Segment Reporting [Abstract] |
Segment Reporting Disclosure [Text Block] | Note 10. Business Segment Information The Company operates in two segments, POS and TOS. The accounting policies of the Company’s segments are the same as those described in Note 2 of the Company’s annual financial statements for the year ended April 30, 2013, as filed on Form 10-K. The Company evaluates performance of its segments based on profit or loss from operations before stock compensation expense, depreciation and amortization, interest expense, interest income, gain on sale of assets, special charges or benefits, and income taxes. Management uses segment profit information for internal reporting and control purposes and considers it important in making decisions regarding the allocation of capital and other resources, risk assessment, and employee compensation, among other matters. The following tables summarize, for the periods indicated, operating results by business segment (in thousands):
