On February 3, 2017, we completed the sale of our global infusion systems net assets, HIS, to ICU Medical. The operating results of HIS are included in our condensed consolidated statement of income and EH’s operating results through February 2, 2017 and, therefore, our financial results, and EH’s operating results, for the second quarter of 2017 do not reflect any contribution from HIS global operations, while our financial results, and EH’s operating results, for the first six months of 2017 reflect approximately one month of HIS domestic operations and approximately two months of HIS international operations. Our financial results, and EH’s operating results, for 2018 do not reflect any contribution from HIS global operations.

On December 22, 2016, which fell in the first fiscal quarter of 2017 for our international operations, we acquired the development and commercialization rights to AstraZeneca’s small molecule anti-infectives business, primarily outside the U.S. Commencing from the acquisition date, our financial statements reflect the assets, liabilities, operating results and cash flows of this business, and, in accordance with our international reporting period, our financial results, EH’s operating results, and cash flows for the second quarter and first six months of 2017 reflect approximately three months and five months, respectively, of the small molecule anti-infectives business acquired from AstraZeneca. Our financial results, EH’s operating results, and cash flows for the second quarter and first six months of 2018 reflect three months and six months, respectively, of the small molecule anti-infective business acquired from AstraZeneca.

•

Customers––Our biopharmaceutical products are sold principally to wholesalers but we also sell directly to retailers, hospitals, clinics, government agencies and pharmacies, and, in the case of our vaccine products in the U.S., we primarily sell directly to the CDC, wholesalers and individual provider offices. Our consumer healthcare customers include retailers and, to a lesser extent, wholesalers and distributors.

•	Our Sales Contracts––Sales on credit are typically under short-term contracts. Collections are based on market payment cycles common in various markets, with shorter cycles in the U.S. Sales are adjusted for sales allowances, chargebacks, rebates and sales returns and cash discounts. Sales returns occur due to loss of exclusivity, product recalls or a changing competitive environment.

•

Deductions from Revenues––Our gross product revenues are subject to a variety of deductions, which generally are estimated and recorded in the same period that the revenues are recognized. Such variable consideration represents chargebacks, rebates, sales allowances and sales returns. These deductions represent estimates of the related obligations and, as such, knowledge and judgment is required when estimating the impact of these revenue deductions on gross sales for a reporting period.

•

In the U.S., we sell our products to distributors and hospitals under our sales contracts. However, we also have contracts with managed care or pharmacy benefit managers and legislatively mandated contracts with the federal and state governments under which we provide rebates to them based on medicines utilized by the lives they cover. We record provisions for Medicare, Medicaid, and performance-based contract pharmaceutical rebates based upon our experience ratio of rebates paid and actual prescriptions written during prior quarters. We apply the experience ratio to the respective period’s sales to determine the rebate accrual and related expense. This experience ratio is evaluated regularly to ensure that the historical trends are as current as practicable. We estimate discounts on branded prescription drug sales to Medicare Part D participants in the Medicare “coverage gap,” also known as the “doughnut hole,” based on the historical experience of beneficiary prescriptions and consideration of the utilization that is expected to result from the discount in the coverage gap. We evaluate this estimate regularly to ensure that the historical trends and future expectations are as current as practicable. For performance-based contract rebates, we also consider current contract terms, such as changes in formulary status and rebate rates.

•

Outside the U.S., the majority of our pharmaceutical sales allowances are contractual or legislatively mandated and our estimates are based on actual invoiced sales within each period, which reduces the risk of variations in the estimation process. In certain European countries, rebates are calculated on the government’s total unbudgeted pharmaceutical spending or on specific product sales thresholds and we apply an estimated allocation factor against our actual invoiced sales to project the expected level of reimbursement. We obtain third-party information that helps us to monitor the adequacy of these accruals.

•	Provisions for pharmaceutical chargebacks (primarily reimbursements to U.S. wholesalers for honoring contracted prices to third parties) closely approximate actual amounts incurred, as we settle these deductions generally within two to five weeks of incurring the liability.

•

Provisions for pharmaceutical sales returns are based on a calculation for each market that incorporates the following, as appropriate: local returns policies and practices; historical returns as a percentage of sales; an understanding of the reasons for past returns; estimated shelf life by product; an estimate of the amount of time between shipment and return or lag time; and any other factors that could impact the estimate of future returns, such as loss of exclusivity, product recalls or a changing competitive environment. Generally, returned products are destroyed, and customers are refunded the sales price in the form of a credit.

•	We record sales incentives as a reduction of revenues at the time the related revenues are recorded or when the incentive is offered, whichever is later. We estimate the cost of our sales incentives based on our historical experience with similar incentives programs to predict customer behavior.

$394 million (pre-tax) for collaborative arrangements where the period over which upfront, pre-approval and regulatory approval milestone payments received from our collaboration partners are recognized in Other (income)/deductions—net over a reduced period. Under the new standard, the income from upfront and pre-approval milestone payments due to us is typically recognized over the development period for the collaboration when our performance obligation, in addition to granting a license, is to provide research and development services to our collaboration partners, and major regulatory approval milestones are typically recognized immediately when earned as the related development period has ended. The income from upfront and milestone payments is typically recognized immediately as earned if our performance obligation, in addition to granting a license, is only for commercialization activities. Under the old standard, this income was recognized

In connection with acquisition activity, we typically incur costs associated with executing the transactions, integrating the acquired operations (which may include expenditures for consulting and the integration of systems and processes), and restructuring the combined company (which may include charges related to employees, assets and activities that will not continue in the combined company); and

•	In connection with our cost-reduction/productivity initiatives, we typically incur costs and charges associated with site closings and other facility rationalization actions, workforce reductions and the expansion of shared services, including the development of global systems.

•	Optimization of our manufacturing plant network to support IH and EH products and pipelines. During 2017-2019, we expect to incur costs of approximately $800 million related to this initiative. Through July 1, 2018, we incurred approximately $283 million associated with this initiative.

•	Activities in non-manufacturing related areas, which include further centralization of our corporate and platform functions, as well as other activities where opportunities are identified. During 2017-2019, we expect to incur costs of approximately $400 million related to this initiative. Through July 1, 2018, we incurred approximately $217 million associated with this initiative.

(a)

In the three and six months ended July 1, 2018, restructuring credits are associated with cost-reduction and productivity initiatives not associated with acquisitions, as well as acquisition-related costs, primarily associated with Hospira. In the three and six months ended July 2, 2017, restructuring credits are largely associated with cost-reduction and productivity initiatives not associated with acquisitions, partially offset by charges related to our acquisition of mainly Anacor in the second quarter of 2017, and mainly Anacor and Medivation in the first six months of 2017. In the three and six months ended July 1, 2018, Employee terminations primarily include revisions of our estimates of severance benefits. Employee termination costs are generally recorded when the actions are probable and estimable and include accrued severance benefits, many of which may be paid out during periods after termination.

•	For the second quarter of 2018, IH ($12 million income); EH ($2 million); manufacturing operations ($13 million); and Corporate ($26 million income).

•	For the first six months of 2018, IH ($12 million income); EH ($12 million income); WRD/GPD ($2 million income); manufacturing operations ($15 million); and Corporate ($22 million income).

•	For the second quarter of 2017, IH ($8 million income); EH ($7 million); WRD/GPD ($14 million income); manufacturing operations ($8 million income); and Corporate ($1 million).

•	For the first six months of 2017, IH ($1 million income); EH ($11 million income); WRD/GPD ($26 million income); manufacturing operations ($9 million); and Corporate ($3 million).

(b)	Transaction costs represent external costs for banking, legal, accounting and other similar services, virtually all of which for the second quarter and first six months of 2017 were directly related to our acquisition of Medivation.

(c)

Integration costs represent external, incremental costs directly related to integrating acquired businesses, and primarily include expenditures for consulting and the integration of systems and processes. In the second quarter and first six months of 2018, integration costs were primarily related to our acquisition of Hospira. In the second quarter and first six months of 2017, integration costs were primarily related to our acquisitions of Hospira and Medivation, including a net gain of $12 million related to the settlement of the Hospira U.S. qualified defined benefit pension plan (see Note 10).

(d)

In the three and six months ended July 1, 2018, primarily represents the net pension curtailments and settlements included in Other (income)/deductions––net upon the adoption of a new accounting standard in the first quarter of 2018. In the three and six months ended July 2, 2017, primarily represents the net pension curtailments and settlements, partially offset by net periodic benefit credits, excluding service costs, related to our acquisition of Hospira, both of which were reclassified to Other (income)/deductions––net as a result of the retrospective adoption of a new accounting standard in the first quarter of 2018. These credits included a net settlement gain, partially offset by accelerated amortization of actuarial losses and prior service costs upon the settlement of the remaining obligation associated with the Hospira U.S. qualified defined benefit pension plan. For additional information, see Note 1B and Note 10.

(e)	Additional depreciation––asset restructuring represents the impact of changes in the estimated useful lives of assets involved in restructuring actions.

(f)	Implementation costs represent external, incremental costs directly related to implementing our non-acquisition-related cost-reduction/productivity initiatives.

(a)	Included in Other current liabilities ($643 million) and Other noncurrent liabilities ($462 million).

(b)	Includes adjustments for foreign currency translation.

(c)	Included in Other current liabilities ($460 million) and Other noncurrent liabilities ($418 million).

(a)	Interest income decreased in the second quarter and first six months of 2018, primarily driven by a lower investment balance. Interest expense increased in the second quarter and first six months of 2018, primarily as a result of higher short-term interest rates, offset, in part, by refinancing activity that occurred in the fourth quarter of 2017.

(b)

In the second quarter of 2018, primarily includes gains on fixed assets and other asset disposals of $15 million. In the first six months of 2018, includes gains on fixed assets and other asset disposals of $22 million and net gains on sales of investments in equity and debt securities of approximately $14 million. In the second quarter of 2017, primarily includes gains on sales and redemptions of investments in equity and debt securities (approximately $60 million), partially offset by a net loss related to the sale of our 40% ownership investment in Teuto, including the extinguishment of a put option for the then remaining 60% ownership interest (approximately $30 million). In the first six months of 2017, primarily includes gains on sales and redemptions of investments in equity and debt securities (approximately $102 million) and a gain on sale of property (approximately $50 million), partially offset by the net loss related to the sale of our investment in Teuto discussed above.

(c)

Includes income from upfront and milestone payments from our collaboration partners and income from out-licensing arrangements and sales of compound/product rights. In the second quarter of 2018, primarily includes, among other things, approximately $88 million in milestone income from multiple licensees and an upfront payment to us of $75 million for the sale of an AMPA receptor potentiator for CIAS to Biogen. In the first six months of 2018, primarily includes, among other things, all of the factors discussed above for the second quarter of 2018, as well as a $75 million milestone payment received from Shire related to their first dosing of a patient in a Phase 3 clinical trial of a compound out-licensed by Pfizer to Shire for the treatment of ulcerative colitis, and a $40 million milestone payment from Merck in conjunction with the approval of ertugliflozin in the EU. For additional information, see Note 2B, Note 2C and Note 2D.

(d)

Represents the unrealized net gains on equity securities reflecting the adoption of a new accounting standard in the first quarter of 2018. Approximately $142 million of these unrealized gains in the second quarter of 2018 and approximately $203 million of these unrealized gains in the first six months of 2018 relate to 3.2 million shares of ICU Medical stock that were received as part of the consideration for the sale of HIS net assets to ICU Medical. Prior to the

---

(e)

Represents the net periodic benefit costs/(credits), excluding service costs, as a result of the adoption of a new accounting standard in the first quarter of 2018. Effective January 1, 2018, the U.S. Pfizer Consolidated Pension Plan was frozen to future benefit accruals and for the second quarter and first six months of 2018, resulted in the recognition of lower net periodic benefit costs due to the extension of the amortization period for the actuarial losses and the elimination of service costs. There was also a greater than expected gain on plan assets due to a higher plan asset base compared to the second quarter and first six months of 2017. For additional information, see Note 1B and Note 10.

(f)	In the second quarter and first six months of 2018, primarily represents the reversal of a legal accrual where a loss was no longer deemed probable.

(g)

In the second quarter and first six months of 2018, includes an intangible asset impairment charge related to a finite-lived developed technology right, acquired in connection with our acquisition of Anacor, for the treatment for toenail fungus marketed in the U.S. market only. The impairment charge for the second quarter and first six months of 2018 is associated with IH and reflects, among other things, updated commercial forecasts.

(h)	In the second quarter and first six months of 2018 and 2017, represents adjustments to amounts previously recorded in 2016 to write down the HIS net assets to fair value less costs to sell related to the sale of HIS net assets to ICU Medical on February 3, 2017. For additional information, see Note 2B.

(i)	In the second quarter and first six months of 2018 and 2017, represents expenses for changes to our infrastructure to align our commercial operations of our current segments, including costs to internally separate our businesses into distinct legal entities, as well as to streamline our intercompany supply operations to better support each business.

(j)

In the second quarter and first six months of 2018, includes, among other things, dividend income of $76 million and $135 million, respectively, from our investment in ViiV, and charges of $23 million and $135 million, respectively, reflecting the change in the fair value of contingent consideration. The second quarter and first six months of 2018 also include a non-cash $50 million pre-tax gain on the contribution of Pfizer’s allogeneic CAR T therapy development program assets obtained from Cellectis and Servier in connection with our contribution agreement entered into with Allogene in which Pfizer obtained a 25% ownership stake in Allogene (see Note 2B), and a non-cash $17 million pre-tax gain on the cash settlement of a liability that we incurred in April 2018 upon the EU approval of Mylotarg (see Note 7E). In the second quarter and first six months of 2017, primarily includes, among other things, dividend income of $114 million and $157 million, respectively, from our investment in ViiV.

(a)	The fair value amount is presented as of the date of impairment, as these assets are not measured at fair value on a recurring basis.

(b)

Reflects intangible assets written down to fair value in the second quarter and first six months of 2018. Fair value was determined using the income approach, specifically the multi-period excess earnings method, also known as the discounted cash flow method. We started with a forecast of all the expected net cash flows associated with the asset and then applied an asset-specific discount rate to arrive at a net present value amount. Some of the more significant estimates and assumptions inherent in this approach include: the amount and timing of the projected net cash flows, which includes the expected impact of competitive, legal and/or regulatory forces on the product; the discount rate, which seeks to reflect the various risks inherent in the projected cash flows; and the tax rate, which seeks to incorporate the geographic diversity of the projected cash flows.

Generally, we recognize the gains and losses on foreign exchange contracts that are designated as fair value hedges in earnings upon the recognition of the change in fair value of the hedged risk. Upon the adoption of the new standard in 2018, for certain foreign exchange contracts, we exclude an amount from the assessment of hedge effectiveness and recognize that excluded amount through an amortization approach. We also recognize the offsetting foreign exchange impact attributable to the hedged item in earnings.

•

Generally, we record in Other comprehensive income/(loss) gains or losses on foreign exchange contracts that are designated as cash flow hedges and reclassify those amounts, as appropriate, into earnings in the same period or periods during which the hedged transaction affects earnings. Upon the adoption of the new standard in 2018, for certain foreign exchange contracts, we exclude an amount from the assessment of hedge effectiveness and recognize that excluded amount through an amortization approach.

•

Historically, as part of our net investment hedging program, we recognize the gain and loss impact on foreign exchange contracts designated as hedges of our net investments in earnings in three ways: over time––for the periodic net swap payments; immediately––to the extent of any change in the difference between the foreign exchange spot rate and forward rate; and upon sale or substantial liquidation of our net investments––to the extent of change in the foreign exchange spot rates. Upon the adoption of the new standard in 2018, for foreign exchange contracts, we exclude an amount from the assessment of hedge effectiveness and recognize that excluded amount through an amortization approach. We record in Other comprehensive income/(loss) the foreign exchange gains and losses related to foreign exchange-denominated debt designated as a hedge of our net investments in foreign subsidiaries and reclassify those amounts into earnings upon the sale or substantial liquidation of our net investments.

•

For certain foreign exchange contracts not designated as hedging instruments, we recognize the gains and losses on foreign currency exchange contracts that are used to offset the same foreign currency assets or liabilities immediately into earnings along with the earnings impact of the items they generally offset. These contracts essentially take the opposite currency position of that reflected in the month-end balance sheet to counterbalance the effect of any currency movement.

•	We recognize the gains and losses on interest rate contracts that are designated as fair value hedges in earnings upon the recognition of the change in fair value of the hedged risk. We also recognize the offsetting earnings impact of fixed-rate debt attributable to the hedged risk in earnings.

For derivative financial instruments in cash flow hedge relationships, the gains and losses are included in Other comprehensive income/(loss)––Unrealized holding gains/(losses) on derivative financial instruments, net. For derivative financial instruments in net investment hedge relationships and for foreign currency debt designated as hedging instruments, the effective portion is included in Other comprehensive income/(loss)––Foreign currency translation adjustments, net.

(d)	Based on quarter-end foreign exchange rates that are subject to change, we expect to reclassify a pre-tax gain of $55 million within the next 12 months into Cost of sales. The maximum length of time over which we are hedging future foreign exchange cash flow relates to our $1.8 billion U.K. pound debt maturing in 2043.

In the second quarter of 2017, we settled the remaining obligation associated with the Hospira U.S. qualified defined benefit pension plan. We purchased a group annuity contract on behalf of the remaining plan participants with a third-party insurance provider. As a result, we were relieved of the $156 million net pension benefit obligation and recorded a pre-tax settlement gain of $41 million, partially offset by the recognition of actuarial losses and prior service costs upon plan settlement of approximately $30 million in Other (income)/deductions––net (see Note 3).

(b)	We adopted a new accounting standard on January 1, 2018 that requires the net periodic pension and postretirement benefit costs other than service costs be presented in Other (income)/deductions––net on the condensed consolidated statements of income. For additional information, see Note 1B and Note 4.

(c)

Effective January 1, 2018, we froze two significant defined benefit pension plans to future benefit accruals in the U.S. and U.K. and as a result, service costs for those plans are eliminated. In addition, due to the plan freeze, the average amortization period for the U.S. qualified plans and U.S. supplemental (non-qualified) plans was extended to the expected life expectancy of the plan participants, whereas the average amortization period in prior years utilized the expected future service period of plan participants.

Accelerated share repurchase agreement––On March 12, 2018, we entered into an accelerated share repurchase agreement with Citibank to repurchase $4.0 billion of our common stock. Pursuant to the terms of the agreement, on March 14, 2018, we paid $4.0 billion to Citibank and received an initial delivery of approximately 87 million shares of our common stock from Citibank at a price of $36.61 per share, which represented, based on the closing price of our common stock on the NYSE on March 12, 2018, approximately 80% of the notional amount of the accelerated share repurchase agreement. As of July 1, 2018, the common stock received is included in Treasury stock. At settlement of the agreement, which is expected to occur during the third quarter of 2018, Citibank may be required to deliver additional shares of common stock to us, or, under certain circumstances, we may be required to deliver shares of our common stock or may elect to make a cash payment to Citibank, with the number of shares to be delivered or the amount of such payment, as well as the final average price per share, based on the difference between the volume-weighted average price, less a discount, of Pfizer’s common stock during

Governments, corporations, and insurance companies, which provide insurance benefits to patients, have implemented increases in cost-sharing and restrictions on access to medicines, potentially causing patients to switch to generic or biosimilar products, delay treatments, skip doses or use less effective treatments. Government financing pressures can lead to negative pricing pressure in various markets where governments take an active role in setting prices, access criteria (e.g., through public or private health technology assessments), or other means of cost control. Examples include Europe, Japan, China, Canada, South Korea and a number of other international markets. The U.S. continues to maintain competitive insurance markets, but has also seen significant increases in patient cost-sharing and growing government influence as government programs continue to grow as a source of coverage.

Significant portions of our revenues, costs and expenses, as well as our substantial international net assets, are exposed to changes in foreign exchange rates. We seek to manage our foreign exchange risk in part through operational means, including managing same-currency revenues in relation to same-currency costs and same-currency assets in relation to same-currency liabilities. Depending on market conditions, foreign exchange risk also is managed through the use of derivative financial instruments and foreign currency debt. As we operate in multiple foreign currencies, including the euro, the Japanese yen, the Chinese renminbi, the U.K. pound, the Canadian dollar and approximately 100 other currencies, changes in those currencies relative to the U.S. dollar will impact our revenues and expenses. If the U.S. dollar were to weaken against another currency, assuming all other variables remained constant, our revenues would increase, having a positive impact on earnings, and our overall expenses would increase, having a negative impact on earnings. Conversely, if the U.S. dollar were to strengthen against another currency, assuming all other variables remained constant, our revenues would decrease, having a negative impact on earnings, and our overall expenses would decrease, having a positive impact on earnings. Therefore, significant changes in foreign exchange rates can impact our results and our financial guidance.

In June 2016, the U.K. electorate voted in a referendum to leave the EU, which is commonly referred to as “Brexit”. In March 2017, the U.K. government formally notified the European Council of its intention to leave the EU after it triggered Article 50 of the Lisbon Treaty to begin the two-year negotiation process establishing the terms of the exit and outlining the future relationship between the U.K. and the EU. Formal negotiations officially started in June 2017. This process continues to be highly complex and the end result of these negotiations may pose certain implications to our research, commercial and general business operations in the U.K. and the EU, including the approval and supply of our products. The EMA announced in November 2017 that it will be relocating from London, U.K. to Amsterdam, Netherlands by the expected date of Brexit in March 2019.

On December 22, 2017, the U.S. enacted significant changes to U.S. tax law following the passage and signing of the TCJA. The TCJA is complex and significantly changes the U.S. corporate income tax system by, among other things, reducing the U.S. Federal corporate tax rate from 35% to 21%, transitioning U.S. international taxation from a worldwide tax system to a territorial tax system and imposing a repatriation tax on deemed repatriated accumulated post-1986 earnings of foreign subsidiaries. Given the significant changes resulting from and complexities associated with the TCJA, the estimated financial impacts for 2017, as well as the estimated impact on 2018 financial guidance for the effective tax rate on adjusted income are provisional and subject to further analysis, interpretation and clarification of the TCJA, which could result in changes to these estimates during 2018. For additional information, see the “Our Financial Guidance for 2018”, “Provision for Taxes on Income” and “Analysis of Financial Condition, Liquidity and Capital Resources” sections of this MD&A and Notes to Condensed Consolidated Financial Statements––Note 5A.

Sale of Hospira Infusion Systems Net Assets to ICU Medical, Inc. (EH)––On February 3, 2017, we completed the sale of our global infusion systems net assets, HIS, to ICU Medical. In connection with this transaction, we recognized pre-tax income of approximately $2 million in the second quarter of 2018 and a pre-tax loss of approximately $1 million in the first six months of 2018, and we recognized pre-tax losses of approximately $28 million and $64 million in the second quarter and first six months of 2017, respectively, in Other (income)/deductions––net, representing adjustments to amounts previously recorded in 2016 to write down the HIS net assets to fair value less costs to sell. We may record additional adjustments to the loss on the sale of HIS net assets in future periods, which we do not expect to have a material impact on our consolidated financial statements.

Research and Development Arrangement with NovaQuest Co-Investment Fund V, L.P.––In April 2016, Pfizer entered into an agreement with NovaQuest under which NovaQuest will fund up to $200 million in development costs related to certain Phase 3 clinical trials of Pfizer’s rivipansel compound and Pfizer will use commercially reasonable efforts to develop and obtain regulatory approvals for such compound. NovaQuest’s development funding is expected to cover up to 100% of the development costs and will be received over approximately 12 quarters from 2016 to 2019. As there is a substantive and genuine transfer of risk to NovaQuest, the development funding is recognized by us as an obligation to perform contractual services and therefore is a reduction of Research and development expenses as incurred. The reduction to Research and development expenses for the second quarter of 2018 totaled $16.9 million and for the first six months of 2018 totaled $31.3 million. The reduction to Research and development expenses for the second quarter of 2017 totaled $14.8 million and for the first six months of 2017 totaled $32.0 million. Following potential regulatory approval, NovaQuest will be eligible to receive a combination of fixed milestone payments of up to approximately $267 million in total, based on achievement of first commercial sale and certain levels of cumulative net sales as well as royalties on rivipansel net sales over approximately eight years. Fixed sales-based milestone payments will be recorded as intangible assets and amortized to Amortization of intangible assets over the estimated commercial life of the rivipansel product and royalties on net sales will be recorded as Cost of sales when incurred.

•	Revenue guidance was updated solely to reflect recent unfavorable changes in foreign exchange rates in relation to the U.S. dollar from mid-April 2018 to mid-July 2018, primarily the weakening of the euro, Chinese yuan and Japanese yen.

•	Guidance for Adjusted R&D expenses was updated primarily to reflect higher anticipated spend in the second half of 2018 than previously projected, largely related to our late-stage development programs.

•	Guidance for Adjusted other (income)/deductions was updated primarily to reflect unrealized net gains on equity securities, one-time milestone payments from certain collaborations and out-licensing arrangements and a gain on the sale of certain compound/product rights in the first-half of 2018.

•	Guidance for the effective tax rate on Adjusted income was updated primarily to reflect our evolving understanding of the impact of the TCJA on our business. Although these estimates continue to be subject to further analysis, interpretation and clarification of the TCJA, our current expectation is that this revised tax rate guidance will be sustainable beyond 2018.

(a)	The 2018 financial guidance reflects the following:

•	A full year contribution from Consumer Healthcare. Pfizer continues to expect that any decision regarding strategic alternatives for Consumer Healthcare would be made during 2018.

•	Does not assume the completion of any business development transactions not completed as of July 1, 2018, including any one-time upfront payments associated with such transactions.

•

Guidance for Adjusted other (income)/deductions does not attempt to forecast unrealized net gains or losses on equity securities. Pfizer is unable to predict with reasonable certainty unrealized gains or losses on equity securities in a given period. Net unrealized gains and losses on equity securities are now recorded in Adjusted other (income)/deductions during each quarter, reflecting the adoption of a new accounting standard in the first quarter of 2018 (see Notes to Condensed Consolidated Financial Statements—Note 1B. Basis of Presentation and Significant Accounting Policies: Adoption of New Accounting Standards). Prior to the adoption of the new standard, net unrealized gains and losses on virtually all equity securities with readily determinable fair values were reported in Accumulated other comprehensive income.

•	Exchange rates assumed are a blend of the actual exchange rates in effect through second-quarter 2018 and mid-July 2018 exchange rates for the remainder of the year.

Reflects an anticipated negative revenue impact of $1.9 billion due to recent and expected generic and biosimilar competition for certain products that have recently lost or are anticipated to soon lose patent protection. Assumes no generic competition for Lyrica in the U.S. until June 2019, which is contingent upon a six-month patent-term extension granted by the FDA for pediatric exclusivity, which the company is currently pursuing.

•	Reflects the anticipated favorable impact of approximately $500 million on revenues and approximately $0.03 on adjusted diluted EPS as a result of favorable changes in foreign exchange rates relative to the U.S. dollar compared to foreign exchange rates from 2017.

•	Guidance for adjusted diluted EPS assumes diluted weighted-average shares outstanding of approximately 6.0 billion shares, which reflects share repurchases totaling approximately $6.1 billion already completed in 2018. Dilution related to share-based employee compensation programs is expected to offset by approximately half the reduction in shares associated with these share repurchases.

(b)

The effective tax rate on Non-GAAP Adjusted income was 15.8% in the second quarter of 2018, compared with 22.9% in the second quarter of 2017. The effective tax rate on Non-GAAP Adjusted income was 16.1% in the first six months of 2018, compared with 22.6% in the first six months of 2017. The decreases were primarily due to tax benefits associated with the December 2017 enactment of the TCJA, a favorable change in the jurisdictional mix of earnings as a result of operating fluctuations in the normal course of business, as well as an increase in benefits associated with the resolution of certain tax positions pertaining to prior years primarily with various foreign authorities, and the expiration of certain statutes of limitations.

The six months ended July 1, 2018 were favorably impacted by the December 2017 enactment of the TCJA, primarily related to certain tax initiatives associated with the lower U.S. tax rate as a result of the TCJA. Given the significant changes resulting from and complexities associated with the TCJA, the estimated financial impacts recorded in 2017 are provisional and are subject to further analysis, interpretation and clarification of the TCJA, which could result in changes to these estimates during 2018. Under guidance issued by the staff of the SEC, we expect to finalize our accounting related to the tax effects of the TCJA on deferred taxes, valuation allowances, state tax considerations, the repatriation tax liability, global intangible low-taxed income, and any remaining outside basis differences in our foreign subsidiaries during 2018 as we complete our analysis, computations and assertions. It is possible that others, applying reasonable judgment to the same facts and circumstances, could develop and support a range of alternative estimated amounts. We will revise these estimates during the second half of 2018 as we gather additional information to complete our tax returns and as any interpretation or clarification of the TCJA occurs through legislation, U.S. Treasury actions or other means.

*	Indicates calculation not meaningful or result is equal to or greater than 100%.

(a)	Amounts represent the revenues and costs managed by each of our operating segments. The expenses generally include only those costs directly attributable to the operating segment.

(b)	Other comprises the costs included in our Adjusted income components (see footnote (c) below) that are managed outside of our two operating segments and includes the following:

---

(i)

WRD—the R&D expenses managed by our WRD organization, which is generally responsible for research projects for our IH business until proof-of-concept is achieved and then for transitioning those projects to the IH segment via the GPD organization for possible clinical and commercial development. R&D spending may include upfront and milestone payments for intellectual property rights. The WRD organization also has responsibility for certain science-based and other platform-services organizations, which provide technical expertise and other services to the various R&D projects, including EH R&D projects. WRD is also responsible for facilitating all regulatory submissions and interactions with regulatory agencies, including all safety-event activities.

(ii)	GPD––the costs associated with our GPD organization, which is generally responsible for the clinical development of assets that are in clinical trials for our WRD and Innovative portfolios. GPD also provides technical support and other services to Pfizer R&D projects.

(iii)

Corporate––the costs associated with Corporate, representing platform functions (such as worldwide technology, global real estate operations, legal, finance, human resources, worldwide public affairs, compliance and worldwide procurement), the provision of medical information to healthcare providers, patients and other parties, transparency and disclosure activities, clinical trial results publication, grants for healthcare quality improvement and medical education, and partnerships with global public health and medical associations, as well as certain compensation and other corporate costs, such as interest income and expense, and gains and losses on investments. Effective in the first quarter of 2018, certain costs for StratCO, which were previously reported in the operating results of our operating segments and Corporate, are reported in Other Unallocated. For additional information, see note (iv) below.

(iv)

Other Unallocated—other unallocated costs, representing overhead expenses associated with our manufacturing and commercial operations that are not directly assessed to an operating segment, as business unit (segment) management does not manage these costs (which include manufacturing variances associated with production). In connection with the StratCO reporting change, in the second quarter of 2017, we reclassified approximately $120 million of costs from IH, approximately $45 million of costs from EH and approximately $12 million of costs from Corporate to Other unallocated costs to conform to the current period presentation. In the first six months of 2017, we reclassified approximately $218 million of costs from IH, approximately $78 million of costs from EH and approximately $21 million of costs from Corporate to Other unallocated costs to conform to the current period presentation.

(i)	Amount represents the revenues and costs managed by each of our operating segments. The expenses generally include only those costs directly attributable to the operating segment. See note (a) above for more information.

(ii)	Represents costs not assessed to an operating segment, as business unit (segment) management does not manage these costs. For a description of these other costs and business activities, see note (b) above.

•	WRD/GPD––The information provided for WRD and GPD was substantially all derived from our estimates of the costs incurred in connection with the R&D projects associated with each operating segment.

•

Corporate/Other Unallocated––The information provided for Corporate and Other Unallocated was derived mainly using proportional allocation methods based on global, regional or country revenues or global, regional or country headcount, as well as certain cost metrics, as appropriate, such as those derived from research and development and manufacturing costs, and, to a lesser extent, specific identification and estimates. Management believes that the allocations of Corporate and Other Unallocated costs are reasonable.

Both Moody’s and S&P rating agencies maintained our strong investment-grade corporate debt rating subsequent to the acquisitions of Medivation and Anacor. For additional information, see the “Credit Ratings” section of this MD&A.

•	an increase in short-term borrowings as a result of issuance of commercial paper; and
