New accounting pronouncements [Abstract]
Description of New Accounting Pronouncements Not yet Adopted [Text Block]	New accounting pronouncements In September 2011, the FASB issued new accounting guidance related to testing goodwill for impairment. The new guidance allows an entity the option to make a qualitative evaluation about the likelihood of goodwill impairment to determine whether the entity should calculate the fair value of a reporting unit. It also expands the events and circumstances that an entity should consider between annual impairment tests in determining whether it is more likely than not that the fair value of a reporting unit is less than its carrying value. This guidance is effective for annual and interim goodwill impairment tests performed for fiscal years beginning after December 15, 2011. The Company is currently assessing the viability of using a qualitative evaluation to determine whether a fair value should be calculated for certain reporting units.
