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, the technical services subsidiary of Lufthansa German Airlines. In addition, HEICO Aerospace consolidates three subsidiaries which are 80.1%, 80.1% and 82.3% owned, respectively, and a joint venture, which is 84% owned. Also, HEICO Flight Support Corp. consolidates two subsidiaries which are 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 12, Redeemable Noncontrolling Interests. All significant intercompany balances and transactions are eliminated.

Stock Splits

In September 2013, March 2012 and March 2011, 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, April 25, 2012 and April 26, 2011, respectively, in the form of a 25% stock dividend distributed to shareholders of record as of October 11, 2013, April 13, 2012 and April 15, 2011, 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 2013, 2012 or 2011.

For contingent consideration arrangements associated with acquisitions consummated during or after fiscal 2010, a liability is recognized at fair value as of the acquisition date with subsequent fair value adjustments recorded in operations. For contingent consideration arrangements associated with acquisitions consummated prior to fiscal 2010, a liability and additional goodwill was recognized only when the earnings objectives were met. Information regarding additional contingent purchase consideration related to acquisitions both prior and subsequent to fiscal 2010 may be found in Note 2, Acquisitions.

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

Amortization expense of intellectual property, licenses and patents is recorded as a component of cost of sales, and amortization expense of customer relationships, non-compete agreements and trade names is recorded as a component of selling, general and administrative expenses in the Company’s Consolidated Statement of Operations. The Company tests each non-amortizing intangible asset for impairment annually as of October 31, or more frequently if events or changes in circumstances indicate that the asset might be impaired. To derive the fair value of its trade names, the Company utilizes an income approach, 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 Statement of Operations.

Derivative Instruments

From time to time, the Company utilizes certain derivative instruments (e.g. foreign currency forward contracts and interest rate swap agreements) to hedge the variability of foreign currency exchange rates and the expected future cash flows of certain transactions. Changes in the fair value of derivative instruments are recognized immediately in earnings, unless the derivative is designated as a hedge and qualifies for hedge accounting. There are three hedging relationships where a derivative (hedging instrument) may qualify for hedge accounting: (1) a hedge of the change in fair value of a recognized asset or liability or firm commitment (fair value hedge), (2) a hedge of the variability in cash flows from forecasted transactions (cash flow hedge), and (3) a hedge of the variability caused by changes in foreign currency exchange rates (foreign currency hedge).

Under hedge accounting, recognition of derivative gains and losses can be matched in the same period with that of the hedged exposure and thereby minimize earnings volatility. In order for a derivative to qualify for hedge accounting, the derivative must be formally designated as a fair value, cash flow, or a foreign currency hedge by documenting the relationship between the derivative and the hedged item. Additionally, the hedge relationship must be expected to be highly effective at offsetting changes in either the fair value or cash flows of the hedged item at both inception and on an ongoing basis. For a derivative instrument that qualifies for hedge accounting, the effective portion of changes in fair value of the derivative is deferred and recorded as a component of other comprehensive income until the hedged transaction occurs and is recognized in earnings. All other portions of changes in fair value of the derivative are recognized in earnings immediately. If the derivative does not qualify for hedge accounting, the Company considers the transaction to be an “economic hedge” and changes in the fair value of the derivative asset or liability are recognized immediately in earnings.

During fiscal 2012 and 2011, the Company entered into foreign currency forward contracts to mitigate foreign exchange risk of certain transactions. The impact of these forward contracts did not have a material effect on the Company’s results of operations, financial position or cash flows in fiscal 2012 or 2011. The Company did not utilize any derivative investments in fiscal 2013.

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 the acquisition of Reinhold Industries, Inc. (“Reinhold”) (see Note 2, Acquisitions), the Company assumed Reinhold's 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 Sheet. 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, 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 1% in fiscal 2013, 2012 and 2011. 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 2013, 2012 or 2011.

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.

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

Income Taxes

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

The Company accounts for uncertainty in income taxes and evaluates tax positions utilizing a two-step process. The first step is to determine whether it is more-likely-than-not that a tax position will be sustained upon examination based on the technical merits of the position. The second step is to measure the benefit to be recorded from tax positions that meet the more-likely-than-not recognition threshold by determining the largest amount of tax benefit that is greater than 50 percent likely of being realized upon ultimate settlement and recognizing that amount in the financial statements. 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 12, Redeemable Noncontrolling Interests, the holders of equity interests in certain of the Company’s subsidiaries have rights (“Put Rights”) that require the Company to provide cash consideration for their equity interests (the “Redemption Amount”) at fair value or at a formula that management intended to reasonably approximate fair value based solely on a multiple of future earnings over a measurement period. The Put Rights are embedded in the shares owned by the noncontrolling interest holders and are not freestanding. 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 13, Net Income per Share Attributable to HEICO Shareholders).

Foreign Currency Translation

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

Contingencies

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

New Accounting Pronouncements

In June 2011, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2011-05, “Presentation of Comprehensive Income,” which requires the presentation of total comprehensive income, the components of net income and the components of other comprehensive income in either a single continuous statement of comprehensive income or in two separate, but consecutive statements. ASU 2011-05 eliminates the option to present other comprehensive income and its components in the statement of shareholders’ equity. The Company adopted ASU 2011-05 in the first quarter of fiscal 2013 and elected to make the presentation in two separate, but consecutive statements, which had no impact on the Company's consolidated results of operations, financial position or cash flows.

In September 2011, the FASB issued ASU 2011-08, “Testing Goodwill for Impairment,” which is intended to reduce the complexity and cost of performing a quantitative test for impairment of goodwill by permitting an entity the option to perform a qualitative evaluation about the likelihood of goodwill impairment in order to determine whether it should calculate the fair value of a reporting unit. The update also improves previous guidance by expanding upon the examples of events and circumstances that an entity should consider between annual impairment tests in determining whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount. The Company adopted ASU 2011-08 in the fourth quarter of fiscal 2013 but elected to perform a quantitative test when performing its fiscal 2013 impairment test. The adoption of this guidance had no impact on the Company's consolidated results of operations, financial position or cash flows.

In February 2013, the FASB issued 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. ASU 2013-02 is effective prospectively for fiscal years and interim periods within those fiscal years beginning after December 15, 2012, or in fiscal 2014 for HEICO. Early adoption is permitted. The adoption of this guidance is not expected to have a material 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.

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	2,832
Total assets acquired, excluding cash		$173,333

Liabilities assumed:
Deferred income taxes		$25,631
Accrued expenses	6,994
Accounts payable	2,923
Defined benefit pension plan obligation, net	2,865
Accrued additional purchase consideration	1,557
Other liabilities	390
Total liabilities assumed		$40,360
Net assets acquired, excluding cash		$132,973

The allocation of the purchase price to the tangible and identifiable assets acquired and liabilities assumed is preliminary until the Company obtains final information regarding their fair values. However, the Company does not expect any adjustments to such allocation to be material to the Company's consolidated financial statements. 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 the year ended October 31, 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 the year ended October 31, 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.

The following table presents unaudited pro forma financial information for fiscal 2011 as if the acquisition of Switchcraft had occurred as of November 1, 2010 (in thousands):



	Year ended
	October 31, 2011
Net sales		$824,767
Net income from consolidated operations		$100,842
Net income attributable to HEICO		$78,209
Net income per share attributable to HEICO shareholders:
Basic		$1.20
Diluted		$1.18

The pro forma financial information is presented for comparative purposes only and is not necessarily indicative of the results of operations that actually would have been achieved if the acquisition had taken place as of November 1, 2010. The unaudited pro forma financial information includes adjustments to historical amounts such as additional amortization expense related to intangible assets acquired, increased interest expense associated with borrowings to finance the acquisition and inventory purchase accounting adjustments charged to cost of sales as the inventory is sold. Had the acquisition been consummated as of November 1, 2010, net sales, net income from consolidated operations, net income attributable to HEICO, and basic and diluted net income per share attributable to HEICO shareholders on a pro forma basis for fiscal 2012 would not have been materially different than the reported amounts.

Other Acquisitions

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 includes an accrual of approximately $20.7 million as of the acquisition date representing the fair value of contingent consideration in aggregate that the Company may be obligated to pay should Lucix meet certain earnings objectives during the last three months of the calendar year of acquisition and during the subsequent two calendar years (2014 and 2015). The maximum amount of contingent consideration that the Company could be required to pay is $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 includes 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.

In September 2011, the Company, through HEICO Electronic, acquired all of the outstanding capital stock of 3D Plus SA (“3D Plus”). 3D Plus is a leading designer and manufacturer of three-dimensional microelectronic and stacked memory products used predominately in satellites and also utilized in medical equipment.

In December 2010, the Company, through HEICO Aerospace, acquired 80.1% of the assets and assumed certain liabilities of Blue Aerospace LLC ("Blue Aerospace"). Blue Aerospace is a supplier, distributor, and integrator of military aircraft parts and support services primarily to foreign military organizations allied with the United States. The remaining 19.9% interest continues to be owned by certain members of Blue Aerospace’s management team.

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,
	2013		2012		2011
Assets Acquired:
Goodwill		$68,068		$18,499		$49,575
Identifiable intangible assets	39,843		21,831		40,187

Noncontrolling interests in consolidated subsidiaries		$—		$3,918		$5,921

Acquisitions, net of cash acquired		$88,462		$33,950		$88,071

The purchase price allocation of the Company's other fiscal 2013 acquisitions 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 2013, the Company recorded certain immaterial measurement period adjustments to the purchase price allocation of its other fiscal 2012 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 Blue Aerospace, 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 Blue Aerospace and 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 2013 acquisitions were included in the Company’s results of operations from the effective acquisition dates. The amount of net sales and earnings of the fiscal 2013 acquisitions excluding Reinhold included in the Consolidated Statements of Operations is not material. Had the fiscal 2013 acquisitions excluding Reinhold been consummated as of the beginning of fiscal 2012, 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 and 2012 would not have been materially different than the reported amounts.

Additional Purchase Consideration

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 and 2011, the Company, through HEICO Electronic, paid $15.1 million and $6.6 million of such additional purchase consideration, respectively, of which $4.8 million and $4.1 million was accrued as of October 31, 2011 and October 31, 2010, respectively. The amounts paid in fiscal 2012 and 2011 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, 2013 and 2012, the Company had no remaining obligation to pay additional purchase consideration for acquisitions consummated prior to fiscal 2010.

Pursuant to the terms of the purchase agreements related to certain fiscal 2012 and 2011 acquisitions, the Company was obligated to pay additional purchase consideration representing the difference between the actual net assets of the acquired entity as of the acquisition date and the amount estimated in the purchase agreement. During fiscal 2013 and fiscal 2012 , the Company paid $1.2 million and $5.5 million of such additional purchase consideration, respectively.

		$7,263			$5,482

As discussed in Note 2, Acquisitions, the Company acquired Lucix Corporation in October 2013, which recognizes the majority of its revenue using the percentage-of-completion method. The acquired balances of costs incurred on uncompleted contracts, estimated earnings, billings to date, costs and estimated earnings in excess of billings, and billings in excess of costs and estimated earnings were $13.4 million, $15.3 million, $26.5 million, $4.7 million and $2.5 million, respectively,

Changes in estimates pertaining to percentage-of-completion contracts did not have a material effect on net income from consolidated operations in fiscal 2013, 2012 or 2011.

Inventories



	As of October 31,
(in thousands)	2013			2012
Finished products		$103,234			$93,873
Work in process	26,810			18,887
Materials, parts, assemblies and supplies	79,863			69,042
Contracts in process	9,941			8,299
Less: Billings to date	(955		)	(397		)
Inventories, net of valuation reserves		$218,893			$189,704

Contracts in process represents accumulated capitalized costs associated with fixed price contracts for which revenue is recognized on the completed-contract method. Related progress billings and customer advances (“billings to date”) are classified as a reduction to contracts in process, if any, and any excess is included in accrued expenses and other liabilities.

Property, Plant and Equipment



	As of October 31,
(in thousands)	2013			2012
Land		$4,515			$4,505
Buildings and improvements	60,105			54,322
Machinery, equipment and tooling	131,855			109,041
Construction in progress	4,932			5,599
	201,407			173,467
Less: Accumulated depreciation and amortization	(103,670		)	(92,949		)
Property, plant and equipment, net		$97,737			$80,518

The amounts set forth above include tooling costs having a net book value of $5.7 million and $6.0 million as of October 31, 2013 and 2012, respectively. Amortization expense on capitalized tooling was $2.2 million, $2.1 million and $2.1 million in fiscal 2013, 2012 and 2011, respectively.

The amounts set forth above also include $5.5 million and $5.2 million of assets under capital leases as of October 31, 2013 and October 31, 2012, respectively. Accumulated depreciation associated with the assets under capital leases was $1.1 million and $.6 million as of October 31, 2013 and October 31, 2012, 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 $13.4 million, $11.6 million and $8.6 million in fiscal 2013, 2012 and 2011, respectively.

Accrued Expenses and Other Current Liabilities



	As of October 31,
(in thousands)	2013		2012
Accrued employee compensation and related payroll taxes		$52,435		$41,307
Accrued customer rebates and credits	14,787		10,833
Deferred revenue	11,529		6,442
Accrued additional purchase consideration	9,142		2,917
Other	17,841		14,742
Accrued expenses and other current liabilities		$105,734		$76,241

The increase in accrued employee compensation and related payroll taxes principally reflects a higher level of accrued performance awards based on the improved consolidated operating results. The total customer rebates and credits deducted within net sales in fiscal 2013, 2012 and 2011 was $8.3 million, $2.8 million and $8.7 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 2013 and 2011 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 increase in accrued additional purchase consideration principally reflects the estimated amount of contingent consideration related to a fiscal 2013 acquisition. 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 2013, 2012 and 2011 totaled $4.3 million, $3.8 million and $3.6 million, respectively. The aggregate liabilities of the LCP were $51.9 million and $36.5 million as of October 31, 2013 and 2012, respectively, and are classified within other long-term liabilities in the Company’s Consolidated Balance Sheets. The assets of the LCP, totaling $52.7 million and $37.1 million as of October 31, 2013 and 2012, 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 $5.0 million and $4.2 million as of October 31, 2013 and 2012, 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, 2013 and 2012, 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.

GOODWILL AND OTHER INTANGIBLE ASSETS

Changes in the carrying amount of goodwill during fiscal 2013 and 2012 by operating segment are as follows (in thousands):



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

Foreign currency translation adjustments	—			1,991			1,991
Balances as of October 31, 2013		$279,855			$408,634			$688,489

The goodwill acquired during fiscal 2013 and 2012 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 adjustments to goodwill during fiscal 2013 represent immaterial measurement period adjustments to the purchase price allocations of certain fiscal 2012 acquisitions. The adjustments to goodwill during fiscal 2012 principally represent additional purchase consideration paid relating to a pre-fiscal 2010 acquisition for which the earnings objectives were met in fiscal 2012 as well as immaterial measurement period adjustments to the purchase price allocations of the fiscal 2011 acquisitions. See Note 2, Acquisitions, for additional information regarding additional purchase consideration. The foreign currency translation adjustments reflect unrealized translation gains on the goodwill recognized in connection with foreign subsidiaries. Foreign currency translation adjustments are included in other comprehensive income in the Company's Consolidated Statements of Comprehensive Income. The Company estimates that approximately $5 million and $21 million of the goodwill recognized in fiscal 2013 and 2012, respectively, will be deductible for income tax purposes. Based on the annual test for goodwill impairment as of October 31, 2013, 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):



	As of October 31, 2013							As of October 31, 2012
	Gross Carrying Amount		Accumulated Amortization			Net Carrying Amount		Gross Carrying Amount		Accumulated Amortization			Net Carrying Amount

		$294,126		($52,568	)		$241,558		$187,182		($32,858	)		$154,324

The increase in the gross carrying amount of customer relationships, intellectual property, and non-amortizing trade names as of October 31, 2013 compared to October 31, 2012 principally relates to such intangible assets recognized in connection with the acquisitions made during fiscal 2013 (see Note 2, Acquisitions). The weighted average amortization period of the customer relationships and intellectual property acquired during fiscal 2013 is 9 years and 11 years, respectively.

Amortization expense related to intangible assets was $20.6 million, $16.2 million and $7.6 million for the fiscal years ended October 31, 2013, 2012 and 2011, respectively. Amortization expense for each of the next five fiscal years and thereafter is estimated to be $28.0 million in fiscal 2014, $26.1 million in fiscal 2015, $24.2 million in fiscal 2016, $23.1 million in fiscal 2017, $20.9 million in fiscal 2018 and $62.3 million thereafter.

During fiscal 2011, the Company recognized impairment losses of approximately $4.3 million, $.5 million and $.2 million from the write-down of certain customer relationships, intellectual property and trade names, respectively. The impairment losses recognized in fiscal 2011 were within the ETG and due to reductions in the future cash flows associated with such intangible assets. 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 Statements of Operations and the impairment losses pertaining to intellectual property were recorded as a component of cost of goods sold.

As of October 31, 2013, the aggregate amount of long-term debt, excluding capital leases, that will mature within the next five years is $.1 million in fiscal 2014, $.1 million in fiscal 2015, $.2 million in fiscal 2016, $.2 million in fiscal 2017 and $0.0 million in fiscal 2018. The aforementioned information has been adjusted to reflect an extension of the maturity date of the Company's revolving credit facility as further discussed below.

Capital Lease Obligations

In connection with an acquisition, the Company assumed 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 February 2011. Additionally, the acquisition resulted in the Company assuming various capital leases for manufacturing equipment. The manufacturing equipment leases have 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):



Year ending October 31,

Total minimum lease payments	4,576
Less: amount representing interest	(716		)
Present value of minimum lease payments		$3,860

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.

On November 22, 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, 2013 and 2012, the weighted average interest rate on borrowings under the Credit Facility was 1.3% and 1.2%, respectively. The Credit Facility contains both financial and non-financial covenants. As of October 31, 2013, 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,
	2013		2012		2011
Federal statutory income tax rate	35.0	%	35.0	%	35.0	%

Other, net	(.5	)	.9		.5
Effective tax rate	31.1	%	33.8	%	31.0	%

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,
	2013			2012
Deferred tax assets:
Deferred compensation liability		$22,242			$15,805
Inventories	21,673			18,536

Property, plant and equipment	(12,486		)	(8,950		)
Other	(1,154		)	(712		)
Total deferred tax liabilities	(162,351		)	(112,491		)
Net deferred tax liability		($93,655	)		($60,399	)

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



	As of October 31,
	2013			2012
Current asset		$33,036			$27,545
Long-term asset	1,791			2,492
Long-term liability	(128,482		)	(90,436		)
Net deferred tax liability		($93,655	)		($60,399	)

The increase in the Company's net deferred tax liability from $60.4 million as of October 31, 2012 to $93.7 million as of October 31, 2013 is principally related to the net deferred tax liabilities recognized in connection with the acquisitions of Reinhold and Lucix (see Note 2, Acquisitions), partially offset by an increase in the deferred tax asset related to a higher deferred compensation liability for the HEICO Corporation Leadership Compensation Plan ("LCP"). The deferred income tax benefit recognized in fiscal 2013 principally reflects the increase in the deferred tax asset related to the higher LCP liability resulting from both increased investment earnings and plan contributions.

As of October 31, 2013 and 2012, the Company’s liability for gross unrecognized tax benefits related to uncertain tax positions was $1.1 million and $2.5 million, respectively, of which $.8 million and $1.7 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, 2013 and 2012 is as follows (in thousands):



	Year ended October 31,
	2013			2012
Balances as of beginning of year		$2,527			$1,834
Increases related to prior year tax positions	58			1,281
Decreases related to prior year tax positions	(967		)	(240		)
Increases related to current year tax positions	108			299
Settlements	(570		)	(52		)
Lapse of statutes of limitations	(84		)	(595		)
Balances as of end of year		$1,072			$2,527

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’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's net liability for unrecognized tax benefits was $2.3 million as of October 31, 2012, including $.7 million of interest and penalties and net of $1.0 million in deferred tax assets. The Company recognized interest and penalties of ($.2) million, $.4 million and less than $.1 million in fiscal 2013, 2012 and 2011, respectively, related to unrecognized tax benefits.

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 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 pursuant to the retroactive extension of Section 41 of the Internal Revenue Code, "Credit for Increasing Research Activities," 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 an income tax deduction under Section 404(k) of the Internal Revenue Code for the one-time special and extraordinary cash dividend paid in December 2012 to participants of the HEICO Savings and Investment Plan holding HEICO common stock.

The Company's effective tax rate increased to 33.8% in fiscal 2012 from 31.0% in fiscal 2011. The change in the effective tax rate is partially attributed to the retroactive extension of Section 41 of the Internal Revenue Code, “Credit for Increasing Research Activities,” to cover the period from January 1, 2010 to December 31, 2011, which resulted in the recognition of an income tax credit for qualified research and development activities for the last ten months of fiscal 2010 in the first quarter of fiscal 2011 and reduced the recognition of such income tax credit to just the first two months of qualifying research and development activities in fiscal 2012. In addition, the Company purchased certain noncontrolling interests during fiscal 2011 and 2012 that contributed to the comparative increase in the effective tax rate for fiscal 2012. Further, the increase also reflects a higher effective state income tax rate principally because fiscal 2011 includes the aforementioned benefit from state income apportionment updates recognized upon the filing of the Company's fiscal 2010 state tax returns and the amendment of certain prior year state tax returns in the third quarter of fiscal 2011 and fiscal 2012 includes the effect of a fiscal 2012 acquisition and changes in certain state tax laws which impacted state apportionment factors.

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 2009.

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

The Company maintains two non-qualified deferred compensation plans. The assets of the HEICO Corporation Leadership Compensation Plan (the “LCP”) 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. The assets of the Company's other deferred compensation plan are principally invested in equity securities, mutual funds and money market funds that are classified within Level 1. 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 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. The $8.6 million estimated fair value of the contingent consideration as of October 31, 2013 is classified within Level 3 and was determined using a probability-based scenario analysis approach. Under this method, a set of discrete potential future subsidiary earnings was determined using internal estimates based on various revenue growth rate assumptions for each scenario that ranged from a compound annual growth rate of negative 5% to positive 19%. A probability of likelihood was assigned to each discrete potential future earnings estimate and the resultant contingent consideration was calculated. The resulting probability-weighted contingent consideration amounts were discounted using a weighted average discount rate of 3.0% 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 $1.7 million decrease in the fair value of the contingent consideration since October 31, 2012 is principally attributed to lower year one actual earnings and year two forecasted earnings of the subsidiary due to reductions in United States defense spending and was recorded to selling, general and administrative expenses in the Company's Consolidated Statement of Operations. As of October 31, 2013, the estimated amount of such contingent consideration to be paid is included in other long-term liabilities in the Company's Consolidated Balance Sheet.

As part of the agreement to acquire a subsidiary by the ETG in fiscal 2013, the Company may be obligated to pay contingent consideration of up to $50.0 million in aggregate should the acquired entity meet certain earnings objectives during the last three months of the calendar year of acquisition and during the subsequent two calendar years (2014 and 2015). The $20.7 million estimated fair value of the contingent consideration as of October 31, 2013 is classified within Level 3 and was determined using a probability-based scenario analysis approach. Under this method, a set of discrete potential future subsidiary earnings was determined using internal estimates based on various revenue growth rate assumptions for each scenario that ranged from a compound annual growth rate of negative 4% to positive 31%. A probability of likelihood was assigned to each discrete potential future earnings estimate and the resultant contingent consideration was calculated. The resulting probability-weighted contingent consideration amounts were discounted using a weighted average discount rate of 2.5% 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. As of October 31, 2013, the estimated amount of such contingent consideration to be paid within the next twelve months of $7.0 million is included in accrued expenses and other current liabilities and the remaining $13.7 million is included in other long-term liabilities in the Company’s Consolidated Balance Sheet.

Changes in the Company’s assets and liabilities measured at fair value on a recurring basis using unobservable inputs (Level 3) for the fiscal years ended October 31, 2013 and 2012 are as follows (in thousands):

The Company did not have any transfers between Level 1 and Level 2 fair value measurements during fiscal 2013 and 2012.

The carrying amounts of the Company’s cash and cash equivalents, accounts receivable, trade accounts payable and accrued expenses and other current liabilities approximate fair value as of October 31, 2013 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 2011, certain intangible assets within the ETG were measured at fair value on a nonrecurring basis resulting in the recognition of impairment losses aggregating $5.0 million (See Note 4, Goodwill and Other Intangible Assets). The fair value of each asset was determined using a discounted cash flow model and internal estimates of each asset's future cash flows.

SHAREHOLDERS' EQUITY	12 Months Ended
SHAREHOLDERS' EQUITY	Oct. 31, 2013
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, and after making provision for the holders of preferred stock, if any, the remaining assets of the Company will be distributable ratably among the holders of all classes of common stock. Stock Splits In September 2013, March 2012 and March 2011, 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, April 25, 2012 and April 26, 2011, respectively, in the form of a 25% stock dividend distributed to shareholders of record as of October 11, 2013, April 13, 2012 and April 15, 2011, 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, 2013, 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 2013, 2012 and 2011, the Company did not repurchase any shares of Company common stock under this program. 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. During fiscal 2011, the Company repurchased an aggregate 420,066 shares of Common Stock at a total cost of approximately $13.6 million and an aggregate 34,843 shares of Class A Common Stock at a total cost of approximately $.7 million. The transactions in fiscal 2013, 2012 and 2011 occurred as settlement for employee taxes due pertaining to exercises of non-qualified stock options, 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 stock option exercises in the Company's Consolidated Statements of Shareholders' Equity and the Company's Consolidated Statements of Cash Flows. In December 2012, the Company paid a special and extraordinary $1.712 per share cash dividend on both classes of HEICO common stock as well as a regular semi-annual $.048 per share cash dividend that was accelerated from January 2013. The dividends, which aggregated $116.6 million, were funded from borrowings under the Company's revolving credit facility.

- 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.

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

STOCK OPTIONS

The Company currently has one stock option plan, the HEICO Corporation 2012 Incentive Compensation Plan (“2012 Plan”), under which stock options may be granted. 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 5.0 million shares of the Company's common stock are reserved for issuance to employees, directors, officers and consultants as of October 31, 2013, including 3.1 million shares currently under option and 1.8 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 stock option 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, 2013, 2012 and 2011 includes compensation expense of $5.1 million, $3.9 million and $2.6 million, respectively, and an income tax benefit of $2.0 million, $1.5 million and $1.0 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, 2013, there was $18.8 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 3.7 years. The total fair value of stock options that vested in fiscal 2013, 2012 and 2011 was $4.5 million, $3.6 million and $2.1 million, respectively. If there were a change in control of the Company, all of the unvested options outstanding as of October 31, 2013 would become immediately exercisable.

For the fiscal years ended October 31, 2013, 2012 and 2011, the excess tax benefit resulting from tax deductions in excess of the cumulative compensation cost recognized for stock options exercised was $5.1 million, $12.1 million and $6.3 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, 2013, 2012 and 2011:

Compensation and Retirement Disclosure [Abstract]

Pension and Other Postretirement Benefits Disclosure [Text Block]

RETIREMENT PLANS

The Company has a qualified defined contribution retirement plan (the “401(k) Plan”) under which eligible employees of the Company and its participating subsidiaries may make Elective Deferral Contributions up to the limitations set forth in Section 402(g) of the Internal Revenue Code. The Company generally makes a 25% or 50% Employer Matching Contribution, as determined by the Board of Directors, based on a participant’s Elective Deferral Contribution up to 6% of the participant’s Compensation for the Elective Deferral Contribution period. The Employer Matching Contribution may be contributed to the 401(k) Plan in the form of the Company’s common stock or cash, as determined by the Company. The Company’s match of a portion of a participant’s contribution is invested in Company common stock and is based on the fair value of the shares as of the date of contribution. The 401(k) Plan also provides that the Company may contribute to the 401(k) Plan additional amounts in its common stock or cash at the discretion of the Board of Directors. Employee contributions cannot be invested in Company common stock.

Participants receive 100% vesting of employee contributions and cash dividends received on Company common stock. Vesting in Company contributions is based on a participant’s number of years of vesting service. Contributions to the 401(k) Plan charged to income in fiscal 2013 and fiscal 2012 totaled $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. Contributions to the 401(k) Plan charged to income in fiscal 2011 was less than $.1 million and was made with the use of forfeited shares within the 401(k) Plan.

In connection with the acquisition of Reinhold (see Note 2, Acquisitions), the Company assumed Reinhold's 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 and therefore the Plan's accumulated benefit obligation is equal to the projected benefit obligation. The acquired projected benefit obligation and plan assets were recorded at fair value as of the acquisition date.

Changes in the Plan's projected benefit obligation and plan assets since the acquisition are as follows (in thousands):



Change in projected benefit obligation:
Acquired projected benefit obligation		$14,539
Actuarial gain	(1,165		)
Interest cost	236
Benefits paid	(397		)
Projected benefit obligation as of October 31, 2013		$13,213

Change in plan assets:
Acquired plan assets		$11,674
Actual return on plan assets	120
Benefits paid	(397		)
Fair value of plan assets as of October 31, 2013		$11,397

Funded status as of October 31, 2013		($1,816	)

The $1.8 million difference between the projected benefit obligation and fair value of plan assets as of October 31, 2013 was included in other long-term liabilities within the Company's Consolidated Balance Sheet. Additionally, the Plan experienced a $1.0 million net actuarial gain during fiscal 2013 that was recognized in other comprehensive income (where it is reported net of $.4 million of tax) and represents the total balance in accumulated other comprehensive income that has yet to be recognized as a component of net periodic pension income as of October 31, 2013. The Company does not expect to recognize any of the amount within accumulated other comprehensive income as of October 31, 2013 as a component of net periodic pension income during fiscal 2014.

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



	Projected Benefit Obligation		Net Benefit Income
Discount rate	4.79	%	3.99	%
Expected return on plan assets	N/A		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 since the acquisition within the Company's fiscal 2013 Statement of Operations are as follows (in thousands):



Expected return on plan assets		$320
Interest cost	236
Net pension income		$84

The Company has not made any contributions to the Plan since the acquisition and anticipates making contributions of $.1 million during fiscal 2014. 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):



Year ending October 31,
2014		$964
2015	937
2016	919
2017	905
2018	873
2019-2023	4,313

The following table sets forth by level within the fair value hierarchy, the fair value of the Plan's assets as of October 31, 2013 (in thousands):



	As of October 31, 2013
	Quoted Prices in Active Markets for Identical Assets (Level 1)		Significant Other Observable Inputs (Level 2)		Significant Unobservable Inputs (Level 3)		Total
Fixed income securities		$9,060		$—		$—		$9,060
Equity securities	2,212		—		—		2,212
Money market funds and cash	125		—		—		125
		$11,397		$—		$—		$11,397

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

The Plan's actual and targeted asset allocations by asset category as of October 31, 2013 were as follows:



	As of October 31, 2013
	Actual Allocation		Target Allocation
Fixed income securities	80	%	80	%
Equity securities	19	%	20	%
Money market funds and cash	1	%	—	%
Total	100	%	100	%

The Company is currently evaluating the Plan's asset allocation policy which was established prior to the acquisition. The Company's objective is to maximize long-term investment return while maintaining an acceptable level of risk that is accomplished through broad diversification of the Plan's assets.

REDEEMABLE NONCONTROLLING INTERESTS	12 Months Ended
REDEEMABLE NONCONTROLLING INTERESTS	Oct. 31, 2013
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, 2013, management’s estimate of the aggregate Redemption Amount of all Put Rights that the Company would be required to pay is approximately $59 million. The actual Redemption Amount will likely be different. The aggregate Redemption Amount of all Put Rights was determined using probability adjusted internal estimates of future earnings of the Company’s subsidiaries with Put Rights while considering the 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, 2013 redeemable at fair value is approximately $48 million and the portion redeemable based solely on a multiple of future earnings is approximately $11 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 2013, 2012 and 2011 is as follows: The Company acquired an 80.1% interest in a subsidiary by the ETG in fiscal 2004. As part of the purchase agreement, the noncontrolling interest holders currently have the right to cause the Company to purchase their interests over a five-year period ending in fiscal 2018 and the Company has the right to purchase the noncontrolling interests over a five-year period beginning in fiscal 2015, or sooner under certain conditions. Pursuant to the purchase agreement related to the acquisition of an 85% interest in a subsidiary by the ETG in fiscal 2005, 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 fiscal 2007 and in fiscal 2009 to cause the Company to purchase their aggregate 3% and 10.5% interest, respectively. Accordingly, the Company increased its ownership interest in the subsidiary by an aggregate 10.9% to 95.9% effective April 2011. During fiscal 2012, the Company and the noncontrolling interest holder of the aforementioned 10.5% interest agreed to defer the purchase of the remaining 2.6% interest to a future period. 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. The Company acquired an 80.1% interest in a subsidiary by 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 beginning in fiscal 2014 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 by the ETG in fiscal 2009. As part of the purchase agreement, the Company has the right to purchase the noncontrolling interests beginning in fiscal 2014 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 by 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 by the FSG in fiscal 2012.

The purchase prices of the redeemable noncontrolling interests acquired in fiscal 2012 and 2011 were paid using cash provided by operating activities. The aggregate cost of the redeemable noncontrolling interests acquired was $16.6 million, $7.6 million and $7.2 million in fiscal 2013, 2012 and 2011, respectively.
