The key issue is that Lumileds itself is organized as a U.S. corporation; its current ownership is inconsequential, whether it&#x27;s a U.S. citizen or a Dutch conglomerate. CFIUS has had the legal authority to investigate -- and the president to block -- any transaction involving control of a U.S. company by a foreign national since the 1950s.<p>It&#x27;s worth noting that while (as far as I&#x27;m aware) there are relatively few CFIUS-equivalent <i>organizations</i> worldwide, most countries have some kind of mechanism for similar actions. That they rarely use them is a different issue entirely.
