| Basis Of Presentation And Significant Accounting Policies | 2. Basis of Presentation and Significant Accounting Policies
Basis of Presentation: The accompanying consolidated financial statements include the accounts of WellPoint and its subsidiaries and have been prepared in conformity with U.S. generally accepted accounting principles, or GAAP. All significant intercompany accounts and transactions have been eliminated in consolidation. Certain of our subsidiaries operate outside of the United States and have functional currencies other than the U.S. dollar, or USD. We translate the assets and liabilities of those subsidiaries to USD using the exchange rate in effect at the end of the period. We translate the revenues and expenses of those subsidiaries to USD using the average exchange rates in effect during the period. The net effect of these translation adjustments is included in “Foreign currency translation adjustments” in our consolidated statements of shareholders' equity.
Use of Estimates: The preparation of consolidated financial statements in conformity with GAAP requires us to make estimates and assumptions that affect the amounts reported in our consolidated financial statements and accompanying notes. Actual results could differ from those estimates. Cash Equivalents: All highly liquid investments with maturities of three months or less when purchased are classified as cash equivalents.
Investments: Certain Financial Accounting Standards Board, or FASB, other-than-temporary impairment, or FASB OTTI, guidance applies to fixed maturity securities and provides guidance on the recognition and presentation of other-than-temporary impairments. In addition, this FASB OTTI guidance requires disclosures related to other-than-temporary impairments. If a fixed maturity security is in an unrealized loss position and we have the intent to sell the fixed maturity security, or it is more likely than not that we will have to sell the fixed maturity security before recovery of its amortized cost basis, the decline in value is deemed to be other-than-temporary and is recorded to other-than-temporary impairment losses recognized in income in our consolidated income statements. For impaired fixed maturity securities that we do not intend to sell or it is more likely than not that we will not have to sell such securities, but we expect that we will not fully recover the amortized cost basis, the credit component of the other-than-temporary impairment is recognized in other-than-temporary impairment losses recognized in income in our consolidated income statements and the non-credit component of the other-than-temporary impairment is recognized in other comprehensive income. Furthermore, unrealized losses entirely caused by non-credit related factors related to fixed maturity securities for which we expect to fully recover the amortized cost basis continue to be recognized in accumulated other comprehensive income, or AOCI.
The credit component of an other-than-temporary impairment is determined by comparing the net present value of projected future cash flows with the amortized cost basis of the fixed maturity security. The net present value is calculated by discounting our best estimate of projected future cash flows at the effective interest rate implicit in the fixed maturity security at the date of acquisition. For mortgage-backed and asset-backed securities, cash flow estimates are based on assumptions regarding the underlying collateral including prepayment speeds, vintage, type of underlying asset, geographic concentrations, default rates, recoveries and changes in value. For all other debt securities, cash flow estimates are driven by assumptions regarding probability of default, including changes in credit ratings, and estimates regarding timing and amount of recoveries associated with a default.
The unrealized gains or losses on our current and long-term equity securities classified as available-for-sale are included in accumulated other comprehensive income as a separate component of shareholders' equity, unless the decline in value is deemed to be other-than-temporary and we do not have the intent and ability to hold such equity securities until their full cost can be recovered, in which case such equity securities are written down to fair value and the loss is charged to other-than-temporary impairment losses recognized in income. We maintain various rabbi trusts to account for the assets and liabilities under certain deferred compensation plans. Under these plans, the participants can defer certain types of compensation and elect to receive a return on the deferred amounts based on the changes in fair value of various investment options, primarily a variety of mutual funds. Rabbi trust assets are classified as trading, which are reported in other invested assets, current, in the consolidated balance sheets. We use the equity method of accounting for investments in companies in which our ownership interest enables us to influence the operating or financial decisions of the investee company. Our proportionate share of equity in net income of these unconsolidated affiliates is reported with net investment income.
For asset-backed securities included in fixed maturity securities, we recognize income using an effective yield based on anticipated prepayments and the estimated economic life of the securities. When estimates of prepayments change, the effective yield is recalculated to reflect actual payments to date and anticipated future payments. The net investment in the securities is adjusted to the amount that would have existed had the new effective yield been applied since the acquisition of the securities. Such adjustments are reported with net investment income.
Investment income is recorded when earned. All securities sold resulting in investment gains and losses are recorded on the trade date. Realized gains and losses are determined on the basis of the cost or amortized cost of the specific securities sold.
We participate in securities lending programs whereby marketable securities in our investment portfolio are transferred to independent brokers or dealers based on, among other things, their creditworthiness in exchange for cash collateral initially equal to at least 102% of the value of the securities on loan and is thereafter maintained at a minimum of 100% of the market value of the securities loaned (calculated as the ratio of initial market value of cash collateral to current market value of the securities on loan). Accordingly, the market value of the securities on loan to each borrower is monitored daily and the borrower is required to deliver additional cash collateral if the market value of the securities on loan exceeds the initial market value of cash collateral delivered. The fair value of the collateral received at the time of the transaction amounted to $564.7 and $872.5 at December 31, 2012 and 2011, respectively. The value of the cash collateral delivered represented 102% of the market value of the securities on loan at December 31, 2012 and 2011. Under the FASB guidance related to accounting for transfers and servicing of financial assets and extinguishments of liabilities, we recognize the cash collateral as an asset, which is reported as “securities lending collateral” on our consolidated balance sheets and we record a corresponding liability for the obligation to return the cash collateral to the borrower, which is reported as “securities lending payable.” The securities on loan are reported in the applicable investment category on the consolidated balance sheets. Unrealized gains or losses on securities lending collateral are included in accumulated other comprehensive income as a separate component of shareholders' equity.
Premium and Self-Funded Receivables: Premium and self-funded receivables include the uncollected amounts from fully-insured and self-funded groups, and are reported net of an allowance for doubtful accounts of $197.1 and $183.7 at December 31, 2012 and 2011, respectively. The allowance for doubtful accounts is based on historical collection trends and our judgment regarding the ability to collect specific accounts.
Other Receivables: Other receivables include pharmacy rebates, provider advances, claims recoveries, reinsurance, government programs, proceeds due from brokers on investment trades and other miscellaneous amounts due to us. These receivables are reported net of an allowance for uncollectible amounts of $79.0 and $149.1 at December 31, 2012 and 2011, respectively, which is based on historical collection trends and our judgment regarding the ability to collect specific amounts.
Income Taxes: We file a consolidated income tax return. Deferred income tax assets and liabilities are recognized for temporary differences between the financial statement and tax return bases of assets and liabilities based on enacted tax rates and laws. The deferred tax benefits of the deferred tax assets are recognized to the extent realization of such benefits is more likely than not. Deferred income tax expense or benefit generally represents the net change in deferred income tax assets and liabilities during the year, excluding the impact from amounts initially recorded for business combinations, if any. Current income tax expense represents the tax consequences of revenues and expenses currently taxable or deductible on various income tax returns for the year reported.
We account for income tax contingencies in accordance with FASB guidance that contains a model to address uncertainty in tax positions and clarifies the accounting for income taxes by prescribing a minimum recognition threshold, which all income tax positions must achieve before being recognized in the financial statements.
Property and Equipment: Property and equipment is recorded at cost, net of accumulated depreciation. Depreciation is computed principally by the straight-line method over estimated useful lives ranging from 15 to 39 years for buildings and improvements, three to seven years for furniture and equipment, and three to five years for computer software. Leasehold improvements are depreciated over the term of the related lease. Certain costs related to the development or purchase of internal-use software are capitalized and amortized.
Goodwill and Other Intangible Assets: FASB guidance requires business combinations to be accounted for using the acquisition method of accounting and it also specifies the types of acquired intangible assets that are required to be recognized and reported separately from goodwill. Goodwill represents the excess of cost of acquisition over the fair value of net assets acquired. Other intangible assets represent the values assigned to subscriber bases, provider and hospital networks, Blue Cross and Blue Shield and other trademarks, licenses, non-compete and other agreements. Goodwill and other intangible assets are allocated to reportable segments based on the relative fair value of the components of the businesses acquired.
Goodwill and other intangible assets with indefinite lives are not amortized but are tested for impairment at least annually. Furthermore, goodwill and other intangible assets are allocated to reporting units for purposes of the annual impairment test. Our impairment tests require us to make assumptions and judgments regarding the estimated fair value of our reporting units, including goodwill and other intangible assets with indefinite lives. In addition, certain other intangible assets with indefinite lives, such as trademarks, are also tested separately. Fair value is calculated using a blend of a projected income and market valuation approach. The projected income approach is developed using assumptions about future revenue, expenses and net income derived from our internal planning process. Our assumed discount rate is based on our industry's weighted-average cost of capital and reflects volatility associated with the cost of equity capital. Market valuations are based on observed multiples of certain measures including membership, revenue, EBITDA (earnings before interest, taxes, depreciation and amortization) and net income as well as market capitalization analyses of WellPoint and other comparable companies. Estimated fair values developed based on our assumptions and judgments might be significantly different if other reasonable assumptions and estimates were to be used. If estimated fair values are less than the carrying values of goodwill and other intangible assets with indefinite lives in future annual impairment tests, or if significant impairment indicators are noted relative to other intangible assets subject to amortization, we may be required to record impairment losses against future income.
Derivative Financial Instruments: We primarily invest in the following types of derivative financial instruments: interest rate swaps, forward contracts, call options, credit default swaps, embedded derivatives, warrants and swaptions. Derivatives embedded within non-derivative instruments (such as options embedded in convertible fixed maturity securities) are bifurcated from the host instrument when the embedded derivative is not clearly and closely related to the host instrument. Our use of derivatives is limited by statutes and regulations promulgated by the various regulatory bodies to which we are subject, and by our own derivative policy. Our derivative use is generally limited to hedging purposes and we generally do not use derivative instruments for speculative purposes.
We have exposure to economic losses due to interest rate risk arising from changes in the level or volatility of interest rates. We attempt to mitigate our exposure to interest rate risk through active portfolio management, including rebalancing our existing portfolios of assets and liabilities, as well as changing the characteristics of investments to be purchased or sold in the future. In addition, derivative financial instruments are used to modify the interest rate exposure of certain liabilities or forecasted transactions. These strategies include the use of interest rate swaps and forward contracts, which are used to lock-in interest rates or to hedge (on an economic basis) interest rate risks associated with variable rate debt. We have used these types of instruments as designated hedges against specific liabilities.
All investments in derivatives are recorded as assets or liabilities at fair value. If certain correlation, hedge effectiveness and risk reduction criteria are met, a derivative may be specifically designated as a hedge of exposure to changes in fair value or cash flow. The accounting for changes in the fair value of a derivative depends on the intended use of the derivative and the nature of any hedge designation thereon. Amounts excluded from the assessment of hedge effectiveness, if any, as well as the ineffective portion of the gain or loss, are reported in results of operations immediately. If the derivative is not designated as a hedge, the gain or loss resulting from the change in the fair value of the derivative is recognized in results of operations in the period of change.
From time to time, we may also purchase derivatives to hedge (on an economic basis) our exposure to foreign currency exchange fluctuations associated with the operations of certain of our subsidiaries. We generally use futures or forward contracts for these transactions. We generally do not designate these contracts as hedges and, accordingly, the changes in fair value of these derivatives are recognized in income immediately.
Credit exposure associated with non-performance by the counterparties to derivative instruments is generally limited to the uncollateralized fair value of the asset related to instruments recognized in the consolidated balance sheets. We attempt to mitigate the risk of non-performance by selecting counterparties with high credit ratings and monitoring their creditworthiness and by diversifying derivatives among multiple counterparties. At December 31, 2012, we believe there were no material concentrations of credit risk with any individual counterparty.
Certain of our derivative agreements contain credit support provisions that require us to post collateral if there are declines in the derivative fair value or our credit rating.
Retirement Benefits: We recognize the funded status of pension and other postretirement benefit plans on the consolidated balance sheets based on fiscal-year-end measurements of plan assets and benefit obligations. Prepaid pension benefits represent prepaid costs related to defined benefit pension plans and are reported with other noncurrent assets. Postretirement benefits represent outstanding obligations for retiree medical, life, vision and dental benefits. Liabilities for pension and other postretirement benefits are reported with current and noncurrent liabilities based on the amount by which the actuarial present value of benefits payable in the next twelve months included in the benefit obligation exceeds the fair value of plan assets.
Medical Claims Payable: Liabilities for medical claims payable include estimated provisions for incurred but not paid claims on an undiscounted basis, as well as estimated provisions for expenses related to the processing of claims. Incurred but not paid claims include (1) an estimate for claims that are incurred but not reported, as well as claims reported to us but not yet processed through our systems; and (2) claims reported to us and processed through our systems but not yet paid.
Liabilities for both claims incurred but not reported and reported but not yet processed through our systems are determined in aggregate by employing actuarial methods that are commonly used by health insurance actuaries and meet Actuarial Standards of Practice. Actuarial Standards of Practice require that the claim liabilities be appropriate under moderately adverse circumstances. We determine the amount of the liability for incurred but not paid claims by following a detailed actuarial process that entails using both historical claim payment patterns as well as emerging medical cost trends to project our best estimate of claim liabilities.
We regularly review and set assumptions regarding cost trends and utilization when initially establishing claim liabilities. We continually monitor and adjust the claims liability and benefit expense based on subsequent paid claims activity. If our assumptions regarding cost trends and utilization are significantly different than actual results, our income statement and financial position could be impacted in future periods.
Premium deficiencies are recognized when it is probable that expected claims and administrative expenses will exceed future premiums on existing medical insurance contracts without consideration of investment income. Determination of premium deficiencies for longer duration life and disability contracts includes consideration of investment income. For purposes of premium deficiencies, contracts are deemed to be either short or long duration and are grouped in a manner consistent with our method of acquiring, servicing and measuring the profitability of such contracts. Once established, premium deficiencies are released commensurate with actual claims experience over the remaining life of the contract. No premium deficiencies were established at December 31, 2012 or 2011.
Reserves for Future Policy Benefits: Reserves for future policy benefits include liabilities for life and long-term disability insurance policy benefits based upon interest, mortality and morbidity assumptions from published actuarial tables, modified based upon our experience. Future policy benefits also include liabilities for insurance policies for which some of the premiums received in earlier years are intended to pay anticipated benefits to be incurred in future years. Future policy benefits are continually monitored and reviewed, and when reserves are adjusted, differences are reflected in benefit expense. The current portion of reserves for future policy benefits relates to the portion of such reserves that we expect to pay within one year. We believe that our liabilities for future policy benefits, along with future premiums received are adequate to satisfy our ultimate benefit liability; however, these estimates are inherently subject to a number of variable circumstances. Consequently, the actual results could differ materially from the amounts recorded in our consolidated financial statements.
Other Policyholder Liabilities: Other policyholder liabilities include rate stabilization reserves associated with retrospectively rated insurance contracts and certain case-specific reserves as well as liabilities for minimum medical loss ratio, or MLR, rebates. Rate stabilization reserves represent accumulated premiums that exceed what customers owe us based on actual claim experience. The timing of payment of these retrospectively rated refunds is based on the contractual terms with the customers and can vary from period to period based on the specific contractual requirements.
Effective beginning in 2011, we are required to meet certain minimum MLR thresholds prescribed by the Patient Protection and Affordable Care Act and related Health Care and Education Reconciliation Act of 2010, or collectively, Health Care Reform. If we do not meet or exceed the minimum MLR thresholds specified by Health Care Reform, we are required to pay rebates to certain customers. Minimum MLR rebates are calculated by applicable line of business (large group, small group and individual) and legal entity in accordance with regulations issued by the Department of Health and Human Services, or HHS. Such calculations are made using estimated calendar year medical loss expense and premiums, as defined by HHS.
We follow HHS guidelines for determining the types of expenses that may be included in our minimum MLR rebate calculations, which may differ from benefit expense and premiums as reported in our consolidated financial statements prepared in conformity with GAAP. Certain amounts reported as expense in our GAAP basis consolidated financial statements may be reported as a reduction of premiums in accordance with HHS regulations. For example, certain federal and state income taxes and assessments recorded as income tax expense or general and administrative expense, as appropriate, in our consolidated GAAP financial statements are allowed to be included as a reduction of premium revenue in HHS' calculation of minimum MLR. In addition, profit amounts included in our payments to third party administrative service providers are recorded as benefit expense in our consolidated GAAP financial statements while HHS does not allow for the inclusion of these expenses within the medical loss expense for purposes of calculating minimum MLR.
Revenue Recognition: Premiums for fully-insured contracts are recognized as revenue over the period insurance coverage is provided, net of amounts recognized for minimum MLR rebates, if applicable. Minimum MLR rebates are calculated in accordance with regulations issued by HHS. Premiums applicable to the unexpired contractual coverage periods are reflected in the accompanying consolidated balance sheets as unearned income. Premiums include revenue from retrospectively rated contracts where revenue is based on the estimated ultimate loss experience of the contract. Premium revenue includes an adjustment for retrospectively rated refunds based on an estimate of incurred claims. Premium rates for certain lines of business are subject to approval by the Department of Insurance of each respective state.
Administrative fees include revenue from certain group contracts that provide for the group to be at risk for all, or with supplemental insurance arrangements, a portion of their claims experience. We charge these self-funded groups an administrative fee, which is based on the number of members in a group or the group's claim experience. In addition, administrative fees include amounts received for the administration of Medicare or certain other government programs. Under our self-funded arrangements, revenue is recognized as administrative services are performed. All benefit payments under these programs are excluded from benefit expense.
Other revenue primarily includes ocular product sales by 1-800 CONTACTS, which are recognized as revenue when the products are shipped. For additional information about 1-800 CONTACTS, see Note 3, “Business Combinations.”
Share-Based Compensation: Our current compensation philosophy provides for share-based compensation, including stock options and restricted stock awards. Stock options are granted for a fixed number of shares with an exercise price at least equal to the fair value of the shares at the date of the grant. Restricted stock awards are issued at the fair value of the stock on the grant date. During 2010, we also offered an employee stock purchase plan. The employee stock purchase plan, which was suspended effective January 1, 2011, allowed for a purchase price per share which was 85% of the fair value of a share of common stock on the last trading day of the plan quarter. All share-based payments to employees, including grants of employee stock options and discounts associated with employee stock purchases, are recognized as compensation expense in the income statement based on their fair values. Additionally, excess tax benefits, which result from actual tax benefits exceeding deferred tax benefits previously recognized based on grant date fair value, are recognized as additional paid-in-capital and are reclassified from operating cash flows to financing cash flows in the consolidated statements of cash flows. Our share-based employee compensation plans and assumptions are described in Note 15, “Capital Stock.”
Advertising costs: We use print, broadcast and other advertising to promote our products and to develop our corporate image. The cost of advertising for product promotion is expensed as incurred while advertising associated with corporate image is expensed when first aired. Total advertising expense was $299.2, $287.8 and $226.1 for the years ended December 31, 2012, 2011 and 2010, respectively.
Earnings per Share: Earnings per share amounts, on a basic and diluted basis, have been calculated based upon the weighted-average common shares outstanding for the period.
Basic earnings per share excludes dilution and is computed by dividing income available to common shareholders by the weighted-average number of common shares outstanding for the period. Diluted earnings per share includes the dilutive effect of stock options and restricted stock, using the treasury stock method. The treasury stock method assumes exercise of stock options and vesting of restricted stock, with the assumed proceeds used to purchase common stock at the average market price for the period. The difference between the number of shares assumed issued and number of shares assumed purchased represents the dilutive shares.
New Accounting Pronouncements: In June 2011, the FASB issued Accounting Standards Update, or ASU, 2011-05, Comprehensive Income (Topic 220): Presentation of Comprehensive Income, or ASU 2011-05. ASU 2011-05 supersedes certain portions of Accounting Standards Codification Topic 220, Comprehensive Income, or ASC 220, and requires increased prominence of the presentation of other comprehensive income in financial statements. ASU 2011-05 requires entities to present net income and the components of other comprehensive income in either a single continuous financial statement or in two separate but consecutive financial statements. ASU 2011-05 eliminates the option in ASC 220 to present the components of other comprehensive income in the statement of changes in equity. Most of the presentation requirements of ASU 2011-05 became effective for us on a retrospective basis beginning January 1, 2012. However, certain presentation requirements of ASU 2011-05 were deferred by the FASB's December 2011 issuance of ASU 2011-12, Deferral of the Effective Date for Amendments to the Presentation of Reclassifications of Items Out of Accumulated Other Comprehensive Income in Accounting Standards Update No. 2011-05. We elected to present the components of comprehensive income in two separate but consecutive financial statements, which is illustrated in the “Consolidated Statements of Income” and the “Consolidated Statements of Comprehensive Income.” In May 2011, the FASB issued ASU 2011-04, Fair Value Measurement (Topic 820): Amendments to Achieve Common Fair Value Measurement and Disclosure Requirements in U.S. GAAP and IFRSs, or ASU 2011-04. ASU 2011-04 amends ASC Topic 820, Fair Value Measurement, to provide guidance on how fair value measurement should be applied where existing GAAP already requires or permits fair value measurements. In addition, ASU 2011-04 requires expanded disclosures regarding fair value measurements. The adoption of ASU 2011-04 on January 1, 2012 did not have a material impact on our consolidated financial position, results of operations or cash flows. However, we have added certain disclosures related to fair value measurements in Note 7, “Fair Value.”
There were no other new accounting pronouncements that were issued or became effective during the year ended December 31, 2012 that had, or are expected to have, a material impact on our financial position, results of operations or financial statement disclosures.
Reclassifications: As discussed above within the “Other Policyholder Liabilities” section of this Note 2, “Basis of Presentation and Significant Accounting Policies,” Health Care Reform requires that certain lines of business meet specified minimum MLR thresholds. If those thresholds are not met or exceeded, we are required to pay minimum MLR rebates. For purposes of determining MLR rebates, HHS has defined the types of costs that should be included in the minimum MLR rebate calculation. HHS' definition of costs varied from our prior benefit expense classification under GAAP. Where appropriate, we adopted HHS' classification of costs effective January 1, 2011 to further align our GAAP basis benefit expense to that used in the calculation for determining MLR rebates under HHS guidance. However, certain components of the MLR computation as defined by HHS cannot be classified consistently under GAAP. Accordingly, benefit expense ratios shown in our GAAP basis presentation are different than the MLRs used to calculate rebates under HHS guidance. Prior period amounts were not reclassified due to immateriality.
Certain other prior year amounts have been reclassified to conform to the current year presentation. |

Acquisition of Amerigroup
On December 24, 2012, we completed our acquisition of Amerigroup, one of the nation's leading managed care companies focused on meeting the health care needs of financially vulnerable Americans. This acquisition furthers our goal of creating better health care quality at more affordable prices for our customers. Amerigroup also advances our capabilities in effectively and efficiently serving the growing Medicaid population, including the expanding dual eligibles, seniors, persons with disabilities and long-term services and support markets. We paid $92.00 per share in cash to acquire all of the outstanding shares of Amerigroup for total cash consideration of $4,755.8. In addition, 0.5 shares of Amerigroup restricted stock converted to 0.7 shares of WellPoint restricted stock, valued at $17.1, and 0.1 shares underlying Amerigroup stock options converted to 0.2 shares underlying WellPoint stock options, valued at $2.6. We also incurred $24.0 of transaction costs, which were recorded to general and administrative expense during the year ended December 31, 2012. In accordance with FASB accounting guidance for business combinations, the consideration transferred was allocated to the fair value of Amerigroup's assets acquired and liabilities assumed, including identifiable intangible assets. The excess of the consideration transferred over the preliminary fair value of net assets acquired resulted in preliminary non-tax-deductible goodwill of $3,033.1 at December 31, 2012, all of which was allocated to our Consumer segment. Preliminary goodwill recognized from the acquisition of Amerigroup primarily relates to the future economic benefits arising from expected synergies and is consistent with our stated intentions to strengthen our position and expand operations in the government sector to serve Medicaid and Medicare enrollees. Any subsequent adjustments made to the assets acquired or liabilities assumed during the measurement period will be recorded as an adjustment to goodwill. The preliminary fair values of Amerigroup assets acquired and liabilities assumed as of the date of acquisition are summarized as follows:
Of the $955.0 of total other intangible assets acquired, $65.0 represents finite-lived customer relationships with an amortization period of three years, $30.0 represents provider and hospital networks with an amortization period of 20 years and $860.0 represents indefinite-lived state Medicaid contracts and trade names. The results of operations of Amerigroup for the period following December 24, 2012 are included in our consolidated financial statements within our Consumer segment and represented $219.0 and $6.1 of the Company's operating revenue and net loss, respectively, for the year ended December 31, 2012. The pro-forma effects of this acquisition for prior periods were not considered material to our consolidated results of operations.
Acquisition of 1-800 CONTACTS
On June 20, 2012, we completed our acquisition of 1-800 CONTACTS, the largest direct-to-consumer retailer of contact lenses in the United States, whose model is built on providing a superior customer experience and a wide selection of ocular products at affordable prices. The acquisition strategically aligns with our efforts to capitalize on new opportunities for growth to diversify our revenue stream into complementary and higher-margin specialty businesses. In accordance with FASB accounting guidance for business combinations, the consideration transferred was allocated to the fair value of 1-800 CONTACTS' assets acquired and liabilities assumed, including identifiable intangible assets. The excess of the consideration transferred over the fair value of net assets acquired resulted in preliminary non-tax-deductible goodwill of $620.7 at December 31, 2012, all of which was allocated to our Commercial segment. Preliminary goodwill recognized from the acquisition of 1-800 CONTACTS primarily relates to the expected future growth of 1-800 CONTACTS' business and further expansion of product offerings, including eyeglasses. Any subsequent adjustments made to the assets acquired or liabilities assumed during the measurement period will be recorded as an adjustment to goodwill. The fair value of the net assets acquired from 1-800 CONTACTS included $449.4 of other intangible assets, which primarily consist of finite-lived customer relationships with an amortization period of 13 years and indefinite-lived trade names. The results of operations of 1-800 CONTACTS for the period following June 20, 2012 are included in our consolidated financial statements within our Commercial segment and represented $214.5 and $12.9 of the Company's operating revenue and net income, respectively, for the year ended December 31, 2012. Through December 31, 2012, 1-800 CONTACTS operated under an alliance agreement, or the Alliance, with an unrelated third party to provide for the joint management, marketing and fulfillment of orders for products. Profits and losses of the Alliance were allocated to 1-800 CONTACTS based on the terms set forth in the Alliance agreement. Product sales made by 1-800 CONTACTS are reported on our consolidated income statement within “Other revenue” and expenses for the cost of products sold, as well as certain other allowed expenses as defined in the Alliance agreement, are presented on our consolidated income statement within “Cost of products.” The Alliance terminated on December 31, 2012. The pro-forma effects of this acquisition for prior periods were not material to our consolidated results of operations.
Acquisition of CareMore
On August 22, 2011, we completed our acquisition of CareMore, a senior focused health care delivery program that includes Medicare Advantage plans and clinics designed to deliver proactive, integrated, individualized health care in select California, Arizona and Nevada markets and subsequently expanded into select New York and Virginia markets during 2012. CareMore's leading programs and services provide members with quality care through a hands-on approach to care coordination, convenient neighborhood care centers and exercise facilities and intensive treatment of chronic conditions. We believe this approach enhances our ability to create better health outcomes for seniors by engaging members both on the front end of our relationship, through comprehensive health screenings and enhanced preventive care, and throughout the spectrum of their health care needs. The acquisition of CareMore supports our strategic plans to capitalize on new opportunities for growth in the changing marketplace and to create the best health care value in our industry.

| Restructuring Activities | 4. Restructuring Activities
As a result of restructuring activities implemented during 2012, 2011 and 2010, we recorded liabilities for employee termination costs and lease and other contract exit costs. The restructuring activities are classified as components of general and administrative expenses in the consolidated statements of income for the respective period in which they occurred.
The 2012 restructuring activities were initiated primarily as a result of personnel changes, organizational realignment to create efficiencies in our business processes and certain integration activities associated with the Amerigroup acquisition. Activity related to these liabilities for the year ended December 31, 2012, by segment, is as follows:
The 2011 restructuring activities were initiated as a result of a change in strategic focus primarily in response to Health Care Reform. Activity related to these liabilities for the years ended December 31, 2012 and 2011, by segment, is as follows:
The 2010 restructuring activities were initiated as a result of a change in strategic focus primarily in response Health Care Reform. At December 31, 2012, our total liabilities for 2010 restructuring activities were $7.6, of which $2.6 related to employee termination costs and $5.0 related to lease and other contract exit costs.

| Investments | 5. Investments
A summary of current and long-term investments, available-for-sale, at December 31, 2012 and 2011 is as follows:
At December 31, 2012, we owned $2,650.5 of mortgage-backed securities and $207.3 of asset-backed securities out of a total available-for-sale investment portfolio of $18,586.9. These securities included sub-prime and Alt-A securities with fair values of $44.4 and $133.7, respectively. These sub-prime and Alt-A securities had accumulated net unrealized gains of $1.1 and $6.2, respectively. The average credit rating of the sub-prime and Alt-A securities was “BB” and “CCC”, respectively. The following tables summarize for fixed maturity securities and equity securities in an unrealized loss position at December 31, 2012 and 2011, the aggregate fair value and gross unrealized loss by length of time those securities have been continuously in an unrealized loss position.
The amortized cost and fair value of fixed maturity securities at December 31, 2012, by contractual maturity, are shown below. Expected maturities may be less than contractual maturities because the issuers of the securities may have the right to prepay obligations without prepayment penalties.
The major categories of net investment income for the years ended December 31 are as follows:
Net realized investment gains/losses and net change in unrealized appreciation/depreciation in investments for the years ended December 31 are as follows:
A primary objective in the management of our fixed maturity and equity portfolios is to maximize total return relative to underlying liabilities and respective liquidity needs. In achieving this goal, assets may be sold to take advantage of market conditions or other investment opportunities as well as tax considerations. Sales will generally produce realized gains and losses. In the ordinary course of business, we may sell securities at a loss for a number of reasons, including, but not limited to: (i) changes in the investment environment; (ii) expectations that the fair value could deteriorate further; (iii) desire to reduce exposure to an issuer or an industry; (iv) changes in credit quality; or (v) changes in expected cash flow. During the year ended December 31, 2012, we sold $14,098.6 of investments which resulted in gross realized gains of $483.0 and gross realized losses of $148.6.
A significant judgment in the valuation of investments is the determination of when an other-than-temporary decline in value has occurred. We follow a consistent and systematic process for recognizing impairments on securities that sustain other-than-temporary declines in value. We have established a committee responsible for the impairment review process. The decision to impair a security incorporates both quantitative criteria and qualitative information. The impairment review process considers a number of factors including, but not limited to: (i) the length of time and the extent to which the fair value has been less than book value, (ii) the financial condition and near term prospects of the issuer, (iii) our intent and ability to retain impaired equity security investments for a period of time sufficient to allow for any anticipated recovery in fair value, (iv) our intent to sell or the likelihood that we will need to sell a fixed maturity security before recovery of its amortized cost basis, (v) whether the debtor is current on interest and principal payments, (vi) the reasons for the decline in value (i.e., credit event compared to liquidity, general credit spread widening, currency exchange rate or interest rate factors) and (vii) general market conditions and industry or sector specific factors. For securities that are deemed to be other-than-temporarily impaired, the security is adjusted to fair value and the resulting losses are recognized in realized gains or losses in the consolidated statements of income. The new cost basis of the impaired securities is not increased for future recoveries in fair value.
Other-than-temporary impairments recorded in 2012, 2011 and 2010 were primarily the result of the continued credit deterioration on specific issuers in the bond markets and certain equity securities' fair values remaining below cost for an extended period of time. There were no individually significant other-than-temporary impairment losses on investments by issuer during 2012, 2011 or 2010.
Investment securities are exposed to various risks, such as interest rate, market and credit. Due to the level of risk associated with certain investment securities and the level of uncertainty related to changes in the value of investment securities, it is possible that changes in these risk factors in the near term could have an adverse material impact on our results of operations or shareholders' equity.
The changes in the amount of the credit component of other-than-temporary impairment losses on fixed maturity securities recognized in income, for which a portion of the other-than-temporary impairment losses was recognized in other comprehensive income, was not material for the years ended December 31, 2012, 2011 or 2010.
At December 31, 2012 and 2011, no investments exceeded 10% of shareholders' equity.
The carrying value of fixed maturity investments that did not produce income during 2012 and 2011 was $1.8 and $11.9 at December 31, 2012 and 2011, respectively.
As of December 31, 2012 we had committed approximately $288.1 to future capital calls from various third-party investments in exchange for an ownership interest in the related entity.
At December 31, 2012 and 2011, securities with carrying values of approximately $431.5 and $246.8, respectively, were deposited by our insurance subsidiaries under requirements of regulatory authorities. |

Cash Flow Hedges
We have historically entered into forward starting pay fixed interest rate swaps, with the objective of eliminating the variability of cash flows in the interest payments on various debt issuances. These swaps have all terminated and no amounts were outstanding at December 31, 2012 or 2011. The unrecognized loss for all terminated cash flow hedges included in accumulated other comprehensive income was $35.3 at December 31, 2012 and 2011. As of December 31, 2012, the total amount of amortization over the next twelve months for all cash flow hedges will increase interest expense by approximately $4.6.
A summary of the effect of cash flow hedges on our financial statements for the years ended December 31, 2012, 2011 and 2010 is as follows:
We test for cash flow hedge effectiveness at hedge inception and re-assess at the end of each reporting period. No amounts were excluded from the assessment of hedge effectiveness.

| Fair Value | 7. Fair Value
Assets and liabilities recorded at fair value in the consolidated balance sheets are categorized based upon the level of judgment associated with the inputs used to measure their fair value. Level inputs, as defined by FASB guidance for fair value measurements and disclosures, are as follows:
The following methods, assumptions and inputs were used to determine the fair value of each class of the following assets and liabilities recorded at fair value in the consolidated balance sheets:
Cash equivalents: Cash equivalents primarily consist of highly rated money market funds with maturities of three months or less, and are purchased daily at par value with specified yield rates. Due to the high ratings and short-term nature of the funds, we designate all cash equivalents as Level I.
Fixed maturity securities, available-for-sale: Fair values of available-for-sale fixed maturity securities are based on quoted market prices, where available. These fair values are obtained primarily from third party pricing services, which generally use Level I or Level II inputs for the determination of fair value to facilitate fair value measurements and disclosures. United States Government securities represent Level I securities, while Level II securities primarily include corporate securities, securities from states, municipalities and political subdivisions and mortgage-backed securities. For securities not actively traded, the third party pricing services may use quoted market prices of comparable instruments or discounted cash flow analyses, incorporating inputs that are currently observable in the markets for similar securities. We have controls in place to review the third party pricing services' qualifications and procedures used to determine fair values. In addition, we periodically review the third party pricing services' pricing methodologies, data sources and pricing inputs to ensure the fair values obtained are reasonable. Inputs that are often used in the valuation methodologies include, but are not limited to, broker quotes, benchmark yields, credit spreads, default rates and prepayment speeds. We also have certain fixed maturity securities, primarily corporate debt and other fixed maturity securities, that are designated Level III securities. For these securities, the valuation methodologies may incorporate broker quotes or assumptions for benchmark yields, credit spreads, default rates and prepayment speeds that are not observable in the markets.
Equity securities, available-for-sale: Fair values of equity securities are generally designated as Level I and are based on quoted market prices. For certain equity securities, quoted market prices for the identical security are not always available and the fair value is estimated by reference to similar securities for which quoted prices are available. These securities are designated Level II. We also have certain equity securities, including private equity securities, for which the fair value is estimated based on each security's current condition and future cash flow projections. Such securities are designated Level III. The fair values of these private equity securities are generally based on either broker quotes or discounted cash flow projections using assumptions for inputs such as the weighted-average cost of capital, long-term revenue growth rates and earnings before interest, taxes, depreciation and amortization, or EBITDA, and/or revenue multiples that are not observable in the markets.
Other invested assets, current: Other invested assets, current include securities held in rabbi trusts that are classified as trading. Fair values are based on quoted market prices.
Securities lending collateral: Fair values of securities lending collateral are based on quoted market prices, where available. These fair values are obtained primarily from third party pricing services, which generally use Level I or Level II inputs, for the determination of fair value to facilitate fair value measurements and disclosures.
Derivatives - interest rate swaps: Fair values are based on the quoted market prices by the financial institution that is the counterparty to the swap. We independently verify prices provided by the counterparties using valuation models that incorporate market observable inputs for similar interest rate swaps.
In addition, the following methods and assumptions were used to determine the fair value of each class of pension benefit plan assets and other benefit plan assets not defined above (see Note 11, “Retirement Benefits,” for fair values of benefit plan assets):
Mutual funds: Fair values are based on quoted market prices, which represent the net asset value, or NAV, of shares held.
Common and collective trusts: Fair values of common/collective trusts that replicate traded money market funds are based on cost, which approximates fair value. Fair values of common/collective trusts that invest in securities are valued at the NAV of the shares held, where the trust applies fair value measurements to the underlying investments to determine the NAV.
Partnership interests: Fair values are estimated based on the plan's proportionate share of the undistributed partners' capital as reported in audited financial statements of the partnership.
Contract with insurance company: Fair value of the contract in the insurance company general investment account is determined by the insurance company based on the fair value of the underlying investments of the account.
Investment in DOL 103-12 trust: Fair value is based on the plan's proportionate share of the fair value of investments held by the trust, qualified as a Department of Labor Regulation 2520.103-12 entity, or DOL 103-12 trust, as reported in audited financial statements of the trust, where the trustee applies fair value measurements to the underlying investments of the trust.
Life insurance contracts: Fair value is based on the cash surrender value of the policies as reported by the insurer. A summary of fair value measurements by level for assets and liabilities measured at fair value on a recurring basis at December 31, 2012 and December 31, 2011 is as follows:
A reconciliation of the beginning and ending balances of assets measured at fair value on a recurring basis using Level III inputs for the years ended December 31, 2012, 2011 and 2010 is as follows:
Transfers between levels, if any, are recorded as of the beginning of the reporting period. During the year ended December 31, 2012, certain securities, primarily equity securities, that were previously classified as Level II were transferred into Level III as a result of previously observable inputs becoming unobservable due to market inactivity. During the year ended December 31, 2012, the transfers out of Level III of corporate securities and commercial mortgage-backed securities were for certain sub-prime securities transferred from Level III to Level II as a result of inputs that were previously unobservable becoming observable due to increased volume and level of trading in active markets. In addition, the transfers out of Level III of other debt securities were for certain inverse floating rate securities transferred from Level III to Level II as a result of those securities' impending maturity and settlement and recent trading activity of similar securities in observable markets.
During the year ended December 31, 2012, there were no transfers from Level I to Level II or from Level II to Level I.
There were no material transfers between Levels I, II or III during the years ended December 31, 2011 or 2010.
Certain assets and liabilities are measured at fair value on a nonrecurring basis; that is, the instruments are not measured at fair value on an ongoing basis but are subject to fair value adjustments only in certain circumstances. As disclosed in Note 3, “Business Combinations”, we completed our acquisitions of Amerigroup, 1-800 CONTACTS and CareMore on December 24, 2012, June 20, 2012 and August 22, 2011, respectively. The values of net assets acquired in our acquisitions of Amerigroup, 1-800 CONTACTS and CareMore and resulting goodwill and other intangible assets were recorded at fair value primarily using Level III inputs. The majority of Amerigroup, 1-800 CONTACTS and CareMore's assets acquired and liabilities assumed were recorded at their carrying values as of the respective dates of acquisition, as their carrying values approximated their fair values due to their short-term nature. The fair values of goodwill and other intangible assets acquired in our acquisitions of Amerigroup, 1-800 CONTACTS and CareMore were internally estimated based on the income approach. The income approach estimates fair value based on the present value of the cash flows that the assets can be expected to generate in the future. We developed internal estimates for the expected cash flows and discount rate in the present value calculation. Refer to Note 13, “Debt,” for additional disclosure regarding the Amerigroup senior unsecured notes recorded at their acquisition date fair value during 2012 (nonrecurring fair value measurement). Other than the assets acquired and liabilities assumed in our acquisitions of Amerigroup, 1-800 CONTACTS and CareMore described above, there were no other assets or liabilities measured at fair value on a nonrecurring basis during the years ended December 31, 2012, 2011 and 2010.
Our valuation policy is determined by members of our treasury and accounting departments. Whenever possible, our policy is to obtain quoted market prices in active markets to estimate fair values for recognition and disclosure purposes. Where quoted market prices in active markets are not available, fair values are estimated using discounted cash flow analyses, broker quotes or other valuation techniques. These techniques are significantly affected by our assumptions, including discount rates and estimates of future cash flows. Potential taxes and other transaction costs are not considered in estimating fair values. Our valuation policy is generally to obtain only one quoted price for each security from third party pricing services, which are derived through recently reported trades for identical or similar securities making adjustments through the reporting date based upon available market observable information. When broker quotes are used, we generally obtain only one broker quote per security. As we are responsible for the determination of fair value, we perform monthly analysis on the prices received from third parties to determine whether the prices are reasonable estimates of fair value. This analysis is performed by our internal treasury personnel who are familiar with our investment portfolios, the third party pricing services engaged and the valuation techniques and inputs used. Our analysis includes a review of month-to-month price fluctuations. If unusual fluctuations are noted in this review, we may obtain additional information from other pricing services to validate the quoted price. There were no adjustments to quoted market prices obtained from third party pricing services during the years ended December 31, 2012, 2011 or 2010.
In addition to the preceding disclosures on assets recorded at fair value in the consolidated balance sheets, FASB guidance also requires the disclosure of fair values for certain other financial instruments for which it is practicable to estimate fair value, whether or not such values are recognized in the consolidated balance sheets.
Non-financial instruments such as real estate, property and equipment, other current assets, deferred income taxes and intangible assets, and certain financial instruments such as policy liabilities are excluded from the fair value disclosures. Therefore, the fair value amounts cannot be aggregated to determine our underlying economic value.
The carrying amounts reported in the consolidated balance sheets for cash, accrued investment income, premium and self-funded receivables, other receivables, unearned income, accounts payable and accrued expenses, income taxes payable, security trades pending payable, securities lending payable and certain other current liabilities approximate fair value because of the short term nature of these items. These assets and liabilities are not listed in the table below.
The following methods and assumptions were used to estimate the fair value of each class of financial instrument:
Other invested assets, long-term: Other invested assets, long-term include primarily our investments in limited partnerships, joint ventures and other non-controlled corporations, as well as the cash surrender value of corporate-owned life insurance policies. Investments in limited partnerships, joint ventures and other non-controlled corporations are carried at our share in the entities' undistributed earnings, which approximates fair value. The carrying value of corporate-owned life insurance policies represents the cash surrender value as reported by the respective insurer.
Short-term borrowings: The fair value of our short-term borrowings is based on quoted market prices for the same or similar debt, or, if no quoted market prices were available, on the current market interest rates estimated to be available to us for debt of similar terms and remaining maturities.
Long-term debt – commercial paper: The carrying amount for commercial paper approximates fair value as the underlying instruments have variable interest rates at market value.
Long-term debt – notes and capital leases: The fair values of our notes are based on quoted market prices in active markets for the same or similar debt, or, if no quoted market prices are available, on the current market observable rates estimated to be available to us for debt of similar terms and remaining maturities. Capital leases are classified as Level III and are carried at the unamortized present value of the minimum lease payments, which approximates fair value.
Long-term debt – convertible debentures: The fair value of our convertible debentures is based on the quoted market price in the active private market in which the convertible debentures trade.
A summary of the carrying value and fair value by level of financial instruments not recorded at fair value on our consolidated balance sheet at December 31, 2012 are as follows:
A summary of the carrying value and fair value of financial instruments not recorded at fair value on our consolidated balance sheet at December 31, 2011 are as follows:

| Income Taxes | 8. Income Taxes
The components of deferred income taxes at December 31 are as follows:
Changes in the valuation allowance during 2012 included an $11.0 release related to federal credits and loss carryforwards as tax settlements were completed and establishment of an $18.1 allowance related to state net operating losses net of the federal benefit.
Significant components of the provision for income taxes for the years ended December 31 consist of the following:
State and local current tax expense is reported gross of federal benefit, and includes amounts related to true up of prior years' tax, audit settlements, uncertain tax positions and state tax credits. Such items are included in multiple lines in the following rate reconciliation table on a net of federal tax basis.
A reconciliation of income tax expense recorded in the consolidated statements of income and amounts computed at the statutory federal income tax rate for the years ended December 31, is as follows:
During the year ended December 31, 2012, we recognized income tax benefits of $200.5, or $0.62 per diluted share, for settlement of certain of our open tax issues with the Internal Revenue Service, or IRS, following approval by the Joint Committee on Taxation. This included amounts related to not-for-profit conversion and corporate reorganizations in prior years, as well as amounts associated with issues related to certain of our acquired companies. This income tax benefit includes the release of gross unrecognized tax benefits from uncertain tax positions, discussed below, release of a valuation allowance, discussed above, and recognition of interest income. This income tax benefit, and resulting decrease in the effective tax rate, was partially offset due to the non-tax deductibility of litigation settlement expenses associated with the settlement of a class action lawsuit in June 2012 and an increase in our state deferred tax asset valuation allowance attributable to the uncertainty associated with some of our state net operating loss carryforwards.
During the year ended December 31, 2011, following approval by the Joint Committee on Taxation, we settled the audit of our 2003 and 2004 (short year) federal tax returns, which had been in the appeals process with the IRS. This resulted in a tax benefit of $39.3. In addition, during the year ended December 31, 2011, we completed a state tax examination, resulting in additional tax benefits for audit settlements of $10.4.
The change in the carrying amount of gross unrecognized tax benefits from uncertain tax positions for the years ended December 31, is as follows:
In the table above, certain amounts for the year ended December 31, 2011 have been reclassified from a net to gross presentation to more fully reflect estimated tax benefits that could potentially be settled with taxing authorities in future periods, including for the year ended December 31, 2012. This reclassification does not impact amounts presented in the financial statements.
The table above excludes interest, net of related tax benefits, which is treated as income tax expense (benefit) under our accounting policy. The interest is included in the amounts described in the following paragraph.
As of December 31, 2012, $103.0 of unrecognized tax benefits would impact our effective tax rate in future periods, if recognized. Also included is $4.7 that would be recognized as an adjustment to additional paid-in capital and would not affect our effective tax rate. The December 31, 2012 balance includes $0.8 of tax positions for which ultimate deductibility is highly certain but for which there is uncertainty about the timing of such deductibility. Excluding the impact of interest and penalties, the disallowance of the shorter deductibility period would not affect our effective tax rate, but would accelerate the payment of cash to the taxing authority to an earlier period.
For the years ended December 31, 2012, 2011 and 2010, we recognized approximately $(9.0), $(0.1) and $(2.9) in interest, respectively. We had accrued approximately $15.7 and $24.7 for the payment of interest at December 31, 2012 and 2011, respectively.
As of December 31, 2012, as further described below, certain tax years remain open to examination by the IRS and various state and local authorities. In addition, we continue to discuss certain industry issues with the IRS. As a result of these examinations and discussions, we have recorded amounts for uncertain tax positions. It is anticipated that the amount of unrecognized tax benefits will change in the next twelve months due to possible settlements of audits and changes in temporary items. However, the ultimate resolution of these items is dependent on the completion of negotiations with various taxing authorities. While it is difficult to determine when other tax settlements will actually occur, it is reasonably possible that one could occur in the next twelve months and our unrecognized tax benefits could change within a range of approximately $12.4 to $(95.3).
We are a member of the IRS Compliance Assurance Process, or CAP. The objective of CAP is to reduce taxpayer burden and uncertainty while assuring the IRS of the accuracy of tax returns prior to filing, thereby reducing or eliminating the need for post-filing examinations.
As of December 31, 2012, the examinations of our 2011 through 2004 tax years continue to be in process. Many of the issues in open tax years have been resolved and we have received Closing Agreements from the IRS relating to most of the significant issues. Issues resolved include items related to not-for-profit conversion and corporate reorganizations in prior years, as well as issues related to certain of our acquired companies. However, the Closing Agreements impact multiple tax years and will generate refunds in later years, and therefore require approval from the Joint Committee on Taxation before they can be finalized and settled. While we cannot be certain, we anticipate the closing of many of the open tax years' examinations and receipt of related tax refunds during 2013.
In certain states, we pay premium taxes in lieu of state income taxes. Premium taxes are reported with general and administrative expense.
At December 31, 2012, we had unused federal tax net operating loss carryforwards of approximately $63.7 to offset future taxable income. The loss carryforwards expire in the years 2015 through 2024. During 2012, 2011 and 2010 federal income taxes paid totaled $1,188.2, $1,153.9 and $2,531.9, respectively. |

| Property And Equipment | 9. Property and Equipment
A summary of property and equipment at December 31 is as follows:
Property and equipment includes assets purchased under noncancelable capital leases at December 31, 2012 and 2011 was $59.0. Total accumulated amortization on leased assets at December 31, 2012 and 2011 was $59.0 and $58.5, respectively. Depreciation expense for 2012, 2011 and 2010 was $107.1, $95.7 and $103.1, respectively. Amortization expense on leased assets, computer software and leasehold improvements for 2012, 2011 and 2010 was $261.9, $204.6 and $194.3, respectively, which includes amortization expense on computer software, both purchased and internally developed, for 2012, 2011 and 2010 of $240.7, $183.9 and $171.9, respectively. Capitalized costs related to the internal development of software of $1,332.1 and $1,022.2 at December 31, 2012 and 2011, respectively, are reported with computer software.
During the year ended December 31, 2012, we recognized $66.8 of impairments related to computer software (primarily internally developed) due to project cancellation or asset replacement, some of which resulted from a change in strategic focus needed to effectively manage business operations in a post-Health Care Reform environment.
During the year ended December 31, 2010, we recognized $95.3 of impairments of information technology assets related to our change in strategic focus primarily in response to Health Care Reform and due to our decision to discontinue further use of certain assets in the normal course of business. |

| Goodwill And Other Intangible Assets | 10. Goodwill and Other Intangible Assets
A summary of the change in the carrying amount of goodwill by reportable segment (see Note 20, “Segment Information”) for 2012 and 2011 is as follows:
Goodwill adjustments incurred during 2012 included reductions totaling $0.4 related to the tax benefit on the exercise of stock options issued as part of various acquisitions and $1.6 related to other measurement period adjustments. Goodwill adjustments incurred during 2011 included a reduction of $1.5 related to the tax benefit on the exercise of stock options issued as part of various acquisitions.
As required by FASB guidance, we completed annual impairment tests of existing goodwill and other intangible assets with indefinite lives during 2012, 2011 and 2010. These annual impairment tests are performed by us during the fourth quarter. FASB guidance also requires interim impairment testing to be performed when potential impairment indicators exist. These tests involve the use of estimates related to the fair value of goodwill and intangible assets with indefinite lives and require a significant degree of management judgment and the use of subjective assumptions. The fair values were estimated using the income and market value valuation methods, incorporating Level III internal estimates for inputs, including, but not limited to, revenue projections, income projections, cash flows and discount rates. The components of other intangible assets as of December 31 are as follows:
During 2010, we recognized an impairment charge of $21.1 for certain intangible assets associated with the UniCare provider networks, due to a decision we made to transfer certain membership to an alternative network.
As of December 31, 2012, estimated amortization expense for each of the five years ending December 31, is as follows: 2013, $266.9; 2014, $233.4; 2015, $200.4; 2016, $167.9; 2017, $146.3. |

| Retirement Benefits | 11. Retirement Benefits
We sponsor various non-contributory employee defined benefit plans through certain subsidiaries.
The WellPoint Cash Balance Pension Plan, or the WellPoint Plan, is a cash balance pension plan covering certain eligible employees of the affiliated companies that participate in the WellPoint Plan. Effective January 1, 2006, benefits were curtailed, with the result that most participants stopped accruing benefits but continue to earn interest on benefits accrued prior to the curtailment. Certain participants subject to collective bargaining and certain other participants who met grandfathering rules continue to accrue benefits. Several pension plans acquired through various corporate mergers and acquisitions have been merged into the WellPoint Plan. Effective January 1, 2011, we split the WellPoint Plan, with no change in benefits for any participant. Current employees who are still receiving credits and/or benefit accruals were placed into a new plan, the WellPoint Cash Balance Pension Plan B. All other participants remain in the WellPoint Plan.
The UGS Pension Plan is a defined benefit pension plan with a cash balance component. The UGS Pension Plan covers eligible employees of the affiliated companies that participate in the UGS Pension Plan. Effective January 1, 2004, benefits were curtailed, with the result that most participants stopped accruing benefits but continue to earn interest on benefits previously accrued. Certain employees subject to collective bargaining and certain other employees who met grandfathering rules continue to accrue benefits.
The Employees' Retirement Plan of Blue Cross of California, or the BCC Plan, is a defined benefit pension plan that covers eligible employees of Blue Cross of California who are covered by a collective bargaining agreement. Effective January 1, 2007, benefits were curtailed under the BCC Plan with the result that no Blue Cross of California employees hired or rehired after December 31, 2006 are eligible to participate in the BCC Plan.
All of the plans' assets consist primarily of common stocks, fixed maturity securities, investment funds and short-term investments. The funding policies for all plans are to contribute amounts at least sufficient to meet the minimum funding requirements set forth in the Employee Retirement Income Security Act of 1974, as amended, or ERISA, including amendment by the Pension Protection Act of 2006, and in accordance with income tax regulations, plus such additional amounts as are necessary to provide assets sufficient to meet the benefits to be paid to plan participants.
We use a December 31 measurement date for determining benefit obligations and fair value of plan assets.
The following tables disclose consolidated “pension benefits,” which include the defined benefit pension plans described above, and consolidated “other benefits,” which include postretirement health and welfare benefits including medical, vision and dental benefits offered to certain employees. Calculations were computed using assumptions at the December 31 measurement dates.
The reconciliation of the benefit obligation is as follows:
The changes in the fair value of plan assets are as follows:
The net amount included in the consolidated balance sheets is as follows:
The net amounts included in accumulated other comprehensive loss (income) that have not been recognized as components of net periodic benefit costs are as follows:
The estimated net actuarial loss and prior service credit for the defined benefit pension plans that will be reclassified from accumulated other comprehensive loss into net periodic benefit costs over the next year are $33.1 and $0.8, respectively. The estimated net actuarial loss and prior service credit for postretirement benefit plans that will be reclassified from accumulated other comprehensive loss into net periodic benefit costs over the next year are $10.7 and $13.3, respectively.
The accumulated benefit obligation for the defined benefit pension plans was $1,941.8 and $1,844.8 at December 31, 2012 and 2011, respectively.
As of December 31, 2012, certain pension plans had accumulated benefit obligations in excess of plan assets. For those same plans, the projected benefit obligation was also in excess of plan assets. Such plans had a combined projected benefit obligation, accumulated benefit obligation and fair value of plan assets of $1,414.9, $1,410.2 and $1,282.3, respectively.
The weighted-average assumptions used in calculating the benefit obligations for all plans are as follows:
The components of net periodic benefit cost included in the consolidated statements of income are as follows:
During the years ended December 31, 2012, 2011 and 2010 we incurred total settlement losses of $13.8, $21.3 and $31.1, respectively, as lump-sum payments exceeded the service cost and interest cost components of net periodic benefit cost for certain of our plans.
The weighted-average assumptions used in calculating the net periodic benefit cost for all plans are as follows:
The assumed health care cost trend rates used to measure the expected cost of pre-Medicare (those who are not currently eligible for Medicare benefits) other benefits at our December 31, 2012 measurement dates was 8.00% for 2013 with a gradual decline to 4.50% by the year 2025. The assumed health care cost trend rates used to measure the expected cost of post-Medicare (those who are currently eligible for Medicare benefits) other benefits at our December 31, 2012 measurement dates was 6.00% for 2013 with a gradual decline to 4.50% by the year 2021. These estimated trend rates are subject to change in the future. The health care cost trend rate assumption has a significant effect on the amounts reported. For example, an increase in the assumed health care cost trend rate of one percentage point would increase the postretirement benefit obligation as of December 31, 2012 by $47.1 and would increase service and interest costs by $2.4. Conversely, a decrease in the assumed health care cost trend rate of one percentage point would decrease the postretirement benefit obligation by $40.2 as of December 31, 2012 and would decrease service and interest costs by $2.0.
Plan assets include a diversified mix of investment grade fixed maturity securities, equity securities and alternative investments across a range of sectors and levels of capitalization to maximize the long-term return for a prudent level of risk. The weighted-average target allocation for pension benefit plan assets is 45% equity securities, 46% fixed maturity securities, and 9% to all other types of investments. Equity securities primarily include a mix of domestic securities, foreign securities and mutual funds invested in equities. Fixed maturity securities primarily include treasury securities, corporate bonds, and asset-backed investments issued by corporations and the U.S. government. Other types of investments include partnership interests, collective trusts that replicate money market funds and insurance contracts designed specifically for employee benefit plans. As of December 31, 2012, there were no significant concentrations of investments in the pension benefit assets or other benefit assets. No plan assets were invested in WellPoint common stock.
Pension benefit assets and other benefit assets recorded at fair value are categorized based upon the level of judgment associated with the inputs used to measure their fair value. The fair values of our pension benefit assets and other benefit assets at December 31, 2012, excluding $3.2 of cash, investment income receivable and amounts due to/from brokers, by asset category and level inputs, as defined by FASB guidance regarding fair value measurements and disclosures (see Note 7, “Fair Value,” for additional information regarding the definition of level inputs), are as follows:
The fair values of our pension benefit assets and other benefit assets at December 31, 2011, excluding $(41.6) of cash, investment income receivable and amounts due to/from brokers, by asset category and level inputs, as defined by FASB guidance regarding fair value measurements and disclosures (see Note 7, “Fair Value,” for additional information regarding the definition of level inputs) are as follows:
A reconciliation of the beginning and ending balances of plan assets measured at fair value using Level III inputs for the years ended December 31, 2012, 2011 and 2010 is as follows:
There were no material transfers between Levels I, II and III during the years ended December 31, 2012, 2011 and 2010. The significant decline in plan assets measured using Level III inputs as of December 31, 2012 was primarily due to the sale of an equity partnership.
Our current funding strategy is to fund an amount at least equal to the minimum required funding as determined under ERISA with consideration of maximum tax deductible amounts. We may elect to make discretionary contributions up to the maximum amount deductible for income tax purposes. For the years ended December 31, 2012 or 2011, no material contributions were necessary to meet ERISA required funding levels. However, during the year ended December 31, 2012, we made tax deductible discretionary contributions to the pension benefit plans of $34.5. During the year ended December 31, 2011, we made tax deductible discretionary contributions to the pension benefit plans and other benefit plans of $57.7 and $30.0, respectively. Employer contributions to other benefit plans represent discretionary contributions and do not include payments to retirees for current benefits.
Our estimated future payments for pension benefits and postretirement benefits, which reflect expected future service, as appropriate, are as follows:
In addition to the defined benefit plans, we maintain the WellPoint 401(k) Retirement Savings Plan, CareMore 401(k) Pension Plan, 1-800 CONTACTS Retirement and Savings Plan and the Amerigroup Retirement Savings Plan which are qualified defined contribution plans covering substantially all employees. Voluntary employee contributions are matched by us subject to certain limitations. Contributions made by us totaled $91.0, $87.8 and $120.7 during 2012, 2011 and 2010, respectively. |

| Medical Claims Payable | 12. Medical Claims Payable
A reconciliation of the beginning and ending balances for medical claims payable for the years ended December 31 is as follows:
Amounts incurred related to prior years vary from previously estimated liabilities as the claims are ultimately settled. Liabilities at any period end are continually reviewed and re-estimated as information regarding actual claims payments, or runout, becomes known. This information is compared to the originally established year end liability. Negative amounts reported for incurred medical claims related to prior years result from claims being settled for amounts less than originally estimated. The prior year redundancy of $513.6 shown above for the year ended December 31, 2012 represents an estimate based on paid claim activity from January 1, 2012 to December 31, 2012. Medical claim liabilities are usually described as having a “short tail,” which means that they are generally paid within twelve months of the member receiving service from the provider. Accordingly, the majority of the $513.6 redundancy relates to claims incurred in calendar year 2011.
The following table provides a summary of the two key assumptions having the most significant impact on our incurred but not paid liability estimates for the years ended December 31, 2012, 2011 and 2010, which are the completion and trend factors. These two key assumptions can be influenced by utilization levels, unit costs, mix of business, benefit plan designs, provider reimbursement levels, processing system conversions and changes, claim inventory levels, claim processing patterns, claim submission patterns and operational changes resulting from business combinations.
The favorable development recognized in 2012 resulted primarily from trend factors in late 2011 developing more favorably than originally expected as well as a smaller but significant contribution from completion factor development. The favorable development recognized in 2011 was driven by trend factors in late 2010 developing more favorably than originally expected. This impact was partially offset by completion factors developing unfavorably due to slight increases in payment cycle times. The favorable development recognized in 2010 was driven by trend factors in late 2009 developing more favorably than originally expected. In addition, a minor but steady improvement in payment cycle times impacted completion factor development and contributed to the favorability.
Due to changes within our Company and industry during 2010, we re-evaluated our actuarial processes and resulting levels of reserves. As discussed in Note 2, “Basis of Presentation and Significant Accounting Policies,” Actuarial Standards of Practice require that claims liabilities be appropriate under moderately adverse circumstances. To satisfy these requirements, our reserving process has historically involved recognizing the inherent volatility in actual future claim payments compared to the current estimate for the related liability by recording a provision for adverse deviation. This additional reserve establishes a sufficient level of conservatism in the liability estimate that is similar from period to period. There are a number of factors that can require a higher or lower level of additional reserve, such as changes in technology that provide faster access to claims data or change the speed of adjudication and settlement of claims, or overall variability in claim payment patterns and claim inventory levels. Given that in the more recent periods we experienced higher levels of automatic claims adjudication and faster claims payment leading to lower and more consistent claims inventory levels, we determined that using a lower level of targeted reserve for adverse deviation provides a similar level of confidence that the established reserves are appropriate in the current environment. This change in estimate resulted in a benefit to 2010 income before income tax expense and diluted earnings per share of $67.7 and $0.11, respectively. We continued to use this lower level of targeted reserve for adverse deviation in 2011 and 2012. |

| Debt | 13. Debt
Short-term Borrowings
We are a member, through certain subsidiaries, of the Federal Home Loan Bank of Indianapolis and the Federal Home Loan Bank of Cincinnati, collectively, the FHLBs, and as a member we have the ability to obtain short-term cash advances subject to certain minimum collateral requirements. At December 31, 2012 and 2011, $250.0 and $100.0, respectively, were outstanding under our short-term FHLBs borrowings. These outstanding short-term FHLBs borrowings at December 31, 2012 and 2011 had fixed interest rates of 0.206% and 0.260%, respectively. Long-term Debt
The carrying value of long-term debt at December 31 consists of the following:
All long-term debt shown above is a direct obligation of WellPoint, Inc., except for the Amerigroup debt described below, the surplus notes, the FHLBs secured loan and capital leases.
As a result of our acquisition of Amerigroup on December 24, 2012, the carrying amount of Amerigroup's $475.0 of 7.500% senior unsecured notes due 2019 have been included in our consolidated balance sheet as of December 31, 2012. In accordance with FASB accounting guidance for business combinations, the notes were recorded at their estimated fair value of $556.9 on the date of acquisition. The fair value of the notes was estimated based on the most recent quoted market price for the notes, which we consider to be a Level II input in accordance with FASB guidance for fair value measurements. On January 25, 2013 we redeemed the outstanding principal balance of these notes, plus applicable premium for early redemption, for cash totaling $555.6. The weighted-average redemption price of the notes was approximately 117% of the principal amount outstanding. On September 10, 2012, we issued $625.0 of 1.250% notes due 2015, $625.0 of 1.875% notes due 2018, $1,000.0 of 3.300% notes due 2023 and $1,000.0 of 4.650% notes due 2043 under our shelf registration statement. We used the net proceeds of this offering to pay a portion of the consideration for our acquisition of Amerigroup and the balance for general corporate purposes. The notes have a call feature that allows us to repurchase the notes at any time at our option and a put feature that allows a note holder to require us to repurchase the notes upon the occurrence of both a change in control event and a downgrade of the notes below an investment grade rating. At maturity on August 1, 2012, we repaid the $800.0 outstanding balance of our 6.800% senior unsecured notes. On May 7, 2012, we issued $850.0 of 3.125% notes due 2022 and $900.0 of 4.625% notes due 2042 under our shelf registration statement. We used the proceeds from this offering for working capital and for general corporate purposes, including, but not limited to, repayment of short-term and long-term debt. The notes have a call feature that allows us to repurchase the notes at any time at our option and a put feature that allows a note holder to require us to repurchase the notes upon the occurrence of both a change in control event and a downgrade of the notes below an investment grade rating. At maturity on April 9, 2012, we refinanced the $100.0 outstanding balance of our long-term 1.430% fixed rate FHLB secured loan to a three month term loan with a fixed interest rate of 0.370% which matured on July 9, 2012.
At maturity on January 17, 2012, we repaid the $350.0 outstanding balance of our 6.375% senior unsecured notes.
On August 15, 2011, we issued $400.0 of 2.375% senior unsecured notes due 2017 and $700.0 of 3.700% senior unsecured notes due 2021 under our shelf registration statement. A portion of the proceeds from this debt issuance was used to fund the purchase price of our acquisition of CareMore and the remaining proceeds were used for working capital and for general corporate purposes, including, but not limited to repayment of short-term and long-term debt. The notes have a call feature that allows us to redeem the notes at any time at our option and a put feature that allows a note holder to require us to repurchase the notes upon the occurrence of both a change of control event and a ratings downgrade of the notes.
At maturity on January 15, 2011, we repaid the $700.0 outstanding balance of our 5.000% senior unsecured notes. Surplus notes are unsecured obligations of Anthem Insurance Companies, Inc., or Anthem Insurance, a wholly owned subsidiary, and are subordinate in right of payment to all of Anthem Insurance's existing and future indebtedness. Any payment of interest or principal on the surplus notes may be made only with the prior approval of the Indiana Department of Insurance, or IDOI, and only out of capital and surplus funds of Anthem Insurance that the IDOI determines to be available for the payment under Indiana insurance laws.
We have a senior credit facility, or the facility, with certain lenders for general corporate purposes. The facility, as amended, provides credit up to $2,000.0 and matures on September 29, 2016. The interest rate on the facility is based on either, (i) the LIBOR rate plus a predetermined percentage rate based on our credit rating at the date of utilization, or (ii) a base rate as defined in the facility agreement plus a predetermined percentage rate based on our credit rating at the date of utilization. Our ability to borrow under the facility is subject to compliance with certain covenants. There were no amounts outstanding under the facility as of December 31, 2012.
We have an authorized commercial paper program of up to $2,500.0, the proceeds of which may be used for general corporate purposes. The weighted-average interest rate on commercial paper borrowings at December 31, 2012 and 2011 was 0.396% and 0.442%, respectively. Commercial paper borrowings have been classified as long-term debt at December 31, 2012 and 2011 as our practice and intent is to replace short-term commercial paper outstanding at expiration with additional short-term commercial paper for an uninterrupted period extending for more than one year and we have the ability to redeem our commercial paper with borrowings under the senior credit facility described above.
Convertible Debentures
On October 9, 2012, we issued $1,500.0 of senior convertible debentures, or the Debentures. The Debentures are governed by an indenture, or the Indenture, dated as of October 9, 2012 between us and The Bank of New York Mellon Trust Company, N.A., as trustee. The Debentures bear interest at a rate of 2.750% per year, payable semi-annually in arrears in cash on April 15 and October 15 of each year, and mature on October 15, 2042, unless earlier redeemed, repurchased or converted. The Debentures also have a contingent interest feature that will require us to pay additional interest based on certain thresholds and for certain events, as defined in the Indenture, beginning on October 15, 2022. Holders may convert their Debentures at their option prior to the close of business on the business day immediately preceding April 15, 2042, only under the following circumstances: (1) during any fiscal quarter commencing after the fiscal quarter ended December 31, 2012, if the last reported sale price of our common stock for at least 20 trading days during a period of 30 consecutive trading days ending on the last trading day of the preceding fiscal quarter is greater than or equal to 130% of the applicable conversion price on each applicable trading day; (2) during the five business day period after any 10 consecutive trading day period, or the measurement period, in which the trading price per $1,000 (whole dollars) principal amount of Debentures for each trading day of that measurement period was less than 98% of the product of the last reported sale price of our common stock and the applicable conversion rate on each such day; (3) if we call any or all of the Debentures for redemption, at any time prior to the close of business on the third scheduled trading day prior to the redemption date; or (4) upon the occurrence of specified corporate events, as defined in the Indenture. On and after April 15, 2042 and until the close of business on the third scheduled trading day immediately preceding the Debentures' maturity date of October 15, 2042, holders may convert their Debentures at any time irrespective of the preceding circumstances. The Debentures are redeemable at our option at any time on or after October 20, 2022, upon the occurrence of certain events, as defined in the Indenture. Upon conversion of the Debentures, we will deliver cash up to the aggregate principal amount of the Debentures converted. With respect to any conversion obligation in excess of the aggregate principal amount of the Debentures converted, we have the option to settle the excess with cash, shares of our common stock or a combination of cash and shares of common stock based on a daily conversion value, determined in accordance with the Indenture. The initial conversion rate for the Debentures will be 13.2319 shares of our common stock per $1,000 (whole dollars) of principal amount of Debentures, which represents a 25.0% conversion premium based on the closing price of $60.46 per share of our common stock on October 2, 2012 (the date the Debentures' terms were finalized) and is equivalent to an initial conversion price of approximately $75.575 per share of our common stock. The Debentures and underlying shares of our common stock have not been and will not be registered under the Securities Act of 1933, as amended, or the Securities Act, or any state securities laws and may not be offered or sold in the United States absent registration or an applicable exemption from registration requirements. The Debentures were offered and sold to qualified institutional buyers pursuant to Rule 144A under the Securities Act. We used approximately $371.0 of the net proceeds from the issuance to repurchase shares of our common stock concurrently with the offering of the Debentures, and the remaining balance was used for general corporate purposes, including but not limited to additional purchases of shares of our common stock pursuant to our share repurchase program and the repayment of short-term and/or long-term debt.
We have accounted for the Debentures in accordance with the cash conversion guidance in FASB guidance for debt with conversion and other options. As a result, the value of the embedded conversion option has been bifurcated from its debt host and recorded as a component of “additional paid-in capital” (net of deferred taxes and equity issuance costs) in our consolidated balance sheet. The following table summarizes at December 31, 2012 the related balances, conversion rate and conversion price of the Debentures:
The remaining amortization period of the unamortized debt discount as of December 31, 2012 is approximately 30 years. The unamortized discount will be amortized into interest expense using the effective interest method based on an effective interest rate of 5.130%, which represents the market interest rate for a comparable debt instrument that does not have a conversion feature. During the year ended December 31, 2012, we recognized $11.0 of interest expense related to the Debentures, of which $9.3 represented interest expense recognized at the stated interest rate of 2.750% and $1.7 represented interest expense resulting from amortization of the debt discount. Total interest paid during 2012, 2011 and 2010 was $479.1, $432.9 and $419.6, respectively.
We were in compliance with all applicable covenants under all of our outstanding debt agreements at December 31, 2012.
Future maturities of all long-term debt outstanding at December 31, 2012, including capital leases, are as follows: 2013, $1,128.0; 2014, $935.8; 2015, $624.8; 2016, $1,114.0; 2017, $1,098.9 and thereafter, $9,826.4. |

Litigation
In the ordinary course of business, we are defendants in, or parties to, a number of pending or threatened legal actions or proceedings. To the extent a plaintiff or plaintiffs in the following cases have specified in their complaint or in other court filings the amount of damages being sought, we have noted those alleged damages in the descriptions below. With respect to the cases described below, we contest liability and/or the amount of damages in each matter and believe we have meritorious defenses.
In the Los Angeles County Superior Court, we are defending a lawsuit filed by the Los Angeles City Attorney alleging the wrongful rescission of individual insurance policies and representations made concerning rescission practices and policies. The suit names WellPoint as well as Blue Cross of California, or BCC, and BC Life & Health Insurance Company, or BCL&H (which name changed to Anthem Blue Cross Life and Health Insurance Company in July 2007), both WellPoint subsidiaries. The lawsuit generally alleges unfair business practices in a purported practice of rescinding new individual members following the submission of large claims. The Los Angeles City Attorney filed an amended complaint in October 2010, adding claims of misrepresentation arising from several public statements made by the Company during 2010. The Los Angeles City Attorney is requesting two thousand five hundred dollars ($2,500) per alleged violation of the California Business and Professions Code. We intend to vigorously defend this suit; however, the ultimate outcome cannot be presently determined.
We are defending a certified class action filed as a result of the 2001 demutualization of Anthem Insurance Companies, Inc., or AICI. The lawsuit names AICI as well as Anthem, Inc., or Anthem, n/k/a WellPoint, Inc., and is captioned Ronald Gold, et al. v. Anthem, Inc. et al. AICI's 2001 Plan of Conversion, or the Plan, provided for the conversion of AICI from a mutual insurance company into a stock insurance company pursuant to Indiana law. Under the Plan, AICI distributed the fair value of the company at the time of conversion to its Eligible Statutory Members, or ESMs, in the form of cash or Anthem common stock in exchange for their membership interests in the mutual company. Plaintiffs in Gold allege that AICI distributed value to the wrong ESMs. Cross motions for summary judgment were granted in part and denied in part on July 26, 2006 with regard to the issue of sovereign immunity asserted by co-defendant, the State of Connecticut, or the State. The court also denied our motion for summary judgment as to plaintiffs' claims on January 10, 2005. The State appealed the denial of its motion to the Connecticut Supreme Court. We filed a cross-appeal on the sovereign immunity issue. On May 11, 2010, the Court reversed the judgment of the trial court denying the State's motion to dismiss the plaintiff's claims under sovereign immunity and dismissed our cross-appeal. The case was remanded to the trial court for further proceedings. Plaintiffs' motion for class certification was granted on December 15, 2011. We and the plaintiffs filed renewed cross-motions for summary judgment on January 24, 2013. We intend to vigorously defend the Gold lawsuit; however, its ultimate outcome cannot be presently determined. We settled a separate lawsuit captioned Mary E. Ormond, et al. v. Anthem, Inc., et al., also filed as a result of the 2001 demutualization of AICI. The Ormond case involves a certified class that consists of all ESMs residing in Ohio, Indiana, Kentucky or Connecticut who received cash compensation in connection with the demutualization. The class does not include employers located in Ohio and Connecticut that received cash distributions pursuant to the Plan. On June 15, 2012, plaintiffs filed an unopposed motion for preliminary approval of a $90.0 cash settlement, including any amounts to be awarded for attorneys' fees and expenses and other costs to administer the settlement. As a result, during the six months ended June 30, 2012, we recorded selling, general and administrative expense of $90.0, or $0.27 per diluted share, associated with this settlement, which was non-deductible for tax purposes. The Court granted plaintiffs' motion and entered preliminary approval of the settlement on June 18, 2012. As a result, the trial that had been set for June 18, 2012 was vacated. The cash settlement was paid on July 3, 2012 into an escrow account. A final fairness hearing on the settlement was held on October 25, 2012. On November 16, 2012, the Court granted plaintiffs' motion and entered an amended final order approving the settlement. An award of attorneys' fees was issued on November 20, 2012, together with a final judgment dismissing all of plaintiffs' claims. Two appeals of the court's final orders have been taken by objectors to the United States Court of Appeals for the Seventh Circuit. The appeals involve challenges to (i) the amount of attorneys' fees awarded to plaintiffs' counsel out of the settlement fund and (ii) the provision of the Court's order granting final approval of the settlement that requires any residual settlement funds remaining after two rounds of distributions to class members to be paid to the Eskanazi Health Foundation as a cy pres award.
We are currently a defendant in a putative class action relating to out-of-network, or OON, reimbursement of dental claims called American Dental Association v. WellPoint Health Networks, Inc. and Blue Cross of California. The lawsuit was filed in March 2002 by the American Dental Association, and three dentists who are suing on behalf of themselves and are seeking to sue on behalf of a nationwide class of all non-participating dental providers who were paid less than their actual charges for dental services provided to members of some of our affiliates' and subsidiaries' dental plans. The dentists sue as purported assignees of their patients' rights to benefits under our dental plans. The complaint alleges that we breached our contractual obligations in violation of ERISA by paying usual, customary and reasonable, or UCR, rates, rather than the dentists' actual charges, allegedly relying on undisclosed, non-existent or flawed UCR data. The plaintiffs claim, among other things, that the data failed to account for differences in geography, provider specialty, outlier (high) charges, and complexity of procedure. The complaint further alleges that we were aware that the data was inappropriate to set UCR rates and that we routinely paid OON dentists less than their actual charges, representing that our OON payments were properly determined UCR rates. The suit was pending in the United States District Court for the Southern District of Florida. On December 23, 2011, the District Court granted our motion for summary judgment and dismissed the case. The plaintiffs filed a notice of appeal with the United States Court of Appeals for the Eleventh Circuit. On October 23, 2012, the Court affirmed the entry of summary judgment in the Company's favor.
We are currently a defendant in eleven putative class actions relating to OON reimbursement that were consolidated into a single multi-district lawsuit called In re WellPoint, Inc. Out-of-Network “UCR” Rates Litigation that is pending in the United States District Court for the Central District of California. The lawsuits were filed in 2009. The plaintiffs include current and former members on behalf of a putative class of members who received OON services for which the defendants paid less than billed charges, the American Medical Association, four state medical associations, OON physicians, chiropractors, clinical psychologists, podiatrists, psychotherapists, the American Podiatric Association, California Chiropractic Association and the California Psychological Association on behalf of a putative class of all physicians and all non-physician health care providers, and an OON surgical center. In the consolidated complaint, the plaintiffs allege that the defendants violated the Racketeer Influenced and Corrupt Organizations Act, or RICO, the Sherman Antitrust Act, ERISA, federal regulations, and state law by relying on databases provided by Ingenix in determining OON reimbursement. A consolidated amended complaint was filed to add allegations in the lawsuit that OON reimbursement was calculated improperly by methodologies other than the Ingenix databases. We filed a motion to dismiss the amended consolidated complaint. The motion was granted in part and denied in part. The court gave the plaintiffs permission to replead many of those claims that were dismissed. The plaintiffs then filed a third amended consolidated complaint repleading some of the claims that had been dismissed without prejudice and adding additional statements in an attempt to bolster other claims. We filed a motion to dismiss the third amended consolidated complaint, which was granted in part and denied in part. The plaintiffs filed a fourth amended consolidated complaint on November 5, 2012. We filed a motion to dismiss most of the claims asserted in the fourth amended consolidated complaint. The plaintiffs have not yet filed a response. The OON surgical center voluntarily dismissed their claims. Fact discovery is complete. At the end of 2009, we filed a motion in the United States District Court for the Southern District of Florida, or the Florida Court, to enjoin the claims brought by the medical doctors and doctors of osteopathy and certain medical associations based on prior litigation releases, which was granted in 2011, and that court ordered the plaintiffs to dismiss their claims that are barred by the release. The plaintiffs then filed a petition for declaratory judgment asking the court to find that these claims are not barred by the releases from the prior litigation. We filed a motion to dismiss the declaratory judgment action, which was granted. The plaintiffs appealed the dismissal of the declaratory judgment to the United States Court of Appeals for the Eleventh Circuit, but the dismissal was upheld. The enjoined physicians have not yet dismissed their claims. The Florida Court found the enjoined physicians in contempt and sanctioned them on July 25, 2012. The barred physicians are paying the sanctions. We intend to vigorously defend these suits; however, their ultimate outcome cannot be presently determined.
Where available information indicates that it is probable that a loss has been incurred as of the date of the consolidated financial statements and we can reasonably estimate the amount of that loss, we accrue the estimated loss by a charge to income. In many proceedings, however, it is difficult to determine whether any loss is probable or reasonably possible. In addition, even where loss is possible or an exposure to loss exists in excess of the liability already accrued with respect to a previously identified loss contingency, it is not always possible to reasonably estimate the amount of the possible loss or range of loss.
With respect to many of the proceedings to which we are a party, we cannot provide an estimate of the possible losses, or the range of possible losses in excess of the amount, if any, accrued, for various reasons, including but not limited to some or all of the following: (i) there are novel or unsettled legal issues presented, (ii) the proceedings are in early stages, (iii) there is uncertainty as to the likelihood of a class being certified or decertified or the ultimate size and scope of the class, (iv) there is uncertainty as to the outcome of pending appeals or motions, (v) there are significant factual issues to be resolved, and/or (vi) in many cases, the plaintiffs have not specified damages in their complaint or in court filings. For those legal proceedings where a loss is probable, or reasonably possible, and for which it is possible to reasonably estimate the amount of the possible loss or range of losses, we currently believe that the range of possible losses, in excess of established reserves, for all of those proceedings is from $0 to approximately $350.0 at December 31, 2012. This estimated aggregate range of reasonably possible losses is based upon currently available information taking into account our best estimate of such losses for which such an estimate can be made.
Other Contingencies
From time to time, we and certain of our subsidiaries are parties to various legal proceedings, many of which involve claims for coverage encountered in the ordinary course of business. We, like HMOs and health insurers generally, exclude certain health care and other services from coverage under our HMO, PPO and other plans. We are, in the ordinary course of business, subject to the claims of our enrollees arising out of decisions to restrict or deny reimbursement for uncovered services. The loss of even one such claim, if it results in a significant punitive damage award, could have a material adverse effect on us. In addition, the risk of potential liability under punitive damage theories may increase significantly the difficulty of obtaining reasonable settlements of coverage claims.
In addition to the lawsuits described above, we are also involved in other pending and threatened litigation of the character incidental to our business, and are from time to time involved as a party in various governmental investigations, audits, reviews and administrative proceedings. These investigations, audits, reviews and administrative proceedings include routine and special inquiries by state insurance departments, state attorneys general, the U.S. Attorney General and subcommittees of the U.S. Congress. Such investigations, audits, reviews and administrative proceedings could result in the imposition of civil or criminal fines, penalties, other sanctions and additional rules, regulations or other restrictions on our business operations. Any liability that may result from any one of these actions, or in the aggregate, could have a material adverse effect on our consolidated financial position or results of operations.
The National Organization of Life & Health Insurance Guaranty Associations, or NOLHGA, is a voluntary organization consisting of the state life and health insurance guaranty associations located throughout the U.S. State life and health insurance guaranty associations, working together with NOLHGA, provide a safety net for their state's policyholders, ensuring that they continue to receive coverage even if their insurer is declared insolvent. We are aware that the Pennsylvania Insurance Commissioner, or Insurance Commissioner, has placed Penn Treaty Network America Insurance Company and its subsidiary American Network Insurance Company, or collectively Penn Treaty, in rehabilitation, an intermediate action before insolvency. The state court denied the Insurance Commissioner's petition for the liquidation of Penn Treaty and ordered the Commissioner to file an updated plan of rehabilitation. The Insurance Commissioner has filed a Notice of Appeal asking the Pennsylvania Supreme Court to reverse the order denying the liquidation petition. In the event rehabilitation of Penn Treaty is unsuccessful and Penn Treaty is declared insolvent and placed in liquidation, we and other insurers may be required to pay a portion of their policyholder claims through state guaranty association assessments in future periods. Given the uncertainty around whether Penn Treaty will ultimately be declared insolvent and, if so, the amount of the insolvency, the amount and timing of any associated future guaranty fund assessments and the availability and amount of any potential premium tax and other offsets, we currently cannot estimate our net exposure, if any, to this potential insolvency. We will continue to monitor the situation and may record a liability and expense in future reporting periods, which could be material to our cash flows and results of operations.
Contractual Obligations and Commitments
We are a party to an agreement with Express Scripts, Inc., or Express Scripts, to provide pharmacy benefit management, or PBM, services for our plans, excluding Amerigroup and certain self-insured members, which have exclusive agreements with different PBM services providers. The initial term of this agreement expires on December 31, 2019. Under this agreement, Express Scripts is the exclusive provider of certain specified PBM services, such as pharmacy network management, home delivery, pharmacy customer service, claims processing, rebate management, drug utilization and specialty pharmaceutical management services. Accordingly, the agreement contains certain financial and operational requirements obligating both Express Scripts and us. Express Scripts' primary obligations relate to the performance of such services and meeting certain pricing guarantees and performance standards. Our primary obligations relate to oversight, provision of data, payment for services and certain minimum volume requirements. The failure by either party to meet the respective requirements could potentially serve as a basis for financial penalties or early termination of the contract. We believe we have appropriately recognized all rights and obligations under this contract at December 31, 2012.
During the first quarter of 2010, we entered into a new agreement with International Business Machines Corporation to provide information technology infrastructure services. This new agreement supersedes certain prior agreements and also includes provisions for additional services. Our remaining commitment under this agreement at December 31, 2012 was $445.0 through March 31, 2015. We have the ability to terminate this agreement upon the occurrence of certain events, subject to early termination fees.
On March 31, 2009, we entered into an agreement with Affiliated Computer Services, Inc. to provide certain print and mailroom services that were previously performed in-house. Our remaining commitment under this agreement at December 31, 2012 was $204.3 through March 31, 2016. We have the ability to terminate this agreement upon the occurrence of certain events, subject to early termination fees.
Vulnerability from Concentrations
Financial instruments that potentially subject us to concentrations of credit risk consist primarily of cash equivalents, investment securities, premium receivables and instruments held through hedging activities. All investment securities are managed by professional investment managers within policies authorized by our Board of Directors. Such policies limit the amounts that may be invested in any one issuer and prescribe certain investee company criteria. Concentrations of credit risk with respect to premium receivables are limited due to the large number of employer groups that constitute our customer base in the geographic regions in which we conduct business. As of December 31, 2012, there were no significant concentrations of financial instruments in a single investee, industry or geographic location. |

| Capital Stock | 15. Capital Stock Stock Incentive Plans
On March 15, 2006, our Board of Directors adopted the WellPoint 2006 Incentive Compensation Plan, or the 2006 Plan, which was approved by our shareholders on May 16, 2006. On March 4, 2009, our Board of Directors approved an amendment and restatement of the 2006 Plan to increase the number of shares available by 33.0 shares, to rename the plan as the WellPoint Incentive Compensation Plan, or Incentive Plan, and to extend the term of the Incentive Plan such that no awards may be granted on or after May 20, 2019, which was approved by our shareholders on May 20, 2009.
The Incentive Plan gives authority to the Compensation Committee of the Board of Directors to make incentive awards to our non-employee directors, employees and consultants, consisting of stock options, stock, restricted stock, restricted stock units, cash-based awards, stock appreciation rights, performance shares and performance units. The Incentive Plan, as amended and restated, increases the number of available shares for issuance to 60.1 shares, subject to adjustment as set forth in the Incentive Plan.
Stock options are granted for a fixed number of shares with an exercise price at least equal to the fair value of the shares at the grant date. Stock options vest over three years in equal semi-annual installments and generally have a term of seven years from the grant date.
Certain option grants contain provisions whereby the employee continues to vest in the award subsequent to termination due to retirement. Our attribution method for newly granted awards considers all vesting and other provisions, including retirement eligibility, in determining the requisite service period over which the fair value of the awards will be recognized.
Restricted stock awards are issued at the fair value of the stock on the grant date and may also include one or more performance measures that must be met for the restricted stock award to vest. The restrictions lapse in three equal annual installments.
In connection with our acquisition of Amerigroup, we assumed certain outstanding stock options and other restricted stock awards under Amerigroup's 2009 Equity Incentive Plan, or the Amerigroup Plan. These stock options and other restricted stock awards generally retain all of the rights, terms and conditions of the Amerigroup Plan. The fair value of these awards of $19.7 was calculated as of the acquisition date and was included in the total consideration transferred for the acquisition of Amerigroup.
For the years ended December 31, 2012, 2011 and 2010, we recognized share-based compensation cost of $146.5, $134.8 and $136.0, respectively, as well as related tax benefits of $52.0, $48.6 and $45.9, respectively. A summary of stock option activity for the year ended December 31, 2012 is as follows:
The intrinsic value of options exercised during the years ended December 31, 2012, 2011 and 2010 amounted to $65.4, $115.8 and $66.9, respectively. We recognized tax benefits of $22.9, $42.9 and $25.2 in 2012, 2011 and 2010, respectively, from option exercises and disqualifying dispositions. The total fair value of shares vested during the years ended December 31, 2012, 2011 and 2010 was $222.3, $120.2 and $93.5, respectively. During the years ended December 31, 2012, 2011 and 2010 we received cash of $110.8, $245.0 and $95.3, respectively, from exercises of stock options.
A summary of the status of nonvested restricted stock activity, including restricted stock units, for the year ended December 31, 2012 is as follows:
During the year ended December 31, 2012, we granted approximately 0.8 restricted stock units under the Incentive Plan that were contingent upon us achieving specified operating gain targets for 2012. We expect to issue 0.7 restricted stock units under this performance plan. These restricted stock units have been included in the activity shown above.
As of December 31, 2012, the total remaining unrecognized compensation cost related to nonvested stock options and restricted stock amounted to $15.4 and $90.2, respectively, which will be amortized over the weighted-average remaining requisite service periods of 11 months and 19 months, respectively.
As of December 31, 2012, there were 28.9 shares of common stock available for future grants under the Incentive Plan.
Fair Value
We use a binomial lattice valuation model to estimate the fair value of all stock options granted. Expected volatility assumptions used in the binomial lattice model are based on an analysis of implied volatilities of publicly traded options on our stock and historical volatility of our stock price. The risk-free interest rate is derived from the U.S. Treasury strip rates at the time of the grant. The expected term of the options was derived from the outputs of the binomial lattice model, which incorporates post-vesting forfeiture assumptions based on an analysis of historical data. The dividend yield was based on our estimate of future dividend yields. Similar groups of employees that have dissimilar exercise behavior are considered separately for valuation purposes. We utilize the “multiple-grant” approach for recognizing compensation expense associated with each separately vesting portion of the share-based award.
The following weighted-average assumptions were used to estimate the fair values of options granted during the years ended December 31:
The following weighted-average fair values were determined for the years ending December 31:
The binomial lattice option-pricing model requires the input of highly subjective assumptions including the expected stock price volatility. Because our stock option grants have characteristics significantly different from those of traded options, and because changes in the subjective input assumptions can materially affect the fair value estimate, in our opinion, existing models do not necessarily provide a reliable single measure of the fair value of our stock option grants.
Employee Stock Purchase Plan
We have registered 14.0 shares of common stock for the Employee Stock Purchase Plan, or the Stock Purchase Plan, which was intended to provide a means to encourage and assist employees in acquiring a stock ownership interest in WellPoint. The Stock Purchase Plan was suspended effective January 1, 2011, and no shares were issued or expense recognized during 2012 or 2011. During 2010, 1.0 shares of common stock were purchased under the Stock Purchase Plan, resulting in $8.5 of related compensation cost. As of December 31, 2012, 6.1 shares were available for issuance under the Stock Purchase Plan.
Use of Capital and Stock Repurchase Program
We regularly review the appropriate use of capital, including common stock repurchases and dividends to shareholders. The declaration and payment of any dividends or repurchases of our common stock are at the discretion of our Board of Directors and depend upon our financial condition, results of operations, future liquidity needs, regulatory and capital requirements and other factors deemed relevant by our Board of Directors. Historically our common stock repurchase program, discussed below, has been our primary use of capital. Beginning in 2011, our Board of Directors established a quarterly shareholder dividend. There were no dividends paid during 2010. A summary of the cash dividend activity for the years ended December 31, 2012 and 2011 is as follows:
On February 20, 2013, the Board of Directors increased the quarterly shareholder cash dividend to $0.375 per share on the outstanding shares of our common stock. This increased quarterly dividend will be paid on March 25, 2013 to the shareholders of record as of March 8, 2013.
Under our Board of Directors' authorization, we maintain a common stock repurchase program. Repurchases may be made from time to time at prevailing market prices, subject to certain restrictions on volume, pricing and timing. The repurchases are effected from time to time in the open market, through negotiated transactions, including accelerated share repurchase agreements, and through plans designed to comply with Rule 10b5-1 under the Securities Exchange Act of 1934, as amended. Our stock repurchase program is discretionary as we are under no obligation to repurchase shares. We repurchase shares under the program when we believe it is a prudent use of capital. The excess cost of the repurchased shares over par value is charged on a pro rata basis to additional paid-in capital and retained earnings.
A summary of share repurchases for the period January 1, 2013 through February 8, 2013 (subsequent to December 31, 2012) and for the years ended December 31, 2012 and 2011 is as follows:

| Segment Information | 20. Segment Information
Our organizational structure is currently comprised of three reportable segments: Commercial, Consumer and Other. Our Commercial and Consumer segments both offer a diversified mix of managed care products, including PPOs, HMOs, traditional indemnity benefits and POS plans, as well as a variety of hybrid benefit plans, including CDHPs, hospital only and limited benefit products.
Our Commercial segment includes Local Group (including UniCare), National Accounts and certain other ancillary business operations (dental, vision, life and disability and workers' compensation). Business units in the Commercial segment offer fully-insured products and provide a broad array of managed care services to self-funded customers, including claims processing, underwriting, stop loss insurance, actuarial services, provider network access, medical cost management, disease management, wellness programs and other administrative services. Our Commercial segment also includes the operations of our 1-800 CONTACTS business.
Our Consumer segment includes Senior, State-Sponsored and Individual business. Senior business includes services such as Medicare Advantage (including private fee-for-service plans and special needs plans), Medicare Part D, and Medicare Supplement, while State-Sponsored business includes our managed care alternatives through publicly funded health care programs, including Medicaid, state Children's Health Insurance Programs and Medicaid expansion programs (including those programs managed by Amerigroup). Individual business includes individual customers under age 65 and their covered dependents.
Our Other segment includes the Comprehensive Health Solutions business unit, or CHS, that brings together our resources focused on optimizing the quality of health care, the clinical consumer experience and cost of care management. CHS includes provider relations, care and disease management, employee assistance programs, including behavioral health, radiology benefit management and analytics-driven, evidence-based personal health care guidance. Our Other segment also contains results from our Federal Government Solutions, or FGS, business. FGS business includes FEP and National Government Services, Inc., which acts as a Medicare contractor in several regions across the nation. The Other segment also includes other businesses that do not meet the quantitative thresholds for an operating segment as defined in FASB guidance, as well as intersegment sales and expense eliminations and corporate expenses not allocated to the other reportable segments.
We define operating revenues to include premium income, administrative fees and other revenues. Operating revenues are derived from premiums and fees received primarily from the sale and administration of health benefit products, as well as sales of ocular products by 1-800 CONTACTS. Operating gain is calculated as total operating revenue less benefit expense, selling, general and administrative expense and cost of products.
Through our participation in various federal government programs, we generated approximately 23.6%, 23.5% and 21.9% of our total consolidated revenues from agencies of the U.S. government for the years ended December 31, 2012, 2011, and 2010, respectively. These revenues are contained in the Consumer and Other segments. The accounting policies of the segments are consistent with those described in the summary of significant accounting policies in Note 2, “Basis of Presentation and Significant Accounting Policies,” except that certain shared administrative expenses for each segment are recognized on a pro rata allocated basis, which in aggregate approximates the consolidated expense. Any difference between the allocated expenses and actual consolidated expense is included in other expenses not allocated to reportable segments. Intersegment sales and expenses are recorded at cost and eliminated in the consolidated financial statements. We evaluate performance of the reportable segments based on operating gain or loss as defined above. We evaluate investment income, gain on sale of business, net realized gains on investments, other-than-temporary impairment losses recognized in income, interest expense, amortization expense and income taxes, and asset and liability details on a consolidated basis as these items are managed in a corporate shared service environment and are not the responsibility of segment operating management.
Financial data by reportable segment for the years ended December 31 is as follows:
The major product revenues for each of the reportable segments for the years ended December 31, are as follows:
The classification between managed care products and managed care services in the above table primarily distinguishes between the level of risk assumed. Managed care products represent insurance products where we bear the insurance risk, whereas managed care services represent product offerings where we provide claims adjudication and other administrative services to the customer, but the customer principally bears the insurance risk.
Asset and equity details by reportable segment have not been disclosed, as we do not internally report such information.

| Statutory Information [Abstract] | |
| Statutory Information | 22. Statutory Information
The majority of our insurance and HMO subsidiaries report their accounts in conformity with accounting practices prescribed or permitted by state insurance regulatory authorities, or statutory, which vary in certain respects from GAAP. However, certain of our insurance and HMO subsidiaries, including BCC, Blue Cross of California Partnership Plan, Inc., Golden West Health Plan, Inc. and CareMore Health Plan are regulated by the California Department of Managed Health Care, or DMHC, and report their accounts in conformity with GAAP (these entities are collectively referred to as the “DMHC regulated entities”). Typical differences of GAAP reporting as compared to statutory reporting are the inclusion of unrealized gains or losses relating to fixed maturity securities in shareholders' equity, recognition of all assets including those that are non-admitted for statutory purposes and recognition of all deferred tax assets without regard to statutory limits. The National Association of Insurance Commissioners, or NAIC, developed a codified version of the statutory accounting principles, designed to foster more consistency among the states for accounting guidelines and reporting.
Our insurance and HMO subsidiaries that are subject to statutory reporting are domiciled in various jurisdictions. These subsidiaries prepare statutory financial statements in accordance with accounting practices prescribed or permitted by the respective jurisdictions' insurance regulators. Prescribed statutory accounting practices are set forth in a variety of publications of the NAIC as well as state laws, regulations and general administrative rules.
Our ability to pay dividends and credit obligations is significantly dependent on receipt of dividends from our subsidiaries. The payment of dividends to us by our insurance and HMO subsidiaries without prior approval of the insurance departments of each subsidiary's domiciliary jurisdiction is limited by formula. Dividends in excess of these amounts are subject to prior approval by the respective state insurance departments or the DMHC.
Our statutory basis insurance and HMO subsidiaries are subject to risk-based capital requirements. Risk-based capital is a method developed by the NAIC to determine the minimum amount of statutory capital appropriate for an insurance company or HMO to support its overall business operations in consideration of its size and risk profile. The formula for determining the amount of risk-based capital specifies various factors, weighted based on the perceived degree of risk, which are applied to certain financial balances and financial activity. Below minimum risk-based capital requirements are classified within certain levels, each of which requires specified corrective action. Additionally, the DMHC regulated entities are subject to capital and solvency requirements as prescribed by the DMHC. As of December 31, 2012 and 2011, all of our regulated subsidiaries exceeded the minimum risk-based capital requirements and/or capital and solvency requirements of their applicable governmental regulator.
Statutory-basis capital and surplus of our insurance and HMO subsidiaries and capital and surplus of our other regulated subsidiaries, excluding the DMHC regulated entities, was $9,967.7 and $7,681.5 at December 31, 2012 and 2011, respectively. Statutory-basis net income of our insurance and HMO subsidiaries and net income of our other regulated subsidiaries, excluding the DMHC regulated entities, was $2,800.0, $2,402.5 and $2,933.8 for 2012, 2011 and 2010, respectively. GAAP equity of the DMHC regulated entities was $1,312.5 and $1,304.2 at December 31, 2012 and 2011, respectively. GAAP net income of the DMHC regulated entities was $469.7, $524.3 and $414.4 for the years ended December 31, 2012, 2011 and 2010, respectively. |

Describes the accounting practices used and the related monetary effect on statutory surplus, net income, and risk-based capital. If an insurance enterprise's risk-based capital would have triggered a regulatory event had it not used a permitted practice, that fact is disclosed in the financial statements. Permitted statutory accounting practices include practices not prescribed but allowed by the domiciliary state insurance department regulatory authority.

Basis Of Presentation And Significant Accounting Policies (Policy)

|
| Basis Of Presentation And Significant Accounting Policies [Abstract] | |
| Basis Of Presentation | Basis of Presentation: The accompanying consolidated financial statements include the accounts of WellPoint and its subsidiaries and have been prepared in conformity with U.S. generally accepted accounting principles, or GAAP. All significant intercompany accounts and transactions have been eliminated in consolidation. Certain of our subsidiaries operate outside of the United States and have functional currencies other than the U.S. dollar, or USD. We translate the assets and liabilities of those subsidiaries to USD using the exchange rate in effect at the end of the period. We translate the revenues and expenses of those subsidiaries to USD using the average exchange rates in effect during the period. The net effect of these translation adjustments is included in “Foreign currency translation adjustments” in our consolidated statements of shareholders' equity. |
| Use Of Estimates | Use of Estimates: The preparation of consolidated financial statements in conformity with GAAP requires us to make estimates and assumptions that affect the amounts reported in our consolidated financial statements and accompanying notes. Actual results could differ from those estimates. |
| Cash Equivalents | Cash Equivalents: All highly liquid investments with maturities of three months or less when purchased are classified as cash equivalents. |
| Investments | Investments: Certain Financial Accounting Standards Board, or FASB, other-than-temporary impairment, or FASB OTTI, guidance applies to fixed maturity securities and provides guidance on the recognition and presentation of other-than-temporary impairments. In addition, this FASB OTTI guidance requires disclosures related to other-than-temporary impairments. If a fixed maturity security is in an unrealized loss position and we have the intent to sell the fixed maturity security, or it is more likely than not that we will have to sell the fixed maturity security before recovery of its amortized cost basis, the decline in value is deemed to be other-than-temporary and is recorded to other-than-temporary impairment losses recognized in income in our consolidated income statements. For impaired fixed maturity securities that we do not intend to sell or it is more likely than not that we will not have to sell such securities, but we expect that we will not fully recover the amortized cost basis, the credit component of the other-than-temporary impairment is recognized in other-than-temporary impairment losses recognized in income in our consolidated income statements and the non-credit component of the other-than-temporary impairment is recognized in other comprehensive income. Furthermore, unrealized losses entirely caused by non-credit related factors related to fixed maturity securities for which we expect to fully recover the amortized cost basis continue to be recognized in accumulated other comprehensive income, or AOCI.
The credit component of an other-than-temporary impairment is determined by comparing the net present value of projected future cash flows with the amortized cost basis of the fixed maturity security. The net present value is calculated by discounting our best estimate of projected future cash flows at the effective interest rate implicit in the fixed maturity security at the date of acquisition. For mortgage-backed and asset-backed securities, cash flow estimates are based on assumptions regarding the underlying collateral including prepayment speeds, vintage, type of underlying asset, geographic concentrations, default rates, recoveries and changes in value. For all other debt securities, cash flow estimates are driven by assumptions regarding probability of default, including changes in credit ratings, and estimates regarding timing and amount of recoveries associated with a default.
The unrealized gains or losses on our current and long-term equity securities classified as available-for-sale are included in accumulated other comprehensive income as a separate component of shareholders' equity, unless the decline in value is deemed to be other-than-temporary and we do not have the intent and ability to hold such equity securities until their full cost can be recovered, in which case such equity securities are written down to fair value and the loss is charged to other-than-temporary impairment losses recognized in income. We maintain various rabbi trusts to account for the assets and liabilities under certain deferred compensation plans. Under these plans, the participants can defer certain types of compensation and elect to receive a return on the deferred amounts based on the changes in fair value of various investment options, primarily a variety of mutual funds. Rabbi trust assets are classified as trading, which are reported in other invested assets, current, in the consolidated balance sheets. We use the equity method of accounting for investments in companies in which our ownership interest enables us to influence the operating or financial decisions of the investee company. Our proportionate share of equity in net income of these unconsolidated affiliates is reported with net investment income.
For asset-backed securities included in fixed maturity securities, we recognize income using an effective yield based on anticipated prepayments and the estimated economic life of the securities. When estimates of prepayments change, the effective yield is recalculated to reflect actual payments to date and anticipated future payments. The net investment in the securities is adjusted to the amount that would have existed had the new effective yield been applied since the acquisition of the securities. Such adjustments are reported with net investment income.
Investment income is recorded when earned. All securities sold resulting in investment gains and losses are recorded on the trade date. Realized gains and losses are determined on the basis of the cost or amortized cost of the specific securities sold.
We participate in securities lending programs whereby marketable securities in our investment portfolio are transferred to independent brokers or dealers based on, among other things, their creditworthiness in exchange for cash collateral initially equal to at least 102% of the value of the securities on loan and is thereafter maintained at a minimum of 100% of the market value of the securities loaned (calculated as the ratio of initial market value of cash collateral to current market value of the securities on loan). Accordingly, the market value of the securities on loan to each borrower is monitored daily and the borrower is required to deliver additional cash collateral if the market value of the securities on loan exceeds the initial market value of cash collateral delivered. The fair value of the collateral received at the time of the transaction amounted to $564.7 and $872.5 at December 31, 2012 and 2011, respectively. The value of the cash collateral delivered represented 102% of the market value of the securities on loan at December 31, 2012 and 2011. Under the FASB guidance related to accounting for transfers and servicing of financial assets and extinguishments of liabilities, we recognize the cash collateral as an asset, which is reported as “securities lending collateral” on our consolidated balance sheets and we record a corresponding liability for the obligation to return the cash collateral to the borrower, which is reported as “securities lending payable.” The securities on loan are reported in the applicable investment category on the consolidated balance sheets. Unrealized gains or losses on securities lending collateral are included in accumulated other comprehensive income as a separate component of shareholders' equity. |
| Premium And Self-Funded Receivables | Premium and Self-Funded Receivables: Premium and self-funded receivables include the uncollected amounts from fully-insured and self-funded groups, and are reported net of an allowance for doubtful accounts of $197.1 and $183.7 at December 31, 2012 and 2011, respectively. The allowance for doubtful accounts is based on historical collection trends and our judgment regarding the ability to collect specific accounts. |
| Other Receivables | Other Receivables: Other receivables include pharmacy rebates, provider advances, claims recoveries, reinsurance, government programs, proceeds due from brokers on investment trades and other miscellaneous amounts due to us. These receivables are reported net of an allowance for uncollectible amounts of $79.0 and $149.1 at December 31, 2012 and 2011, respectively, which is based on historical collection trends and our judgment regarding the ability to collect specific amounts. |
| Income Taxes | Income Taxes: We file a consolidated income tax return. Deferred income tax assets and liabilities are recognized for temporary differences between the financial statement and tax return bases of assets and liabilities based on enacted tax rates and laws. The deferred tax benefits of the deferred tax assets are recognized to the extent realization of such benefits is more likely than not. Deferred income tax expense or benefit generally represents the net change in deferred income tax assets and liabilities during the year, excluding the impact from amounts initially recorded for business combinations, if any. Current income tax expense represents the tax consequences of revenues and expenses currently taxable or deductible on various income tax returns for the year reported.
We account for income tax contingencies in accordance with FASB guidance that contains a model to address uncertainty in tax positions and clarifies the accounting for income taxes by prescribing a minimum recognition threshold, which all income tax positions must achieve before being recognized in the financial statements. |
| Property And Equipment | Property and Equipment: Property and equipment is recorded at cost, net of accumulated depreciation. Depreciation is computed principally by the straight-line method over estimated useful lives ranging from 15 to 39 years for buildings and improvements, three to seven years for furniture and equipment, and three to five years for computer software. Leasehold improvements are depreciated over the term of the related lease. Certain costs related to the development or purchase of internal-use software are capitalized and amortized. |
| Goodwill And Other Intangible Assets | Goodwill and Other Intangible Assets: FASB guidance requires business combinations to be accounted for using the acquisition method of accounting and it also specifies the types of acquired intangible assets that are required to be recognized and reported separately from goodwill. Goodwill represents the excess of cost of acquisition over the fair value of net assets acquired. Other intangible assets represent the values assigned to subscriber bases, provider and hospital networks, Blue Cross and Blue Shield and other trademarks, licenses, non-compete and other agreements. Goodwill and other intangible assets are allocated to reportable segments based on the relative fair value of the components of the businesses acquired.
Goodwill and other intangible assets with indefinite lives are not amortized but are tested for impairment at least annually. Furthermore, goodwill and other intangible assets are allocated to reporting units for purposes of the annual impairment test. Our impairment tests require us to make assumptions and judgments regarding the estimated fair value of our reporting units, including goodwill and other intangible assets with indefinite lives. In addition, certain other intangible assets with indefinite lives, such as trademarks, are also tested separately. Fair value is calculated using a blend of a projected income and market valuation approach. The projected income approach is developed using assumptions about future revenue, expenses and net income derived from our internal planning process. Our assumed discount rate is based on our industry's weighted-average cost of capital and reflects volatility associated with the cost of equity capital. Market valuations are based on observed multiples of certain measures including membership, revenue, EBITDA (earnings before interest, taxes, depreciation and amortization) and net income as well as market capitalization analyses of WellPoint and other comparable companies. Estimated fair values developed based on our assumptions and judgments might be significantly different if other reasonable assumptions and estimates were to be used. If estimated fair values are less than the carrying values of goodwill and other intangible assets with indefinite lives in future annual impairment tests, or if significant impairment indicators are noted relative to other intangible assets subject to amortization, we may be required to record impairment losses against future income. |
| Derivative Financial Instruments | Derivative Financial Instruments: We primarily invest in the following types of derivative financial instruments: interest rate swaps, forward contracts, call options, credit default swaps, embedded derivatives, warrants and swaptions. Derivatives embedded within non-derivative instruments (such as options embedded in convertible fixed maturity securities) are bifurcated from the host instrument when the embedded derivative is not clearly and closely related to the host instrument. Our use of derivatives is limited by statutes and regulations promulgated by the various regulatory bodies to which we are subject, and by our own derivative policy. Our derivative use is generally limited to hedging purposes and we generally do not use derivative instruments for speculative purposes.
We have exposure to economic losses due to interest rate risk arising from changes in the level or volatility of interest rates. We attempt to mitigate our exposure to interest rate risk through active portfolio management, including rebalancing our existing portfolios of assets and liabilities, as well as changing the characteristics of investments to be purchased or sold in the future. In addition, derivative financial instruments are used to modify the interest rate exposure of certain liabilities or forecasted transactions. These strategies include the use of interest rate swaps and forward contracts, which are used to lock-in interest rates or to hedge (on an economic basis) interest rate risks associated with variable rate debt. We have used these types of instruments as designated hedges against specific liabilities.
All investments in derivatives are recorded as assets or liabilities at fair value. If certain correlation, hedge effectiveness and risk reduction criteria are met, a derivative may be specifically designated as a hedge of exposure to changes in fair value or cash flow. The accounting for changes in the fair value of a derivative depends on the intended use of the derivative and the nature of any hedge designation thereon. Amounts excluded from the assessment of hedge effectiveness, if any, as well as the ineffective portion of the gain or loss, are reported in results of operations immediately. If the derivative is not designated as a hedge, the gain or loss resulting from the change in the fair value of the derivative is recognized in results of operations in the period of change.
From time to time, we may also purchase derivatives to hedge (on an economic basis) our exposure to foreign currency exchange fluctuations associated with the operations of certain of our subsidiaries. We generally use futures or forward contracts for these transactions. We generally do not designate these contracts as hedges and, accordingly, the changes in fair value of these derivatives are recognized in income immediately.
Credit exposure associated with non-performance by the counterparties to derivative instruments is generally limited to the uncollateralized fair value of the asset related to instruments recognized in the consolidated balance sheets. We attempt to mitigate the risk of non-performance by selecting counterparties with high credit ratings and monitoring their creditworthiness and by diversifying derivatives among multiple counterparties. At December 31, 2012, we believe there were no material concentrations of credit risk with any individual counterparty.
Certain of our derivative agreements contain credit support provisions that require us to post collateral if there are declines in the derivative fair value or our credit rating. |
| Retirement Benefits | Retirement Benefits: We recognize the funded status of pension and other postretirement benefit plans on the consolidated balance sheets based on fiscal-year-end measurements of plan assets and benefit obligations. Prepaid pension benefits represent prepaid costs related to defined benefit pension plans and are reported with other noncurrent assets. Postretirement benefits represent outstanding obligations for retiree medical, life, vision and dental benefits. Liabilities for pension and other postretirement benefits are reported with current and noncurrent liabilities based on the amount by which the actuarial present value of benefits payable in the next twelve months included in the benefit obligation exceeds the fair value of plan assets. |
| Medical Claims Payable | Medical Claims Payable: Liabilities for medical claims payable include estimated provisions for incurred but not paid claims on an undiscounted basis, as well as estimated provisions for expenses related to the processing of claims. Incurred but not paid claims include (1) an estimate for claims that are incurred but not reported, as well as claims reported to us but not yet processed through our systems; and (2) claims reported to us and processed through our systems but not yet paid.
Liabilities for both claims incurred but not reported and reported but not yet processed through our systems are determined in aggregate by employing actuarial methods that are commonly used by health insurance actuaries and meet Actuarial Standards of Practice. Actuarial Standards of Practice require that the claim liabilities be appropriate under moderately adverse circumstances. We determine the amount of the liability for incurred but not paid claims by following a detailed actuarial process that entails using both historical claim payment patterns as well as emerging medical cost trends to project our best estimate of claim liabilities.
We regularly review and set assumptions regarding cost trends and utilization when initially establishing claim liabilities. We continually monitor and adjust the claims liability and benefit expense based on subsequent paid claims activity. If our assumptions regarding cost trends and utilization are significantly different than actual results, our income statement and financial position could be impacted in future periods.
Premium deficiencies are recognized when it is probable that expected claims and administrative expenses will exceed future premiums on existing medical insurance contracts without consideration of investment income. Determination of premium deficiencies for longer duration life and disability contracts includes consideration of investment income. For purposes of premium deficiencies, contracts are deemed to be either short or long duration and are grouped in a manner consistent with our method of acquiring, servicing and measuring the profitability of such contracts. Once established, premium deficiencies are released commensurate with actual claims experience over the remaining life of the contract. No premium deficiencies were established at December 31, 2012 or 2011. |
| Reserves For Future Policy Benefits | Reserves for Future Policy Benefits: Reserves for future policy benefits include liabilities for life and long-term disability insurance policy benefits based upon interest, mortality and morbidity assumptions from published actuarial tables, modified based upon our experience. Future policy benefits also include liabilities for insurance policies for which some of the premiums received in earlier years are intended to pay anticipated benefits to be incurred in future years. Future policy benefits are continually monitored and reviewed, and when reserves are adjusted, differences are reflected in benefit expense. The current portion of reserves for future policy benefits relates to the portion of such reserves that we expect to pay within one year. We believe that our liabilities for future policy benefits, along with future premiums received are adequate to satisfy our ultimate benefit liability; however, these estimates are inherently subject to a number of variable circumstances. Consequently, the actual results could differ materially from the amounts recorded in our consolidated financial statements. |
| Other Policyholder Liabilities | Other Policyholder Liabilities: Other policyholder liabilities include rate stabilization reserves associated with retrospectively rated insurance contracts and certain case-specific reserves as well as liabilities for minimum medical loss ratio, or MLR, rebates. Rate stabilization reserves represent accumulated premiums that exceed what customers owe us based on actual claim experience. The timing of payment of these retrospectively rated refunds is based on the contractual terms with the customers and can vary from period to period based on the specific contractual requirements.
Effective beginning in 2011, we are required to meet certain minimum MLR thresholds prescribed by the Patient Protection and Affordable Care Act and related Health Care and Education Reconciliation Act of 2010, or collectively, Health Care Reform. If we do not meet or exceed the minimum MLR thresholds specified by Health Care Reform, we are required to pay rebates to certain customers. Minimum MLR rebates are calculated by applicable line of business (large group, small group and individual) and legal entity in accordance with regulations issued by the Department of Health and Human Services, or HHS. Such calculations are made using estimated calendar year medical loss expense and premiums, as defined by HHS.
We follow HHS guidelines for determining the types of expenses that may be included in our minimum MLR rebate calculations, which may differ from benefit expense and premiums as reported in our consolidated financial statements prepared in conformity with GAAP. Certain amounts reported as expense in our GAAP basis consolidated financial statements may be reported as a reduction of premiums in accordance with HHS regulations. For example, certain federal and state income taxes and assessments recorded as income tax expense or general and administrative expense, as appropriate, in our consolidated GAAP financial statements are allowed to be included as a reduction of premium revenue in HHS' calculation of minimum MLR. In addition, profit amounts included in our payments to third party administrative service providers are recorded as benefit expense in our consolidated GAAP financial statements while HHS does not allow for the inclusion of these expenses within the medical loss expense for purposes of calculating minimum MLR. |
| Revenue Recognition | Revenue Recognition: Premiums for fully-insured contracts are recognized as revenue over the period insurance coverage is provided, net of amounts recognized for minimum MLR rebates, if applicable. Minimum MLR rebates are calculated in accordance with regulations issued by HHS. Premiums applicable to the unexpired contractual coverage periods are reflected in the accompanying consolidated balance sheets as unearned income. Premiums include revenue from retrospectively rated contracts where revenue is based on the estimated ultimate loss experience of the contract. Premium revenue includes an adjustment for retrospectively rated refunds based on an estimate of incurred claims. Premium rates for certain lines of business are subject to approval by the Department of Insurance of each respective state.
Administrative fees include revenue from certain group contracts that provide for the group to be at risk for all, or with supplemental insurance arrangements, a portion of their claims experience. We charge these self-funded groups an administrative fee, which is based on the number of members in a group or the group's claim experience. In addition, administrative fees include amounts received for the administration of Medicare or certain other government programs. Under our self-funded arrangements, revenue is recognized as administrative services are performed. All benefit payments under these programs are excluded from benefit expense.
Other revenue primarily includes ocular product sales by 1-800 CONTACTS, which are recognized as revenue when the products are shipped. For additional information about 1-800 CONTACTS, see Note 3, “Business Combinations.” |
| Share-Based Compensation | Share-Based Compensation: Our current compensation philosophy provides for share-based compensation, including stock options and restricted stock awards. Stock options are granted for a fixed number of shares with an exercise price at least equal to the fair value of the shares at the date of the grant. Restricted stock awards are issued at the fair value of the stock on the grant date. During 2010, we also offered an employee stock purchase plan. The employee stock purchase plan, which was suspended effective January 1, 2011, allowed for a purchase price per share which was 85% of the fair value of a share of common stock on the last trading day of the plan quarter. All share-based payments to employees, including grants of employee stock options and discounts associated with employee stock purchases, are recognized as compensation expense in the income statement based on their fair values. Additionally, excess tax benefits, which result from actual tax benefits exceeding deferred tax benefits previously recognized based on grant date fair value, are recognized as additional paid-in-capital and are reclassified from operating cash flows to financing cash flows in the consolidated statements of cash flows. Our share-based employee compensation plans and assumptions are described in Note 15, “Capital Stock.” |
| Advertising Costs | Advertising costs: We use print, broadcast and other advertising to promote our products and to develop our corporate image. The cost of advertising for product promotion is expensed as incurred while advertising associated with corporate image is expensed when first aired. Total advertising expense was $299.2, $287.8 and $226.1 for the years ended December 31, 2012, 2011 and 2010, respectively. |
| Earnings Per Share | Earnings per Share: Earnings per share amounts, on a basic and diluted basis, have been calculated based upon the weighted-average common shares outstanding for the period.
Basic earnings per share excludes dilution and is computed by dividing income available to common shareholders by the weighted-average number of common shares outstanding for the period. Diluted earnings per share includes the dilutive effect of stock options and restricted stock, using the treasury stock method. The treasury stock method assumes exercise of stock options and vesting of restricted stock, with the assumed proceeds used to purchase common stock at the average market price for the period. The difference between the number of shares assumed issued and number of shares assumed purchased represents the dilutive shares. |
| New Accounting Pronouncements | New Accounting Pronouncements: In June 2011, the FASB issued Accounting Standards Update, or ASU, 2011-05, Comprehensive Income (Topic 220): Presentation of Comprehensive Income, or ASU 2011-05. ASU 2011-05 supersedes certain portions of Accounting Standards Codification Topic 220, Comprehensive Income, or ASC 220, and requires increased prominence of the presentation of other comprehensive income in financial statements. ASU 2011-05 requires entities to present net income and the components of other comprehensive income in either a single continuous financial statement or in two separate but consecutive financial statements. ASU 2011-05 eliminates the option in ASC 220 to present the components of other comprehensive income in the statement of changes in equity. Most of the presentation requirements of ASU 2011-05 became effective for us on a retrospective basis beginning January 1, 2012. However, certain presentation requirements of ASU 2011-05 were deferred by the FASB's December 2011 issuance of ASU 2011-12, Deferral of the Effective Date for Amendments to the Presentation of Reclassifications of Items Out of Accumulated Other Comprehensive Income in Accounting Standards Update No. 2011-05. We elected to present the components of comprehensive income in two separate but consecutive financial statements, which is illustrated in the “Consolidated Statements of Income” and the “Consolidated Statements of Comprehensive Income.” In May 2011, the FASB issued ASU 2011-04, Fair Value Measurement (Topic 820): Amendments to Achieve Common Fair Value Measurement and Disclosure Requirements in U.S. GAAP and IFRSs, or ASU 2011-04. ASU 2011-04 amends ASC Topic 820, Fair Value Measurement, to provide guidance on how fair value measurement should be applied where existing GAAP already requires or permits fair value measurements. In addition, ASU 2011-04 requires expanded disclosures regarding fair value measurements. The adoption of ASU 2011-04 on January 1, 2012 did not have a material impact on our consolidated financial position, results of operations or cash flows. However, we have added certain disclosures related to fair value measurements in Note 7, “Fair Value.”
There were no other new accounting pronouncements that were issued or became effective during the year ended December 31, 2012 that had, or are expected to have, a material impact on our financial position, results of operations or financial statement disclosures. |
| Reclassifications | Reclassifications: As discussed above within the “Other Policyholder Liabilities” section of this Note 2, “Basis of Presentation and Significant Accounting Policies,” Health Care Reform requires that certain lines of business meet specified minimum MLR thresholds. If those thresholds are not met or exceeded, we are required to pay minimum MLR rebates. For purposes of determining MLR rebates, HHS has defined the types of costs that should be included in the minimum MLR rebate calculation. HHS' definition of costs varied from our prior benefit expense classification under GAAP. Where appropriate, we adopted HHS' classification of costs effective January 1, 2011 to further align our GAAP basis benefit expense to that used in the calculation for determining MLR rebates under HHS guidance. However, certain components of the MLR computation as defined by HHS cannot be classified consistently under GAAP. Accordingly, benefit expense ratios shown in our GAAP basis presentation are different than the MLRs used to calculate rebates under HHS guidance. Prior period amounts were not reclassified due to immateriality.
Certain other prior year amounts have been reclassified to conform to the current year presentation. |

This element represents the portion of the balance sheet assertion valued at fair value by the entity whether such amount is presented as a separate caption or as a parenthetical disclosure. Additionally, this element may be used in connection with the fair value disclosures required in the footnote disclosures to the financial statements. The element may be used in both the balance sheet and disclosure in the same submission. This item represents Available-for-sale Securities which consist of all investments in certain debt and equity securities neither classified as trading or held-to-maturity securities. A debt security represents a creditor relationship with an enterprise. Debt securities include, among other items, US Treasury securities, US government securities, municipal securities, corporate bonds, convertible debt, commercial paper, and all securitized debt instruments. An equity security represents an ownership interest in an enterprise or the right to acquire or dispose of an ownership interest in an enterprise at fixed or determinable prices. Equity securities include, among other things, common stock, certain preferred stock, warrant rights, call options, and put options, but do not include convertible debt. An entity may opt to provide the reader with additional narrative text to better understand the nature of investments in debt and equity securities which are categorized as Available-for-sale.

This element represents the portion of the balance sheet assertion valued at fair value by the entity whether such amount is presented as a separate caption or as a parenthetical disclosure. Additionally, this element may be used in connection with the fair value disclosures required in the footnote disclosures to the financial statements. The element may be used in both the balance sheet and disclosure in the same submission. This item includes currency on hand as well as demand deposits with banks or financial institutions. It also includes other kinds of accounts that have the general characteristics of demand deposits in that the Company may deposit additional funds at any time and also effectively may withdraw funds at any time without prior notice or penalty. Cash equivalents, excluding items classified as marketable securities, include short-term, highly liquid investments that are both readily convertible to known amounts of cash, and so near their maturity that they present minimal risk of changes in value because of changes in interest rates. Generally, only investments with original maturities of three months or less qualify under that definition. Original maturity means original maturity to the entity holding the investment. For example, both a three-month US Treasury bill and a three-year Treasury note purchased three months from maturity qualify as cash equivalents. However, a Treasury note purchased three years ago does not become a cash equivalent when its remaining maturity is three months. Reference 1: http://www.xbrl.org/2003/role/presentationRef
