[1] OCI is defined as other comprehensive income.

[2] At June 30, 2011, $0.3 of gains associated with the Company's commodity contracts were recorded in Accumulated OCI. The gain will be reclassified from Accumulated OCI into income as a result of inventory being sold.

[3] Each of these derivative instruments has a high correlation to the underlying exposure being hedged and has been deemed highly effective in offsetting associated risk. The ineffective portion recognized in income was insignificant to the quarter and nine months ended June 30, 2011 and 2010.

[4] Gain/(Loss) reclassified to Income was recorded as follows: Foreign currency contracts in other financing, commodity contracts in Cost of products sold.

[5] All derivative assets are presented in other current assets or other assets.

[6] All derivative liabilities are presented in other current liabilities or other liabilities.
