- Puerto Rico (manufacturing, Section 936 legacy structure)

In November 2015, Pfizer announced plans to acquire Allergan plc for approximately $160 billion in what would have been the largest pharmaceutical merger in history and a tax inversion — moving Pfizer's tax domicile from the U.S. to Ireland (Allergan's registered jurisdiction).

The U.S. Treasury Department issued new regulations in April 2016 specifically targeting "serial inverters" — companies that use successive inversions to achieve tax benefits. The rules:
- Increased the ownership threshold for inversions from 80% to 60%
- Targeted "serial inverters" like Allergan (which had inverted from Actavis)
- Restricted access to offshore cash through "earnings stripping" rules
On April 6, 2016, Pfizer terminated the Allergan merger, paying Allergan a $150 million termination fee.
The attempted inversion demonstrated Pfizer's intent to:
- Reduce U.S. corporate tax rate from 35% to Ireland's 12.5%
- Access approximately $150 billion in offshore cash without full U.S. taxation
- Shift IP and profit streams to lower-tax jurisdictions
Evidence:
- Wikipedia Corporate haven article: "IP-based Tax inversions" section specifically mentions "Apple vs. Pfizer–Allergan"
- Multiple news sources (2015-2016) documented the merger attempt
- Treasury regulations issued April 2016 specifically targeted this type of transaction

- Royalty Payments: Products manufactured in Ireland/Singapore, royalties flowing to IP holding entities
- U.S. statutory rate: 21% (post-TCJA 2017)
- Ireland effective rate: ~8-10% (with KDB)
- Puerto Rico effective rate: ~2-4% (Act 60)
- Blended offshore rate: ~6-9%
- Annual tax savings estimate: $2-4 billion (based on ~$30 billion offshore revenue base)
