Read decided not to move ahead with the merger after the US Treasury announced new measures that would block the tax benefits of the deal. For Read, it was the second major deal in two years to be blocked by a government. His attempt at buying the London-based drugmaker AstraZeneca for $118 billion was thwarted by British politicians in 2014. "Read shouldn't be the fall guy," Tony Scherrer, director of research at Smead Capital Management, told Reuters. STOCK ETFS SAW A SIXTH STRAIGHT WEEK OF INFLOWS.
