Notes to the Condensed Consolidated Financial Statements

(Unaudited)

1. Basis of Presentation

UnitedHealth Group Incorporated (individually and together with its subsidiaries, "UnitedHealth Group" and "the Company") is a diversified health and well-being company dedicated to helping people live healthier lives and making the health system work better for everyone. Through its diversified family of businesses, the Company leverages core competencies in advanced, enabling technology; health care data, information and intelligence; and clinical care management and coordination to help meet the demands of the health system. The Company offers a broad spectrum of products and services through two distinct platforms: UnitedHealthcare, which provides health care coverage and benefits services; and Optum, which provides pharmacy care services and information and technology-enabled health services.

The Company has prepared the Condensed Consolidated Financial Statements according to U.S. Generally Accepted Accounting Principles (GAAP) and has included the accounts of UnitedHealth Group and its subsidiaries. The year-end condensed consolidated balance sheet was derived from audited financial statements, but does not include all disclosures required by GAAP. In accordance with the rules and regulations of the U.S. Securities and Exchange Commission (SEC), the Company has omitted certain footnote disclosures that would substantially duplicate the disclosures contained in its annual audited Consolidated Financial Statements. Therefore, these Condensed Consolidated Financial Statements should be read together with the Consolidated Financial Statements and the Notes included in Part II, Item 8, "Financial Statements" of the Company's Annual Report on Form 10-K for the year ended December 31, 2015 as filed with the SEC ( 2015 10-K). The accompanying Condensed Consolidated Financial Statements include all normal recurring adjustments necessary to present the interim financial statements fairly.

Use of Estimates

These Consolidated Financial Statements include certain amounts based on the Company's best estimates and judgments. The Company's most significant estimates relate to estimates and judgments for medical costs payable and revenues, valuation and impairment analysis of goodwill and other intangible assets and valuations of certain investments. Certain of these estimates require the application of complex assumptions and judgments, often because they involve matters that are inherently uncertain and will likely change in subsequent periods. The impact of any change in estimates is included in earnings in the period in which the estimate is adjusted.

The accounting policies disclosed in Note 2 of Notes to the Consolidated Financial Statements in Part II, Item 8, "Financial Statements" in the 2015 10-K remain unchanged.

Reclassification

During the fourth quarter of 2015, the Company aligned its accounting policy to conform the presentation of certain pharmacy fulfillment costs related to an acquired OptumRx business. These costs are now included in medical costs and cost of products sold, whereas they were previously included in operating costs. Prior periods have been reclassified to conform to the current period presentation. The reclassification increased medical expenses by $101 million , decreased operating costs by $115 million and increased cost of products sold by $14 million for the three months ended March 31, 2015. The reclassification had no impact on total operating costs, earnings from operations, net earnings, earnings per share or total equity.

Recently Issued Accounting Standards

In February 2016, the Financial Accounting Standards Board (FASB) issued Accounting Standard Update (ASU) No. 2016-02, "Leases (Topic 842)" (ASU 2016-02). Under ASU 2016-02, an entity will be required to recognize assets and liabilities for the rights and obligations created by leases on the entity's balance sheet for both finance and operating leases. For leases with a term of 12 months or less, an entity can elect to not recognize lease assets and lease liabilities and expense the lease over a straight-line basis for the term of the lease. ASU 2016-02 will require new disclosures that depict the amount, timing, and uncertainty of cash flows pertaining to an entity's leases. Companies are required to adopt the new standard using a modified retrospective approach for annual and interim periods beginning after December 15, 2018. Early adoption of ASU 2016-02 is permitted. The Company is currently evaluating the effect of the new leasing guidance.

In January 2016, the FASB issued ASU 2016-01, "Financial Instruments - Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities" (ASU 2016-01). The new guidance changes the current accounting related to (i) the classification and measurement of certain equity investments, (ii) the presentation of changes in the fair value of financial liabilities measured under the fair value option that are due to instrument-specific credit risk, and (iii) certain disclosures associated with the fair value of financial instruments. Most notably, ASU 2016-01 requires that equity investments, with certain exemptions, be measured at fair value with changes in fair value recognized in net income as opposed to other

Table of Contents

comprehensive income. The new guidance is effective for annual and interim reporting periods beginning after December 15, 2017. The Company is currently evaluating the effect of the new financial instruments guidance.

In May 2014, the FASB issued ASU No. 2014-09, "Revenue from Contracts with Customers (Topic 606)" (ASU 2014-09) as modified by ASU No. 2015-14, "Revenue from Contracts with Customers (Topic 606): Deferral of the Effective Date," ASU 2016-08, "Revenue from Contracts with Customers (Topic 606): Principal versus Agent Considerations (Reporting Revenue Gross versus Net)" and ASU No. 2016-10, "Revenue from Contracts with Customers (Topic 606): Identifying Performance Obligations and Licensing." ASU 2014-09 will supersede existing revenue recognition standards with a single model unless those contracts are within the scope of other standards (e.g., an insurance entity's insurance contracts). The revenue recognition principle in ASU 2014-09 is that an entity should recognize revenue to depict the transfer of goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. In addition, new and enhanced disclosures will be required. Companies may adopt the new standard either using the full retrospective approach, a modified retrospective approach with practical expedients, or a cumulative effect upon adoption approach. ASU 2014-09 is effective for annual and interim reporting periods beginning after December 15, 2017. Early adoption at the original effective date, interim and annual periods beginning after December 15, 2016, will be permitted. The Company is currently evaluating the effect of the new revenue recognition guidance.

Recently Adopted Accounting Standards

In March 2016, the FASB issued ASU No. 2016-09, "Compensation-Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting" (ASU 2016-09). ASU 2016-09 modifies several aspects of the accounting for share-based payment awards, including income tax consequences, and classification on the statement of cash flows. The Company early adopted ASU 2016-09 in the first quarter of 2016. The provisions of ASU 2016-09 related to the timing of when excess tax benefits are recognized, minimum statutory withholding requirements and forfeitures were adopted using a modified retrospective transition method by means of a cumulative-effect adjustment to equity as of January 1, 2016. The provisions of ASU 2016-09 related to the recognition of excess tax benefits in the income statement and classification in the statement of cash flows were adopted prospectively and the prior periods were not retrospectively adjusted. The adoption of ASU 2016-09 did not materially impact the Company's consolidated financial position, results of operations, equity or cash flows.

In November 2015, the FASB issued ASU No. 2015-17, "Income Taxes (Topic 740): Balance Sheet Classification of Deferred Taxes" (ASU 2015-17). ASU 2015-17 requires entities to present deferred tax assets and deferred tax liabilities as noncurrent on the balance sheet. Prior to the issuance of ASU 2015-17, deferred taxes were required to be presented as a net current asset or liability and a net noncurrent asset or liability. The Company adopted ASU 2015-17 on a prospective basis in the first quarter of 2016 and the prior period was not retrospectively adjusted. The adoption of ASU 2015-17 did not impact the Company's consolidated financial position, results of operations, equity or cash flows.

In April 2015, the FASB issued ASU No. 2015-03, "Interest-Imputation of Interest (Subtopic 835-30): Simplifying the Presentation of Debt Issuance Costs" (ASU 2015-03). ASU 2015-03 requires debt issuance costs to be presented as a reduction of the carrying amount of the related debt liability. Prior to the issuance of ASU 2015-03, debt issuance costs were required to be presented as an asset in the balance sheet. The Company adopted ASU 2015-03 on a retrospective basis, as required, in the first quarter of 2016. The Company reclassified $129 million in debt issuance costs that were recorded in other assets on the Consolidated Balance Sheet as of December 31, 2015 to long-term debt, less current maturities.

The Company has determined that there have been no other recently adopted or issued accounting standards that had, or will have, a material impact on its Condensed Consolidated Financial Statements.

The Company's unrealized losses from all securities as of March 31, 2016 were generated from approximately 5,000 positions out of a total of 26,000 positions. The Company believes that it will collect the principal and interest due on its debt securities that have an amortized cost in excess of fair value. The unrealized losses were primarily caused by interest rate increases and not by unfavorable changes in the credit quality associated with these securities. As of March 31, 2016 , the Company did not have the intent to sell any of the securities in an unrealized loss position. Therefore, the Company believes these losses to be temporary.

Net realized gains reclassified out of accumulated other comprehensive income were from the following sources:

3. Fair Value

Certain assets and liabilities are measured at fair value in the Condensed Consolidated Financial Statements or have fair values disclosed in the Notes to the Condensed Consolidated Financial Statements. These assets and liabilities are classified into one of three levels of a hierarchy defined by GAAP.

Table of Contents

For a description of the methods and assumptions that are used to estimate the fair value and determine the fair value hierarchy classification of each class of financial instrument, see Note 5 of Notes to the Consolidated Financial Statements in Part II, Item 8, "Financial Statements" in the 2015 10-K.

The Company elected to measure the entirety of the Supplemental Health Insurance Program (AARP Program) assets under management at fair value pursuant to the fair value option. See Note 2 of Notes to the Consolidated Financial Statements in Part II, Item 8, "Financial Statements" in the 2015 10-K for further detail on the AARP Program.

The following table presents a summary of fair value measurements by level and carrying values for items measured at fair value on a recurring basis in the Condensed Consolidated Balance Sheets, excluding assets and liabilities related to the AARP Program:

Commercial Paper and Bank Credit Facilities

Commercial paper consists of short-duration, senior unsecured debt privately placed on a discount basis through broker-dealers. As of March 31, 2016 , the Company's outstanding commercial paper had a weighted-average annual interest rate of 0.7% .

The Company has $3.0 billion five-year, $2.0 billion three-year and $1.0 billion 364-day revolving bank credit facilities with 23 banks, which mature in December 2020 , December 2018 , and November 2016 , respectively. These facilities provide liquidity support for the Company's commercial paper program and are available for general corporate purposes. As of March 31, 2016 , no amounts had been drawn on any of the bank credit facilities. The annual interest rates, which are variable based on term, are calculated based on the London Interbank Offered Rate (LIBOR) plus a credit spread based on the Company's senior unsecured credit ratings. If amounts had been drawn on the bank credit facilities as of March 31, 2016 , annual interest rates would have ranged from 1.2% to 1.7% .

Debt Covenants

The Company's bank credit facilities contain various covenants, including covenants requiring the Company to maintain a defined debt to debt-plus-shareholders' equity ratio of not more than 55% . The Company was in compliance with its debt covenants as of March 31, 2016 .

8. Commitments and Contingencies

Legal Matters

Because of the nature of its businesses, the Company is frequently made party to a variety of legal actions and regulatory inquiries, including class actions and suits brought by members, care providers, consumer advocacy organizations, customers and regulators, relating to the Company's businesses, including management and administration of health benefit plans and other services. These matters include medical malpractice, employment, intellectual property, antitrust, privacy and contract claims and claims related to health care benefits coverage and other business practices.

The Company records liabilities for its estimates of probable costs resulting from these matters where appropriate. Estimates of costs resulting from legal and regulatory matters involving the Company are inherently difficult to predict, particularly where the matters: involve indeterminate claims for monetary damages or may involve fines, penalties or punitive damages; present novel legal theories or represent a shift in regulatory policy; involve a large number of claimants or regulatory bodies; are in the early stages of the proceedings; or could result in a change in business practices. Accordingly, the Company is often unable to estimate the losses or ranges of losses for those matters where there is a reasonable possibility or it is probable that a loss may be incurred.

Litigation Matters

California Claims Processing Matter. On January 25, 2008, the California Department of Insurance (CDI) issued an Order to Show Cause to PacifiCare Life and Health Insurance Company, a subsidiary of the Company, alleging violations of certain insurance statutes and regulations related to an alleged failure to include certain language in standard claims correspondence, timeliness and accuracy of claims processing, interest payments, care provider contract implementation, care provider dispute resolution and other related matters. Although the Company believes that CDI had never before issued a fine in excess of $8 million , CDI advocated a fine of approximately $325 million in this matter. The matter was the subject of an administrative hearing before a California administrative law judge beginning in December 2009, and in August 2013, the administrative law judge issued a nonbinding proposed decision recommending a fine of $11.5 million . The California Insurance Commissioner rejected the administrative law judge's recommendation and on June 9, 2014, issued his own decision imposing a fine of approximately $174 million . On July 10, 2014, the Company filed a lawsuit in California state court challenging the Commissioner's decision. On September 8, 2015, in the first phase of that lawsuit, the California state court issued an order invalidating certain of the regulations the Commissioner had relied upon in issuing his decision and penalty. The Company cannot reasonably estimate the range of loss, if any, that may result from this matter given the procedural status of the dispute, the wide range of possible outcomes, the legal issues presented (including the legal basis for the majority of the alleged violations), the inherent difficulty in predicting a regulatory fine in the event of a remand, and the various remedies and levels of judicial review that remain available to the Company.

Government Investigations, Audits and Reviews

The Company has been involved or is currently involved in various governmental investigations, audits and reviews. These include routine, regular and special investigations, audits and reviews by the Centers for Medicare and Medicaid Services (CMS), state insurance and health and welfare departments, the Brazilian national regulatory agency for private health insurance and plans (the Agência Nacional de Saúde Suplementar), state attorneys general, the Office of the Inspector General, the Office of Personnel Management, the Office of Civil Rights, the Government Accountability Office, the Federal Trade

Table of Contents

Commission, U.S. Congressional committees, the U.S. Department of Justice, the SEC, the Internal Revenue Service, the U.S. Drug Enforcement Administration, the Brazilian federal revenue service (the Secretaria da Receita Federal), the U.S. Department of Labor, the Federal Deposit Insurance Corporation, the Defense Contract Audit Agency and other governmental authorities. Certain of the Company's businesses have been reviewed or are currently under review, including for, among other matters, compliance with coding and other requirements under the Medicare risk-adjustment model. The Company has produced documents, information and witnesses to the Department of Justice in cooperation with a current review of the Company's risk-adjustment processes, including the Company's patient chart review and related programs. CMS has selected certain of the Company's local plans for risk adjustment data validation (RADV) audits to validate the coding practices of and supporting documentation maintained by health care providers and such audits may result in retrospective adjustments to payments made to the Company's health plans.

The Company cannot reasonably estimate the range of loss, if any, that may result from any material government investigations, audits and reviews in which it is currently involved given the status of the reviews, the wide range of possible outcomes and inherent difficulty in predicting regulatory action, fines and penalties, if any, the Company's legal and factual defenses and the various remedies and levels of judicial review available to the Company in the event of an adverse finding.

Guaranty Fund Assessments

Under state guaranty association laws, certain insurance companies can be assessed (up to prescribed limits) for certain obligations to the policyholders and claimants of impaired or insolvent insurance companies (including state health insurance cooperatives) that write the same line or similar lines of business. In 2009, the Pennsylvania Insurance Commissioner placed long term care insurer Penn Treaty Network America Insurance Company and its subsidiary (Penn Treaty), neither of which is affiliated with the Company, in rehabilitation and petitioned a state court for approval to liquidate Penn Treaty. In 2012, the court denied the liquidation petition and ordered the Insurance Commissioner to submit a rehabilitation plan. The court held a hearing in July 2015 to begin its consideration of the latest proposed rehabilitation plan. The hearing is scheduled to continue in 2016.

If the current proposed rehabilitation plan, which contemplates the partial liquidation of Penn Treaty, is approved by the court, the Company's insurance entities and other insurers may be required to pay a portion of Penn Treaty's policyholder claims through state guaranty association assessments. The Company continues to vigorously challenge the proposed rehabilitation plan. The Company is currently unable to estimate losses or ranges of losses because the Company cannot predict when or to what extent Penn Treaty will ultimately be liquidated, the amount of the insolvency, the amount and timing of any associated guaranty fund assessments or the availability and amount of any premium tax and other potential offsets.

EXECUTIVE OVERVIEW

General

UnitedHealth Group is a diversified health and well-being company dedicated to helping people live healthier lives and making the health system work better for everyone. Through our diversified family of businesses, we leverage core competencies in advanced, enabling technology; health care data; information and intelligence; and clinical care management and coordination to help meet the demands of the health system. We offer a broad spectrum of products and services through two distinct platforms: UnitedHealthcare, which provides health care coverage and benefits services; and Optum, which provides information and technology-enabled health services.

Table of Contents

Further information on our business is included in Part I, Item 1, "Business" and Part II, Item 7, "Management's Discussion and Analysis of Financial Condition and Results of Operations" in our 2015 10-K and additional information on our segments can be found in this Item 2 and in Note 9 of Notes to the Condensed Consolidated Financial Statements in Part I, Item 1 of this report.

Business Trends

Our businesses participate in the United States, Brazilian and certain other international health economies. In the United States, health care spending has grown consistently for many years and comprises approximately 18% of gross domestic product. We expect overall spending on health care to continue to grow in the future due to inflation, medical technology and pharmaceutical advancement, regulatory requirements, demographic trends in the population and national interest in health and well-being. The rate of market growth may be affected by a variety of factors, including macro-economic conditions and regulatory changes, which have impacted and could further impact our results of operations.

Pricing Trends . To price our health care benefit products, we start with our view of expected future costs. We frequently evaluate and adjust our approach in each of the local markets we serve, considering all relevant factors, such as product positioning, price competitiveness and environmental, competitive, legislative and regulatory aspects. Our review of regulatory considerations involves a focus on minimum loss ratio (MLR) thresholds and the risk adjustment and reinsurance provisions that impact the small group and individual markets. We will continue seeking to balance growth and profitability across all of these dimensions.

We continue to expect broad-based competition in commercial products and pressure from government funding. The intensity of commercial pricing competition depends on local market conditions and competitive dynamics. Annual commercial premium rate increases are subject to federal and state review and approval procedures. In addition, a provision in the 2016 Federal Budget imposes a one year moratorium for payment of the 2017 Health Insurance Industry Tax. For policies that include a portion of 2017 coverage periods, our premiums will reflect the impact of the moratorium. Medicare Advantage funding continues to be pressured, as discussed below in "Regulatory Trends and Uncertainties." We expect continued Medicaid revenue growth due to anticipated increases in the number of people we serve; we also believe that the reimbursement rate environment creates the risk of downward pressure on Medicaid net margin percentages.

Medical Cost Trends. Our medical cost trends primarily relate to changes in unit costs, health system utilization and prescription drug costs. We endeavor to mitigate those increases with medical management. Our 2016 management activities include managing costs across all health care categories, including specialty pharmacy spending, as new therapies are introduced at high costs and older drugs experience price increases.

Regulatory Trends and Uncertainties

Following is a summary of management's view of the trends and uncertainties related to some of the key provisions of the Patient Protection and Affordable Care Act and a reconciliation measure, the Health Care and Education Reconciliation Act of 2010 (together, Health Reform Legislation) and other regulatory items. For additional information about Health Reform Legislation and regulatory trends and uncertainties, see Part I, Item 1, "Business - Government Regulation," Item 1A, "Risk Factors," and Part II, Item 7, "Management's Discussion and Analysis of Financial Condition and Results of Operations" in our 2015 10-K.

Medicare Advantage Rates and Minimum Loss Ratios. Final 2017 Medicare Advantage rates resulted in an increase in industry base rates of approximately 0.85%, well short of the industry forward medical cost trend of 3%, which creates continued pressure in the Medicare Advantage program. The impact of these cuts to our Medicare Advantage revenues is partially mitigated by reductions in provider reimbursements for those care providers with rates indexed to Medicare Advantage revenues or Medicare fee-for-service reimbursement rates. These factors can affect our plan benefit designs, pricing, growth prospects and earnings expectations for our Medicare Advantage plans.

As provided in the Affordable Care Act, our Medicare Advantage rates are currently enhanced by CMS quality bonuses in certain counties based on our local plans' star ratings. The level of star ratings from CMS, based upon specified clinical and operational performance standards, will impact future quality bonuses. In addition, star ratings affect the amount of savings a plan can use to offer supplemental benefits, which ultimately may affect the plan's membership and revenue. For the 2016 payment year, approximately 57% of our Medicare Advantage members are in plans rated four stars or higher. We expect that at least 63% of our Medicare Advantage members will be in plans rated four stars or higher for payment year 2017. We continue to dedicate substantial resources to advance our quality scores and star ratings to strengthen our local market programs and further improve our performance.

Health Insurance Industry Tax and Premium Stabilization Programs. The industry-wide amount of the annual tax is $11.3 billion in 2016 and we expect to pay our proportionate share of $1.8 billion in September 2016. Health Reform Legislation also

Table of Contents

includes three programs designed to stabilize the health insurance markets. These programs encompass: a temporary reinsurance program; a temporary risk corridors program; and a permanent risk adjustment program.

For details on the Health Insurance Industry Tax and Premium Stabilization Programs, see Note 2 of Notes to the Consolidated Financial Statements included in Part 2, Item 8, "Financial Statements" in the Company's 2015 10-K.

Individual Public Exchanges. In 2016, we are participating in individual public exchange offerings in 34 states. We have a premium deficiency reserve recorded for our estimated 2016 losses as of March 31, 2016. A portion of the premium deficiency reserve was recorded in our 2015 results for in-force contracts as of January 1, 2016. In 2017, we will participate in a substantially smaller number of individual public exchanges.

2016 RESULTS OF OPERATIONS COMPARED TO 2015 RESULTS

Our results of operations for the three months ended March 31, 2016 compared to the corresponding prior period was affected by our acquisition of Catamaran Corporation (Catamaran) in the third quarter of 2015.

Consolidated Financial Results

Revenues

The increase in revenues was primarily driven by the effect of the Catamaran acquisition, organic growth in the number of individuals served across our benefits businesses and growth across all of Optum's businesses.

Medical Costs and Medical Care Ratio

Medical costs increased due to risk-based membership growth, additional exchange losses and an extra day in the quarter due to the leap year. The medical care ratio increased due to the factors that increased medical costs, partially offset by higher levels of favorable reserve development and improved core business performance.

Operating Cost Ratio

The decrease in our operating cost ratio was due to the inclusion of Catamaran.

Income Tax Rate

Our effective tax rate decreased primarily due to the adoption of ASU 2016-09, which we adopted in the first quarter of 2016. We expect our effective tax rate for full year 2016 will be approximately 41%. See Note 1 of Notes to the Condensed Consolidated Financial Statements included in Part I, Item 1 of this report for more information about the adoption of ASU 2016-09.

Supplemental Data:
Medicare Part D stand-alone	4,990	5,105	(115	)	(2	)%

Growth in services to mid-sized employers, small groups and individuals led the overall increase in people served through risk-based benefit plans in the commercial market. Medicare Advantage increased year-over-year due to growth in people served through individual and employer-sponsored group Medicare Advantage plans. Medicaid growth was driven by the combination of new state-based awards and growth in established programs. Medicare Supplement growth reflected strong customer retention and new sales. The number of people served internationally decreased year-over-year primarily due to pricing increases in response to inflationary economic conditions in Brazil.

UnitedHealthcare's revenue growth was due to growth in the number of individuals served across its businesses and price increases reflecting underlying medical cost trends.

UnitedHealthcare's operating earnings and operating margins decreased year-over-year driven by an additional day in the quarter due to the leap year and public exchange performance, partially offset by higher levels of favorable reserve development.

Optum

Total revenues and operating earnings increased as each reporting segment reported increased revenues and earnings from operations as a result of the factors discussed below. An increased mix of pharmacy care services business, due to the acquisition of Catamaran, decreased Optum's operating margin from the prior year.

The results by segment were as follows:

OptumHealth

Revenue and earnings from operations increased at OptumHealth primarily due to growth in its health delivery businesses including expansion in neighborhood care centers.

OptumInsight

Revenue and earnings from operations at OptumInsight increased primarily due to expansion and growth in technology services, care provider revenue management services and payment services.

OptumRx

Revenue and earnings from operations increased due to the acquisition of Catamaran and strong organic growth. For more information about Catamaran, see Note 3 in Notes to the Consolidated Financial Statements in Part II, Item 8, "Financial Statements" in our 2015 10-K.

2016 Cash Flows Compared to 2015 Cash Flows

Cash flows provided by operating activities in 2016 increased primarily due to higher net earnings.

Other significant changes in sources or uses of cash year-over-year included increased net purchases of investments and cash paid for acquisitions, partially offset by an increase in proceeds from debt issuances.

Financial Condition

As of March 31, 2016, our cash, cash equivalent and available-for-sale investment balances of $33.4 billion included $10.6 billion of cash and cash equivalents (of which $500 million was available for general corporate use), $21.1 billion of debt securities and $1.7 billion of investments in equity securities. Given the significant portion of our portfolio held in cash equivalents, we do not anticipate fluctuations in the aggregate fair value of our financial assets to have a material impact on our liquidity or capital position. Our available-for-sale debt portfolio had a weighted-average duration of 3.3 years and a weighted-average credit rating of "AA" as of March 31, 2016. When multiple credit ratings are available for an individual security, the average of the available ratings is used to determine the weighted-average credit rating.

Capital Resources and Uses of Liquidity

In addition to cash flows from operations and cash and cash equivalent balances available for general corporate use, our capital resources and uses of liquidity are as follows:

Commercial Paper and Bank Credit Facilities. Our revolving bank credit facilities provide liquidity support for our commercial paper borrowing program, which facilitates the private placement of unsecured debt through third-party broker-dealers, and are available for general corporate purposes. For more information on our commercial paper and bank credit facilities, see Note 7 of Notes to the Condensed Consolidated Financial Statements included in Part I, Item 1 of this report.

Our revolving bank credit facilities contain various covenants, including covenants requiring us to maintain a defined debt to debt-plus-shareholders' equity ratio of not more than 55%. As of March 31, 2016, our debt to debt-plus-shareholders' equity ratio, as defined and calculated under the credit facilities, was approximately 47%.

Table of Contents

Long-Term Debt. Periodically, we access capital markets and issue long-term debt for general corporate purposes, for example, to meet our working capital requirements, to refinance debt, to finance acquisitions or for share repurchases. In February 2016, we issued debt to repay commercial paper borrowings, which were incurred for general corporate and working capital purposes, and to repay our 5.375% notes that were due March 15, 2016. For more information, see Note 7 of Notes to the Condensed Consolidated Financial Statements included in Part I, Item 1 of this report.

Credit Ratings. Our credit ratings as of March 31, 2016 were as follows:

The availability of financing in the form of debt or equity is influenced by many factors, including our profitability, operating cash flows, debt levels, credit ratings, debt covenants and other contractual restrictions, regulatory requirements and economic and market conditions. For example, a significant downgrade in our credit ratings or adverse conditions in the capital markets may increase the cost of borrowing for us or limit our access to capital.

Share Repurchase Program. During the three months ended March 31, 2016 , we repurchased 4 million shares at an average price of $119.49 per share. As of March 31, 2016 , we had Board authorization to purchase up to an additional 57 million shares of our common stock.

Dividends. Our quarterly cash dividend to shareholders reflects an annual dividend rate of $2.00 per share. Declaration and payment of future quarterly dividends is at the discretion of the Board and may be adjusted as business needs or market conditions change.

For additional liquidity discussion, see Note 11 of Notes to the Consolidated Financial Statements in Part II, Item 8, "Financial Statements" and "Management's Discussion and Analysis of Financial Condition and Results of Operations" in Part II, Item 7 in our 2015 10-K.

CONTRACTUAL OBLIGATIONS AND COMMITMENTS

A summary of future obligations under our various contractual obligations and commitments as of December 31, 2015 was disclosed in our 2015 10-K. During the three months ended March 31, 2016 , there were no material changes to this previously disclosed information outside the ordinary course of business. However, we continually evaluate opportunities to expand our operations, including through internal development of new products, programs and technology applications and acquisitions.

RECENTLY ISSUED ACCOUNTING STANDARDS

See Note 1 of Notes to the Condensed Consolidated Financial Statements in Part I, Item 1 of this report for a discussion of new accounting pronouncements that affect us.

CRITICAL ACCOUNTING ESTIMATES

In preparing our Condensed Consolidated Financial Statements, we are required to make judgments, assumptions and estimates, which we believe are reasonable and prudent based on the available facts and circumstances. These judgments, assumptions and estimates affect certain of our revenues and expenses and their related balance sheet accounts and disclosure of our contingent liabilities. We base our assumptions and estimates primarily on historical experience and consider known and projected trends. On an ongoing basis, we re-evaluate our selection of assumptions and the method of calculating our estimates. Actual results, however, may materially differ from our calculated estimates and this difference would be reported in our current operations.

Our critical accounting estimates include medical costs payable, revenues, goodwill and intangible assets and investments. For a detailed description of our critical accounting estimates, see "Management's Discussion and Analysis of Financial Condition and Results of Operations" in Part II, Item 7 of our 2015 10-K. For a detailed discussion of our significant accounting policies, see Note 2 of Notes to the Consolidated Financial Statements in Part II, Item 8, "Financial Statements" in our 2015 10-K.

FORWARD-LOOKING STATEMENTS

The statements, estimates, projections, guidance or outlook contained in this document include "forward-looking" statements within the meaning of the PSLRA. These statements are intended to take advantage of the "safe harbor" provisions of the

Table of Contents

PSLRA. Generally the words "believe," "expect," "intend," "estimate," "anticipate," "forecast," "plan," "project," "should" and similar expressions identify forward-looking statements, which generally are not historical in nature. These statements may contain information about financial prospects, economic conditions and trends and involve risks and uncertainties. We caution that actual results could differ materially from those that management expects, depending on the outcome of certain factors.

Some factors that could cause actual results to differ materially from results discussed or implied in the forward-looking statements include: our ability to effectively estimate, price for and manage our medical costs, including the impact of any new coverage requirements; new laws or regulations, or changes in existing laws or regulations, or their enforcement or application, including increases in medical, administrative, technology or other costs or decreases in enrollment resulting from U.S., Brazilian and other jurisdictions' regulations affecting the health care industry; assessments for insolvent payers under state guaranty fund laws; our ability to achieve improvement in CMS Star ratings and other quality scores that impact revenue; reductions in revenue or delays to cash flows received under Medicare, Medicaid and TRICARE programs, including sequestration and the effects of a prolonged U.S. government shutdown or debt ceiling constraints; changes in Medicare, including changes in payment methodology, the CMS Star ratings program or the application of risk adjustment data validation audits; our participation in federal and state health insurance exchanges which entail uncertainties associated with mix and volume of business; cyber-attacks or other privacy or data security incidents; failure to comply with privacy and data security regulations; regulatory and other risks and uncertainties of the pharmacy benefits management industry; competitive pressures, which could affect our ability to maintain or increase our market share; challenges to our public sector contract awards; our ability to execute contracts on competitive terms with physicians, hospitals and other service providers; failure to achieve targeted operating cost productivity improvements, including savings resulting from technology enhancement and administrative modernization; increases in costs and other liabilities associated with increased litigation, government investigations, audits or reviews; failure to manage successfully our strategic alliances or complete or receive anticipated benefits of acquisitions and other strategic transactions, including our acquisition of Catamaran; fluctuations in foreign currency exchange rates on our reported shareholders' equity and results of operations; downgrades in our credit ratings; adverse economic conditions, including decreases in enrollment resulting from increases in the unemployment rate and commercial attrition; the performance of our investment portfolio; impairment of the value of our goodwill and intangible assets in connection with dispositions or if estimated future results do not adequately support goodwill and intangible assets recorded for our existing businesses or the businesses that we acquire; increases in health care costs resulting from large-scale medical emergencies; failure to maintain effective and efficient information systems or if our technology products do not operate as intended; and our ability to obtain sufficient funds from our regulated subsidiaries or the debt or capital markets to fund our obligations, to maintain our debt to total capital ratio at targeted levels, to maintain our quarterly dividend payment cycle or to continue repurchasing shares of our common stock.

This list of important factors is not intended to be exhaustive. We discuss certain of these matters more fully, as well as certain risk factors that may affect our business operations, financial condition and results of operations, in our other periodic and current filings with the SEC, including our annual reports on Form 10-K, quarterly reports on Form 10-Q and current reports on Form 8-K. Any or all forward-looking statements we make may turn out to be wrong, and can be affected by inaccurate assumptions we might make or by known or unknown risks and uncertainties. By their nature, forward-looking statements are not guarantees of future performance or results and are subject to risks, uncertainties and assumptions that are difficult to predict or quantify. Actual future results may vary materially from expectations expressed or implied in this document or any of our prior communications. You should not place undue reliance on forward-looking statements, which speak only as of the date they are made. We do not undertake to update or revise any forward-looking statements, except as required by applicable securities laws.

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Our primary market risks are exposures to changes in interest rates that impact our investment income and interest expense and the fair value of certain of our fixed-rate investments and debt, as well as foreign currency exchange rate risk of the U.S. dollar, primarily to the Brazilian real.

We manage exposure to market interest rates by diversifying investments across different fixed income market sectors and debt across maturities, as well as by endeavoring to match our floating-rate assets and liabilities over time, either directly or through the use of interest rate swap contracts. Unrealized gains and losses on investments in available-for-sale securities are reported in comprehensive income.

Table of Contents

The following table summarizes the impact of hypothetical changes in market interest rates across the entire yield curve by 1% point or 2% points as of March 31, 2016 on our investment income and interest expense per annum, and the fair value of our investments and debt (in millions, except percentages):

nm = not meaningful


(a)	Given the low absolute level of short-term market rates on our floating-rate assets and liabilities as of March 31, 2016 , the assumed hypothetical change in interest rates does not reflect the full 100 basis point reduction in interest income or interest expense as the rate cannot fall below zero and thus the 200 basis point reduction is not meaningful.


(b)	As of March 31, 2016 , some of our investments had interest rates below 2% so the assumed hypothetical change in the fair value of investments does not reflect the full 200 basis point reduction.

We have an exposure to changes in the value of the Brazilian real to the U.S. dollar in translation of Amil's operating results at the average exchange rate over the accounting period, and Amil's assets and liabilities at the spot rate at the end of the accounting period. The gains or losses resulting from translating foreign assets and liabilities into U.S. dollars are included in equity and comprehensive income in our Condensed Consolidated Financial Statements.

An appreciation of the U.S. dollar against the Brazilian real reduces the carrying value of the net assets denominated in the Brazilian real. For example, as of March 31, 2016 , a hypothetical 10% and 25% increase in the value of the U.S. dollar against the Brazilian real would have caused a reduction in net assets of approximately $330 million and $730 million, respectively. We manage exposure to foreign currency risk by conducting our international business operations primarily in their functional currencies.


ITEM 4.	CONTROLS AND PROCEDURES

EVALUATION OF DISCLOSURE CONTROLS AND PROCEDURES

We maintain disclosure controls and procedures as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934 (Exchange Act) that are designed to provide reasonable assurance that information required to be disclosed by us in reports that we file or submit under the Exchange Act is (i) recorded, processed, summarized and reported within the time periods specified in SEC rules and forms; and (ii) accumulated and communicated to our management, including our principal executive officer and principal financial officer, as appropriate to allow timely decisions regarding required disclosure.

In connection with the filing of this quarterly report on Form 10-Q, management evaluated, under the supervision and with the participation of our Chief Executive Officer and Chief Financial Officer, the effectiveness of the design and operation of our disclosure controls and procedures as of March 31, 2016 . Based upon that evaluation, our Chief Executive Officer and Chief Financial Officer concluded that our disclosure controls and procedures were effective at the reasonable assurance level as of March 31, 2016 .

CHANGES IN INTERNAL CONTROL OVER FINANCIAL REPORTING
