| Nature of Business and Summary of Significant Accounting Policies | NATURE OF BUSINESS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Nature of Business — IPG Photonics Corporation (the "Company" or "IPG") develops, manufactures and sells high-performance fiber lasers, fiber amplifiers, and diode lasers that are used for diverse applications, primarily in materials processing. The Company was incorporated as a Delaware corporation in December 1998. Its world headquarters is located in Marlborough, Massachusetts. It also has facilities and sales offices elsewhere in North and South America, Europe and Asia. Russian Operations — In October 2022, the European Union (“EU”) issued sanctions that restricted the Company’s Russian subsidiary from supplying laser components to its other manufacturing facilities beginning in January 2023. These EU sanctions, coupled with increased tariffs in the United States on items imported from Russia, negatively affected what had been the Russian subsidiary’s most significant source of revenue, which was selling components and finished goods to other IPG subsidiaries. As a result of these changes in business conditions in Russia at the end of 2022, the Company completed an impairment analysis of assets in Russia during the fourth quarter of 2022 and recorded charges in the accompanying Consolidated Statement of Income. In 2022, the Company recorded $74,055 of inventory provision and related charges included in Cost of sales, $79,030 of impairment of long-lived asset charges included in Impairment of long-lived assets and a $35,518 valuation allowance for deferred tax assets included in provision for income taxes. The long-lived asset impairment charge was based on a probability-weighted average of valuations using the discounted cash flow method under the income approach, the guideline public company method and the guideline transaction method under the market approach, to estimate the fair value of the long-lived assets in Russia. Further, in 2022 the Company implemented a restructuring program at its Russian subsidiary and recorded restructuring charges of $8,542 for personnel-related restructuring charges and other post employment benefits included in Restructuring charges (recoveries), net. In 2023, the Company substantially completed the restructuring program. As a result, the remaining restructuring accrual was substantially recovered. This resulted in net restructuring recoveries of $288 for the year ended December 31, 2023. Principles of Consolidation — The accompanying financial statements include the accounts of the Company and its majority-owned subsidiaries. All intercompany accounts and transactions have been eliminated. Use of Estimates — The preparation of 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, disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenue and expenses during the reporting period. The Company bases its estimates on historical experience and on various other assumptions that are believed to be reasonable under the circumstances. Actual results could differ from those estimates. Foreign Currency — The financial information for entities outside the United States is measured using local currencies as the functional currency. Assets and liabilities are translated into U.S. dollars at the exchange rate in effect on the respective balance sheet dates. Income and expenses are translated into U.S. dollars based on the average rate of exchange for the corresponding period. Exchange rate differences resulting from translation adjustments are accounted for directly as a component of accumulated other comprehensive (loss) income. Cash and Cash Equivalents and Short-Term Investments — Cash and cash equivalents consist primarily of highly liquid investments, such as money market fund deposits, term deposits, corporate bonds, and commercial paper with maturities of three months or less at the date of purchase with insignificant interest rate risk. Short-term investments consist of liquid investments including commercial paper, corporate bonds, U.S. government and government agency notes and term deposits with original maturities of greater than three months but less than one year with insignificant interest rate risk. Fixed-term securities included in cash equivalents and short-term investments are held-to-maturity and accounted for at amortized cost. Accounts Receivable and Allowance for Doubtful Accounts — Accounts receivable include $17,313 and $12,977 of bank acceptance drafts at December 31, 2023 and 2022, respectively. Bank acceptance drafts are bank guarantees of payment on specified dates. The weighted average maturity of these bank acceptance drafts is approximately 102 days. The Company maintains an allowance for doubtful accounts to provide for the estimated amount of accounts receivable that will not be collected. The allowance is based upon an estimate of expected credit losses over the life of outstanding receivables. The estimate involves an assessment of customer creditworthiness, historical payment experience, an assumption of future expected credit losses, and the age of outstanding receivables. Activity related to the allowance for doubtful accounts was as follows: 2023 2022 2021 Balance at January 1 $ 2,639 $ 2,108 $ 2,156 Provision for bad debts, net of recoveries 36 712 434 Uncollectible accounts written off (840) (125) (437) Foreign currency translation (72) (56) (45) Balance at December 31 $ 1,763 $ 2,639 $ 2,108 Inventories — Inventories are stated at the lower of cost and net realizable value on a first-in, first-out basis. Inventories include parts and components that may be specialized in nature and subject to obsolescence. The Company periodically reviews the quantities and carrying values of inventories to assess whether the inventories are recoverable. The costs associated with provisions for excess quantities, technological obsolescence, or scrap related to out of specification components are charged to cost of sales as incurred. Goodwill — Goodwill is the amount by which the cost of the acquired net assets in a business acquisition exceeded the fair values of the net identifiable assets on the date of purchase. Goodwill is assessed for impairment at least annually, on a reporting unit basis, or more frequently when events and circumstances occur indicating that the recorded goodwill may be impaired. The process of evaluating the potential impairment of goodwill is subjective and requires significant judgment at many points during the analysis. If the carrying value of a reporting unit exceeds its fair value, the implied fair value of goodwill is compared with the carrying value of goodwill. If the carrying value of goodwill exceeds the implied fair value, an impairment loss is recorded in an amount equal to that excess. The results of the goodwill assessments for the years ended December 31, 2023 and 2022 are discussed in Note 7, "Goodwill and Intangible Assets". Intangible Assets — Intangible assets result from the Company's various business acquisitions. Intangible assets are reported at cost, less accumulated amortization, and are amortized on a straight-line basis either over their estimated useful lives of one year to thirteen years or over the period the economic benefits of the intangible asset are consumed. Property, Plant and Equipment — Property, plant and equipment are stated at cost, less accumulated depreciation. Depreciation is determined using the straight-line method based on the estimated useful lives of the related assets. In the case of leasehold improvements, the estimated useful lives of the related assets do not exceed the remaining terms of the corresponding leases. The following table presents the assigned economic useful lives of property, plant and equipment: Category Economic Useful Life Buildings 20-30 years Machinery and equipment 5-7 years Office furniture and fixtures 5-7 years Expenditures for maintenance and repairs are charged to operating expenses when they are incurred. Long-Lived Assets — Long-lived assets, which consist primarily of property, plant and equipment and identifiable intangible assets, are reviewed by management for impairment whenever events or changes in circumstances indicate that the carrying amount may not be recoverable. When undiscounted expected future cash flows are less than the carrying value, an impairment loss is recorded equal to the amount by which the carrying value exceeds the fair value of assets. The impact of the long-lived assets impairment for the years ended December 31, 2023, and 2022 are discussed in Note 8, "Property, Plant and Equipment" and Note 13, "Leases". Included in other long-term assets is certain demonstration equipment. The demonstration equipment is amortized over the respective estimated economic lives, generally 3 years. The carrying value of the demonstration equipment totaled $3,726 and $3,686 at December 31, 2023 and 2022, respectively. Amortization expense of demonstration equipment for the years ended December 31, 2023, 2022 and 2021, was $3,480, $2,387 and $3,596, respectively. Authorized Capital — The Company has authorized capital stock consisting of 175,000,000 shares of common stock, par value $0.0001 per share, and 5,000,000 shares of preferred stock, par value $0.0001 per share. There are no shares of preferred stock outstanding as of December 31, 2023. Revenue Recognition — Revenue is recognized when transfer of control to the customer occurs in an amount reflecting the consideration that the Company expects to be entitled. In order to achieve this 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. The Company considers customer purchase orders, which in some cases are governed by master sales agreements, to be contracts with a customer. As part of its consideration of the contract, the Company evaluates certain factors including the customer's ability to pay (or credit risk). For each contract, the Company considers the promise to transfer products, each of which is identified as a distinct performance obligation. In determining the transaction price, the Company evaluates whether the price is subject to refund or adjustment to determine the net consideration to which the Company expects to be entitled. As the Company's standard payment terms are less than one year, the Company has elected the practical expedient under ASC 606-10-32-18 to not assess whether a contract has a significant financing component. The Company allocates the transaction price to each distinct product based on its relative standalone selling price. Revenue is recognized when control of the product is transferred to the customer (i.e., when the Company's performance obligation is satisfied), which typically occurs at shipment but which can occur over time for certain of the Company's systems contracts. The Company often receives orders with the customer's schedule of delivery dates for products that may extend across several reporting periods. The Company allocates the transaction price of the contract to each delivery based on the product standalone selling price. The Company invoices for each scheduled delivery upon shipment and recognizes revenues for such delivery at that point, when transfer of control has occurred. As scheduled delivery dates are generally within one year, under the optional exemption provided by ASC 606-10-50-14 revenues allocated to future shipments of partially completed contracts are not disclosed. Rights of return are not generally included in customer contracts. Accordingly, upon application of steps one through five above, product revenue is recognized upon shipment and transfer of control. Returns are infrequent and are recorded as a reduction of revenue. In certain subsidiaries the Company provides sales commissions to sales representatives based on sales volume. The Company has determined that the incentive portion of its sales commissions qualify as contract costs. The Company has elected the practical expedient in ASC 340-40-25-4 to expense sales commissions when incurred as the amortization period of the asset that would otherwise have been recognized is one year or less. Revenue Recognition at a Point in Time — Revenues recognized at a point in time consist primarily of product, installation and service sales. The Company sells products to original equipment manufacturers ("OEMs") that supply materials processing laser systems, communications systems, medical laser systems and other laser systems for advanced applications to end users. The Company also sells products to end users that use IPG products directly to build their own systems, which incorporate or use IPG products as an energy or light source. The Company recognizes revenue for laser and spare part sales following the transfer of control of such products to the customer, which typically occurs upon shipment or delivery depending on the terms of the underlying contracts. Installation revenue is recognized upon completion of the installation service, which typically occurs within 90 days of delivery. When sales contracts contain multiple performance obligations, such as the shipment or delivery of products and installation, the Company allocates the transaction price to each performance obligation identified in the contract based on relative standalone selling prices and recognizes the related revenue as control of each individual product or service is transferred to the customer, in satisfaction of the corresponding performance obligations. Revenue Recognition over Time — Warranties are limited and provide that the product meets specifications and is free from defects in materials and workmanship. The Company also offers extended warranty agreements, which extend the standard warranty periods. Extended warranties are sold separately from products and represent a distinct performance obligation. Revenue related to the performance obligation for extended warranties is recognized over time as the customer simultaneously receives and consumes the benefits provided by the Company. The customer receives the assurance that the product will operate in accordance with agreed-upon specifications evenly during the extended warranty period regardless of whether they make a claim during that period, and therefore, revenue at time of sale is deferred and recognized over the time period of the extended warranty period. The Company enters into contracts to sell customized large scale materials processing systems through its subsidiary Genesis Systems Group, LLC, for which revenue is generally recognized over time, depending on the terms of the contract. Recognizing revenue over time for these contracts is based on the Company’s judgment that the customized large scale materials processing systems do not have an alternative use and the Company has an enforceable right to payment for performance completed to date. The determination of the revenue to be recognized in a given period for performance obligations over time is based on the input method. The Company generally uses the total cost-to-cost input method of progress because it best depicts the transfer of control to the customer that occurs as costs are incurred. Under the cost-to-cost method, the extent of progress towards completion is measured based on the proportion of costs incurred to date to the total estimated costs at completion of the performance obligation. Customer Deposits and Deferred Revenue — When the Company receives consideration from a customer or such consideration is unconditionally due prior to transferring goods or services under the terms of a sales contract, the Company records customer deposits or deferred revenue, which represent contract liabilities. The Company recognizes deferred revenue as net sales after control of the goods or services has been transferred to the customer and all revenue recognition criteria are met. Warranties — The Company typically provides one Stock-based Compensation — The Company accounts for stock-based compensation expense using the fair value of the awards granted. The Company issues equity incentive awards in the form of time-based restricted stock units ("RSUs") and performance-based restricted stock units ("PSUs"). The fair value for RSUs is based on the closing share price of the Company's common stock on the date of grant. PSUs are aligned to specified performance targets such as financial metrics or the relative return of the Company's common stock compared to an index ("TSR PSUs"). The fair value of PSUs aligned to specified financial performance metrics is determined based on the number of units expected to vest upon achievement of the performance conditions. The fair value for PSUs aligned to the TSR is based on a Monte Carlo simulation model. The Company recognizes stock-based compensation as an expense on a straight-line basis, over the requisite service period. The Company accounts for forfeitures as they occur. The Company has an employee stock purchase plan ("ESPP") offered to its U.S. and German employees. The Company uses the Black-Scholes model to calculate the purchase date fair value of the shares issued under the employee stock purchase plan and recognize expense related to shares purchased ratably over the offering period. The description of the Company's stock-based compensation plans and the assumptions it uses to calculate the fair value of stock-based compensation is described in Note 15, "Stock-based Compensation." Advertising Expense — The cost of advertising is expensed as incurred. The Company conducts substantially all of its sales and marketing efforts through trade shows, professional and technical conferences, direct sales and the Company's website. The Company's advertising costs were not material for the periods presented. Research and Development — Research and development costs are expensed as incurred. Restructuring — The Company records charges associated with approved restructuring plans to reorganize operations, to remove redundant headcount and infrastructure associated with business acquisitions or to improve the efficiency of business processes. Restructuring charges can include severance costs to eliminate a specific number of positions, infrastructure charges to vacate facilities and consolidate operations and contract cancellation costs. The Company records restructuring charges when they are probable and estimable. The Company accrues for severance and other employee separation costs under these plans when the plan is communicated to employees and an amount per employee can be reasonably estimated either by the communicated terms, or by legal requirements, if applicable. The results of restructuring program implemented during the years ended December 31, 2023, and 2022 are discussed in Note 6, "Restructuring". Income Taxes — Deferred tax assets and liabilities are recognized for the future tax consequences of temporary differences between the financial statement carrying amounts and the tax basis of assets and liabilities and net operating loss and credit carryforwards. These differences are valued using enacted rates in effect when those differences are expected to reverse. Valuation allowances are provided against deferred tax assets that are not deemed to be recoverable. The Company recognizes tax positions that are more likely than not to be sustained upon examination by relevant tax authorities. The tax positions are measured at the greatest amount of tax benefit that is more than 50 percent likely to be realized upon ultimate settlement. The Company provides reserves for potential payments of tax to various tax authorities related to uncertain tax positions and other issues. The reserves are based on a determination of whether a tax benefit claimed in our tax filings is more likely than not to be realized following the resolution of any potential tax audits related to the tax benefit, assuming that the matter in question will be reviewed by the tax authorities. Concentration of Credit Risk — Financial instruments that potentially subject the Company to credit risk consist primarily of cash and cash equivalents, short-term investments and accounts receivable. The Company maintains substantially all of its cash and cash equivalents and short-term investments in various financial institutions, which it believes to be high-credit quality financial institutions. The Company grants credit to customers in the ordinary course of business and provides a reserve for potential credit losses. Such losses historically have been within management's expectations. One of our customers accounted for 14% of our net accounts receivable as of both December 31, 2023 and 2022. The Company has historically depended on a few customers for a significant percentage of its annual net sales. The composition of this group can change from year to year. Net sales derived from the Company's five largest customers as a percentage of its annual net sales were 13%, 15% and 19% in 2023, 2022 and 2021, respectively. Comprehensive Income — Comprehensive income includes charges and credits to equity that are not the result of transactions with stockholders. Included within comprehensive income is the cumulative foreign currency translation adjustment, and unrealized gains or losses on derivatives. These adjustments are accumulated within the consolidated statements of comprehensive income. Total components of accumulated other comprehensive loss were as follows: Foreign currency translation adjustments and other Unrealized (loss) gain on derivatives, net of tax Total Balance, January 1, 2021 $ (145,603) $ (462) $ (146,065) Other comprehensive (loss) income, net of tax: Foreign currency translation adjustments and other, net of tax benefit of $246 (44,164) — (44,164) Unrealized gain on derivatives, net of tax of $83 — 278 278 Total other comprehensive (loss) income (44,164) 278 (43,886) Balance, December 31, 2021 (189,767) (184) (189,951) Other comprehensive (loss) income, net of tax: Foreign currency translation adjustments and other before reclassification, net of tax of $156 (15,117) — (15,117) Reclassification for foreign currency translation adjustments and other included in net income 208 — 208 Unrealized gain on derivatives, net of tax of $104 — 336 336 Total other comprehensive (loss) income (14,909) 336 (14,573) Balance, December 31, 2022 (204,676) 152 (204,524) Other comprehensive loss, net of tax: Foreign currency translation adjustments and other before reclassification, net of tax of $151 (7,854) — (7,854) Unrealized (loss) on derivatives, net of tax benefit of $46 — (152) (152) Total other comprehensive loss (7,854) (152) (8,006) Balance, December 31, 2023 $ (212,530) $ — $ (212,530) Derivative Instruments — The Company's primary market exposures are to interest rates and foreign exchange rates. The Company from time to time may use certain derivative financial instruments to help manage these exposures. The Company executes these instruments with financial institutions it judges to be credit-worthy. The Company does not hold or issue derivative financial instruments for trading or speculative purposes. The Company recognizes all derivative financial instruments as either assets or liabilities at fair value in the consolidated balance sheets. Business Segment Information — The Company operates in one segment which involves the design, development, production and distribution of fiber lasers, laser and non-laser systems, fiber amplifiers, and related optical components. The Company has a single, company-wide management team that administers all properties as a whole rather than as discrete operating segments. The chief operating decision maker, who is the Company's chief executive officer, measures financial performance as a single enterprise, and not on geography, legal entity, or end market basis. Throughout the year, the chief operating decision maker allocates capital resources on a project-by-project basis across the Company's entire asset base to maximize profitability without regard to geography, legal entity, or end market basis. The Company operates in a number of countries throughout the world in a variety of product lines. Information regarding product lines and geographic financial information is provided in Note 2, "Revenue from Contracts with Customers" and Note 8, "Property, Plant and Equipment." Earnings Per Share — Basic net income per common share is computed by dividing net income attributable to common shareholders of the Company by the weighted-average number of common shares outstanding during the reporting period. Diluted net income per common share is computed similarly to basic net income per common share, except that it includes the potential dilution that could occur if dilutive securities were exercised. Information about potentially dilutive and antidilutive shares for the reporting period is provided in Note 18, "Net Income Attributable to IPG Photonics Corporation Per Share." Leases — The Company determines if an arrangement is a lease at inception. Operating leases are included in other assets, accrued expenses and other liabilities, and other long-term liabilities and deferred income taxes on the Company's consolidated balance sheets. Right of use ("ROU") assets and lease liabilities are recognized based on the present value of the future minimum lease payments over the lease term at commencement date. As most of the Company's leases do not provide an implicit rate, IPG uses its incremental borrowing rate based on the information available at commencement date in determining the present value of future payments. The ROU assets include any lease payments made and initial direct costs incurred and exclude lease incentives. Lease terms may include options to extend or terminate the lease when it is reasonably certain that the Company will exercise that option. Lease expense for minimum lease payments is recognized on a straight-line basis over the lease term. Leases with an initial term of 12 months or less are not recorded on the balance sheet; the Company recognizes lease expense for these leases on a straight-line basis over the lease term. The Company has lease agreements with lease and non-lease components, which are accounted for as a single lease component. Recent Accounting Pronouncements Adopted Pronouncements — None. Pronouncements Currently Under Evaluation - In November 2023, the FASB issued ASU No. 2023-07, "Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures" ("ASU 2023-07"), which improves reportable segment disclosure requirements, primarily through enhanced disclosures about significant segment expenses on an annual and interim basis. Under the new guidance an entity is required to disclose the title and position of the chief operating decision maker ("CODM") and an explanation of how the CODM uses the reported measure(s) of segment profit or loss in assessing segment performance and deciding how to allocate resources. The ASU also requires that an entity that has a single reportable segment provide all the disclosures required by this ASU and all existing segment disclosures in Topic 280. ASU 2023-07 is effective for fiscal years beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024. The Company is evaluating the impact of this ASU and does not expect this standard will have a material impact. In December 2023, the FASB issued ASU No. 2023-09, "Income Taxes (Topic 740): Improvements to Income Tax Disclosures" ("ASU 2023-07"), which requires an entity on an annual basis to disclose specific categories in the rate reconciliation and provide additional information for reconciling items that meet a quantitative threshold. The guidance also requires an entity to disclose on an annual basis information about income taxes paid. ASU 2023-07 is effective for fiscal years beginning after December 15, 2024. The Company is evaluating the impact of this ASU and does not expect this standard will have a material impact. |
