Commitments and Contingencies Disclosure [Abstract]
Contingencies and Commitments	Note 19. Contingencies and Commitments We are parties in a variety of legal actions that routinely arise out of the normal course of business, including legal actions seeking to establish liability directly through insurance contracts or indirectly through reinsurance contracts issued by Berkshire subsidiaries. Plaintiffs occasionally seek punitive or exemplary damages. We do not currently believe that such normal and routine litigation will have a material effect on our financial condition or results of operations. Berkshire and certain of its subsidiaries are also involved in other kinds of legal actions, some of which assert or may assert claims or seek to impose fines and penalties. We currently believe that any liability that may arise as a result of other pending legal actions will not have a material effect on our consolidated financial condition or results of operations. On August 8, 2015, Berkshire entered into a definitive agreement with Precision Castparts Corp. (“PCC”) to acquire for $235 per share of common stock in cash, all outstanding PCC shares of common stock, other than the shares we already own (about 2.7 million shares or 1.96%), for aggregate consideration of approximately $31.7 billion. A special meeting of PCC shareholders for the purpose of voting on whether or not to approve the agreement has been scheduled for November 19, 2015. The transaction requires approval by a majority of PCC’s outstanding shares. In addition to the approval of PCC shareholders, the closing of the acquisition is subject to clearance under the Hart-Scott-Rodino (“HSR”) Act and competition clearance in certain foreign jurisdictions. Clearance under the HSR Act was obtained on October 5, 2015. It is expected that the remaining competition clearances will be obtained and that the acquisition will be completed no later than the end of the first quarter of 2016. PCC is a worldwide, diversified manufacturer of complex metal components and products. It serves the aerospace, power, and general industrial markets. PCC is a market leader in manufacturing complex structural investment castings and forged components for aerospace markets, machined airframe components, and highly engineered, critical fasteners for aerospace applications, and in manufacturing airfoil castings for the aerospace and industrial gas turbine markets. PCC also is a leading producer of titanium and nickel superalloy melted and mill products for the aerospace, chemical processing, oil and gas, and pollution control industries, and manufactures extruded seamless pipe, fittings, and forgings for power generation and oil and gas applications. On November 13, 2014, Berkshire entered into a definitive agreement with The Procter & Gamble Company (“P&G”) whereby it will acquire the Duracell business from P&G. Duracell is a leading manufacturer of high-performance alkaline batteries and is an innovator in renewable power and wireless charging technologies. Pursuant to the agreement, in exchange for a recapitalized Duracell Company, which will include approximately $1.7 billion in cash at closing, P&G will receive shares of P&G common stock currently held by Berkshire subsidiaries which had a fair value at September 30, 2015 of approximately $3.8 billion. The transaction is currently expected to close in the first quarter of 2016. We own a 50% interest in a joint venture, Berkadia Commercial Mortgage LLC (“Berkadia”), with Leucadia National Corporation (“Leucadia”) owning the other 50% interest. Berkadia is a servicer of commercial real estate loans in the U.S., performing primary, master and special servicing functions for U.S. government agency programs, commercial mortgage-backed securities transactions, banks, insurance companies and other financial institutions. A significant source of funding for Berkadia’s operations is through the issuance of commercial paper. Repayment of the commercial paper is supported by a $2.5 billion surety policy issued by a Berkshire insurance subsidiary. Leucadia has agreed to indemnify us for one-half of any losses incurred under the policy. On September 30, 2015, the aggregate amount of Berkadia commercial paper outstanding was $2.47 billion.
