Segment Reporting Disclosure [Text Block]

21.   SEGMENT INFORMATION

In September 2008, the Board approved a plan to transfer Network Security business to O2Security along with its Series A preference shares financing.  In anticipation of the business transfer, management identified two reportable segments, including Integrated Circuit Group and Network Security Group. The Integrated Circuit Group’s core products and principal source of revenue are its power management semiconductors.  These semiconductor products are produced with digital, analog, and mixed signal integrated circuit (“IC”) manufacturing processes.  The Network Security Group’s system security solution products include support for VPN and firewalls, which provide security functions between computer systems and networks, including the transmission of data across the Internet.  In November 2010, the Company determined to discontinue the Network Security Group.  Please see discussions in note 3.

The Company does not identify or allocate assets by operating segment, nor does the CODM evaluate operating segments using discrete asset information.  The Company does not have inter-segment revenue, and, accordingly, there is none to be reported.  The Company does not allocate gains and losses from interest and other income, or income taxes to operating segments.  The accounting policies for segment reporting are the same as for the Company as a whole.

Operating segment net sales and operating income (loss), including the discontinued Network Security Group, were as follows:
