| Goodwill and Intangible Assets Disclosure [Text Block] | 4.                    GOODWILL AND INTANGIBLE        ASSETSThe carrying        amount of goodwill is not amortized but subject to annual        impairment testing at the reporting unit level. We evaluate        goodwill for impairment on October 1, or more frequently if        impairment indicators are present. Impairment is the        condition that exists when the carrying amount of goodwill        exceed its implied fair value. The first step in the        impairment process is to determine the fair value of the        reporting unit and then compare it to the carrying value,        including goodwill. We determined that the market        capitalization approach is the most appropriate method of        measuring fair value of the reporting unit, assuming a        controlling interest. Under this approach, fair value is        calculated based on the market price of common stock,        multiplied by the number of outstanding shares. A control        premium, which is representative of premiums paid in the        marketplace to acquire a controlling interest in a company,        is then added to the market capitalization to determine the        fair value of the reporting unit. If the fair value exceeds        the carrying value, no further action is required and no        impairment loss is recognized. We monitor changes in our        closing market price and its effect on fair value and the        relationship to the carrying value. Additional impairment        assessments may be performed on an interim basis if we        encounter events or changes in circumstances that would        indicate that, more likely than not, the carrying value of        goodwill has been impaired. At December 31, 2011, the        Company did not identify any potential impairment related        to its goodwill.The components        and estimated useful lives of intangible assets as of        December 31, 2011 and 2010 are stated below.
