Precision Castparts Corp.

Precision Castparts Corp. (PCC) is an American manufacturer of complex metal components and products for aerospace, power and general industrial markets, and a wholly owned subsidiary of Berkshire Hathaway.
PCC is based in Lake Oswego, Oregon, and traces its origins to 1949, when Joseph Cox started a small investment casting operation in Portland, Oregon to make a cutter for his chainsaw products. The casting venture was organised as Precision Castparts Corp. in 1953 and incorporated in Oregon in 1956. Berkshire Hathaway completed its acquisition of PCC on 29 January 2016 for USD 37.2 billion.
PCC describes itself as the market leader in large, complex structural investment castings, airfoil castings, forged components, aerostructures and highly engineered, critical fasteners for aerospace, and the leading producer of airfoil castings for the industrial gas turbine market. Its operations are grouped into Investment Cast Products (PCC Structurals, PCC Airfoils), Forged Products (Wyman-Gordon), Metals Products (TIMET, Special Metals, PCC Energy Group) and Airframe Products (PCC Fasteners, PCC Aerostructures, PCC Engineered Products). The company says a modern aircraft needs an average of 300,000 PCC fasteners, that it casts the world's largest-diameter investment casting at 76 inches, and that PCC Metals developed more than 75% of the nickel alloys used in the oil and gas industry.
As a Berkshire subsidiary PCC no longer files its own annual reports; its last standalone Form 10-K reported approximately 30,100 employees at 29 March 2015 and net sales of USD 10.0 billion in fiscal 2015, of which the aerospace market accounted for 70%. Mark Donegan remains chief executive, the third in the company's history.
