tax, a concept raised just recently for -- i believe the first time was earlier this week when jean sperling, director of the white house economic council said, we need a global minimum tax so that people have the assurance that nobody is escaping doing their fair share as part of a race to the bottom. and then yesterday i believe in milwaukee the president said something similar, but not exactly the same when he said that from now on every multi national company should have to pay a basic minimum tax and every penny should go toward lowering taxes towards companies that hire in united states of america. this is a concept that is new to me. i'm curious as to whether or not you can shed any light as to what they're talking about, what you're seeking to accomplish, how it would work. just generally what is this global minimum tax we're starting to hear about? >> not as new as you think. when chairman kemp laid out his proposals for corporate tax reform last fall, i think, he proposed a global minimum tax to try to achieve the same objective, to make sure people can't take advantage of tax savi
