Summary of Significant Accounting Policies

2.   Summary of Significant Accounting Policies

Principles of Consolidation

The consolidated financial statements include the accounts of Molex Incorporated and our majority-owned subsidiaries. All material intercompany balances and transactions are eliminated in consolidation. Equity investments in which we exercise significant influence but do not control and are not the primary beneficiary are accounted for using the equity method. Investments in which we are not able to exercise significant influence over the investee are accounted for under the cost method.

Use of Estimates

The preparation of consolidated financial statements in conformity with accounting principles generally accepted in the United States requires the use of estimates and assumptions related to the reporting of assets, liabilities, net revenue, expenses and related disclosures. Actual results could differ from these estimates. Material subsequent events are evaluated and disclosed through the report issuance date.

Currency Translation

Assets and liabilities of international entities are translated at period-end exchange rates and income and expenses are translated using weighted-average exchange rates for the period. Translation adjustments are included as a component of accumulated other comprehensive income.

Cash and Cash Equivalents

We consider all liquid investments with original maturities of three months or less to be cash equivalents.

Marketable Securities

Marketable securities consist primarily of time deposits held at non-U.S. local banks. We generally hold these instruments for a period of greater than three months, but no longer than 12 months. Marketable securities are classified as available-for-sale securities.

No mark-to-market adjustments were required during fiscal 2011, 2010 or 2009 because the carrying value of the securities approximated the market value. We did not liquidate any available-for-sale securities prior to maturity in fiscal 2011, 2010 and 2009.

Accounts Receivable

In the normal course of business, we extend credit to customers that satisfy pre-defined credit criteria. We believe that we have little concentration of credit risk due to the diversity of our customer base. Accounts receivable, are shown net of allowances and anticipated discounts on the Consolidated Balance Sheets. An allowance for doubtful accounts is determined through analysis of the aging of accounts receivable at the date of the consolidated financial statements, assessments of collectability based on historical trends and an evaluation of the impact of current and projected economic conditions. We monitor the collectability of our accounts receivable on an ongoing basis by analyzing the aging of our accounts receivable, assessing the credit worthiness of our customers and evaluating the impact of reasonably likely changes in economic conditions that may impact credit risks. Our accounts receivable are not collateralized.

Inventories

Inventories are valued at the lower of first-in, first-out cost or market value.

Property, Plant and Equipment

Property, plant and equipment are reported at cost less accumulated depreciation. Depreciation is primarily recorded on a straight-line basis for consolidated financial statement reporting purposes and using a combination of accelerated and straight-line methods for tax purposes.

The estimated useful lives are as follows:

Buildings	25 — 40 years
Machinery and equipment	3 — 10 years
Molds and dies	3 — 4 years

We perform reviews for impairment of long-lived assets whenever adverse events or circumstances indicate that the carrying value of an asset may not be recoverable. When indicators of impairment are present, we evaluate the carrying value of the long-lived assets in relation to the operating performance and future undiscounted cash flows of the underlying assets. We adjust the net book value of the underlying assets to fair value if the sum of the expected undiscounted future cash flows is less than book value.

Goodwill

Goodwill is recorded when the purchase price paid for an acquisition exceeds the estimated fair value of the net identified tangible and intangible assets acquired. We perform an annual review in the fourth quarter of each year, or more frequently if indicators of potential impairment exist, to determine if the carrying value of the recorded goodwill is impaired. The impairment review process compares the fair value of the reporting unit in which goodwill resides to its carrying value. Reporting units may be operating segments as a whole or an operation one level below an operating segment, referred to as a component.

Our goodwill impairment reviews require a two-step process. The first step of the review compares the estimated fair value of the reporting unit against its aggregate carrying value, including goodwill. We estimate the fair value of our segments using the income and market methods of valuation, which includes the use of estimated discounted cash flows. Based on this analysis, if we determine the carrying value of the segment exceeds its fair value, then we complete the second step to determine the fair value of net assets in the segment and quantify the amount of goodwill impairment.

Other-Than-Temporary Impairments (OTTI)

For available-for-sale securities, we presume an OTTI decline in value if the quoted market price of the security is 20% or more below the investment’s cost basis for a continuous period of six months or more. However, the presumption of an OTTI decline in value may be overcome if there is persuasive evidence indicating that the decline is temporary in nature. For investments accounted for under the equity method, we evaluate all known quantitative and qualitative factors in addition to quoted market prices in determining whether an OTTI decline in value exists. Factors that we consider important in evaluating whether a potential OTTI exists, include historical operating performance, future financial projections, business plans for new products or concepts and strength of balance sheet.

Pension and Other Postretirement Plan Benefits

Pension and other postretirement plan benefits are expensed as employees earn such benefits. The recognition of expense is significantly impacted by estimates made by management such as discount rates used to value certain liabilities, expected return on assets and future healthcare costs. We use third-party specialists to assist management in appropriately measuring the expense associated with pension and other postretirement plan benefits.

Revenue Recognition

We recognize net revenue when in the normal course of our business the following conditions are met: (i) a purchase order has been received from the customer with a corresponding order acknowledgement sent to the customer confirming delivery, price and payment terms, (ii) product has been shipped (FOB origin) or delivered (FOB destination) and title has clearly transferred to the customer or customer carrier, (iii) the price to the buyer is fixed and determinable for sales with an estimate of allowances made based on historical experience and (iv) there is reasonable assurance of collectability.

We record net revenue on a consignment sale when a customer has taken title of product which is stored in either the customer’s warehouse or that of a third party.

From time to time, we will discontinue or obsolete products that we have formerly sold. When this is done, an accrual for estimated returns is established at the time of the announcement of product discontinuation or obsolescence.

We typically warrant that our products will conform to Molex specifications and that our products will be free from material defects in materials and manufacturing, and generally limit our liability to the replacement of defective parts or the cash value of replacement parts. We will not accept returned goods unless the customer makes a claim in writing and management authorizes the return. Returns result primarily from defective products or shipping discrepancies. A reserve for estimated returns is established at the time of sale based on historical return experience and is recorded as a reduction of net revenue.

We provide certain distributors with an inventory allowance for returns or scrap equal to a percentage of qualified purchases. At the time of sale, we record as a reduction of net revenue a reserve for estimated inventory allowances based on a fixed percentage of sales that we authorized to distributors.

From time to time we in our sole discretion will grant price allowances to customers. At the time of sale, we record as a reduction of net revenue a reserve for estimated price allowances based on historical allowances authorized and approved solely at our discretion.

Other allowances include customer quantity and price discrepancies. At the time of sale, we record as a reduction of net revenue a reserve for other allowances based on historical experience. We believe we can reasonably and reliably estimate the amounts of future allowances.

Shipping and Handling Costs

Shipping and handling costs are expensed as incurred and included in cost of sales.

Research and Development

Costs incurred in connection with the development of new products and applications are charged to operations as incurred. Research and development costs are included in selling, general and administrative expenses and totaled $170.1 million, $154.0 million and $159.2 million in fiscal 2011, 2010 and 2009, respectively.

Advertising

Advertising costs are charged to operations as incurred and are included in selling, general and administrative expenses.

Income Taxes

Deferred tax assets and liabilities are recognized based on differences between the financial statement and tax bases of assets and liabilities using presently enacted tax rates. We have operations that are subject to income and other similar taxes in foreign countries. The estimation of the income tax amounts that we record involves the interpretation of complex tax laws and regulations, evaluation of tax audit findings and assessment of the impact foreign taxes may have on domestic taxes. A valuation allowance is provided to offset deferred tax assets if, based on available evidence, it is more likely than not that some or all of the deferred tax assets will not be realized.

Provision is made for taxes on undistributed earnings of foreign subsidiaries and related companies to the extent that such earnings are not deemed to be permanently invested.

Derivative Instruments and Hedging Activities

We use derivative instruments to manage our foreign exchange and commodity cost exposures. All derivative instruments are recognized at fair value in other current assets or liabilities.

We use derivative instruments to offset the impact of exchange rate volatility on certain assets and liabilities, including intercompany receivables and payables denominated in non-functional currencies. These instruments have not been designated as hedges, and the gains or losses on these derivatives, along with the offsetting losses or gains due to the fluctuation of exchange rates on the underlying foreign currency denominated assets and liabilities, are recognized in other income (expense).

We also use derivative instruments to hedge the variability of gold and copper costs. These instruments are designated as cash flow hedges. Gains and losses of the effective hedges are recorded as a component of accumulated other comprehensive income and reclassified to cost of sales during the period the commodity is sold.

Derivative instruments may give rise to counterparty credit risk. To mitigate this risk, our counterparties are required to have investment grade credit ratings.

Stock-Based Compensation

We have granted nonqualified and incentive stock options and restricted stock to our directors, officers and employees under our stock plans pursuant to the terms of such plans. We measure stock-based compensation expense based on the fair value of the award on the date of grant. We recognize compensation expense for the fair value of restricted stock grants issued based on the closing stock price on the date of grant. Compensation expense recognized on shares issued under our Employee Stock Purchase Plan is based on the value of an option to purchase shares of our stock at a 15 percent discount to the stock price.

Contingencies

In accordance with ASC 450, Contingencies, we analyze whether it is probable that an asset has been impaired or a liability has been incurred, and whether the amount of loss can be reasonably estimated. If the loss contingency is both probable and reasonably estimable, we accrue for costs associated with the loss contingency, including direct costs incurred. If no accrual is made but the loss contingency is reasonably possible, we disclose the nature of the contingency and the related estimate of possible loss or range of loss if such an estimate can be made. Loss contingencies include, but are not limited to, possible losses related to legal proceedings and regulatory compliance matters. Liabilities established to provide for contingencies are adjusted as further information develops, circumstances change, or contingencies are resolved.

Accounting Changes

Uncertainty in Income Taxes

We adopted the provisions of ASC 740-10, Accounting for Income Taxes, effective July 1, 2009. ASC 740-10 requires application of a “more likely than not” threshold to the recognition and derecognition of tax positions. The adoption of ASC 740-10 did not have a material impact on our statement of financial position or results of operations.

New Accounting Pronouncements

In June 2011, the FASB issued ASU No. 2011-05, Comprehensive Income (Topic 220). This new guidance requires the components of net income and other comprehensive income to be either presented in one continuous statement, referred to as the statement of comprehensive income, or in two separate, but consecutive statements. This new guidance eliminates the current option to report other comprehensive income and its components in the statement of stockholders’ equity. While the new guidance changes the presentation of comprehensive income, there are no changes to the components that are recognized in net income or other comprehensive income under current accounting guidance. This new guidance is effective for us for the quarter ended March 31, 2012 and will amend our presentation of the components of comprehensive income.

In April 2011, the FASB issued ASU No. 2011-04, Fair Value Measurement (Topic 820), to achieve common fair value measurement and disclosure requirements between U.S. GAAP and International Financial Reporting Standards. This new guidance, which is effective for us for the quarter ended March 31, 2012, amends current U.S. GAAP fair value measurement and disclosure guidance to include increased transparency around valuation inputs and investment categorization. We do not expect the adoption will have a material impact on our consolidated financial statements.
