Segment Information
 
FASB ASC 280, Segment Reporting, establishes standards for public companies relating to the reporting of financial and descriptive information about their operating segments in financial statements.  Operating segments are components of an enterprise about which separate financial information is available that is evaluated regularly by chief operating decision makers in the allocation of resources and the assessment of performance.  Our management identifies segments based upon major revenue sources as shown in the tables below.  However, management does not track assets by segment.
