Derivative Financial Instruments and Hedging ActivitiesForeign Exchange RiskAs of September 29, 2013, the aggregate notional amount of foreign exchange derivative financial instruments hedging or offsetting foreign currency exposures is $41.7 billion. The derivative financial instruments primarily hedge or offset exposures in the euro, Japanese yen, U.K. pound and Swiss franc. 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. Interest Rate Risk As of September 29, 2013, the aggregate notional amount of interest rate derivative financial instruments is $16.5 billion. The derivative financial instruments primarily hedge U.S. dollar and euro fixed-rate debt.The following table provides information about the gains/(losses) recognized 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 OCI(Effective Portion)(a), (d) Amount ofGains/(Losses)Reclassified fromOCI into OID(Effective Portion)(a), (d)(MILLIONS OF DOLLARS) Sep 29, 2013 Sep 30, 2012 Sep 29, 2013 Sep 30, 2012 Sep 29, 2013 Sep 30, 2012Three Months Ended            Derivative Financial Instruments in Cash Flow Hedge Relationships:            Foreign currency swaps $— $— $489 $455 $313 $221             Derivative Financial Instruments in Net Investment Hedge Relationships:            Foreign currency swaps — — (2) (40) — —Foreign currency forward-exchange contracts (4) — (1) — — —             Derivative Financial Instruments Not Designated as Hedges:            Foreign currency forward-exchange contracts (81) (201) — — — —Foreign currency swaps (15) 10 — — — —             Non-Derivative Financial Instruments in Net Investment Hedge Relationships:            Foreign currency long-term debt — — (4) (20) — —All other net — — 1 — — —  $(100) $(191) $483 $395 $313 $221Nine Months Ended            Derivative Financial Instruments in Cash Flow Hedge Relationships:            Foreign currency swaps $— $— $334 $237 $64 $89             Derivative Financial Instruments in Net Investment Hedge Relationships:            Foreign currency swaps (3) (2) 137 32 — —Foreign currency forward-exchange contracts (4) — (1) — — —             Derivative Financial Instruments Not Designated as Hedges:            Foreign currency forward-exchange contracts 47 (138) — — — —Foreign currency swaps (14) (7) — — — —             Non-Derivative Financial Instruments in Net Investment Hedge Relationships:            Foreign currency long-term debt — — 93 3 — —All other net — 2 2 5 — 5  $26 $(145) $565 $277 $64 $94(a) OID = Other (income)/deductions—net, included in Other (income)/deductions—net in the condensed consolidated statements of income.

For derivative financial instruments in cash flow hedge relationships, the effective portion is included in Other comprehensive income/(loss)––Unrealized holding gains on derivative financial instruments.

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 September 29, 2013, the aggregate fair value of these derivative instruments that are in a net liability position is $250 million, for which we have posted collateral of $221 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 September 29, 2013, we would have been required to post an additional $46 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 September 29, 2013, we had $2.5 billion due from a well-diversified, highly rated group (S&P ratings of mostly A+ or better) of bank counterparties around the world. For details about our investments, see Note 7B. Financial Instruments: Investments in Debt Securities.In general, there is no requirement for collateral from customers. However, derivative financial instruments are executed under master netting agreements with financial institutions and these agreements contain provisions that provide for collateral payments, depending on levels of exposure, our credit rating and the credit rating of the counterparty. For information about our financial instruments (excluding the impact of collateral), see Note 7A. Financial Instruments: Selected Financial Assets and Liabilities and Note 7B. Financial Instruments: Investments in Debt Securities above. For information about the collateral posted on our derivative instruments, see Note 7E. Financial Instruments: Derivative Financial Instruments and Hedging Activities above. As of September 29, 2013, we received cash collateral of $526 million from 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. |
