Segment Reporting Disclosure [Text Block] | Note 11. Segment Information Segment information is prepared on the same basis that our chief operating decision maker ("CODM"), our CEO, uses to manage our segments, evaluate financial results, and make key operating decisions. Our four reportable segments are organized primarily by the nature of the goods and services they sell. Our CODM uses segment revenues, organic revenues growth (non-GAAP), and gross profit to allocate resources and to assess segment performance. Monthly, the CODM reviews forecast-to-actual and prior-to-current period variances in segment revenue and in segment gross profit to inform decisions regarding capital and personnel deployment. Our CODM also reviews non-GAAP adjusted operating income, defined as operating income excluding non-cash items such as depreciation, amortization and stock-based compensation, to further manage operations. The following tables set forth our segment information:
