Properties\n\nOur principal domestic facilities for the HPMC segment include melting operations and production facilities that perform processing and finishing operations, which are all substantially owned. Domestic melting operations are located in Monroe and Bakers, NC, and Richland, WA (vacuum induction melting, vacuum arc re-melt, electro-slag re-melt, plasma melting, electron beam melting). Production of high performance materials, most of which are in long product form, takes place at our domestic facilities in Monroe and Bakers, NC, Richburg, SC, and Oakdale, PA. Our production of highly engineered forgings and machined components takes place at facilities in Cudahy, Appleton and Coon Valley, WI, and Irvine, CA. In addition, we lease a facility in Margate, Florida to perform metal alloy-based additive manufacturing for the aerospace & defense industries.\n\nWithin the AA&S segment, our production of zirconium, hafnium, niobium and related specialty alloys takes place at facilities located in Millersburg, OR and Huntsville, AL. Nickel melting operations are located in Lockport, NY (vacuum induction melting, vacuum arc re-melt, and electro-slag re-melt), and titanium melting operations are located in Albany, OR (vacuum arc re-melt). Our principal AA&S locations for melting flat-rolled specialty materials are located in Brackenridge and Latrobe, PA. Hot-rolling is performed at our domestic facilities in Brackenridge and Washington, PA. Finishing of our flat-rolled products takes place at our domestic facilities located in Vandergrift, WA, Rochester, Monaca, and Zelienople, PA, and Pageland, SC. Substantially all of these properties are owned.\n\nWe lease facilities, primarily sales and administrative offices, in a number of foreign countries, including France, Germany, the U.K., Poland, Mexico, and the People’s Republic of China. We also own highly engineered forging and machining operations in Stalowa Wola, Poland. Through our STAL joint venture, we operate facilities for finishing PRS products in the Xin-Zhuang Industrial Zone, Shanghai, China.\n\n17\n\nOur corporate headquarters in Dallas, TX and enterprise resource center in Pittsburgh, PA are leased.\n\nAlthough our facilities vary in terms of age and condition, we believe that they have been well maintained and are in sufficient condition for us to carry on our activities. See Item 7. “Management’s Discussion and Analysis of Financial Condition and Results of Operations” for further discussion of these impacts."}
