* Presidents of the Chicago Fed Charles Evans and Boston Fed Eric Rosengren on Monday took an aggressive stance on monetary policy, citing the U.S. economy's capacity to absorb an increase in rates.
* Their comments were in contrast with Fed Chair Janet Yellen's cautious tone on rates last week, given an uncertain global economy.

* Allergan shares fell 20.7 percent to $220 premarket after the U.S. Treasury Department unveiled rules aimed at curbing tax inversion deals, potentially derailing the drugmaker's $160 billion merger with Pfizer. Pfizer was up 2.4 percent at $31.45.
