MEMORANDUM
To: Leonard Cross, Responsible Partner Sylvia Hartwell, Billing Partner Garrett Simmons, Lead Associate
From: Leila Nazari, Working Associate
Date: November 10, 2023
Re: Analysis of IRS 30-Day Letter — Penterra Pharmaceuticals Corp. (EIN: 22-3741856), TY 2017–2020; IRS Exam Team LB&I-NE-TP-2022-00641
Matter No.: 1018-00009
I. Purpose and Executive Summary
The purpose of this memorandum is to analyze the 30-Day Letter issued by the Internal Revenue Service on November 8, 2023, in connection with the transfer pricing examination of Penterra Pharmaceuticals Corp. ("PPC" or the "Company") for tax years 2017, 2018, 2019, and 2020. This memorandum is intended to provide the engagement team with a comprehensive overview of the procedural posture, available options, applicable deadlines, and strategic considerations necessary to formulate a recommendation to PPC.
The 30-Day Letter accompanies the Notice of Proposed Adjustment ("NOPA") dated October 12, 2023, in which the IRS examination team proposed net adjustments of $380.4 million under Internal Revenue Code ("IRC") § 482 across the four tax years at issue. The proposed adjustments arise from two primary transfer pricing issues — cost-sharing ratio allocations under PPC's qualified cost-sharing arrangement ("CSA") with its Irish subsidiary, Penterra Biosciences Ireland Ltd. ("PBI"), and the royalty rate applicable to PBI's license of legacy intangible property — as well as a correlative offset allowed by the examination team to avoid double-counting. In addition, the NOPA proposes the imposition of the substantial valuation misstatement penalty under IRC § 6662(e) at the rate of 20%, resulting in an estimated penalty exposure of approximately $15.98 million.
The 30-Day Letter provides PPC with the right to protest the proposed adjustments to the IRS Independent Office of Appeals or, alternatively, to take no action at the examination level and await the issuance of a statutory notice of deficiency (commonly referred to as a "90-Day Letter") in order to petition the United States Tax Court. PPC may also agree to all or a portion of the proposed adjustments, though, as discussed below, agreement is not recommended at this stage.
This memorandum describes each of the procedural options available to PPC, identifies the applicable deadlines and statute-of-limitations considerations, evaluates the strategic implications of each option, and sets forth a recommended course of action together with an action plan and timetable for implementation.
Bottom-Line Recommendation: Based on the analysis set forth herein, the recommended course of action is that PPC file a formal written Protest to the IRS Independent Office of Appeals, contesting all proposed adjustments in their entirety. Given the complexity of the case — involving four tax years, net proposed adjustments of $380.4 million, two distinct transfer pricing methodologies, and substantial penalty exposure — we further recommend requesting an extension of the standard 30-day response deadline from December 8, 2023 to December 22, 2023, providing an additional 14 calendar days of preparation time. The extension request should be submitted by no later than November 15, 2023.
II. Background
A. The IRS Examination
The IRS Large Business & International Division ("LB&I") opened an examination of PPC on May 16, 2022, via Letter 2205-A, which served as the formal notification of examination for PPC's federal income tax returns (Forms 1120) for tax years 2017, 2018, 2019, and 2020. The examination was assigned to IRS Exam Team LB&I-NE-TP-2022-00641, operating within the LB&I Northeast Transfer Pricing Practice area. The team is led by Supervisory Revenue Agent Gerald Meskill and Lead Revenue Agent Patricia Dunleavy.
From the outset, the examination focused on PPC's intercompany transactions with PBI, the Company's principal Irish operating subsidiary. The IRS assigned Dr. Alan Washburne of the IRS Transfer Pricing Practice as the examining economist, reflecting the economic and analytical complexity of the issues under review. The IRS Office of Chief Counsel has provided legal support to the examination team throughout the audit, with Attorney-Advisor Franklin Rosario and Senior Counsel Donna Hirabayashi serving as the principal counsel advisors.
The tax years under examination are 2017, 2018, 2019, and 2020 — a four-year audit cycle covering the period during which PPC's Irish IP structure was fully operational and generating significant intercompany transactions. It should be noted that PPC was not enrolled in the IRS Compliance Assurance Process ("CAP") for any of the years at issue, and accordingly, the examination proceeded through the standard post-filing audit process.
Over the course of the examination, the IRS issued a total of 47 Information Document Requests ("IDRs") between June 2022 and September 2023. These IDRs covered a broad range of topics, including PPC's and PBI's functional analyses, the CSA documentation and reasonably anticipated benefit ("RAB") calculations, PBI's financial statements and board minutes, the platform contribution transaction ("PCT") valuation, comparable uncontrolled transaction ("CUT") and comparable profits method ("CPM") benchmarking studies, transfer pricing documentation prepared by PPC's independent auditor, and extensive factual information concerning PBI's operations, personnel, decision-making processes, and economic substance. PPC responded to all IDRs within the timeframes prescribed by the IRS or as extended by agreement, and the examination team did not issue any summonses or escalate any IDR enforcement actions.
A mid-examination conference between PPC and the IRS examination team was held on May 25, 2023, at which PPC's outside counsel and economic advisors presented PPC's positions on the key transfer pricing issues. Despite PPC's presentation, the examination team maintained its proposed positions, and the examination proceeded to the issuance of the NOPA.
B. The NOPA — October 12, 2023
On October 12, 2023, the IRS examination team issued the Notice of Proposed Adjustment ("NOPA") for all four tax years under examination. The NOPA identifies three categories of proposed adjustments, which together produce a net proposed adjustment of $380.40 million. Each category is described below.
CSA Cost-Sharing Ratio Adjustments — $235.01 Million Total. The first and largest category of proposed adjustments relates to PBI's cost-sharing percentage under the qualified cost-sharing arrangement between PPC and PBI. Under the terms of the CSA, PBI's share of the intangible development costs ("Coss") was determined based on RAB calculations that reflected PBI's proportionate share of the reasonably anticipated benefits from the covered intangibles being developed under the arrangement. PPC's contemporaneous RAB calculations established PBI's cost-sharing percentages at 38.2% (2017), 39.6% (2018), 41.1% (2019), and 42.7% (2020), reflecting PBI's increasing share of global revenues attributable to the covered intangibles.
The IRS examination team proposed increasing PBI's cost-sharing percentages by approximately 8 to 12 percentage points for each year, resulting in adjusted cost-sharing percentages of 48.2% (2017), 50.6% (2018), 52.3% (2019), and 53.7% (2020). The resulting proposed adjustments are as follows:
• Tax Year 2017: $48.73 million
• Tax Year 2018: $57.61 million
• Tax Year 2019: $62.85 million
• Tax Year 2020: $65.82 million
• Total CSA cost-sharing adjustments: $235.01 million
The IRS's position is that PBI's RAB shares should be higher because the examination team attributes greater future revenue potential to PBI's covered markets, relying in part on Dr. Washburne's analysis of market projections and growth rates that differ from those used by PPC in its contemporaneous documentation.
Legacy IP Royalty Rate Adjustments — $188.04 Million Total. The second category of proposed adjustments relates to the royalty rate paid by PBI to PPC for the license of certain pre-existing ("legacy") intangible property — specifically, the rights to manufacture and distribute PPC's branded pharmaceutical products in PBI's licensed territories. PPC's intercompany royalty rate was set at 4.5% of PBI's net sales in the licensed territories, based on a CUT analysis prepared by the Whitmore Valuation Group ("Whitmore") that identified comparable uncontrolled pharmaceutical licensing agreements.
The IRS examination team proposed increasing the royalty rate from 4.5% to 11.0% of PBI's net sales, resulting in proposed adjustments as follows:
• Tax Year 2017: $52.95 million
• Tax Year 2018: $49.55 million
• Tax Year 2019: $44.97 million
• Tax Year 2020: $40.57 million
• Total royalty rate adjustments: $188.04 million
The declining year-over-year adjustment amounts reflect the gradual transition of product revenue from the legacy IP category to the CSA-covered intangibles as PBI's portfolio shifted toward newer products developed under the cost-sharing arrangement. The IRS's proposed 11.0% royalty rate is based on a set of CUT agreements identified by Dr. Washburne that the IRS contends are comparable to PBI's license arrangement. As discussed in Section V below, PPC has strong grounds to challenge the comparability of the IRS's selected CUT agreements.
Correlative Offset — ($42.65 Million). The examination team allowed a correlative offset of $42.65 million to avoid double-counting between the CSA cost-sharing adjustments and the royalty rate adjustments. This offset reflects the recognition that an increase in PBI's cost-sharing percentage under the CSA partially overlaps with an increase in the royalty rate for legacy IP, insofar as both adjustments affect PBI's overall profit allocation. The correlative offset reduces the total gross proposed adjustments ($235.01M + $188.04M = $423.05M) to the net proposed adjustment of $380.40 million.
Net Proposed Adjustment: $380.40 Million.
Proposed Penalty. In addition to the proposed income adjustments, the NOPA proposes the imposition of the substantial valuation misstatement penalty under IRC § 6662(e). The penalty is calculated at the rate of 20% of the tax attributable to the § 482 allocation. Using the 21% corporate tax rate, the estimated penalty exposure is approximately $380.4 million × 21% × 20% = $15.98 million.
It should be noted that Tax Year 2017 implicates the pre-Tax Cuts and Jobs Act ("TCJA") corporate tax rate of 35% for the portion of the year prior to January 1, 2018. The NOPA applies the 21% rate uniformly across all four tax years, apparently for simplification purposes. This may require further analysis, as the actual tax liability for TY 2017 would be computed using the blended tax rate applicable to PPC's fiscal year that bridges the transition period. To the extent that the correct blended rate for TY 2017 exceeds 21%, both the deficiency and the penalty for that year would increase correspondingly. We recommend that this issue be examined as part of the Protest preparation process.
C. The 30-Day Letter — November 8, 2023
On November 8, 2023, Supervisory Revenue Agent Gerald Meskill issued the 30-Day Letter, formally titled as a preliminary notice letter, to PPC. The letter transmits the Revenue Agent's Report ("RAR") and the NOPA for all four tax years under examination and advises PPC of its rights and options in response to the proposed adjustments.
Specifically, the 30-Day Letter advises PPC that it may: (1) agree to the proposed adjustments in whole or in part by signing the enclosed consent forms; (2) file a formal written Protest requesting that the case be referred to the IRS Independent Office of Appeals for consideration; or (3) take no action within the 30-day period, in which case the examination will close on an unagreed basis and the IRS will proceed to issue a statutory notice of deficiency (90-Day Letter) under IRC § 6212, after which PPC would have the right to petition the United States Tax Court.
The 30-Day Letter establishes a 30-calendar-day window from the date of the letter for PPC to respond. As the letter is dated November 8, 2023, the initial response deadline is December 8, 2023.
III. Procedural Options Available to PPC
This section describes and evaluates each of the procedural options available to PPC in response to the 30-Day Letter. The options are presented in order of preference, with the recommended option described first.
A. Option 1: File a Formal Protest to IRS Appeals
Description. Under this option, PPC would file a written Protest within the 30-day window (or extended deadline, if granted) requesting that the case be referred to the IRS Independent Office of Appeals for de novo consideration of the proposed adjustments. The filing of a Protest initiates the administrative Appeals process, which provides PPC with a significant opportunity to resolve the dispute without the cost, delay, and uncertainty of judicial litigation.
Procedural Authority. The procedures governing the filing of a Protest and the conduct of Appeals proceedings are set forth in Revenue Procedure 2015-41 and in the Internal Revenue Manual at IRM 8.6.1 (Appeals Conference Procedures). Under these authorities, a taxpayer who receives a 30-Day Letter following an examination has the right to request consideration of the case by the IRS Independent Office of Appeals, which functions independently of the examination division and is charged with resolving tax controversies on a basis that is fair and impartial to both the government and the taxpayer.
Protest Requirements. The requirements for a formal written Protest are specified in Revenue Procedure 2015-41 and the Internal Revenue Manual. Because the proposed adjustment in this case vastly exceeds the $25,000 threshold for the filing of a "small case request" (the alternative to a formal Protest for smaller adjustments), PPC must file a formal Protest that includes each of the following elements:
(a) A written statement identifying the taxpayer — here, Penterra Pharmaceuticals Corp., Employer Identification Number 22-3741856 — and the tax periods at issue (TY 2017, 2018, 2019, and 2020).
(b) A statement of facts supporting PPC's positions, setting forth in detail the factual basis for PPC's disagreement with the proposed adjustments. This statement must be made under penalties of perjury for cases in which the proposed adjustment exceeds $25,000, as is the case here.
(c) A statement of law and argument explaining the legal and economic basis upon which PPC disagrees with each of the proposed adjustments, including citations to applicable statutory provisions, regulations, case law, and administrative guidance.
(d) Identification of each adjustment being contested, specifying the particular items in the RAR and NOPA with which PPC disagrees and the grounds for disagreement.
(e) A declaration by the person signing the Protest that the statements of fact contained therein are true, correct, and complete to the best of that person's knowledge and belief, made under penalties of perjury.
(f) The signature of PPC or its authorized representative, together with any required powers of attorney (Forms 2848).
Appeals Process Overview. Upon receipt of a properly filed Protest, the IRS examination team will transmit the case file — including the examination workpapers, the RAR, the NOPA, and PPC's Protest — to the IRS Independent Office of Appeals. The case will be assigned to an Appeals Officer with subject-matter expertise in transfer pricing. Based on our experience with LB&I transfer pricing cases in the Northeast region, we anticipate that the case would be assigned in January 2024. (We have subsequently learned that the case has been assigned to Appeals Officer Noreen Castañeda.)
The Appeals Officer will conduct an independent review of the case, considering the positions of both the examination team and the taxpayer. Unlike the examination team, which is tasked with determining the correct tax liability, the Appeals Officer is authorized to consider the "hazards of litigation" — that is, the likelihood of the government's success on each issue if the case were litigated in Tax Court. This hazards-of-litigation framework is the central analytical tool employed by Appeals and is a significant advantage for taxpayers with strong factual and economic positions.
Following the initial review, the Appeals Officer will schedule an Appeals conference, which is typically conducted in person at the Appeals office, or by telephone or video conference. At the Appeals conference, PPC and its representatives will have the opportunity to present PPC's positions, respond to the Appeals Officer's questions, and discuss potential settlement. The Appeals Officer may request additional information or analysis and may schedule multiple conferences.
Appeals has broad settlement authority and can settle the case on a basis different from the examination team's position. If a settlement is reached, it will be memorialized in a Form 906 Closing Agreement (if a final, binding resolution is intended) or a Form 870-AD (if a more limited agreement is appropriate). The settlement may address both the income adjustments and the proposed penalty.
If Appeals does not reach an acceptable resolution with PPC, the case will be returned to the examination division, and the IRS will proceed to issue a statutory notice of deficiency, at which point PPC would have the right to petition the Tax Court.
Advantages:
• Resolution without litigation. The Appeals process offers PPC the opportunity to resolve the dispute without the significant cost, delay, and uncertainty of Tax Court litigation. Appeals is widely recognized as the most cost-effective forum for resolving transfer pricing disputes, and the vast majority of transfer pricing cases are settled at the Appeals level.
• Settlement authority and hazards-of-litigation framework. Appeals Officers have explicit authority to settle cases based on their assessment of the hazards of litigation. This framework is highly favorable to taxpayers with strong positions, as it requires the Appeals Officer to weigh the likelihood that the IRS would prevail on each issue if the case were tried in Tax Court.
• Strong factual and economic record. PPC's positions are supported by a robust factual and economic record, including the functional analysis of PBI's operations, the Whitmore benchmarking studies (CUT analysis, CPM/TNMM analysis, and DCF valuation), and contemporaneous transfer pricing documentation prepared by Crestfield & Associates. This evidentiary package positions PPC well for a favorable settlement at Appeals.
• Preservation of Tax Court rights. Filing a Protest does not waive PPC's right to petition the Tax Court. If Appeals does not produce an acceptable resolution, PPC retains the right to receive a statutory notice of deficiency and petition for judicial review. The Appeals process thus represents an additional administrative layer of review, not a substitute for judicial review.
• Penalty abatement potential. Full or partial abatement of the proposed substantial valuation misstatement penalty under IRC § 6662(e) is possible at the Appeals level. PPC's contemporaneous transfer pricing documentation, prepared annually by Crestfield & Associates, provides a strong basis for a reasonable-cause defense under IRC § 6662(e)(3)(B). Appeals Officers have the authority to consider reasonable-cause defenses and to abate penalties accordingly.
• No prepayment required. Unlike the refund suit path (which requires full payment of the asserted deficiency followed by a claim for refund and suit in the United States District Court or Court of Federal Claims), the Appeals process does not require PPC to prepay the disputed tax amount. PPC's cash flow and liquidity are preserved throughout the administrative review.
Disadvantages:
• Disclosure of legal and factual positions. The formal Protest requires PPC to set forth its complete legal and factual positions, including its economic analyses and legal arguments, in a written submission that becomes part of the administrative case file. While the Protest is not a public document, it will be shared with the Appeals Officer and, in most cases, with the IRS examination team and Office of Chief Counsel. This disclosure may reveal litigation strategy to the IRS in the event the case proceeds to Tax Court.
• No formal discovery or evidentiary process. The Appeals process is an administrative proceeding, not a judicial one. There is no formal discovery, no right to compel testimony or production of documents from the IRS, and no formal evidentiary rules. PPC's ability to challenge the IRS's factual and economic positions is limited to the information in the administrative record and the materials submitted with the Protest and at the Appeals conference.
• Binding nature of settlement. A settlement reached at Appeals is generally binding on both parties. Once PPC accepts and signs a closing agreement or Form 870-AD, the ability to reopen the issues is extremely limited. PPC must therefore be confident in the terms of any settlement before agreeing.
B. Option 2: Take No Action at 30-Day Level; Wait for 90-Day Letter (Statutory Notice of Deficiency)
Description. Under this option, PPC would decline to file a Protest or otherwise respond to the 30-Day Letter. The examination would close on an unagreed basis, and the IRS would proceed to issue a statutory notice of deficiency (the "90-Day Letter") under IRC § 6212. The statutory notice of deficiency is a formal, jurisdictional prerequisite to the IRS's assessment of additional tax and is the mechanism by which PPC's right to pre-payment judicial review in the Tax Court is triggered.
Upon Receipt of the 90-Day Letter. Upon receiving the statutory notice of deficiency, PPC would have 90 days (or 150 days if the notice is addressed to a person outside the United States) to file a petition with the United States Tax Court under IRC § 6213(a). The filing of a timely petition stays the IRS's authority to assess the deficiency and initiates a judicial proceeding in which the Tax Court exercises jurisdiction to redetermine the correct amount of PPC's tax liability for the years at issue.
Tax Court Litigation Overview. Tax Court litigation involves a full judicial determination on the merits of the proposed adjustments. The proceedings are governed by the Tax Court Rules of Practice and Procedure and include the following phases:
• Pleading Phase. PPC files a petition setting forth its positions; the IRS files an answer.
• discovery Phase. Both parties engage in formal discovery, including interrogatories, document requests, depositions, and requests for admissions. Discovery in transfer pricing cases is typically extensive and may involve requests for voluminous economic data, internal communications, and expert analyses.
• Stipulation Process. The Tax Court requires the parties to stipulate to uncontested facts prior to trial to narrow the issues in dispute.
• Expert Witness Testimony. Transfer pricing cases invariably involve the testimony of expert economic witnesses. PPC and the IRS would each submit expert reports and potentially present live testimony at trial. The Whitmore Valuation Group's experts (Dr. Helena Vasquez and Dr. Rohan Chakrabarti) would serve as PPC's experts, while Dr. Washburne or other IRS economists would testify for the government.
• Trial. The case would proceed to trial before a Tax Court judge. Transfer pricing trials can extend over multiple weeks, depending on the complexity of the issues and the volume of evidence.
• Post-Trial Briefing and Opinion. Following trial, both parties submit post-trial briefs, and the Tax Court issues a written opinion and decision.
• Appeal. Either party may appeal the Tax Court's decision to the United States Court of Appeals for the circuit in which the taxpayer resides, which for PPC (headquartered in Princeton, New Jersey) would be the United States Court of Appeals for the Third Circuit.
The burden of proof in transfer pricing cases generally rests on the taxpayer, subject to the limited burden-shifting provisions of IRC § 7491. Under § 7491(a), the burden of proof may shift to the IRS if the taxpayer introduces credible evidence with respect to a factual issue and satisfies certain other requirements, including compliance with substantiation and record-keeping requirements. PPC's extensive contemporaneous documentation may support a burden-shifting argument, though this is fact-intensive and should be analyzed further.
The Tax Court provides exclusive pre-payment jurisdiction — that is, PPC may litigate the dispute without first paying the asserted deficiency. This is the principal jurisdictional advantage of the Tax Court over the alternative refund forums (District Court and Court of Federal Claims), both of which require full payment followed by a refund claim.
The timeline for Tax Court litigation is extended. Based on current docket conditions and the complexity of transfer pricing cases, PPC should expect a timeline of approximately two to five years from the filing of the petition to the issuance of a trial decision. This timeline does not include the possibility of an appeal to the Third Circuit, which could add an additional one to three years.
Advantages:
• Formal adjudication with full evidentiary process. Tax Court litigation provides PPC with a judicial forum in which the merits of the IRS's proposed adjustments are determined by an independent judge, with the benefit of formal discovery, expert testimony, and evidentiary rules. The Tax Court has deep expertise in transfer pricing matters and has issued numerous opinions addressing the methodologies and issues implicated by PPC's case.
• Binding judicial precedent. A Tax Court decision establishes binding precedent (subject to appeal) and resolves the disputed issues with finality. This may be valuable to PPC if the Company anticipates similar transfer pricing disputes in future audit cycles.
• Strategic option if Appeals fails. If Appeals does not produce an acceptable resolution, Tax Court litigation remains available as the ultimate backstop. Skipping Appeals and proceeding directly to Tax Court may be strategically appropriate in cases where the administrative process is unlikely to yield meaningful concessions. However, as discussed in Section V, we believe Appeals is likely to produce a favorable result for PPC, making this option unnecessary at this stage.
Disadvantages:
• Significant additional cost. Tax Court litigation in a transfer pricing case of this magnitude would involve substantial legal fees, expert witness fees (economic experts, valuation experts, and potentially industry experts), and significant management time devoted to discovery, trial preparation, and testimony. The total litigation cost could be expected to reach several million dollars, far exceeding the cost of resolution at the Appeals level.
• Extended uncertainty for financial reporting. PPC is publicly traded on the Nasdaq exchange (ticker: PPCA) and is subject to SEC reporting requirements. A prolonged, unresolved tax dispute of this magnitude would create extended uncertainty for PPC's financial statements. Under ASC 740-10 (formerly FIN 48), PPC is required to evaluate and disclose uncertain tax positions in its financial statements. PPC currently maintains a reserve of $62.4 million for uncertain tax positions related to the Irish IP structure. Extended litigation would require ongoing reassessment of this reserve, creating volatility in PPC's reported tax provision and effective tax rate.
• Credit facility implications. PPC's $1.5 billion revolving credit facility with Hargrove National Bank (Relationship Manager: Christine Bellucci) contains tax-indemnity and material-tax-event covenants. A proposed adjustment of $380.4 million could constitute a "material tax event" under the credit facility, and prolonged litigation would extend the period during which this issue remains outstanding. While filing a Protest and pursuing Appeals resolution should not, in our assessment, trigger default provisions (as the adjustment remains proposed and contested), extended Tax Court litigation increases the risk of covenant complications and may require more extensive communication with the lending syndicate.
• Institutional shareholder concerns. PPC's institutional shareholder base, including Ridgeview Capital Management LP (an 8.3% holder managed by Managing Partner Douglas Everett) and other significant institutional investors, monitors PPC's FIN 48 disclosures and tax contingency reporting. Extended Tax Court litigation increases the disclosure obligations and the uncertainty reflected in PPC's financial statements, potentially affecting investor confidence and stock price.
• Public nature of proceedings. Tax Court proceedings are public. The petition, pleadings, trial testimony, expert reports (to the extent admitted into evidence), and the Court's opinion are all part of the public record. Given PPC's status as a publicly traded company, the public nature of Tax Court litigation could attract media attention and affect PPC's reputation, particularly if the IRS's allegations regarding PBI's economic substance or the adequacy of PPC's transfer pricing are aired publicly.
• IRS appeal risk. Even if PPC prevails in the Tax Court, the IRS has the right to appeal the decision to the Third Circuit. The possibility of a government appeal extends the period of uncertainty and increases litigation costs. Transfer pricing cases are among the most frequently appealed categories of Tax Court decisions.
C. Option 3: Agree to Proposed Adjustments (Full or Partial)
Description. Under this option, PPC would sign the Revenue Agent's Report agreeing to all or a portion of the $380.4 million in proposed adjustments. PPC could agree to the full amount of the proposed adjustments, or it could partially agree — for example, conceding one category of adjustments while protesting another.
Assessment. Full agreement to the proposed adjustments is not recommended. PPC's transfer pricing positions are supported by substantial economic evidence and contemporaneous documentation, and the IRS's proposed adjustments are subject to significant challenge on multiple grounds. Specifically:
• PPC's CUT analysis, prepared by the Whitmore Valuation Group, establishes that the 4.5% royalty rate is within the interquartile range ("IQR") of 3.1% to 6.8% (median of 4.4%) identified from 14 comparable uncontrolled pharmaceutical license agreements. The IRS's proposed 11.0% rate is above the upper end of the IQR and appears to be based on CUT agreements that are distinguishable from PBI's license on comparability grounds.
• PPC's CPM/TNMM analysis demonstrates that PBI's profit margins fall within the arm's-length range established by 22 comparable companies, supporting the conclusion that PBI's transfer prices produce arm's-length results.
• Whitmore's discounted cash flow ("DCF") analysis of the PCT valuation establishes a range of $278 million to $361 million, within which PPC's $312 million payment falls. The IRS's challenge to the PCT valuation, based on a lower WACC of 7.2% (compared to Whitmore's 9.8%), is subject to challenge on discount rate methodology grounds.
• PBI's economic substance is well-documented and robust, as described in detail in Section V.A below.
Partial agreement — conceding certain issues while protesting others — could theoretically be considered for tactical purposes but would, in our judgment, weaken PPC's negotiating position at Appeals. Conceding any portion of the adjustments would signal to the Appeals Officer that PPC acknowledges some merit in the IRS's positions, potentially undermining PPC's ability to negotiate a favorable overall settlement. Moreover, because the CSA and royalty rate issues are economically interrelated (as reflected by the correlative offset), a partial concession on one issue could have cascading implications for the other.
This option is not recommended.
D. Option 4: Request a Conference with the Examination Team
Description. Under this option, PPC would request an additional conference with the IRS examination team prior to deciding whether to file a Protest. The purpose of such a conference would be to explore whether the examination team is willing to modify its positions in light of additional information or arguments from PPC.
Assessment. A mid-examination conference was already held on May 25, 2023, at which PPC and its advisors presented PPC's positions on the key transfer pricing issues. Despite this presentation, the examination team maintained its proposed positions and proceeded to issue the NOPA. The positions stated in the NOPA have been reviewed and approved by the IRS Office of Chief Counsel (Attorney-Advisor Franklin Rosario and Senior Counsel Donna Hirabayashi), and there is no indication that the examination team would be willing to revise its positions based on further discussions at this stage.
While requesting an additional conference is not precluded and could theoretically yield additional information about the IRS's positions, we do not believe it would change the outcome at the examination level. Further negotiation is significantly more productive at the Appeals level, where the Appeals Officer applies the hazards-of-litigation framework and has independent settlement authority.
This option is not recommended as a standalone course of action. However, PPC should not foreclose the possibility of informal communication with the examination team if opportunities arise that would benefit PPC's position without compromising the Protest strategy.
IV. Deadline Analysis
A. Initial Deadline
The 30-Day Letter is dated November 8, 2023. Under the standard 30-calendar-day response period, PPC's deadline to file a Protest or otherwise respond to the 30-Day Letter is December 8, 2023.
The 30-day period runs from the date of the letter, not the date of receipt. Although PPC may have received the letter one or two business days after November 8, 2023, the IRS measures the response period from the date on the face of the letter. Accordingly, December 8, 2023 is the operative deadline absent an extension.
B. Extension of Time
IRS practice and Internal Revenue Manual guidance generally permit extensions of the 30-day response period upon reasonable request by the taxpayer. Extensions are granted as a matter of administrative discretion and are routinely approved in complex cases involving large dollar amounts and multiple issues.
Recommendation. We recommend that PPC request an extension of the response deadline to December 22, 2023, providing an additional 14 calendar days beyond the standard December 8 deadline. This extended deadline will provide adequate time for the following critical preparation activities:
• Complexity of the case. The examination involves four tax years, $380.4 million in net proposed adjustments, two separate transfer pricing issues (CSA cost-sharing ratios and legacy IP royalty rates), a correlative offset, an economic substance challenge, and a penalty determination. The preparation of a comprehensive Protest addressing all of these issues requires substantial time for drafting, economic analysis, internal review, and quality control.
• Finalization of economic rebuttal analyses. The Whitmore Valuation Group (Dr. Helena Vasquez and Dr. Rohan Chakrabarti) must prepare formal rebuttal analyses responding to Dr. Washburne's economic report and must update and finalize the CUT, CPM/TNMM, and DCF analyses for inclusion as exhibits to the Protest. These economic analyses are central to PPC's position and must be prepared with the highest degree of rigor and precision.
• Client review. PPC's management — including CEO Harlan Whitfield, General Counsel Deborah Staines, and CFO Priya Iyer — must review the Protest before filing. In addition, PPC's independent auditor, Crestfield & Associates (engagement partner Martin Ogilvy and manager Susan Lam), must be consulted regarding the FIN 48 reserve implications of the Protest filing and the positions taken therein.
The extension request should be directed to Supervisory Revenue Agent Gerald Meskill, the lead signatory on the 30-Day Letter. The request should be submitted in writing, briefly explaining the basis for the extension and proposing the December 22, 2023 deadline. A separate letter requesting the extension should be prepared and filed promptly. The target submission date for the extension request is November 15, 2023, to ensure timely processing.
C. Statute of Limitations Considerations
The applicable statute of limitations for each tax year at issue must be considered in evaluating the response deadline and the overall timeline for the Appeals process.
Tax Year 2017. The standard three-year statute of limitations under IRC § 6501(a) for TY 2017, measured from the April 2018 filing date of PPC's Form 1120, would have expired in April 2021. However, PPC executed Form 872 (Consent to Extend the Time to Assess Tax) extending the statute of limitations for TY 2017 through December 31, 2024.
Tax Year 2018. A similar Form 872 extending the statute of limitations for TY 2018 through December 31, 2024 has been executed.
Tax Years 2019 and 2020. These tax years remain within the standard three-year assessment periods, though extensions may also be on file. The standard statute for TY 2019 would expire in approximately April or October 2023 (depending on filing date and any automatic extensions), and for TY 2020, in approximately April or October 2024. The examination team may have requested statute extensions for these years as well. The current status of the statute for TY 2019 and TY 2020 should be confirmed with PPC and documented.
Impact of Extension Request. The requested extension of the Protest filing deadline from December 8, 2023 to December 22, 2023 does not implicate statute-of-limitations concerns for any of the tax years at issue. All four years remain open through at least December 31, 2024 under the executed Forms 872 (for TY 2017 and 2018) and the standard assessment periods (for TY 2019 and 2020, assuming extensions have been executed as needed). The filing of the Protest will initiate the Appeals process, which will proceed within the remaining statute period.
However, ongoing monitoring of the statute of limitations is critical. As the December 31, 2024 expiration date for TY 2017 and TY 2018 approaches, PPC may be asked to execute additional Forms 872 to extend the statute through the anticipated conclusion of the Appeals process. The decision to extend the statute should be carefully considered in light of the strategic implications. Continuation of the matter through the statute-of-limitations tracker maintained by the engagement team is recommended.
V. Strategic Considerations and Recommendation
A. Strength of PPC's Positions
A critical factor in evaluating the recommended course of action is the strength of PPC's substantive positions on each of the issues raised in the NOPA. Based on the work performed to date, we believe PPC has strong positions on all of the major issues, which significantly enhances the prospect of a favorable resolution at the Appeals level.
CSA Cost-Sharing Ratios. PBI's cost-sharing percentages of 38.2% (2017), 39.6% (2018), 41.1% (2019), and 42.7% (2020) are supported by contemporaneous reasonably anticipated benefit ("RAB") calculations prepared by Crestfield & Associates as part of PPC's annual transfer pricing documentation. These RAB calculations were based on detailed financial projections and market analyses that reflect PBI's proportionate share of the anticipated benefits from the covered intangibles being developed under the CSA. The RAB methodology was validated by the Whitmore Valuation Group's independent CPM/TNMM analysis, which benchmarked PBI's results against 22 comparable companies and confirmed that PBI's cost-sharing contributions and profit allocation are consistent with arm's-length outcomes.
The IRS's proposed increases of 8 to 12 percentage points to PBI's cost-sharing percentages are based on Dr. Washburne's alternative RAB analysis, which employs higher revenue growth projections for PBI's covered markets and different assumptions regarding the allocation of residual profits. However, the IRS's proposed cost-sharing percentages lack comparability support. Dr. Washburne's analysis relies on market projections that were not available at the time the CSA contributions were determined and does not adequately account for the risks and uncertainties borne by PBI. We believe PPC's contemporaneous RAB calculations, prepared at the time of the cost-sharing determinations and based on the information reasonably available at that time, are more reliable and defensible than the IRS's hindsight-based alternative.
Legacy IP Royalty Rate. PPC's 4.5% royalty rate for PBI's license of legacy intangible property is within the interquartile range of 3.1% to 6.8% (median of 4.4%) identified by the Whitmore Valuation Group from a study of 14 comparable uncontrolled pharmaceutical license agreements. The CUT analysis was prepared contemporaneously with the establishment of the royalty rate and has been updated annually as part of PPC's transfer pricing documentation.
The IRS's proposed 11.0% royalty rate is based on a set of CUT agreements identified by Dr. Washburne that the IRS contends are comparable to PBI's license arrangement. However, we believe the IRS's CUT agreements are distinguishable on several comparability grounds, including differences in the scope and stage of development of the licensed intangibles, geographic market coverage, exclusivity provisions, the presence or absence of co-development obligations, and the allocation of regulatory risk. A detailed comparability analysis of the IRS's proposed CUTs, prepared by Whitmore, will be a central component of the Protest and the Appeals presentation.
PCT Valuation. The Whitmore Valuation Group's DCF analysis of the platform contribution transaction establishes a fair market value range of $278 million to $361 million for the pre-existing intangibles contributed to the CSA by PBI. PPC's PCT payment of $312 million falls within this range and is consistent with the arm's-length standard. The IRS's challenge to the PCT valuation is based on Dr. Washburne's use of a weighted average cost of capital ("WACC") of 7.2%, which is lower than the 9.8% WACC used by Whitmore. The lower WACC increases the present value of the anticipated income streams from the contributed intangibles, thereby increasing the required PCT payment.
We believe PPC has strong grounds to challenge the IRS's discount rate methodology. The 9.8% WACC used by Whitmore reflects the risk profile of PBI's intangible development activities, including the significant clinical, regulatory, and commercial risks associated with pharmaceutical product development. The IRS's 7.2% WACC understates these risks and appears to be based on a discount rate more appropriate for a diversified pharmaceutical company's overall operations rather than the specific risk profile of the intangibles contributed to the CSA. This issue is well-suited for expert testimony and economic analysis at Appeals.
Economic Substance. The NOPA raises concerns about the economic substance of PBI's operations. PBI's substance is, however, well-documented and robust. The key evidence supporting PBI's economic substance includes the following:
• PBI employed 185 full-time employees during the tax years at issue, including scientists, regulatory affairs specialists, supply chain managers, finance professionals, and commercial operations staff.
• PBI's board of directors held 42 board meetings in Dublin during the 2017–2020 period, reflecting active governance and decision-making at the Irish entity level.
• PBI incurred €47.2 million in regulatory expenditures during the period, reflecting PBI's direct involvement in obtaining and maintaining regulatory approvals in its licensed territories.
• PBI maintained a dedicated office of approximately 18,000 square feet at Sandyford Business Park in Dublin, serving as the operational headquarters for PBI's European and international commercial operations.
• PBI independently managed pricing across 68 country markets, exercising genuine commercial discretion in setting and negotiating prices with third-party distributors and national health authorities.
• PBI maintained independent banking arrangements with Glenmore Bank Ireland plc, including treasury management, foreign exchange hedging, and working capital facilities.
• PBI's managing director, Aidan Naughton, exercised genuine decision-making authority over PBI's commercial, regulatory, and operational activities, as documented through internal communications, board resolutions, and organizational charts.
This body of evidence establishes that PBI is a genuine operating entity with meaningful business activities, employees, assets, and decision-making authority — not a shell entity created solely for tax purposes. We believe PBI's economic substance provides a strong defense against the IRS's characterization of PBI as a mere conduit and supports the arm's-length nature of the intercompany transactions.
Penalty Protection. PPC maintained contemporaneous transfer pricing documentation prepared by Crestfield & Associates for all four tax years at issue. This documentation includes functional analyses, selection and application of the best method, identification of comparable transactions and companies, and documentation of the economic analysis supporting the arm's-length nature of PPC's intercompany prices. Under IRC § 6662(e)(3)(B), the substantial valuation misstatement penalty does not apply if the taxpayer establishes that the transfer pricing was determined in accordance with a reasonable method, applied consistently, and documented contemporaneously. PPC's documentation program satisfies these requirements and provides a strong basis for full abatement of the proposed penalty at Appeals.
B. Appeals as the Preferred Forum
The IRS Independent Office of Appeals applies a hazards-of-litigation framework in evaluating and settling cases. Under this framework, the Appeals Officer weighs the likelihood that the IRS would prevail on each issue if the case were litigated in Tax Court, considering the strengths and weaknesses of both the IRS's and the taxpayer's positions, the quality of the evidence, the applicable legal standards, and the potential outcomes.
Given the strength of PPC's economic analyses and PBI's economic substance evidence, as described in Section V.A above, PPC's positions present significant litigation hazards for the IRS. Specifically:
• PPC's royalty rate falls within the IQR of the Whitmore CUT study, which the IRS would need to overcome at trial by establishing the superiority of its own CUT agreements on comparability grounds — a factually intensive and uncertain endeavor.
• The IRS's proposed cost-sharing adjustments rely on alternative RAB calculations using higher growth projections, which are vulnerable to challenge as hindsight-based and inconsistent with the information available at the time the cost-sharing contributions were determined.
• PBI's robust economic substance record — 185 employees, 42 board meetings, €47.2 million in regulatory spending, independent management, and local banking — creates significant hazards for any IRS attempt to disregard or recharacterize PBI's role in the intercompany transactions.
• PPC's contemporaneous documentation provides a strong penalty defense, removing or substantially reducing the penalty exposure that the IRS might otherwise use as leverage in settlement negotiations.
Historical settlement patterns in transfer pricing Appeals cases suggest that resolutions are typically reached at a fraction of the proposed adjustments where the taxpayer has strong contemporaneous documentation, credible economic evidence, and well-developed legal arguments. While each case is unique, PPC's evidentiary package — including the Whitmore expert analyses (CUT, CPM/TNMM, and DCF), the functional analysis of PBI's operations, and the contemporaneous transfer pricing documentation — provides a compelling and comprehensive presentation for the Appeals Officer.
For these reasons, we believe Appeals is the preferred forum for resolving this dispute, offering the best combination of cost-effectiveness, timeliness, and likelihood of a favorable outcome.
C. Financial and Reporting Considerations
FIN 48 / ASC 740-10 Reserve. PPC currently maintains a reserve of $62.4 million for uncertain tax positions under ASC 740-10 (formerly FIN 48) related to the Irish IP structure. The issuance of the 30-Day Letter and the accompanying NOPA constitute a significant development in the evaluation of PPC's uncertain tax positions and trigger a reassessment of the reserve for year-end 2023 financial reporting purposes.
A decision to protest the proposed adjustments (rather than agree to them) signals continued uncertainty regarding the ultimate resolution of the disputed issues. The FIN 48 reserve must reflect PPC's assessment of the probable outcome, taking into account the proposed adjustments, the strength of PPC's positions, and the anticipated course of the administrative and potential judicial proceedings. Coordination with Crestfield & Associates — specifically, engagement partner Martin Ogilvy and manager Susan Lam — is essential to ensure that the reserve analysis is updated in a timely and accurate manner for inclusion in PPC's year-end 2023 financial statements.
The engagement team should work closely with PPC's tax department and Crestfield & Associates to evaluate whether the existing $62.4 million reserve remains adequate or requires adjustment in light of the NOPA and the decision to protest. The analysis should consider the full range of potential outcomes, including full concession, full abatement, and various settlement scenarios.
SEC Disclosure. PPC's upcoming 10-K filing for fiscal year 2023 must address the IRS examination and the NOPA as a contingent liability under ASC 450 (formerly SFAS 5) and must include appropriate disclosures regarding the uncertain tax positions under ASC 740-10. The decision to protest the proposed adjustments rather than proceed directly to Tax Court litigation affects the nature and extent of the required disclosure, as the filing of a Protest indicates that PPC is pursuing administrative resolution and has not yet exhausted its administrative remedies.
PPC's General Counsel, Deborah Staines, should be consulted regarding the SEC disclosure implications of the Protest filing and the characterization of the IRS dispute in PPC's public filings. The engagement team should coordinate with PPC's outside securities counsel, if applicable, to ensure that all disclosures are accurate and consistent with PPC's litigation strategy.
Credit Facility. PPC's $1.5 billion revolving credit facility with Hargrove National Bank contains tax-indemnity and material-tax-event covenants. A proposed adjustment of $380.4 million, if ultimately sustained, could constitute a "material tax event" under the credit facility agreement. However, we believe that the filing of a Protest and the pursuit of Appeals resolution should not trigger default provisions under the credit facility, as the adjustment remains proposed and contested — it has not been assessed, and PPC has not agreed to any portion of the deficiency.
Nonetheless, the specific covenant language in the credit facility agreement should be reviewed carefully to confirm this assessment. The engagement team should coordinate with PPC's CFO, Priya Iyer, and PPC's banking counsel to analyze the relevant provisions and determine whether any notification or reporting obligations to the lending syndicate are triggered by the NOPA or the Protest filing. PPC's Relationship Manager at Hargrove National Bank, Christine Bellucci, may need to be informed of the dispute as a matter of relationship management, even if formal notification is not contractually required.
Shareholder Considerations. PPC's institutional shareholder base includes Ridgeview Capital Management LP, which holds approximately 8.3% of PPC's outstanding common stock and is managed by Managing Partner Douglas Everett. Ridgeview and other institutional shareholders closely monitor PPC's FIN 48 disclosures and tax contingency reporting as part of their ongoing assessment of PPC's financial health and risk profile.
A prompt and favorable resolution at the Appeals level would minimize the complexity and duration of PPC's FIN 48 disclosures, reduce the uncertainty reflected in PPC's tax provision, and demonstrate effective management of PPC's tax risk. Conversely, extended Tax Court litigation would require ongoing disclosure of the dispute and its potential financial impact, increasing the uncertainty visible to shareholders and potentially affecting PPC's stock price and investor relations.
D. Coordination Requirements
The effective prosecution of PPC's Protest and Appeals case requires close coordination among multiple parties. The key coordination requirements are as follows:
Whitmore Valuation Group. Dr. Helena Vasquez and Dr. Rohan Chakrabarti of the Whitmore Valuation Group should begin immediately preparing a formal rebuttal of Dr. Alan Washburne's economic analysis. The rebuttal should address Dr. Washburne's CUT selection and comparability analysis, his alternative RAB calculations and growth projections, and his WACC methodology for the PCT valuation. In addition, Whitmore should update and finalize all of its existing economic reports (CUT, CPM/TNMM, and DCF analyses) for inclusion as exhibits to the Protest and for use at the Appeals conference.
Whitmore's engagement is conducted under the Kovel letter referenced as 1018-00009-KV, which extends the attorney-client privilege and work-product protections to Whitmore's analyses performed at the direction of counsel. All communications with Whitmore regarding the Protest and Appeals strategy should be channeled through the engagement team to preserve these protections.
Thornbury & Keogh (Dublin). Ciarán Thornbury of Thornbury & Keogh, PPC's Irish tax counsel, should be promptly informed of the 30-Day Letter and the anticipated Protest filing. Coordination with Thornbury & Keogh is necessary to address the Irish tax implications of the IRS's proposed adjustments and to evaluate the potential applicability of the competent authority and mutual agreement procedure ("MAP") provisions under Article 25 of the United States–Ireland Income Tax Treaty (the "Treaty"). If the IRS's § 482 adjustments are ultimately sustained in whole or in part, PBI may be subject to double taxation absent correlative relief from the Irish Revenue Commissioners. The competent authority process provides a mechanism for resolving such double-taxation situations, but it must be initiated in a timely manner and coordinated with the domestic administrative proceedings.
Crestfield & Associates. Susan Lam and Martin Ogilvy of Crestfield & Associates, PPC's independent auditor, should be alerted to the 30-Day Letter and the Protest filing for two purposes. First, Crestfield must reassess PPC's FIN 48 reserve for year-end 2023 financial reporting, taking into account the NOPA and PPC's decision to contest the proposed adjustments. Second, Crestfield may need to provide supplemental data from the original transfer pricing documentation files (which Crestfield prepared for all four tax years) for use in the Protest and Appeals proceedings. Any requests for documentation or data from Crestfield should be routed through PPC's tax department to ensure proper coordination and privilege protection.
E. Recommended Course of Action
Based on the analysis set forth in this memorandum, we recommend the following course of action:
1. File a formal Protest to the IRS Independent Office of Appeals contesting all proposed adjustments ($380.4 million net) in their entirety. The Protest should address each of the three categories of proposed adjustments (CSA cost-sharing ratios, legacy IP royalty rate, and PCT valuation) as well as the proposed substantial valuation misstatement penalty under IRC § 6662(e). The Protest should set forth PPC's factual and legal positions with sufficient detail and rigor to establish a strong foundation for the Appeals conference, while being mindful of the strategic considerations associated with disclosing PPC's full litigation strategy.
2. Request an extension of the response deadline to December 22, 2023. A draft extension request letter should be prepared for Leonard Cross's signature and addressed to Supervisory Revenue Agent Gerald Meskill. The extension request should be filed by no later than November 15, 2023, to ensure timely processing.
3. Begin Protest preparation immediately. Drafting responsibilities should be assigned as follows: Garrett Simmons will lead the preparation of the factual statement and economic analysis summary sections of the Protest; Leila Nazari will draft the legal argument sections, including the statutory and regulatory analysis, case law discussion, and penalty defense; Leonard Cross and Sylvia Hartwell will provide strategic direction, review all drafts, and manage client communication throughout the Protest preparation process.
4. Engage Whitmore to prepare a formal rebuttal of Dr. Washburne's economic analysis and to update and finalize all economic reports (CUT, CPM/TNMM, and DCF) for use as Protest exhibits. Whitmore's engagement should proceed under the existing Kovel letter (reference 1018-00009-KV) to preserve privilege protections.
5. Coordinate with PPC management — specifically CEO Harlan Whitfield, General Counsel Deborah Staines, and CFO Priya Iyer — on the decision to protest, FIN 48 reserve implications, SEC disclosure obligations, and Hargrove National Bank credit facility covenant analysis. A strategy call with PPC management should be scheduled promptly.
6. Do not agree to any portion of the proposed adjustments at this stage. Full or partial agreement would undermine PPC's negotiating position and is not supported by the strength of PPC's factual and economic positions.
7. Do not waive the right to petition the United States Tax Court. PPC should preserve all options in the event that Appeals does not produce an acceptable resolution. The filing of a Protest is without prejudice to PPC's right to petition the Tax Court following the issuance of a statutory notice of deficiency.
