In that case, Google’s Q1 in the US is closer to $878 million in ad revenues, or more like 23% of the $3.86 billion from the IAB/PwC.

Similarly, Yahoo’s US Q1 ad revenues minus TAC is more like $728 million, or 19% of the whole.

Together, then Google and Yahoo’s US ad revenues are about 42%…a bit less than the 45% to 48% range you mention.

Hope that helps.
