Thank you so much for joining us.
We are at a crucial moment for the global economy because on Wednesday,
many businesses across the world will be dealing with new tariffs as the reciprocal ones announced by Donald Trump last week will come into effect.

but that they were bringing in a lot of revenue into the US.
