It's an unusual week at Deal Watch, as most of the largest deals this week were done by European companies.

This column highlights the largest deals that get done in any given week, and most of the time that listing has a distinctly American feel. That makes sense, given that the U.S. portion of the global M&A pie stands at roughly 48% of all targets in 2021. By comparison, the United Kingdom and China were second and third, respectively, with 9% and 6%.
