The Organisation for Economic Co-operation and Development (“OECD”) and participating OECD member countries have issued rules introducing a 15% global minimum corporate tax rate for large multinational enterprise groups, also known as “Pillar Two.” These rules were amended in January 2026 by the OECD “Side-by-Side package” in particular to address the coexistence of U.S. minimum tax regimes and ensure that U.S. based multinational groups are not subject to both primary and secondary top-up taxes under Pillar Two. The adoption and effective dates of Pillar Two and any additional rules vary by country. However, Pillar Two has not had a material impact on our financial results for the six months ended June 30, 2026, and we do not expect Pillar Two to have a material impact on our financial results for the year ending December 31, 2026. We will continue to monitor and evaluate the impact of any developing legislation.
