Segment Information [Abstract]

Segment Information

12) Segment Information

We determined our reportable segments under the provisions of U.S. GAAP related to disclosures about segments of an enterprise. Our three reportable segments are based on differences in product lines and are as follows:

Metal Bearing Components Segment

• Erwin Plant

• Mountain City Plant

• Pinerolo Plant

• Veenendaal Plant

• Kysucke Plant

• Kunshan Plant

Plastic and Rubber Components Segment

• Danielson Plant

• Lubbock Plant

Precision Metal Components Segment

• Wellington Plant 1

• Wellington Plant 2

Note: The segment information below includes the following former facilities. The Eltmann Plant was deconsolidated from NN on January 20, 2011. The Tempe plant ceased operations August 31, 2010.

All of the facilities in the Metal Bearing Components Segment are engaged in the production of precision steel balls, steel rollers, and metal retainers and automotive specialty products used primarily in the bearing industry. The Plastic and Rubber Components Segment facilities are engaged in the production of plastic retainers for bearing components, automotive components, electronic instrument cases and other molded components used in a variety of industrial and consumer applications and precision rubber bearing seals for the bearing, automotive, industrial, agricultural, and aerospace markets. The Precision Metal Components Segment is engaged in the production of highly engineered precision metal components and subassemblies including, highly engineered shafts, mechanical components, complex precision assembled and tested parts and fluid system components for the automotive, HVAC, fluid power, and diesel engine industries.

The accounting policies of the segments are the same as those described in the summary of significant accounting policies. We evaluate segment performance based on segment net income (loss) after income tax expense (benefit). We account for inter-segment sales and transfers at current market prices. We did not have any individually material inter-segment transactions during 2012, 2011, or 2010.
