Segment Geographic and Market Information [Abstract]

Segment, Geographic, and Market Information

2)   Segment, Geographic, and Market Information

We determine our operating segments based on the discrete financial information that is regularly evaluated by our chief operating decision maker, our President and Chief Executive Officer, in deciding how to allocate resources and in assessing performance. Intersegment sales are not material and are eliminated in the corporate segment. Our reportable measure of profit or loss for each segment is operating profit, which is defined as net sales less cost of sales and selling, general and administrative expenses related to a segment's operations. The costs deducted to arrive at operating profit do not include several items, such as net interest expense or income taxes.

Our five segments are as follows:

• Minerals and materials - mines, processes and distributes minerals and products for use in various industrial and consumer markets, including metalcasting, pet care, laundry care, and drilling industries;

• Environmental - provides services relating to and processes and distributes clay-based and other products for use as a moisture barrier in commercial construction, landfill liners and in a variety of other industrial and commercial applications;

• Oilfield services - provides a variety of services and equipment rentals for both onshore and offshore applications to customers in the oil and natural gas industry;

• Transportation - includes a long-haul trucking business and a freight brokerage business that provides services domestically to our subsidiaries as well as third-party customers; and

• Corporate - intersegment sales are eliminated in our corporate segment. These are most notably sales between our transportation segment and our minerals and materials and environmental segments as well as sales between our minerals and materials segment to our environmental and oilfield services segments. Corporate segment also includes expenses associated with certain research and development, management, benefits and information technology activities.

Segment assets are those assets used within each segment. Corporate assets include assets used in the operation of this segment as well as those used by or shared amongst our segments, including cash and cash equivalents, certain fixed assets, assets associated with certain employee benefit plans, and other miscellaneous assets.
