Note 1—Summary of Significant Accounting Policies

Operations

Amphenol Corporation (together with its subsidiaries, “Amphenol” or the “Company”) operates two business segments which consist of manufacturing and selling interconnect products and assemblies, and manufacturing and selling cable products. The Company sells its products to customer locations worldwide.

Use of Estimates

The preparation of consolidated financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Significant estimates and assumptions made by management include the fair value of acquired assets and liabilities, stock-based compensation, pension obligations, gains or losses on derivative instruments, accounting for income taxes, inventories, goodwill and other matters that affect the consolidated financial statements and related disclosures. Actual results could differ from those estimates.

Principles of Consolidation

The consolidated financial statements include the accounts of the Company and its wholly owned and majority owned subsidiaries. All material intercompany balances and transactions have been eliminated in consolidation.

Cash and Cash Equivalents

Cash and cash equivalents consist of cash and liquid investments with an original maturity of less than three months. The carrying amounts approximate fair values of those instruments, the majority of which are in non-U.S. bank accounts.

Short-term Investments

Short-term investments consist primarily of certificates of deposit with original maturities of twelve months or less. The carrying amounts approximate fair values of those instruments, the majority of which are in non-U.S. bank accounts.

Accounts Receivable

Accounts receivable is stated at net realizable value. The Company regularly reviews accounts receivable balances and adjusts the receivable reserves as necessary whenever events or circumstances indicate the carrying value may not be recoverable.

Inventories

Inventories are stated at the lower of standard cost, which approximates average cost, or market. The principal components of cost included in inventories are materials, direct labor and manufacturing overhead. The Company regularly reviews inventory quantities on hand and evaluates the realizability of inventories and adjusts the carrying value as necessary based on forecasted product demand.

Depreciable Assets

Property, plant and equipment are carried at cost less accumulated depreciation. Depreciation is recorded on a straight-line basis over the respective asset lives determined on a composite basis by asset group or on a specific item basis using the estimated useful lives of such assets, which range from 3 to 12 years for machinery and equipment and 20 to 40 years for buildings. Leasehold building improvements are depreciated over the shorter of the lease term or estimated useful life. It is the Company’s policy to periodically review fixed asset lives. Depreciation expense is included in both cost of sales and selling, general and administrative expense in the Consolidated Statements of Income based on the specific categorization and use of the underlying asset being depreciated. The Company assesses the impairment of property and equipment subject to depreciation, whenever events or changes in circumstances indicate the carrying value may not be recoverable. Factors the Company considers important, which could trigger an impairment review, include significant changes in the manner of our use of the asset, significant changes in historical trends in operating performance, significant changes in projected operating performance, and significant negative economic trends. There have been no significant impairments recorded as a result of such reviews during any of the periods presented.

Goodwill

The Company performs its annual evaluation for the impairment of goodwill for the Company’s reporting units as of each June 30. The Company has defined its reporting units as the two reportable business segments “Interconnect Products and Assemblies” and “Cable Products”, as the components of these reportable business segments have similar economic characteristics. In 2012, the Company utilized the option to first assess qualitative factors to determine whether it is necessary to perform the two-step quantitative goodwill impairment test in accordance with ASU 2011-08, Intangibles – Goodwill and Other: Testing for Goodwill Impairment (“ASU 2011-08”), which was adopted by the Company effective January 1, 2012. An entity is not required to calculate the fair value of a reporting unit unless the Company 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. As of June 30, 2012, and for each previous year in which the impairment test has been performed, the estimated fair value of the Company’s reporting units significantly exceeded their carrying values and therefore, the Company has not recognized any goodwill impairment in 2012, 2011 or 2010 in connection with its annual impairment test.

Intangible Assets

Intangible assets are included in other long-term assets and consist primarily of proprietary technology, customer relationships and license agreements and are amortized over the estimated periods of benefit. The Company assesses the impairment of long-lived assets, other than goodwill, including identifiable intangible assets subject to amortization, whenever significant events or significant changes in circumstances indicate the carrying value may not be recoverable. Factors the Company considers important, which could trigger an impairment review, include significant changes in the manner of the use of the asset, changes in historical trends in operating performance, significant changes in projected operating performance, and significant negative economic trends. There have been no impairments recorded during any of the periods presented as a result of such reviews.

Revenue Recognition

The Company’s primary source of revenues is from product sales to its customers. Revenue from sales of the Company’s products is recognized at the time the goods are delivered and title passes, provided the earning process is complete and revenue is measurable. Delivery is determined by the Company’s shipping terms, which are primarily freight on board (“FOB”) shipping point. Revenue is recorded at the net amount to be received after deductions for estimated discounts, allowances and returns. These estimates and related reserves are determined and adjusted as needed based upon historical experience, contract terms and other related factors.

The shipping costs for the majority of the Company’s sales are paid directly by the Company’s customers. In the broadband communications market (approximately 8% of consolidated sales in 2012), the Company pays for shipping costs to the majority of its customers. Shipping costs are also paid by the Company for certain customers in the Interconnect Products and Assemblies segment. Amounts billed to customers related to shipping costs are immaterial and are included in net sales. Shipping costs incurred to transport products to the customer which are not reimbursed are included in selling, general and administrative expense.

Retirement Pension Plans

Costs for retirement pension plans include current service costs and amortization of prior service costs over the average working life expectancy. It is the Company’s policy to fund current pension costs taking into consideration minimum funding requirements and maximum tax deductible limitations. The expense of retiree medical benefit programs is recognized during the employees’ service with the Company as well as amortization of a transition obligation previously recognized. The recognition of expense for retirement pension plans and medical benefit programs is significantly impacted by estimates made by management such as discount rates used to value certain liabilities, expected return on assets and future health care costs. The Company uses third-party specialists to assist management in appropriately measuring the expense associated with pension and other post-retirement plan benefits.

Stock-Based Compensation

The Company accounts for its option and restricted share awards based on the fair value of the award at the date of grant and recognizes compensation expense over the service period that the awards are expected to vest. The Company recognizes expense for stock-based compensation with graded vesting on a straight-line basis over the vesting period of the entire award. Stock-based compensation expense includes the estimated effects of forfeitures, and estimates of forfeitures 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 also impact the amount of expense to be recognized in future periods. The Company’s income before income taxes was reduced by $31,412 ($22,709 after tax), $28,679 ($20,720 after tax) and $25,385 ($18,070 after tax) for the years ended December 31, 2012, 2011 and 2010, respectively, related to the expense incurred for stock-based compensation plans, which is included in selling, general and administrative expenses in the accompanying Consolidated Statements of Income.

The fair value of stock options has been estimated at the date of grant using the Black-Scholes option-pricing model with the following weighted-average assumptions:

	2012		2011		2010
Risk free interest rate	0.8	%	1.7	%	2.2	%
Expected life	4.6 years		4.6 years		5.6 years
Expected volatility	30.0	%	28.0	%	33.0	%
Expected dividend yield	0.8	%	0.1	%	0.1	%

Income Taxes

Deferred income taxes are provided for revenue and expenses which are recognized in different periods for income tax and financial statement reporting purposes. At December 31, 2012, the cumulative amount of undistributed earnings of foreign affiliated companies was approximately $2,235,000. Deferred income taxes are not provided on undistributed earnings of foreign affiliated companies as it is the Company’s intention to reinvest these earnings permanently outside the U.S. It is not practicable to estimate the amount of tax that might be payable if undistributed earnings were to be repatriated as there is a significant amount of uncertainty with respect to the tax impact of the remittance of these earnings due to the fact that dividends received from foreign subsidiaries may generate additional foreign tax credits, which could ultimately reduce the U.S. tax cost of the dividend. These uncertainties are further complicated by the significant number of foreign tax jurisdictions involved. Deferred tax assets are regularly assessed for recoverability based on both historical and anticipated earnings levels and a valuation allowance is recorded when it is more likely than not that these amounts will not be recovered. The tax effects of an uncertain tax position taken or expected to be taken in income tax returns are recognized only if it is “more likely than not” to be sustained on examination by the taxing authorities, based on its technical merits as of the reporting date. The tax benefits recognized in the financial statements from such a position are measured based on the largest benefit that has a greater than fifty percent likelihood of being realized upon ultimate settlement. The Company includes estimated interest and penalties related to unrecognized tax benefits in the provision for income taxes.

Foreign Currency Translation

The financial position and results of operations of the Company’s significant foreign subsidiaries are measured using local currency as the functional currency. Assets and liabilities of such subsidiaries have been translated at current exchange rates and related revenues and expenses have been translated at weighted average exchange rates. The aggregate effect of translation adjustments is included as a component of accumulated other comprehensive income (loss) within equity. Transaction gains and losses related to operating assets and liabilities are included in selling, general and administrative expense, and those related to non-operating assets and liabilities are included in other income, net.

Research and Development

Costs incurred in connection with the development of new products and applications are expensed as incurred. Research and development expenses for the creation of new and improved products and processes were $92,480, $88,877 and $77,570, for the years 2012, 2011 and 2010, respectively, and are included in selling, general and administrative expenses.

Environmental Obligations

The Company recognizes the potential cost for environmental remediation activities when site assessments are made, remediation efforts are probable and related amounts can be reasonably estimated; potential insurance reimbursements are not recorded. The Company assesses its environmental liabilities as necessary and appropriate through regular reviews of contractual commitments, site assessments, feasibility studies and formal remedial design and action plans.

Net Income per Common Share

Basic income per common share is based on the net income attributable to Amphenol Corporation for the year divided by the weighted average number of common shares outstanding. Diluted income per common share assumes the exercise of outstanding, dilutive stock options using the treasury stock method.

Derivative Financial Instruments

Derivative financial instruments, which are periodically used by the Company in the management of its interest rate and foreign currency exposures, are accounted for as cash flow hedges. Gains and losses on derivatives designated as cash flow hedges resulting from changes in fair value are recorded in accumulated other comprehensive income (loss), and subsequently reflected in net income in a manner that matches the timing of the actual income or expense of such instruments with the hedged transaction. Any ineffective portion of the change in the fair value of designated hedging instruments is included in the Consolidated Statements of Income.

Recent Accounting Pronouncements

In February 2013, the Financial Accounting Standards Board (“FASB”) issued ASU 2013-02, Reporting of Amounts Reclassified Out of Accumulated Other Comprehensive Income (“ASU 2013-02”). The update requires disclosure of amounts reclassified out of accumulated other comprehensive income by component. In addition, an entity is required to present either on the face of the Consolidated Statements of Income or in the notes, significant amounts reclassified out of accumulated other comprehensive income by the respective line items of net income but only if the amount reclassified is required to be reclassified to net income in its entirety in the same reporting period. For amounts not reclassified in their entirety to net income, an entity is required to cross-reference to other disclosures that provide additional detail about those amounts. ASU 2013-02 is effective prospectively for the Company for annual and interim periods beginning January 1, 2013. The Company does not expect that the adoption of this update will have a material effect on its financial statements.

In September 2011, the FASB issued ASU 2011-08, Intangibles - Goodwill and Other: Testing for Goodwill Impairment (“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, the Company is not required to calculate the fair value of a reporting unit unless the Company 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 was effective for the Company as of January 1, 2012. The Company utilized the option to assess qualitative factors pursuant to this update when performing its 2012 annual impairment assessment. The adoption of this update did not have a material effect on the Company’s financial statements.

In May 2011, the FASB issued ASU No. 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 in accordance 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.
