Company's Class A Common Stock be reversed and made available for issuance under the 401(k) Plan. Information concerning share-based activity pertaining to the 401(k) Plan for each of the last three fiscal years ended October 31 is as follows (in thousands):

The $2.5 million and $1.8 million difference between the projected benefit obligation and fair value of plan assets as of October 31, 2014 and October 31, 2013, respectively, are included in other long-term liabilities within the Company's Consolidated Balance Sheets. Additionally, the Plan experienced a $.9 million net actuarial loss and $1.0 million net actuarial gain during fiscal 2014 and 2013, respectively, that were recognized in other comprehensive income (where they are reported net of ($.3) million and $.4 million of tax, respectively). As of October 31, 2014, $.1 million represents the total actuarial gain in accumulated other comprehensive income that have yet to be recognized as a component of net periodic pension income. The Company does not expect to recognize any of the amount within accumulated other comprehensive income as of October 31, 2014 as a component of net periodic pension income during fiscal 2015.

Weighted average assumptions used to determine the projected benefit obligation as of October 31, 2014 and October 31, 2013 and net pension income for the fiscal year ended October 31, 2014 and October 31, 2013 are as follows:



	Projected Benefit Obligation				Net Pension Income
	2014		2013		2014		2013
Discount rate	4.20	%	4.79	%	4.79	%	3.99	%
Expected return on plan assets	N/A		N/A		6.75	%	6.75	%

The discount rate was determined using the results of a bond yield curve model based on a portfolio of high-quality bonds matching expected Plan benefit payments. The expected return on Plan assets was based upon the current and expected target asset allocation and investment return estimates for the Plan's equity and fixed income securities. In establishing this assumption, the Company considers many factors including both the historical rate of return and projected inflation-adjusted real rate of return on the Plan's various asset classes and the expected working lifetime for Plan participants.

Components of net pension income for the fiscal years ended October 31, 2014 and October 31, 2013 that were recorded within the Company's Consolidated Statements of Operations are as follows (in thousands):



	Year ended October 31,
	2014		2013
Expected return on plan assets		$739		$320
Interest cost	610		236
Net pension income		$129		$84

The Company anticipates making contributions of $.1 million to the Plan during fiscal 2015. Estimated future benefit payments to be made during each of the next five fiscal years and in aggregate during the succeeding five fiscal years are as follows (in thousands):

Equity securities consist of investments in common stocks, mutual funds and exchange traded funds. Fixed income securities consist of investments in mutual funds.

The Plan's actual and targeted asset allocations by investment category are as follows:



	As of October 31,
	2014				2013
	Actual		Target		Actual		Target

REDEEMABLE NONCONTROLLING INTERESTS	12 Months Ended
REDEEMABLE NONCONTROLLING INTERESTS	Oct. 31, 2014
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 2022. The Put Rights, all of which relate either to common shares or membership interests in limited liability companies, provide that the cash consideration to be paid for their equity interests (the “Redemption Amount”) be at fair value or at a formula that management intended to reasonably approximate fair value based solely on a multiple of future earnings over a measurement period. As of October 31, 2014, management’s estimate of the aggregate Redemption Amount of all Put Rights that the Company would be required to pay is approximately $40.0 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 actual or earliest exercise date, the measurement period and any applicable fair value adjustments. The portion of the estimated Redemption Amount as of October 31, 2014 redeemable at fair value is approximately $27.7 million and the portion redeemable based solely on a multiple of future earnings is approximately $12.3 million. A summary of the put and call rights associated with the redeemable noncontrolling interests in certain of the Company’s subsidiaries and a description of any transactions involving redeemable noncontrolling interests during fiscal 2014, 2013 and 2012 is as follows: The Company acquired an 80.1% interest in a subsidiary through the ETG in fiscal 2004. As part of the purchase agreement, the noncontrolling interest holders had the right to cause the Company to purchase their interests over a five-year period. During fiscal 2014, the noncontrolling interest holders' Put Right expired, resulting in a reclassification of the Redemption Amount from redeemable noncontrolling interests (temporary equity) to noncontrolling interests (permanent equity). Furthermore, the Company has the right to purchase the noncontrolling interests over a five-year period beginning in fiscal 2015, or sooner under certain conditions. Pursuant to the purchase agreement related to the acquisition of an 85% interest in a subsidiary by the ETG in fiscal 2005, the noncontrolling interest holders have the right to cause the Company to purchase their interests over a four-year period beginning in fiscal 2007 or thereafter. Certain noncontrolling interest holders exercised their option during prior years, which resulted in the Company increasing its ownership interest in the subsidiary to 95.9% effective fiscal 2011. Pursuant to the purchase agreement related to the acquisition of a 51% interest in a subsidiary by the FSG in fiscal 2006, certain noncontrolling interest holders exercised their option to cause the Company to purchase an aggregate 29% interest, which was completed in fiscal 2011. During fiscal 2012, the remaining noncontrolling interest holder exercised their option to cause the Company to purchase the remaining 20% interest, of which 6.7% was acquired effective February 2012 and 13.3% was acquired effective December 2012. During fiscal 2014, the Company paid a purchase price adjustment for the portion of the redeemable noncontrolling interests acquired in December 2012 that was based on the acquired entity's actual fiscal 2013 earnings. The Company acquired an 80.1% interest in a subsidiary through the FSG in fiscal 2006. As part of the purchase agreement, the Company has the right to purchase the noncontrolling interests over a four-year period and the noncontrolling interest holders have the right to cause the Company to purchase the same equity interests over the same period. The Company acquired an 80.1% interest in a subsidiary through the FSG in fiscal 2008 and acquired an additional 2.2% interest in fiscal 2010, which increased the Company's ownership interest to 82.3%. Pursuant to the original purchase agreement as amended in fiscal 2012, the Company has the right to purchase the remaining noncontrolling interests over a five-year period beginning in fiscal 2016, or sooner under certain conditions, and the noncontrolling interest holders have the right to cause the Company to purchase the same equity interests over the same period. The Company acquired an 82.5% interest in a subsidiary through the ETG in fiscal 2009. As part of the purchase agreement, the Company has the right to purchase the noncontrolling interests in a lump sum transaction and the noncontrolling interest holder has the right to cause the Company to purchase the same equity interests over the same period. The Company acquired an 80.1% interest in a subsidiary through the FSG in fiscal 2011. As part of the purchase agreement, the Company has the right to purchase the noncontrolling interests over a two-year period beginning in fiscal 2015, or sooner under certain conditions, and the noncontrolling interest holders have the right to cause the Company to purchase the same equity interests over the same period. During fiscal 2012, one of the subsidiaries of the ETG formed a new subsidiary which acquired certain assets and liabilities of two businesses in exchange for shares aggregating 22% of its equity interest, valued at $.4 million. The noncontrolling interest holders have the right to cause the Company to purchase their equity interests over a two-year period beginning in fiscal 2017. The Company acquired an 84% interest in a subsidiary through the FSG in fiscal 2012. As part of the purchase agreement, the Company has the right to purchase the noncontrolling interests over a four-year period beginning in fiscal 2018, or sooner under certain conditions, and the noncontrolling interest holders have the right to cause the Company to purchase the same equity interests over the same period. The Company acquired an 80.1% interest in a subsidiary through the FSG in fiscal 2012. As part of the purchase agreement, the Company has the right to purchase the noncontrolling interests over a four-year period beginning in fiscal 2019, or sooner under certain conditions, and the noncontrolling interest holder has the right to cause the Company to purchase the same equity interests over the same period. The purchase prices of the redeemable noncontrolling interests acquired in fiscal 2014 and 2012 were paid using cash provided by operating activities. The purchase price of the redeemable noncontrolling interests acquired in fiscal 2013 was paid using proceeds from the Company's revolving credit facility. The aggregate cost of the redeemable noncontrolling interests acquired was $1.2 million, $16.6 million and $7.6 million in fiscal 2014, 2013 and 2012, respectively.

During the fourth quarter of fiscal 2014, the Company recorded a reduction in accrued contingent consideration related to a fiscal 2012 acquisition that was partially offset by impairment losses related to the write-down of certain intangible assets at the acquired business resulting in an increase in net income attributable to HEICO of approximately $1.7 million, or $.03 per basic and diluted share.

During the third quarter of fiscal 2014, the Company recorded a reduction in accrued contingent consideration related to a fiscal 2013 acquisition that was partially offset by impairment losses related to the write-down of certain intangible assets and lower than expected operating income at the acquired business resulting in an increase in net income attributable to HEICO of approximately $3.4 million, or $.05 per basic and diluted share.

During the first quarter of fiscal 2014, the Company recorded a reduction in accrued contingent consideration related to a fiscal 2013 acquisition that was partially offset by lower than expected operating income at the acquired business resulting in an increase in net income attributable to HEICO of approximately $2.6 million, or $.04 per basic and diluted share.

During the third quarter of fiscal 2013, the Company filed its fiscal 2012 U.S. federal and state tax returns. As a result, the Company recognized a benefit, which increased net income attributable to HEICO by approximately $.8 million, or $.01 per basic and diluted share, net of expenses, from higher research and development tax credits.

During the first quarter of fiscal 2013, the Company recognized an income tax credit for qualified research and development activities for the last ten months of fiscal 2012 upon the retroactive extension of the U.S. federal research and development tax credit in January 2013 to cover a two-year period from January 1, 2012 to December 31, 2013. The tax credit, net of expenses, increased net income attributable to HEICO by $1.0 million, or $.01 per basic and diluted share.

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