Subsequent events [Abstract]
Subsequent events	Note 21 — Subsequent events On December 9, 2011 we entered into a $500,000 unsecured multicurrency credit facility with a group of banks. This facility has a five-year term and includes a $40,000 subfacility for swing-line loans. It may be increased from $500,000 to $750,000 under certain conditions. The new facility contains customary events of default and covenants related to limitations on indebtedness and the maintenance of certain financial ratios. It replaced our existing revolving loan agreement that was scheduled to expire in 2012. Balances outstanding under the prior facility were transferred to the new facility.

Describes disclosed significant events or transactions that occurred after the balance sheet date, but before the issuance of the financial statements. Examples include: the sale of a capital stock issue, purchase of a business, settlement of litigation, losses resulting from fire or flood, losses on receivables, significant realized and unrealized gains and losses that result from changes in quoted market prices of securities, declines in market prices of inventory, changes in authorized or issued debt (SEC), significant foreign exchange rate changes, substantial loans to insiders or affiliates, significant long-term investments, and substantial dividends not in the ordinary course of business.
