NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(Unaudited)

(dollars in thousands, except per share data)

Note 1—Basis of Presentation and Principles of Consolidation

The condensed consolidated balance sheets as of March 31, 2013 and December 31, 2012, and the related condensed consolidated statements of income, comprehensive income and cash flow for the three months ended March 31, 2013 and 2012 include the accounts of Amphenol Corporation and its subsidiaries (the “Company”).  All material intercompany balances and transactions have been eliminated in consolidation. The condensed consolidated financial statements included herein are unaudited. In the opinion of management, all adjustments, consisting of normal recurring adjustments, necessary for a fair presentation in conformity with accounting principles generally accepted in the United States of America have been included.  The results of operations for the three months ended March 31, 2013 are not necessarily indicative of the results to be expected for the full year.  These condensed consolidated financial statements and the related notes should be read in conjunction with the consolidated financial statements and notes included in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2012 (the “2012 Annual Report”).

Note 2—New Accounting Pronouncements

In March 2013, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“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 (“ASU 2013-05”), which clarifies preexisting guidance regarding the treatment of cumulative translation adjustments when a parent either sells a part or all of its investment in a foreign entity. ASU 2013-05 is effective for fiscal years beginning after December 15, 2013; however, early adoption is permitted. The Company is currently evaluating the impact this ASU will have on its financial statements.

In February 2013, the FASB issued ASU 2013-02, Reporting of Amounts Reclassified Out of Accumulated Other Comprehensive Income (“ASU 2013-02”). The update requires disclosure of amounts reclassified out of accumulated other comprehensive income by component.  In addition, an entity is required to present either on the face of the Consolidated Statements of Income 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 not 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 was effective prospectively for the Company for the first quarter of 2013. The adoption of this update did not have any effect on the Company’s financial statements for the three months ended March 31, 2013.

Note 3—Inventories

Inventories consist of:

	March 31, 2013		December 31, 2012
Raw materials and supplies	$	239,379	$	243,127
Work in process	264,786		271,669
Finished goods	207,416		218,922
	$	711,581	$	733,718

Note 4—Reportable Business Segments

The Company has two reportable business segments: (i) Interconnect Products and Assemblies and (ii) Cable Products. The Interconnect Products and Assemblies segment produces antennas, connectors and interconnect assemblies primarily for the communications, defense, commercial aerospace, industrial and automotive markets. The Cable Products segment produces coaxial and flat ribbon cable and related products primarily for communication markets, including cable television. The accounting policies of the segments are the same as those for the Company as a whole. The Company evaluates the performance of business units on, among other things, profit or loss from operations before interest, headquarters’ expense allocations, stock-based compensation expense, income taxes, amortization related to certain intangible assets and nonrecurring gains and losses.

7

The segment results for the three months ended March 31, 2013 and 2012 are as follows:

	Interconnect Products and Assemblies				Cable Products				Total
	2013		2012		2013		2012		2013		2012

Segment operating income	213,301		190,859		11,600		10,676		224,901		201,535

A reconciliation of segment operating income to consolidated income before income taxes for the three months ended March 31, 2013 and 2012 is summarized as follows:

	Three months endedMarch 31,
	2013			2012

Other costs, net	(9,971		)	(9,118		)
Income before income taxes	$	194,285		$	173,717

Note 5—Changes in Equity and Noncontrolling Interests

Net income attributable to noncontrolling interests is classified below net income (earnings per share is determined after the impact of the noncontrolling interests’ share in net income of the Company).  In addition, the equity attributable to noncontrolling interests is presented as a separate caption within equity.

A reconciliation of consolidated changes in equity for the three months ended March 31, 2013 is as follows:

Note 6—Earnings Per Share

Basic earnings per share (“EPS”) is computed by dividing net income attributable to Amphenol Corporation by the weighted-average number of common shares outstanding. Diluted EPS is computed by dividing net income attributable to Amphenol Corporation by the weighted-average number of common shares and dilutive common shares issuable upon the exercise of outstanding stock options. A reconciliation of the basic weighted average common shares outstanding to diluted weighted average common shares outstanding for the three months ended March 31, 2013 and 2012 is as follows (dollars in thousands, except per share amounts):

	Three months ended March 31,
	2013		2012
Net income attributable to Amphenol Corporation shareholders	$	153,007	$	126,563
Basic weighted average common shares outstanding	159,738,168		162,861,863
Effect of dilutive stock options	2,974,834		2,493,275
Diluted weighted average common shares outstanding	162,713,002		165,355,138
Earnings per share attributable to Amphenol Corporation shareholders:
Basic	$	0.96	$	0.78
Diluted	$	0.94	$	0.77

Excluded from the computations above were anti-dilutive stock options of 1,263,518 and 4,185,293 for the three months ended March 31, 2013 and 2012, respectively.

Note 7—Commitments and Contingencies

The Company and its subsidiaries have been named as defendants in several legal actions in which various amounts are claimed arising from normal business activities.  Although the amount of any ultimate liability with respect to such matters cannot be precisely determined, in the opinion of management, such matters are not expected to have a material effect on the Company’s financial condition, results of operations or cash flows.

Certain operations of the Company are subject to environmental laws and regulations which govern the discharge of pollutants into the air and water, as well as the handling and disposal of solid and hazardous wastes. The Company believes that its operations are currently in substantial compliance with applicable environmental laws and regulations and that the costs of continuing compliance will not have a material effect on the Company’s financial condition, results of operations or cash flows.

Subsequent to the acquisition of Amphenol from Allied Signal Corporation (“Allied Signal”) in 1987 (Allied Signal merged with Honeywell International Inc. in December 1999 (“Honeywell”)), the Company and Honeywell were named jointly and severally liable as potentially responsible parties in connection with several environmental cleanup sites. The Company and Honeywell jointly consented to perform certain investigations and remediation and monitoring activities at two sites, the “Route 8” landfill and the “Richardson Hill Road” landfill, and they were jointly ordered to perform work at another site, the “Sidney” landfill. The costs incurred relating to these three sites are currently reimbursed by Honeywell based on an agreement (the “Honeywell Agreement”) entered into in connection with the acquisition in 1987. The environmental investigation, remediation and monitoring activities identified by the Company, including those referred to above, are covered under the Honeywell Agreement.  Management does not believe that the costs associated with resolution of these or any other environmental matters will have a material effect on the Company’s consolidated financial condition, results of operations or cash flows.

Note 8—Stock-Based Compensation

In May 2009, the Company adopted the 2009 Stock Purchase and Option Plan (the “2009 Option Plan”) for Key Employees of the Company and its subsidiaries.  The Company continues to maintain the 2000 Stock Purchase and Option Plan (the “2000 Option Plan”).  No additional options can be granted under the 2000 Option Plan.  The 2009 Option Plan authorizes the granting of additional stock options by a committee of the Company’s Board of Directors. As of March 31, 2013, there were 5,026,370 shares of common stock available for the granting of additional stock options under the 2009 Option Plan. Options granted under the 2000 Option Plan and the 2009 Option Plan generally vest ratably over a period of five years and are generally exercisable over a period of ten years from the date of grant.

In 2004, the Company adopted the 2004 Stock Option Plan for Directors of Amphenol Corporation (the “Directors Option Plan”). The Directors Option Plan is administered by the Company’s Board of Directors.  As of March 31, 2013, the maximum number of shares of common stock available for the granting of additional stock options under the Directors Option Plan was 70,000, although no additional options are expected to be granted under this plan.  Options granted under the Directors Option Plan generally vest ratably over a period of three years and are generally exercisable over a period of ten years from the date of grant.

9

In May 2012, the Company adopted the 2012 Restricted Stock Plan for Directors of Amphenol Corporation (the “Directors Restricted Stock Plan”). The Directors Restricted Stock Plan is administered by the Company’s Board of Directors.  As of March 31, 2013, the maximum number of restricted shares available for grants under the Directors Restricted Stock Plan was 107,955.  Restricted shares granted under the Directors Restricted Stock Plan generally vest on the first anniversary of the grant date.  Grants under the Directors Restricted Stock Plan entitle the holder to receive shares of the Company’s common stock without payment.

The grant-date fair value of each option grant under the 2000 Option Plan, the 2009 Option Plan and the Directors Option Plan is estimated using the Black-Scholes option pricing model. The grant-date fair value of each restricted share grant is determined based on the closing share price of the Company’s stock on the date of the grant. The fair value is then amortized on a straight-line basis over the requisite service period of the awards, which is generally the vesting period. Use of a valuation model for option grants requires management to make certain assumptions with respect to selected model inputs. Expected share price volatility is calculated based on the historical volatility of the stock of the Company and implied volatility derived from related exchange traded options. The average expected life was based on the contractual term of the option and expected exercise and historical post-vesting termination experience. The risk-free interest rate is based on U.S. Treasury zero-coupon issues with a remaining term equal to the expected life assumed at the date of grant. The expected annual dividend per share is based on the Company’s dividend rate.

Stock-based compensation expense includes the estimated effects of forfeitures, which are adjusted over the requisite service period to the extent actual forfeitures differ or are expected to differ from such estimates.  Changes in estimated forfeitures are recognized in the period of change and impact the amount of expense to be recognized in future periods.  For the three months ended March 31, 2013, the Company’s income before income taxes and net income were reduced for stock-based compensation expense by $8,283 and $6,031, respectively.  For the three months ended March 31, 2012, the Company’s income before income taxes and net income were reduced for stock-based compensation expense by $7,491 and $5,353, respectively. The expense incurred for stock-based compensation is included in selling, general and administrative expense in the accompanying Condensed Consolidated Statements of Income.

Stock option activity for the three months ended March 31, 2013 was as follows:

	Options		Weighted Average Exercise Price		Weighted Average Remaining Contractual Term (in years)	Aggregate Intrinsic Value

As of March 31, 2013, the total compensation cost related to non-vested options not yet recognized is approximately $68,292 with a weighted average expected amortization period of 3.08 years.

Restricted Shares

As of March 31, 2013, the Company has issued 17,045 restricted shares with a weighted-average fair value at grant date of $53.78 per share.  As of March 31, 2013, the total compensation cost related to non-vested restricted shares not yet recognized was approximately $148 with a weighted average expected amortization period of 0.15 years.

Note 9—Shareholders’ Equity

In January 2013, the Company’s Board of Directors authorized a stock repurchase program under which the Company may repurchase up to 10,000,000 shares of its common stock during the two year period ending January 31, 2015 (the “2013 Stock Repurchase Program”). The price and timing of any such purchases under the 2013 Stock Repurchase Program will depend on factors such as levels of cash generation from operations, the volume of stock option exercises by employees, cash requirements for acquisitions, economic and market conditions and stock price.  During the three months ended March 31, 2013, the Company repurchased 1,243,561 shares of its common stock for approximately $85,300.  These treasury shares have been or will be retired by the Company and common stock and accumulated earnings were reduced accordingly.

After declaration by the Board of Directors, the Company generally pays a quarterly dividend on its common stock.  In January 2013, the Board of Directors approved the first quarter 2013 dividend on the Company’s common stock in the amount of $0.105 per share.  For the three months ended March 31, 2013, the Company paid dividends in the amount of nil and declared dividends in the amount of $16,755.  For the three months ended March 31, 2012, the Company paid dividends in the amount of $2,448 and declared dividends in the amount of $17,049.

Note 10—Benefit Plans and Other Postretirement Benefits

The Company and certain of its domestic subsidiaries have two defined benefit pension plans (the “U.S. Plans”), which cover its U.S. employees and which represent the majority of the assets and benefit obligations of the aggregate defined benefit plans of the Company. The U.S. Plans’ benefits are generally based on years of service and compensation and are generally noncontributory.  Certain U.S. employees not covered by the U.S. Plans are covered by defined contribution plans.  Certain foreign subsidiaries have defined benefit plans covering their employees (the “International Plans” and, together with the U.S. Plans, the “Plans”). The following is a summary, based on the most recent actuarial valuations of the Company’s net cost for pension benefits, of the Plans and other postretirement benefits for the three months ended March 31, 2013 and 2012.

	Pension Benefits						Other Postretirement Benefits
	Three months ended March 31,
	2013			2012			2013		2012
Service cost	$	2,112		$	1,945		$	40	$	45

Net pension expense	$	7,489		$	6,303		$	360	$	472

11

For the three months ended March 31, 2013, the Company did not make a cash contribution to the U.S. Plans and estimates that, based on current actuarial calculations, it will make aggregate cash contributions to the Plans in 2013 of approximately $21,000, the majority of which will be to the U.S. Plans.  The timing and amount of cash contributions in subsequent years will depend on a number of factors, including the investment performance of the Plan assets.

The Company offers various defined contribution plans for U.S. and foreign employees. Participation in these plans is based on certain eligibility requirements. The Company matches the majority of employee contributions to U.S. defined contribution plans with cash contributions up to a maximum of 5% of eligible compensation.  During the three months ended March 31, 2013 and 2012, the total matching contributions to these U.S. defined contribution plans were approximately $830 and $725, respectively.

Note 11—Goodwill and Other Intangible Assets

As of March 31, 2013, the Company has goodwill totaling $1,919,929, of which $1,804,515 is related to the Interconnect Products and Assemblies segment with the remainder related to the Cable Products segment.  For the three months ended March 31, 2013, goodwill decreased by $12,811, primarily as a result of currency translation.

The Company’s intangible assets are subject to amortization except for goodwill. A summary of the Company’s amortizable intangible assets as of March 31, 2013 and December 31, 2012 is as follows:

	March 31, 2013				December 31, 2012
	Gross Carrying Amount		Accumulated Amortization		Gross Carrying Amount		Accumulated Amortization
Customer relationships	$	166,000	$	57,800	$	166,800	$	54,000
Proprietary technology	44,200		19,700		44,200		18,800
License agreements	6,000		5,500		6,000		5,300
Trade names and other	9,400		7,800		9,400		7,700
Total	$	225,600	$	90,800	$	226,400	$	85,800

Customer relationships, proprietary technology, license agreements and trade names and other amortizable intangible assets have weighted average useful lives of approximately 10 years, 13 years, 8 years and 15 years, respectively, for an aggregate weighted average useful life of approximately 10 years.

Intangible assets are included in other long-term assets in the accompanying Condensed Consolidated Balance Sheets.  The amortization expense for the three months ended March 31, 2013 and 2012 was approximately $5,000 and $4,500, respectively.  As of March 31, 2013, amortization expense estimated for each of the next five fiscal years is approximately $19,300 in 2013, $17,400 in 2014, $16,900 in 2015, $16,100 in 2016, and $15,900 in 2017.

Note 12—Debt

Revolving Credit Facility

The Company has a $1,000,000 unsecured credit facility (the “Revolving Credit Facility”) with a maturity date of July 2016. At March 31, 2013, borrowings and availability under the Revolving Credit Facility were $491,000 and $509,000, respectively.  As of March 31, 2013, the interest rate on borrowings under the Revolving Credit Facility was at a spread over LIBOR. The Revolving Credit Facility requires payment of certain annual agency and commitment fees and requires that the Company satisfy certain financial covenants.  At March 31, 2013, the Company was in compliance with the financial covenants under the Revolving Credit Facility.

Senior Notes

In November 2009, the Company issued $600,000 principal amount of unsecured 4.75% Senior Notes due November 2014 (the “4.75% Senior Notes”) at 99.813% of their face value. Net proceeds from the sale of the 4.75% Senior Notes were used to repay borrowings under the Company’s Revolving Credit Facility. Interest on the 4.75% Senior Notes is payable semi-annually on May 15 and November 15 of each year to the holders of record as of the immediately preceding May 1 and November 1. The Company may, at its option, redeem some or all of the 4.75% Senior Notes at any time by paying a make-whole premium, plus accrued and unpaid interest, if any, to the date of repurchase.  The 4.75% Senior Notes are unsecured and rank equally in right of payment with the Company’s other unsecured senior indebtedness. The fair value of the 4.75% Senior Notes at March 31, 2013 was approximately $635,000 based on recent bid prices in an active market and are therefore classified as Level 1 in the fair value hierarchy.

12

In January 2012, the Company issued $500,000 principal amount of unsecured 4.00% Senior Notes due February 2022 (the “4.00% Senior Notes”) at 99.746% of their face value.  Net proceeds from the sale of the 4.00% Senior Notes before payment of fees and expenses related to the offering in the amount of $498,730 were used to repay borrowings under the Company’s Revolving Credit Facility.  Interest on the 4.00% Senior Notes is payable semi-annually on February 1 and August 1 of each year, to the holders of record as of the immediately preceding January 15 and July 15.  The Company may, at its option, redeem some or all of the 4.00% Senior Notes at any time by paying 100% of the principal amount, plus accrued and unpaid interest, if any, to the date of repurchase, plus a make-whole premium (if redeemed prior to November 1, 2021). The 4.00% Senior Notes are unsecured and rank equally in right of payment with the Company’s other unsecured senior indebtedness.  The fair value of the 4.00% Senior Notes at March 31, 2013 was approximately $522,000 based on recent bid prices in an active market and are therefore classified as Level 1 in the fair value hierarchy.

Receivables Securitization Facility

A subsidiary of the Company has entered into a Receivables Securitization Facility with a financial institution whereby the subsidiary can sell an undivided interest of up to $100,000 in a designated pool of qualified accounts receivable (the “Receivables Securitization Facility”). The Company services, administers and collects the receivables on behalf of the purchaser. The Receivables Securitization Facility includes certain covenants and provides for various events of termination.  In January 2013, the Company amended the Receivables Securitization Facility to extend the expiration date to January 2014.  Transfers of receivables are reflected as debt issued in the Company’s Condensed Consolidated Statements of Cash Flow, and the value of the outstanding undivided interest held by investors at December 31, 2012 and March 31, 2013 is accounted for as a secured borrowing and is included in the Company’s Condensed Consolidated Balance Sheets as short-term debt.  At March 31, 2013, borrowings under the Receivables Securitization Facility were $91,900.  Fees incurred in connection with the Receivables Securitization Facility are included in interest expense.

The carrying value of borrowings under the Company’s Revolving Credit Facility and Receivables Securitization Facility approximated their fair value at March 31, 2013 due to their relative short-term maturities and market interest rates and are therefore classified as Level 2 in the fair value hierarchy.

Note 13—Fair Value Measurements

The Company follows the framework within the Fair Value Measurements and Disclosures topic of the Accounting Standards Codification, which requires fair value to be determined based on the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants. These requirements establish market or observable inputs as the preferred source of values. Assumptions based on hypothetical transactions are used in the absence of market inputs. The Company does not have any non-financial instruments accounted for at fair value on a recurring basis.

The valuation techniques required are based upon observable and unobservable inputs. Observable inputs reflect market data obtained from independent sources, while unobservable inputs reflect the Company’s market assumptions. These two types of inputs create the following fair value hierarchy:

Level 1Quoted prices for identical instruments in active markets.

Level 2Quoted prices for similar instruments in active markets; quoted prices for identical or similar instruments in markets that are not active; and model-derived valuations whose inputs are observable or whose significant value drivers are observable.

Level 3Significant inputs to the valuation model are unobservable.

The Company believes that the assets or liabilities subject to such standards with fair value disclosure requirements are derivative instruments.  The Company’s derivative instruments represent forward contracts, which are valued using bank quotations based on market observable inputs such as forward and spot rates and are therefore classified as Level 2 in the fair value hierarchy. The impact of the credit risk related to these financial assets is immaterial.  The fair values of the Company’s financial and non-financial assets and liabilities subject to such standards at March 31, 2013 and December 31, 2012 are as follows:

	Fair Value Measurements at March 31, 2013
	Total			Quoted Prices in Active Markets for IdenticalAssets (Level 1)		Significant Observable Inputs (Level 2)			Significant Unobservable Inputs (Level 3)
Forward contracts	$	(1,451	)	$	—	$	(1,451	)	$	—
Total	$	(1,451	)	$	—	$	(1,451	)	$	—

13

	Fair Value Measurements at December 31, 2012
	Total			Quoted Prices in Active Markets for IdenticalAssets (Level 1)		Significant Observable Inputs (Level 2)			Significant Unobservable Inputs (Level 3)
Forward contracts	$	(6,018	)	$	—	$	(6,018	)	$	—
Total	$	(6,018	)	$	—	$	(6,018	)	$	—

The Company does not have any significant financial or non-financial assets and liabilities that are measured at fair value on a non-recurring basis.

Note 14—Derivative Instruments

The Company is exposed to certain risks related to its ongoing business operations.  The primary risks managed by using derivative instruments are foreign exchange rate risk and interest rate risk. Foreign exchange rate forward contacts were entered into in 2012 to manage the currency exposures on intercompany loans used to fund recent acquisitions. The hedges will terminate in 2013 upon maturity of the respective intercompany loans.

Derivative instruments are required to be recognized as either assets or liabilities at fair value in the Consolidated Balance Sheets. The Company designates foreign exchange rate forward contacts as cash flow hedges.

As of March 31, 2013 and December 31, 2012, the Company had the following derivative activity related to cash flow hedges:

		Fair Value Assets
	Balance Sheet Location	March 31, 2013			December 31, 2012
Derivatives designated as cash flow hedges:
Forward contracts	Other accrued expenses	$	(1,451	)	$	(6,018	)
Total derivatives designated as cash flow hedging instruments		$	(1,451	)	$	(6,018	)

For the three months ended March 31, 2013 and 2012, $(28) and $(262) were recognized in accumulated other comprehensive income (loss) associated with foreign exchange rate forward contracts, respectively.  The amount reclassified from accumulated other comprehensive income (loss) to foreign exchange gain (loss) in the accompanying Condensed Consolidated Statements of Income during the three month periods ended March 31, 2013 and 2012 was not material.

Note 15—Income Taxes

The provision for income taxes for the first quarter of 2013 and 2012 was at an effective rate of 20.9% and 26.8%, respectively.  In the first quarter of 2013, the Company recorded a benefit of $11,300, or $0.07 per diluted common share, resulting from the delay, by the U.S. government, in the reinstatement of certain federal income tax provisions for the year 2012 relating primarily to research and development credits and certain U.S. taxes on foreign income that are part of the tax provisions within the American Taxpayer Relief Act. Such tax provisions were reinstated on January 2, 2013 with retroactive effect to 2012.  Under U.S. GAAP, the related benefit to the Company of $11,300 relating to the 2012 tax year was recorded as a benefit in the first quarter of 2013 at the date of reinstatement; as such, between the fourth quarter of 2012 and the first quarter of 2013, there is no net impact on the Company from an income statement perspective.  Excluding this benefit, the Company’s effective tax rate for the first quarter of 2013 was 26.8%.

The Company is present in over sixty taxable jurisdictions, and at any point in time has numerous audits underway at various stages of completion. With few exceptions, the Company is subject to income tax examinations by tax authorities for the years 2009 and after.  The Company is generally not able to precisely estimate the ultimate settlement amounts or timing until the close of an audit.  The Company evaluates its tax positions and establishes liabilities for uncertain tax positions that may be challenged by local authorities and may not be fully sustained, despite the Company’s belief that the underlying tax positions are fully supportable. As of March 31, 2013, the amount of the liability for unrecognized tax benefits, which if recognized would impact the effective tax rate, was approximately $17,149, the majority of which is included in other long-term liabilities in the accompanying Condensed Consolidated Balance Sheets.  Unrecognized tax benefits are reviewed on an ongoing basis and are adjusted for changing facts and circumstances, including progress of tax audits and closing of statutes of limitations. Based on information currently available, management anticipates that over the next twelve month period, audit activity could be completed and statutes of limitations may close relating to existing unrecognized tax benefits of approximately $5,764.

Item 2.	MANAGEMENT’S DISCUSSION AND ANALYSIS
	OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS
	(dollars in millions, unless otherwise noted, except per share data)

Results of Operations

Three months ended March 31, 2013 compared to the three months ended March 31, 2012

Net sales were $1,079.8 in the first quarter of 2013 compared to $981.6 in the prior year quarter, an increase of 10% in both U.S. dollars and in local currencies and 4% organically (excluding the impact of foreign exchange and acquisitions) over the prior year quarter.  Sales of interconnect products and assemblies in the first quarter of 2013 (approximately 92% of sales) increased 10% in both U.S. dollars and in local currencies compared to the same period in 2012 ($995.9 in 2013 versus $908.0 in 2012).  The sales growth was driven by increases in nearly all of the served markets and was led by mobile devices, commercial aerospace and industrial, with contributions from both organic growth and the Company’s acquisition program.  Sales of cable products in the first quarter of 2013 (approximately 8% of sales) increased 14% in U.S. dollars and 15% in local currencies compared to the same period in 2012 ($83.9 in 2013 versus $73.6 in 2012) due to a 2012 acquisition, which offset lower sales in the traditional cable products.  Cable products sales growth was primarily in the broadband market.

Geographically, sales in the United States in the first quarter of 2013 increased approximately 8%, compared to the same period in 2012 ($349.4 in 2013 versus $322.9 in 2012).  International sales in the first quarter of 2013 increased approximately 11% in both U.S. dollars and local currencies, compared to the same period in 2012 ($730.4 in 2013 versus $658.7 in 2012). The comparatively stronger U.S. dollar for the first quarter of 2013 had the effect of decreasing sales by approximately $2.1, compared to foreign currency translation rates for the same period in 2012.

The gross profit margin percentage was approximately 31.3% for the first quarter of 2013, compared to 31.5% for the first quarter of 2012.  The operating margin for the Interconnect Products and Assemblies segment for the first quarter of 2013 increased by approximately 40 basis points compared to the prior year quarter, primarily reflecting the positive impact of higher volume and cost reduction actions.  The operating margin for the Cable Products segment for the first quarter of 2013 decreased by approximately 70 basis points compared to the prior year quarter, primarily due to a favorable product mix in the prior year quarter.

Selling, general and administrative expenses increased to $130.9 for the first quarter of 2013, compared to $124.0 for the same period in 2012. Selling, general and administrative expenses increased approximately 6% in the first quarter of 2013 over the prior year quarter, compared to a 10% increase in sales and therefore declined as a percentage of sales from 12.6% in 2012 to 12.1% in 2013. The decrease as a percentage of sales relates primarily to cost control actions and product mix.  Administrative expenses increased approximately $3.0 for the first quarter of 2013 compared to the same period in 2012, primarily related to increases in stock-based compensation expense, employee-related benefits and amortization of acquisition related identified intangible assets, and represented approximately 4.4% and 4.6% of sales for the first quarter of 2013 and 2012, respectively.  Research and development expenses increased approximately $2.1 for the first quarter of 2013 compared to the same period in 2012, reflecting increases in expenses for new product development and represented approximately 2.3% of sales for both the first quarter of 2013 and 2012.  Selling and marketing expenses increased approximately $1.8 for the first quarter of 2013 compared to the same period in 2012, primarily related to the increase in sales volume and represented 5.4% and 5.7% of sales for the first quarter of 2013 and 2012, respectively.

Interest expense for the first quarter of 2013 was $15.5, compared to $13.7 for the same period in 2012.  The increases are primarily attributable to higher average debt levels related to the Company’s stock repurchase program and higher average borrowing costs due primarily to the issuance of the 4.00% Senior Notes in January 2012.

Other income, net, increased to $2.8 for the first quarter of 2013, compared to $2.2 for the same period in 2012, primarily related to higher interest income on higher levels of cash, cash equivalents and short-term investments.

The provision for income taxes for the first quarter of 2013 and 2012 was at an effective rate of 20.9% and 26.8%, respectively.  In the first quarter of 2013, the Company recorded a benefit of $11.3, or $0.07 per diluted common share, resulting from the delay, by the U.S. government, in the reinstatement of certain federal income tax provisions for the year 2012 relating primarily to research and development credits and certain U.S. taxes on foreign income that are part of the tax provisions within the American Taxpayer Relief Act. Such tax provisions were reinstated on January 2, 2013 with retroactive effect to 2012.  Under U.S. GAAP, the related benefit to the Company of $11.3 relating to the 2012 tax year was recorded as a benefit in the first quarter of 2013 at the date of reinstatement; as such, between the fourth quarter of 2012 and the first quarter of 2013, there is no net impact on the Company from an income statement perspective.  Excluding this benefit, the Company’s effective tax rate for the first quarter of 2013 was 26.8%.

The Company is present in over sixty taxable jurisdictions, and at any point in time has numerous audits underway at various stages of completion. With few exceptions, the Company is subject to income tax examinations by tax authorities for the years 2009 and after.  The Company is generally not able to precisely estimate the ultimate settlement amounts or timing until the close of an audit.  The Company evaluates its tax positions and establishes liabilities for uncertain tax positions that may be challenged by local authorities and may not be fully sustained, despite the Company’s belief that the underlying tax positions are fully supportable. As of March 31, 2013, the amount of the liability for unrecognized tax benefits, which if recognized would impact the effective tax rate, was approximately $17.1, the majority of which is included in other long-term liabilities in the accompanying Condensed Consolidated Balance Sheets.  Unrecognized tax benefits are reviewed on an ongoing basis and are adjusted for changing facts and circumstances, including progress of tax audits and closing of statutes of limitations. Based on information currently available, management anticipates that over the next twelve month period, audit activity could be completed and statutes of limitations may close relating to existing unrecognized tax benefits of approximately $5.8.

Liquidity and Capital Resources

Cash flow provided by operating activities was $180.3 in the first three months of 2013 compared to $164.2 in the same 2012 period.  The increase in cash flow provided by operating activities for the first three months of 2013 compared to the same 2012 period is primarily due to an increase in net income and a net decrease in other long-term assets and liabilities, offset by a net increase in the components of working capital compared to a net decrease in the prior year quarter.  The components of working capital as presented on the accompanying Condensed Consolidated Statements of Cash Flow increased $12.1 in the first three months of 2013 due primarily to decreases in accounts payable and other accrued liabilities and an increase in other current assets of $49.7, $18.1 and $6.6, respectively, which were partially offset by a decrease in accounts receivable and inventory of $43.8 and $18.6, respectively.  The components of working capital as presented on the accompanying Condensed Consolidated Statements of Cash Flow decreased $9.9 in the first three months of 2012 due primarily to an increase in accounts payable of $21.9, which was partially offset by increases in inventory and other current assets of $6.1 and $2.1, respectively, as well as a decrease in accrued liabilities of $3.2.

The following describes the significant changes in the amounts as presented on the accompanying Condensed Consolidated Balance Sheets at March 31, 2013. Accounts receivable decreased $49.1 to $861.6 primarily reflecting lower sales levels and to a lesser extent translation resulting from the comparatively stronger U.S. dollar at March 31, 2013 compared to December 31, 2012 (“Translation”).  Days sales outstanding was approximately 73 days at March 31, 2013 compared to 72 days at December 31, 2012.  Inventories decreased $22.1 to $711.6 as a result of lower sales levels and Translation.  Inventory days increased from 83 days at December 31, 2012 to 86 days at March 31, 2013.  Other current assets increased $10.6 to $130.6 primarily due to an increase in other receivables and prepaid expenses.  Land and depreciable assets, net, decreased $1.5 to $415.9 primarily due to depreciation of $26.8 and Translation, partially offset by capital expenditures of $29.7.  Goodwill decreased $12.8 to $1,919.9 primarily as a result of Translation. Accounts payable decreased $51.0 to $445.5, primarily as a result of a decrease in purchasing activity during the period. Payable days were 54 at March 31, 2013 compared to 56 at December 31, 2012.  Total accrued expenses decreased $14.4 to $277.3, primarily due to the payment of incentive compensation during the quarter, and lower accrued wages and income taxes, partially offset by the accrual of dividends declared in March 2013 that were paid in April 2013. Other long-term liabilities increased $5.1 to $39.1 primarily due to an increase in deferred tax liabilities.

For the first three months of 2013, cash flow provided by operating activities of $180.3 and proceeds from the exercise of stock options including tax benefits from stock-based payment arrangements of $39.4 were used to fund net repayments under credit facilities of $17.9, purchases of treasury stock of $85.3, capital expenditures (net of disposals) of $28.9, net purchases of short-term investments of $35.3, and payments to shareholders of noncontrolling interests of $1.2, which resulted in an increase in cash and cash equivalents of $44.1.  For the first three months of 2012, cash flow provided by operating activities of $164.2, proceeds from the 4.00% Senior Notes offering of $498.7, proceeds from the exercise of stock options including tax benefits from stock-based payment arrangements of $27.8 and net proceeds from sales of short-term investments of $11.6 were used to fund net repayments on the Revolving Credit Facility of $480.8, purchases of treasury stock of $81.9, capital expenditures (net of disposals) of $30.5, fees and expenses of $4.3 in connection with the issuance of the 4.00% Senior Notes and dividend payments of $2.4, which resulted in an increase in cash and cash equivalents of $105.9.

The Company has a $1,000.0 unsecured credit facility (the “Revolving Credit Facility”) with a maturity date of July 2016. At March 31, 2013, borrowings and availability under the Revolving Credit Facility were $491.0 and $509.0, respectively.  As of March 31, 2013, the interest rate on borrowings under the Revolving Credit Facility was at a spread over LIBOR. The Revolving Credit Facility requires payment of certain annual agency and commitment fees and requires that the Company satisfy certain financial covenants.  At March 31, 2013, the Company was in compliance with the financial covenants under the Revolving Credit Facility.

16

In November 2009, the Company issued $600.0 principal amount of unsecured 4.75% Senior Notes due November 2014 (the “4.75% Senior Notes”) at 99.813% of their face value. Net proceeds from the sale of the 4.75% Senior Notes were used to repay borrowings under the Company’s Revolving Credit Facility. Interest on the 4.75% Senior Notes is payable semi-annually on May 15 and November 15 of each year to the holders of record as of the immediately preceding May 1 and November 1. The Company may, at its option, redeem some or all of the 4.75% Senior Notes at any time by paying a make-whole premium, plus accrued and unpaid interest, if any, to the date of repurchase.  The 4.75% Senior Notes are unsecured and rank equally in right of payment with the Company’s other unsecured senior indebtedness. The fair value of the 4.75% Senior Notes at March 31, 2013 was approximately $635.0 based on recent bid prices.

In January 2012, the Company issued $500.0 principal amount of unsecured 4.00% Senior Notes due February 2022 (the “4.00% Senior Notes”) at 99.746% of their face value.  Net proceeds from the sale of the 4.00% Senior Notes before payment of fees and expenses related to the offering in the amount of $498,730 were used to repay borrowings under the Company’s Revolving Credit Facility.  Interest on the 4.00% Senior Notes is payable semi-annually on February 1 and August 1 of each year, to the holders of record as of the immediately preceding January 15 and July 15.  The Company may, at its option, redeem some or all of the 4.00% Senior Notes at any time by paying 100% of the principal amount, plus accrued and unpaid interest, if any, to the date of repurchase, plus a make-whole premium (if redeemed prior to November 1, 2021). The 4.00% Senior Notes are unsecured and rank equally in right of payment with the Company’s other unsecured senior indebtedness.  The fair value of the 4.00% Senior Notes at March 31, 2013 was approximately $522.0 based on recent bid prices.

A subsidiary of the Company has entered into a Receivables Securitization Facility with a financial institution whereby the subsidiary can sell an undivided interest of up to $100.0 in a designated pool of qualified accounts receivable (the “Receivables Securitization Facility”). The Company services, administers and collects the receivables on behalf of the purchaser. The Receivables Securitization Facility includes certain covenants and provides for various events of termination.  In January 2013, the Company amended the Receivables Securitization Facility to extend the expiration date to January 2014.  Transfers of receivables are reflected as debt issued in the Company’s Condensed Consolidated Statements of Cash Flow, and the value of the outstanding undivided interest held by investors at December 31, 2012 and March 31, 2013 is accounted for as a secured borrowing and is included in the Company’s Condensed Consolidated Balance Sheets as short-term debt.  At March 31, 2013, borrowings under the Receivables Securitization Facility were $91.9.  Fees incurred in connection with the Receivables Securitization Facility are included in interest expense.

The carrying value of borrowings under the Company’s Revolving Credit Facility and Receivables Securitization Facility approximated their fair value at March 31, 2013.

The Company’s primary ongoing cash requirements will be for operating and capital expenditures, product development activities, repurchases of its common stock, funding of pension obligations, dividends and debt service.  The Company may also use cash to fund all or part of the cost of acquisitions.  The Company generally pays a quarterly dividend on its common stock.  For the three months ended March 31, 2013, the Company paid dividends in the amount of nil and declared dividends in the amount of $16.8.  For the three months ended March 31, 2012, the Company paid dividends in the amount of $2.4 and declared dividends in the amount of $17.0. The Company’s debt service requirements consist primarily of principal and interest on the Senior Notes, the Revolving Credit Facility and the Receivables Securitization Facility.

The Company’s primary sources of liquidity are internally generated cash flow, the Revolving Credit Facility, the Receivables Securitization Facility and cash, cash equivalents and short-term investments.  The Company expects that ongoing cash requirements will be funded from these sources; however, the Company’s sources of liquidity could be adversely affected by, among other things, a decrease in demand for the Company’s products, a deterioration in certain of the Company’s financial ratios or a deterioration in the quality of the Company’s accounts receivables.  However, management believes that the Company’s cash, cash equivalents and short-term investment position, ability to generate strong cash flow from operations, and availability under its Revolving Credit Facility and its Receivables Securitization Facility will allow it to meet its obligations for the next twelve months.

In January 2013, the Company’s Board of Directors authorized a stock repurchase program under which the Company may repurchase up to 10 million shares of its common stock during the two year period ending January 31, 2015 (the “2013 Stock Repurchase Program”). The price and timing of any such purchases under the 2013 Stock Repurchase Program will depend on factors such as levels of cash generation from operations, the volume of stock option exercises by employees, cash requirements for acquisitions, economic and market conditions and stock price.  During the three months ended March 31, 2013, the Company repurchased 1.2 million shares of its common stock for approximately $85.3.  These treasury shares have been or will be retired by the Company and common stock and accumulated earnings were reduced accordingly.

17

For the three months ended March 31, 2013, the Company did not make a cash contribution to the U.S. defined benefit pension plans and estimates that, based on current actuarial calculations, it will make aggregate cash contributions to its defined benefit pension plans in 2013 of approximately $21.0, the majority of which is to the U.S. defined benefit pension plans.  The timing and amount of cash contributions in subsequent years will depend on a number of factors, including the investment performance of the plan assets.

Environmental Matters

Certain operations of the Company are subject to environmental laws and regulations which govern the discharge of pollutants into the air and water, as well as the handling and disposal of solid and hazardous wastes. The Company believes that its operations are currently in substantial compliance with applicable environmental laws and regulations and that the costs of continuing compliance will not have a material effect on the Company’s financial condition, result of operations or cash flows.

Owners and occupiers of sites containing hazardous substances, as well as generators of hazardous substances, are subject to broad liability under various environmental laws and regulations, including expenditures for cleanup and monitoring costs and potential damages arising out of past disposal activities. Such liability in many cases may be imposed regardless of fault or the legality of the original disposal activity. The Company has performed remediation activities and is currently performing operations and maintenance and monitoring activities at three off-site disposal sites previously utilized by the Company’s facility in Sidney, New York, and others - the Richardson Hill Road landfill, the Route 8 landfill and the Sidney landfill.  Actions at the Richardson Hill Road and Sidney landfills were undertaken subsequent to designation as “Superfund” sites on the National Priorities List under the Comprehensive Environmental Response, Compensation and Liability Act of 1980. The Route 8 landfill was designated as a New York State Inactive Hazardous Waste Disposal Site, with remedial actions taken pursuant to Chapter 6, Section 375-1 of the New York Code of Rules and Regulations. In addition, the Company is currently performing monitoring activities at, and in proximity to, its manufacturing site in Sidney, New York. The Company is also engaged in remediating or monitoring environmental conditions at certain of its other manufacturing facilities and has been named as a potentially responsible party for cleanup costs at other off-site disposal sites.

Subsequent to the acquisition of Amphenol from Allied Signal Corporation (“Allied Signal”) in 1987 (Allied Signal merged with Honeywell International Inc. in December 1999 (“Honeywell”)), the Company and Honeywell were named jointly and severally liable as potentially responsible parties in connection with several environmental cleanup sites. The Company and Honeywell jointly consented to perform certain investigations and remediation and monitoring activities at the Route 8 landfill and the Richardson Hill Road landfill, and they were jointly ordered to perform work at the Sidney landfill, all as referred to above. All of the costs incurred relating to these three sites are currently reimbursed by Honeywell based on an agreement (the “Honeywell Agreement”) entered into in connection with the acquisition in 1987. The environmental investigation, remediation and monitoring activities identified by the Company, including those referred to above, are covered under the Honeywell Agreement.  Management does not believe that the costs associated with resolution of these or any other environmental matters will have a material effect on the Company’s consolidated financial condition, result of operations or cash flows.

Since 1987, the Company has not been identified nor has it been named as a potentially responsible party with respect to any other significant on-site or off-site hazardous waste matters. In addition, the Company believes that its manufacturing activities and disposal practices since 1987 have been in material compliance with applicable environmental laws and regulations. Nonetheless, it is possible that the Company will be named as a potentially responsible party in the future with respect to additional Superfund or other sites. Although the Company is unable to predict with any reasonable certainty the extent of its ultimate liability with respect to any pending or future environmental matters, the Company believes, based upon information currently known by management about the Company’s manufacturing activities, disposal practices and estimates of liability with respect to known environmental matters, that any such liability will not have a material effect on the Company’s consolidated financial condition, result of operations or cash flows.

Safe Harbor Statement

Statements in this Form 10-Q, which are other than historical facts, are intended to be “forward-looking statements” within the meaning of the Securities Exchange Act of 1934, the Private Securities Litigation Reform Act of 1995 and other related laws. While the Company believes such statements are reasonable, the actual results and effects could differ materially from those currently anticipated. Please refer to Part I, Item 1A of the Company’s 2012 Annual Report, for some factors that could cause the actual results to differ from estimates. In providing forward-looking statements, the Company is not undertaking any duty or obligation to update these statements publicly as a result of new information, future events or otherwise.

Item 3.   Quantitative and Qualitative Disclosures About Market Risk

The Company, in the normal course of doing business, is exposed to the risks associated with foreign currency exchange rates and changes in interest rates.  There has been no material change in the Company’s assessment of its sensitivity to foreign currency exchange rate risk since its presentation set forth in Part II, Item 7A “Quantitative and Qualitative Disclosures About Market Risk” in its 2012 Annual Report.  As of March 31, 2013, the Company’s average LIBOR rate was 0.20%.  A 10% change in the LIBOR interest rate at March 31, 2013 would have no material effect on interest expense. The Company does not expect changes in interest rates to have a material effect on income or cash flows in 2013, although there can be no assurances that interest rates will not significantly change.

Item 4.   Controls and Procedures

Under the supervision and with the participation of the Company’s management, including the Company’s Chief Executive Officer and Chief Financial Officer, the Company has evaluated the effectiveness of the design and operation of its disclosure controls and procedures as defined in Rules 13a-15(e) and 15d-15(e) of the Securities Exchange Act of 1934 (the “Exchange Act”) as of the period covered by this report. Based on their evaluation, the Chief Executive Officer and Chief Financial Officer have concluded that these disclosure controls and procedures are effective in providing reasonable assurance that information required to be disclosed by the Company in reports that it files or submits under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in Securities and Exchange Commission rules and forms and such information is accumulated and communicated to management, including the Company’s principal executive and financial officers, to allow timely decisions regarding required disclosure. There has been no change in the Company’s internal controls over financial reporting during its most recent fiscal quarter that has materially affected, or is reasonably likely to materially affect, its internal control over financial reporting.

PART II - OTHER INFORMATION

Item 1.   Legal Proceedings

The Company and its subsidiaries have been named as defendants in several legal actions in which various amounts are claimed arising from normal business activities. Although the amount of any ultimate liability with respect to such matters cannot be precisely determined, in the opinion of management, such matters are not expected to have a material adverse effect on the Company’s financial condition or results of operations.

Item 1A.  Risk Factors

There have been no material changes to the Company’s risk factors as disclosed in Part I, Item 1A of the Company’s 2012 Annual Report.

Item 2.   Unregistered Sales of Equity Securities and Use of Proceeds

Repurchase of Equity Securities

In January 2013, the Company’s Board of Directors authorized a stock repurchase program under which the Company may repurchase up to 10 million shares of its common stock during the two year period ending January 31, 2015 (the “2013 Stock Repurchase Program”). The price and timing of any such purchases under the 2013 Stock Repurchase Program will depend on factors such as levels of cash generation from operations, the volume of stock option exercises by employees, cash requirements for acquisitions, economic and market conditions and stock price.  During the three months ended March 31, 2013, the Company repurchased 1.2 million shares of its common stock for approximately $85.3 million.  These treasury shares have been or will be retired by the Company and common stock and accumulated earnings were reduced accordingly.

Note 2—New Accounting Pronouncements

In March 2013, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“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 (“ASU 2013-05”), which clarifies preexisting guidance regarding the treatment of cumulative translation adjustments when a parent either sells a part or all of its investment in a foreign entity. ASU 2013-05 is effective for fiscal years beginning after December 15, 2013; however, early adoption is permitted. The Company is currently evaluating the impact this ASU will have on its financial statements.

In February 2013, the FASB issued ASU 2013-02, Reporting of Amounts Reclassified Out of Accumulated Other Comprehensive Income (“ASU 2013-02”). The update requires disclosure of amounts reclassified out of accumulated other comprehensive income by component.  In addition, an entity is required to present either on the face of the Consolidated Statements of Income 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 not 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 was effective prospectively for the Company for the first quarter of 2013. The adoption of this update did not have any effect on the Company’s financial statements for the three months ended March 31, 2013.

Goodwill and Other Intangible Assets

Note 11—Goodwill and Other Intangible Assets

As of March 31, 2013, the Company has goodwill totaling $1,919,929, of which $1,804,515 is related to the Interconnect Products and Assemblies segment with the remainder related to the Cable Products segment.  For the three months ended March 31, 2013, goodwill decreased by $12,811, primarily as a result of currency translation.

The Company’s intangible assets are subject to amortization except for goodwill. A summary of the Company’s amortizable intangible assets as of March 31, 2013 and December 31, 2012 is as follows:

	March 31, 2013				December 31, 2012
	Gross Carrying Amount		Accumulated Amortization		Gross Carrying Amount		Accumulated Amortization
Customer relationships	$	166,000	$	57,800	$	166,800	$	54,000

Total	$	225,600	$	90,800	$	226,400	$	85,800

Customer relationships, proprietary technology, license agreements and trade names and other amortizable intangible assets have weighted average useful lives of approximately 10 years, 13 years, 8 years and 15 years, respectively, for an aggregate weighted average useful life of approximately 10 years.

Intangible assets are included in other long-term assets in the accompanying Condensed Consolidated Balance Sheets.  The amortization expense for the three months ended March 31, 2013 and 2012 was approximately $5,000 and $4,500, respectively.  As of March 31, 2013, amortization expense estimated for each of the next five fiscal years is approximately $19,300 in 2013, $17,400 in 2014, $16,900 in 2015, $16,100 in 2016, and $15,900 in 2017.

Note 12—Debt

Revolving Credit Facility

The Company has a $1,000,000 unsecured credit facility (the “Revolving Credit Facility”) with a maturity date of July 2016. At March 31, 2013, borrowings and availability under the Revolving Credit Facility were $491,000 and $509,000, respectively.  As of March 31, 2013, the interest rate on borrowings under the Revolving Credit Facility was at a spread over LIBOR. The Revolving Credit Facility requires payment of certain annual agency and commitment fees and requires that the Company satisfy certain financial covenants.  At March 31, 2013, the Company was in compliance with the financial covenants under the Revolving Credit Facility.

Senior Notes

In November 2009, the Company issued $600,000 principal amount of unsecured 4.75% Senior Notes due November 2014 (the “4.75% Senior Notes”) at 99.813% of their face value. Net proceeds from the sale of the 4.75% Senior Notes were used to repay borrowings under the Company’s Revolving Credit Facility. Interest on the 4.75% Senior Notes is payable semi-annually on May 15 and November 15 of each year to the holders of record as of the immediately preceding May 1 and November 1. The Company may, at its option, redeem some or all of the 4.75% Senior Notes at any time by paying a make-whole premium, plus accrued and unpaid interest, if any, to the date of repurchase.  The 4.75% Senior Notes are unsecured and rank equally in right of payment with the Company’s other unsecured senior indebtedness. The fair value of the 4.75% Senior Notes at March 31, 2013 was approximately $635,000 based on recent bid prices in an active market and are therefore classified as Level 1 in the fair value hierarchy.

In January 2012, the Company issued $500,000 principal amount of unsecured 4.00% Senior Notes due February 2022 (the “4.00% Senior Notes”) at 99.746% of their face value.  Net proceeds from the sale of the 4.00% Senior Notes before payment of fees and expenses related to the offering in the amount of $498,730 were used to repay borrowings under the Company’s Revolving Credit Facility.  Interest on the 4.00% Senior Notes is payable semi-annually on February 1 and August 1 of each year, to the holders of record as of the immediately preceding January 15 and July 15.  The Company may, at its option, redeem some or all of the 4.00% Senior Notes at any time by paying 100% of the principal amount, plus accrued and unpaid interest, if any, to the date of repurchase, plus a make-whole premium (if redeemed prior to November 1, 2021). The 4.00% Senior Notes are unsecured and rank equally in right of payment with the Company’s other unsecured senior indebtedness.  The fair value of the 4.00% Senior Notes at March 31, 2013 was approximately $522,000 based on recent bid prices in an active market and are therefore classified as Level 1 in the fair value hierarchy.

Receivables Securitization Facility

A subsidiary of the Company has entered into a Receivables Securitization Facility with a financial institution whereby the subsidiary can sell an undivided interest of up to $100,000 in a designated pool of qualified accounts receivable (the “Receivables Securitization Facility”). The Company services, administers and collects the receivables on behalf of the purchaser. The Receivables Securitization Facility includes certain covenants and provides for various events of termination.  In January 2013, the Company amended the Receivables Securitization Facility to extend the expiration date to January 2014.  Transfers of receivables are reflected as debt issued in the Company’s Condensed Consolidated Statements of Cash Flow, and the value of the outstanding undivided interest held by investors at December 31, 2012 and March 31, 2013 is accounted for as a secured borrowing and is included in the Company’s Condensed Consolidated Balance Sheets as short-term debt.  At March 31, 2013, borrowings under the Receivables Securitization Facility were $91,900.  Fees incurred in connection with the Receivables Securitization Facility are included in interest expense.

The carrying value of borrowings under the Company’s Revolving Credit Facility and Receivables Securitization Facility approximated their fair value at March 31, 2013 due to their relative short-term maturities and market interest rates and are therefore classified as Level 2 in the fair value hierarchy.

Note 6—Earnings Per Share

Basic earnings per share (“EPS”) is computed by dividing net income attributable to Amphenol Corporation by the weighted-average number of common shares outstanding. Diluted EPS is computed by dividing net income attributable to Amphenol Corporation by the weighted-average number of common shares and dilutive common shares issuable upon the exercise of outstanding stock options. A reconciliation of the basic weighted average common shares outstanding to diluted weighted average common shares outstanding for the three months ended March 31, 2013 and 2012 is as follows (dollars in thousands, except per share amounts):

Fair Value Measurements

Fair Value Measurements

Note 13—Fair Value Measurements

The Company follows the framework within the Fair Value Measurements and Disclosures topic of the Accounting Standards Codification, which requires fair value to be determined based on the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants. These requirements establish market or observable inputs as the preferred source of values. Assumptions based on hypothetical transactions are used in the absence of market inputs. The Company does not have any non-financial instruments accounted for at fair value on a recurring basis.

The valuation techniques required are based upon observable and unobservable inputs. Observable inputs reflect market data obtained from independent sources, while unobservable inputs reflect the Company’s market assumptions. These two types of inputs create the following fair value hierarchy:

Level 1 Quoted prices for identical instruments in active markets.

Level 2 Quoted prices for similar instruments in active markets; quoted prices for identical or similar instruments in markets that are not active; and model-derived valuations whose inputs are observable or whose significant value drivers are observable.

Level 3 Significant inputs to the valuation model are unobservable.

The Company believes that the assets or liabilities subject to such standards with fair value disclosure requirements are derivative instruments.  The Company’s derivative instruments represent forward contracts, which are valued using bank quotations based on market observable inputs such as forward and spot rates and are therefore classified as Level 2 in the fair value hierarchy. The impact of the credit risk related to these financial assets is immaterial.  The fair values of the Company’s financial and non-financial assets and liabilities subject to such standards at March 31, 2013 and December 31, 2012 are as follows:

	Fair Value Measurements at March 31, 2013

Shareholders' Equity

Note 9—Shareholders’ Equity

In January 2013, the Company’s Board of Directors authorized a stock repurchase program under which the Company may repurchase up to 10,000,000 shares of its common stock during the two year period ending January 31, 2015 (the “2013 Stock Repurchase Program”). The price and timing of any such purchases under the 2013 Stock Repurchase Program will depend on factors such as levels of cash generation from operations, the volume of stock option exercises by employees, cash requirements for acquisitions, economic and market conditions and stock price.  During the three months ended March 31, 2013, the Company repurchased 1,243,561 shares of its common stock for approximately $85,300.  These treasury shares have been or will be retired by the Company and common stock and accumulated earnings were reduced accordingly.

After declaration by the Board of Directors, the Company generally pays a quarterly dividend on its common stock.  In January 2013, the Board of Directors approved the first quarter 2013 dividend on the Company’s common stock in the amount of $0.105 per share.  For the three months ended March 31, 2013, the Company paid dividends in the amount of nil and declared dividends in the amount of $16,755.  For the three months ended March 31, 2012, the Company paid dividends in the amount of $2,448 and declared dividends in the amount of $17,049.

The Company and its subsidiaries have been named as defendants in several legal actions in which various amounts are claimed arising from normal business activities.  Although the amount of any ultimate liability with respect to such matters cannot be precisely determined, in the opinion of management, such matters are not expected to have a material effect on the Company’s financial condition, results of operations or cash flows.

Certain operations of the Company are subject to environmental laws and regulations which govern the discharge of pollutants into the air and water, as well as the handling and disposal of solid and hazardous wastes. The Company believes that its operations are currently in substantial compliance with applicable environmental laws and regulations and that the costs of continuing compliance will not have a material effect on the Company’s financial condition, results of operations or cash flows.

Subsequent to the acquisition of Amphenol from Allied Signal Corporation (“Allied Signal”) in 1987 (Allied Signal merged with Honeywell International Inc. in December 1999 (“Honeywell”)), the Company and Honeywell were named jointly and severally liable as potentially responsible parties in connection with several environmental cleanup sites. The Company and Honeywell jointly consented to perform certain investigations and remediation and monitoring activities at two sites, the “Route 8” landfill and the “Richardson Hill Road” landfill, and they were jointly ordered to perform work at another site, the “Sidney” landfill. The costs incurred relating to these three sites are currently reimbursed by Honeywell based on an agreement (the “Honeywell Agreement”) entered into in connection with the acquisition in 1987. The environmental investigation, remediation and monitoring activities identified by the Company, including those referred to above, are covered under the Honeywell Agreement.  Management does not believe that the costs associated with resolution of these or any other environmental matters will have a material effect on the Company’s consolidated financial condition, results of operations or cash flows.

Stock-Based Compensation

Note 8—Stock-Based Compensation

In May 2009, the Company adopted the 2009 Stock Purchase and Option Plan (the “2009 Option Plan”) for Key Employees of the Company and its subsidiaries.  The Company continues to maintain the 2000 Stock Purchase and Option Plan (the “2000 Option Plan”).  No additional options can be granted under the 2000 Option Plan.  The 2009 Option Plan authorizes the granting of additional stock options by a committee of the Company’s Board of Directors. As of March 31, 2013, there were 5,026,370 shares of common stock available for the granting of additional stock options under the 2009 Option Plan. Options granted under the 2000 Option Plan and the 2009 Option Plan generally vest ratably over a period of five years and are generally exercisable over a period of ten years from the date of grant.

In 2004, the Company adopted the 2004 Stock Option Plan for Directors of Amphenol Corporation (the “Directors Option Plan”). The Directors Option Plan is administered by the Company’s Board of Directors.  As of March 31, 2013, the maximum number of shares of common stock available for the granting of additional stock options under the Directors Option Plan was 70,000, although no additional options are expected to be granted under this plan.  Options granted under the Directors Option Plan generally vest ratably over a period of three years and are generally exercisable over a period of ten years from the date of grant.

In May 2012, the Company adopted the 2012 Restricted Stock Plan for Directors of Amphenol Corporation (the “Directors Restricted Stock Plan”). The Directors Restricted Stock Plan is administered by the Company’s Board of Directors.  As of March 31, 2013, the maximum number of restricted shares available for grants under the Directors Restricted Stock Plan was 107,955.  Restricted shares granted under the Directors Restricted Stock Plan generally vest on the first anniversary of the grant date.  Grants under the Directors Restricted Stock Plan entitle the holder to receive shares of the Company’s common stock without payment.

The grant-date fair value of each option grant under the 2000 Option Plan, the 2009 Option Plan and the Directors Option Plan is estimated using the Black-Scholes option pricing model. The grant-date fair value of each restricted share grant is determined based on the closing share price of the Company’s stock on the date of the grant. The fair value is then amortized on a straight-line basis over the requisite service period of the awards, which is generally the vesting period. Use of a valuation model for option grants requires management to make certain assumptions with respect to selected model inputs. Expected share price volatility is calculated based on the historical volatility of the stock of the Company and implied volatility derived from related exchange traded options. The average expected life was based on the contractual term of the option and expected exercise and historical post-vesting termination experience. The risk-free interest rate is based on U.S. Treasury zero-coupon issues with a remaining term equal to the expected life assumed at the date of grant. The expected annual dividend per share is based on the Company’s dividend rate.

Stock-based compensation expense includes the estimated effects of forfeitures, which are adjusted over the requisite service period to the extent actual forfeitures differ or are expected to differ from such estimates.  Changes in estimated forfeitures are recognized in the period of change and impact the amount of expense to be recognized in future periods.  For the three months ended March 31, 2013, the Company’s income before income taxes and net income were reduced for stock-based compensation expense by $8,283 and $6,031, respectively.  For the three months ended March 31, 2012, the Company’s income before income taxes and net income were reduced for stock-based compensation expense by $7,491 and $5,353, respectively. The expense incurred for stock-based compensation is included in selling, general and administrative expense in the accompanying Condensed Consolidated Statements of Income.

Benefit Plans and Other Postretirement Benefits

Note 10—Benefit Plans and Other Postretirement Benefits

The Company and certain of its domestic subsidiaries have two defined benefit pension plans (the “U.S. Plans”), which cover its U.S. employees and which represent the majority of the assets and benefit obligations of the aggregate defined benefit plans of the Company. The U.S. Plans’ benefits are generally based on years of service and compensation and are generally noncontributory.  Certain U.S. employees not covered by the U.S. Plans are covered by defined contribution plans.  Certain foreign subsidiaries have defined benefit plans covering their employees (the “International Plans” and, together with the U.S. Plans, the “Plans”). The following is a summary, based on the most recent actuarial valuations of the Company’s net cost for pension benefits, of the Plans and other postretirement benefits for the three months ended March 31, 2013 and 2012.

	Pension Benefits						Other Postretirement Benefits

Net pension expense	$	7,489		$	6,303		$	360	$	472

For the three months ended March 31, 2013, the Company did not make a cash contribution to the U.S. Plans and estimates that, based on current actuarial calculations, it will make aggregate cash contributions to the Plans in 2013 of approximately $21,000, the majority of which will be to the U.S. Plans.  The timing and amount of cash contributions in subsequent years will depend on a number of factors, including the investment performance of the Plan assets.

The Company offers various defined contribution plans for U.S. and foreign employees. Participation in these plans is based on certain eligibility requirements. The Company matches the majority of employee contributions to U.S. defined contribution plans with cash contributions up to a maximum of 5% of eligible compensation.  During the three months ended March 31, 2013 and 2012, the total matching contributions to these U.S. defined contribution plans were approximately $830 and $725, respectively.

Income Taxes

Note 15—Income Taxes

The provision for income taxes for the first quarter of 2013 and 2012 was at an effective rate of 20.9% and 26.8%, respectively.  In the first quarter of 2013, the Company recorded a benefit of $11,300, or $0.07 per diluted common share, resulting from the delay, by the U.S. government, in the reinstatement of certain federal income tax provisions for the year 2012 relating primarily to research and development credits and certain U.S. taxes on foreign income that are part of the tax provisions within the American Taxpayer Relief Act. Such tax provisions were reinstated on January 2, 2013 with retroactive effect to 2012.  Under U.S. GAAP, the related benefit to the Company of $11,300 relating to the 2012 tax year was recorded as a benefit in the first quarter of 2013 at the date of reinstatement; as such, between the fourth quarter of 2012 and the first quarter of 2013, there is no net impact on the Company from an income statement perspective.  Excluding this benefit, the Company’s effective tax rate for the first quarter of 2013 was 26.8%.

The Company is present in over sixty taxable jurisdictions, and at any point in time has numerous audits underway at various stages of completion. With few exceptions, the Company is subject to income tax examinations by tax authorities for the years 2009 and after.  The Company is generally not able to precisely estimate the ultimate settlement amounts or timing until the close of an audit.  The Company evaluates its tax positions and establishes liabilities for uncertain tax positions that may be challenged by local authorities and may not be fully sustained, despite the Company’s belief that the underlying tax positions are fully supportable. As of March 31, 2013, the amount of the liability for unrecognized tax benefits, which if recognized would impact the effective tax rate, was approximately $17,149, the majority of which is included in other long-term liabilities in the accompanying Condensed Consolidated Balance Sheets.  Unrecognized tax benefits are reviewed on an ongoing basis and are adjusted for changing facts and circumstances, including progress of tax audits and closing of statutes of limitations. Based on information currently available, management anticipates that over the next twelve month period, audit activity could be completed and statutes of limitations may close relating to existing unrecognized tax benefits of approximately $5,764.

Derivative Instruments

Note 14—Derivative Instruments

The Company is exposed to certain risks related to its ongoing business operations.  The primary risks managed by using derivative instruments are foreign exchange rate risk and interest rate risk. Foreign exchange rate forward contacts were entered into in 2012 to manage the currency exposures on intercompany loans used to fund recent acquisitions. The hedges will terminate in 2013 upon maturity of the respective intercompany loans.

Derivative instruments are required to be recognized as either assets or liabilities at fair value in the Consolidated Balance Sheets. The Company designates foreign exchange rate forward contacts as cash flow hedges.

As of March 31, 2013 and December 31, 2012, the Company had the following derivative activity related to cash flow hedges:

		Fair Value Assets
	Balance Sheet Location	March 31, 2013			December 31, 2012
Derivatives designated as cash flow hedges:
Forward contracts	Other accrued expenses	$	(1,451	)	$	(6,018	)
Total derivatives designated as cash flow hedging instruments		$	(1,451	)	$	(6,018	)

For the three months ended March 31, 2013 and 2012, $(28) and $(262) were recognized in accumulated other comprehensive income (loss) associated with foreign exchange rate forward contracts, respectively.  The amount reclassified from accumulated other comprehensive income (loss) to foreign exchange gain (loss) in the accompanying Condensed Consolidated Statements of Income during the three month periods ended March 31, 2013 and 2012 was not material.
