	SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
	Nature of Operations Entegris is a leading provider of yield-enhancing materials and solutions for advanced manufacturing processes in the semiconductor and other high-technology industries.
	Principles of Consolidation The condensed consolidated financial statements include the accounts of the Company and its majority-owned subsidiaries. Intercompany profits, transactions and balances have been eliminated in consolidation.
	Use of Estimates The preparation of condensed consolidated financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, particularly receivables, inventories, property, plant and equipment, and intangibles, accrued expenses and income taxes and related accounts, and disclosure of contingent assets and liabilities at the date of the condensed consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.
	Basis of Presentation The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States and contain all adjustments (consisting of only normal recurring adjustments) necessary to present fairly the financial position as of June 28, 2014 and December 31, 2013, and the results of operations, comprehensive (loss) income and cash flows for the three and six months ended June 28, 2014 and June 29, 2013.
	The condensed consolidated financial statements and notes are presented as permitted by Form 10-Q and do not contain certain information included in the Company’s annual consolidated financial statements and notes. The information included in this Form 10-Q should be read in conjunction with Management’s Discussion and Analysis and consolidated financial statements and notes thereto included in the Company’s Form 10-K for the year ended December 31, 2013. The results of operations for the three and six months ended June 28, 2014 are not necessarily indicative of the results to be expected for the full year.
	Recent Accounting Pronouncements
	In May 2014, the FASB issued Accounting Standards Update No. 2014-09, Revenue from Contracts with Customers (Topic 606)(ASU 2014-09). ASU 2014-09 outlines a new, single comprehensive model for entities to use in accounting for revenue arising from contracts with customers and supersedes most current revenue recognition guidance, including industry-specific guidance. This new revenue recognition model provides a five-step analysis in determining when and how revenue is recognized. The new model will require revenue recognition to depict the transfer of promised goods or services to customers in an amount that reflects the consideration a company expects to receive in exchange for those goods or services. ASU 2014-09 is effective for the quarter ending March 31, 2017. The Company is currently assessing the impact that adopting this new accounting guidance will have on its consolidated financial statements and disclosures.
	Other Accounting Standards Updates issued but not effective for the Company until after June 28, 2014 are not expected to have a material effect on the Company’s condensed consolidated financial statements.

	ACQUISTIONS
	ATMI
	On April 30, 2014, the Company acquired ATMI, Inc. (the Merger), a Delaware corporation (ATMI), for approximately $1.1 billion in cash pursuant to an Agreement and Plan of Merger (the Merger Agreement), dated as of February 4, 2014. As a result of the Merger, ATMI became a wholly-owned subsidiary of the Company. The Merger was accounted for under the acquisition method of accounting and the results of operations of ATMI are included in the Company's condensed consolidated financial statements as of and since April 30, 2014. Direct costs of $12.0 million and $13.3 million associated with the acquisition of ATMI, consisting mainly of professional and consulting fees, were expensed as incurred in the three and six months ended June 28, 2014, respectively. These costs are classified as selling, general and administrative expense in the Company's condensed consolidated statement of operations.
	ATMI is a leading supplier of high-performance materials, materials packaging and materials delivery systems used worldwide in the manufacture of microelectronic devices. Its products consist of “front-end” semiconductor performance materials, sub-atmospheric pressure gas delivery systems for safe handling and delivery of toxic and hazardous gases, and high-purity materials packaging and dispensing systems that allow for the reliable introduction of low volatility liquids and solids to microelectronics processes. The acquisition was executed to expand the Company’s product offering base and technological base, and enhance the leverage of its selling and administrative functions. ATMI’s sales for the year ended December 31, 2013 were approximately $361 million.
	The purchase price of ATMI consisted of the following:
	(In thousands):
	Cash paid to ATMI shareholders	$	1,099,033
	Cash paid in settlement of shared-based compensation awards	31,001
	Total purchase price	1,130,034
	Less cash and cash equivalents acquired	321,094
	Total purchase price, net of cash acquired	$	808,940
	Under the terms of the Merger Agreement, the Company paid $34 per share for all outstanding shares of ATMI (excluding treasury shares). In addition, the Company settled all outstanding share-based compensation awards held by ATMI employees at the same per share price. The acquisition method of accounting requires the Company to include the amount associated with pre-combination service as consideration in the acquisition, reflected in the table immediately above, while the fair value of the unvested portion of the awards in the amount of $21.3 million is recorded as expense, classified as selling, general and administrative expense, in the Company's condensed consolidated statement of operations.
	The Merger was funded with existing cash balances as well as funds raised by the Company through the issuance of debt in the form of a senior secured term loan in an aggregate principal amount of $460 million and senior unsecured notes in an aggregate principal amount of $360 million as described in further detail in note 5 to the condensed consolidated financial statements.
	The following table summarizes the allocation of the purchase price to the fair values assigned to the assets acquired and liabilities assumed at the date of the ATMI acquisition:
	(In thousands):
	Accounts receivable and other current assets	$	108,051
	Inventory	115,962
	Property, plant and equipment	123,641
	Identifiable intangible assets	296,726
	Other noncurrent assets	20,139
	Current liabilities	(72,804		)
	Deferred tax liabilities and other noncurrent liabilities	(98,877		)
	Net assets acquired	492,838
	Goodwill	316,102
	Total purchase price, net of cash acquired	$	808,940
	The fair value of acquired inventories of $116.0 million is provisional pending the Company's review of the calculations underlying the valuation for those assets and is valued at the estimated selling price less the cost of disposal and reasonable profit for the selling effort. The fair value write-up of acquired finished goods inventory was $48.6 million, the amount of which will be amortized over the expected turn of the acquired inventory. Accordingly, a $24.3 million incremental cost of sales charge associated with the fair value write-up of inventory acquired in the merger with ATMI was recorded for the three months ended June 28, 2014.
	The fair value of acquired property, plant and equipment of $123.6 million is provisional pending the Company's review of the valuation report for those assets from a third-party valuation firm and is valued at its value-in-use, unless there was a known plan to dispose of an asset.
	The fair value of the acquired intangible assets of $296.7 million is provisional pending the Company's review of the valuation report for those assets from a third-party valuation firm. The acquired intangible assets, all of which are finite-lived, have a weighted average useful life of approximately 8.2 years and are being amortized on a straight-line basis. The intangible assets that comprise the amount include customer relationships of $160.8 million (10-year weighted average useful life), technology and related trade names of $120.8 million (6-year weighted average useful life), and other intangible assets of $15.1 million (8- year weighted average useful life).
	The fair value of acquired identifiable intangible assets was determined using the “income approach” on an individual project basis. In performing these valuations, the key underlying probability-adjusted assumptions of the discounted cash flows were projected revenues, gross margin expectations and operating cost estimates. The valuations were based on the information that was available as of the acquisition date and the expectations and assumptions that have been deemed reasonable by the Company’s management. There are inherent uncertainties and management judgment required in these determinations. The fair value measurements of the assets acquired and liabilities assumed were based on valuations involving significant unobservable inputs, or Level 3 in the fair value hierarchy.
	The purchase price of ATMI exceeded the net of the acquisition-date amounts of the identifiable assets acquired and the liabilities assumed by $316.1 million. Cash flows used to determine the purchase price included strategic and synergistic benefits (investment value) specific to the Company, which resulted in a purchase price in excess of the fair value of identifiable net assets. The purchase price also included the fair values of other assets that were not identifiable, not separately recognizable under accounting rules (e.g., assembled workforce) or of immaterial value in addition to a going-concern element that represents the Company's ability to earn a higher rate of return on the group of assets than would be expected on the separate assets as determined during the valuation process. This additional investment value resulted in goodwill. No amount of goodwill is expected to be deductible for tax purposes. The assignment of goodwill to the Company's reportable segments will be completed in connection with the final valuation of assets acquired and liabilities assumed.
	The final valuation of assets acquired and liabilities assumed is expected to be completed as soon as possible, but no later than one year from the acquisition date. Given the size and complexity of the acquisition, the valuation of certain assets and liabilities is still being finalized. In addition to inventory, property, plant and equipment, and identifiable intangible assets, for the reasons noted above, the Company's valuation of the ATMI's tax accounts is provisional pending the completion of and the Company's review of ATMI's tax returns to be filed for periods up to the acquisition date. To the extent that the Company's estimates require adjustment, the Company will modify the value.
	Subsequent to the Merger, the Company made severance payments of $7.5 million to ATMI executives. Under the terms of various agreements, the executives are unable to compete with the Company for periods averaging 1.6 years. Based on the Company's analysis, the payments associated with these noncompete clauses were capitalized as finite-lived intangible assets. The fair value of these noncompete clauses was determined using the “income approach” on an individual executive basis, following a methodology similar to the one described above for acquired identifiable intangible assets.
	Pro Forma Results
	The following unaudited pro forma financial information presents the combined results of operations of the Company as if the acquisition of ATMI had occurred as of the beginning of the years presented. The unaudited pro forma financial information is not necessarily indicative of what the Company’s consolidated results of operations actually would have been had the acquisition occurred at the beginning of each year. In addition, the unaudited pro forma financial information does not attempt to project the future results of operations of the combined company.

	The unaudited pro forma financial information above gives effect to the following:
	a.	The elimination of transactions between Entegris and ATMI, which upon completion of the merger would be considered intercompany. This reflects the elimination of intercompany sales and associated intercompany accounts.
	b.	Incremental amortization and depreciation expense related to the estimated fair value of identifiable intangible assets and property, plant and equipment from the purchase price allocation.
	c.	The above pro forma results have been reclassified to segregate the operating results of discontinued operations.
	The unaudited pro forma financial information above for the three and six months ended June 28, 2014 excludes the purchase accounting impact of the incremental charge of $24.3 million reported in cost of sales for the sale of acquired inventory that was written-up to fair value. The pro forma data does not include data for Jetalon Solutions, Inc. for the period prior to the acquisition thereof due to the immaterial impact on the pro forma financial information for the six months ended June 28, 2014.
	Jetalon
	On April 1, 2013, the Company acquired substantially all the operating assets and liabilities of Jetalon Solutions, Inc. (Jetalon), a California-based supplier of fluid metrology products. The transaction was accounted for under the acquisition method of accounting and the results of operations of the entity are included in the Company's condensed consolidated financial statements as of and since April 1, 2013. The acquisition of Jetalon’s assets and liabilities did not constitute a material business combination.
	The purchase price for Jetalon included cash consideration of $13.4 million, funded from the Company's then-existing cash on hand, and earnout-based contingent consideration of up to $14.5 million based on the operating performance of Jetalon in 2013, 2014 and 2015. Costs associated with the acquisition of Jetalon were not significant and were expensed as incurred.
	Upon acquisition, the Company recorded a contingent consideration obligation of $3.1 million representing the fair value of the earnout-based contingent consideration. This amount was estimated through a valuation model that incorporates probability-adjusted assumptions relating to the achievement of possible operating results and the likelihood of the Company making payments. This fair value measurement is based upon significant inputs not observable in the market and therefore represents a Level 3 measurement.
	Subsequent changes in the fair value of this obligation have been recognized as adjustments to the contingent consideration obligation and reflected in the Company's condensed consolidated statements of operations. During the quarter ended June 28, 2014, the Company assessed the contingent consideration based on the valuation methodology described above and recorded a $1.3 million gain in the Company's condensed consolidated statements of operations, reflecting the removal of any remaining contingent consideration obligation.
	The purchase price of Jetalon consisted of the following:
	(In thousands):
	Cash paid at closing	$	13,358
	Contingent consideration obligation	3,094
	Total purchase price	$	16,452
	The purchase price of Jetalon, including the Company's valuation of contingent consideration, exceeded the net of the acquisition-date amounts of the identifiable assets acquired and the liabilities assumed by $10.1 million. Cash flows used to determine the purchase price included strategic and synergistic benefits (investment value) specific to the Company, which resulted in a purchase price in excess of the fair value of identifiable net assets. The purchase price also included the fair values of other assets that were not identifiable, not separately recognizable under accounting rules (e.g., assembled workforce) or of immaterial value in addition to a going-concern element that represents the Company's ability to earn a higher rate of return on the group of assets than would be expected on the separate assets as determined during the valuation process. This additional investment value resulted in goodwill, which is expected to be deductible for income tax purposes. The goodwill has been assigned to the Company's Critical Materials Handling reportable segment.
	The following table summarizes the allocation of the purchase price to the fair values assigned to the assets acquired and liabilities assumed at the date of the Jetalon acquisition:
	(In thousands):
	Accounts receivable, inventory and other assets		$	944
	Identifiable intangible assets		5,634
	Current liabilities		(216		)
	Net assets acquired		6,362
Goodwill		10,090
Total purchase price		$	16,452
The Company completed its fair value determinations for all elements of the Jetalon acquisition in 2013. Intangible assets, consisting mostly of technology-related intellectual property, are being amortized on a straight-line basis over an estimated useful life of approximately 10 years.

	SHORT-TERM INVESTMENTS
	In conjunction with the acquisition of ATMI, the Company acquired South Korea bank time deposits and common shares of one security, which are classified as available-for-sale and are reported at fair value, with unrealized gains and losses included in shareholders’ equity as a component of accumulated other comprehensive income, net of applicable taxes. Available-for-sale investments as of June 28, 2014 consist of the following:
	(In thousands)	Cost			Gross			Gross			Fair

					losses
	Common stock	$	6,040		$	(1,011	)
	Total	$	6,040		$	(1,011	)
	The Company regularly reviews the fair value of marketable security declines below amortized cost to evaluate whether the decline is other-than-temporary. In making this determination, the Company considers all available evidence including, among other things, considering the duration and extent of the decline and the economic factors influencing the market to determine if the fair value will recover to equal or exceed the amortized cost. If the Company determines that the fair value will not recover, an other-than-temporary impairment is recognized, net of applicable taxes. Management does not believe the unrealized losses represent other-than-temporary impairments based on our evaluation of available evidence as of June 28, 2014. As part of that evaluation, the Company has concluded that it has the ability and intent to hold the investment until the recovery of fair value.
	The amortized cost and fair value of available-for-sale debt investments as of June 28, 2014, by contractual maturity, were as follows:

	As described in note 2 to the condensed consolidated financial statements, the Company issued debt with a principal amount of $820 million to supply the funding required to complete its acquisition of ATMI. Debt issuance costs of $2.3 million paid directly to lending institutions are recorded as a debt discount, while debt issuance costs of $20.7 million paid to third parties are capitalized as debt issuance costs, and reflected within other current and other noncurrent assets. These debt issuance costs are being amortized as interest expense over the term of the debt instrument using the effective-interest method for the senior secured term loan facility and senior unsecured notes, and the straight-line method for the senior secured asset-based revolving credit facility.
	During the quarter ended June 28, 2014, the Company recorded $4.3 million of amortized debt issuance costs, including $4.0 million for bridge financing fees paid for the availability of funding for the acquisition of ATMI. This amount is included in interest expense in the Company's condensed consolidated statements of operations.
	2022 Senior Unsecured Notes
	On April 1, 2014, the Company issued $360 million aggregate principal amount of 6% senior unsecured notes due April 1, 2022 (the 2022 Senior Unsecured Notes). The 2022 Senior Unsecured Notes were issued under an indenture dated as of April 1, 2014 (the 2022 Senior Unsecured Notes Indenture) by and among the Company and Wells Fargo Bank, National Association, as trustee (the 2022 Senior Unsecured Notes Trustee). Interest on the 2022 Senior Unsecured Notes is payable semi-annually in arrears on April 1 and October 1, commencing October 1, 2014.
	The 2022 Senior Unsecured Notes are guaranteed, jointly and severally, fully and unconditionally, on an unsecured senior basis, by each of the Company’s domestic subsidiaries (the Guarantors) that guarantee indebtedness under the Company’s senior secured term loan facility and senior secured asset-based revolving credit facility (Senior Secured Credit Facilities).
	At any time prior to April 1, 2017, the Company may at its option on one or more occasion redeem all or a part of the 2022 Senior Unsecured Notes at a redemption price equal to 100% of the principal amount of the 2022 Senior Unsecured Notes redeemed plus a make-whole premium, as provided in the 2022 Senior Unsecured Notes Indenture, and accrued and unpaid interest.
	On and after April 1, 2017, the Company may, at its option, on one or more occasion, redeem all or part of the 2022 Senior Unsecured Notes, upon notice as provided in the 2022 Senior Unsecured Notes Indenture, at the redemption price (expressed as a percentage of principal amount between 100% and 104.5% depending on the period of redemption).
	Upon a change in control, the Company is required to offer to purchase all of the 2022 Senior Unsecured Notes at a price in cash equal to 101% of the aggregate principal amount thereof, plus accrued and unpaid interest, if any, to, but not including, the date of purchase.
	If the Company or its subsidiaries engage in asset sales, the Company generally must either invest the net cash proceeds from such sales in its business within a period of time, prepay debt under the Senior Secured Credit Facilities or make an offer to purchase a principal amount of the 2022 Senior Unsecured Notes equal to the excess net cash proceeds, subject to certain exceptions. The purchase price of the 2022 Senior Unsecured Notes will be 100% of their principal amount, plus accrued and unpaid interest, if any, to, but not including, the date of purchase.
	The 2022 Senior Unsecured Notes Indenture contains covenants that, among other things, limit the Company’s ability and the ability of the Company’s restricted subsidiaries to pay dividends or distributions or redeem or repurchase equity; prepay subordinated debt or make certain investments, loans, advances and acquisitions; incur or guarantee additional debt, or issue certain disqualified stock and preferred stock; create liens; engage in a consolidation or merger, or sell, transfer or otherwise dispose of all or substantially all of their assets; enter into transactions with affiliates; and create restrictions on the payment of dividends or other amounts to the Company from its restricted subsidiaries. The Company is in compliance with all of the above covenants at June 28, 2014.
	The 2022 Senior Unsecured Notes Indenture also provides for events of default which, if certain of them occur, would permit the 2022 Senior Unsecured Notes Trustee or the holders of at least 25% in aggregate principal amount of the then total outstanding 2022 Senior Unsecured Notes to declare the principal, premium, if any, interest and any other monetary obligations on all the then-outstanding 2022 Senior Unsecured Notes to be due and payable immediately.
	Senior Secured Asset-Based Revolving Credit Facility and Security Agreement
	On April 30, 2014, the Company entered into an asset-based credit agreement with Goldman Sachs Bank USA, as administrative agent, collateral agent, sole lead arranger, sole bookrunner and sole syndication agent (the ABL Facility), that provides senior secured financing of $75 million (which may be increased by up to $35 million in certain circumstances), subject to a borrowing base limitation. The borrowing base for the ABL Facility at any time equals the sum of certain percentages of various accounts and inventories. The ABL Facility includes borrowing capacity in the form of letters of credit up to the entire amount of the facility, and up to $20 million in U.S. dollars for borrowings on same-day notice, referred to as swingline loans, and is available in U.S. dollars. There is no outstanding balance under the ABL Facility at June 28, 2014.
	Borrowings under the ABL Facility bear interest at a rate per annum equal to, at the Company’s option, a base rate (prime rate or LIBOR), plus an applicable margin. The Company's interest rate is 4.25% at June 28, 2014. Swingline loans shall bear interest at a rate per annum equal to the base rate plus the applicable margin.
	In addition to paying interest on outstanding principal under the ABL Facility, the Company is required to pay a commitment fee in respect of the unutilized commitments thereunder. The initial commitment fee is 0.33% per annum. The Company must also pay customary letter of credit fees and agency fees.
	If at any time the aggregate amount of outstanding loans, unreimbursed letter of credit drawings and undrawn letters of credit under the ABL Facility exceeds the lesser of (a) the commitment amount and (b) the borrowing base, the Company is required to repay outstanding loans and/or cash collateralize letters of credit, with no reduction of the commitment amount.
	The Company may voluntarily reduce the unutilized portion of the commitment amount and repay outstanding loans at any time. Prepayments of the loans may be made without premium or penalty other than customary “breakage” costs with respect to LIBOR loans.
	There is no scheduled amortization under the Company’s ABL Facility. The principal amount outstanding under the ABL Facility is due and payable in full on the fifth anniversary of the closing date.
	All obligations under the ABL Facility are unconditionally guaranteed by certain of the Company’s existing wholly owned domestic subsidiaries and are required to be guaranteed by certain of the Company’s future wholly owned domestic subsidiaries. All obligations under the ABL Facility, and the guarantees of those obligations, are secured, subject to certain exceptions, by substantially all of the Company’s assets and the assets of the Company's subsidiaries that have guaranteed the ABL Facility.
	The ABL Facility contains a number of negative covenants that, among other things are subject to certain exceptions, restrict the Company’s ability and the ability of each of the Company’s subsidiaries to incur additional indebtedness; pay dividends on its capital stock or redeem, repurchase or retire its capital stock or its other indebtedness; make investments, loans and acquisitions; create restrictions on the payment of dividends or other amounts to the Company from the Company’s restricted subsidiaries; engage in transactions with its affiliates; sell assets, including capital stock of its subsidiaries; materially alter the business it conducts; consolidate or merge; incur liens; and engage in sale-leaseback transactions. The Company is in compliance with all of the above covenants at June 28, 2014.
	The credit agreement governing the ABL Facility additionally contains certain customary representations and warranties, affirmative covenants and provisions relating to events of default.
	Senior Secured Term Loan Facility and Security Agreement
	On April 30, 2014, the Company entered into a term loan credit and guaranty agreement with Goldman Sachs Bank USA, as administrative agent, collateral agent, sole lead arranger, sole bookrunner and sole syndication agent (the "Term Loan Facility"), that provides senior secured financing of $460 million (which may be increased by up to $225 million in certain circumstances). Borrowings under the Term Loan Facility bear interest at a rate per annum equal to, at the Company’s option, a base rate (such as prime rate or LIBOR) plus, an applicable margin. The Company's interest rate is 3.5% at June 28, 2014. In addition to paying interest on outstanding principal under the Term Loan Facility, the Company is required to pay customary agency fees.
	The credit agreement governing the Term Loan Facility requires the Company to prepay outstanding term loans, subject to certain exceptions, with:
	•	50% (subject to reduction to 25% and 0% based upon the Company’s senior secured net leverage ratio) of the Company’s annual Excess Cash Flow (as defined in the credit agreement governing the Term Loan Facility);
	•	100% of the net cash proceeds of certain asset sales and casualty and condemnation events, subject to reinvestment rights and certain other exceptions; and
	•	100% of the net cash proceeds of any incurrence or issuance of certain debt, other than debt permitted under the Term Loan Facility.
	The Company may voluntarily prepay outstanding loans under the Term Loan Facility at any time without premium or penalty other than customary “breakage” costs with respect to LIBOR loans, provided, however, that if on or prior to the date that is six months after the closing date of the Term Loan Facility, the Company prepays any loan in connection with a repricing transaction, the Company must pay a prepayment premium of 1.0% of the aggregate principal amount of the loans so prepaid.
	The Company is required to remit scheduled quarterly payments each equal to 0.25% of the original principal amount of the term loans made on the closing date, with the balance due on the seventh anniversary of the closing date.
	All obligations under the Term Loan Facility are unconditionally guaranteed by certain of the Company’s existing wholly owned domestic subsidiaries, and are required to be guaranteed by certain of the Company’s future wholly owned domestic subsidiaries. All obligations under the Term Loan Facility, and the guarantees of those obligations, are secured, subject to certain exceptions, by substantially all of the Company’s assets and the assets of the Company's subsidiary guarantors.
	The Term Loan Facility contains a number of negative covenants that, subject to certain exceptions, restrict the Company’s ability and each of the Company’s subsidiaries ability to incur additional indebtedness; pay dividends on its capital stock or redeem, repurchase or retire its capital stock or its other Indebtedness; make investments, loans and acquisitions; create restrictions on the payment of dividends or other amounts to the Company from the Company’s restricted subsidiaries; engage in transactions with its affiliates; sell assets, including capital stock of its subsidiaries; materially alter the business it conducts; consolidate or merge; incur liens; and engage in sale-leaseback transactions. The Company is in compliance with all of the above covenants at June 28, 2014.
	Intercreditor Agreement
	In connection with the closing of the ABL Facility and Term Loan Facility, on April 30, 2014, Goldman Sachs Bank USA, as collateral agent for the ABL Facility and as collateral agent for the Term Loan Facility, entered into an intercreditor agreement (the "Intercreditor Agreement"), which was acknowledged by the Company. The Intercreditor Agreement governs the relative priorities (and certain other rights) of the ABL Facility lenders and Term Loan Facility lenders pursuant the respective security agreements that each entered into with the Company and the guarantors.

	The Company’s year-to-date effective tax rate associated with the income tax benefit was 98.3% in 2014, compared to an effective tax rate of 26.0% in connection with income tax expense in 2013. This variance reflects changes in the Company's geographic composition of income toward jurisdictions with lower tax rates, nondeductibility of certain acquisition-related expenditures incurred in connection with the ATMI acquisition and the benefit of a foreign dividend. The effective tax rate in 2013 included a $1.3 million benefit associated with the reinstatement of the U.S. federal credit for increasing research expenditures, as retroactively signed into law and recorded by the Company in the first quarter of 2013.

	SEGMENT REPORTING
	Effective April 30, 2014, coincident to and in conjunction with the ATMI merger (see note 2 to the condensed consolidated financial statements) the Company changed its financial segment reporting to reflect management and organizational changes made by the Company. Under the new structure, the managers of two primary product groups are accountable for results at the segment profit level and report directly to the Company’s Chief Executive Officer, who is responsible for evaluating companywide performance and resource allocation decisions between the product groups. Beginning with this report, the Company will report its financial performance based on two reportable segments: Critical Materials Handling and Electronic Materials. The Company's two reportable segments are business divisions that provide unique products and services.
	The Company's financial reporting segments are Critical Materials Handling (CMH) and Electronic Materials (EM).
	•	CMH: provides a broad range of products that filter, handle, dispense, and protect critical materials used in the semiconductor manufacturing process and in other high-technology manufacturing. CMH’s products and subsystems include high-purity materials packaging, fluid handling and dispensing systems and liquid filters as well as microenvironment products that protect critical substrates such as wafers during shipping and manufacturing. CMH also provides specialized graphite components and specialty coatings for high-temperature applications.
	•	EM: provides high performance materials, materials packaging and materials delivery systems that enable high yield, cost effective semiconductor manufacturing. EM’s products consist of specialized chemistries and performance materials, gas microcontamination control systems and components, and sub-atmospheric pressure gas delivery systems for the safe and efficient handling of hazardous gases to semiconductor process equipment.
	Inter-segment sales are not significant. Segment profit is defined as net sales less direct segment operating expenses, excluding certain unallocated expenses, consisting mainly of general and administrative costs for the Company’s human resources, finance and information technology functions as well as interest expense, amortization of intangible assets, charges for the fair value write-up of acquired inventory sold and contingent consideration fair value adjustments.
	Summarized financial information for the Company’s reportable segments is shown in the following tables. Periods up to March 30, 2014 have been restated to reflect the basis of segmentation presented below.

Summary of Significant Accounting Policies (Policies)	6 Months Ended

Nature of Operations	'
	Nature of Operations
Principles of Consolidation	'
	Principles of Consolidation The condensed consolidated financial statements include the accounts of the Company and its majority-owned subsidiaries. Intercompany profits, transactions and balances have been eliminated in consolidation.
Use of Estimates	'
	Use of Estimates The preparation of condensed consolidated financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, particularly receivables, inventories, property, plant and equipment, and intangibles, accrued expenses and income taxes and related accounts, and disclosure of contingent assets and liabilities at the date of the condensed consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.
Basis of Presentation	'
	Basis of Presentation The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States and contain all adjustments (consisting of only normal recurring adjustments) necessary to present fairly the financial position as of June 28, 2014 and December 31, 2013, and the results of operations, comprehensive (loss) income and cash flows for the three and six months ended June 28, 2014 and June 29, 2013.
	The condensed consolidated financial statements and notes are presented as permitted by Form 10-Q and do not contain certain information included in the Company’s annual consolidated financial statements and notes. The information included in this Form 10-Q should be read in conjunction with Management’s Discussion and Analysis and consolidated financial statements and notes thereto included in the Company’s Form 10-K for the year ended December 31, 2013. The results of operations for the three and six months ended June 28, 2014 are not necessarily indicative of the results to be expected for the full year.
Recent Accounting Pronouncements	'
	Recent Accounting Pronouncements
	In May 2014, the FASB issued Accounting Standards Update No. 2014-09, Revenue from Contracts with Customers (Topic 606)(ASU 2014-09). ASU 2014-09 outlines a new, single comprehensive model for entities to use in accounting for revenue arising from contracts with customers and supersedes most current revenue recognition guidance, including industry-specific guidance. This new revenue recognition model provides a five-step analysis in determining when and how revenue is recognized. The new model will require revenue recognition to depict the transfer of promised goods or services to customers in an amount that reflects the consideration a company expects to receive in exchange for those goods or services. ASU 2014-09 is effective for the quarter ending March 31, 2017. The Company is currently assessing the impact that adopting this new accounting guidance will have on its consolidated financial statements and disclosures.
	Other Accounting Standards Updates issued but not effective for the Company until after June 28, 2014 are not expected to have a material effect on the Company’s condensed consolidated financial statements.
