Accounting Policies [Abstract] | |
Cash and cash equivalents | Cash and cash equivalents are comprised of highly liquid investments with original maturities of three months or less, primarily consisting of euro-denominated overnight deposits. Bank overdrafts are classified as current liabilities and presented as a financing activity on our consolidated statements of cash flows. |
Trade accounts receivable, net of reserves | Trade accounts receivable are recorded at the invoiced amount and generally do not bear interest. The carrying amount of trade accounts receivable is presented net of a reserve representing our estimate of the amounts that will not be collected and for estimated sales returns and allowances. In addition to reviewing delinquent accounts receivable, we consider many factors in estimating our reserve, including historical data, experience, customer types, creditworthiness and economic trends. From time to time, we may adjust our assumptions for anticipated changes in any of these or other factors expected to affect collectability. Account balances are written off against the allowance when we determine it is probable that the receivable will not be recovered. |
Inventories | Our inventories consist primarily of products held for sale. Inventories are valued at the lower of cost or market, cost being primarily determined by the LIFO method for certain of our U.S. subsidiaries and the first-in, first-out method for all other subsidiaries. We regularly review quantities of inventories on hand and compare these amounts to the expected use of each product or product line. We record a charge to cost of goods sold for the amount required to reduce the carrying value of inventory to net realizable value. |
Property and equipment | Property and equipment are recorded at cost. Depreciation is recognized using the straight-line method over estimated useful lives of 10 to 40 years for buildings and improvements and 3 to 10 years for equipment and computer software. Leasehold improvements are amortized on a straight-line basis over the shorter of the estimated useful lives of the assets or the estimated remaining life of the lease. Costs for repairs and maintenance that do not significantly increase the value or estimated lives of property and equipment are expensed as incurred. Property and equipment held under capital leases were not material for any periods presented. |
Impairment of long-lived assets | We evaluate the recoverability of long-lived assets when events or changes in circumstances indicate a possible inability to recover carrying amounts. We assess recoverability by comparing the carrying value of the asset to estimated undiscounted future cash flows expected to be generated by the asset. If an asset is impaired, the loss is measured as the amount by which the asset’s carrying value exceeds its fair value. |
Goodwill and other intangible assets | Goodwill represents the excess of purchase price over the fair value of net assets acquired in a business combination. Other intangible assets consist of both amortizable and indefinite-lived intangible assets. Amortizable intangible assets are amortized over their estimated useful lives on a straight-line basis. Indefinite-lived intangible assets are not amortized. We reevaluate the estimated useful lives of our amortizable intangible assets annually. For indefinite-lived intangible assets, we reevaluate annually whether they continue to have indefinite lives, considering whether they have any legal, regulatory, contractual, competitive or economic limitations and whether they are expected to contribute to the generation of cash flows indefinitely. Goodwill and other indefinite-lived intangible assets are tested annually for impairment on October 1 of each year. Goodwill impairment testing is performed at the reporting unit level. Our reporting units are the same as our operating segments and reportable segments. All of our intangible assets, including goodwill, are tested for impairment whenever an indication of potential impairment arises. Events or circumstances that might require an interim evaluation include unexpected adverse business conditions, economic factors, unanticipated technological changes or competitive activities, loss of key personnel and acts or anticipated acts by governments and courts. Indefinite-lived intangible assets are tested for impairment prior to testing of goodwill or amortizable intangible assets. The impairment analysis for goodwill and indefinite-lived intangible assets consists of an optional qualitative assessment potentially followed by a two-step quantitative analysis. If we determine that the carrying value of goodwill or indefinite-lived intangible assets exceeds its fair value, an impairment charge is recorded for the excess. Impairment charges cannot be reversed in subsequent periods. The impairment analysis for amortizable intangible assets is performed in the same way as for our other long-lived assets, as previously discussed. |
Fair value measurements | Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at a measurement date. Classification within the fair value hierarchy is based on the lowest of the following levels that is significant to the fair value measurement: • Level 1 — Quoted prices (unadjusted) in active markets for identical assets or liabilities • Level 2 — Inputs that are observable for the asset or liability, either directly or indirectly through market corroboration, for substantially the full term of the asset or liability • Level 3 — Inputs that are unobservable for the asset or liability based on our evaluation of the assumptions market participants would use in pricing the asset or liability We exercise considerable judgment when estimating fair value, particularly when evaluating what assumptions market participants would likely make. The use of different assumptions or estimation methodologies could have a material effect on the estimated fair values. |
Commitments and contingencies | Loss contingencies are reflected in the consolidated financial statements based on our assessments of the expected outcome of legal proceedings or the expected resolution of other contingencies. Liabilities for estimated losses are accrued if the potential loss from any claim or legal proceeding is considered probable and the amount can be reasonably estimated. Significant judgment is required to determine probability and whether the amount of an exposure is reasonably estimable. Due to uncertainties related to these matters, accruals are based only on the information available at the time. As additional information becomes available, we reassess potential liabilities related to pending claims and litigation and may revise our previous estimates. |
Revenue recognition | We record product revenue on a gross basis when persuasive evidence of an arrangement exists, the price is fixed or determinable, title and risk of loss have been transferred to the customer and collectability of the resulting receivable is reasonably assured. Title and risk of loss is transferred at the time of shipment or upon delivery to customers, depending upon the terms of the arrangement with the customer. Products are delivered without post-sale obligations to the customer. Provisions for discounts, rebates to customers, sales returns and other adjustments are provided for as a reduction of sales in the period the related sales are recorded. We record shipping and handling charges billed to customers in net sales and record shipping and handling costs in cost of goods sold for all periods presented. Sales taxes, value-added taxes and certain excise taxes collected from customers and remitted to governmental authorities are accounted for on a net basis and therefore are excluded from net sales. Services represent a growing but currently small portion of our net sales and were not material to our consolidated financial statements. |
Classification of expenses - cost of goods sold | Cost of goods sold includes the cost of the product, vendor rebates, inbound and outbound freight charges, as well as inventory adjustments. |
Classification of expenses - SG&A expenses | SG&A expenses include personnel and facility charges, advertising and promotional charges and other charges related to our global infrastructure operations. |
Stock-based compensation | Stock-based compensation consists primarily of stock options awarded to employees and directors. We measure expense using the grant-date fair value of awards ultimately expected to vest. Awards with service conditions are expensed on a straight-line basis from the date of grant through the end of the requisite service period. We issue new shares of common stock upon the exercise of stock options. The grant-date fair value of stock options is measured using a closed-form option pricing model, using assumptions based on the terms of each stock option agreement, the expected behavior of grant recipients and peer company data. We have limited historical data about our own awards upon which to base our assumptions. Expected volatility is calculated based on the observed equity volatility for a peer group over a period of time equal to the expected life of the stock options. The risk-free interest rate is based on U.S. Treasury observed market rates continuously compounded over the duration of the expected life. The expected life of stock options is determined using the simplified method, which is calculated as the midpoint of the weighted average vesting period and the contractual term. We elect to recognize expense based on the number of awards ultimately expected to vest by use of an estimated forfeiture rate. The estimated forfeiture rate is based on historical data for the employee group awarded options and expected employee turnover rates, which management reevaluates each period. |
Defined benefit plans | Some of our employees participate in defined benefit plans. The benefits include pension, salary continuance, life insurance and healthcare. Benefits are accrued over the employees’ service periods. We use actuarial methods and assumptions in the valuation of defined benefit obligations and the determination of net periodic pension income or expense. Differences between actual and expected results or changes in the value of defined benefit obligations and plan assets, if any, are not recognized in earnings as they occur but rather systematically over subsequent periods. |
Foreign currency translation | Assets and liabilities of our foreign subsidiaries, where the functional currency is the local currency, are translated into U.S. dollars using period-end exchange rates. Revenues, expenses, income and losses are translated using average exchange rates. Resulting translation adjustments are reported in accumulated other comprehensive income or loss. Foreign currency remeasurement gains and losses related to financing activities are reported in other income (expense), net within our consolidated statements of operations, while gains and losses associated with operating activities are reported within the applicable component of operating income. |
Income taxes | Income taxes are accounted for under the asset and liability method. Deferred tax assets and liabilities are recognized for the expected net tax effects of temporary differences between the carrying amounts of assets and liabilities for financial reporting and income tax purposes and for net operating loss and credit carryforwards. Deferred tax assets and liabilities are measured using the enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. We record a valuation allowance to reduce deferred tax assets to the amount that is more likely than not to be realized. We recognize the effect of income tax positions only if those positions are more likely than not to be sustained. Recognized income tax positions are measured at the largest amount that is more likely than not of being realized. Changes in recognition or measurement are reflected in the period in which a change in judgment occurs, as a result of information that arises or when a tax position is effectively settled. We recognize accrued interest and penalties related to unrecognized tax benefits as a component of income tax expense in our consolidated financial statements. |
Due to Varietal — ITRA | We record the estimated amount payable to Varietal under an ITRA, entered into in connection with our IPO, as a noncurrent liability, except for the portion estimated to be payable within one year. The ITRA liability was initially recognized through an adjustment to additional paid-in capital and measured at its expected future value, similar to the underlying deferred tax assets to which it relates. Subsequent changes to the value of the ITRA liability, if any, will be classified as other income (expense), net in the consolidated statements of operations. Cash payments under the ITRA are classified as a financing activity on the consolidated statements of cash flows. |
