Changes in the fair value of a derivative that is qualified, designated and highly effective as a fair value hedge, along with the gain or loss on the hedged asset or liability that is attributable to the hedged risk, are recorded in current earnings. Changes in the fair value of a derivative that is qualified, designated and highly effective as a cash flow hedge are recorded in Accumulated other comprehensive income (loss) (AOCI) in Statement 2 until they are reclassified to earnings in the same period or periods during which the hedged transaction affects earnings.&nbsp;&nbsp;Changes in the fair value of undesignated derivative instruments and the ineffective portion of designated derivative instruments are reported in current earnings. Cash flow from designated derivative financial instruments are classified within the same category as the item being hedged on Statement 4.&nbsp;&nbsp;Cash flow from undesignated derivative financial instruments are included in the investing category on Statement 4.</font></p> <p style="MARGIN: 0in 0in 0pt 0.25in"><font style="FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman" size="2">&nbsp;</font></p> <p style="MARGIN: 0in 0in 0pt 0.25in"><font style="FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman" size="2">We formally document all relationships between hedging instruments and hedged items, as well as the risk-management objective and strategy for undertaking various hedge transactions.&nbsp;&nbsp;This process includes linking all derivatives that are designated as fair value hedges to specific assets and liabilities in Statement 2 and linking cash flow hedges to specific forecasted transactions or variability of cash flow.</font></p> <p style="MARGIN: 0in 0in 0pt"><font style="FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman" size="2">&nbsp;</font></p> <p style="MARGIN: 0in 0in 0pt 0.25in"><font style="FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman" size="2">We also formally assess, both at the hedge&#146;s inception and on an ongoing basis, whether the designated derivatives that are used in hedging transactions are highly effective in offsetting changes in fair values or cash flow of hedged items.&nbsp;&nbsp;When a derivative is determined not to be highly effective as a hedge or the underlying hedged transaction is no longer probable, we discontinue hedge accounting prospectively, in accordance with the derecognition criteria for hedge accounting.</font></p></td></tr></table> Derivative financial instruments and risk management &nbsp; Our earnings and cash flow are subject to fluctuations due to changes in foreign currency exchangefalsefalsefalsefalsefalseOtherus-types:textBlockItemTypestringDescribes the entity's accounting policy with regard to its objectives and strategies pertaining to the use of derivative instruments and nonderivative hedging instruments, in the context of the entity's overall risk management profile, and the risks associated with the use of derivatives.
