Accounting Policies |
Principles of Consolidation | Principles of Consolidation ​ The consolidated financial statements include the accounts of the Company and its majority and wholly-owned subsidiaries. Upon consolidation, all intercompany accounts and transactions are eliminated.
Cash Equivalents | Cash Equivalents ​ Cash equivalents consist of instruments with original maturities of three months or less and consist primarily of money market funds, for which the carrying amount is a reasonable estimate of fair value.
Allowance for Credit Losses | Allowance for Credit Losses ​ The allowance for credit losses is established to represent the Company’s best estimate of the net realizable value of the outstanding amount of receivables that it will be unable to collect. The Company developed financial asset pools that consist of business or legal entities with similar risk and economic characteristics, including types of products and customers, trade receivable characteristics, and history of credit losses on trade receivables. The development of the Company’s allowance for credit losses varies by asset pool, but in general is based on a review of past due amounts, historical write-off experience, aging trends affecting specific accounts, changes in customer payment terms, general operational factors affecting all accounts and as applicable current economic conditions and reasonable and supportable forecasted economic conditions that affect collectability. In addition, factors are developed in certain regions utilizing historical trends of sales and returns and allowances and cash discount activities to derive a reserve for returns and allowances and cash discounts. The Company also monitors the creditworthiness of the Company’s largest customers and periodically reviews customer credit limits to reduce risk. If circumstances relating to specific customers change or unanticipated changes occur in the general business environment, the Company’s estimates of the recoverability of receivables could be further adjusted.
Concentration of Credit | Concentration of Credit ​ The Company sells products to a diversified customer base and, therefore, has no significant concentrations of credit risk. In 2024, 2023 and 2022, no customer accounted for 10% or more of the Company’s total sales or accounts receivable.
Inventories | Inventories ​ Inventories are stated at the lower of cost or net realizable value using standard costs determined primarily on the first-in, first-out method which approximates actual costs. The Company utilizes both specific product identification and historical product demand as the basis for estimating its excess or obsolete inventory reserve, which is evaluated at least quarterly. The Company identifies all inventories that exceed a range of one to three years in sales to calculate inventory on hand that exceeds estimated demand. This is determined by comparing the current inventory balance against unit sales for the trailing twelve months. New products added to inventory within the past twelve months are excluded from this analysis. A portion of the Company’s products contain recoverable materials, therefore the excess and obsolete reserve is established net of any estimated recoverable amounts based on historical experience. Changes in market conditions, lower-than-expected customer demand or changes in technology or features could result in additional excess or obsolete inventory that is not saleable and could require additional inventory reserve provisions.
Goodwill and Other Intangible Assets | Goodwill and Other Intangible Assets ​ Goodwill is recorded when the consideration paid for acquisitions exceeds the fair value of net tangible and intangible assets acquired. Goodwill and other intangible assets with indefinite useful lives are not amortized, but rather are tested for impairment at least annually or more frequently if events or circumstances indicate that it is “more likely than not” that they might be impaired, such as from a change in business conditions. The Company performs its annual goodwill and indefinite-lived intangible assets impairment assessment in the fourth quarter of each year.
Long-Lived Assets | Long-Lived Assets ​ Intangible assets with estimable lives and other long-lived assets are reviewed for indicators of impairment at least quarterly or more frequently if events or changes in circumstances indicate that the carrying amount of an asset or asset group may not be recoverable.
Property, Plant and Equipment | Property, Plant and Equipment ​ Property, plant and equipment are recorded at cost. Depreciation is provided on a straight-line basis over the estimated useful lives of the assets, which range from 10 to 40 years for buildings and improvements and 2 to 15 years for machinery and equipment. Leasehold improvements are depreciated over the lesser of the economic useful life of the asset or the remaining lease term.
Acquisitions | Acquisitions ​ The Company utilizes the acquisition method of accounting under ASC 805, Business Combinations, (“ASC 805”), for all transactions and events in which it obtains control over one or more other businesses, to recognize the fair value of all assets and liabilities acquired, and in establishing the acquisition date fair value as of the measurement date for all assets and liabilities assumed. The Company also utilizes ASC 805 for the initial recognition and measurement, subsequent measurement and accounting, and disclosure of assets and liabilities arising from contingencies in business combinations. Other estimates include: ​
| ● | Estimated step-ups for fixed assets and inventory;
| ● | Estimated fair values of intangible assets; and
| ● | Estimated income tax assets and liabilities assumed from the acquiree.
​ While the Company uses its best estimates and assumptions as part of the purchase price allocation process to accurately value assets acquired and liabilities assumed at the business acquisition date, the estimates and assumptions are inherently uncertain and subject to refinement. As a result, during the purchase price allocation period, which is generally one year from the business acquisition date, the Company records adjustments to the assets acquired and liabilities assumed, with the corresponding offset to goodwill. For changes in the valuation of intangible assets between the preliminary and final purchase price allocation, the related amortization is adjusted in the period it occurs. Subsequent to the purchase price allocation period, any adjustment to assets acquired or liabilities assumed is included in operating results in the period in which the adjustment is determined.
Leases | Leases ​ The Company has leases for the following classes of underlying assets: real estate, automobiles, manufacturing equipment, facility equipment, office equipment and certain service arrangements that are dependent on an identified asset. The Company, as the lessee, recognizes in the consolidated balance sheets a liability to make lease payments and a right-of-use (“ROU”) asset representing the right to use the underlying asset for both finance and operating leases with a lease term longer than twelve months. The Company elected the short-term lease recognition exemption for all leases that qualify and does not recognize ROU assets or lease liabilities for short-term leases. The Company recognizes short-term lease payments on a straight-line basis over the lease term in the consolidated statements of operations. Measuring the lease liability requires certain estimates and judgments. These estimates and judgments include how the Company determines 1) the discount rate it uses to discount the unpaid lease payments to present value; 2) the lease term; and 3) lease payments.
| ● | The present value of lease payments is determined using the interest rate implicit in the lease, if that rate is readily determinable; otherwise, the Company uses its incremental borrowing rate. Generally, the Company cannot determine the interest rate implicit in the lease because it does not have access to the lessor’s estimated residual value or the amount of the lessor’s deferred initial direct costs. Therefore, the Company uses the incremental borrowing rate as the discount rate for the lease. The Company’s incremental borrowing rate for a lease is the rate of interest it would have to pay on a collateralized basis to borrow an amount equal to the lease payments under a similar term. The Company’s incremental borrowing rate is determined by using a portfolio approach by geographic region, considering many factors, such as the Company’s specific credit risk, the amount of the lease payments, collateralized nature of the lease, both borrowing term and the lease term, and geographical economic considerations.
​
| ● | The lease term for all of the Company’s leases includes the fixed, noncancelable term of the lease plus (a) all periods, if any, covered by options to extend the lease if the Company is reasonably certain to exercise that option, (b) all periods, if any, covered by an option to terminate the lease if the Company is reasonably certain not to exercise that option, and (c) all periods, if any, covered by an option to extend (or not to terminate) the lease in which exercise of the option is controlled by the lessor. When determining if a renewal option is reasonably certain of being exercised, the Company considers several economic factors, including but not limited to, the significance of leasehold improvements incurred on the property, whether the asset is difficult to replace, underlying contractual obligations, or specific characteristics unique to that particular lease that would make it reasonably certain to exercise such option.
​
| ● | Lease payments included in the measurement of the lease liability include the following:
| o | Fixed payments, including in-substance fixed payments, owed over the lease term (which includes termination penalties the Company would owe if the lease term assumes Company exercise of a termination option), less any lease incentives paid or payable to the Company;
| o | Variable lease payments that depend on an index or rate initially measured using the index or rate at the commencement date;
| o | Amounts expected to be payable under a Company-provided residual value guarantee; and
| o | The exercise price of a Company option to purchase the underlying asset if the Company is reasonably certain to exercise that option.
Variable lease payments associated with the Company’s leases are recognized in the period when the event, activity, or circumstance in the lease agreement on which those payments are assessed occurs and are included in cost of goods sold or within selling, general and administrative expenses in the consolidated statements of operations, based on the primary use of the ROU asset.
Income Taxes | Income Taxes ​ Income taxes are accounted for under the asset and liability method. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases and operating loss and tax credit carry forwards. Deferred tax assets and liabilities are measured using 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. ​ The Company recognizes tax benefits when the item in question meets the more–likely–than-not (greater than 50% likelihood of being sustained upon examination by the taxing authorities) threshold. ​
Foreign Currency Translation | Foreign Currency Translation ​ The functional currency for most of the Company’s foreign subsidiaries is their local currency. For non-U.S. subsidiaries that transact in a functional currency other than the U.S. dollar, assets and liabilities are translated at current rates of exchange at the balance sheet date. Income and expense items are translated at the average foreign currency exchange rates for the period. Adjustments resulting from the translation of the financial statements of foreign operations into U.S. dollars are excluded from the determination of net income and are recorded in accumulated other comprehensive loss, a separate component of equity. Transaction gains and losses are included in other (income) expense, net in the consolidated statements of operations. For subsidiaries where the functional currency of the assets and liabilities differs from the local currency, non-monetary assets and liabilities are translated at the rate of exchange in effect on the date assets were acquired while monetary assets and liabilities are translated at current rates of exchange as of the balance sheet date. Income and expense items are translated at the average foreign currency rates for the period. Translation adjustments for these subsidiaries are included in other (income) expense, net in the consolidated statements of operations.
Stock-Based Compensation | Stock-Based Compensation ​ The Company records compensation expense in the financial statements for share-based awards based on the grant date fair value of those awards for restricted stock awards and deferred stock awards. Stock-based compensation expense for restricted stock awards and deferred stock awards is recognized over the requisite service periods of the awards on a straight-line basis, which is generally commensurate with the vesting term. The performance stock units offered by the Company to employees are amortized to expense over the vesting period, if deemed probable of achievement, and based on the Company’s performance relative to the performance goals, which may be adjusted over the attainment period. Changes to the estimated shares expected to vest will result in adjustments to the related share-based compensation expense that will be recorded in the period of change. The Company accounts for forfeitures as they occur, rather than estimate expected forfeitures over the vesting period of the respective grant.
Cloud Computing Arrangements | Cloud Computing Arrangements ​ The Company capitalizes certain costs related to the acquisition and development of internal use software, including implementation costs incurred in a cloud computing arrangement, during the application development stages of projects. Capitalized implementation costs are amortized on a straight-line basis over the expected term of the hosting arrangement, which includes consideration of the non-cancellable contractual term and reasonably certain renewals. Costs incurred during the preliminary project or the post-implementation/operation stages of the project are expensed as incurred. Implementation costs are included in “Other assets” in our Consolidated Balance Sheets. Once the implementation of a cloud computing arrangement is complete and ready for its intended use, the Company commences amortization of the capitalized implementation costs. Amortization is included in the same line item in the Consolidated Statements of Operations as the expense for fees for the associated hosting arrangement.
Financial Instruments | Financial Instruments ​ In the normal course of business, the Company manages risks associated with commodity prices, foreign exchange rates and interest rates through a variety of strategies, including the use of hedging transactions, executed in accordance with the Company’s policies. The Company’s hedging transactions include, but are not limited to, the use of various derivative financial and commodity instruments. As a matter of policy, the Company does not use derivative instruments unless there is an underlying exposure. Any change in value of the derivative instruments would be substantially offset by an opposite change in the value of the underlying hedged items. The Company does not use derivative instruments for trading or speculative purposes. ​ Derivative instruments may be designated and accounted for as either a hedge of a recognized asset or liability (fair value hedge) or a hedge of a forecasted transaction (cash flow hedge). For a fair value hedge, both the effective and ineffective portions of the change in fair value of the derivative instrument, along with an adjustment to the carrying amount of the hedged item for fair value changes attributable to the hedged risk, are recognized in earnings. For a cash flow hedge, changes in the fair value of the derivative instrument that are highly effective are deferred in accumulated other comprehensive income or loss until the underlying hedged item is recognized in earnings. The Company had interest rate swaps and foreign exchange hedges designated as cash flow hedges as of December 31, 2024. Refer to Note 17 for further details. ​ If a fair value or cash flow hedge were to cease to qualify for hedge accounting or be terminated, it would continue to be carried on the balance sheet at fair value until settled, but hedge accounting would be discontinued prospectively. If a forecasted transaction were no longer probable of occurring, amounts previously deferred in accumulated other comprehensive income or loss would be recognized immediately in earnings. On occasion, the Company may enter into a derivative instrument that does not qualify for hedge accounting because it is entered into to offset changes in the fair value of an underlying transaction which is required to be recognized in earnings (natural hedge). These instruments are reflected in the consolidated balance sheets at fair value with changes in fair value recognized in earnings. Portions of the Company’s outstanding debt are exposed to interest rate risks. The Company monitors its interest rate exposures on an ongoing basis to maximize the overall effectiveness of its interest rates.
Fair value Measurements | Fair Value Measurements ​ Fair value is defined as 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 on the measurement date. An entity is required to maximize the use of observable inputs, where available, and minimize the use of unobservable inputs when measuring fair value. ​ The Company has certain financial assets and liabilities that are measured at fair value on a recurring basis and certain nonfinancial assets and liabilities that may be measured at fair value on a nonrecurring basis. The fair value disclosures of these assets and liabilities are based on a three-level hierarchy, which is defined as follows: ​
Level 1 | Quoted prices in active markets for identical assets or liabilities that the entity has the ability to access at the measurement date.
​ | ​
Level 2 | Observable inputs other than Level 1 prices, such as quoted prices for similar assets or liabilities, quoted prices in markets that are not active or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities.
​ | ​
Level 3 | Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities.
​ Assets and liabilities subject to this hierarchy are classified in their entirety based on the lowest level of input that is significant to the fair value measurement. The Company’s assessment of the significance of a particular input to the fair value measurement in its entirety requires judgment and considers factors specific to the asset or liability. Refer to Note 17 for further details.
Shipping and Handling | Shipping and Handling ​ Shipping and handling costs included in selling, general and administrative expense amounted to $85.5 million, $71.5 million and $73.4 million for the years ended December 31, 2024, 2023 and 2022, respectively.
Research and Development | Research and Development ​ Research and development costs included in selling, general, and administrative expense amounted to $70.4 million, $67.1 million and $59.4 million for the years ended December 31, 2024, 2023 and 2022, respectively.
Revenue Recognition | Revenue Recognition ​ The Company recognizes revenue under the core principle to depict the transfer of control to the Company’s customers in an amount reflecting the consideration to which the Company expects to be entitled. In order to achieve that core principle, the Company applies the following five-step approach: (1) identify the contract with a customer, (2) identify the performance obligations in the contract, (3) determine the transaction price, (4) allocate the transaction price to the performance obligations in the contract, and (5) recognize revenue when a performance obligation is satisfied. When determining the transaction price of each contract, we consider contractual consideration payable by the customer and assess variable consideration that may affect the total transaction price. Variable consideration, consisting of early payment discounts, rebates and other sources of price variability, are included in the estimated transaction price based on both customer-specific information as well as historical experience. The Company regularly reviews its estimates of variable consideration on the transaction price and recognizes changes in estimates on a cumulative catch-up basis as if the most current estimate of the transaction price adjusted for variable consideration had been known as of the inception of the contract. ​ The Company’s revenue for product sales is recognized on a point in time model, at the point control transfers to the customer, which is generally when products are shipped from the Company’s manufacturing or distribution facilities or when delivered to the customer’s named location. Sales tax, value-added tax, or other taxes collected concurrent with revenue producing activities are excluded from revenue. Freight costs billed to customers for shipping and handling activities are included in revenue with the related cost included in selling, general and administrative expenses. See Note 4 for further disclosures and detail regarding revenue recognition.
Estimates | Estimates ​ The preparation of financial statements in conformity with accounting principles generally accepted in the United States 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 financial statements and the reported amounts of revenues and expenses during the reporting period. The use of estimates in specific accounting policies is described further below as appropriate. Actual results could differ from those estimates.
Recently Adopted Accounting Standards | Recently Adopted Accounting Standards ​ In November 2023, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2023-07 "Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures" which expands annual and interim disclosure requirements for reportable segments, primarily through enhanced disclosures about significant segment expenses. Additionally, it requires a public entity to disclose the title and position of the Chief Operating Decision Maker (“CODM”). The ASU does not change how a public entity identifies its operating segments, aggregates them, or applies the quantitative thresholds to determine its reportable segments. The Company adopted this standard for its annual reporting beginning January 1, 2024 and has included the required additional disclosures in the Segment Information footnote of the consolidated financial statements for the year ending December 31, 2024. ​ Accounting Standard Updates ​ In March 2024, the Securities and Exchange Commission (“SEC”) adopted climate-related reporting rules, “The Enhancement and Standardization of Climate-Related Disclosures for Investors” (the “SEC Climate Reporting Rules”), which require the disclosure of material Scope 1 and Scope 2 greenhouse gas emissions and other climate-related topics in annual reports and registration statements. In April 2024, the SEC issued a stay on the rules until legal challenges to the rule are addressed, and in February 2025 the SEC requested that the court pause arguments in the case as the SEC reconsiders its position in the litigation. The Company is monitoring the legal challenges and assessing the impact of the rules on its disclosures. ​ In December 2023, the FASB issued ASU 2023-09 "Income Taxes (Topics 740): Improvements to Income Tax Disclosures" to expand the disclosure requirements for income taxes, specifically related to the rate reconciliation and income taxes paid. ASU 2023-09 is effective for our annual periods beginning January 1, 2025, with early adoption permitted. The Company is currently evaluating the potential effect that the updated standard will have on the Company’s financial statement disclosures. ​ In November 2024, the FASB issued ASU 2024-03 "Income Statement - Reporting Comprehensive Income (Subtopic 220-40): Expense Disaggregation Disclosures" to expand the disclosure requirements of certain expense categories included in the income statement. ASU 2024-03 is effective for our annual periods beginning January 1, 2027, with early adoption permitted. The Company is currently evaluating the potential effect that the updated standard will have on the Company’s financial statement disclosures.
