Organization, Consolidation and Presentation of Financial Statements [Abstract]
Income Tax, Policy [Policy Text Block]	Income Taxes In calculating the provision for interim income taxes, in accordance with Accounting Standards Codification (ASC) 740, Income Taxes, we apply an estimated annual effective tax rate to year-to-date ordinary income. At the end of each interim period, we estimate the effective tax rate expected to be applicable for the full fiscal year. We exclude and record discretely the tax effect of unusual or infrequently occurring items, including, for example, changes in judgment about valuation allowances and effects of changes in tax law or rates. The provision for income taxes in tax jurisdictions with a projected full year or year-to-date loss for which a tax benefit cannot be realized is estimated using tax rates specific to that jurisdiction. Refer to Note 1 to the Consolidated Financial Statements in our 2012 Annual Report regarding additional significant accounting policies.
Discontinued Operations, Policy [Policy Text Block]	We classify operations as discontinued when operations and cash flows will be eliminated from our ongoing operations and we do not expect to retain any significant continuing involvement in their operations after the respective sale transactions. For all periods presented, the operating results for these discontinued operations have been removed from continuing operations and presented separately as discontinued operations, net of tax, in the Condensed Consolidated Statement of Comprehensive Income. The Notes to the Condensed Consolidated Financial Statements have been adjusted to exclude discontinued operations unless otherwise noted.

Disclosure of accounting policy for any discontinued operations. The results of operations of a component of an entity that either has been disposed of or is classified as held for sale is reported in discontinued operations if both: (a) the operations and cash flows of the component have been (or will be) eliminated from the ongoing operations of the entity as a result of the disposal transaction and (b) the entity will not have any significant continuing involvement in the operations of the component after the disposal transaction. If the entity elects to allocate interest expense to a discontinued operation, it may disclose its accounting policy for this election and describe its method of allocation.
