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.

2. RECENTLY ISSUED ACCOUNTING PRONOUNCEMENTS

In September 2011, the Financial Accounting Standards Board, or FASB, issued new guidance that will allow entities to first assess qualitative factors to determine whether it is necessary to perform the two-step quantitative goodwill impairment test. Previous guidance required an entity to test goodwill for impairment, on at least an annual basis, by comparing the fair value of a reporting unit with its carrying amount. If the fair value of a reporting unit is less than its carrying amount, then the second step of the test must be performed to measure the amount of the impairment loss, if any. Under the new guidance, we would not be required to calculate the fair value of a reporting unit unless we determine, based on the qualitative assessment, that it is more likely than not that its fair value is less than its carrying amount. The new guidance includes a number of events and circumstances for an entity to consider in conducting the qualitative assessment. The new guidance is effective, for us, beginning with annual and interim impairment tests performed in 2012. Early adoption is permitted, including for our 2011 annual impairment test which will be performed in the fourth quarter of 2011. We are currently evaluating the new guidance.

In July 2011, the FASB issued new guidance regarding how health insurers should recognize and classify fees mandated by The Patient Protection and Affordable Care Act and The Health Care and Education Reconciliation Act of 2010 (which we collectively refer to as the Health Insurance Reform Legislation). The Health Insurance Reform Legislation imposes a non-deductible annual fee on health insurers for each calendar year beginning on or after January 1, 2014. The guidance requires that the liability for the fee be estimated and recorded in full once qualifying insurance coverage is provided in the applicable calendar year in which the fee is payable with a corresponding deferred cost that is amortized to expense over the calendar year that it is payable. The new guidance is effective for us when the fee is initially imposed in calendar year 2014.

In June 2011, the FASB issued new guidance requiring the presentation of other comprehensive income in a statement presented with equal prominence to the other primary financial statements. The new guidance eliminates the current option to report other comprehensive income and its components in the statement of stockholders’ equity and requires one of two alternatives for the presentation of items of net income and other comprehensive income: (1) in a single continuous statement referred to as the statement of comprehensive income, or (2) in two separate, but consecutive statements. Under either alternative, each component of net income and each component of other comprehensive income, together with totals for each, as well as total comprehensive income would need to be displayed. The new guidance is effective for us, beginning with the filing of our Form 10-Q for the three months ending March 31, 2012, with retrospective application required. Early adoption is permitted. As the new guidance only affects the presentation of other comprehensive income, it will not have a material impact on our results of operations, financial condition, or cash flows.

In May 2011, the FASB issued new guidance intended to improve the comparability of fair value measurements presented and disclosed in financial statements prepared in accordance with accounting principles generally accepted in the United States of America and those prepared in accordance with international financial reporting standards. While the new guidance is largely consistent with existing fair value measurement principles, it expands existing disclosure requirements for fair value measurements and makes other amendments which could change how existing fair value measurement guidance is applied. The new guidance will be effective for us beginning with the filing of our Form 10-Q for the three months ending March 31, 2012. We are currently evaluating the impact of the adoption of this new guidance on our results of operations, financial condition, or cash flows.

In January 2010, the FASB issued new guidance that expanded and clarified existing disclosures about fair value measurements. Under the new guidance, we are required to disclose additional information about movements of assets among the three-tier fair value hierarchy, present separately (that is, on a gross basis) information about purchases, sales, issuances, and settlements of financial instruments in the reconciliation of fair value measurements using significant unobservable inputs (Level 3), and expand disclosures regarding the determination of fair value measurements. We adopted the new disclosure provisions during the year ended December 31, 2010, except for the gross disclosures regarding purchases, sales, issuances and settlements in the roll forward of activity in Level 3 fair value measurements which we adopted with the filing of our Form 10-Q for the three months ended March 31, 2011 as provided in Note 5.

There are no other recently issued accounting standards that apply to us or that will have a material impact on our results of operations, financial condition, or cash flows.

3. ACQUISITIONS

On December 21, 2010, we acquired Concentra Inc., or Concentra, a health care company based in Addison, Texas, for cash consideration of $804.7 million. During the first half of 2011, we accrued and paid $3.7 million related to the final determination of working capital that existed at the acquisition date and recorded immaterial adjustments to the acquisition date fair value of Concentra’s net tangible assets acquired with a corresponding adjustment to goodwill. Through its affiliated clinicians, Concentra delivers occupational medicine, urgent care, physical therapy, and wellness services to workers and the general public through its operation of medical centers and worksite medical facilities. The Concentra acquisition provides us entry into the primary care space on a national scale, offering additional means for achieving health and wellness solutions and providing an expandable platform for growth with a management team experienced in physician asset management and alternate site care. The total consideration of $808.4 million exceeded our estimated fair value of the net tangible assets acquired by approximately $724.5 million, of which we allocated $188.0 million to other intangible assets and $536.5 million to goodwill. The goodwill was assigned to the Health and Well-Being Services segment. The other intangible assets, which primarily consist of customer relationships and trade name, have a weighted average useful life of 13.7 years. Approximately $57.9 million of the acquired goodwill is deductible for tax purposes.

The results of operations and financial condition of Concentra have been included in our consolidated statements of income and consolidated balance sheets from the acquisition date. In connection with the acquisition, we recognized approximately $14.9 million of acquisition-related costs, primarily banker and other professional fees, as operating costs in the fourth quarter of 2010. The pro forma financial information assuming the acquisition had occurred as of January 1, 2009 was not material to our results of operations.

During the third quarter of 2011, we entered into definitive agreements to acquire the California-based Medicare Advantage health maintenance organizations (HMO) Arcadian Management Services, Inc. and MD Care, Inc. These companies, on a combined basis, serve Medicare Advantage HMO members in 15 U.S. states, and offer us an opportunity to expand our Medicare footprint and grow our Medicare enrollment. The closings of these acquisitions are subject to federal and/or state regulatory approvals.

We participate in a securities lending program where we loan certain investment securities for short periods of time in exchange for collateral, consisting of cash or U.S. Government securities, initially equal to at least 102% of the fair value of the investment securities on loan. Investment securities with a fair value of $8.1 million at September 30, 2011 and $54.0 million at December 31, 2010 were on loan as of those respective dates. At September 30, 2011, all collateral from lending our investment securities was in the form of cash which has been reinvested in money market funds.

Approximately 96% of our debt securities were investment-grade quality at September 30, 2011, with a weighted average credit rating of AA by S&P. Most of the debt securities that were below investment-grade were rated BB, the higher end of the below investment-grade rating scale. At September 30, 2011, 12% of our tax-exempt municipal securities were pre-refunded, generally with U.S. government and agency securities, and 23% of our tax-exempt securities were insured by bond insurers and had an equivalent S&P credit rating of AA exclusive of the bond insurers’ guarantee. Our investment policy limits investments in a single issuer and requires diversification among various asset types.

The recoverability of our residential and commercial mortgage-backed securities is supported by factors such as seniority, underlying collateral characteristics and credit enhancements. Our residential and commercial mortgage-backed securities at September 30, 2011 primarily were composed of senior tranches having high credit support, with 99% of the collateral consisting of prime loans. The weighted average credit rating of all commercial mortgage-backed securities was AA at September 30, 2011.

All issuers of securities we own that were trading at an unrealized loss at September 30, 2011 remain current on all contractual payments. After taking into account these and other factors previously described, we believe these unrealized losses primarily were caused by an increase in market interest rates and tighter liquidity conditions in the current markets than when the securities were purchased. At September 30, 2011, we did not intend to sell the securities with an unrealized loss position in accumulated other comprehensive income, and it is not likely that we will be required to sell these securities before recovery of their amortized cost basis. As a result, we believe that the securities with an unrealized loss were not other-than-temporarily impaired at September 30, 2011.

The detail of realized gains (losses) related to investment securities and included within investment income was as follows for the three and nine months ended September 30, 2011 and 2010:

Financial Liabilities

Our long-term debt is recorded at carrying value in our consolidated balance sheets. The carrying value of our long-term debt outstanding was $1,661.6 million at September 30, 2011 and $1,668.8 million at December 31, 2010. The fair value of our long-term debt was $1,837.5 million at September 30, 2011 and $1,746.5 million at December 31, 2010. The fair value of our long-term debt is determined based on quoted market prices for the same or similar debt, or, if no quoted market prices are available, on the current prices estimated to be available to us for debt with similar terms and remaining maturities.

6. MEDICARE PART D

We cover prescription drug benefits in accordance with Medicare Part D under multiple contracts with the Centers for Medicare and Medicaid Services, or CMS. The condensed consolidated balance sheets include the following amounts associated with Medicare Part D as of September 30, 2011 and December 31, 2010. Amounts included below relating to the 2010 contract year for the net risk corridor payable of $380.0 million and the CMS subsidies payable of $98.3 million at September 30, 2011 are expected to be settled in the fourth quarter of 2011.

As disclosed in Note 2 to the consolidated financial statements included in our 2010 Form 10-K, reinsurance and low-income cost subsidies represent funding from CMS in connection with the Medicare Part D program for which we assume no risk. Beginning in 2011, the Health Reform Legislation mandates consumer discounts of 50% on brand name prescription drugs for Part D plan participants in the coverage gap. These discounts are funded by CMS and pharmaceutical manufacturers while we administer the application of these funds. We account for these subsidies and discounts as a deposit in our consolidated balance sheets and as a financing activity in our consolidated statements of cash flows. We do not recognize premium revenues or benefit expense for these discounts or subsidies. We have included the payable associated with the funding of these discounts with CMS subsidies in the table above.

7. GOODWILL AND OTHER INTANGIBLE ASSETS

The realignment of our business segments and corresponding change in our reportable segments, more fully described herein in Note 13, resulted in a change in the composition of our reporting units, the unit of accounting for goodwill. Accordingly, we reassigned goodwill to our reporting units as of January 1, 2011 using the relative fair value approach. Changes in the carrying amount of goodwill, by our new reportable segments, for the nine months ended September 30, 2011 were as follows:

Dividends

In April 2011, our Board of Directors approved the initiation of a quarterly cash dividend policy. Declaration and payment of future quarterly dividends is at the discretion of the Board and may be adjusted as business needs or market conditions change.

The following table provides details of our dividend payments in 2011:


Record Date	Payment Date		Amount per Share		Total Amount
					(in millions)
6/30/2011		7/28/2011	$	0.25	$	41.5
9/30/2011		10/28/2011	$	0.25	$	40.7

In addition, in October 2011, our Board of Directors declared a cash dividend to stockholders of $0.25 per share payable on January 31, 2012 to stockholders of record on December 30, 2011.

Stock Repurchases

In April 2011, the Board of Directors replaced its previously approved share repurchase authorization of up to $250 million with a new authorization for repurchases of up to $1 billion of our common shares exclusive of shares repurchased in connection with employee stock plans. The new authorization will expire June 30, 2013. Under this share repurchase authorization, shares could be purchased from time to time at prevailing prices in the open market, by block purchases, or in privately-negotiated transactions, subject to certain regulatory restrictions on volume, pricing, and timing. During the nine months ended September 30, 2010, we repurchased 1.99 million shares in open market transactions for $100.0 million at an average price of $50.17 under the previously approved share repurchase authorization. During the nine months ended September 30, 2011, we repurchased 0.8 million shares in open market transactions for $52.6 million at an average price of $63.73 under the previously

approved share repurchase authorization and we repurchased 5.9 million shares in open market transactions for $438.9 million at an average price of $74.01 under the new authorization. As of October 31, 2011, the remaining authorized amount under the new authorization totaled $561.3 million.

In connection with employee stock plans, we acquired 0.8 million common shares for $48.7 million and 0.2 million common shares for $8.2 million during the nine months ended September 30, 2011 and 2010, respectively.

11. INCOME TAXES

The effective income tax rate was 36.3% for the three months ended September 30, 2011 compared to 36.8% for the three months ended September 30, 2010. For the nine months ended September 30, 2011, the effective tax rate was 36.5% compared to 37.0% for the nine months ended September 30, 2010. The higher tax rate for the nine months ended September 30, 2010 primarily was due to the cumulative adjustment associated with estimating the retrospective aspect of new limitations on the deductibility of annual compensation in excess of $500,000 per employee as mandated by the Health Insurance Reform Legislation.

12. GUARANTEES AND CONTINGENCIES

Government Contracts

Our Medicare products, which accounted for approximately 65% of our total premiums and services revenue for the nine months ended September 30, 2011, primarily consisted of products covered under the Medicare Advantage and Medicare Part D Prescription Drug Plan contracts with the federal government. These contracts are renewed generally for a calendar year term unless CMS notifies us of its decision not to renew by August 1 of the calendar year in which the contract would end, or we notify CMS of our decision not to renew by the first Monday in June of the calendar year in which the contract would end. All material contracts between Humana and CMS relating to our Medicare products have been renewed for 2012, and all of our product offerings filed with CMS for 2012 have been approved.

CMS uses a risk-adjustment model which apportions premiums paid to Medicare Advantage plans according to health severity. The risk-adjustment model pays more for enrollees with predictably higher costs. Under this model, rates paid to Medicare Advantage plans are based on actuarially determined bids, which include a process whereby our prospective payments are based on a comparison of our beneficiaries’ risk scores, derived from medical diagnoses, to those enrolled in the government’s original Medicare program. Under the risk-adjustment methodology, all Medicare Advantage plans must collect and submit the necessary diagnosis code information from hospital inpatient, hospital outpatient, and physician providers to CMS within prescribed deadlines. The CMS risk-adjustment model uses this diagnosis data to calculate the risk adjusted premium payment to Medicare Advantage plans. We generally rely on providers to code their claim submissions with appropriate diagnoses, which we send to CMS as the basis for our payment received from CMS under the actuarial risk-adjustment model. We also rely on providers to appropriately document all medical data, including the diagnosis data submitted with claims.

CMS is continuing to perform audits of various companies’ selected Medicare Advantage contracts related to this risk adjustment diagnosis data. These audits are referred to herein as Risk-Adjustment Data Validation Audits, or RADV audits. RADV audits review medical record documentation in an attempt to validate provider coding practices and the presence of risk adjustment conditions which influence the calculation of premium payments to Medicare Advantage plans.

On December 21, 2010, CMS posted a description of the agency’s proposed RADV sampling and payment adjustment calculation methodology to its website, and invited public comment, noting that CMS may revise its sampling and payment error calculation methodology based upon the comments received. We believe the audit and payment adjustment methodology proposed by CMS is fundamentally flawed and actuarially unsound. In essence, in

Humana Inc.

making the comparison referred to above, CMS relies on two interdependent sets of data to set payment rates for Medicare Advantage (MA) plans: (1) fee for service (FFS) data from the government’s original Medicare program; and (2) MA data. The proposed methodology would review medical records for only one set of data (MA data), while not performing the same exercise on the other set (FFS data). However, because these two sets of data are inextricably linked, we believe CMS must audit and validate both of them before determining the financial implications of any potential RADV audit results, in order to ensure that any resulting payment adjustment is accurate. We believe that the Social Security Act, under which the payment model was established, requires the consistent use of these data sets in determining risk-adjusted payments to MA plans. Furthermore, our payment received from CMS, as well as benefits offered and premiums charged to members, is based on bids that did not, by CMS design, include any assumption of retroactive audit payment adjustments. We believe that applying a retroactive audit adjustment after CMS acceptance of bids would improperly alter this process of establishing member benefits and premiums.

CMS has received public comments, including our comments and comments from other industry participants and the American Academy of Actuaries, which expressed concerns about the failure to appropriately compare the two sets of data. On February 3, 2011, CMS issued a statement that it was closely evaluating the comments it has received on this matter and anticipates making changes to the proposed methodology based on input it has received, although we are unable to predict the extent of changes that they may make.

To date, six Humana contracts have been selected by CMS for RADV audits for the 2007 contract year, consisting of one “pilot” audit and five “targeted” audits for Humana plans. We believe that the proposed methodology for these audits is actuarially unsound and in violation of the Social Security Act. We intend to defend that position vigorously. However, if CMS moves forward with implementation of the proposed methodology without changes to adequately address the data inconsistency issues described above, it would have a material adverse effect on our revenues derived from the Medicare Advantage program and, therefore, our results of operations, financial position, and cash flows.

Our Medicaid business, which accounted for approximately 2% of our total premiums and services revenue for the nine months ended September 30, 2011, consists of contracts in Puerto Rico and Florida, with the vast majority in Puerto Rico. Effective October 1, 2010, as amended in May 2011, the Puerto Rico Health Insurance Administration, or PRHIA, awarded us three contracts for the East, Southeast, and Southwest regions for a three year term through June 30, 2013.

The loss of any of the contracts above or significant changes in these programs as a result of legislative action, including reductions in premium payments to us, or increases in member benefits without corresponding increases in premium payments to us, may have a material adverse effect on our results of operations, financial position, and cash flows.

Our military services business, which accounted for approximately 10% of our total premiums and services revenue for the nine months ended September 30, 2011, primarily consists of the TRICARE South Region contract. The original 5-year South Region contract expired on March 31, 2009 and was extended through March 31, 2011. On October 5, 2010, we were notified that the Department of Defense, or DoD, TRICARE Management Activity, or TMA, intended to negotiate with us for an extension of our administration of the TRICARE South Region contract, and on January 6, 2011, an Amendment of Solicitation/Modification of Contract to the TRICARE South Region contract became effective. The Amendment added one additional one-year option period, Option Period IX (which runs from April 1, 2011 through March 31, 2012). The TMA exercised Option Period IX on March 17, 2011.

As required under the current contract, the target underwritten health care cost and underwriting fee amounts are negotiated separately. Any variance from the target health care cost is shared with the federal government. Accordingly, events and circumstances not contemplated in the negotiated target health care cost amount may have a material adverse effect on us. These changes may include an increase or reduction in the number of persons enrolled or eligible to enroll due to the federal government’s decision to increase or decrease U.S. military deployments.

the event government reimbursements were to decline from projected amounts, any failure to reduce the health care costs associated with these programs may have a material adverse effect on our results of operations, financial position, and cash flows.

In July 2009, we were notified by the DoD that we were not awarded the third generation TRICARE program contract for the South Region which had been subject to competing bids. We filed a protest with the Government Accountability Office, or GAO, in connection with the award to another bidder citing discrepancies between the award criteria and procedures prescribed in the request for proposals issued by the DoD and those that appear to have been used by the DoD in making its contractor selection. In October 2009, we learned that the GAO had upheld our protest, determining that the TMA evaluation of our proposal had unreasonably failed to fully recognize and reasonably account for the likely cost savings associated with our record of obtaining network provider discounts from our established network in the South Region. On February 25, 2011, TMA awarded the South Region contract to us. On March 7, 2011, the competing bidder filed a protest of the award with the GAO. Also on March 7, 2011, as provided in the Federal Acquisition Regulations, TMA issued a stop work order to us in connection with the award. On June 14, 2011, the GAO upheld the award of the contract to us and TMA subsequently lifted the stop work order. On June 21, 2011, the competing bidder filed a complaint in the United States Court of Federal Claims objecting to the award of the contract to us. On October 14, 2011, the Court upheld the award of the contract to us, and the competing bidder has until December 13, 2011 to appeal it to the Court of Appeals for the Federal Circuit. Ultimate disposition of the contract award is subject to the resolution of any additional actions the unsuccessful bidder may take.

Legal Proceedings and Certain Regulatory Matters

Provider Litigation

Humana Military Healthcare Services, Inc. (“Humana Military”) was named as a defendant in Sacred Heart Health System, Inc., et al. v. Humana Military Healthcare Services Inc., Case No. 3:07-cv-00062 MCR/EMT (the “Sacred Heart” Complaint), a purported class action lawsuit filed on February 5, 2007 in the U.S. District Court for the Northern District of Florida asserting contract and fraud claims against Humana Military. The Sacred Heart Complaint alleged, among other things, that, Humana Military breached its network agreements with a class of hospitals in six states, including the seven named plaintiffs, that contracted for reimbursement of outpatient services provided to beneficiaries of the DoD’s TRICARE health benefits program (“TRICARE”). The Complaint alleged that Humana Military breached its network agreements when it failed to reimburse the hospitals based on negotiated discounts for non-surgical outpatient services performed on or after October 1, 1999, and instead reimbursed them based on published CHAMPUS Maximum Allowable Charges (so-called “CMAC rates”). Humana Military denied that it breached the network agreements with the hospitals and asserted a number of defenses to these claims. The Complaint sought, among other things, the following relief for the purported class members: (i) damages as a result of the alleged breach of contract by Humana Military, (ii) taxable costs of the litigation, (iii) attorneys fees, and (iv) any other relief the court deems just and proper. Separate and apart from the class relief, named plaintiff Sacred Heart Health System Inc. requested damages and other relief for its individual claim against Humana Military for fraud in the inducement to contract. On September 25, 2008, the district court certified a class consisting of all institutional healthcare service providers in TRICARE former Regions 3 and 4 which had network agreements with Humana Military to provide outpatient non-surgical services to CHAMPUS/TRICARE beneficiaries as of November 18, 1999, excluding those network providers who contractually agreed with Humana Military to submit any such disputes with Humana Military to arbitration. On March 3, 2010, the Court of Appeals reversed the district court’s class certification order and remanded the case to the district court for further proceeding. On June 28, 2010, the plaintiffs sought leave of the district court to amend their complaint to join additional hospital plaintiffs. Humana Military filed its response to the motion on July 28, 2010. The district court granted the plaintiffs’ motion to join 33 additional hospitals on September 24, 2010. On October 27, 2010, the plaintiffs filed their Fourth Amended Complaint claiming the U.S. District Court for the Northern District of Florida has subject matter jurisdiction over the case because the allegations in the complaint raise a substantial question under federal law. The amended complaint asserts no other material changes to the allegations or relief sought by the plaintiffs. Humana Military’s Answer to the Fourth Amended Complaint was filed on November 30, 2010. We are currently involved in discovery on this matter, with trial currently scheduled for October 2012.

On March 2, 2009, in a case styled Southeast Georgia Regional Medical Center, et al. v. Humana Military Healthcare Services, Inc., the named plaintiffs filed an arbitration demand, seeking relief on the same grounds as the plaintiffs in the Sacred Heart litigation. The arbitration plaintiffs originally sought certification of a class consisting of all institutional healthcare service providers that had contracts with Humana Military to provide outpatient non-surgical services and whose agreements provided for dispute resolution through arbitration. Humana Military submitted its response to the demand for arbitration on May 1, 2009. The plaintiffs have subsequently withdrawn their motion for class certification. On June 18, 2010, plaintiffs submitted their amended arbitration complaint. Humana Military’s answer to the complaint was submitted on July 9, 2010. An arbitration trial was held from September 26, 2011 to October 7, 2011, and the parties are waiting for a decision.

Humana intends to defend each of these actions vigorously.

Internal Investigation

With the assistance of outside counsel, we are conducting an ongoing internal investigation related to certain aspects of our Florida subsidiary operations, and have voluntarily self-reported the existence of this investigation to CMS, the U.S. Department of Justice and the Florida Agency for Health Care Administration. Matters under review include, without limitation, the relationships between certain of our Florida-based employees and providers in our Medicaid and/or Medicare networks, practices related to the financial support of non-profit or provider access centers for Medicaid enrollment and related enrollment processes, and loans to or other financial support of physician practices. We have reported to the regulatory authorities noted above on the progress of our investigation to date, and intend to continue to discuss with these authorities our factual findings as well as any remedial actions we have taken or may take.

Other Lawsuits and Regulatory Matters

Our current and past business practices are subject to review or other investigations by various state insurance and health care regulatory authorities and other state and federal regulatory authorities. These authorities regularly scrutinize the business practices of health insurance and benefits companies. These reviews focus on numerous facets of our business, including claims payment practices, provider contracting, competitive practices, commission payments, privacy issues, utilization management practices, and sales practices, among others. Some of these reviews have historically resulted in fines imposed on us and some have required changes to some of our practices. We continue to be subject to these reviews, which could result in additional fines or other sanctions being imposed on us or additional changes in some of our practices.

On September 10, 2009, the Office of Inspector General, or OIG, of the United States Department of Health and Human Services issued subpoenas to us and our subsidiary, Humana Pharmacy, Inc., seeking documents related to our Medicare Part D prescription plans and the operation of RightSourceRx^®, our mail order pharmacy in Phoenix, Arizona. In July 2010, the government informed us that no additional materials will be sought pursuant to the subpoenas.

Humana Inc.

We also are involved in various other lawsuits that arise, for the most part, in the ordinary course of our business operations, including employment litigation, claims of medical malpractice, bad faith, nonacceptance or termination of providers, anticompetitive practices, improper rate setting, failure to disclose network discounts and various other provider arrangements, general contractual matters, intellectual property matters, and challenges to subrogation practices, certain of which may be styled as class-action lawsuits. We also are subject to claims relating to performance of contractual obligations to providers, members, and others, including failure to properly pay claims, improper policy terminations, challenges to our implementation of the Medicare Part D prescription drug program and other litigation. Under state guaranty assessment laws, we may be assessed (up to prescribed limits) for certain obligations to the policyholders and claimants of insolvent insurance companies that write the same line or lines of business as we do.

Personal injury claims and claims for extracontractual damages arising from medical benefit denials are covered by insurance from our wholly owned captive insurance subsidiary and excess carriers, except to the extent that claimants seek punitive damages, which may not be covered by insurance in certain states in which insurance coverage for punitive damages is not permitted. In addition, insurance coverage for all or certain forms of liability has become increasingly costly and may become unavailable or prohibitively expensive in the future.

We record accruals for such contingencies to the extent that we conclude it is probable that a liability has been incurred and the amount of the loss can be reasonably estimated. No estimate of the possible loss or range of loss in excess of amounts accrued, if any, can be made at this time regarding the matters specifically described above because the inherently unpredictable nature of legal proceedings may be exacerbated by various factors, including: (i) the damages sought in the proceedings are unsubstantiated or indeterminate; (ii) discovery is not complete; (iii) the proceeding is in its early stages; (iv) the matters present legal uncertainties; (v) there are significant facts in dispute; (vi) there are a large number of parties (including where it is uncertain how liability, if any, will be shared among multiple defendants); or (vii) there is a wide range of potential outcomes.

The outcome of any current or future litigation or governmental or internal investigations, including the matters described above, cannot be accurately predicted, nor can we predict any resulting penalties, fines or other sanctions that may be imposed at the discretion of federal or state regulatory authorities. Nevertheless, it is reasonably possible that any such penalties, fines or other sanctions could be substantial, and the outcome of these matters may have a material adverse effect on our results of operations, financial position, and cash flows and may affect our reputation.

13. SEGMENT INFORMATION

During the first quarter of 2011, we realigned our business segments to reflect our evolving business model. As a result, we reassessed and changed our operating and reportable segments in the first quarter of 2011 to reflect management’s new view of the business and to align our external financial reporting with our new operating and internal financial reporting model. Historical segment information has been retrospectively adjusted to reflect the effect of this change. Our new reportable segments and the basis for determining those segments are discussed below.

We currently manage our business with three reportable segments: Retail, Employer Group, and Health and Well-Being Services. In addition, we include businesses that are not individually reportable because they do not meet the quantitative thresholds in an Other Businesses category. These segments are based on a combination of the type of health plan customer and adjacent businesses centered on well-being solutions for our health plans and other customers, as described below. These segment groupings are consistent with information used by our Chief Executive Officer to assess performance and allocate resources.

Humana Inc.

to individuals. The Employer Group segment consists of Medicare and commercial fully-insured medical and specialty health insurance benefits, including dental, vision, and other supplemental health and financial protection products, as well as administrative services only products marketed to employer groups. The Health and Well-Being Services segment includes services offered to our health plan members as well as to third parties that promote health and wellness, including primary care, pharmacy, integrated wellness, and home care services. The Other Businesses category consists of our Military services, primarily our TRICARE South region contract, Medicaid, and closed-block long-term care businesses as well as our contract with CMS to administer the Limited Income Newly Eligible Transition (LI-NET) program.

Our Health and Well-Being Services intersegment revenues primarily relate to managing prescription drug coverage for members of our other segments through Humana Pharmacy Solutions^®, or HPS, and includes the operations of RightSourceRx^®, our mail order pharmacy business. These revenues consist of the prescription price (ingredient cost plus dispensing fee), including the portion to be settled with the member (co-share) or with the government (subsidies), plus any associated administrative fees. Service revenues related to the distribution of prescriptions by third party retail pharmacies in our networks are recognized when the claim is processed. Product revenues from dispensing prescriptions from our mail order pharmacies are recorded when the prescription or product is shipped. Our pharmacy operations, which are responsible for designing pharmacy benefits, including defining member co-share responsibilities, determining formulary listings, selecting and establishing prices charged by retail pharmacies, confirming member eligibility, reviewing drug utilization, and processing claims, act as a principal in the arrangement on behalf of members in our other segments. As principal, our Health and Well-Being Services segment reports revenues on a gross basis including co-share amounts from members collected by third party retail pharmacies at the point of service.

We present our consolidated results of operations from the perspective of the health plans. As a result, the cost of providing benefits to our members, whether provided via a third party provider or internally through a stand-alone subsidiary, is classified as benefits expense and excludes the portion of the cost for which the health plans do not bear responsibility, including member co-share amounts and government subsidies of $1.1 billion and $0.9 billion for the three months ended September 30, 2011 and 2010, respectively. For the nine months ended September 30, 2011 and 2010, these amounts were $3.1 billion and $2.6 billion, respectively.

Other than those described previously, the accounting policies of each segment are the same and are described in Note 2 to the consolidated financial statements included in our 2010 Form 10-K. Transactions between reportable segments consist of sales of services rendered by our Health and Well-Being Services segment, primarily pharmacy and behavioral health services, to our Retail and Employer Group customers. Intersegment sales and expenses are recorded at fair value and eliminated in consolidation. Members served by our segments often utilize the same provider networks, enabling us in some instances to obtain more favorable contract terms with providers. Our segments also share indirect costs and assets. As a result, the profitability of each segment is interdependent. We do not report total assets by segment since this is not a metric used to assess performance and allocate resources. We allocate most operating expenses to our segments. Certain corporate income and expenses are not allocated to the segments, including investment income not supporting segment operations, interest expense on corporate debt, and certain other corporate expenses. These items are managed at the corporate level. These corporate amounts are reported separately from our reportable segments and included with intersegment eliminations in the tables presenting segment results below.

Executive Overview

General

Headquartered in Louisville, Kentucky, Humana is a leading health care company that offers a wide range of insurance products and health and wellness services that incorporate an integrated approach to lifelong well-being. By leveraging the strengths of our core businesses, we believe that we can better explore opportunities for existing and emerging adjacencies in health care that can further enhance wellness opportunities for the millions of people across the nation with whom we have relationships.

Our industry relies on two key statistics to measure performance. The benefit ratio, which is computed by taking total benefit expenses as a percentage of premiums revenue, represents a statistic used to measure underwriting profitability. The operating cost ratio, which is computed by taking total operating costs as a percentage of total revenue less investment income, represents a statistic used to measure administrative spending efficiency.

2011 Business Segment Realignment

Business Segments

We currently manage our business with three reportable segments: Retail, Employer Group, and Health and Well-Being Services. In addition, we include other businesses that are not reportable because they do not meet the quantitative thresholds required by generally accepted accounting principles in an Other Businesses category. These segments are based on a combination of the type of health plan customer and adjacent businesses centered on well-being solutions for our health plans and other customers, as described below. These segment groupings are consistent with information used by our Chief Executive Officer to assess performance and allocate resources.

The Retail segment consists of Medicare and commercial fully-insured medical and specialty health insurance benefits, including dental, vision, and other supplemental health and financial protection products, marketed directly to individuals. The Employer Group segment consists of Medicare and commercial fully-insured medical and

specialty health insurance benefits, including dental, vision, and other supplemental health and financial protection products, as well as administrative services only products marketed to employer groups. The Health and Well-Being Services segment includes services offered to our health plan members as well as to third parties that promote health and wellness, including primary care, pharmacy, integrated wellness, and home care services. The Other Businesses category consists of our Military services, primarily our TRICARE South Region contract, Medicaid, and closed-block long-term care businesses as well as our contract with CMS to administer the LI-NET program.

The results of each segment are measured by income before income taxes. Transactions between reportable segments consist of sales of services rendered by our Health and Well-Being Services segment, primarily pharmacy and behavioral health services, to our Retail and Employer Group customers. Intersegment sales and expenses are recorded at fair value and eliminated in consolidation. Members served by our segments often utilize the same provider networks, enabling us in some instances to obtain more favorable contract terms with providers. Our segments also share indirect costs and assets. As a result, the profitability of each segment is interdependent. We do not report total assets by segment since this is not a metric used to assess performance and allocate resources. We allocate most operating expenses to our segments. Certain corporate income and expenses are not allocated to the segments, including investment income not supporting segment operations, interest expense on corporate debt, and certain other corporate expenses. These items are managed at the corporate level. These corporate amounts are reported separately from our reportable segments and included with intersegment eliminations.

Seasonality

Our Retail segment offers Medicare stand-alone prescription drug plans, or PDPs, under the Medicare Part D program. These plans provide varying degrees of coverage. Our quarterly Retail segment earnings and operating cash flows are impacted by the Medicare Part D benefit design and changes in the composition of our membership. The Medicare Part D benefit design results in coverage that varies as a member’s cumulative out-of-pocket costs pass through successive stages of a member’s plan period which begins annually on January 1 for renewals. These plan designs generally result in us sharing a greater portion of the responsibility for total prescription drug costs in the early stages and less in the latter stages. As a result, the PDP benefit ratio generally decreases as the year progresses. In addition, the number of low-income senior members as well as year-over-year changes in the mix of membership in our stand-alone PDP products affect the quarterly benefit ratio pattern.

2011 Highlights

Consolidated

•

We experienced favorable prior-period medical claims reserve development of approximately $34 million, or $0.13 per diluted common share, for the three months ended September 30, 2011 as compared to $84 million, or $0.31 per diluted common share, for the three months ended September 30, 2010. For the nine months ended September 30, 2011, we experienced favorable prior-period development of approximately $151 million, or $0.57 per diluted common share, compared to $194 million, or $0.72 per diluted common share, for the nine months ended September 30, 2010.

•

In April 2011, our Board of Directors approved the initiation of a quarterly cash dividend policy and we subsequently paid a cash dividend of $0.25 per share to stockholders of record on each of June 30, 2011 and September 30, 2011.

•

In addition, in April 2011, the Board of Directors replaced its previously approved share repurchase authorization of up to $250 million with a new authorization for repurchases of up to $1 billion. The new authorization will expire June 30, 2013. As of October 31, 2011, the remaining authorized amount under the new authorization totaled $561.3 million.

•

Our year-to-date comparisons are impacted by the $147.5 million write-down of deferred acquisition costs associated with our individual commercial medical policies during the nine months ended September 30, 2010 as discussed more fully in Note 18 to the consolidated financial statements included in our 2010 Form 10-K.

Retail

•

On April 4, 2011, CMS announced that Medicare Advantage payment rates will increase on average 0.4% sector-wide in 2012. We believe we effectively designed Medicare Advantage products based upon this level of rate increase while continuing to remain competitive compared to both the combination of original Medicare with a supplement policy as well as other Medicare Advantage competitors within our industry. In addition, we will continue to pursue our cost-reduction and outcome-enhancing strategies, including care coordination and disease management, which we believe will mitigate the adverse effects of the rates on our Medicare Advantage members. Nonetheless, there can be no assurance that we will be able to successfully execute operational and strategic initiatives with respect to changes in the Medicare Advantage program. Failure to execute these strategies may result in a material adverse effect on our results of operations, financial position, and cash flows.

•

Individual Medicare Advantage membership of 1,613,400 at September 30, 2011 increased 152,700 members, or 10.5%, from 1,460,700 at December 31, 2010 and increased 151,200, or 10.3%, from 1,462,200 at September 30, 2010 primarily due to a successful enrollment season associated with the 2011 plan year.

•

Individual Medicare stand-alone PDP membership of 2,478,100 at September 30, 2011 increased 807,800 members, or 48.4%, from 1,670,300 at December 31, 2010 and increased 789,900, or 46.8%, from 1,688,200 at September 30, 2010, primarily due to sales of our new lowest premium national stand-alone Medicare Part D prescription drug plan co-branded with Wal-Mart Stores, Inc., the Humana Walmart-Preferred Rx Plan, that we began offering for the 2011 plan year.

•

Our year-to-date Retail segment comparisons are impacted by the $147.5 million write-down of deferred acquisition costs associated with our individual commercial medical policies during the nine months ended September 30, 2010 as discussed above.

•

During the third quarter of 2011, we entered into definitive agreements to acquire the California-based Medicare Advantage health maintenance organizations (HMO) Arcadian Management Services, Inc. and MD Care, Inc. These companies, on a combined basis, serve approximately 79,000 Medicare Advantage HMO members in 15 U.S. states, and offer us an opportunity to expand our Medicare footprint and grow our Medicare enrollment. The closings of these acquisitions are subject to federal and/or state regulatory approvals.

Other Businesses

•

As more fully discussed in Note 12 to the condensed consolidated financial statements, on February 25, 2011, the TMA awarded the TRICARE South Region contract to us. On March 7, 2011, the competing bidder filed a protest of the award with the GAO. Also on March 7, 2011, as provided in the Federal Acquisition Regulations, TMA issued a stop work order to us in connection with the award. On June 14, 2011, the GAO upheld the award of the contract to us and TMA subsequently lifted the stop work order. On June 21, 2011, the competing bidder filed a complaint in the United States Court of Federal Claims objecting to the award of the contract to us. On October 14, 2011, the Court upheld the award of the contract to us, and the competing bidder has until December 13, 2011 to appeal it in the Court of Appeals for the Federal Circuit. As a result of the award of the TRICARE South Region contract to us, we no longer expect a goodwill impairment to occur during the second half of 2011. Ultimate disposition of the contract award is, however, subject to the resolution of any additional actions the unsuccessful bidder may take.

Health Insurance Reform

In March 2010, the President signed into law The Patient Protection and Affordable Care Act and The Health Care and Education Reconciliation Act of 2010 (which we collectively refer to as the Health Insurance Reform Legislation) which enact significant reforms to various aspects of the U.S. health insurance industry. While regulations and interpretive guidance on some provisions of the Health Insurance Reform Legislation have been issued to date by the Department of Health and Human Services (HHS), the Department of Labor, the Treasury Department, and the National Association of Insurance Commissioners, there are many significant provisions of the legislation that will require additional guidance and clarification in the form of regulations and interpretations in order to fully understand the impacts of the legislation on our overall business, which we expect to occur over the next several years.

Implementation dates of the Health Insurance Reform Legislation vary from as early as six months from the date of enactment, or September 23, 2010, to as late as 2018. The following outlines certain provisions of the Health Insurance Reform Legislation:

•

Changes effective for plan years beginning on or after September 23, 2010 included: elimination of pre-existing condition limits for enrollees under age 19, elimination of certain annual and lifetime caps on the dollar value of benefits, expansion of dependent coverage to include adult children until age 26, a requirement to provide coverage for preventive services without cost to members, new claim appeal requirements, and the establishment of an interim high risk program for those unable to obtain coverage due to a pre-existing condition or health status.

•

Effective January 1, 2011, minimum benefit ratios were mandated for all commercial fully-insured medical plans in the large group (85%), small group (80%), and individual (80%) markets, with annual rebates to policyholders if the actual benefit ratios, calculated in a manner prescribed by HHS, do not meet these minimums. Beginning in 2011, we accrued for rebates, based on the manner prescribed by HHS, with initial rebate payments to be made in mid-2012. Our benefit ratios reported herein, calculated from financial statements prepared in accordance with accounting principles generally accepted in the United States of America, or GAAP, differ from the benefit ratios calculated as prescribed by HHS under the Health Insurance Reform Legislation. The more noteworthy differences include the fact that the benefit ratio calculations prescribed by HHS are calculated separately by state and legal entity; reflect actuarial adjustments where the membership levels are not large enough to create credible size; exclude some of our health insurance products; include taxes and fees as reductions of premium; treat changes in reserves differently than GAAP; and classify rebate amounts as additions to incurred claims as opposed to adjustments to premiums for GAAP reporting.

•

Medicare Advantage payment benchmarks for 2011 were frozen at 2010 levels and beginning in 2012, additional cuts to Medicare Advantage plan payments will begin to take effect (plans will receive a range of 95% in high-cost areas to 115% in low-cost areas of Medicare fee-for-service rates), with changes being phased-in over two to six years, depending on the level of payment reduction in a county. In addition, beginning in 2011, the gap in coverage for Medicare Part D prescription drug coverage has begun to incrementally close.

•

Beginning in 2014, the Health Insurance Reform Legislation requires: all individual and group health plans to guarantee issuance and renew coverage without pre-existing condition exclusions or health-status rating adjustments; the elimination of annual limits on coverage on certain plans; the establishment of state-based exchanges for individuals and small employers (with up to 100 employees); the introduction of standardized plan designs based on set actuarial values; the establishment of a minimum benefit ratio of 85% for Medicare Advantage plans; and insurance industry assessments, including an annual premium-based assessment ($8 billion levied on the insurance industry in 2014 with increasing annual amounts thereafter), which is not deductible for income tax purposes.

The Health Insurance Reform Legislation also specifies required benefit designs, limits rating and pricing practices, encourages additional competition (including potential incentives for new market entrants) and expands eligibility for Medicaid programs. In addition, the law will significantly increase federal oversight of health plan premium rates and could adversely affect our ability to appropriately adjust health plan premiums on a timely basis. Financing for these reforms will come, in part, from material additional fees and taxes on us and other health insurers, health plans and individuals beginning in 2014, as well as reductions in certain levels of payments to us and other health plans under Medicare as described above.

In addition, certain provisions in the Health Insurance Reform Legislation tie Medicare Advantage premiums to the achievement of certain quality performance measures (Star Ratings). Beginning in 2012, Medicare Advantage plans with an overall Star Rating of three or more stars (out of five) will be eligible for a quality bonus in their basic premium rates. Initially quality bonuses were limited to the few plans that achieved four or more stars as an overall rating, but CMS has expanded the quality bonus to three Star plans for a three year period through 2014.

Notwithstanding successful efforts to improve our Star Ratings and other quality measures for 2012 and 2013 and the continuation of such efforts, there can be no assurances that we will be successful in maintaining or improving our Star Ratings in future years. Accordingly, our plans may not be eligible for full level quality bonuses, which could adversely affect the benefits such plans can offer, reduce membership and/or reduce profit margins.

As discussed above, implementing regulations and related interpretive guidance continue to be issued on several significant provisions of the Health Insurance Reform Legislation, and certain aspects of the Health Insurance Reform Legislation are also being challenged in federal court, seeking to limit the scope of or have all or portions of the Health Insurance Reform Legislation declared unconstitutional. Judicial proceedings are subject to appeal and could last for an extended period of time, and we cannot predict the results of any of these proceedings. Congress may also withhold the funding necessary to implement the Health Insurance Reform Legislation, or may attempt to replace the legislation with amended provisions or repeal it altogether. Given the breadth of possible changes and the uncertainties of interpretation, implementation, and timing of these changes, which we expect to occur over the next several years, the Health Insurance Reform Legislation could change the way we do business, potentially impacting our pricing, benefit design, product mix, geographic mix, and distribution channels. The response of other companies to the Health Insurance Reform Legislation and adjustments to their offerings, if any, could cause meaningful disruption in the local health care markets. Further, various health insurance reform proposals are also emerging at the state level. It is reasonably possible that the Health Insurance Reform Legislation and related regulations, as well as future legislative changes, in the aggregate may have a material adverse effect on our results of operations, including restricting revenue, enrollment and premium growth in certain products and market segments, restricting our ability to expand into new markets, increasing our medical and administrative costs, lowering our Medicare payment rates and increasing our expenses associated with the non-deductible federal premium tax and other assessments; our financial position, including our ability to maintain the value of our goodwill; and our cash flows. If the new non-deductible federal premium tax is imposed as enacted, and if we are unable to adjust our business model to address this new tax, there can be no assurance that the non-deductible federal premium tax would not have a material adverse effect on our results of operations, financial position, and cash flows.

We intend for the discussion of our financial condition and results of operations that follows to assist in the understanding of our financial statements and related changes in certain key items in those financial statements from year to year, including the primary factors that accounted for those changes.

Comparison of Results of Operations for 2011 and 2010

The following discussion primarily deals with our results of operations for the three months ended September 30, 2011, or the 2011 quarter, the three months ended September 30, 2010, or the 2010 quarter, the nine months ended September 30, 2011, or the 2011 period, and the nine months ended September 30, 2010, or the 2010 period.

Summary

Net income was $444.8 million, or $2.67 per diluted common share, in the 2011 quarter compared to $393.2 million, or $2.32 per diluted common share, in the 2010 quarter. Net income was $1.2 billion, or $7.24 per diluted common share, in the 2011 period compared to $992.1 million, or $5.84 per diluted common share, in the 2010 period. The increases during the 2011 quarter and period primarily were due to improved operating performance in the Retail and Health and Well-Being Services segments. Our diluted earnings per common share include the beneficial impact of favorable prior-period medical claims reserve development of approximately $0.13 per diluted common share for the 2011 quarter compared to $0.31 per diluted common share for the 2010 quarter and $0.57 per diluted common share for the 2011 period compared to $0.72 per diluted common share for the 2010 period. Net income for the 2010 period also included the negative impact of a $147.5 million ($0.55 per diluted common share) write-down of deferred acquisition costs associated with our individual commercial medical policies in our Retail Segment.

Premiums

Consolidated premiums increased $717.9 million, or 8.8%, from the 2010 quarter to $8.9 billion for the 2011 quarter, and increased $1.8 billion, or 7.3%, from the 2010 period to $26.5 billion for the 2011 period. The increases primarily were due to a $608.0 million, or 12.7%, and $1.7 billion, or 12.1%, year-over-year increase in Retail segment premiums for the 2011 quarter and period, respectively, partially offset by a decline in Employer Group segment premiums in the 2011 period. The increase in Retail segment premiums primarily resulted from higher average individual Medicare Advantage membership. The decrease in Employer Group segment premiums primarily resulted from lower average fully-insured commercial group medical membership. Average membership is calculated by summing the ending membership for each month in a period and dividing the result by the number of months in a period.

Services Revenue

Consolidated services revenue increased $227.3 million from the 2010 quarter to $356.2 million for the 2011 quarter. For the 2011 period, services revenue was $1.0 billion, an increase of $640.0 million, or 162.2%, compared to the 2010 period. The increases during the 2011 quarter and period were primarily the result of the increase in primary care services revenue in our Health and Well-Being Services segment, primarily as a result of the acquisition of Concentra on December 21, 2010.

Investment Income

Investment income totaled $91.9 million for the 2011 quarter, an increase of $4.6 million from the 2010 quarter, primarily due to higher interest rates. For the 2011 period, investment income totaled $272.6 million, an increase of $20.1 million from the 2010 period primarily reflecting higher interest rates as well as higher average invested balances as a result of the reinvestment of operating cash flow.

Benefit Expenses

Consolidated benefit expenses were $7.1 billion for the 2011 quarter, an increase of $505.3 million, or 7.6%, from the 2010 quarter. For the 2011 period, consolidated benefit expenses increased by $1.4 billion, or 7.1%, from the 2010 period to $21.8 billion. The increases were primarily due to a $369.8 million, or 9.5%, and $1.4 billion, or 11.8%, year-over-year increase in Retail segment benefit expenses in the 2011 quarter and period, respectively, primarily driven by an increase in the average number of Medicare members.

The consolidated benefit ratio was 80.7% for the 2011 quarter, decreasing 90 basis points from the 2010 period, and 82.2% for the 2011 period, decreasing 20 basis points from the comparable 2010 period primarily driven by a decline in the Retail segment benefit ratio, particularly for our individual Medicare Advantage products, partially offset by lower favorable prior-period medical claims reserve development in the 2011 quarter and period than in the 2010 quarter and period on a consolidated basis.

Operating Costs

Our segments incur both direct and shared indirect operating costs. We allocate the indirect costs shared by the segments primarily as a function of revenues. As a result, the profitability of each segment is interdependent.

Consolidated operating costs increased $359.3 million, or 35.8%, during the 2011 quarter compared to the 2010 quarter. For the 2011 period, consolidated operating costs increased $653.0 million, or 20.7%, compared to the 2010 period. The increases primarily were due to an increase in operating costs in our Health and Well-Being Segment as a result of the acquisition of Concentra on December 21, 2010, as well as an increase in operating costs in our Retail segment as a result of increased expenses associated with the Medicare sales season for 2012 offerings which began a month earlier than in the prior year. The 2010 period includes $147.5 million of operating costs for the write-down of deferred acquisition costs associated with our individual commercial medical policies in our Retail Segment.

The consolidated operating cost ratio for the 2011 quarter was 14.8%, an increase of 270 basis points from the 2010 quarter. For the 2011 period, the consolidated operating cost ratio was 13.9%, a 130 basis point increase from the 2010 period. The $147.5 million write-down of deferred acquisition costs in the 2010 period increased the operating cost ratio 60 basis points for the 2010 period. Excluding the impact of the write-down of deferred acquisition costs in 2010, the increases primarily reflect the greater percentage of our revenues derived from Concentra, acquired December 21, 2010, in our Health and Well-Being Services segment, which carries a higher operating cost ratio on external revenues than our other business segments, as well as an increase in the Retail segment operating cost ratio.

Depreciation and Amortization

Depreciation and amortization for the 2011 quarter totaled $66.7 million, an increase of $8.0 million, or 13.5%, from the 2010 quarter. Depreciation and amortization for the 2011 period totaled $200.6 million, an increase of $18.6 million or 10.2% from the 2010 period. The increases primarily reflect depreciation and amortization expense associated with our Concentra operations, acquired on December 21, 2010.

Interest Expense

Interest expense was $27.1 million for the 2011 quarter, increasing $0.9 million, or 3.5% from the 2010 quarter, and $82.0 million for the 2011 period, increasing $3.3 million, or 4.2%, from the 2010 period.

Income Taxes

Our effective tax rate during the 2011 quarter was 36.3% compared to the effective tax rate of 36.8% in the 2010 quarter. The effective tax rate for the 2011 period of 36.5% declined from 37.0% for the 2010 period. The higher tax rate for the 2010 period primarily was due to the cumulative adjustment associated with estimating the retrospective aspect of new limitations on the deductibility of annual compensation in excess of $500,000 per employee as mandated by the Health Insurance Reform Legislation.

Pretax Results

•

Retail segment pretax income was $541.4 million in the 2011 quarter, an increase of $93.5 million, or 20.9%, compared to $447.9 million in the 2010 quarter. For the 2011 period, the Retail segment’s pretax income was $1.3 billion compared to $1.0 billion in the 2010 period, an increase of $0.3 billion, or 21.5%. These increases were primarily driven by higher average individual Medicare membership and a lower benefit ratio, discussed below, partially offset by increased expenses associated with the Medicare sales season for 2012 offerings which began a month earlier than in the prior year. Pretax income for the 2010 period included the negative impact of a $147.5 million write-down of deferred acquisition costs associated with our individual commercial medical policies. In addition, the Retail segment’s pretax income for the 2011 quarter and period included the beneficial effect of an estimated $32 million and $104 million, respectively, in favorable prior-period medical claims reserve development versus $63 million and $165 million in the 2010 quarter and period, respectively.

Enrollment

•

Individual Medicare Advantage membership increased 151,200 members, or 10.3%, from September 30, 2010 to September 30, 2011 due to a successful enrollment season associated with the 2011 plan year.

•

Individual Medicare stand-alone PDP membership increased 789,900 members, or 46.8%, from September 30, 2010 to September 30, 2011 primarily from higher gross sales year-over-year, particularly due to our low-price-point Humana Walmart-Preferred Rx Plan that we began offering for the 2011 plan year.

•

Individual specialty membership increased 268,600, or 55.2%, from September 30, 2010 to September 30, 2011 primarily driven by increased sales in dental and vision offerings.

Premiums

•

Retail segment premiums increased $608.0 million, or 12.7%, from the 2010 quarter to the 2011 quarter and increased $1.7 billion, or 12.1%, from the 2010 period to the 2011 period. The increases primarily were due to a 10.0% increase for both the 2011 quarter and period in average individual Medicare Advantage membership compared to the 2010 quarter and period. Individual Medicare stand-alone PDP premium revenues increased $73.9 million, or 14.6%, during the 2011 quarter compared to the 2010 quarter and increased $224.9 million, or 14.9%, during the 2011 period compared to the 2010 period. These increases primarily were due to a 44.9% and 39.2% increase in average individual PDP membership for the 2011 quarter and period, respectively, compared to the 2010 quarter and period, partially offset by decreases in individual Medicare stand-alone PDP per member premiums for the same periods. This was primarily a result of sales of our low-price-point Humana Walmart-Preferred Rx Plan that we began offering for the 2011 plan year.

Benefit expenses

•

The Retail segment benefit ratio decreased 230 basis points from 81.0% in the 2010 quarter to 78.7% in the 2011 quarter. For the 2011 period, the Retail segment benefit ratio decreased 20 basis points to 81.9% from 82.1% for the 2010 period. The declines primarily reflect a lower Medicare Advantage benefit ratio due to lower cost trends arising out of our cost-reduction and outcome-enhancing strategies, including care coordination and disease management, as well as a significant increase in our individual Medicare stand-alone PDP membership in the 2011 quarter and period, partially offset by lower favorable prior-period medical claims reserve development in the 2011 quarter and period than in the 2010 quarter and period, respectively. As discussed previously, the individual Medicare stand-alone PDP product design carries a higher benefit ratio in the first quarter and the benefit ratio generally decreases as the year progresses. Favorable reserve development decreased the Retail segment benefit ratio by approximately 60 basis points and 70 basis points in the 2011 quarter and period, respectively, versus approximately 130 basis points and 120 basis points in the 2010 quarter and period, respectively.

Operating costs

•

The Retail segment operating cost ratio of 11.2% for the 2011 quarter increased 160 basis points from 9.6% for the 2010 quarter primarily reflecting increased expenses associated with the Medicare sales season for 2012 offerings which began a month earlier than in the prior year as well as a higher percentage of membership in individual Medicare stand-alone PDP products in light of the Humana Walmart-Preferred Rx Plan, first offered in 2011, which carry a higher operating cost ratio than other

Medicare products. The Retail segment operating cost ratio of 10.1% for the 2011 period decreased 40 basis points from 10.5% for the 2010 period. The $147.5 million write-down of deferred acquisition costs in the 2010 period increased the operating cost ratio 100 basis points for the 2010 period. Excluding the impact of the write-down of deferred acquisition costs, the increase in the operating cost ratio year-over-year primarily reflects the same factors impacting the quarter-over-quarter comparisons.

Pretax Results

•

Employer Group segment pretax income decreased $33.1 million, or 41.9%, from the 2010 quarter to $45.9 million in the 2011 quarter primarily due to a higher benefit ratio in the 2011 quarter as compared to the 2010 quarter. Employer Group segment pretax income increased $32.8 million, or 12.6%, from the 2010 period to $293.0 million for the 2011 period primarily due to a shift to a more profitable mix of membership. The Employer Group segment’s pretax income for the 2011 quarter and period included the beneficial effect of an estimated $9 million and $42 million, respectively, in favorable prior-period medical claims reserve development versus $21 million and $29 million in the 2010 quarter and period, respectively.

Enrollment

•

Fully-insured commercial group medical membership decreased 76,600 members, or 6.1%, from September 30, 2010 to September 30, 2011 primarily due to continued pricing discipline in a highly competitive environment for large group business partially offset by small group business membership gains.

•

Group ASO commercial medical membership decreased 173,300 members, or 11.9%, from September 30, 2010 to September 30, 2011 primarily due to continued pricing discipline in a highly competitive environment for self-funded accounts.

•

Group specialty membership decreased 83,400 members, or 1.3%, from September 30, 2010 to September 30, 2011 primarily due to the loss of dental ASO membership, partially offset by increased sales of vision and other supplemental benefit offerings.

Premiums

•

Employer Group segment premiums increased $7.9 million, or 0.4%, to $2.2 billion for the 2011 quarter, primarily due to an increase in fully-insured group Medicare Advantage membership, partially offset by lower average commercial group medical membership. For the 2011 period, Employer Group segment premiums decreased by $162.6 million, or 2.4%, from the 2010 period to $6.7 billion primarily due to lower average commercial group medical membership year-over-year, partially offset by an increase in group Medicare Advantage membership.

Benefit expenses

•

The Employer Group segment benefit ratio of 83.5% for the 2011 quarter increased 150 basis points from 82.0% for the 2010 quarter, primarily reflecting lower favorable prior-period medical claims reserve development in the 2011 quarter versus the 2010 quarter, growth in our group Medicare Advantage products which generally carry a higher benefit ratio than our fully-insured commercial group products, and the effect of rebates accrued in the 2011 quarter associated with the minimum benefit ratios required under the Health Insurance Reform Legislation. The Employer Group segment benefit ratio decreased 70 basis points from 81.8% in the 2010 period to 81.1% in the 2011 period primarily due to lower utilization of benefits year-over-year in our commercial group products. Favorable reserve development decreased the Employer Group segment benefit ratio by approximately 30 basis points and 60 basis points in the 2011 quarter and period, respectively, versus 100 basis points and 40 basis points in the 2010 quarter and period, respectively.

Operating costs

•

The Employer Group segment operating cost ratio of 17.5% for the 2011 quarter decreased 10 basis points from 17.6% for the 2010 quarter primarily reflecting administrative scale efficiencies associated with an increase in average fully-insured group Medicare Advantage membership. The Employer Group segment operating cost ratio of 17.5% for the 2011 period was unchanged from the 2010 period.

Pretax results

•

Health and Well-Being Services segment pretax income increased $8.0 million, or 10.6%, from the 2010 quarter to $83.6 million for the 2011 quarter. The segment’s pretax income for the 2011 period increased $93.1 million, or 53.3%, from the 2010 period to $267.7 million. The 2010 quarter was favorably impacted by a $22.3 million risk share adjustment to intersegment revenues associated with our CAC medical centers in connection with the Medicare risk adjustment settlement. Excluding the impact of the CAC medical centers adjustment, the increases in our quarterly and year-to-date comparisons primarily were due to growth in our pharmacy solutions business together with the addition of the Concentra business, acquired on December 21, 2010.

Primary care services revenue increased $230.1 million and $660.7 million from the 2010 quarter and period, respectively, to $230.5 million and $662.0 million for the 2011 quarter and period, respectively, primarily due to the acquisition of Concentra on December 21, 2010.

Intersegment revenues

•

Intersegment revenues increased $405.1 million, or 18.5%, from the 2010 quarter to $2.6 billion for the 2011 quarter and increased $1.0 billion, or 15.8%, from the 2010 period to $7.7 billion for the 2011 period. The increases primarily were due to growth in our pharmacy solutions business as it serves our growing membership, particularly Medicare stand-alone PDP.

Operating costs

•

The Health and Well-Being Services segment operating cost ratio of 96.3% for the 2011 quarter increased 10 basis points from the 2010 quarter. The CAC medical centers adjustment discussed above reduced the operating cost ratio 100 basis points in the 2010 quarter. The operating cost ratio for the 2011 period was 96.1%, decreasing 100 basis points from the 2010 period. Excluding the impact of the CAC medical centers adjustment, the decreases in our quarterly and year-to-date comparisons primarily reflect scale efficiencies associated with growth in our pharmacy solutions business together with the addition of our acquired Concentra operations which carry a lower operating cost ratio than other lines of business in this segment.

Other Businesses

Pretax income for our Other Businesses of $27.7 million for the 2011 quarter compares to $22.0 million for the 2010 quarter. Pretax income for our Other Businesses for the 2011 period of $82.3 million decreased $26.1 million from the 2010 period primarily due to a decrease in pretax income associated with our contract with CMS to administer the Limited Income Newly Eligible Transition (LI-NET) program.

Liquidity

Our primary sources of cash include receipts of premiums, service revenues, and investment and other income, as well as proceeds from the sale or maturity of our investment securities and borrowings. Our primary uses of cash include disbursements for claims payments, operating costs, interest on borrowings, taxes, purchases of investment securities, acquisitions, capital expenditures, repayments on borrowings, dividends, and share repurchases. Because premiums generally are collected in advance of claim payments by a period of up to several months, our business normally should produce positive cash flows during periods of increasing premiums and enrollment. Conversely, cash flows would be negatively impacted during periods of decreasing premiums and enrollment. From period to period, our cash flows may also be affected by the timing of working capital items. The use of operating cash flows may be limited by regulatory requirements which require, among other items, that our regulated subsidiaries maintain minimum levels of capital.

For additional information on our liquidity risk, please refer to the section entitled “Risk Factors” in this report and in our 2010 Form 10-K.

Cash and cash equivalents increased to $4,019.4 million at September 30, 2011 from $1,673.1 million at December 31, 2010. The change in cash and cash equivalents for the nine months ended September 30, 2011 and 2010 is summarized as follows:


	2011			2010
	(in thousands)
Net cash provided by operating activities	$	3,875,980		$	2,289,171
Net cash used in investing activities		(1,143,197	)		(865,070	)
Net cash used in financing activities		(386,515	)		(114,837	)

Increase in cash and cash equivalents	$	2,346,268		$	1,309,264

Cash Flow from Operating Activities

Our operating cash flows for the 2011 period were significantly impacted by the early receipt of the Medicare premium remittance for October 2011 of $1,795.6 million in September 2011 because the payment date of October 1, 2011 fell on a weekend. Generally, when the first day of a month falls on a weekend or holiday, with the exception of January 1 (New Year’s Day), we receive this payment at the end of the previous month. Therefore, the 2011 period included ten monthly Medicare payments compared to only nine monthly Medicare payments during the 2010 period. This also resulted in an increase to unearned revenues in our condensed consolidated balance sheet at September 30, 2011.

Excluding the impact from the timing of the Medicare premium receipt, the decrease in operating cash flows from the 2010 period to the 2011 period primarily results from the timing of other working capital items, partially offset by an increase in earnings.

Comparisons of our operating cash flows are impacted by changes in our working capital. The most significant drivers of changes in our working capital are typically the timing of receipts for premiums and payments of benefit expenses. We illustrate these changes with the following summaries of receivables and benefits payable.

The detail of total net receivables was as follows at September 30, 2011 and December 31, 2010:


	September 30,			December 31,			2011 Period			2010 Period
	2011			2010			Change			Change
	(in thousands)
Military services:
Base receivables	$	531,894		$	424,786		$	107,108		$	4,385
Change orders		497			2,052			(1,555	)		(248	)

Military services subtotal		532,391			426,838			105,553			4,137
Medicare		183,879			216,080			(32,201	)		(66,721	)
Commercial and other		405,062			367,570			37,492			50,337
Allowance for doubtful accounts		(85,015	)		(51,470	)		(33,545	)		(3,345	)

Total net receivables	$	1,036,317		$	959,018		$	77,299		$	(15,592	)

Military services base receivables consist of estimated claims owed from the federal government for health care services provided to beneficiaries and underwriting fees. The claim reimbursement component of military services base receivables is generally collected over a three to four month period. The timing of claim reimbursements resulted in the $107.1 million increase in base receivables from December 31, 2010 to September 30, 2011 and the $4.4 million increase in base receivables from December 31, 2009 to September 30, 2010.

Medicare receivables decreased $32.2 million from December 31, 2010 to September 30, 2011 and decreased $66.7 million from December 31, 2009 to September 30, 2010. Medicare receivables are impacted by the timing of accruals and related collections associated with the CMS risk-adjustment model.

Commercial and other receivables increased $37.5 million and the allowance for doubtful accounts increased $33.5 million from December 31, 2010 to September 30, 2011 primarily due to the Concentra acquisition. The $50.3 million increase in commercial and other receivables from December 31, 2009 to September 30, 2010 primarily resulted from the timing of reimbursements from the Puerto Rico Health Insurance Administration for our Medicaid business.

The detail of benefits payable was as follows at September 30, 2011 and December 31, 2010:


	September 30,		December 31,		2011 Period		2010 Period
	2011		2010		Change		Change
	(in thousands)
IBNR(1)	$	2,131,410	$	2,051,227	$	80,183	$	220,769
Military services benefits payable(2)		375,865		255,180		120,685		36,271
Reported claims in process(3)		331,045		136,803		194,242		226
Other benefits payable(4)		1,030,108		1,026,096		4,012		247,071

Total benefits payable	$	3,868,428	$	3,469,306	$	399,122	$	504,337

(1)

IBNR represents an estimate of benefits payable for claims incurred but not reported (IBNR) at the balance sheet date. The level of IBNR is primarily impacted by membership levels, medical claim trends and the receipt cycle time, which represents the length of time between when a claim is initially incurred and when the claim form is received (i.e. a shorter time span results in a lower IBNR).

(2)

Military services benefits payable primarily results from the timing of the cost of providing health care services to beneficiaries and the payment to the provider. A corresponding receivable for reimbursement by the federal government is included in the base receivable in the previous receivables table.

(3)

Reported claims in process represents the estimated valuation of processed claims that are in the post claim adjudication process, which consists of administrative functions such as audit and check batching and handling, as well as amounts owed to our pharmacy benefit administrator which fluctuate due to bi-weekly payments and the month-end cutoff.

(4)	Other benefits payable include amounts owed to providers under capitated and risk sharing arrangements.

The increase in benefits payable from December 31, 2010 to September 30, 2011 primarily was due to an increase in amounts due to our pharmacy benefit administrator which fluctuate due to month-end cutoff, an increase in Military services benefits payable, and an increase in IBNR as a result of Medicare Advantage membership

growth. The increase in benefits payable from December 31, 2009 to September 30, 2010 primarily was due to an increase in IBNR as well as an increase in amounts owed to providers under capitated and risk sharing arrangements, both primarily as a result of Medicare Advantage membership growth.

In addition to the timing of receipts for premiums and ASO fees and payments of benefit expenses, other working capital items impacting operating cash flows primarily resulted from the timing of payments for the Medicare Part D risk corridor provisions of our contracts with CMS. Payment under the risk corridor provisions is made in the fourth quarter of each year.

Cash Flow from Investing Activities

We reinvested a portion of our operating cash flows in investment securities, primarily fixed income securities, totaling $957.8 million in the 2011 period and $790.8 million in the 2010 period. Our ongoing capital expenditures primarily relate to our information technology initiatives and administrative facilities necessary for activities such as claims processing, billing and collections, wellness solutions, care coordination, regulatory compliance and customer service as well as patient services in our Concentra medical centers. Total capital expenditures, excluding acquisitions, were $215.9 million in the 2011 period compared to $152.4 million in the 2010 period. Excluding acquisitions, we expect total capital expenditures in 2011 of approximately $305 million versus $222 million for the full year 2010, primarily due to increased capital expenditures associated with growth in our pharmacy and primary care services businesses in our Health and Well-Being Services segment.

Cash Flow from Financing Activities

Receipts from CMS associated with Medicare Part D claim subsidies for which we do not assume risk were $225.4 million higher than claims payments during the 2011 period and $202.2 million higher than claim payments during the 2010 period.

During the 2011 period, we repurchased 6.7 million shares for $491.5 million under the stock repurchase plans authorized by the Board of Directors in December 2009 and April 2011. During the 2010 period, we repurchased 1.99 million shares for $100.0 million under the stock repurchase plan authorized by the Board of Directors in December 2009. During the 2011 period, we also acquired 0.8 million common shares in connection with employee stock plans for an aggregate cost of $48.7 million compared to 0.2 million shares for an aggregate cost of $8.2 million in the 2010 period.

During the 2011 period, we paid dividends to stockholders of $41.5 million as discussed further below. No dividends were paid during 2010.

The remainder of the cash used in or provided by financing activities in the 2011 and 2010 periods primarily resulted from the change in the book overdraft and proceeds from stock option exercises.

Future Sources and Uses of Liquidity

Dividends

The following table provides details of our dividend payments in 2011:


Record Date	Payment Date	Amount per Share		Total Amount
				(in millions)
6/30/2011	7/28/2011	$	0.25	$	41.5
9/30/2011	10/28/2011	$	0.25	$	40.7

In addition, in October 2011, our Board of Directors declared a cash dividend to stockholders of $0.25 per share payable on January 31, 2012 to stockholders of record on December 30, 2011.

Stock Repurchase Authorization

In April 2011, the Board of Directors replaced its previously approved share repurchase authorization of up to $250 million with a new authorization for repurchases of up to $1 billion of our common shares exclusive of shares repurchased in connection with employee stock plans. The new authorization will expire June 30, 2013. Under this share repurchase authorization, shares may be purchased from time to time at prevailing prices in the open market, by block purchases, or in privately-negotiated transactions, subject to certain regulatory restrictions on volume, pricing, and timing. As of October 31, 2011, the remaining authorized amount under the new authorization totaled $561.3 million.

Senior Notes

We previously issued $500 million of 6.45% senior notes due June 1, 2016, $500 million of 7.20% senior notes due June 15, 2018, $300 million of 6.30% senior notes due August 1, 2018, and $250 million of 8.15% senior notes due June 15, 2038. The 7.20% and 8.15% senior notes are subject to an interest rate adjustment if the debt ratings assigned to the notes are downgraded (or subsequently upgraded) and contain a change of control provision that may require us to purchase the notes under certain circumstances. All four series of our senior notes, which are unsecured, may be redeemed at our option at any time at 100% of the principal amount plus accrued interest and a specified make-whole amount.

Credit Agreement

Our 3-year $1.0 billion unsecured revolving agreement expires December 2013. Under the credit agreement, at our option, we can borrow on either a competitive advance basis or a revolving credit basis. The revolving credit portion bears interest at either LIBOR or the base rate plus a spread. The spread, currently 170 basis points, varies depending on our credit ratings ranging from 150 to 262.5 basis points. We also pay an annual facility fee regardless of utilization. This facility fee, currently 30 basis points, may fluctuate between 25 and 62.5 basis points, depending upon our credit ratings. The competitive advance portion of any borrowings will bear interest at market rates prevailing at the time of borrowing on either a fixed rate or a floating rate based on LIBOR, at our option.

The terms of the credit agreement include standard provisions related to conditions of borrowing, including a customary material adverse event clause which could limit our ability to borrow additional funds. In addition, the credit agreement contains customary restrictive and financial covenants as well as customary events of default, including financial covenants regarding the maintenance of a minimum level of net worth of $5,868.0 million at September 30, 2011 and a maximum leverage ratio of 3.0:1. We are in compliance with the financial covenants, with actual net worth of $7,858.0 million and a leverage ratio of 0.6:1, as measured in accordance with the credit agreement as of September 30, 2011. In addition, the credit agreement includes an uncommitted $250 million incremental loan facility.

At September 30, 2011, we had no borrowings outstanding under the credit agreement. We have outstanding letters of credit of $11.6 million secured under the credit agreement. No amounts have ever been drawn on these letters of credit. Accordingly, as of September 30, 2011, we had $988.4 million of remaining borrowing capacity under the credit agreement, none of which would be restricted by our financial covenant compliance requirement. We have other customary, arms-length relationships, including financial advisory and banking, with some parties to the credit agreement.

Other Long-Term Borrowings

Other long-term borrowings of $36.6 million at September 30, 2011 represent junior subordinated debt of $36.1 million and financing for the renovation of a building of $0.5 million. The junior subordinated debt, which is due in 2037, may be called by us without penalty in 2012 and bears a fixed annual interest rate of 8.02% payable quarterly until 2012, and then payable at a floating rate based on LIBOR plus 310 basis points. The debt associated with the building renovation bears interest at 2.00%, is collateralized by the building, and is payable in various installments through 2014.

Liquidity Requirements

We believe our cash balances, investment securities, operating cash flows, and funds available under our credit agreement or from other public or private financing sources, taken together, provide adequate resources to fund ongoing operating and regulatory requirements, future expansion opportunities, and capital expenditures for at least the next twelve months, as well as to refinance or repay debt and repurchase shares.

Adverse changes in our credit rating may increase the rate of interest we pay and may impact the amount of credit available to us in the future. Our investment-grade credit rating at September 30, 2011 was BBB according to Standard & Poor’s Rating Services, or S&P, and Baa3 according to Moody’s Investors Services, Inc., or Moody’s. A downgrade by S&P to BB+ or by Moody’s to Ba1 triggers an interest rate increase of 25 basis points with respect to $750 million of our senior notes. Successive one notch downgrades increase the interest rate an additional 25 basis points, or annual interest expense by $1.9 million, up to a maximum 100 basis points, or annual interest expense by $7.5 million.

In addition, we operate as a holding company in a highly regulated industry. The parent company is dependent upon dividends and administrative expense reimbursements from our subsidiaries, most of which are subject to regulatory restrictions. Dividends to our parent company from our operating subsidiaries were approximately $1.1 billion in the 2011 period compared to approximately $747 million in 2010. We continue to maintain significant levels of aggregate excess statutory capital and surplus in our state-regulated operating subsidiaries.

Regulatory Requirements

Certain of our subsidiaries operate in states that regulate the payment of dividends, loans, or other cash transfers to Humana Inc., our parent company, and require minimum levels of equity as well as limit investments to approved securities. The amount of dividends that may be paid to Humana Inc. by these subsidiaries, without prior approval by state regulatory authorities, is limited based on the entity’s level of statutory income and statutory capital and surplus. In most states, prior notification is provided before paying a dividend even if approval is not required.

Although minimum required levels of equity are largely based on premium volume, product mix, and the quality of assets held, minimum requirements can vary significantly at the state level. Based on the most recently filed statutory financial statements as of June 30, 2011, our state regulated subsidiaries had aggregate statutory capital and surplus of approximately $4.1 billion, which exceeded aggregate minimum regulatory requirements.

Item 3. Quantitative and Qualitative Disclosure about Market Risk

Our earnings and financial position are exposed to financial market risk, including those resulting from changes in interest rates.

Interest rate risk also represents a market risk factor affecting our consolidated financial position due to our significant investment portfolio, consisting primarily of fixed maturity securities of investment-grade quality with a weighted average S&P credit rating of AA at September 30, 2011. Our net unrealized gain position increased $251.1 million from a net unrealized gain position of $196.5 million at December 31, 2010 to a net unrealized gain position of $447.6 million at September 30, 2011. At September 30, 2011, we had gross unrealized losses of $35.8 million on our investment portfolio primarily due to an increase in market interest rates and tighter liquidity conditions in the current markets than when the securities were purchased, and as such, there were no material other-than-temporary impairments during the three and nine months ended September 30, 2011. While we believe that these impairments are temporary and we currently do not have the intent to sell such securities, given the current market conditions and the significant judgments involved, there is a continuing risk that future declines in fair value may occur and material realized losses from sales or other-than-temporary impairments may be recorded in future periods.

Duration is the time-weighted average of the present value of the bond portfolio’s cash flow. Duration is indicative of the relationship between changes in fair value and changes in interest rates, providing a general indication of the sensitivity of the fair values of our fixed maturity securities to changes in interest rates. However, actual fair values may differ significantly from estimates based on duration. The average duration of our investment portfolio, including cash and cash equivalents, was approximately 3.1 years as of September 30, 2011. Based on the duration including cash equivalents, a 1% increase in interest rates would generally decrease the fair value of our securities by approximately $418 million.

Item 4. Controls and Procedures

Under the supervision and with the participation of our Chief Executive Officer, or CEO, our Chief Financial Officer, or CFO, and our Principal Accounting Officer, we carried out an evaluation of the effectiveness of the design and operation of our disclosure controls and procedures for the quarter ended September 30, 2011.

Based on our evaluation, our CEO, CFO, and Principal Accounting Officer concluded that our disclosure controls and procedures are effective to provide reasonable assurance that information the Company is required to disclose in its reports under the Securities Exchange Act of 1934 is recorded, processed, summarized and reported within the time periods specified in SEC rules and forms, including, without limitation, ensuring that such information is accumulated and communicated to the Company’s management, including its principal executive and principal financial officers, or persons performing similar functions, as appropriate to allow timely decisions regarding required disclosure.

There have been no changes in the Company’s internal control over financial reporting during the quarter ended September 30, 2011 that have materially affected, or are reasonably likely to materially affect, the Company’s internal control over financial reporting.

Part II. Other Information

Item 1. Legal Proceedings

For a description of the legal proceedings pending against us, see “Legal Proceedings and Certain Regulatory Matters” in Note 12 to the condensed consolidated financial statements beginning on page 19 of this Form 10-Q.

Item 1A. Risk Factors

Except as set forth below, there have been no changes to the risk factors included in our 2010 Form 10-K, as modified by the changes to those risk factors included in other reports we filed with the SEC subsequent to February 17, 2011:

•

On February 25, 2011, the Department of Defense TRICARE Management Activity, or TMA, awarded the TRICARE South Region contract to us. On March 7, 2011, the competing bidder filed a protest of the award with the Government Accountability Office, or GAO. Also on March 7, 2011, as provided in the Federal Acquisition Regulations, TMA issued a stop work order to us in connection with the award. On June 14, 2011, the GAO upheld the award of the contract to us and TMA subsequently lifted the stop work order. On June 21, 2011, the competing bidder filed a complaint in the United States Court of Federal Claims objecting to the award of the contract to us. On October 14, 2011, the Court upheld the award of the contract to us, and the competing bidder has until December 13, 2011 to appeal it in the Court of Appeals for the Federal Circuit. As a result of the award of the TRICARE South Region contract to us, we no longer expect a goodwill impairment to occur during the second half of 2011. Ultimate disposition of the contract award is, however, subject to the resolution of any additional actions the unsuccessful bidder may take.

•

As a government contractor, we are exposed to risks that may materially adversely affect our business or our willingness or ability to participate in government health care programs.

A significant portion of our revenues relates to federal and state government health care coverage programs, including the Medicare, Military, and Medicaid programs. These programs accounted for approximately 77% of our total premiums and services revenue for the nine months ended September 30, 2011. These programs involve various risks, as described in our 2010 Form 10-K and supplemented as follows:

•

The Budget Control Act of 2011, enacted on August 2, 2011, increased the United States debt ceiling in connection with deficit reductions over the next ten years. The Budget Control Act of 2011 also establishes a twelve-member joint committee of Congress known as the Joint Select Committee on Deficit Reduction to propose legislation to reduce the United States federal deficit by $1.5 trillion for fiscal years 2012-2021. Reductions in Medicare and Medicaid spending could be included as part of these deficit reduction measures. Moreover, if such legislation is not enacted by December 23, 2011, approximately $1.2 trillion in domestic and defense spending reductions will automatically begin January 1, 2013, split evenly between domestic and defense spending. Payments to Medicare providers would be subject to these automatic spending reductions, subject to a 2% cap. At this time it is unclear how this automatic reduction may be applied to various Medicare healthcare programs. We expect that if such reductions were to occur, there would be a corresponding substantial reduction in our obligations to providers, however there can be no assurances that this would completely offset any reductions to the Medicare healthcare programs applied by the Budget Control Act of 2011.

This list of important factors is not intended to be exhaustive, and should be read in conjunction with the more detailed description of these risks that may be found in our reports filed with the SEC from time to time, including our annual report on Form 10-K, quarterly reports on Form 10-Q, and current reports on Form 8-K.

The new authorization will expire June 30, 2013. Under this share repurchase authorization, shares may be purchased from time to time at prevailing prices in the open market, by block purchases, or in privately-negotiated transactions, subject to certain regulatory restrictions on volume, pricing, and timing. As of October 31, 2011, the remaining authorized amount under the new authorization totaled $561.3 million.
