Segment Reporting [Abstract]

SEGMENT REPORTING

NOTE 16: SEGMENT REPORTING

We have four operating segments organized around our principal product lines: aggregates, concrete, asphalt mix and cement. The vast majority of our activities are domestic. We sell a relatively small amount of products outside the United States. Transactions between our reportable segments are recorded at prices approximating market levels. Management reviews earnings from the product line reporting segments principally at the gross profit level.
