Section 1 — Executive Summary
1.1 Purpose and Scope of Economic Analysis
This Appendix B to the bilateral Advance Pricing Agreement ("APA") application presents the detailed economic analyses supporting the transfer pricing methodologies proposed by Halcyon Semiconductor Inc. ("HSI") and Halcyon Semiconductor AG ("HSAG," and together with HSI, the "Applicants") for their controlled intercompany transactions. This appendix is filed as an integral component of the APA application submitted pursuant to Revenue Procedure 2015-41, 2015-35 I.R.B. 263, and Article 25 (Mutual Agreement Procedure) of the Convention between the United States of America and the Federal Republic of Germany for the Avoidance of Double Taxation and the Prevention of Fiscal Evasion with Respect to Taxes on Income and Capital and to Certain Other Taxes, signed June 29, 2006, as amended by protocol (the "Treaty").
The economic analyses presented herein encompass three categories of controlled transactions between HSAG, the German parent entity, and HSI, its wholly owned U.S. subsidiary. These three transaction categories collectively represent the full scope of intercompany dealings between HSAG and HSI that are subject to transfer pricing scrutiny under Section 482 of the Internal Revenue Code of 1986, as amended (the "Code"), and the corresponding German provisions under § 1 AStG and §§ 90(3), 162(3)–(4) AO.
The proposed APA term covers five prospective tax years, commencing January 1, 2025, and ending December 31, 2029. The Applicants additionally request rollback treatment for three prior tax years, commencing January 1, 2022, and ending December 31, 2024, in accordance with Rev. Proc. 2015-41, § 2.04. The total covered period therefore spans eight tax years (2022–2029), providing certainty and eliminating the risk of double taxation for the entirety of the relevant period.
All economic analyses contained in this appendix have been prepared in accordance with the arm's-length standard as articulated in Section 482 of the Code, Treasury Regulations §§ 1.482-1 through 1.482-9, and the OECD Transfer Pricing Guidelines for Multinational Enterprises and Tax Administrations (2022 edition) (the "OECD Guidelines"). Where relevant, reference is also made to the German transfer pricing documentation requirements under the Gewinnabgrenzungsaufzeichnungsverordnung ("GAufzV") and applicable administrative guidance issued by the German Federal Ministry of Finance.
1.2 Covered Transactions Summary
The three categories of controlled transactions covered by this APA application are summarized below.
Transaction 1 — Tangible Goods (Wafer/Die Sales). HSAG manufactures semiconductor wafers and singulated die at its fabrication facilities located in Dresden (Fab 1 and Fab 2, Industriepark Klotzsche, Zur Wetterwarte 50, 01109 Dresden) and Chemnitz (Fab 3, Technologiepark Chemnitz, Annaberger Straße 240, 09125 Chemnitz) and sells such products to HSI under the Master Intercompany Supply Agreement, originally effective January 1, 2019, and amended July 1, 2022 (the "Supply Agreement"). For fiscal year 2024, the aggregate value of intercompany goods transferred from HSAG to HSI under the Supply Agreement was €987,600,000, equivalent to approximately $1,076,000,000 at the average 2024 EUR/USD exchange rate of 1.0896. HSI subsequently resells these products—following testing, packaging, and certain local value-added activities—to unrelated third-party customers in the United States, including original equipment manufacturers ("OEMs"), electronic component distributors, and hyperscale data-center operators.
Transaction 2 — Royalties (IP License). HSI pays HSAG a running royalty under the intellectual Property License Agreement, effective January 1, 2019 (the "IP License Agreement"), for the right to use HSAG's proprietary semiconductor process technology and design libraries in connection with HSI's U.S. distribution and design-support activities. The royalty is computed at a rate of 6.0% on IP-attributable revenues, as defined in the IP License Agreement. For fiscal year 2024, total royalty payments from HSI to HSAG amounted to €68,400,000, equivalent to approximately $70,500,000 at the weighted average payment-date EUR/USD exchange rate of 1.0307.
Transaction 3 — Cost-Sharing Contributions (R&D CSA). HSAG and HSI are parties to a Qualified Cost Sharing Arrangement (the "CSA"), effective July 15, 2018, for the joint development of next-generation 2nm and sub-2nm semiconductor process technology. Under the CSA, HSI bears a cost-sharing percentage of 22.5% of qualified R&D costs. For fiscal year 2024, total qualified R&D costs subject to the CSA amounted to €998,200,000, and HSI's share was €224,600,000, equivalent to approximately $231,300,000. Simultaneously with the execution of the CSA, HSI made a Platform Contribution Transaction ("PCT") buy-in payment to HSAG of $312,500,000 in consideration for HSI's interest in pre-existing intangible property contributed to the arrangement.
The aggregate annual intercompany flows between HSAG and HSI for fiscal year 2024 across all three transaction categories totaled €987,600,000 + €68,400,000 + €224,600,000 = €1,280,600,000 (approximately €1.28 billion), underscoring the materiality and significance of these controlled transactions.
1.3 Summary of Proposed Transfer Pricing Methods and Results
The following table summarizes the transfer pricing methods proposed for each covered transaction, the tested party, the applicable profit level indicator or pricing metric, and the arm's-length results:
As the table above reflects, each of the three categories of controlled transactions between HSAG and HSI produces results that fall within the arm's-length range under the selected best method. The proposed APA terms, as described in detail in Sections 5, 6, and 7 below, are designed to maintain arm's-length pricing throughout the eight-year covered period.

Section 3 — Functional Analysis
3.1 Overview and Methodology
A detailed functional analysis was conducted as a foundational component of the economic analyses presented in this appendix. The functional analysis identifies and evaluates the functions performed, assets employed, and risks assumed by each of HSAG and HSI in connection with the three categories of covered transactions. The purpose of this analysis is to determine the relative contributions and economic profiles of the parties, to characterize each entity for purposes of selecting the most appropriate transfer pricing method and tested party, and to ensure proper application of the arm's-length standard.
The functional analysis was conducted on the basis of the following sources of information:
(a) In-person and videoconference interviews with key personnel at HSI, including Victor Almeida (President and General Manager), Priya Raghavan (Vice President of Tax), and Thomas Kuroda (Vice President of Supply Chain Operations), conducted in Austin, Texas, during the week of March 10–14, 2025;
(b) Videoconference interviews with key personnel at HSAG, including Dr. Hendrik Möller (Chief Technology Officer) and Dr. Erwin Fassbinder (Senior Vice President, Group Tax), conducted during the weeks of March 17–21 and March 24–28, 2025;
(c) Review and analysis of the intercompany agreements (Supply Agreement, IP License Agreement, and CSA), including all amendments and supplements;
(d) Review and analysis of internal management reports, organizational charts, process flow diagrams, and operational documentation provided by both HSI and HSAG;
(e) Analysis of financial data for HSAG and HSI for fiscal years 2020–2024, including audited financial statements, trial balances, and intercompany transaction schedules; and
(f) Review of publicly available industry analyses and market reports pertaining to the semiconductor fabrication and distribution industries.
The functional analysis is consistent with the requirements of Treasury Regulation § 1.482-1(d)(3), which provides that the degree of comparability between controlled and uncontrolled transactions is determined by considering the functions performed, assets used, and risks assumed by the parties, as well as the contractual terms, economic conditions, and property or services transferred. The analysis is also consistent with Chapter I of the OECD Guidelines, which establishes that a functional analysis is a necessary prerequisite for any transfer pricing analysis.
3.2 HSAG — Functions Performed, Assets Employed, Risks Assumed

• Technology Obsolescence Risk: The semiconductor industry is characterized by rapid technological change. HSAG bears the risk that its process technologies may become obsolete before the company has fully recouped its R&D and capital investments.
• Market Risk (Strategic): HSAG bears the strategic market risk associated with its investment decisions, including fab construction, capacity expansion, and technology roadmap selections.
• Product Liability Risk: HSAG bears primary product liability risk for defects in the semiconductor products it manufactures.
• Inventory Risk (Raw Materials and Work-in-Process): HSAG bears the risk of inventory obsolescence for raw materials and work-in-process held at its fabrication facilities.
• Foreign Exchange Risk: HSAG is exposed to foreign exchange risk arising from the EUR-denominated cost base and multi-currency revenue streams.
• Regulatory Risk: HSAG bears the risk of changes in environmental, trade, and export control regulations that could affect its manufacturing operations or market access.
Characterization. Based on the foregoing analysis, HSAG is characterized as the complex, IP-rich principal entity within the Halcyon semiconductor supply chain. HSAG is the entrepreneurial risk bearer and the primary value driver. HSAG performs the high-value functions (R&D, advanced manufacturing, process technology development), owns the critical intangible assets (process technology, design libraries, patents), and bears the significant risks (R&D risk, manufacturing risk, technology obsolescence risk). HSAG's functional profile is that of a fully integrated, entrepreneurial semiconductor manufacturer and technology developer.
3.3 HSI — Functions Performed, Assets Employed, Risks Assumed

Assets Employed. HSI employs the following principal assets:
• Working Capital: HSI maintains significant working capital in the form of accounts receivable (approximately $685,000,000 as of December 31, 2024) and finished goods inventory (approximately $412,000,000), financed in part by the $600,000,000 revolving credit facility with Ridgeline National Bank.
• Limited Intangibles: HSI possesses limited intangible assets, including customer lists and customer relationships developed through its sales and marketing activities, local marketing intangibles (brand awareness in the U.S. market, though Halcyon brand value is primarily attributable to HSAG), and workforce in place.
• Design Center Facility: HSI leases approximately 45,000 square feet for its Santa Clara design center.
• Office Leases: HSI leases office space for its Austin headquarters (approximately 120,000 square feet), Southfield regional sales office, and Beaverton regional sales office.
• IT Systems: HSI operates enterprise resource planning (ERP) systems, customer relationship management (CRM) platforms, and design-support tools, all of which are largely standardized commercial software products.
Risks Assumed. HSI assumes the following principal risks:
• Inventory Risk (Limited): HSI bears inventory risk with respect to finished goods held for resale, including the risk of obsolescence if customer demand shifts or products reach end-of-life. However, this risk is mitigated by the Supply Agreement's provisions for inventory return and price protection in certain circumstances.
• Credit Risk: HSI bears credit risk with respect to customer receivables. HSI manages this risk through credit assessments, credit insurance, and collection procedures.
• Limited Market Risk: HSI bears limited market risk in that changes in U.S. market conditions may affect its sales volumes and pricing. However, HSI does not bear the strategic market risk associated with technology investments and capacity decisions, which rests with HSAG.
• Foreign Exchange Risk (Partial): HSI's intercompany purchases are denominated primarily in euros, exposing HSI to EUR/USD exchange rate fluctuations. This risk is partially managed through the pricing mechanisms in the Supply Agreement and periodic hedging activities.
HSI notably does not bear the following risks, which are assumed by HSAG:
• HSI does not bear R&D risk. HSI's only R&D-related financial obligation is its 22.5% cost-sharing contribution under the CSA, which entitles HSI to a proportionate interest in the resulting CSA Intangibles.
• HSI does not bear manufacturing risk. HSI does not operate fabrication facilities and does not manufacture semiconductor products.
• HSI does not bear technology obsolescence risk with respect to process technology. Such risk resides with HSAG as the technology developer and owner.
Characterization. Based on the foregoing analysis, HSI is characterized as the least complex entity in the controlled transactions. HSI functions as a limited-risk distributor with ancillary design-support capabilities. HSI performs routine distribution, marketing, and customer-facing functions, employs primarily working capital assets and limited intangibles, and bears limited risks relative to HSAG. HSI does not own or control the critical value-driving intangible assets (process technology, design libraries, patents), does not perform core R&D, and does not operate manufacturing facilities. HSI's functional profile is most comparable to that of an independent semiconductor distributor, making it the appropriate tested party for the CPM/TNMM analysis of the tangible goods transaction.
Ridgeline National Bank Credit Facility. As noted in Section 2.2 above, HSI maintains a $600,000,000 revolving credit facility with Ridgeline National Bank, N.A. The existence of this facility is indicative of HSI's working capital requirements, which are substantial given the capital-intensive nature of the semiconductor distribution business (with large accounts receivable and inventory balances). However, the Credit Facility does not alter HSI's characterization as a limited-risk distributor, as the borrowing supports routine operational liquidity needs rather than entrepreneurial risk-taking or capital investment in productive assets.
3.4 Functional Comparison — HSAG vs. HSI
The following table provides a comparative summary of the functions performed, assets employed, and risks assumed by HSAG and HSI across all three categories of controlled transactions:
Conclusion. The functional analysis demonstrates that HSAG is the complex, IP-rich, entrepreneurial entity that performs the high-value functions, owns the critical intangible assets, and bears the significant risks in the Halcyon semiconductor supply chain. HSI, by contrast, is the least complex party—a limited-risk distributor with ancillary design-support functions. Accordingly, HSI is the appropriate tested party for the CPM/TNMM analysis of the tangible goods transaction (Transaction 1). For the royalty transaction (Transaction 2), HSAG is the tested party in its capacity as licensor, with the arm's-length royalty rate determined under the CUT method. For the CSA (Transaction 3), the anticipated benefit share analysis evaluates the relative anticipated benefits of both participants.
Section 4 — Industry Analysis
4.1 Global Semiconductor Industry Overview
The global semiconductor industry represents one of the most technologically intensive and economically significant sectors of the world economy. Understanding the industry's dynamics, structure, and cyclical patterns is essential to evaluating the comparability of the benchmarking data used in this economic analysis and to assessing the reasonableness of the transfer pricing outcomes.
Market Size and Growth. The global semiconductor market generated total revenue of approximately $575 billion in fiscal year 2024, reflecting a partial recovery from the cyclical downturn experienced in 2023. Over the five-year benchmarking period (FY 2020–2024), the industry experienced the following trajectory:
• FY 2020: Global semiconductor revenue of approximately $440 billion. The year was characterized by the initial disruption of the COVID-19 pandemic, followed by a sharp rebound in demand driven by accelerated digitization, remote work infrastructure buildout, and automotive production recovery in the second half of the year.
• FY 2021: Revenue surged to approximately $555 billion, driven by acute global supply shortages across virtually all semiconductor segments. The well-publicized "chip shortage" resulted from a combination of pandemic-related supply disruptions, surging demand from consumer electronics and automotive sectors, and structural underinvestment in manufacturing capacity.
• FY 2022: The market reached a cyclical peak of approximately $580 billion. While automotive and industrial segments remained robust, consumer-facing segments (smartphones, personal computers) began to exhibit demand softening in the second half of the year as pandemic-era demand pulled forward began to normalize.
• FY 2023: Revenue declined to approximately $530 billion as the cyclical correction fully materialized. Excess inventory accumulated during the shortage period was worked down, order cancellations increased, and pricing pressure emerged across multiple segments. The correction was most pronounced in memory semiconductors but also affected logic and analog segments.
• FY 2024: The market recovered to approximately $575 billion, driven by robust demand for artificial intelligence (AI) accelerators and data-center infrastructure, continued growth in automotive semiconductors, and the completion of inventory correction in most segments.
Key Segments. HSAG's products serve three primary end-market segments, each with distinct demand drivers and growth characteristics:
• Automotive Semiconductors: The automotive semiconductor market has experienced structural growth driven by the proliferation of advanced driver-assistance systems (ADAS), electric vehicle (EV) powertrains, and in-vehicle connectivity. Semiconductor content per vehicle has increased substantially, from approximately $490 per vehicle in 2020 to approximately $690 per vehicle in 2024. HSAG is a significant supplier of power management ICs, sensor interface chips, and networking processors for automotive applications.
• Industrial IoT: The industrial IoT segment encompasses semiconductors used in factory automation, process control, smart building systems, and edge computing applications. This segment has exhibited steady growth, driven by the ongoing "Industry 4.0" transformation and the increasing deployment of connected sensors and edge intelligence devices.
• Data Center: The data-center segment has been the fastest-growing semiconductor end market in recent years, fueled by the expansion of hyperscale cloud infrastructure and, more recently, the explosive growth in AI training and inference workloads. HSAG supplies high-performance computing accelerator chips and networking processors for data-center applications.
Capital Intensity and R&D Investment. The semiconductor manufacturing industry is among the most capital-intensive industries in the world. Construction of a single advanced-node fabrication facility requires capital investment of $10 billion to $20 billion or more. Leading semiconductor manufacturers typically invest 20–30% of revenue in capital expenditures and 15–20% of revenue in research and development. HSAG's FY 2024 R&D expenditure of €1,420,000,000 (16.2% of consolidated revenue) is consistent with industry norms for advanced-node semiconductor manufacturers.
Cyclicality. The semiconductor industry is well recognized as being highly cyclical, with periods of supply shortage and elevated margins alternating with periods of overcapacity and margin compression. The five-year benchmarking period (FY 2020–2024) captures a complete cycle, encompassing the COVID-19-driven demand shock and supply shortage (2020–2021), the cyclical peak (2022), the inventory correction and demand downturn (2023), and the partial recovery (2024). The use of a five-year benchmarking period, as discussed in Section 5.7 below, is specifically intended to smooth the effects of cyclicality and produce a reliable measure of arm's-length profitability across the full cycle.
4.2 Competitive Dynamics
Advanced-Node Fabrication. The competitive landscape for advanced-node semiconductor fabrication (sub-10nm process technology) has become increasingly concentrated over the past decade. Only a small number of companies worldwide possess the technical capabilities and financial resources to develop and manufacture semiconductors at the 7nm node and below. HSAG is one of this select group, competing primarily with a handful of East Asian and North American rivals. The barriers to entry in advanced-node fabrication are extraordinarily high, encompassing the multi-billion-dollar capital investment required for fab construction, the deep process technology expertise accumulated over decades of research, and the extreme precision demanded by sub-10nm lithography and patterning.
HSAG has established a strong competitive position in 7nm, 5nm, and 3nm process technologies for automotive and industrial applications, where the emphasis is on reliability, qualification to stringent automotive standards (AEC-Q100), and long product lifecycles rather than the cutting-edge performance metrics that characterize consumer-focused semiconductor manufacturing. This application-specific focus differentiates HSAG from competitors who primarily target high-volume consumer and mobile segments.
Distribution Channels. In the U.S. semiconductor market, distribution occurs through two primary channels: direct sales to OEMs and hyperscale customers, and sales through authorized electronic component distributors. HSI employs a hybrid model, with approximately 60% of its U.S. revenue derived from direct sales to OEMs and hyperscalers and approximately 40% derived from sales through authorized distributors. This distribution model is comparable to that employed by other major semiconductor companies operating in the North American market.
4.3 Economic Conditions Affecting Comparability
Impact of Cyclicality on Distributor Operating Margins. The cyclical nature of the semiconductor industry has a significant impact on the operating margins of semiconductor distributors. During periods of supply shortage (such as 2021–2022), distributors may benefit from favorable pricing dynamics and strong demand, resulting in above-average margins. Conversely, during cyclical downturns (such as 2023), margin compression from inventory write-downs, pricing pressure, and lower volumes typically depresses profitability. This cyclical variability is a critical consideration in the benchmarking analysis and provides the primary justification for the use of five-year weighted average operating margin data (FY 2020–2024) to smooth cyclical effects, consistent with Treasury Regulation § 1.482-1(f)(2)(iii)(D) and OECD Guidelines ¶ 3.75.
Currency Effects. The EUR/USD exchange rate exhibited meaningful fluctuation during the benchmarking period. The average annual EUR/USD rates during the period were approximately 1.1422 (2020), 1.1827 (2021), 1.0530 (2022), 1.0813 (2023), and 1.0896 (2024). These fluctuations affect the translation of HSAG's EUR-denominated intercompany prices into U.S. dollars for purposes of HSI's financial statements. While the benchmarking analysis for the tangible goods transaction focuses on HSI's operating margin computed from its USD-denominated financial statements, the currency effects are relevant context for understanding the relationship between intercompany pricing and HSI's reported profitability.
Section 5 — Economic Analysis: Transaction 1 — Tangible Goods (Wafer/Die Sales)
5.1 Transaction Description
Under the Master Intercompany Supply Agreement, HSAG manufactures semiconductor wafers and singulated die at its three fabrication facilities in Dresden and Chemnitz, Germany, and sells these products to HSI for subsequent resale to unrelated third-party customers in the United States. HSI purchases the products on CIF Houston, Texas terms and takes title and risk of loss upon delivery. HSI subsequently performs incoming inspection, warehousing, and, where required, customer-specific packaging, testing, and labeling before distributing the products to end customers.
For fiscal year 2024, the aggregate value of intercompany tangible goods transferred from HSAG to HSI was €987,600,000, equivalent to approximately $1,076,000,000 at the average 2024 EUR/USD exchange rate of 1.0896. This represents the single largest category of controlled transactions between the parties and constitutes the primary determinant of HSI's cost of goods sold and, consequently, its operating margin.
The products transferred encompass a wide range of semiconductor devices manufactured on the 7nm, 5nm, and 3nm process nodes, including power management integrated circuits, sensor interface chips, automotive microcontrollers, networking processors, and data-center accelerator chips. The products are highly specialized, differentiated by process node, die size, functionality, and application-specific qualification requirements, which, as discussed below, renders the Comparable Uncontrolled Price method unreliable for this transaction.
5.2 Method Selection — Best Method Analysis
The selection of the most appropriate transfer pricing method for the tangible goods transaction was performed in accordance with the best method rule set forth in Treasury Regulation § 1.482-1(c), which provides that the arm's-length result of a controlled transaction must be determined under the method that provides the most reliable measure of an arm's-length result given the facts and circumstances. The analysis also considers the method selection guidance provided in OECD Guidelines Chapter II.
The following methods were considered:
Comparable Uncontrolled Price (CUP) Method
The CUP method, as described in Treasury Regulation § 1.482-3(b), determines an arm's-length price by reference to the price charged in comparable uncontrolled transactions. The CUP method was considered but rejected as the best method for this transaction. HSAG's semiconductor wafers and singulated die are highly specialized products manufactured on advanced process nodes (7nm, 5nm, 3nm) for specific automotive, industrial, and data-center applications. No sufficiently comparable uncontrolled transactions involving the sale of comparable advanced-node semiconductor wafers between unrelated parties were identified. The products differ materially from those available in the open market in terms of process node, die size, functionality, application-specific qualification, and reliability requirements. Any adjustments necessary to account for these product differences would be so extensive as to render the CUP analysis unreliable.
Resale Price Method (RPM)
The Resale Price Method, as described in Treasury Regulation § 1.482-3(c), determines an arm's-length price by subtracting an appropriate gross margin from the resale price. The RPM was considered but rejected. While the RPM is conceptually appropriate for distribution transactions, its reliability in this case is undermined by the difficulty of identifying comparable gross margins for semiconductor distributors with varying levels of value-added functions. In particular, differences in cost classification among comparable companies—specifically, the treatment of design-support and applications engineering costs as either cost of goods sold or operating expenses—reduce the reliability of gross-margin comparisons. An operating-margin comparison under the CPM/TNMM avoids these classification differences and provides a more reliable measure.
Cost Plus Method
The Cost Plus Method, as described in Treasury Regulation § 1.482-3(d), determines an arm's-length price by adding an appropriate markup to the costs incurred by the supplier. The Cost Plus Method was rejected for two independent reasons. First, HSAG is the complex, IP-rich entity and is inappropriate as the tested party under a one-sided method; there are no reliable comparable contract manufacturers that can serve as comparables for a vertically integrated, advanced-node semiconductor manufacturer of HSAG's nature. Second, even if cost-plus were applied to HSI's cost base, such application would be less reliable than an operating-margin analysis given HSI's characterization as a distributor (for which net resale revenue is the more appropriate denominator).
Comparable Profits Method (CPM) / Transactional Net Margin Method (TNMM)
The CPM (under Treasury Regulation § 1.482-5) and the TNMM (under OECD Guidelines Chapter II, Part III) were selected as the best method for the tangible goods transaction. The CPM/TNMM evaluates whether the tested party earns an arm's-length level of operating profits from the controlled transaction by comparing the tested party's profit level indicator to those of comparable uncontrolled companies.
The selection of the CPM/TNMM as the best method is supported by the following considerations:
(a) HSI has been identified as the least complex entity in the controlled transaction, making it the appropriate tested party. HSI's functions, assets, and risks are those of a limited-risk distributor, which is a common business model for which reliable comparable data is available.
(b) Operating margin on net resales is a reliable and well-established profit level indicator for distribution activities, and its computation is not materially affected by differences in cost classification among comparable companies.
(c) A robust set of 17 comparable North American semiconductor distributors has been identified, providing a statistically meaningful benchmark.
(d) The CPM/TNMM is the method most frequently applied and accepted by the IRS and the BZSt for distribution transactions of this nature.
Profit Split Method
The Profit Split Method, as described in Treasury Regulation § 1.482-6, was considered but not selected as the primary method for the tangible goods transaction. The profit split method is most appropriate when both parties to the transaction make unique and valuable contributions that cannot be reliably benchmarked using a one-sided method. In this case, however, HSI's contributions are routine and can be reliably benchmarked against independent distributors, making the CPM/TNMM a more direct and reliable approach. The residual profit split method is, however, employed as a corroborative analysis in connection with the royalty transaction (see Section 6.6 below).
Conclusion. The CPM/TNMM is the best method under Treasury Regulation § 1.482-1(c) for determining whether the intercompany prices for the tangible goods transaction between HSAG and HSI produce arm's-length results. HSI is the tested party, and operating margin on net resales is the profit level indicator.
5.3 Tested Party Selection
HSI has been selected as the tested party for the CPM/TNMM analysis of the tangible goods transaction. The selection of HSI is based on the following considerations:
(a) Least Complex Entity. As established in the functional analysis (Section 3), HSI is the least complex entity in the controlled transaction. HSI performs routine distribution, marketing, and design-support functions and does not own or control the critical value-driving intangible assets.
(b) Limited-Risk Distributor. HSI's functional profile—importing semiconductor products from a related-party supplier, warehousing finished goods, and reselling to unrelated customers with ancillary design-support and marketing activities—is that of a limited-risk distributor. This is a well-recognized business model for which reliable comparable company data is readily available.
(c) Reliable Financial Data. HSI maintains detailed financial records under U.S. GAAP, audited by Gresham Whitfield LLP, which provide a reliable basis for computing the operating margin profit level indicator.
(d) Functional Comparability. HSI's functions and risk profile are most comparable to those of independent semiconductor distributors in the benchmark set, permitting reliable comparison.
HSAG was rejected as the tested party. HSAG is a complex, IP-rich, vertically integrated advanced-node semiconductor manufacturer and technology developer. There are no reliable comparables for an entity with HSAG's functional profile—specifically, no publicly traded companies whose primary business is the integrated development and fabrication of advanced-node (sub-10nm) semiconductor devices for automotive and industrial applications and that are not themselves parties to significant controlled transactions. Attempting to benchmark HSAG's profitability would introduce substantial and unacceptable unreliability into the analysis.
5.4 Profit Level Indicator
Operating margin on net resales, defined as operating income divided by net revenue, has been selected as the profit level indicator ("PLI") for the CPM/TNMM analysis.
The selection of operating margin as the PLI is supported by the following rationale:
(a) Operating margin is the most commonly used and widely accepted PLI for distribution activities under both the CPM (Treas. Reg. § 1.482-5(b)(4)) and the TNMM (OECD Guidelines ¶ 2.103).
(b) Operating margin appropriately captures the full value of HSI's distribution, marketing, and design-support functions, including all relevant operating costs.
(c) Unlike gross margin, operating margin is not materially affected by differences in cost classification between comparable companies. In particular, the treatment of design-support and applications engineering costs as either COGS or operating expenses varies among semiconductor distributors, making gross margin comparisons less reliable.
(d) Operating margin is computed from readily available and auditable financial data.
Alternative PLIs Considered and Rejected:
• Berry Ratio (Gross Profit / Operating Expenses). The Berry ratio was considered but rejected. HSI's cost of goods sold is dominated by intercompany purchases from HSAG, which means that the transfer price itself constitutes the primary component of the Berry ratio's denominator (indirectly, through its effect on the gross profit numerator) and its numerator. This circularity renders the Berry ratio unreliable for this transaction, as the ratio would largely reflect the transfer price rather than providing an independent measure of arm's-length profitability. See Treas. Reg. § 1.482-5(b)(4)(ii).
• Gross Margin. Gross margin was considered but rejec
