Note 1—Basis of Presentation and Principles of Consolidation

The condensed consolidated balance sheets as of March 31, 2012 and December 31, 2011, the related condensed consolidated statements of income for the three months ended March 31, 2012 and 2011, the condensed consolidated statements of comprehensive income for the three months ended March 31, 2012 and 2011, and the condensed consolidated statements of cash flow for the three months ended March 31, 2012 and 2011 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, 2012 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 2011 Annual Report on Form 10-K.

Note 2—New Accounting Pronouncements

In September 2011, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2011-08, Intangibles - Goodwill and Other (“ASU 2011-08”), which allows an entity the option to first assess qualitative factors to determine whether it is necessary to perform the two-step quantitative goodwill impairment test. Under this amendment, an entity is not required to calculate the fair value of a reporting unit unless the entity determines, based on a qualitative assessment of events and circumstances, that it is more likely than not that its fair value is less than its carrying amount. ASU 2011-08 is effective for annual and interim goodwill impairment tests performed for fiscal years beginning after December 15, 2011. The Company will consider this update when performing its annual impairment assessment as of the second quarter of 2012.

In May 2011, the FASB issued ASU 2011-04, Fair Value Measurement: Amendments to Achieve Common Fair Value Measurement and Disclosure Requirements in U.S. GAAP and IFRSs (“ASU 2011-04”). ASU 2011-04 improves comparability of fair value measurements presented and disclosed in financial statements prepared with U.S. generally accepted accounting principles and International Financial Reporting Standards. ASU 2011-04 clarifies the application of existing fair value measurement requirements including (1) the application of the highest and best use and valuation premise concepts, (2) measuring the fair value of an instrument classified in a reporting entity’s shareholders’ equity, and (3) quantitative information required for fair value measurements categorized within Level 3 of the fair value hierarchy. ASU 2011-04 also provides guidance on measuring the fair value of financial instruments managed within a portfolio, and application of premiums and discounts in a fair value measurement. In addition, ASU 2011-04 requires additional disclosure for Level 3 measurements regarding the sensitivity of fair value to changes in unobservable inputs and any interrelationships between those inputs. The amendments in this guidance are to be applied prospectively, and were effective for the Company beginning January 1, 2012. The adoption of this update did not have a material effect on the Company’s financial statements.

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 connectors and connector assemblies primarily for the communications, aerospace, industrial and automotive markets. The Cable Products segment produces coaxial and flat ribbon cable and related products primarily for the communications 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 its business segments on, among other things, profit or loss from operations before interest, income taxes and stock-based compensation expense as well as other costs such as headquarters expense allocations, amortization related to certain intangible assets and nonrecurring gains and losses.

The segment results for the three months ended March 31, 2012 and 2011 are as follows:

A reconciliation of segment operating income to consolidated income before income taxes for the three months ended March 31, 2012 and 2011 is summarized as follows:

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 liability related 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, 2012 is as follows:

A reconciliation of consolidated changes in equity for the three months ended March 31, 2011 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, 2012 and 2011 is as follows (dollars in thousands, except per share amounts):

Excluded from the computations above were anti-dilutive common shares of 4,185,293 and 49,000 for the three months ended March 31, 2012 and 2011, 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 or results of operations.

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 or results of operations.

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. 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. 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 or results of operations. The environmental investigation, remediation and monitoring activities identified by the Company, including those referred to above, are covered under the Honeywell Agreement.

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 currently also maintains 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, 2012, there were 7,788,950 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 vest ratably over a period of five years and are 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, 2012, the maximum number of shares of common stock available for the granting of additional stock options under the Directors Option Plan was 70,000.  Options granted under the Directors Option Plan vest ratably over a period of three years and are exercisable over a period of ten years from the date of grant.

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 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 requires management to make certain assumptions with respect to selected model inputs. Expected share price volatility was 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, 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.  For the three months ended March 31, 2011, the Company’s income before income taxes and net income were reduced for stock-based compensation expense by $6,320 and $4,582, 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, 2012 was as follows:

A summary of the status of the Company’s non-vested options as of March 31, 2012 and changes during the three months then ended is as follows:

During the three months ended March 31, 2012 and 2011, the following activity occurred under the Company’s option plans:

As of March 31, 2012, the total compensation cost related to non-vested options not yet recognized is approximately $66,949 with a weighted average expected amortization period of 3.08 years.

Note 9—Shareholders’ Equity

In January 2011, the Company’s Board of Directors authorized a stock repurchase program under which the Company may repurchase up to 20,000,000 shares of its common stock during the three year period ending January 31, 2014 (the “Program”). During the three months ended March 31, 2012, the Company repurchased 1,495,910 shares of its common stock for approximately $81,885.  These treasury shares have been or will be retired by the Company and common stock and accumulated earnings were reduced accordingly.  Through April 30, 2012, the Company has repurchased an additional 845,000 shares of its common stock for $48,249.  At April 30, 2012, approximately 4,230,700 additional shares of common stock may be repurchased under the Program.

After declaration by the Board of Directors, the Company pays a quarterly dividend on its common stock.  In January 2012, the Board of Directors approved the first quarter 2012 dividend on the Company’s common stock in the amount of $.105 per share.  This represents an increase in the quarterly dividend rate from $.015 to $.105 per share effective with the first quarter 2012 dividend, which was paid in April 2012.  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.  For the three months ended March 31, 2011, the Company paid dividends in the amount of $2,633 and declared dividends in the amount of $2,642.

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 both the U.S. Plans and the International Plans and other postretirement benefits for the three months ended March 31, 2012 and 2011.

For the three months ended March 31, 2012, the Company made cash contributions to the U.S. Plans of $8,800 and estimates that, based on current actuarial calculations, it will make aggregate cash contributions to the Plans in 2012 of approximately $26,000, the majority of which is 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, 2012 and 2011, the total matching contributions to these U.S. defined contribution plans were approximately $725 and $700, respectively.

Note 11—Goodwill and Other Intangible Assets

As of March 31, 2012, the Company has goodwill totaling $1,754,951, of which $1,681,402 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, 2012, goodwill increased by $8,838, 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, 2012 and December 31, 2011 is as follows:

Customer relationships, proprietary technology, license agreements and trade names and other amortizable intangible assets have weighted average useful lives of approximately 10 years, 14 years, 8 years and 15 years, respectively, for an aggregate weighted average useful life of approximately 11 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, 2012 and 2011 was approximately $4,500 and $3,300, respectively.  As of March 31, 2012, amortization expense estimated for each of the next five fiscal years is approximately $17,800 in 2012, $14,600 in 2013, $12,700 in 2014, $12,200 in 2015, and $11,400 in 2016.

Note 12—Debt

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, 2012 was approximately $651,000 based on recent bid prices.

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, beginning August 1, 2012, 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, 2012 was approximately $506,000 based on recent bid prices.

Revolving Credit Facility

In June 2011, the Company amended its $1,000,000 unsecured credit facility (the “Revolving Credit Facility”) to reduce borrowing costs and to extend the maturity date from August 2014 to July 2016. At March 31, 2012, borrowings and availability under the Revolving Credit Facility were $216,000 and $784,000, respectively.  As of March 31, 2012, 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, 2012, the Company was in compliance with the financial covenants under the Revolving Credit Facility.

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 2012, the Company amended the Receivables Securitization Facility to reduce certain fees and amend the expiration date to January 2013.  In accordance with FASB ASU 2009-16, Accounting for Transfers of Financial Assets (“ASU 2009-16”), 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, 2011 and March 31, 2012 is accounted for as a secured borrowing and is included in the Company’s Condensed Consolidated Balance Sheets as long-term debt at December 31, 2011 and short-term debt at March 31, 2012.  At March 31, 2012, borrowings under the Receivables Securitization Facility were $78,000.  Additionally, in accordance with ASU 2009-16, 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, 2012.

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 short-term investments, which are independently valued using market observable Level 1 inputs and derivative instruments, which represent forward contracts which expire in November 2012 and are valued using market observable Level 2 inputs. The Company’s Level 1 short-term investments consist primarily of certificates of deposit with original maturities of twelve months or less. 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, 2012 and December 31, 2011 are as follows:

13

Table of Contents

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 2011 to manage the currency exposure on an intercompany loan used to fund an acquisition. The hedge will terminate in November 2012 upon maturity of the intercompany loan.

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

As of March 31, 2012 and December 31, 2011, the Company had the following derivative activity related to cash flow hedges:

For the three months ended March 31, 2012 and 2011, $(262) and nil was 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 year ended December 31, 2011 was not material.

Note 15—Income Taxes

The provision for income taxes for the first quarter of 2012 and 2011 was at an effective rate of 26.8% and 27.5%, respectively.  The lower income tax rate in 2012 is primarily attributed to a decrease in income in higher tax jurisdictions.

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 2008 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, 2012, the amount of the liability for unrecognized tax benefits, which if recognized would impact the effective tax rate, was approximately $22,535, 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 $3,900.

Results of Operations

Three months ended March 31, 2012 compared to the three months ended March 31, 2011

Net sales were $981.6 in the first quarter of 2012 compared to $940.6 in the prior year quarter, an increase of 4% in U.S. dollars and 5% in local currencies over the prior year quarter and from an organic standpoint (excluding the impact of foreign exchange and acquisitions) sales were comparable to the first quarter of 2011.  Sales of interconnect products and assemblies (approximately 93% of sales) increased 3% in U.S. dollars and 4% in local currencies in the first quarter of 2012 compared to the same period in 2011 ($908.0 in 2012 versus $877.5 in 2011) primarily due to the impact of acquisitions.  In addition, strong organic growth in the automotive, commercial aerospace, industrial and telecommunications and data communications markets was offset by declines in the wireless and military markets. Sales of cable products (approximately 7% of sales) increased 17% in U.S. dollars and 18% in local currencies in the first quarter of 2012 compared to the same period in 2011 ($73.6 in 2012 versus $63.1 in 2011). This increase is primarily due to increases in broadband markets globally.

Geographically, sales in the United States in the first quarter of 2012 were comparable to sales for the same period in 2011 ($322.9 in 2012 versus $323.5 in 2011). International sales for the first quarter of 2012 increased approximately 7% in both U.S. dollars and local currencies compared to the same period in 2011 ($658.7 in 2012 versus $617.1 in 2011) with particular strength in Europe due primarily to acquisitions. The comparatively stronger U.S. dollar for the first quarter of 2012 had the effect of decreasing sales by approximately $4.1 compared to foreign currency translation rates for the same periods in 2011.

The gross profit margin as a percentage of net sales was approximately 31.5% for the first quarter of 2012, compared to 32.3% for the first quarter of 2011.  The operating margins in the Interconnect Products and Assemblies segment decreased approximately 110 basis points in the first quarter of 2012 compared to the same period in 2011, primarily as a result of the impacts of increases in material input costs, partially offset by the positive impacts of cost reduction actions.  The operating margins in the Cable Products segment increased by approximately 270 basis points in the first quarter of 2012 compared to the same period in 2011, primarily as a result of strong volumes and favorable product mix.

Selling, general and administrative expenses increased to $124.0, or 12.6% of net sales, for the first quarter of 2012 compared to $118.0, or 12.5% of net sales for the same period in 2011. The increase in expense in the first quarter of 2012 is primarily attributable to increases in selling expense resulting from higher sales volume, increased research and development spending relating to new product development, higher stock-based compensation expense, and an increase in amortization expense due to recent acquisitions. Selling, general and administrative expenses include stock-based compensation expense of $7.5 for the first quarter of 2012 compared to $6.3 for the same period in 2011.

Interest expense for the first quarter of 2012 was $13.7 compared to $10.0 for the same period in 2011.  The increase for the period is primarily attributable to higher average debt levels related to the Company’s stock repurchase program, and the higher interest expense associated with the Company’s January 2012 4.00% Senior Notes offering.

Other income, net, increased to $2.2 for the first quarter of 2012 compared to $1.7 for the same period in 2011, primarily related to interest income on higher levels of cash, cash equivalents and short-term investments.

The provision for income taxes for the first quarter of 2012 and 2011 was at an effective rate of 26.8% and 27.5%, respectively.  The lower income tax rate in 2012 is primarily attributed to a decrease in income in higher tax jurisdictions.

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 2008 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, 2012, the amount of the liability for unrecognized tax benefits, which if recognized would impact the effective tax rate, was approximately $22.5, 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 $3.9.

Liquidity and Capital Resources

Cash flow provided by operating activities was $164.2 in the first three months of 2012 compared to $107.7 in the same 2011 period.  The increase in cash flow provided by operating activities for the first three months of 2012 compared to the same 2011 period is primarily due to a decrease in the components of working capital. 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 components of working capital increased $44.1 in the first three months of 2011 due primarily to increases in inventory, accounts receivable and other current assets of $46.0, $16.9 and $4.0, respectively, which were partially offset by an increase in accounts payable of $23.8.

The following describes the significant changes in the amounts as presented on the accompanying Condensed Consolidated Balance Sheets at March 31, 2012. Accounts receivable increased $4.2 to $771.4 reflecting higher sales levels and translation resulting from the comparatively stronger U.S. dollar at March 31, 2012 compared to December 31, 2011 (“Translation”). Days sales outstanding was approximately 70 days at March 31, 2012 compared to 71 days at December 31, 2011.  Inventories increased $9.2 to $659.1 to support higher sales levels and were also impacted by Translation.  Inventory days decreased from 89 days at December 31, 2011 to 88 days at March 31, 2012.  Land and depreciable assets, net, increased $9.4 to $389.9 primarily due to capital expenditures of $31.5 and Translation, partially offset by depreciation of $23.6. Goodwill increased $8.8 to $1,755.0 primarily due to Translation. Accounts payable increased $25.0 to $402.9, primarily as a result of an increase in purchasing activity during the period and Translation. Payable days increased from 53 days at December 31, 2011 to 54 days at March 31, 2012.  Total accrued expenses decreased $0.5 to $263.8, primarily due to payment of incentive compensation during the quarter and lower accrued income taxes offset by an increase in dividends payable.  Accrued pension and post-employment benefit obligations increased $0.3 to $207.3, primarily due to pension expense and Translation, offset by contributions of $8.8 to the Company’s U.S. defined benefit pension plan. Other long-term liabilities increased $9.4 to $43.6 primarily due to an increase in deferred tax liabilities and Translation.

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 of $31.5, 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. For the first three months of 2011, cash flow provided by operating activities of $107.7, net borrowings of $149.6 and proceeds from the exercise of stock options including tax benefits from stock-based payment arrangements of $16.5 were used to fund purchases of treasury stock of $188.5, capital expenditures of $23.3 and dividend payments of $2.6, which resulted in an increase in cash and cash equivalents of $67.1.

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, 2012 was approximately $651.0 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 this offering in the amount of $498.7 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, beginning August 1, 2012, 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, 2012 was approximately $506.0 based on recent bid prices.

In June 2011, the Company amended its $1,000.0 unsecured credit facility (the “Revolving Credit Facility”) to reduce borrowing costs and to extend the maturity date from August 2014 to July 2016. At March 31, 2012, borrowings and availability under the Revolving Credit Facility were $216.0 and $784.0, respectively.  As of March 31, 2012, 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, 2012, the Company was in compliance with the financial covenants under the Revolving Credit 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 $100.0 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 2012, the Company amended the Receivables Securitization Facility to reduce certain fees and amend the expiration date to January 2013.  In accordance with FASB ASU 2009-16, Accounting for Transfers of Financial Assets (“ASU 2009-16”), 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, 2011 and March 31, 2012 is accounted for as a secured borrowing and is included in the Company’s Condensed Consolidated Balance Sheets as long-term debt at December 31, 2011 and short-term debt at March 31, 2012.  At March 31, 2012, borrowings under the Receivables Securitization Facility were $78.0.  Additionally, in accordance with ASU 2009-16, 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, 2012.

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 pays a quarterly dividend on its common stock.  In January 2012, the Board of Directors approved the first quarter 2012 dividend on its common stock in the amount of $.105 per share.  This represents an increase in the quarterly dividend rate from $.015 to $.105 per share effective with the first quarter 2012 dividend, which was paid in April 2012. 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.  For the three months ended March 31, 2011, the Company paid and declared dividends in the amount of $2.6. 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 2011, the Company’s Board of Directors authorized a stock repurchase program under which the Company may repurchase up to 20 million shares of its common stock during the three year period ending January 31, 2014 (the “Program”). During the three months ended March 31, 2012, the Company repurchased approximately 1.5 million shares of its common stock for approximately $81.9.  These treasury shares have been or will be retired by the Company and common stock accumulated earnings were reduced accordingly.  Through April 30, 2012, the Company has repurchased an additional 0.8 million shares of its common stock for $48.2.  At April 30, 2012, approximately 4.2 million additional shares of common stock may be repurchased under the Program.

For the three months ended March 31, 2012, the Company made cash contributions to the U.S. Plans of $8.8 and estimates that, based on current actuarial calculations, it will make aggregate cash contributions to the Plans in 2012 of approximately $26.0, the majority of which is 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.

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 or results of operations.

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. 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 or results of operations. The environmental investigation, remediation and monitoring activities identified by the Company, including those referred to above, are covered under the Honeywell Agreement.

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 or results of operations.
