Schedule of New Accounting Pronouncements and Changes in Accounting Principles [Table Text Block] | 3. Recent Accounting Pronouncements In January 2013, the Financial Accounting Standard Board (“FASB”) issued ASU 2013-01, “Balance Sheet (Topic 210): Clarifying the Scope of Disclosures about Offsetting Assets and Liabilities.” ASU No. 2013-01 clarifies that the scope of Update 2011-11 applies to derivatives, repurchase agreements, and securities lending transactions to the extent that they are either offset in the financial statements or subject to an enforceable master netting arrangement or similar agreement. ASU 2013-01 became effective for interim and annual periods beginning on or after January 1, 2013. Adoption of ASU 2013-01 did not have a significant impact on the Company’s consolidated financial statements. See Note 15 to the Company’s consolidated financial statements for the disclosure of adoption of ASU 2013-01. In February 2013, the FASB issued ASU 2013-02 “Reporting of Amounts Reclassified Out of Accumulated Other Comprehensive Income.” ASU 2013-02 amends Topic 220, “Comprehensive Income,” to improve the reporting of reclassification out of accumulated other comprehensive income. The amendments do not change the current requirements for reporting net income or other comprehensive income in financial statements. However, the amendments require an entity to provide information about the amounts reclassified and to present significant amounts reclassified out of accumulated other comprehensive income by the respective line items of net income. ASU 2013-02 became effective prospectively for reporting periods beginning after December 15, 2012. Adoption of ASU 2013-02 did not have a significant impact on the Company’s consolidated financial statements. See Note 16 to the Company’s condensed consolidated financial statements for the disclosure of adoption of ASU 2013-02.
