Segment Reporting [Abstract]

SEGMENT REPORTING

NOTE 15: SEGMENT REPORTING

We have four operating segments organized around our principal product lines: aggregates, concrete, asphalt mix and cement.

The Aggregates segment produces and sells aggregates (crushed stone, sand and gravel, sand, and other aggregates) and related products and services (transportation and other). During 2011, the Aggregates segment principally served markets in nineteen states, the District of Columbia, the Bahamas and Mexico with a full line of aggregates, and eight additional states with railroad ballast. Customers use aggregates primarily in the construction and maintenance of highways, streets and other public works and in the construction of housing and commercial, industrial and other nonresidential facilities. Customers are served by truck, rail and water distribution networks from our production facilities and sales yards. Due to the high weight-to-value ratio of aggregates, markets generally are local in nature. Quarries located on waterways and rail lines allow us to serve remote markets where local aggregates reserves may not be available. We sell a relatively small amount of construction aggregates outside the United States. Nondomestic net sales were $16,678,000 in 2011, $23,380,000 in 2010 and $20,118,000 in 2009.

The Concrete segment produces and sells ready-mixed concrete in six states and the District of Columbia. Additionally, we produce and sell, in a limited number of these markets, other concrete products such as block and precast and resell purchased building materials related to the use of ready-mixed concrete and concrete block.

The Asphalt Mix segment produces and sells asphalt mix in three states primarily in our southwestern and western markets.

Aggregates comprise approximately 78% of ready-mixed concrete by weight and 95% of asphalt mix by weight. Our Concrete and Asphalt Mix segments are almost wholly supplied with their aggregates requirements from our Aggregates segment. These intersegment sales are made at local market prices for the particular grade and quality of product utilized in the production of ready-mixed concrete and asphalt mix. Customers for our Concrete and Asphalt Mix segments are generally served locally at our production facilities or by truck. Because ready-mixed concrete and asphalt mix harden rapidly, delivery is time constrained and generally confined to a radius of approximately 20 to 25 miles from the producing facility.

The Cement segment produces and sells Portland and masonry cement in both bulk and bags from our Florida cement plant. Other Cement segment facilities in Florida import and export cement, clinker and slag and either resell, grind, blend, bag or reprocess those materials. This segment also includes a Florida facility that mines, produces and sells calcium products. Our Concrete segment is the largest single customer of our Cement segment.

The vast majority of our activities are domestic. Long-lived assets outside the United States, which consist primarily of property, plant & equipment, were $142,988,000 in 2011, $150,157,000 in 2010 and $163,479,000 in 2009. Transactions between our reportable segments are recorded at prices approximating market levels.
