| Adopted Accounting Updates, Policy | ASU 2013-02, Reporting of Amounts Reclassified Out of Accumulated Other Comprehensive Income  In February 2013, the Financial Accounting Standards Board issued Accounting Standards Update (ASU) 2013-02, Reporting of Amounts Reclassified Out of Accumulated Other Comprehensive Income. ASU 2013-02 requires entities to present in either a single note or parenthetically on the face of the financial statements, the effect of significant amounts reclassified from each component of accumulated other comprehensive income based on its source and the income statement line items affected by the reclassification. The company adopted this ASU during the first quarter of 2013, and it did not have a material impact on our company’s financial position, cash flows or results of operations. See Note 7, Accumulated Other Comprehensive Income, for further details.   |
