Basis of Presentation and Principles of Consolidation	AMPHENOL CORPORATION NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (Unaudited) (amounts in millions, except share and per share data) Note 1—Basis of Presentation and Principles of Consolidation The condensed consolidated balance sheets as of March 31, 2019 and December 31, 2018, and the related condensed consolidated statements of income, condensed consolidated statements of comprehensive income, and condensed consolidated statements of cash flow for the three months ended March 31, 2019 and 2018 include the accounts of Amphenol Corporation and its subsidiaries ( “Amphenol”, the “Company”, “we”, “our”, or “us” ). 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, 2019 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, 2018 (the “2018 Annual Report”). Net change in accrued pension and postretirement benefits has been presented as a separate line item within cash from operating activities for the prior period in the Company’s Condensed Consolidated Statements of Cash Flow, in order to conform to the current period presentation, which had no impact on our consolidated results of operations, financial position or cash flows. Previously, this item was included within Net change in other long-term assets and liabilities.

New Accounting Pronouncements
New Accounting Pronouncements	Note 2—New Accounting Pronouncements Recently Adopted Accounting Standards Leases In February 2016, the Financial Accounting Standards Board (the “FASB”) issued Accounting Standards Update (“ASU”) No. 2016-02, Leases (Topic 842) (“Topic 842”), which amended, among other things, the existing guidance by requiring lessees to recognize lease right-of-use assets (“ROU assets”) and liabilities arising from operating leases on the balance sheet. Since issuing Topic 842, the FASB has issued various subsequent ASU’s, including but not limited to, ASU 2018-10, Codification Improvements to Topic 842, Leases , which clarified various aspects of the guidance under Topic 842, as well as ASU 2018-11, Leases (Topic 842): Targeted Improvements , which allows entities the option of recognizing the cumulative effect of applying Topic 842 as an adjustment to the opening balance of retained earnings in the year of adoption while continuing to present all prior periods under previous lease accounting guidance. Prior to adoption, the Company evaluated Topic 842, including the initial review of any necessary changes to existing processes and systems that would be required to implement this standard, in order to determine its impact on our consolidated financial statements and related disclosures. In 2018, the Company implemented a new lease management system that facilitated the adoption of this standard and enabled the Company to fulfill its requirements for both reporting and disclosure purposes, as well as to better manage and monitor the Company’s ongoing lease portfolio. The Company ensured all key system functionality and other requirements were met, and we completed our assessment of the standard and implemented the necessary changes to our existing policies, processes and controls to achieve appropriate compliance with regards to our lease portfolio. On January 1, 2019, we adopted Topic 842 using the updated modified retrospective transition approach allowed under ASU 2018-11 and did not restate prior periods. The Company recognized ROU assets and related lease liabilities on our Condensed Consolidated Balance Sheets as of January 1, 2019 of approximately $180 related to our operating lease commitments, and there was no cumulative impact on retained earnings as of January 1, 2019. Topic 842 did not have a material impact on our Condensed Consolidated Statements of Income and Condensed Consolidated Statements of Cash Flow for the three months ended March 31, 2019, nor did it have any impact on our compliance with debt covenants. The adoption of Topic 842 provided various optional practical expedients in transition, some of which we have elected. As part of the adoption, the Company elected the “package of 3” practical expedient, which among other things, permitted us not to reassess the historical lease classifications for existing or expired leases. Going forward, the impact of Topic 842 on the Company’s consolidated financial statements will be dependent upon the Company’s lease portfolio. The accounting for finance leases (formerly referred to as “capital leases”) remains substantially unchanged. Refer to Note 15 herein for further details regarding the impact of the adoption of Topic 842 and other information related to our lease portfolio. Accounting Standards Issued But Not Yet Adopted In August 2018, the FASB issued ASU 2018-13, Fair Value Measurement (Topic 820): Disclosure Framework—Changes to the Disclosure Requirements for Fair Value Measurement (“ASU 2018-13”), which adds, amends and removes certain disclosure requirements related to fair value measurements. Among other changes, this standard requires certain additional disclosure surrounding Level 3 assets, including changes in unrealized gains or losses in other comprehensive income and certain inputs in those measurements. ASU 2018-13 is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2019. Certain amended or eliminated disclosures in this standard may be adopted early, while certain additional disclosure requirements in this standard can be adopted on its effective date. In addition, certain changes in the standard require retrospective adoption, while other changes must be adopted prospectively. The Company is currently evaluating ASU 2018-13 and its impact on our consolidated financial statements.

Revenue Recognition

Revenue Recognition
Revenue Recognition	Note 3—Revenue Recognition Revenues consist of product sales to either end customers and their appointed contract manufacturers (including original equipment manufacturers) or to distributors, and the vast majority of our sales are recognized at a point-in-time under the core principle of recognizing revenue when control transfers to the customer. With limited exceptions, the Company recognizes revenue at the point in time when we ship or deliver the product from our manufacturing facility to our customer, when our customer accepts and has legal title of the goods, and the Company has a present right to payment for such goods. For the three months ended March 31, 2019 and 2018, less than 5% of our net sales are recognized over time, as the associated contracts relate to the sale of goods with no alternative use as they are only sold to a single customer and whose underlying contract terms provide the Company with an enforceable right to payment, including a reasonable profit margin, for performance completed to date, in the event of customer termination. Since we typically invoice our customers at the same time that we satisfy our performance obligations, contract assets and contract liabilities recorded in the Company’s Condensed Consolidated Balance Sheets were not significant as of March 31, 2019 and December 31, 2018. These amounts are recorded in the accompanying Condensed Consolidated Balance Sheets within Other current assets or Other accrued expenses as of March 31, 2019 and December 31, 2018. The Company receives customer orders negotiated with multiple delivery dates that may extend across more than one reporting period until the contract is fulfilled, the end of the order period is reached, or a pre-determined maximum order value has been reached. Orders typically fluctuate from quarter to quarter based on customer demand and general business conditions. It is generally expected that a substantial portion of our remaining performance obligations will be fulfilled within three months, and nearly all of our performance obligations are part of contracts that have original durations of one year or less. Since our performance obligations are generally fulfilled within one year, we have not disclosed the aggregate amount of transaction prices associated with unsatisfied or partially unsatisfied performance obligations as of March 31, 2019. While the Company typically offers standard product warranty coverage which provides assurance that our products will conform to the contractually agreed-upon specifications for a limited period from the date of shipment, the Company’s warranty liabilities and related warranty expense have not been and were not material in the accompanying Condensed Consolidated Financial Statements as of March 31, 2019 and December 31, 2018, and for the three months ended March 31, 2019 and 2018. Disaggregation of Net Sales The following tables show our net sales disaggregated into categories the Company considers meaningful to depict how the nature, amount, timing and uncertainty of revenue and cash flows are affected by economic factors for the three months ended March 31, 2019 and 2018: Three months ended March 31, 2019 Interconnect Cable Products and Products and Total Reportable Assemblies Solutions Business Segments Net sales by: Sales channel: End customers and contract manufacturers $ 1,592.8 $ 72.9 $ 1,665.7 Distributors and resellers 269.9 22.9 292.8 $ 1,862.7 $ 95.8 $ 1,958.5 Geography: United States $ 534.0 $ 44.9 $ 578.9 China 522.4 0.8 523.2 Other foreign locations 806.3 50.1 856.4 $ 1,862.7 $ 95.8 $ 1,958.5 Three months ended March 31, 2018 Interconnect Cable Products and Products and Total Reportable Assemblies Solutions Business Segments Net sales by: Sales channel: End customers and contract manufacturers $ 1,515.6 $ 70.0 $ 1,585.6 Distributors and resellers 254.4 26.9 281.3 $ 1,770.0 $ 96.9 $ 1,866.9 Geography: United States $ 479.2 $ 47.8 $ 527.0 China 527.2 0.8 528.0 Other foreign locations 763.6 48.3 811.9 $ 1,770.0 $ 96.9 $ 1,866.9 Net sales by geographic area are based on the customer location to which the product is shipped.

Reportable Business Segments
Reportable Business Segments	Note 5—Reportable Business Segments The Company has two reportable business segments: (i) Interconnect Products and Assemblies and (ii) Cable Products and Solutions. The Company organizes its reportable business segments based upon similar economic characteristics and business groupings of products, services and customers. These reportable business segments are determined based upon how the Company reviews its businesses, assesses operating performance and makes investing and resource allocation decisions. The Interconnect Product and Assemblies segment primarily designs, manufactures and markets a broad range of connector and connector systems, value-add products and other products, including antennas and sensors, used in a broad range of applications in a diverse set of end markets. The Cable Products and Solutions segment primarily designs, manufactures and markets cable, value-add products and components for use primarily in the broadband communications and information technology markets as well as certain applications in other markets. The accounting policies of the segments are the same as those for the Company as a whole and are described herein and in Note 1 of the notes to the consolidated financial statements in the Company’s 2018 Annual Report. 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. The segment results for the three months ended March 31, 2019 and 2018 are as follows: Interconnect Products Cable Products Total Reportable and Assemblies and Solutions Business Segments Three Months Ended March 31: 2019 2018 2019 2018 2019 2018 Net sales: External $ 1,862.7 $ 1,770.0 $ 95.8 $ 96.9 $ 1,958.5 $ 1,866.9 Intersegment 2.9 2.6 15.7 8.9 18.6 11.5 Segment operating income 410.0 391.1 10.5 11.3 420.5 402.4 A reconciliation of segment operating income to consolidated income before income taxes for the three months ended March 31, 2019 and 2018 is summarized as follows: Three months ended March 31, 2019 2018 Segment operating income $ 420.5 $ 402.4 Interest expense (29.7) (24.5) Other income, net 3.0 2.3 Stock-based compensation expense (14.4) (12.7) Acquisition-related expenses (16.5) — Other operating expenses (13.4) (12.8) Income before income taxes $ 349.5 $ 354.7

During the three months ended March 31, 2018, the Company repurchased 4.2 million shares of its Common Stock for $382.0 under the 2017 Stock Repurchase Program, bringing total repurchases under this program to approximately 12.6 million shares or $1,000.0, thus completing the 2017 Stock Repurchase Program .

The price and timing of any future purchases under the 2018 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, dividends, economic and market conditions and stock price.

Earnings Per Share
Earnings Per Share	Note 7—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 outstanding, which relates to 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, 2019 and 2018 is as follows: Three Months Ended March 31, (dollars and shares in millions, except per share data) 2019 2018 Net income attributable to Amphenol Corporation shareholders $ 267.5 $ 265.6 Basic weighted average common shares outstanding 298.1 303.7 Effect of dilutive stock options 10.5 12.3 Diluted weighted average common shares outstanding 308.6 316.0 Earnings per share attributable to Amphenol Corporation shareholders: Basic $ 0.90 $ 0.87 Diluted $ 0.87 $ 0.84 Excluded from the computations above were anti-dilutive common shares of 6.3 million and nil for the three months ended March 31, 2019 and 2018, respectively.

Commitments and Contingencies
Commitments and Contingencies	Note 8—Commitments and Contingencies The Company has been named as a defendant in several legal actions arising from normal business activities. The Company records a loss contingency liability when a loss is considered probable and the amount can be reasonably estimated. Although the potential liability with respect to certain of such legal actions cannot be reasonably estimated, none of such matters is expected to have a material adverse effect on the Company’s financial condition, results of operations or cash flows. The Company’s legal costs associated with defending itself are recorded to expense as incurred. In August 2018, the Company received a subpoena from the U.S. Department of Defense, Office of the Inspector General, requesting documents pertaining to certain products manufactured by the Company’s Military and Aerospace Group that are purchased or used by the U.S. government. The Company is cooperating with the request. The inquiry remains in the early stages and the Company is unable to estimate the timing or outcome of the matter. 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 adverse effect on the Company’s financial condition, results of operations or cash flows.

In addition, for the three months ended March 31, 2019 and 2018, the Company recognized aggregate income tax benefits of $8.6 and $5.9, respectively, in the provision for income taxes in the accompanying Condensed Consolidated Statements of Income associated with stock-based compensation, which include the excess tax benefits from option exercises of $6.8 and $4.1, respectively. T he impact associated with recognizing excess tax benefits from option exercises in the provision for income taxes on our consolidated financial statements could result in significant fluctuations in our effective tax rate in the future, since the provision for income taxes will be impacted by the timing and intrinsic value of future stock-based compensation award exercises. 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. The expense incurred for stock-based compensation plans is included in Selling, general and administrative expenses in the accompanying Condensed Consolidated Statements of Income. Stock Options In May 2017, the Company adopted the 2017 Stock Purchase and Option Plan for Key Employees of Amphenol and Subsidiaries (the “2017 Employee Option Plan”). A committee of the Company’s Board of Directors has been authorized to grant stock options pursuant to the 2017 Employee Option Plan. The number of shares of the Company’s Class A Common Stock (“Common Stock”) reserved for issuance under the 2017 Employee Option Plan is 30,000,000 shares. As of March 31, 2019, there were 16,982,040 shares of Common Stock available for the granting of additional stock options under the 2017 Employee Option Plan. The Company also continues to maintain the 2009 Stock Purchase and Option Plan for Key Employees of Amphenol and Subsidiaries, as amended (the “2009 Employee Option Plan”). No additional stock options will be granted under the 2009 Employee Option Plan. Options granted under the 2017 Employee Option Plan and the 2009 Employee Option Plan generally vest ratably over a period of five years from the date of grant 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 “2004 Directors Option Plan”). The 2004 Directors Option Plan is administered by the Company’s Board of Directors. The 2004 Directors Option Plan expired in May 2014, except that its terms continue with respect to any outstanding options granted thereunder. Options were last granted under the 2004 Directors Option Plan in May 2011. Options granted under the 2004 Directors Option Plan are fully vested and are generally exercisable over a period of ten years from the date of grant. Stock option activity for the three months ended March 31, 2019 was as follows: Weighted Average Aggregate Weighted Remaining Intrinsic Average Contractual Value Options Exercise Price Term (in years) (in millions) Options outstanding at January 1, 2019 35,550,668 $ 59.77 6.81 $ 798.6 Options granted 40,000 78.12 Options exercised (1,269,121) 37.30 Options forfeited (40,440) 75.17 Options outstanding at March 31, 2019 34,281,107 $ 60.60 6.67 $ 1,160.0 Vested and non-vested options expected to vest at March 31, 2019 32,308,769 $ 59.92 6.59 $ 1,115.4 Exercisable options at March 31, 2019 15,053,947 $ 46.98 5.17 $ 714.4 A summary of the status of the Company’s non-vested options as of March 31, 2019 and changes during the three months then ended is as follows: Weighted Average Fair Value at Options Grant Date Non-vested options at January 1, 2019 19,289,500 $ 9.73 Options granted 40,000 10.48 Options vested (61,900) 8.27 Options forfeited (40,440) 9.74 Non-vested options at March 31, 2019 19,227,160 $ 9.74 During the three months ended March 31, 2019 and 2018, the following activity occurred under the Company’s option plans: Three Months Ended March 31, 2019 2018 Total intrinsic value of stock options exercised $ 70.0 $ 34.3 Total fair value of stock options vested 0.5 0.5 As of March 31, 2019, the total compensation cost related to non-vested options not yet recognized was approximately $127.3 with a weighted average expected amortization period of 3.25 years. The grant-date fair value of each option grant under the 2009 Employee Option Plan, the 2017 Employee Option Plan and the 2004 Directors Option Plan is estimated using the Black-Scholes option pricing model. The grant-date fair value of each share grant is determined based on the closing share price of the Company’s Common 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 Common Stock and implied volatility derived from related exchange traded options. The average expected life is 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 issuances 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. Restricted Shares In 2012, the Company adopted the 2012 Restricted Stock Plan for Directors of Amphenol Corporation (the “2012 Directors Restricted Stock Plan”). The 2012 Directors Restricted Stock Plan is administered by the Company’s Board of Directors. As of March 31, 2019, the number of restricted shares available for grant under the 2012 Directors Restricted Stock Plan was 109,150. Restricted shares granted under the 2012 Directors Restricted Stock Plan generally vest on the first anniversary of the grant date. Grants under the 2012 Directors Restricted Stock Plan entitle the holder to receive shares of the Company’s Common Stock without payment. Restricted share activity for the three months ended March 31, 2019 was as follows: Weighted Average Remaining Restricted Fair Value at Amortization Shares Grant Date Term (in years) Restricted shares outstanding at January 1, 2019 14,873 $ 87.89 0.39 Restricted shares granted — — Restricted shares outstanding at March 31, 2019 14,873 $ 87.89 0.14 As of March 31, 2019, the total compensation cost related to non-vested restricted shares not yet recognized was approximately $0.2 with a weighted average expected amortization period of 0.14 years.

Benefit Plans and Other Postretirement Benefits
Benefit Plans and Other Postretirement Benefits	Note 10—Benefit Plans and Other Postretirement Benefits The Company and certain of its domestic subsidiaries have defined benefit pension plans (the “U.S. Plans”), which cover certain U.S. employees and which represent the majority of the plan 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 “Foreign 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 for the three months ended March 31, 2019 and 2018: Pension Benefits Three Months Ended March 31: 2019 2018 Service cost $ 1.8 $ 1.9 Interest cost 5.4 4.9 Expected return on plan assets (9.2) (9.7) Amortization of prior service cost 0.4 0.6 Amortization of net actuarial losses 4.6 5.9 Net pension expense $ 3.0 $ 3.6 In January 2018, the Company made a voluntary cash contribution of approximately $81.0 to fund the U.S. Plans. This voluntary cash contribution made in the first quarter of 2018 was reflected as cash used in operating activities within Net change in accrued pension and postretirement benefits in the Condensed Consolidated Statements of Cash Flow. The timing and amount of cash contributions in subsequent years will depend on a number of factors, including the investment performance of the Plans’ assets. The Company offers various defined contribution plans for certain U.S. and foreign employees. Participation in these plans is based on certain eligibility requirements. Through 2018, the Company matched the majority of employee contributions to the U.S. defined contribution plans with cash contributions up to a maximum of 5% of eligible compensation. Effective January 1, 2019, the Company increased its matching of employee contributions to the U.S. defined contribution plans to a maximum of 6% of eligible compensation. During the three months ended March 31, 2019 and 2018, the Company provided matching contributions to the U.S. defined contribution plans of approximately $4.0 and $2.3, respectively.

Acquisitions	Note 11—Acquisitions In January 2019, pursuant to a definitive agreement entered into on November 27, 2018, the Company acquired SSI Controls Technologies (“SSI”), the sensor manufacturing division of SSI Technologies, Inc., for approximately $397, net of cash acquired (subject to customary post-closing adjustments), plus a performance-related contingent payment. SSI, which is headquartered in the United States (Wisconsin), is a leading designer and manufacturer of sensors and sensing solutions for the global automotive and industrial markets. The acquisition of SSI is not material to the Company. The contingent consideration payment is based on certain 2019 revenue and profitability levels of SSI. The Company determined the fair value of this liability using Level 3 unobservable inputs, such as probability weighted payout projections, and is classified as Level 3 in the fair value hierarchy (Note 16). The contingent consideration is payable in 2020 and recorded in Other accrued expenses on the accompanying Condensed Consolidated Balance Sheets as of March 31, 2019. In the past twelve months, the Company has completed several other acquisitions, all within the Interconnect Products and Assemblies segment. The Company is in the process of completing its analyses of the fair value of the assets acquired and liabilities assumed. The Company anticipates that the final assessments of values will not differ materially from the preliminary assessments. These acquisitions were not material to the Company either individually or in the aggregate. During the three months ended March 31, 2019, the Company incurred approximately $16.5 ($13.2 after-tax) of acquisition-related expenses, which includes the amortization of $12.5 related to the value associated with acquired backlog from the SSI acquisition, as well as external transaction costs of $4.0. Such acquisition-related expenses are separately presented in the accompanying Condensed Consolidated Statements of Income.

Goodwill and Other Intangible Assets
Goodwill and Other Intangible Assets	Note 12—Goodwill and Other Intangible Assets The changes in the carrying amount of goodwill by segment were as follows: Interconnect Cable Products and Products and Assemblies Solutions Total Goodwill at December 31, 2018 $ 3,956.7 $ 146.5 $ 4,103.2 Acquisition-related 347.1 — 347.1 Foreign currency translation (10.4) — (10.4) Goodwill at March 31, 2019 $ 4,293.4 $ 146.5 $ 4,439.9 The increase in goodwill, net of foreign currency translation, during the first three months of 2019 is primarily due to the acquisition of SSI in January 2019, which is included in the Interconnect Products and Assemblies segment. Other than goodwill noted above, the Company’s intangible assets as of March 31, 2019 and December 31, 2018 were as follows: March 31, 2019 December 31, 2018 Weighted Gross Net Gross Net Average Carrying Accumulated Carrying Carrying Accumulated Carrying Life (years) Amount Amortization Amount Amount Amortization Amount Customer relationships 10 $ 413.8 $ 243.9 $ 169.9 $ 399.2 $ 234.7 $ 164.5 Proprietary technology 11 140.9 63.6 77.3 107.5 60.5 47.0 Backlog and other 2 46.5 46.2 0.3 34.0 33.7 0.3 Total intangible assets (definite-lived) 9 601.2 353.7 247.5 540.7 328.9 211.8 Trade names (indefinite-lived) 186.1 — 186.1 186.1 — 186.1 $ 787.3 $ 353.7 $ 433.6 $ 726.8 $ 328.9 $ 397.9 Intangible assets are included in Intangibles, net and other long-term assets in the accompanying Condensed Consolidated Balance Sheets. The increase in the carrying amounts of intangible assets during the first quarter of 2019 was primarily due to intangible assets acquired as a result of the SSI acquisition. The amortization expense for the three months ended March 31, 2019 and 2018 was approximately $24.8 and $11.9, respectively. The amortization expense during the first three months of 2019 includes $12.5 related to the amortization of acquired backlog. As of March 31, 2019, amortization expense relating to the Company’s current intangible assets estimated for the remainder of 2019 is approximately $35.1 and for each of the next five fiscal years is approximately $41.8 in 2020, $37.1 in 2021, $29.7 in 2022, $27.0 in 2023 and $23.9 in 2024.

The 2019 Revolving Credit Facility, which matures January 2024, increases the lenders’ aggregate commitments by $500.0 and, consistent with the previous 2016 Revolving Credit Facility, gives the Company the ability to borrow at a spread over LIBOR. The Company may utilize the 2019 Revolving Credit Facility for general corporate purposes. At March 31, 2019 and December 31, 2018, there were no borrowings under the 2019 Revolving Credit Facility. The carrying value of any borrowings under the 2019 Revolving Credit Facility would approximate their fair value due primarily to their market interest rates and would be classified as Level 2 in the fair value hierarchy (Note 16). The 2019 Revolving Credit Facility requires payment of certain annual agency and commitment fees and requires that the Company satisfy certain financial covenants. At March 31, 2019, the Company was in compliance with the financial covenants under the 2019 Revolving Credit Facility. Commercial Paper Programs The Company has a commercial paper program pursuant to which the Company issues short-term unsecured commercial paper notes (“U.S. Commercial Paper” or “USCP Notes”) in one or more private placements in the United States (the “U.S. Commercial Paper Program”). The maturities of the USCP Notes vary, but may not exceed 397 days from the date of issue. The USCP Notes are sold under customary terms in the commercial paper market and may be issued at par or a discount therefrom, and bear varying interest rates on a fixed or floating basis. The average interest rate on the U.S. Commercial Paper as of March 31, 2019 was 2.64%. The Amounts available under the Commercial Paper Programs may be borrowed, repaid and re-borrowed from time to time. In conjunction with the 2019 Revolving Credit Facility, the authorization from the Company’s Board of Directors limits the maximum aggregate principal amount outstanding of USCP Notes, ECP Notes, and any other commercial paper, euro-commercial paper or similar programs at any time to $2,500.0. In addition, the maximum aggregate principal amount outstanding of USCP Notes at any time was also increased to $2,500.0. The maximum aggregate principal amount outstanding of ECP Notes at any time remains at $2,000.0. The Commercial Paper Programs are rated A-2 by Standard & Poor’s and P-2 by Moody’s and are currently backstopped by the 2019 Revolving Credit Facility, as amounts undrawn under the Company’s 2019 Revolving Credit Facility are available to repay Commercial Paper, if necessary. Net proceeds of the issuances of the Commercial Paper are expected to be used for general corporate purposes. The Commercial Paper is classified as long-term debt in the accompanying Condensed Consolidated Balance Sheets since the Company has the intent and ability to refinance the Commercial Paper on a long-term basis using the Company’s 2019 Revolving Credit Facility. The Commercial Paper is actively traded and is therefore classified as Level 1 in the fair value hierarchy (Note 16). The carrying value of Commercial Paper borrowings approximates their fair value. U.S. Senior Notes On January 9, 2019, the Company issued $500.0 principal amount of unsecured 4.350% Senior Notes due June 1, 2029 at 99.904% of face value (the “2029 Senior Notes”). The 2029 Senior Notes are unsecured and rank equally in right of payment with the Company’s other unsecured senior indebtedness. Interest on the 2029 Senior Notes is payable semiannually on June 1 and December 1 of each year, commencing on June 1, 2019. The Company may, at its option, redeem some or all of the 2029 Senior Notes at any time by paying 100% of the principal amount, plus accrued and unpaid interest, if any, to the date of repurchase, and if redeemed prior to March 1, 2029, a make-whole premium. In January 2019, the Company used the net proceeds from the 2029 Senior Notes, along with borrowings under the U.S. Commercial Paper Program, to repay $750.0 of 2.55% Senior Notes due in January 2019. All of the Company’s outstanding senior notes in the United States (“U.S. Senior Notes”) are unsecured and rank equally in right of payment with the Company’s other unsecured senior indebtedness. Interest on each series of U.S. Senior Notes is payable semiannually. The Company may, at its option, redeem some or all of any series of U.S. Senior Notes at any time subject to certain terms and conditions, which include paying 100% of the principal amount, plus accrued and unpaid interest, if any, to the date of repurchase and, with certain exceptions, a make-whole premium. The fair value of each series of U.S. Senior Notes is based on recent bid prices in an active market and is therefore classified as Level 1 in the fair value hierarchy (Note 16). The U.S. Senior Notes contain certain financial and non-financial covenants. At March 31, 2019, the Company was in compliance with the financial covenants under its U.S. Senior Notes. Euro Senior Notes On October 8, 2018, the Euro Issuer issued €500.0 (approximately $574.6) principal amount of unsecured 2.000% Senior Notes due October 8, 2028 at 99.498% of face value (the “2028 Euro Notes” or “2.000% Euro Senior Notes”) and collectively with the U.S. Senior Notes, “Senior Notes”). The 2028 Euro Notes are unsecured and rank equally in right of payment with the Euro Issuer’s other unsecured senior indebtedness, and are guaranteed on a senior unsecured basis by the Company. Interest on the 2028 Euro Notes is payable annually on October 8 of each year, commencing on October 8, 2019. The Company may, at its option, redeem some or all of the 2028 Euro Notes at any time by paying 100% of the principal amount, plus accrued and unpaid interest, if any, to the date of repurchase, and if redeemed prior to July 8, 2028, a make-whole premium. The Company used a portion of the net proceeds from the 2028 Euro Notes to repay a portion of the outstanding amounts under its Commercial Paper Programs, with the remainder of the net proceeds being used for general corporate purposes. The 2028 Euro Notes contain certain financial and non-financial covenants . At March 31, 2019, the Company was in compliance with the financial covenants under its 2028 Euro Notes.

Income Taxes	Note 14—Income Taxes Three Months Ended March 31, 2019 2018 Provision for income taxes $ (79.6) $ (86.4) Effective tax rate % % For the three months ended March 31, 2019 and 2018, stock option exercise activity had the impact of lowering our Provision for income taxes by approximately $6.8 and $4.1, respectively, and lowering our effective tax rate by approximately 190 basis points and 110 basis points, respectively, due to the recognition of excess tax benefits within Provision for income taxes in the accompanying Condensed Consolidated Statements of Income. On December 22, 2017, the United States federal government enacted the Tax Cuts and Jobs Act (“Tax Act”), marking a change from a worldwide tax system to a modified territorial tax system in the United States. As part of this change, the Tax Act, among other changes, provides for a transition tax on the accumulated unremitted foreign earnings and profits of the Company’s foreign subsidiaries (“Transition Tax”) and a reduction of the U.S. federal corporate income tax rate from 35% to 21%. The Company finalized its accounting of the Tax Act in the fourth quarter of 2018. The Company will pay its second annual installment of the Transition Tax, net of applicable tax credits and deductions, in the second quarter of 2019, and will pay the balance of the Transition Tax over the remaining eight-year period ending 2025, as permitted under the Tax Act. The current and long-term portions of the Transition Tax are recorded in Accrued income taxes and Other long-term liabilities, respectively, on the Condensed Consolidated Balance Sheets as of March 31, 2019 and December 31, 2018. The Company operates in the U.S. and numerous foreign 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 2014 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 tax authorities and may not be fully sustained, despite the Company’s belief that the underlying tax positions are fully supportable. As of March 31, 2019, the amount of the liability for unrecognized tax benefits, including penalties and interest, which if recognized would impact the effective tax rate, was approximately $140.8, 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 the closing of statutes of limitation. Based on information currently available, management anticipates that over the next twelve-month period, audit activity could be completed and statutes of limitation may close relating to existing unrecognized tax benefits of approximately $37.3

Leases
Leases	Note 15—Leases Amphenol is a lessee of buildings, office space, automobiles and equipment throughout the world, nearly all of which are classified as operating leases expiring at various dates. The Company determines if an arrangement qualifies as a lease at lease inception. The Company adopted Topic 842 effective January 1, 2019. Operating lease liabilities are recorded based on the present value of the future lease payments over the lease term, assessed as of the commencement date. The Company’s real estate leases, which are comprised primarily of manufacturing facilities, warehouses and sales offices, represent the vast majority of our operating lease liabilities and generally have a lease term between 2 and 12 years. The remaining leases consist primarily of machinery and equipment used in production, office equipment and vehicles, each with various lease terms. The vast majority of our leases are comprised of fixed lease payments, with a small percentage of the Company’s real estate leases including lease payments tied to a rate or index which may be subject to variability. Certain real estate leases also include executory costs such as common area maintenance (non-lease component), as well as property insurance and property taxes (non-components). As a practical expedient permitted under Topic 842, we have elected to account for the lease and non-lease components as a single lease component for our real estate leases. Lease payments, which may include lease components, non-lease components and non-components, are included in the measurement of the Company’s lease liabilities to the extent that such payments are either fixed amounts or variable amounts based on a rate or index (fixed in substance) as stipulated in the lease contract. Any actual costs in excess of such amounts are expensed as incurred as variable lease cost. Substantially all of our lease agreements do not specify an implicit borrowing rate, and as such, the Company utilizes its incremental borrowing rate by lease term, in order to calculate the present value of our future lease payments. The discount rate represents a risk-adjusted rate on a secured basis, and is the rate at which the Company would borrow funds to satisfy the scheduled lease liability payment streams commensurate with the lease term. On January 1, 2019, the discount rate used on existing leases at adoption was determined based on the remaining lease term using available data as of that date. For new or renewed leases starting in 2019, the discount rate is determined using available data at lease commencement and based on the lease term including any reasonably certain renewal periods. Some of our lease agreements, primarily related to real estate, include options for the Company to either renew (extend) or early terminate the lease. Leases with renewal options allow the Company to extend the lease term typically between 1 and 6 years. Renewal options are reviewed at lease commencement to determine if such options are reasonably certain of being exercised, which could impact the lease term. When determining if a renewal option is reasonably certain of being exercised, the Company considers several factors, including but not limited to, the significance of leasehold improvements incurred on the property, whether the asset is difficult to replace, or specific characteristics unique to the particular lease that would make it reasonably certain that we would exercise such option. In most cases, the Company has concluded that renewal and early termination options are not reasonably certain of being exercised by the Company (and thus not included in our ROU asset and lease liability) unless there is an economic, financial or business reason to do so. Operating Leases For the three months ended March 31, 2019, total operating lease cost was $24.0, which includes an immaterial amount of variable lease cost, and is recorded in Cost of sales and Selling, general and administrative expenses, dependent on the nature of the leased asset. Other than variable lease cost, operating lease cost is recognized on a straight-line basis over the lease term. The following summarizes: (i) the future minimum undiscounted lease payments under non-cancelable leases for the remainder of 2019 as well as each of the next five years and thereafter, incorporating the practical expedient to account for lease and non-lease components as a single lease component for our existing real estate leases, (ii) a reconciliation of the undiscounted lease payments to the present value of the lease liabilities recognized, and (iii) the lease-related account balances on our Condensed Consolidated Balance Sheets, all as of March 31, 2019: Operating Year Ended December 31, Leases 2019 (excluding the three months ended March 31, 2019) $ 54.2 2020 43.9 2021 29.9 2022 19.4 2023 13.8 2024 10.4 Thereafter 24.4 Total future minimum lease payments $ 196.0 Less imputed interest (15.9) Total present value of future minimum lease payments $ 180.1 As of March 31, 2019 : Operating lease right-of-use assets (included in Intangibles, net and other long-term assets) $ 179.6 Other accrued expenses $ 62.7 Other long-term liabilities 117.4 Total operating lease liabilities $ 180.1 The following summarizes additional supplemental data related to our operating leases: Operating Three Months Ended March 31, 2019 : Leases Supplemental Cash Flow Information: Cash paid for amounts included in the measurement of lease liabilities: Operating cash flows from operating leases $ 21.9 Right-of-use assets obtained in exchange for lease liabilities $ 17.5 As of March 31, 2019 : Weighted Average Remaining Lease Term 5 years Weighted Average Discount Rate 3.4 % Lease contracts that we have executed but which have not yet commenced as of March 31, 2019 were not material, and are excluded from the tables above. The Company does not generally enter into leases involving the construction or design of the underlying asset, and nearly all of the assets we lease are not specialized in nature. Our lease agreements generally do not include residual value guarantees nor do we enter into sublease arrangements with external parties. Prior to January 1, 2019, the Company accounted for its leases in accordance with Topic 840, Leases .

Fair Value Measurements
Fair Value Measurements	Note 16—Fair Value Measurements Fair value is 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, derivative instruments and contingent consideration payments. Substantially all of the Company’s short-term investments consist of certificates of deposit with original maturities of twelve months or less and as such, are considered as Level 1 in the fair value hierarchy as they are traded in active markets for identical assets. The carrying amounts of these instruments, the majority of which are in non-U.S. bank accounts, approximate their fair value. The Company’s derivative instruments represent foreign exchange rate 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 contingent consideration payment related to the SSI acquisition is valued using Level 3 unobservable inputs, such as probability weighted payout projections, within 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, 2019 and December 31, 2018 are as follows: Fair Value Measurements Quoted Prices in Significant Significant Active Markets Observable Unobservable for Identical Inputs Inputs Total Assets (Level 1) (Level 2) (Level 3) March 31, 2019: Short-term investments $ 17.9 $ 17.9 $ — $ — Forward contracts (0.2) — (0.2) — Contingent consideration (75.0) — — (75.0) Total $ (57.3) $ 17.9 $ (0.2) $ (75.0) December 31, 2018: Short-term investments $ 12.4 $ 12.4 $ — $ — Forward contracts 2.4 — 2.4 — Total $ 14.8 $ 12.4 $ 2.4 $ — With the exception of the fair value of the assets acquired and liabilities assumed in connection with acquisition accounting, the Company does not have any other significant financial or non-financial assets and liabilities that are measured at fair value on a non-recurring basis. The amounts recognized in Accumulated other comprehensive income (loss) associated with foreign exchange rate forward contracts and 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 months ended March 31, 2019 and 2018 were not material. The fair values of the forward contracts are recorded within Other current assets, Intangibles, net and other long-term assets, Other accrued expenses or Other long-term liabilities in the accompanying Condensed Consolidated Balance Sheets, depending on their value and remaining contractual period.
