[1] As the Company was in a net loss position for the period from May 1, 2010 through March 31, 2011 and for the period from April 1, 2010 through April 30, 2010, there was no dilutive effect on net loss per common share as the Class P units issued by the predecessor and options issued by the successor are anti-dilutive. Therefore, both basic and diluted net loss per common share were $(0.60) for the period from May 1, 2010 through March 31, 2011 and $(5.11) for the period from April 1, 2010 through April 30, 2010.
