Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	Basis of Presentation Basis of Historical Presentation The unaudited interim condensed consolidated financial statements of AbbVie Inc. (AbbVie or the company) have been prepared pursuant to the rules and regulations of the U.S. Securities and Exchange Commission. Accordingly, certain information and footnote disclosures normally included in annual financial statements prepared in accordance with generally accepted accounting principles in the United States (U.S. GAAP) have been omitted. These unaudited interim condensed consolidated financial statements should be read in conjunction with the company’s audited consolidated financial statements and notes included in the company’s Annual Report on Form 10-K for the year ended December 31, 2019 . It is management’s opinion that these financial statements include all normal and recurring adjustments necessary for a fair presentation of the company’s financial position and operating results. Net revenues and net earnings for any interim period are not necessarily indicative of future or annual results. Certain reclassifications were made to conform the prior period interim condensed consolidated financial statements to the current period presentation. On May 8, 2020, AbbVie completed its previously announced acquisition of Allergan plc (Allergan). Refer to Note 4 for additional information regarding this acquisition. Recent Accounting Pronouncements Recently Adopted Accounting Pronouncements ASU No. 2016-13 In June 2016, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) No. 2016-13, Financial Instruments - Credit Losses (Topic 326) . The standard changes how credit losses are measured for most financial assets and certain other instruments. For trade and other receivables, held-to-maturity debt securities, loans and other financial instruments, the standard requires the use of a new forward-looking "expected credit loss" model that generally will result in the earlier recognition of allowances for losses. For available-for-sale debt securities with unrealized losses, the standard now requires allowances to be recorded instead of reducing the amortized cost of the investment. AbbVie adopted the standard in the first quarter of 2020. The adoption did not have a material impact on the company's consolidated financial statements. Upon adoption of the standard, accounts receivable are stated at amortized cost less allowance for credit losses. The allowance for credit losses reflects the best estimate of future losses over the contractual life of outstanding accounts receivable and is determined on the basis of historical experience, specific allowances for known troubled accounts, other currently available information including customer financial condition, and both current and forecasted economic conditions. There were no significant changes in credit loss risk factors that impacted the company's recorded allowance during the six months ended June 30, 2020 . Recent Accounting Pronouncements Not Yet Adopted ASU No. 2019-12 In December 2019, the FASB issued ASU No. 2019-12, Income Taxes (Topic 740) . The standard includes simplifications related to accounting for income taxes including removing certain exceptions related to the approach for intraperiod tax allocation and the recognition of deferred tax liabilities for outside basis differences. The standard also clarifies the accounting for transactions that result in a step-up in the tax basis of goodwill. The standard will be effective for AbbVie starting with the first quarter of 2021. AbbVie is currently assessing the impact of this guidance on its consolidated financial statements.

Earnings Per Share [Abstract]
Earnings Per Share	Earnings Per Share AbbVie grants certain restricted stock units (RSUs) that are considered to be participating securities. Due to the presence of participating securities, AbbVie calculates earnings per share (EPS) using the more dilutive of the treasury stock or the two-class method. For all periods presented, the two-class method was more dilutive. The following table summarizes the impact of the two-class method: Three months ended Six months ended (in millions, except per share data) 2020 2019 2020 2019 Basic EPS Net earnings (loss) attributable to AbbVie Inc. $ (738 ) $ 741 $ 2,272 $ 3,197 Earnings allocated to participating securities 18 8 28 17 Earnings available to common shareholders $ (756 ) $ 733 $ 2,244 $ 3,180 Weighted-average basic shares outstanding 1,647 1,480 1,564 1,480 Basic earnings (loss) per share attributable to AbbVie Inc. $ (0.46 ) $ 0.49 $ 1.44 $ 2.15 Diluted EPS Net earnings (loss) attributable to AbbVie Inc. $ (738 ) $ 741 $ 2,272 $ 3,197 Earnings allocated to participating securities 18 8 28 17 Earnings available to common shareholders $ (756 ) $ 733 $ 2,244 $ 3,180 Weighted-average shares of common stock outstanding 1,647 1,480 1,564 1,480 Effect of dilutive securities — 4 4 3 Weighted-average diluted shares outstanding 1,647 1,484 1,568 1,483 Diluted earnings (loss) per share attributable to AbbVie Inc. $ (0.46 ) $ 0.49 $ 1.43 $ 2.14 Certain shares issuable under stock-based compensation plans were excluded from the computation of EPS because the effect would have been antidilutive. The number of common shares excluded was insignificant for all periods presented.

Licensing, Acquisitions, and Other Arrangements
Licensing, Acquisitions, and Other Arrangements	Licensing, Acquisitions and Other Arrangements Acquisition of Allergan On May 8, 2020, AbbVie completed its previously announced acquisition of all outstanding equity interests in Allergan in a cash and stock transaction. Allergan is a global pharmaceutical leader focused on developing, manufacturing and commercializing branded pharmaceutical, device, biologic, surgical and regenerative medicine products for patients around the world. The combination creates a diverse entity with leadership positions across immunology, hematologic oncology, aesthetics, neuroscience, eye care and women's health . AbbVie's existing product portfolio and pipeline is enhanced with numerous Allergan assets and Allergan's product portfolio benefits from AbbVie's commercial strength, expertise and international infrastructure. Under the terms of the acquisition, each ordinary share of Allergan common stock was converted into the right to receive (i) $120.30 in cash and (ii) 0.8660 of a share of AbbVie common stock. Total consideration for the acquisition of Allergan is summarized as follows: (in millions) Cash consideration paid to Allergan shareholders (a) $ 39,675 Fair value of AbbVie common stock issued to Allergan shareholders (b) 23,979 Fair value of AbbVie equity awards issued to Allergan equity award holders (c) 430 Total consideration $ 64,084 (a) Represents cash consideration transferred of $120.30 per outstanding Allergan ordinary share based on 330 million Allergan ordinary shares outstanding at closing. (b) Represents the acquisition date fair value of 286 million shares of AbbVie common stock issued to Allergan shareholders based on the exchange ratio of 0.8660 AbbVie shares for each outstanding Allergan ordinary share at the May 8, 2020 closing price of $83.96 per share. (c) Represents the pre-acquisition service portion of the fair value of 11 million AbbVie stock options and 8 million RSUs issued to Allergan equity award holders. The acquisition of Allergan has been accounted for as a business combination using the acquisition method of accounting. The acquisition method requires, among other things, that assets acquired and liabilities assumed in a business combination be recognized at their fair values as of the acquisition date. The valuation of assets acquired and liabilities assumed has not yet been finalized as of June 30, 2020 . As a result, AbbVie recorded preliminary estimates for the fair value of assets acquired and liabilities assumed as of the acquisition date. Finalization of the valuation during the measurement period could result in a change in the amounts recorded for the acquisition date fair value of intangible assets, goodwill, property and equipment, inventories and income taxes among other items. The completion of the valuation will occur no later than one year from the acquisition date. The following table summarizes the preliminary fair value of assets acquired and liabilities assumed as of the acquisition date: (in millions) Assets acquired and liabilities assumed Cash and equivalents $ 1,537 Short-term investments 1,421 Accounts receivable 2,423 Inventories 2,370 Prepaid expenses and other current assets 1,984 Investments 137 Property and equipment 1,912 Intangible assets Developed product rights 58,280 In-process research and development 1,040 Other noncurrent assets 1,532 Short-term borrowings (60 ) Current portion of long-term debt and finance lease obligations (1,899 ) Accounts payable and accrued liabilities (5,850 ) Long-term debt and finance lease obligations (18,937 ) Deferred income taxes (4,078 ) Other long-term liabilities (4,772 ) Total identifiable net assets 37,040 Goodwill 27,044 Total assets acquired and liabilities assumed $ 64,084 The fair value step-up adjustment to inventories of $1.2 billion is being amortized to cost of products sold when the inventory is sold to customers, which is expected to be within approximately one year from the acquisition date. Intangible assets relate to $58.3 billion of developed product rights and $1.0 billion of in-process research and development (IPR&D). The acquired definite-lived intangible assets are being amortized over a weighted-average estimated useful life of approximately 9 years using the estimated pattern of economic benefit. The estimated fair values of identifiable intangible assets were determined using the "income approach" which is a valuation technique that provides an estimate of the fair value of an asset based on market participant expectations of the cash flows an asset would generate over its remaining useful life. Some of the more significant assumptions inherent in the development of these asset valuations include the estimated net cash flows for each year for each asset or product (including net revenues, cost of products sold, research and development (R&D) costs, selling and marketing costs and contributory asset charges), the appropriate discount rate necessary to measure the risk inherent in each future cash flow stream, the life cycle of each asset, the potential regulatory and commercial success risk, competitive trends impacting the asset and each cash flow stream, as well as other factors. The fair value of long-term debt was determined by quoted market prices as of the acquisition date and the total purchase price adjustment of $1.3 billion is being amortized as a reduction to interest expense, net over the lives of the related debt. Goodwill was calculated as the excess of the consideration transferred over the net assets recognized and represents the future economic benefits arising from the other assets acquired that could not be individually identified and separately recognized. Specifically, the goodwill recognized from the acquisition of Allergan represents the value of additional growth platforms and an expanded revenue base as well as anticipated operational synergies and cost savings from the creation of a single combined global organization. The goodwill is not deductible for tax purposes. Following the acquisition date, the operating results of Allergan have been included in the condensed consolidated financial statements. For the period from the acquisition date through June 30, 2020 , net revenues attributable to Allergan were $2.0 billion and operating losses attributable to Allergan were $909 million , inclusive of $961 million of intangible asset amortization and $431 million of inventory fair value step-up amortization. Acquisition-related expenses, which were comprised primarily of regulatory, financial advisory and legal fees, totaled $777 million for the three months and $781 million for the six months ended June 30, 2020 and $24 million for the three and six months ended June 30, 2019 and were included in selling, general and administrative (SG&A) expenses in the condensed consolidated statements of earnings . Pro Forma Financial Information The following table presents the unaudited pro forma combined results of AbbVie and Allergan for the three and six months ended June 30, 2020 and 2019 as if the acquisition of Allergan had occurred on January 1, 2019: Three months ended Six months ended (in millions) 2020 2019 2020 2019 Net revenues $ 11,542 $ 12,267 $ 23,761 $ 23,657 Net earnings (loss) 53 (1,735 ) 3,312 (3,726 ) The unaudited pro forma condensed combined financial information was prepared using the acquisition method of accounting and was based on the historical financial information of AbbVie and Allergan. In order to reflect the occurrence of the acquisition on January 1, 2019 as required, the unaudited pro forma financial information includes adjustments to reflect incremental amortization expense to be incurred based on the current preliminary fair values of the identifiable intangible assets acquired; the incremental cost of products sold related to the fair value adjustments associated with acquisition date inventory; the additional interest expense associated with the issuance of debt to finance the acquisition; and the reclassification of acquisition-related costs incurred during the three and six months ended June 30, 2020 to the six months ended June 30, 2019 . The unaudited pro forma financial information is not necessarily indicative of what the consolidated results of operations would have been had the acquisition been completed on January 1, 2019. In addition, the unaudited pro forma financial information is not a projection of future results of operations of the combined company nor does it reflect the expected realization of any synergies or cost savings associated with the acquisition. Other Licensing & Acquisitions Activity Cash outflows related to other acquisitions and investments totaled $192 million for the six months ended June 30, 2020 and $440 million for the six months ended June 30, 2019 . AbbVie recorded acquired IPR&D charges of $853 million for the three months and six months ended June 30, 2020 and recorded acquired IPR&D charges of $91 million for the three months and $246 million for the six months ended June 30, 2019 . Genmab A/S In June 2020, AbbVie and Genmab A/S (Genmab) entered into a collaboration agreement to jointly develop and commercialize three of Genmab's early-stage investigational bispecific antibody therapeutics and entered into a discovery research collaboration for future differentiated antibody therapeutics for the treatment of cancer. Under the terms of the agreement, Genmab granted to AbbVie an exclusive license to its epcoritamab (DuoBody-CD3xCD20), DuoHexaBody-CD37 and DuoBody-CD3x5T4 programs. For epcoritamab, the companies will share commercial responsibilities in the U.S. and Japan, with AbbVie responsible for further global commercialization. Genmab will record net revenues in the U.S. and Japan, and the parties will share equally in pre-tax profits from these sales. Genmab will receive tiered royalties on remaining global sales. For the discovery research partnership, Genmab will conduct Phase 1 studies for these programs and AbbVie retains the right to opt-in to program development. AbbVie made an upfront payment of $750 million , which was recorded to IPR&D in the three months ended June 30, 2020 . AbbVie could make additional payments of up to $3.2 billion upon the achievement of certain development, regulatory and commercial milestones for all programs.

Fair Value Disclosures [Abstract]
Financial Instruments and Fair Value Measures	Financial Instruments and Fair Value Measures Risk Management Policy See Note 11 to the company's Annual Report on Form 10-K for the year ended December 31, 2019 for a summary of AbbVie's risk management policy and use of derivative instruments. Financial Instruments Various AbbVie foreign subsidiaries enter into foreign currency forward exchange contracts to manage exposures to changes in foreign exchange rates for anticipated intercompany transactions denominated in a currency other than the functional currency of the local entity. These contracts, with notional amounts totaling $1.5 billion at June 30, 2020 and $957 million at December 31, 2019 , are designated as cash flow hedges and are recorded at fair value. The durations of these forward exchange contracts were generally less than 18 months . Accumulated gains and losses as of June 30, 2020 are reclassified from accumulated other comprehensive income (AOCI) and included in cost of products sold at the time the products are sold, generally not exceeding six months from the date of settlement. In the third quarter of 2019, the company entered into treasury rate lock agreements with notional amounts totaling $10.0 billion to hedge exposure to variability in future cash flows resulting from changes in interest rates related to the issuance of long-term debt in connection with the acquisition of Allergan. The treasury rate lock agreements were designated as cash flow hedges and recorded at fair value. The agreements were net settled upon issuance of the senior notes in November 2019 and the resulting net gain was recognized in other comprehensive income (loss). This gain is reclassified to interest expense, net over the term of the related debt. In the fourth quarter of 2019, the company entered into interest rate swap contracts with notional amounts totaling $2.3 billion at June 30, 2020 and December 31, 2019 . The effect of the hedge contracts is to change a floating-rate interest obligation to a fixed rate for that portion of the floating-rate debt. The contracts were designated as cash flow hedges and are recorded at fair value. Realized and unrealized gains or losses are included in AOCI and are reclassified to interest expense, net over the lives of the floating-rate debt. The company also enters into foreign currency forward exchange contracts to manage its exposure to foreign currency denominated trade payables and receivables and intercompany loans. These contracts are not designated as hedges and are recorded at fair value. Resulting gains or losses are reflected in net foreign exchange gain or loss in the condensed consolidated statements of earnings and are generally offset by losses or gains on the foreign currency exposure being managed. These contracts had notional amounts totaling $7.0 billion at June 30, 2020 and $7.1 billion at December 31, 2019 . The company also uses foreign currency forward exchange contracts or foreign currency denominated debt to hedge its net investments in certain foreign subsidiaries and affiliates. The company had foreign currency forward exchange contracts with notional amounts totaling €971 million , £204 million and CHF62 million at June 30, 2020 and December 31, 2019 . The company also had an aggregate principal amount of senior Euro notes designated as net investment hedges of €7.3 billion at June 30, 2020 and €3.6 billion at December 31, 2019 . The company uses the spot method of assessing hedge effectiveness for derivative instruments designated as net investment hedges. Realized and unrealized gains and losses from these hedges are included in AOCI and the initial fair value of hedge components excluded from the assessment of effectiveness is recognized in interest expense, net over the life of the hedging instrument. AbbVie is a party to interest rate swap contracts designated as fair value hedges with notional amounts totaling $4.8 billion at June 30, 2020 and $10.8 billion at December 31, 2019 . The effect of the hedge contracts is to change a fixed-rate interest obligation to a floating rate for that portion of the debt. AbbVie records the contracts at fair value and adjusts the carrying amount of the fixed-rate debt by an offsetting amount. No amounts are excluded from the assessment of effectiveness for cash flow hedges or fair value hedges.

The following table summarizes the bases used to measure certain assets and liabilities carried at fair value on a recurring basis on the condensed consolidated balance sheet as of June 30, 2020 : Basis of fair value measurement (in millions) Total Quoted prices in active markets for identical assets Significant other observable Significant Assets Cash and equivalents $ 6,017 $ 1,432 $ 4,585 $ — Money market funds and time deposits 12 — 12 — Debt securities 50 — 50 — Equity securities 95 95 — — Interest rate swap contracts 170 — 170 — Foreign currency contracts 53 — 53 — Total assets $ 6,397 $ 1,527 $ 4,870 $ — Liabilities Interest rate swap contracts $ 47 $ — $ 47 $ — Foreign currency contracts 30 — 30 — Contingent consideration 8,213 — — 8,213 Total liabilities $ 8,290 $ — $ 77 $ 8,213 The following table summarizes the bases used to measure certain assets and liabilities carried at fair value on a recurring basis on the condensed consolidated balance sheet as of December 31, 2019 : Basis of fair value measurement (in millions) Total Quoted prices in active markets for identical assets Significant other observable Significant Assets Cash and equivalents $ 39,924 $ 1,542 $ 38,382 $ — Debt securities 3 — 3 — Equity securities 24 24 — — Interest rate swap contracts 31 — 31 — Foreign currency contracts 22 — 22 — Total assets $ 40,004 $ 1,566 $ 38,438 $ — Liabilities Interest rate swap contracts $ 76 $ — $ 76 $ — Foreign currency contracts 56 — 56 — Contingent consideration 7,340 — — 7,340 Total liabilities $ 7,472 $ — $ 132 $ 7,340 Equity securities consist of investments for which the fair values were determined by using the published market price per unit multiplied by the number of units held, without consideration of transaction costs. The derivatives entered into by the company were valued using observable market inputs including published interest rate curves and both forward and spot prices for foreign currencies. The fair value measurements of the contingent consideration liabilities were determined based on significant unobservable inputs, including the discount rate, estimated probabilities and timing of achieving specified development, regulatory and commercial milestones and the estimated amount of future sales of the acquired products. The potential contingent consideration payments are estimated by applying a probability-weighted expected payment model for contingent milestone payments and a Monte Carlo simulation model for contingent royalty payments, which are then discounted to present value. Changes to the fair value of the contingent consideration liabilities can result from changes to one or a number of inputs, including discount rates, the probabilities of achieving the milestones, the time required to achieve the milestones and estimated future sales. Significant judgment is employed in determining the appropriateness of certain of these inputs. Changes to the inputs described above could have a material impact on the company's financial position and results of operations in any given period. The fair value of the company's contingent consideration liabilities as of June 30, 2020 was calculated using the following significant unobservable inputs: Range Weighted average (a) Discount rate 0.5% - 2.6% 1.6 % Probability of payment for unachieved milestones 16% - 57% 54 % Probability of payment for royalties by indication (b) 16% - 100% 89 % Projected year of payments 2020 - 2034 2027 (a) Unobservable inputs were weighted by the relative fair value of the contingent consideration liabilities. (b) Excludes early stage indications with 0% estimated probability of payment and includes approved indications with 100% probability of payment. Excluding approved indications, the estimated probability of payment ranged from 16% to 56% at June 30, 2020 . There have been no transfers of assets or liabilities into or out of Level 3 of the fair value hierarchy. The following table presents the changes in fair value of total contingent consideration liabilities which are measured using Level 3 inputs: Six months ended (in millions) 2020 2019 Beginning balance $ 7,340 $ 4,483 Additions (a) 121 — Change in fair value recognized in net earnings 881 2,473 Payments (129 ) (167 ) Ending balance $ 8,213 $ 6,789 (a) Represents contingent consideration liabilities assumed in the Allergan acquisition. The change in fair value recognized in net earnings is recorded in other expense, net in the condensed consolidated statements of earnings . Certain financial instruments are carried at historical cost or some basis other than fair value.

The company records these investments at cost and remeasures them to fair value based on certain observable price changes or impairment events as they occur. The carrying amount of these investments was $91 million as of June 30, 2020 and $66 million as of December 31, 2019 . No significant cumulative upward or downward adjustments have been recorded for these investments as of June 30, 2020 . Concentrations of Risk Of total net accounts receivable, three U.S. wholesalers accounted for 73% as of June 30, 2020 and 68% as of December 31, 2019 , and substantially all of AbbVie’s net revenues in the United States were to these three wholesalers. Humira (adalimumab) is AbbVie’s single largest product and accounted for approximately 50% of AbbVie’s total net revenues for the six months ended June 30, 2020 and 58% for the six months ended June 30, 2019 . Debt and Credit Facilities Allergan-Related Financing In connection with the acquisition of Allergan, in May 2020, the company borrowed $3.0 billion under a $6.0 billion term loan credit agreement, of which $1.0 billion was outstanding under a floating rate three-year term loan tranche and $2.0 billion outstanding under a floating rate five-year term loan tranche as of June 30, 2020 . Subsequent to these borrowings, AbbVie terminated the unused commitments of the lenders under the term loan. In May 2020, AbbVie completed its previously announced offers to exchange any and all outstanding notes of certain series issued by Allergan for new notes to be issued by AbbVie and cash. Following the settlement of the exchange offers, AbbVie issued $14.0 billion and €3.1 billion of new notes in exchange for the Allergan notes tendered in the exchange offers. The aggregate principal amount of Allergan notes that remained outstanding following the settlement of the exchange offers was approximately $1.5 billion and €635 million . The exchange transaction was accounted for as a modification of the assumed debt instruments. The following table summarizes acquired debt outstanding as of June 30, 2020 : (dollars in millions) June 30, 2020 Senior USD notes 3.375% Senior Notes due 2020 $ 650 4.875% Senior Notes due 2021 450 5.000% Senior Notes due 2021 1,200 3.450% Senior Notes due 2022 2,878 3.250% Senior Notes due 2022 1,700 2.800% Senior Notes due 2023 350 3.850% Senior Notes due 2024 1,032 3.800% Senior Notes due 2025 3,021 4.550% Senior Notes due 2035 1,789 4.625% Senior Notes due 2042 457 4.850% Senior Notes due 2044 1,074 4.750% Senior Notes due 2045 881 Senior Euro notes Floating Rate Notes due 2020 (€700 principal) 788 0.500% Senior Notes due 2021 (€750 principal) 845 1.500% Senior Notes due 2023 (€500 principal) 563 1.250% Senior Notes due 2024 (€700 principal) 788 2.625% Senior Notes due 2028 (€500 principal) 563 2.125% Senior Notes due 2029 (€550 principal) 619 Unamortized purchase price adjustments of Allergan debt 1,312 Total acquired debt outstanding $ 20,960 Other Long-Term Debt In May 2020, the company repaid $3.8 billion aggregate principal amount of 2.5% senior notes at maturity.

Income Taxes

Income Taxes	6 Months Ended
	Jun. 30, 2020
Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes The effective tax rate was 7% income tax expense on pre-tax loss for the three months ended June 30, 2020 and 6% income tax expense on pre-tax income for the six months ended June 30, 2020 . The effective tax rate was 8% and 5% for the three months and six months ended June 30, 2019 , respectively. The effective tax rate in each period differed from the U.S. statutory tax rate of 21% principally due to the benefit from foreign operations which reflects the impact of lower income tax rates in locations outside the United States, tax incentives in Puerto Rico and other foreign tax jurisdictions and business development activities . The change in the effective tax rate for the three months ended June 30, 2020 over prior year was principally due to the unfavorable impact of non-deductible Allergan acquisition related costs, the impact of changes in contingent consideration liabilities and collaboration related costs. These contributed to net income tax expense on a pre-tax loss for the three months ended June 30, 2020. Due to the potential for resolution of federal, state and foreign examinations and the expiration of various statutes of limitations, it is reasonably possible that the company’s gross unrecognized tax benefits balance may change within the next 12 months by up to $156 million .

Legal Proceedings and Contingen

Legal Proceedings and Contingencies	6 Months Ended
	Jun. 30, 2020
Commitments and Contingencies Disclosure [Abstract]
Legal Proceedings and Contingencies	Legal Proceedings and Contingencies AbbVie is subject to contingencies, such as various claims, legal proceedings and investigations regarding product liability, intellectual property, commercial, securities and other matters that arise in the normal course of business. Loss contingency provisions are recorded for probable losses at management’s best estimate of a loss, or when a best estimate cannot be made, a minimum loss contingency amount within a probable range is recorded. The recorded accrual balance for litigation was approximately $330 million as of June 30, 2020 and $290 million as of December 31, 2019 . Initiation of new legal proceedings or a change in the status of existing proceedings may result in a change in the estimated loss accrued by AbbVie. While it is not feasible to predict the outcome of all proceedings and exposures with certainty, management believes that their ultimate disposition should not have a material adverse effect on AbbVie’s consolidated financial position, results of operations or cash flows. Subject to certain exceptions specified in the separation agreement by and between Abbott Laboratories (Abbott) and AbbVie, AbbVie assumed the liability for, and control of, all pending and threatened legal matters related to its business, including liabilities for any claims or legal proceedings related to products that had been part of its business, but were discontinued prior to the distribution, as well as assumed or retained liabilities, and will indemnify Abbott for any liability arising out of or resulting from such assumed legal matters. A lawsuit against Unimed Pharmaceuticals, LLC, Solvay Pharmaceuticals, Inc. (a company Abbott acquired in February 2010 and now known as AbbVie Products LLC) and others remains pending in the United States District Court for the Northern District of Georgia for pre-trial purposes under the Multi-District Litigation (MDL) Rules as In re: AndroGel Antitrust Litigation , MDL No. 2084. This case, brought by a direct AndroGel purchaser, generally alleges Solvay's 2006 patent litigation settlement agreements and related agreements with three generic companies violate federal antitrust laws. The plaintiff seeks monetary damages and attorneys' fees. This lawsuit is no longer material to AbbVie and AbbVie will no longer report on this case. In September 2014, the FTC filed a lawsuit, FTC v. AbbVie Inc., et al. , against AbbVie and others in the United States District Court for the Eastern District of Pennsylvania, alleging that the 2011 patent litigation with two generic companies regarding AndroGel was sham litigation and the settlements of that litigation violated federal antitrust law. In May 2015, the court dismissed the FTC’s settlement-related claim. In June 2018, following a bench trial, the court found for the FTC on its sham litigation claim and ordered a disgorgement remedy of $448 million , plus prejudgment interest. The court denied the FTC’s request for injunctive relief. AbbVie is appealing the court’s liability and disgorgement rulings and, based on an assessment of the merits of that appeal, no liability has been accrued for this matter. The FTC is also appealing aspects of the court’s trial ruling and the dismissal of its settlement-related claim. In August 2019, direct purchasers of AndroGel filed a lawsuit, King Drug Co. of Florence, Inc., et al. v. AbbVie Inc., et al. , against AbbVie and others in the United States District Court for the Eastern District of Pennsylvania, making allegations similar to those in In re: AndroGel Antitrust Litigation (No. II) , MDL No. 2084 (above) and FTC v. AbbVie Inc. (above). In May 2020, Perrigo Company and related entities filed a lawsuit against AbbVie and others in the United States District Court for the Eastern District of Pennsylvania, making sham litigation allegations similar to those in FTC v. AbbVie Inc . (above). Lawsuits are pending against AbbVie and others generally alleging that the 2005 patent litigation settlement involving Niaspan entered into between Kos Pharmaceuticals, Inc. (a company acquired by Abbott in 2006 and presently a subsidiary of AbbVie) and a generic company violates federal and state antitrust laws and state unfair and deceptive trade practices and unjust enrichment laws. Plaintiffs generally seek monetary damages and/or injunctive relief and attorneys' fees. The lawsuits consist of four individual plaintiff lawsuits and two consolidated purported class actions: one brought by Niaspan direct purchasers and one brought by Niaspan end-payers. The cases are pending in the United States District Court for the Eastern District of Pennsylvania for coordinated or consolidated pre-trial proceedings under the MDL Rules as In re: Niaspan Antitrust Litigation , MDL No. 2460. In August 2019, the court certified a class of direct purchasers of Niaspan. In June 2020, the court denied the end-payers' motion to certify a class. In October 2016, the Orange County, California District Attorney’s Office filed a lawsuit on behalf of the State of California regarding the Niaspan patent litigation settlement in Orange County Superior Court, asserting a claim under the unfair competition provision of the California Business and Professions Code seeking injunctive relief, restitution, civil penalties and attorneys’ fees. In June 2020, the California Supreme Court reversed a lower court's ruling and held that the District Attorney’s suit may proceed on a statewide basis. Between March and May 2019, 12 putative class action lawsuits were filed in the United States District Court for the Northern District of Illinois by indirect Humira purchasers, alleging that AbbVie’s settlements with biosimilar manufacturers and AbbVie’s Humira patent portfolio violate state and federal antitrust laws. The court consolidated these lawsuits as In re: Humira (Adalimumab) Antitrust Litigation . In June 2020, the court dismissed the consolidated litigation with prejudice. The plaintiffs have indicated they plan to appeal. In July 2019, the New Mexico Attorney General filed a lawsuit, State of New Mexico ex rel. Balderas v. AbbVie Inc., et al. , in New Mexico District Court for Santa Fe County against AbbVie and other companies alleging their marketing of AndroGel violated New Mexico’s Unfair Practices Act. In September 2018, the Commissioner of the California Department of Insurance intervened in a qui tam lawsuit, State of California and Lazaro Suarez v. AbbVie Inc., et al. , brought under the California Insurance Frauds Prevention Act, in California Superior Court for Alameda County. The Department of Insurance’s complaint alleged that, through patient and reimbursement support services and other services and items of value provided in connection with Humira, AbbVie caused the submission of fraudulent commercial insurance claims for Humira in violation of the California statute. The complaint sought injunctive relief, an assessment of up to three times the amount of the claims at issue, and civil penalties. AbbVie has reached a resolution of the Department of Insurance's lawsuit that allows AbbVie to continue to operate its Humira patient support program. In addition, a federal securities lawsuit ( Holwill v. AbbVie Inc., et al .) is pending in the United States District Court for the Northern District of Illinois) against AbbVie, its chief executive officer and former chief financial officer, alleging that reasons stated for Humira sales growth in financial filings between 2013 and 2017 were misleading because they omitted the conduct alleged in the Department of Insurance’s complaint. In February 2020, a shareholder derivative lawsuit that had previously been filed in the United States District Court for the Northern District of Illinois and then voluntarily dismissed was refiled in the United States District Court for the District of Delaware. The lawsuit, Elfers v. Gonzalez, et al. , alleges that certain AbbVie directors and officers breached their fiduciary duties in connection with Humira patient and reimbursement support services and other services and items of value, as alleged in the State of California case discussed above, and in connection with the announcements of results of AbbVie’s 2018 Dutch auction tender offer. In June 2016, a lawsuit, Elliott Associates, L.P., et al. v. AbbVie Inc. , was filed by five investment funds against AbbVie in the Cook County, Illinois Circuit Court alleging that AbbVie made misrepresentations and omissions in connec tion with its proposed t ransaction with Shire. Similar lawsuits were filed between July 2017 and October 2019 against AbbVie and in some instances its chief executive officer in the same court by additional investment funds. Plaintiffs seek compensatory and punitive damages. Product liability cases were filed in which plaintiffs generally allege that AbbVie and other manufacturers of TRTs did not adequately warn about risks of certain injuries, primarily heart attacks, strokes and blood clots. Approximately 3,500 claims against AbbVie are consolidated for pre-trial purposes in the United States District Court for the Northern District of Illinois under the MDL Rules as In re: Testosterone Replacement Therapy Products Liability Litigation , MDL No. 2545. Approximately 175 claims against AbbVie are pending in various state courts. Plaintiffs generally seek compensatory and punitive damages. In November 2018, AbbVie entered into a Master Settlement Agreement with the Plaintiffs’ Steering Committee in the MDL encompassing existing claims in all courts. All proceedings in pending cases are effectively stayed during the settlement administration process. Product liability cases are pending in which plaintiffs generally allege that AbbVie did not adequately warn about risk of certain injuries, primarily various birth defects, arising from use of Depakote. Approximately 95 cases are pending in the United States District Court for the Southern District of Illinois, and approximately 14 others are pending in various federal and state courts. Plaintiffs generally seek compensatory and punitive damages. Approximately ninety-five percent of these pending cases, plus other unfiled claims, are subject to confidential settlement agreements and are expected to be dismissed with prejudice. Lawsuits are pending against Forest Laboratories, LLC and others generally alleging that 2009 and 2010 patent litigation settlements involving Namenda entered into between Forest and generic companies, and other conduct by Forest involving Namenda, violated state antitrust, unfair and deceptive trade practices, and unjust enrichment laws. Plaintiffs generally seek monetary damages, injunctive relief and attorneys’ fees. The lawsuits, purported class actions filed by indirect purchasers of Namenda, are consolidated as In re: Namenda Indirect Purchaser Antitrust Litigation in the United States District Court for the Southern District of New York. Similar lawsuits brought by direct purchasers of Namenda were resolved and dismissed in May 2020. Lawsuits are pending against Allergan Inc. generally alleging that Allergan’s petitioning to the U.S. Patent Office and Food and Drug Administration, and other conduct by Allergan, involving Restasis violated federal and state antitrust laws, and state unfair and deceptive trade practices, and unjust enrichment laws. Plaintiffs generally seek monetary damages, injunctive relief and attorneys’ fees. The lawsuits, purported class actions filed by indirect purchasers of Restasis, are consolidated for pre-trial purposes in the United States District Court for the Eastern District of New York under the MDL Rules as In re: Restasis (Cyclosporine Ophthalmic Emulsion) Antitrust Litigation, MDL 2819. In June 2020, the court certified a class of indirect purchasers of Restasis. Similar lawsuits brought by direct purchasers of Restasis are subject to a settlement that was preliminarily approved by the court in May 2020 and is pending final approval, and by Restasis direct purchaser assignees were resolved and dismissed in March 2020. Lawsuits are pending against Allergan and certain of its current and former officers alleging they made misrepresentations and omissions regarding Allergan’s former Actavis generics unit and its alleged anticompetitive conduct with other generic drug companies. The lawsuits were filed by Allergan shareholders and consist of three purported class actions and one individual action that have been consolidated in the U.S. District Court for the District of New Jersey as In re: Allergan Generic Drug Pricing Securities Litigation, and one individual action that is pending in New Jersey state court. The plaintiffs seek monetary damages and attorneys’ fees. Lawsuits have been filed in which plaintiffs generally allege that Allergan and several other manufacturers improperly promoted and sold prescription opioid products. Approximately 3,050 matters are pending against Allergan. The federal court cases are consolidated for pre-trial purposes in the United States District Court for the Northern District of Ohio under the MDL rules as In re: National Prescription Opiate Litigation, MDL No. 2804. Approximately 279 of the claims are pending in various state courts. The plaintiffs in these cases, which include states, counties, cities, and Native American tribes, generally seek compensatory damages. Lawsuits are pending against Allergan and certain of its current and former officers alleging they made misrepresentations and omissions regarding Allergan's textured breast implants. The lawsuits, which were filed by Allergan shareholders, have been consolidated in the United States District Court for the Southern District of New York as In re: Allergan plc Securities Litigation. The plaintiffs generally seek compensatory damages and attorneys’ fees. In September 2019, the court partially granted Allergan's motion to dismiss. In 2018, a qui tam lawsuit, U.S. ex rel. Silbersher v. Allergan Inc., et al., was filed in the United States District Court for the Northern District of California against several Allergan entities and others, alleging that their conduct before the U.S. Patent Office resulted in false claims for payment being made to federal and state healthcare payors for Namenda XR and Namzaric. The plaintiff-relator seeks damages and attorneys' fees under the federal False Claims Act and state law analogues. The federal government and state governments declined to intervene in the lawsuit. In March 2017, AbbVie filed a lawsuit, AbbVie Inc. v. Novartis Vaccines and Diagnostics, Inc. and Grifols Worldwide Operations Ltd., in the United States District Court for the Northern District of California against Novartis Vaccines and Grifols Worldwide seeking a declaratory judgment that 11 hepatitis C virus (HCV)-related patents licensed to AbbVie in 2002 are invalid. The parties entered into a settlement agreement and the case was dismissed on March 26, 2020. Pharmacyclics LLC, a wholly owned subsidiary of AbbVie, is seeking to enforce its patent rights relating to ibrutinib capsules (a drug Pharmacyclics sells under the trademark Imbruvica). In February 2018 and March 2020, cases were filed in the United States District Court for the District of Delaware against the following defendants: Zydus Worldwide DMCC and Cadila Healthcare Limited; and Sandoz Inc., and Lek Pharmaceuticals D.D. In each case, Pharmacyclics alleges the defendants' proposed generic ibrutinib product infringes certain Pharmacyclics patents and seeks declaratory and injunctive relief.

This operating structure enables the Chief Executive Officer, as chief operating decision maker (CODM), to allocate resources and assess business performance on a global basis in order to achieve established long-term strategic goals. Consistent with this structure, a global research and development and supply chain organization is responsible for the discovery, manufacturing and supply of products. Commercial efforts that coordinate the marketing, sales and distribution of these products are organized by geographic region or therapeutic area. All of these activities are supported by a global corporate administrative staff. The determination of a single business segment is consistent with the consolidated financial information regularly reviewed by the CODM for purposes of assessing performance, allocating resources and planning and forecasting future periods.

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Recent Accounting Pronouncements	Recent Accounting Pronouncements Recently Adopted Accounting Pronouncements ASU No. 2016-13 In June 2016, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) No. 2016-13, Financial Instruments - Credit Losses (Topic 326) . The standard changes how credit losses are measured for most financial assets and certain other instruments. For trade and other receivables, held-to-maturity debt securities, loans and other financial instruments, the standard requires the use of a new forward-looking "expected credit loss" model that generally will result in the earlier recognition of allowances for losses. For available-for-sale debt securities with unrealized losses, the standard now requires allowances to be recorded instead of reducing the amortized cost of the investment. AbbVie adopted the standard in the first quarter of 2020. The adoption did not have a material impact on the company's consolidated financial statements. Upon adoption of the standard, accounts receivable are stated at amortized cost less allowance for credit losses. The allowance for credit losses reflects the best estimate of future losses over the contractual life of outstanding accounts receivable and is determined on the basis of historical experience, specific allowances for known troubled accounts, other currently available information including customer financial condition, and both current and forecasted economic conditions. There were no significant changes in credit loss risk factors that impacted the company's recorded allowance during the six months ended June 30, 2020 . Recent Accounting Pronouncements Not Yet Adopted ASU No. 2019-12 In December 2019, the FASB issued ASU No. 2019-12, Income Taxes (Topic 740) . The standard includes simplifications related to accounting for income taxes including removing certain exceptions related to the approach for intraperiod tax allocation and the recognition of deferred tax liabilities for outside basis differences. The standard also clarifies the accounting for transactions that result in a step-up in the tax basis of goodwill. The standard will be effective for AbbVie starting with the first quarter of 2021. AbbVie is currently assessing the impact of this guidance on its consolidated financial statements.
