Major beat by the Chicago Manufacturing ISM, coming at 56.9, on expectations of 54, compared to 54.4 previous, and the highest since May 2010.

It is hurting our profit margins"; "Currency continues to wreak havoc with commodity pricing"; "Customers remain cautious, placing orders at the last minute, making supply planning a challenge."
