[1] The income tax benefit in the first nine months of 2011 was unfavorably impacted because a portion of the charge for the impairment of the Regional Media Group’s goodwill was non-deductible.

[2] The income tax benefit for the first nine months of 2012 includes a tax deduction for goodwill, which was previously non-deductible, triggered upon the sale of the Regional Media Group.
