Segment Reporting [Abstract]

Segment Information

The segment information below includes the allocation of expenses shared by one or more operating segments. Although management believes such allocations are reasonable, the operating information does not necessarily reflect how such data might appear if the segments were operated as separate businesses. Inter-segment sales are made at prices comparable to normal, unaffiliated customer sales. The Company does not have any customers who represent 10 percent or more of total revenues.
