For example, nVidia's chips are made in Taiwan and Korea, and end up in devices sold globally. It's true that a large % of the assembly of circuit boards and electronic products are made in China. We make control system computers. It's very, very niche. Typically, what we sell to one equipment company, we can sell to others. It's very difficult for companies that are outside of the sub-supplier ecosystem to break in. The controllers are usually customized to some extent, then we sell a few hundred annually of that design. 'A few hundred a year' is a home run product.
