| Accounting Policies [Abstract] | |
| Description of Business | (a) Description of Business TPI Composites, Inc. is the holding company that conducts substantially all of its business operations through its direct and indirect subsidiaries (collectively, the Company or we). The Company was founded in 1968 and has been producing composite wind blades since 2001. The Company is incorporated in Delaware, headquartered in Scottsdale, Arizona and has a global footprint that includes domestic facilities in Newton, Iowa; Des Moines, Iowa; Warren, Rhode Island and Santa Teresa, New Mexico and international facilities in Juárez, Mexico; Matamoros, Mexico; Izmir, Türkiye; Chennai, India; Kolding, Denmark; Berlin, Germany and Madrid, Spain. In December 2022, we committed to a restructuring plan to rebalance our organization and optimize our global manufacturing footprint. Changing economic and geopolitical factors, including increased logistics costs and tariffs imposed on components of wind turbines from China, including wind blades, had an adverse impact on demand for our wind blades manufactured in our Chinese facilities. In connection with our restructuring plan, we ceased production at our Yangzhou, China manufacturing facility as of December 31, 2022 and are in the final stages of shutting down our business operations in China. Our business operations in China comprised the entirety of our Asia reporting segment. This shut down has had a meaningful effect on our global manufacturing footprint and consolidated financial results. Accordingly, the historical results of our Asia reporting segment have been presented as discontinued operations in our Consolidated Statements of Operations and Consolidated Balance Sheets. Our China operations represented a geographic operating segment that included (1) the manufacturing of wind blades at our facilities in Dafeng, China and Yangzhou, China, (2) the manufacturing of precision molding and assembly systems at our Taicang Port, China facility and (3) wind blade inspection and repair services. The following discussion reflects continuing operations only, unless otherwise indicated. For further information regarding our discontinued operations, refer to Note 2 – Discontinued Operations. |
| Basis of Presentation | (b) Basis of Presentation The accompanying consolidated financial statements include the accounts of TPI Composites, Inc. and all majority owned subsidiaries. All significant intercompany transactions and balances have been eliminated. Certain prior period amounts in the consolidated financial statements and accompanying notes have been reclassified to conform to the current period’s presentation. |
| Revenue Recognition | (c) Revenue Recognition The majority of our revenue is generated from supply agreements associated with manufacturing of wind blades and related services. We account for a supply agreement when it has the approval from both parties, the rights of the parties are identified, payment terms are established, the contract has commercial substance and the collectability of consideration is probable. To determine the proper revenue recognition method for each supply agreement, we evaluate whether the original contract should be accounted for as one or more performance obligations. This evaluation requires judgment and the decisions reached could change the amount of revenue and gross profit recorded in a given period. As most of our contracts contain multiple performance obligations, we allocate the total transaction price to each performance obligation based on the estimated relative standalone selling prices of the promised goods or services underlying each performance obligation. Our manufacturing services are customer specific and involve production of items that cannot be sold to other customers due to the customers’ protected IP; therefore, we allocate the total transaction price under our contracts with multiple performance obligations using the contractually stated prices, as these prices represent the relative standalone selling price based on an expected cost-plus margin model. Revenue is primarily recognized over time as we have an enforceable right to payment upon termination and we may not use or sell the product to fulfill other customers’ contracts. In addition, the customer does not have return or refund rights for items produced that conform to the specifications included in the contract. Because control transfers over time, revenue is recognized based on the extent of progress towards the completion of the performance obligation. We use the cost-to-cost input measure of progress for our contracts as this method provides the best representation of the production progress towards satisfaction of the performance obligation as the materials are distinct to the product being manufactured because of customer specifications provided for in the contract, the costs incurred are proportional to the progress towards completion of the product, and the products do not involve significant pre-fabricated component parts. Under the cost-to-cost method, progress and the related revenue recognition is determined by a ratio of direct costs incurred to date in fulfillment of the performance obligation to the total estimated direct costs required to complete the performance obligation. Determining the revenue to be recognized for services performed under our supply agreements involves judgments and estimates relating to the total consideration to be received and the expected direct costs to complete the performance obligation. As such, revenue recognized reflects our estimates of future contract volumes and the direct costs to complete the performance obligation. The judgments and estimates relating to the total consideration to be received include the amount of variable consideration as our contracts typically provide the customer with a range of production output options from guaranteed minimum volume obligations to the production capacity of the facility, and customers will provide periodic non-cancellable commitments for the number of wind blades to be produced over the term of the agreement. The total consideration also includes payments expected to be received associated with wind blade model transitions, and payments expected to be received or paid in the form of liquidated damages, for missed production deadlines which are paid over a negotiated timeline. We use historical experience, customer commitments and forecasted future production based on the capacity of the plant to estimate the total revenue to be received to complete the performance obligation. In addition, the amount of consideration per unit produced may vary based on the costs of production of the wind blades as we may be able to change the price per unit based on changes in the cost of production. Further, some of our contracts provide opportunities for us to share in labor and material cost savings as well as absorb some additional costs as an incentive for more efficient production, both of which impact the margin realized on the contract and ultimately the total amount of revenue to be recognized. We estimate variable consideration at the most likely amount to which we expect to be entitled. We include estimated amounts in the transaction price to the extent it is probable that a significant reversal of cumulative revenue recognized will not occur when the uncertainty associated with the variable consideration is resolved. Our estimates of variable consideration and determination of whether to include estimated amounts in the transaction price are based largely on an assessment of our anticipated performance and all information available to us at the time of the estimate and may materially change as additional information becomes known. Our contracts may be modified to account for changes in specifications of products and changing requirements. If the contract modifications are for goods or services that are not distinct from the existing contract, they are accounted for as if they were part of the original contract. The effect of a contract modification on the transaction price and the measure of progress for the performance obligation to which it relates is recognized as an adjustment to revenue on a cumulative catch-up basis. If contract modifications are for goods and services that are distinct from the existing contract and increases the amount of consideration reflecting the standalone sale price of the additional goods or services, then the contract modification is accounted for as a separate contract and is evaluated for one or more performance obligations. Each reporting period, we evaluate the progress towards satisfaction of each performance obligation based on any contract modifications that have occurred, costs incurred to date, and an estimate of the expected future consideration and costs to be incurred to complete the performance obligation. Based on this analysis, any changes in estimates of total consideration to be received and direct costs to complete the performance obligation are recognized on a cumulative catch-up basis, which recognizes in the current period the cumulative effect of the changes on current and prior periods based on the percentage of completion of the performance obligation. Wind blade pricing is based on annual commitments of volume as established in our supply agreements and orders less than committed volume may result in a higher price per wind blade to our customers. Orders in excess of annual commitments may result in discounts to our customers from the contracted price for the committed volume. Our customers typically provide periodic purchase orders with the price per wind blade given the current cost of the bill of materials, labor requirements and volume desired. We record an allowance for expected utilization of early payment discounts which are reported as a reduction of the total consideration to be received. Precision molding and assembly systems included in a customer’s contract are based upon the specific engineering requirements and design determined by the customer and are specific to the wind blade design and function desired. From the customer’s engineering specifications, a job cost estimate is developed along with a production plan, and the desired margin is applied based on the location the work is to be performed and complexity of the customer’s design. Precision molding and assembly systems are generally built to produce wind blades which may be manufactured by us in production runs specified in the customer contract. Contract assets primarily relate to our rights to consideration for work completed but not billed at the reporting date on supply agreements. The contract assets are transferred to accounts receivable when the rights become unconditional, which generally occurs when customers are invoiced upon the determination that a product conforms to the contract specifications and invoices are due based on each customer’s negotiated payment terms, which, range from 5 to 95 days. We apply the practical expedient that allows us to exclude payment terms under one year from the transfer of a promised good or service from consideration of a significant financing component in its contracts. With regards to the production of precision molding and assembly systems, our contracts generally call for progress payments to be made in advance of production. Generally, payment is made at certain percentage of completion milestones with the final payment due upon delivery to the manufacturing facility. These progress payments are recorded within contract liabilities as current liabilities in the consolidated balance sheets and are reduced as we record revenue over time. We evaluate indications that a customer may not be able to meet the obligations under our supply agreements to determine if an account receivable or contract asset may be impaired. Our customers may request, in situations where they do not have space available to receive products or do not want to take possession of products immediately for other reasons, that their finished products be stored by us in one of our facilities. Most of our contracts provide for a limited number of wind blades to be stored during the period of the contract with any additional wind blades stored subject to additional storage fees, which are included in wind blade sales. Revenue related to field service inspection and repair services, non-recurring engineering and freight services provided under our supply agreements is recognized at a point in time following the transfer of control of the promised services to the customer. Customers usually pay the carrier directly for the cost of shipping associated with items produced. When we pay the shipping cost, we apply the practical expedient that allows us to account for shipping and handling as fulfillment costs and include the revenue in the associated performance obligation and the costs are included in cost of goods sold. Taxes assessed by a governmental authority that are both imposed on and concurrent with specific revenue-producing transactions, that are collected by us from a customer, are excluded from revenue. |
| Cost of Goods Sold | (d) Cost of Goods Sold Cost of goods sold includes the costs we incur at our production facilities to make products saleable on both products invoiced during the period as well as products in progress towards the satisfaction of the related performance obligations for which we have an enforceable right to payment upon termination and we may not use or sell the product to fulfill other customers’ contracts. All costs incurred at our production facilities, as well as the allocated portion to our production facilities of costs incurred at our corporate headquarters and our research facilities, are directly or indirectly related to the manufacturing of products or services and are presented in cost of goods sold. Cost of goods sold includes such items as raw materials, direct and indirect labor and facilities costs, including purchasing and receiving costs, plant management, inspection costs, production process improvement activities, product engineering and internal transfer costs. In addition, all depreciation associated with assets used in the production of our products is also included in cost of goods sold. Direct labor costs consist of salaries, benefits and other personnel related costs for associates engaged in the manufacturing of our products and services. Startup and transition costs are primarily unallocated fixed overhead costs and underutilized direct labor costs incurred during the period production facilities are transitioning wind blade models and ramping up manufacturing. All direct labor costs, excluding non-productive labor costs, are included in the measure of progress towards completion of the relevant performance obligation when determining revenue to be recognized during the period. The cost of sales for the initial products from a new model manufacturing line is generally higher than when the line is operating at optimal production volume levels due to inefficiencies during ramp-up related to labor hours per blade, cycle times per blade and raw material usage. Additionally, these costs as a percentage of net sales are generally higher during the period in which a facility is ramping up to full production capacity due to underutilization of the facility. Manufacturing overhead at each of our facilities includes virtually all indirect costs (including share-based compensation costs) incurred at the plants, including engineering, finance, information technology, human resources and plant management. |
| General and Administrative Expenses | (e) General and Administrative Expenses General and administrative expenses primarily relate to the unallocated portion of costs incurred at our corporate headquarters and our research facilities and include salaries, benefits and other personnel related costs for associates engaged in research and development, engineering, finance, internal audit, information technology, human resources, business development, global operational excellence, global supply chain, in-house legal and executive management. Other costs include outside legal and accounting fees, risk management (insurance), share-based compensation and certain other administrative and global resources costs. The unallocated research and development expenses incurred at our Warren, Rhode Island location as well as at our Kolding, Denmark advanced engineering center and our Berlin, Germany engineering center are also included in general and administrative expenses. For the years ended December 31, 2023, 2022 and 2021 , total research and development expenses totaled $ 1.4 million, $ 1.1 million and $ 1.0 million, respectively. |
| Loss on Sale of Assets and Asset Impairments | (f) Loss on Sale of Assets and Asset Impairments For the years ended December 31, 2023, 2022 and 2021, the losses on the sale of certain receivables, on a non-recourse basis under supply chain financing arrangements with our customers, to financial institutions, as well as the losses on the sale of other assets at our corporate and manufacturing facilities and asset impairment charges totaled $ 21.9 million, $ 9.8 million and $ 12.4 million, respectively. |
| Restructuring charges, net | (g) Restructuring Charges, Net Restructuring charges primarily consist of associate severance, one-time termination benefits and ongoing benefits related to the reduction of our workforce and other costs associated with exit activities, which may include costs related to leased facilities to be abandoned and facility and associate relocation costs. The determination of when we accrue for involuntary termination benefits under restructuring plans depends on whether the termination benefits are provided under an ongoing benefit arrangement or under a one-time benefit arrangement. Ongoing benefit arrangements are recognized over the service period or when termination becomes reasonably probable, and one-time benefit arrangements are recognized in the period the arrangement is approved and formally communicated to associates. If applicable, we record such costs into operating expense over the terminated associate’s future service period beyond any minimum retention period. Restructuring charges that have been incurred but not yet paid are recorded in accrued expenses in the accompanying consolidated balance sheets. For the years ended December 31, 2023, 2022 and 2021, restructuring charges, net totaled $ 5.1 million, $ 0.3 million and $ 12.5 million, respectively. These charges primarily related to severance benefits to terminated associates as a result of the reorganization of our operations in Türkiye, temporary shutdown of our Newton, Iowa manufacturing facility and the stop of production in one of our Juarez, Mexico facilities. |
| Cash and Cash Equivalents and Restricted Cash | (h) Cash and Cash Equivalents and Restricted Cash Cash and cash equivalents include highly liquid investments that are readily convertible to known amounts of cash with original maturities of three months or less. The carrying value of cash and cash equivalents approximates fair value. As of December 31, 2023 and 2022, our discontinued operations collectively had unrestricted cash totaling $ 0.9 million and $ 9.7 million, respectively. The Chinese government imposes certain restrictions on transferring cash out of China. The local governments in other countries in which we operate impose no such restrictions on transferring cash out of the respective country. As of December 31, 2023 and 2022 , we had $ 10.8 million and $ 9.9 million, respectively of cash held as collateral for various instruments, primarily for letters of guarantee related to our India, corporate, and Mexico locations. These amounts are reported as restricted cash in our consolidated balance sheets. |
| Accounts Receivable | (i) Accounts Receivable Trade accounts receivable are recorded at the invoiced amount and generally do not bear interest. We follow the allowance method of recognizing uncollectible accounts receivable, which recognizes bad debt expense based on a review of the individual accounts outstanding and prior history of uncollectible accounts receivable. Credit is extended based on evaluation of each of our customer’s financial condition and is generally unsecured. Accounts receivable are generally due within 30 days and are stated net of an allowance for doubtful accounts in the consolidated balance sheets. Accounts are considered past due if outstanding longer than contractual payment terms. We record an allowance based on consideration of a number of factors, including the length of time trade accounts are past due, previous loss history, the creditworthiness of individual customers, economic conditions affecting specific customer industries, and economic conditions in general. We charge-off accounts receivable after all reasonable collection efforts have been exhausted. We credit payments subsequently received on such receivables to bad debt expense in the period payment is received. We record delinquent finance charges on outstanding accounts receivables only if they are collected. We wrote off $ 10.5 million of receivables during 2023 primarily due to a write off of $ 8.1 million in accounts receivables due to Proterra's bankruptcy filing. We wrote off no receivables during 2022, or 2021. We do not have any off-balance-sheet credit exposure related to our customers. See Note 5, Accounts Receivable. |
| Inventories | (j) Inventories Inventories represent materials purchased that are not restricted to fulfillment of a specific contract and are measured at the lower of cost or net realizable value. Net realizable value is defined as the estimated selling prices in the ordinary course of business, less reasonably predictable costs of completion, disposal, and transportation. Cost is determined using the first-in, first-out method for such raw materials. Write-downs to reduce the carrying cost of obsolete, slow-moving, and unusable inventory to net realizable value are recognized in cost of goods sold. The effect of these write-downs establishes a new cost basis in the related inventory, which is not subsequently written up. |
| Property, Plant and Equipment | (k) Property, Plant and Equipment Property, plant and equipment are stated at cost. Depreciation and amortization of property, plant, and equipment is calculated on the straight-line method over the estimated useful lives of the assets. See Note 7, Property, Plant and Equipment, Net.
Estimated
Machinery and equipment 7 to 10 years
Buildings 20 years
Leasehold improvements 5 to 10 years, or the term
Office equipment and software 3 to 5 years
Furniture 3 to 5 years
Vehicles 5 years |
| Recoverability of Long-Lived Assets | (l) Recoverability of Long-Lived Assets We review property, plant and equipment and other long-lived assets in order to assess recoverability based on expected future undiscounted cash flows whenever events or circumstances indicate that the carrying value may not be recoverable. If the sum of the expected future net cash flows is less than the carrying value, an impairment loss is recognized. The impairment loss is measured as the amount by which the carrying value exceeds the fair value of the asset. |
| Assets Held for Sale | (m) Assets Held for Sale We classify long-lived assets or disposal groups to be sold as held for sale in the period in which all of the following criteria are met: (1) management, having the authority to approve the action, commits to a plan to sell the asset or disposal group; (2) the asset or disposal group is available for immediate sale in its present condition subject only to terms that are usual and customary for sales of such assets or disposal groups; (3) an active program to locate a buyer and other actions required to complete the plan to sell the asset or disposal group have been initiated; (4) the sale of the asset or disposal group is probable, and transfer of the asset or disposal group is expected to qualify for recognition as a completed sale within one year, except if events or circumstances beyond our control extend the period of time required to sell the asset or disposal group beyond one year; (5) the asset or disposal group is being actively marketed for sale at a price that is reasonable in relation to its current fair value; and (6) actions required to complete the plan indicate that it is unlikely that significant changes to the plan will be made or that the plan will be withdrawn. We initially measure a long-lived asset or disposal group that is classified as held for sale at the lower of its carrying value or fair value less any costs to sell. Any loss resulting from this measurement is recognized in the period in which the held-for-sale criteria are met. Conversely, gains are not recognized on the sale of a long-lived asset or disposal group until the date of sale. We assess the fair value of a long-lived asset or disposal group less any costs to sell each reporting period it remains classified as held for sale and report any subsequent changes as an adjustment to the carrying value of the asset or disposal group, as long as the new carrying value does not exceed the carrying value of the asset at the time it was initially classified as held for sale. Upon determining that a long-lived asset or disposal group meets the criteria to be classified as held for sale, we cease depreciation and report long-lived assets and/or the assets and liabilities of the disposal group, if material, in the line items assets held for sale and liabilities held for sale, respectively, in our consolidated balance sheets. As of December 31, 2023, we met the criteria to classify $ 17.8 million of assets and $ 1.9 million of liabilities as held for sale associated with our automotive business. The assets held for sale relate to $ 14.2 million of property, plant and equipment, net, $ 2.4 million of accounts receivables, and $ 1.2 million of other current assets. The liabilities held for sale relate to $ 1.9 million of other current liabilities. These amounts have been reclassified to assets held for sale and liabilities held for sale, respectively, in the accompanying consolidated balance sheets. We are in the process of exploring strategic alternatives to ensure our automotive business is sufficiently funded to execute on its growth strategies as we intend to prioritize capital for growth in the wind blade business in the near term. We expect to complete this process no later than June 30, 2024, which could result in a material impairment of the business's assets. Accordingly, the Company determined a triggering event had occurred and performed an analysis to evaluate if any impairment exists in the assets held for sale associated with our automotive business. The Company concluded that there were no indicators of impairment and that the carrying values of the long-lived assets equates to their fair values as of December 31, 2023. |
| Discontinued Operations | (n) Discontinued Operations In determining whether a group of assets disposed (or to be disposed) of should be presented as a discontinued operation, the Company makes a determination of whether the criteria for held-for-sale classification is met and whether the disposition represents a strategic shift that has (or will have) a major effect on the entity’s operations and financial results. If these determinations can be made affirmatively, the results of operations of the group of assets being disposed of (as well as any gain or loss on the disposal transaction) are aggregated for separate presentation apart from continuing operating results of the Company in the consolidated financial statements. As of December 31, 2023, and 2022 we met the criteria to classify the disposal of our business operations in China as discontinued operations. See Note 2, Discontinued Operations. |
| Goodwill, Intangible Assets and Deferred Costs, Net | (o) Goodwill, Intangible Assets and Deferred Costs, Net Goodwill, which is entirely in the U.S. segment, is evaluated for impairment annually on October 31 and whenever events or circumstances make it likely that impairment may have occurred. In determining whether impairment has occurred, we compare the fair value of the related reporting unit (calculated using the discounted cash flow method) to its carrying value. If the carrying value exceeds the fair value, impairment is recognized for the difference. We may first assess qualitative factors to determine whether it is necessary to perform the quantitative goodwill impairment test. We performed our annual goodwill impairment test during 2023 and determined that it is more-likely-than-not that its fair value exceeds its carrying amount. Our patents, licenses, trademarks and development tools were acquired in business acquisitions and provide contractual or legal rights, or other future benefits that could be separately identified. Our valuation of identified intangible assets was based upon discounted cash flow estimates that require significant management judgment with respect to revenue and expense growth rates, changes in working capital, and the selection and use of the appropriate discount rate. The intangible assets are amortized over their estimated useful life. Intangible assets with indefinite lives are evaluated at least annually for impairment or whenever events or circumstances make it likely that impairment may have occurred. In addition, we recognize an asset for deferred costs incurred to fulfill a contract when such costs meet certain criteria. These deferred costs are amortized over their estimated useful life. See Note 3, Net Sales for a further discussion of those deferred costs. See Note 8, Intangible Assets and Deferred Costs, Net. |
| Mezzanine Equity | (p) Mezzanine Equity We issued Series A Preferred Stock that we determined is a financial instrument with both equity and debt characteristics and is classified as mezzanine equity in our consolidated financial statements. The instrument was initially recognized at fair value net of issuance costs. We reassess whether the instrument is currently redeemable or probable to become redeemable in the future as of each reporting date, in which, if the instrument meets either criterion, we will accrete the carrying value to the estimated maximum redemption value based on the effective interest method over the remaining period to the expected redemption date. To assess classification, we review all features of the instrument, including all mandatory and optional redemption features that may be substantive. All financial instruments that are classified as mezzanine equity are evaluated for embedded derivative features by evaluating each feature against the nature of the host instrument (e.g. more equity-like or debt-like). Features identified as freestanding instruments or bifurcated embedded derivatives that are material are recognized separately as a derivative asset or liability in the consolidated financial statements. We evaluated our Series A Preferred Stock and determined that its nature is that of a debt host and embedded derivatives exist that require bifurcation on our balance sheet. Mezzanine equity is presented net of related issuance costs and discounts resulting from bifurcated instruments and embedded features issued in conjunction with the host. On December 14, 2023, we entered into a new Credit Agreement and Guaranty (the "Credit Agreement") with Oaktree Fund Administration, LLC, as administrative agent and an affiliate of the holders of our Series A Preferred Stock, which, among other things, included a new senior secured term loan (the "Term Loan") in exchange, together with the issuance of an aggregate of 3,899,903 shares of Common Stock, on a cashless basis, for all Series A Preferred stock and $ 86.0 million of accrued and unpaid dividends. See Note 12, Debt, and Note 15, Mezzanine Equity . |
| Warranty Expense | (q) Warranty Expense We provide a limited warranty for our mold, wind blade, and automotive products, including materials and workmanship, with terms and conditions that vary depending on the product sold, generally for periods that range from two to five years . Warranty expense is recorded based upon estimates of future repairs using a probability-based methodology that considers previous warranty claims, identified quality issues and industry practices. Once the warranty period has expired, any remaining unused warranty accrual for the specific products is generally reversed against the current year warranty expense amount, provided that the warranty accrual for other products whose warranty period has not yet expired is sufficient to cover the estimated cost of future repairs for those other products. See Note 10, Accrued Warranty . |
| Treasury Stock | (r) Treasury Stock Common stock purchased for treasury is recorded at historical cost. Transactions in treasury shares relate to shares withheld in lieu of income taxes associated with share-based compensation plans and are recorded at weighted-average cost. |
| Foreign Currency Translation and Income and Losses | (s) Foreign Currency Translation and Income and Losses Foreign currency-denominated assets and liabilities are translated into U.S. dollars at exchange rates existing at the respective balance sheet dates. Results of operations of our foreign subsidiaries are translated at the average exchange rates during the respective periods. Translation adjustments are reported in accumulated other comprehensive loss in our consolidated balance sheets. Currency translation adjustments for the years ended December 31, 2023, 2022 and 2021 amounted to other comprehensive income (losses) of $ ( 2.3 ) million, $( 37.7 ) million and $ 18.4 million, respectively. Our reporting currency is the U.S. dollar. However, we have non-U.S. operating subsidiaries in our U.S., Mexico, EMEA, and India segments, and our China discontinued operations. • The U.S. parent companies of our Mexico operations and China discontinued operations, which are wholly-owned subsidiaries of TPI Composites, Inc., maintain their books and records in their functional currency, the U.S. dollar. • Our Mexico operations maintain their books and records through multiple legal entities that are denominated in the local Mexican currency, the Peso, which are remeasured to their U.S. dollar functional currency. • Our Türkiye operations maintain their books and records in their functional currency, the Euro. • Our China discontinued operations maintain their books and records in their functional currency, the local Chinese currency, the Renminbi. • Our Chennai, India operations maintain their books and records in their functional currency, the U.S. dollar. • Our Kolding, Denmark operation, which is an indirect, wholly-owned subsidiary of TPI Composites, Inc., maintains its books and records in their functional currency, the local Danish currency, the Krone. • Our Berlin, Germany operation, which is an indirect, wholly-owned subsidiary of TPI Composites, Inc., maintains its books and records in their functional currency, the Euro. • Our Madrid, Spain operation, which is an indirect, wholly-owned subsidiary of TPI Composites, Inc., maintains its books and records in their functional currency, the Euro. Foreign currency transaction gains and losses are reported in foreign currency loss, net in our consolidated statements of operations. |
| Share-Based Compensation | (t) Share-Based Compensation Our incentive compensation plan provides for the issuance of incentive stock options, non-qualified stock options, stock appreciation rights, restricted stock units (RSUs), restricted stock awards, unrestricted stock awards, cash-based awards, performance-based restricted stock units (PSUs), and dividend equivalent rights to certain of our associates, non-employee directors and consultants. The term of stock options may not exceed ten years from the date of grant. Incentive stock options and non-qualified stock options are granted at an exercise price that is not to be less than 100 % of the fair market value of our common stock on the date of grant, as determined by the Compensation Committee of our board of directors. Stock options become vested and exercisable at such times and under such conditions as determined by the Compensation Committee on the date of grant. For performance stock units that are subject to market conditions, we utilize a Monte Carlo simulation model to determine the fair value. The Monte Carlo simulation model utilizes multiple input variables to determine the share-based compensation expense. For grants with market conditions made during the year ended December 31, 2023, we utilized an expected volatility assumption of 77.64 %, a 0 % dividend yield and a risk-free interest rate of 4.0 %. The volatility was based on the most recent comparable period for our peer group and us. The risk-free interest rate is equal to the yield, as of the measurement date, of the U.S. Treasury bill that is commensurate with the remaining performance measurement period. We currently do not pay a dividend. The determination of the grant date fair value using an option-pricing model and simulation model requires judgment as well as assumptions regarding a number of other complex and subjective variables. These variables include our closing market price at the grant date as well as the following assumptions: Expected Volatility . The expected volatility assumption reflects an average of our historical volatility and the volatilities of publicly traded peer group companies with a period equal to the expected life of the options. Expected Life (years) . We use the simplified method to estimate the expected term of stock options. The simplified method for estimating expected term is to use the mid-point between the vesting term and the contractual term of the option. We elected to use the simplified method because we did not have historical exercise data to estimate the expected term due to the limited time period our common stock has been publicly traded. Risk-Free Interest Rate . The risk-free interest rate assumption is based upon the U.S. constant maturity treasury rates as the risk-free rate interpolated between the years commensurate with the expected life of the options. Dividend Yield . The dividend yield assumption is zero since we do not expect to declare or pay dividends in the foreseeable future. Forfeitures. Share-based compensation expense is reversed when the service-based award is forfeited. Expected Vesting Period . We amortize the share-based compensation expense over the requisite service period. Share-based compensation expense related to RSUs and PSUs are expensed over the vesting period using the straight-line method for our associates and our board of directors. The RSUs and PSUs do not have voting rights. We calculate the fair value of our share-based awards on the date of grant for our associates and directors. |
| Leases | (u) Leases We determine if an arrangement is a lease at inception. Operating leases are included in operating lease right of use (ROU) assets, current operating lease liabilities, and noncurrent operating lease liabilities in the consolidated balance sheets. Finance leases are included in property, plant and equipment, current maturities of long-term debt, and long-term debt, net of debt issuance costs and current maturities in the consolidated balance sheets. Operating lease ROU assets and operating lease liabilities are recognized based on the present value of future minimum lease payments over the lease term at commencement date. Variable payments are not included in ROU assets or lease liabilities and can vary from period to period based on asset usage or our proportionate share of common costs. The implicit rate within our leases is generally not determinable and, therefore, the incremental borrowing rate at lease commencement is utilized to determine the present value of lease payments. We estimate our incremental borrowing rate based on third-party lender quotes to obtain secured debt in a like currency for a similar asset over a timeframe similar to the term of the lease. The ROU asset also includes any lease prepayments made and any initial direct costs incurred and excludes lease incentives. Our lease terms may include options to extend or terminate the lease when it is reasonably certain that we will exercise that option. Lease expense for minimum lease payments is recognized on a straight-line basis over the lease term. We have elected not to recognize ROU assets or lease liabilities for leases with a term of 12 months or less. We have lease agreements with lease and non-lease components. We have elected to apply the practical expedient to account for these components as a single lease component for all classes of underlying assets. See Note 13, Leases. |
| Income Taxes | (v) Income Taxes Income taxes are accounted for under the asset and liability method in accordance with FASB Accounting Standards Codification ("ASC") Topic 740, Income Taxes . Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those differences are projected to be recovered or settled. Realization of deferred tax assets is dependent on our ability to generate sufficient taxable income of an appropriate character in future periods. A valuation allowance is established if it is determined to be more-likely-than-not that a deferred tax asset will not be realized. See Note 18, Income Taxes. |
| Use of Estimates | (w) Use of Estimates The preparation of consolidated financial statements in conformity with U.S. generally accepted accounting principles (GAAP) 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. Actual results could differ from those estimates. Significant items subject to such estimates and assumptions include the useful lives of property, plant and equipment, realizability of intangible assets, deferred costs and deferred tax assets, standalone selling prices and future contract volumes and the direct costs to complete the performance obligation for revenue recognition, fair value of stock options, performance-based restricted stock units and warrants, features related to our Series A Preferred Stock, our new Term Loan, warranty reserves and other contingencies. |
| Fair Value of Financial Instruments | (x) Fair Value of Financial Instruments ASC Topic 820, Fair Value Measurements , defines fair value 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 the measurement date. Topic 820 also specifies a fair value hierarchy that requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. The standard describes three levels of inputs that may be used to measure fair value is follows: Level 1: Quoted prices in active markets for identical assets or liabilities; 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; and Level 3: Valuation is generated from model-based techniques that use significant assumptions not observable in the market. These unobservable assumptions reflect our own estimate of assumptions that market participants would use in pricing the asset or liability. The carrying amounts of our cash and cash equivalents, trade accounts receivable, income taxes receivable, accounts payable and accrued expenses and income taxes payable approximate fair value because of the short-term nature of these financial instruments. The carrying amount of our short-term unsecured loans approximates fair value due to their short-term nature and the loans carry a current market rate of interest, a Level 2 input. The Term Loan issued on December 14, 2023 was recorded at fair value resulting in an original issuance discount on the Term Loan (see Note 12, Debt ). The fair value of the Term Loan was estimated using the discounted cash flow method under the income approach, where the contractual cash flows were discounted to present value using a synthetic credit risk adjusted discount rate based on market rates for similar publicly traded debt, all of which represent Level 2 inputs. The carrying value of the Term Loan approximates fair value as of December 31, 2023, due to the short period between issuance date and year end. The carrying value of our other long-term debt approximates fair value based upon market interest rates available to us for debt of similar risk and maturities, which is a Level 2 input. Since our derivative assets and liabilities are not traded on an exchange, we value them using standard industry valuation models. As applicable, these models project future cash flows and discount the amounts to a present value using market-based observable inputs, including interest rate curves, credit risk, foreign exchange rates, and forward and spot prices for currencies. These inputs are observable in active markets over the contract term of the derivative instruments we hold, including the Event of Default Derivative associated with our Term Loan, and accordingly, we classify the valuation techniques as Level 2. See Note 12, Debt. |
| Earnings Per Share | (y) Earnings Per Share We calculate basic earnings per share for both continuing and discontinued operations, by dividing net income from continuing operations, and net income from discontinued operations, respectively, after deducting dividends on and accretion of preferred stock, by the average number of common shares outstanding during the period, which includes unissued common shares associated with vested equity awards for which little or no consideration is required prior to issuance, net of any treasury shares. We calculate diluted earnings per share for both continuing and discontinued operations in a similar manner after consideration of the potential dilutive effect of common stock equivalents on the average number of common shares outstanding during the period. Common stock equivalents include warrants, stock options, restricted stock awards and units, and performance share awards and units. Common stock equivalents are calculated based upon the treasury stock method using an average market price of common shares during the period. Dilution is not considered when a net loss from continuing operations is reported. Common stock equivalents that have an antidilutive effect are excluded from the computation of diluted earnings per share. See Note 19, Net Income (Loss) Per Share . ASC Topic 260, Effect on the Calculation of Earnings per Share for the Redemption or Induced Conversion of Preferred Stock , provides guidance on the accounting for extinguishments (redemptions) of equity-classified preferred stock. It requires the gain or loss on extinguishment of equity-classified preferred stock to be included in the net income per common stockholder used to calculate earnings per share (similar to the treatment of dividends paid on preferred stock). The difference between (1) the fair value of the consideration transferred to the holders of the preferred stock and (2) the carrying amount of the preferred stock (net of issuance costs) is subtracted from (or added to) net income to arrive at income available to common stockholders in the calculation of earnings per share. Accordingly, any excess fair value of the consideration transferred over the carrying amount of the preferred stock is charged against retained earnings, or additional paid-in capital if there are insufficient retained earnings. We applied this guidance to the accounting treatment of the Series A Preferred Stock Exchange described in Note 12, Debt . |
| Debt Discounts and Issuance Cost | (z) Debt Discounts Debt discounts on our long-term debt are recorded as a direct deduction from the carrying amount of such debt on the consolidated balance sheets. All debt discounts are amortized using the effective interest method over the term of the debt. Debt discount amortization expense is recorded as part of interest expense in the consolidated statements of operations. |
| Recently Issued Accounting Pronouncements | (aa) Recently Issued Accounting Pronouncements Supplier Finance Programs In September 2022, the FASB issued ASU 2022-04, Liabilities - Supplier Finance Programs (Subtopic 405-50), which requires the disclosure of the key terms of outstanding supplier finance programs and a roll forward of the related obligations. The new standard does not affect the recognition, measurement or financial statement presentation of supplier finance program obligations. We adopted this standard on January 1, 2023, except for the roll forward requirement, which becomes effective January 1, 2024. The new standard did not have a material impact on our consolidated financial statements. There have been no other recent accounting pronouncements or changes in accounting pronouncements during the current year that are of significance, or potential significance, to us. |
