1. BASIS OF PRESENTATION

The accompanying condensed consolidated financial statements are presented in accordance with generally accepted accounting principles for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all of the disclosures normally required by accounting principles generally accepted in the United States of America, or those normally made in an Annual Report on Form 10-K. For further information, the reader of this Form 10-Q should refer to our Form 10-K for the year ended December 31, 2010, that was filed with the Securities and Exchange Commission, or the SEC, on February 17, 2011 as retrospectively adjusted in our current report on Form 8-K filed with the SEC on October 20, 2011. We refer to the Form 10-K and Form 8-K collectively as the "2010 Form 10-K" in this document. References throughout this document to "we," "us," "our," "Company," and "Humana" mean Humana Inc. and its subsidiaries.

The preparation of our condensed consolidated financial statements in accordance with accounting principles generally accepted in the United States of America requires us to make estimates and assumptions that affect the amounts reported in the condensed consolidated financial statements and accompanying notes. The areas involving the most significant use of estimates are the estimation of benefits payable, the impact of risk sharing provisions related to our Medicare and TRICARE contracts, the valuation and related impairment recognition of investment securities, and the valuation and related impairment recognition of long-lived assets, including goodwill. These estimates are based on knowledge of current events and anticipated future events, and accordingly, actual results may ultimately differ materially from those estimates. Refer to Note 2 to the consolidated financial statements included in our 2010 Form 10-K for information on accounting policies that the Company considers in preparing its consolidated financial statements.

The financial information has been prepared in accordance with our customary accounting practices and has not been audited. In our opinion, the information presented reflects all adjustments necessary for a fair statement of interim results. All such adjustments are of a normal and recurring nature.

Realignment of Business Segments

During the first quarter of 2011, we realigned our business segments to reflect our evolving business model. We manage and report our operating results using the following segments: Retail, Employer Group, and Health and Well-Being Services. We also disclose results for Other Businesses. All respective amounts related to the segment change have been retrospectively adjusted throughout the financial statements. Our segment information is more fully described in Note 13.

As a result of changing our reportable segments, we also changed the classification of certain revenues and costs. Beginning January 1, 2011, costs of certain health and well-being services were reclassified as benefits expense including costs incurred by our wholly-owned mail order pharmacy from transactions with our members that were historically classified as selling, general and administrative (and now titled operating costs), as well as depreciation and amortization expenses. The effect of this reclassification is to account for the cost of providing these benefits to our members similarly whether the services are provided via a third party provider or internally through a stand-alone subsidiary. Likewise, co-share amounts from our members associated with our wholly-owned mail order pharmacy operations, historically classified as other revenue, are now classified as a reduction of benefits expense. The remaining items previously classified as other revenue, primarily consisting of patient service revenue associated with our Concentra Inc. subsidiary, which was acquired in December 2010, were combined with our previous administrative services fee revenue and are now classified as services revenue. Prior period amounts have been reclassified to conform to the new presentation. These adjustments had no impact on net income, cash flows or equity. Further, none of these adjustments impacted our regulated subsidiaries.

Depreciation and amortization expense associated with certain businesses in our Health and Well-Being Services segment delivering benefits to our members, primarily associated with our pharmacy operations, are now included with benefits expense. The amount of this expense was $7.9 million and $5.8 million for the three months ended September 30, 2011 and 2010, respectively. For the nine months ended September 30, 2011 and 2010, the amount of this expense was $24.6 million and $14.6 million, respectively.
