(1) As discussed in Note 13 – Segment Information, during the third quarter of 2011 we reorganized our FreedomFP line of business from our EM segment into our PBM segment. All amounts at December 31, 2010 and 2009 have been restated for comparability.

(2) Changes in other intangible assets are a result of the write-off of $11.0 million of deferred financing fees related to the credit facility terminated during 2010 and the capitalization of $3.9 million of deferred financing fees related to the new credit facility (see Note 8 – Financing).
