ObjetAppeals Conference Preparation — Penterra (Matter 1018-00009) — February 28 Conference

Sylvia, Garrett, Leila —

I want to lay out our preparation plan for the Appeals conference now scheduled for **February 28, 2024**, at the IRS Appeals Office in Manhattan. The assigned Appeals Officer is **Noreen Castañeda**, who came on in January. As you all know, this is PPC's opportunity to present our defense of the **$380.4 million** in proposed adjustments across TY 2017–2020 (NOPA issued October 12, 2023; Formal Protest filed December 22, 2023). We need to be airtight — on substance and logistics both. I'm setting out assignments, deadlines, and key themes below.

**ATTENDEES**

Confirmed attendees for February 28:

- **Calderwood & Harkness:** Leonard Cross, Sylvia Hartwell, Garrett Simmons - **PPC:** Marcus Whitfield (VP, Global Tax), Deborah Staines (General Counsel) - **Whitmore Valuation Group:** Dr. Helena Vasquez (Managing Director / Lead Economist) - **IRS:** Appeals Officer Noreen Castañeda (and possibly an IRS counsel representative)

Leila, you will not attend the conference itself but will be on standby at the Philadelphia office for real-time research support and available by phone throughout the day.

Garrett — please finalize and circulate the attendee list document by end of week.

**PRESENTATION — GARRETT**

Garrett, you are responsible for finalizing the Northgate Services Inc. presentation for the conference. The presentation should be organized by issue as follows:

1. **Case Overview and Factual Background** — PPC's IP structure, the CSA effective July 1, 2012, the PCT payment of $312M, PBI's role as IP holder and non-Americas principal.

2. **CSA Cost-Sharing Ratios** — PPC's positions (38.2%–42.7% across 2017–2020) vs. IRS's proposed increases (48.2%–53.7%), with the reasonably anticipated benefits methodology under Treas. Reg. § 1.482-7. Total CSA adjustments at issue: **$235.01M**.

3. **Legacy IP Royalty Rate** — PPC's 4.5% rate vs. IRS's proposed 11.0%. Whitmore's CUT analysis: 14 comparable pharmaceutical license agreements, IQR of 3.1%–6.8%, median 4.4%. Total royalty adjustments at issue: **$188.04M**. Correlative offset of **$42.65M**.

4. **PCT Valuation** — Whitmore's DCF/income method using 9.8% WACC supports $312M within arm's-length range of $278M–$361M; IRS used 7.2% WACC to arrive at $852M.

5. **PBI Economic Substance / DEMPE Functions** — 185 employees (up from 52 in 2012), 42 board meetings in Dublin (2017–2020), €47.2M cumulative regulatory spend, ~18,000 sq ft office at Sandyford Business Park, independent pricing decisions across 68 country markets, local banking with Glenmore Bank Ireland plc.

6. **Penalty Protection** — Contemporaneous documentation prepared by Crestfield & Associates under IRC § 6662(e)(3)(B); reasonable cause defense.

7. **Proposed Resolution Framework** — Our settlement posture (more on this below).

Please coordinate directly with **Dr. Vasquez** on her slides covering the economic analyses (CUT, CPM/TNMM, DCF). I know you sent her the updated data on February 10 — make sure her slides reflect those latest numbers.

**Deadline: Draft presentation to me and Sylvia by February 21** — that gives us a full week before the conference.

**DOCUMENT BINDERS — LEILA**

Leila, you are responsible for assembling the physical document binders for the conference. We need one per attendee — at least **6 copies plus 2 extras** for the IRS side. Each binder should be tabbed and indexed per the Table of Contents we've already prepared:

- **Tab 1:** Formal Protest (filed December 22, 2023) - **Tab 2:** Protest Exhibit A — PPC corporate structure chart (PPC → PHL → PBI → PMI) - **Tab 3:** Protest Exhibit B — Summary of CSA terms (effective date July 1, 2012, PCT $312M, cost-sharing percentages 2017–2020) - **Tab 4:** Protest Exhibit C — Summary of economic analyses (CUT, CPM/TNMM, DCF) - **Tab 5:** Protest Exhibit D — PBI economic substance evidence - **Tab 6:** Protest Exhibit E — Penalty protection documentation - **Tab 7:** Whitmore's CUT analysis report (14 comparables, IQR 3.1%–6.8%) - **Tab 8:** Whitmore's CPM/TNMM analysis (22 comparable companies) - **Tab 9:** Whitmore's PCT valuation / DCF report ($278M–$361M range) - **Tab 10:** Whitmore's WACC/Discount rate analysis (9.8% vs. IRS 7.2%) - **Tab 11:** Rebuttal of IRS Economist Dr. Washburne's analysis (prepared by Dr. Vasquez and Dr. Chakrabarti, January 2024) - **Tab 12:** Functional analysis of PBI (updated March 2023 version) - **Tab 13:** PBI personnel interview summaries (12 key employees) - **Tab 14:** PBI board minutes analysis (42 meetings) - **Tab 15:** DEMPE functions matrix - **Tab 16:** Key legal authorities (IRC § 482, Treas. Reg. §§ 1.482-4, 1.482-7, § 1.482-1(d); case law — *Altera*, *Harborview Corporation*, *Amazon*) - **Tab 17:** OECD Transfer Pricing Guidelines excerpts (Chapter VI, Chapter VIII) - **Tab 18:** Settlement range analysis (sensitivity analysis workbook, printed summary page)

**Deadline: Binders assembled and ready for my review by February 26** — two days before the conference.

Please confirm printing and binding logistics with our Philadelphia office support staff right away so we don't run into any last-minute bottlenecks.

**WITNESS AND SPEAKER PREPARATION**

Here is how I see the speaking roles at the conference:

- **Cross:** I will handle the opening presentation and lead the legal arguments — IRC § 482, arm's-length standard, best method rule, CSA defense, royalty rate defense, penalty protection, and the closing/settlement discussion.

- **Sylvia:** You'll address any procedural or engagement-level questions and manage the flow of Q&A. If Appeals Officer Castañeda raises settlement authority, you and I will handle that together.

- **Garrett:** You'll support me with factual and economic backup during the presentation, manage handouts and binder references in real time, and take detailed notes for our post-conference summary.

- **Dr. Vasquez:** She will present the economic analyses — CUT analysis, CPM/TNMM results, PCT DCF valuation, and rebuttal of Dr. Washburne's methodology. Garrett, the witness preparation memo for Dr. Vasquez is your responsibility — **due February 22**. Walk her through the anticipated questions on comparable selection methodology, discount rate assumptions, and specifically why the IRS's CUT choices and 7.2% WACC are flawed.

- **Marcus Whitfield:** Marcus may be called upon to speak to PPC's business rationale, PBI's operational role, and the company's transfer pricing compliance process. I am finalizing his witness prep memo — **target completion February 20**. Key messaging: PBI is a substantive entity making real commercial decisions, not a shell. PPC's transfer pricing positions were established in good faith based on arm's-length analysis and contemporaneous documentation.

- **Deborah Staines:** Deborah will attend in her capacity as General Counsel. She is not expected to present but should be prepared to address any governance or corporate-structure questions that come up.

**KEY ARGUMENTS — THEMES TO DRIVE HOME**

A brief reminder of the core themes we need to hammer at the conference:

1. PPC's **4.5% royalty rate** sits squarely within the arm's-length range (IQR 3.1%–6.8%, median 4.4%) based on 14 comparable uncontrolled transactions. The IRS's 11.0% rate is based on cherry-picked, non-comparable agreements.

2. PBI's **cost-sharing percentages (38.2%–42.7%)** accurately reflect reasonably anticipated benefits. The IRS's proposed increases of 8–12 percentage points are unsupported by the actual revenue data and projections.

3. The **$312M PCT payment** falls within the $278M–$361M arm's-length range using a properly risk-adjusted WACC of 9.8%. The IRS's 7.2% discount rate understates the risk inherent in pharmaceutical IP development.

4. **PBI has robust economic substance** — this is not a brass-plate entity. 185 employees, 42 board meetings, €47.2M in regulatory submissions, independent pricing across 68 markets. The DEMPE analysis clearly shows PBI controls key exploitation functions for non-Americas territories.

5. PPC maintained **contemporaneous documentation** for all four years, prepared by Crestfield & Associates. The § 6662(e) penalty is unsupportable — both on reasonable cause and documentation grounds.

**SETTLEMENT POSTURE**

As established in our December 10, 2023 memo, our target resolution is **10–15% of the $380.4M proposed adjustment**, with a **hard ceiling of 20%**. We should not initiate settlement discussion — let Appeals Officer Castañeda raise it. But if she does, we are prepared. Keep the sensitivity analysis workbook (modeled at 5%, 10%, 15%, 20%, 25% of the proposed adjustment) at hand for quick reference.
