Goodwill and Intangible Assets Disclosure [Abstract]
Goodwill	Goodwill In accordance with US GAAP, the Company tests goodwill for impairment on an annual basis or at an interim period if events or changed circumstances would more likely than not reduce the fair value of a reporting unit below its carrying amount. Under US GAAP, the Company first assesses the qualitative factors to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying amounts as a basis for determining if it is necessary to perform the two-step approach. Periodically estimating the fair value of a reporting unit requires significant judgment and often involves the use of significant estimates and assumptions. These estimates and assumptions could have a significant effect on whether or not an impairment charge is recorded and the magnitude of such a charge. Due to the acquisition of the ATM Group (see Note 2) the Company recognized goodwill in the amount of $6.2 million in the second quarter of 2012. The goodwill primarily relates to the expected synergies from the merger and has been assigned to the broker-dealer segment of the Company. No impairment charges for goodwill were recognized during the three and six months ended June 30, 2012.
