TEI has received 21 skids of liners from Federal Mogul. Our original order was for 19 skids. The additional 2 skids were part overrun pieces and TEI decided to also purchase these for the Industry rather than see them discarded. Sampling of liners from each skid is currently underway. Visual inspection and surface finish analysis of the liners sampled thus far is similar to previous batches. Nine of Seventy-two liners (12%) have been rejected (slightly below 12 micro-inch finish).
