Exhibit 99.2

Explanatory Note

During the first quarter of 2011, Humana Inc. realigned its business segments to reflect its evolving business model. As a result, Humana reassessed and changed its operating and reportable segments effective with the filing of its Quarterly Report on Form 10-Q for the three months ended March 31, 2011. The Company currently manages and reports its operating results using the following segments: Retail, Employer Group, and Health and Well-Being Services. The Company also discloses results for Other Businesses. This Exhibit 99.2 has been revised from the “Item 6. Selected Financial Data” to Humana’s Annual Report on Form 10-K for the year ended December 31, 2010 (the “2010 Form 10-K”) to reflect retrospective application of the new segments and reclassified historical results to conform to the new presentation.

Material revisions to the 2010 Form 10-K resulting from the Company’s new business segment reporting are highlighted in blue font. It is important to note, however, that other disclosures originally included in the 2010 Form 10-K, unrelated to the Company’s new business segment reporting, have been repeated in this Exhibit 99.2 without updates that may have been made to those disclosures in subsequent filings with the SEC. The non-updated disclosures, made as of February 17, 2011, appear in black font. For updated disclosures to these sections, you should read this Exhibit 99.2 together with the Company’s SEC filings made after February 17, 2011, including Humana’s Quarterly Reports on Form 10-Q for the quarterly periods ended March 31, 2011 and June 30, 2011.
