Selected Financial Assets and LiabilitiesThe following table provides additional information about certain of our financial assets and liabilities:  As of December 31,(MILLIONS OF DOLLARS) 2012 2011Selected financial assets measured at fair value on a recurring basis(a)    Trading securities(b) $142 $154Available-for-sale debt securities(c) 32,584 29,179Available-for-sale money market funds(d) 1,727 1,727Available-for-sale equity securities, excluding money market funds(c) 263 317Derivative financial instruments in receivable positions:(e)    Interest rate swaps 1,036 1,033Foreign currency forward-exchange contracts 152 349Foreign currency swaps 194 17  36,098 32,776Other selected financial assets    Held-to-maturity debt securities, carried at amortized cost(c), (f) 1,513 1,587Private equity securities, carried at equity method or at cost(f), (g) 1,239 1,020  2,752 2,607Total selected financial assets $38,850 $35,383 Financial liabilities measured at fair value on a recurring basis(a)    Derivative financial instruments in a liability position:(h)    Foreign currency swaps $428 $1,396Foreign currency forward-exchange contracts 243 355Interest rate swaps 33 14  704 1,765Other financial liabilities(i)    Short-term borrowings, carried at historical proceeds, as adjusted(f) 6,424 4,016Long-term debt, carried at historical proceeds, as adjusted(j), (k) 31,036 34,926  37,460 38,942Total selected financial liabilities $38,164 $40,707(a) We use a market approach in valuing financial instruments on a recurring basis. See also Note 1E.Basis of Presentation and Significant Accounting Policies: Fair Value. All of our financial assets and liabilities measured at fair value on a recurring basis use Level 2 inputs in the calculation of fair value, except less than 1% that use Level 1 or Level 3 inputs.(b) Trading securities are held in trust for legacy business acquisition severance benefits.(c) Gross unrealized gains and losses are not significant.(d) Includes $408 million as of December 31, 2012 and $357 million as of December 31, 2011 of money market funds held in trust in connection with the asbestos litigation involving Quigley Company, Inc., a wholly owned subsidiary. As of December 31, 2011, this amount includes approximately $625 million of money market funds that were held in escrow to secure certain of Wyeth’s payment obligations under its 1999 Nationwide Class Action Settlement Agreement, which relates to litigation against Wyeth concerning its former weight-loss products, Redux and Pondimin. The amounts held in escrow at December 31, 2011 were released from restriction during 2012 and classified as part of Short-term investments.(e) Designated as hedging instruments, except for certain contracts used as offsets; namely, foreign currency forward-exchange contracts with fair values of $102 million as of December 31, 2012; and foreign currency forward-exchange contracts with fair values of $169 million and interest rate swaps with fair values of $8 million as of December 31, 2011.(f) The differences between the estimated fair values and carrying values of held to maturity debt securities, private equity securities at cost and short-term borrowings not measured at fair value on a recurring basis were not significant as of December 31, 2012 or December 31, 2011. The fair value measurements of our held-to-maturity debt securities and our short-term borrowings are based on Level 2 inputs, using a market approach. The fair value measurements of our private equity securities at cost are based on Level 3 inputs, using a market approach.(g) Our private equity securities represent investments in the life sciences sector.(h) Designated as hedging instruments, except for certain contracts used as offsets; namely, foreign currency forward-exchange contracts with fair values of $141 million and foreign currency swaps with fair values of $129 million as of December 31, 2012; and foreign currency forward-exchange contracts with fair values of $141 million and foreign currency swaps with fair values of $123 million as of December 31, 2011.(i) Some carrying amounts may include adjustments for discount or premium amortization or for the effect of interest rate swaps designated as hedges.(j) Includes foreign currency debt with fair values of $809 million as of December 31, 2012 and $919 million as of December 31, 2011, which are used as hedging instruments.(k) The fair value of our long-term debt (not including the current portion of long-term debt) is $37.5 billion as of December 31, 2012 and $40.1 billion as of December 31, 2011. The fair value measurements for our long-term debt are based on Level 2 inputs, using a market approach.A single estimate of fair value can result from a complex series of judgments about future events and uncertainties and can rely heavily on estimates and assumptions. For a description of our general accounting policies associated with developing fair value estimates, see Note 1E. Basis of Presentation and Significant Accounting Policies: Fair Value. For a description of the risks associated with estimates and assumptions, see Note 1C. Basis of Presentation and Significant Accounting Policies: Estimates and Assumptions.The following methods and assumptions were used to estimate the fair value of our financial assets and liabilities:•Trading equity securities—quoted market prices.•Trading debt securities—observable market interest rates.•Available-for-sale debt securities—third-party matrix-pricing model that uses significant inputs derived from or corroborated by observable market data and credit-adjusted interest rate yield curves.•Available-for-sale money market funds—observable Net Asset Value prices.•Available-for-sale equity securities, excluding money market funds—third-party pricing services that principally use a composite of observable prices.•Derivative financial instruments (assets and liabilities)—third-party matrix-pricing model that uses significant inputs derived from or corroborated by observable market data. Where applicable, these models discount future cash flow amounts using market-based observable inputs, including interest rate yield curves, and forward and spot prices for currencies. The credit risk impact to our derivative financial instruments was not significant.•Held-to-maturity debt securities—third-party matrix-pricing model that uses significant inputs derived from or corroborated by observable market data and credit-adjusted interest rate yield curves.•Private equity securities, excluding equity-method investments—application of the implied volatility associated with an observable biotech index to the carrying amount of our portfolio.•Short-term borrowings and long-term debt—third-party matrix-pricing model that uses significant inputs derived from or corroborated by observable market data and our own credit rating.We periodically review the methodologies, inputs and outputs of third-party pricing services for reasonableness. Our procedures can include, for example, referencing other third-party pricing models, monitoring key observable inputs (like LIBOR interest rates) and selectively performing test-comparisons of values with actual sales of financial instruments.The following table provides the classification of these selected financial assets and liabilities in our consolidated balance sheets:  As of December 31,(MILLIONS OF DOLLARS) 2012 2011Assets    Cash and cash equivalents $1,000 $900Short-term investments 22,319 23,270Long-term investments 14,149 9,814Taxes and other current assets(a) 296 357Taxes and other noncurrent assets(b) 1,086 1,042  $38,850 $35,383Liabilities    Short-term borrowings, including current portion of long-term debt $6,424 $4,016Other current liabilities(c) 330 459Long-term debt 31,036 34,926Other noncurrent liabilities(d) 374 1,306  $38,164 $40,707(a) As of December 31, 2012, derivative instruments at fair value include foreign currency forward-exchange contracts ($152 million) and foreign currency swaps ($144 million) and, as of December 31, 2011, include foreign currency forward-exchange contracts ($349 million) and interest rate swaps ($8 million).(b) As of December 31, 2012, derivative instruments at fair value include interest rate swaps ($1 billion) and foreign currency swaps ($50 million) and, as of December 31, 2011, include interest rate swaps ($1 billion) and foreign currency swaps ($17 million).(c) At December 31, 2012, derivative instruments at fair value include foreign currency forward-exchange contracts ($243 million) and foreign currency swaps ($87 million) and, as of December 31, 2011, include foreign currency forward-exchange contracts ($355 million) and foreign currency swaps ($104 million).(d) At December 31, 2012, derivative instruments at fair value include foreign currency swaps ($341 million) and interest rate swaps ($33 million) and, as of December 31, 2011, include foreign currency swaps ($1.3 billion) and interest rate swaps ($14 million).In addition, we have long-term receivables where the determination of fair value employs discounted future cash flows, using current interest rates at which similar loans would be made to borrowers with similar credit ratings and for the same remaining maturities. The differences between the estimated fair values and carrying values of these receivables were not significant as of December 31, 2012 or December 31, 2011. There were no significant impairments of financial assets recognized in any period presented.B.

Derivative Financial Instruments and Hedging ActivitiesForeign Exchange RiskA significant portion of our revenues, earnings and net investments in foreign affiliates is 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. These financial instruments serve to protect net income and net investments against the impact of the translation into U.S. dollars of certain foreign exchange-denominated transactions. As of December 31, 2012, the aggregate notional amount of foreign exchange derivative financial instruments hedging or offsetting foreign currency exposures is $45.6 billion. The derivative financial instruments primarily hedge or offset exposures in the euro, Japanese yen and U.K. pound. The maximum length of time over which we are hedging future foreign exchange cash flow relates to our $2.4 billion U.K. pound debt maturing in 2038.All derivative contracts used to manage foreign currency risk are measured at fair value and are reported as assets or liabilities on the consolidated balance sheet. Changes in fair value are reported in earnings or in Other comprehensive income/(loss), depending on the nature and purpose of the financial instrument (offset or hedge relationship) and the effectiveness of the hedge relationships, as follows:•We record in Other comprehensive income/(loss) the effective portion of the gains or losses on foreign currency forward-exchange contracts and foreign currency swaps 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.•We recognize the gains and losses on forward-exchange contracts and foreign currency swaps 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 gain and loss impact on foreign currency swaps 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.•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.Any ineffectiveness is recognized immediately into earnings. There was no significant ineffectiveness for any period presented.Interest Rate Risk Our interest-bearing investments, loans and borrowings are subject to interest rate risk. We seek to invest and loan primarily on a short-term or variable-rate basis; however, in light of current market conditions, we currently borrow primarily on a long-term, fixed-rate basis. From time to time, depending on market conditions, we will change the profile of our outstanding debt by entering into derivative financial instruments like interest rate swaps.We entered into derivative financial instruments to hedge or offset the fixed interest rates on the hedged item, matching the amount and timing of the hedged item. As of December 31, 2012, the aggregate notional amount of interest rate derivative financial instruments is $11.6 billion. The derivative financial instruments primarily hedge U.S. dollar and euro fixed-rate debt.All derivative contracts used to manage interest rate risk are measured at fair value and reported as assets or liabilities on the consolidated balance sheet. Changes in fair value are reported in earnings, as follows:•We recognize the gains and losses on interest rate swaps that are designated as fair value hedges in earnings upon the recognition of the change in fair value of the hedged risk. We recognize the offsetting earnings impact of fixed-rate debt attributable to the hedged risk also in earnings.Any ineffectiveness is recognized immediately into earnings. There was no significant ineffectiveness for any period presented.The following table provides information about the gains/(losses) incurred to hedge or offset operational foreign exchange or interest rate risk:  Amount ofGains/(Losses)Recognized in OID(a), (b), (c) Amount ofGains/(Losses)Recognized in OCL(Effective Portion)(a), (d) Amount ofGains/(Losses)Reclassified fromOCL into OID(Effective Portion)(a), (d)(MILLIONS OF DOLLARS) Dec 31, 2012 Dec 31, 2011 Dec 31, 2012 Dec 31, 2011 Dec 31, 2012 Dec 31, 2011Derivative Financial Instruments in Cash Flow Hedge Relationships:            Foreign currency swaps $— $— $676 $(496) $257 $(243)             Derivative Financial Instruments in Net Investment Hedge Relationships:            Foreign currency swaps (4) 7 200 (1,059) — —             Derivative Financial Instruments Not Designated as Hedges:            Foreign currency forward-exchange contracts (61) (260) — — — —Foreign currency swaps (7) 106 — — — —             Non-Derivative Financial Instruments in Net Investment Hedge Relationships:            Foreign currency short-term borrowings — — — 940 — —Foreign currency long-term debt — — 88 (41) — —All other net 7 15 5 (4) 6 4  $(65) $(132) $969 $(660) $263 $(239)(a) OID = Other (income)/deductions—net, included in Other deductions—net in the consolidated statements of income. OCL = Other comprehensive loss, included in the consolidated statements of comprehensive income.(b) Also includes gains and losses attributable to the hedged risk in fair value hedge relationships.(c) There was no significant ineffectiveness for any period presented.(d) Amounts presented represent the effective portion of the gain or loss. For derivative financial instruments in cash flow hedge relationships, the effective portion is included in Other comprehensive loss––Unrealized holding gains/(losses) on derivative financial instruments. 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 loss––foreign currency translation adjustments.For information about the fair value of our derivative financial instruments, and the impact on our consolidated balance sheets, see Note 7A. Financial Instruments: Selected Financial Assets and Liabilities above. Certain of our derivative instruments are covered by associated credit-support agreements that have credit-risk-related contingent features designed to reduce our counterparties’ exposure to our risk of defaulting on amounts owed. As of December 31, 2012, the aggregate fair value of these derivative instruments that are in a net liability position is $451 million, for which we have posted collateral of $424 million in the normal course of business. These features include the requirement to pay additional collateral in the event of a downgrade in our debt ratings. If there had been a downgrade to below an A rating by S&P or the equivalent rating by Moody’s Investors Service, on December 31, 2012, we would have been required to post an additional $58 million of collateral to our counterparties. The collateral advanced receivables are reported in Cash and cash equivalents.F. Credit RiskOn an ongoing basis, we review the creditworthiness of counterparties to our foreign exchange and interest rate agreements and do not expect to incur a significant loss from failure of any counterparties to perform under the agreements. There are no significant concentrations of credit risk related to our financial instruments with any individual counterparty. As of December 31, 2012, we had $2.9 billion due from a well-diversified, highly rated group (S&P ratings of mostly A+ or better) of bank counterparties around the world. See Note 7B. Financial Instruments: Investments in Debt Securities above for details about our investments.In general, there is no requirement for collateral from customers. However, derivative financial instruments are executed under master netting agreements with financial institutions. These agreements contain provisions that provide for the ability for collateral payments, depending on levels of exposure, our credit rating and the credit rating of the counterparty. As of December 31, 2012, we received cash collateral of $660 million against various counterparties. The collateral primarily supports the approximate fair value of our derivative contracts. With respect to the collateral received, which is included in Cash and cash equivalents, the obligations are reported in Short-term borrowings, including current portion of long-term debt. |
