Segment Information

The results of our operations are described through three reportable segments: Commercial and Specialty Business, Government Business and Other, as further described in Note 20, “Segment Information,” to our audited consolidated financial statements as of and for the year ended December 31, 2013 included in our 2013 Annual Report on Form 10-K.

Effective January 1, 2014, our Employer Group Medicare Advantage members are being reported within Local Group and National Accounts in our Commercial and Specialty Business segment and prior period segment amounts have been reclassified to conform to the new presentation. These members were previously reported with our Medicare membership within our Government Business segment. The Employer Group Medicare Advantage members are retired members who have selected a Medicare Advantage product through our Local Group and National Accounts. Financial data by reportable segment for the three months ended March 31, 2014 and 2013 is as follows (amounts reported for prior periods have been reclassified to conform to our new segment reporting structure):
