Long-term debt	$ 2,600,000,000				$ 2,600,000,000

[1] Includes foreign currency debt with fair values of $669 million as of June 29, 2014 and $651 million as of December 31, 2013, which are used as hedging instruments.

[2] Some carrying amounts may include adjustments for discount or premium amortization or for the effect of hedging the interest rate fair value risk associated with certain financial liabilities by interest rate swaps.

[3] The fair value of our long-term debt (not including the current portion of long-term debt) is $37.0 billion as of June 29, 2014 and $35.1 billion as of December 31, 2013. The fair value measurements for our long-term debt are based on Level 2 inputs, using a market approach. Generally, the difference between the fair value of our long-term debt and the amount reported on the condensed consolidated balance sheet is due to a decline in relative market interest rates since the debt issuance.The following table provides the classification of these selected financial assets and liabilities in the condensed consolidated balance sheets:(MILLIONS OF DOLLARS) June 29, 2014 December 31, 2013Assets Cash and cash equivalents $1,430 $1,104Short-term investments 30,648 30,225Long-term investments 17,168 16,406Other current assets(a) 203 286Other noncurrent assets(b) 1,111 1,225 $50,560 $49,246Liabilities Short-term borrowings, including current portion of long-term debt $5,561 $6,027Other current liabilities(c) 215 303Long-term debt 32,267 30,462Other noncurrent liabilities(d) 176 327 $38,219 37,119

[4] OID = Other (income)/deductions—net, included in Other (income)/deductions—net in the condensed consolidated statements of income. OCI = Other comprehensive income/(loss), included in the condensed consolidated statements of comprehensive income

[5] For derivative financial instruments in cash flow hedge relationships, the effective portion is included in Other comprehensive income/(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 income/(loss)––Foreign currency translation adjustments.

[6] Also, includes gains and losses attributable to derivative instruments designated and qualifying as fair value hedges, as well as the offsetting gains and losses attributable to the hedged items in such hedging relationships.

[7] There was no significant ineffectiveness for any period presented.
