Income Taxes 

The effective income tax rate related to continuing operations for the three months ended March 31, 2015 was 51.4% compared with 28.6% for the three months ended March 31, 2014.

An income tax benefit from an uncertain tax position may be recognized when it is more likely than not that the position will be sustained upon examination, based on technical merits, including resolutions of any related appeals or litigation processes. The unrecognized income tax benefit at March 31, 2015 was $14.5 million, including interest and penalties.  Within the next twelve months, it is reasonably possible that up to $0.1 million of unrecognized income tax benefits will be recognized upon settlement of tax examinations and the expiration of various statutes of limitations.
