Income Taxes
Our income tax provision for the three months ended March 31, 2015 includes a non-recurring deferred charge of $1.4 million related to an intercompany asset transfer. There have been no other significant changes to the relationship between pre-tax income and our income tax provision since the year ended December 31, 2014.
