Discontinued Operation

On March 15, 2016, the Company completed the sale of TPI for $55,070 in cash, subject to customary working capital adjustments. Under the terms of the sale, $1,500 of the purchase price was placed into escrow pending adjustment based upon the final calculation of the working capital at closing. The Company and the buyer agreed to the final working capital adjustment during the third quarter of 2016, which resulted in the full escrowed amount being returned to the buyer. The sale resulted in pre-tax and after-tax gains of $2,003 and $1,306, respectively, for the year ended December 31, 2016.

Prior to the sale of TPI, the Company had two reportable segments consisting of its Plastics segment and its Metals segment. Subsequent to the sale of TPI, which represented the Company's Plastics segment in its entirety, the Company has only one reportable segment.
