Derivative contracts

Note 12.    Derivative contracts

Derivative contracts are used primarily by our finance and financial products businesses and our railroad, utilities and energy businesses. As of June 30, 2011 and December 31, 2010, substantially all of the derivative contracts of our finance and financial products businesses are not designated as hedges for financial reporting purposes. These contracts were initially entered into with the expectation that the premiums received would exceed the amounts ultimately paid to counterparties. Changes in the fair values of such contracts are reported in earnings as derivative gains/losses. A summary of derivative contracts of our finance and financial products businesses follows (in millions).

(1)	Represents the aggregate undiscounted amount payable at the contract expiration dates assuming that the value of each index is zero at the contract expiration date.
(2)	Represents the maximum undiscounted future value of losses payable under the contracts. The number of losses required to exhaust contract limits under substantially all of the contracts is dependent on the loss recovery rate related to the specific obligor at the time of a default.
(3)	Included in Other assets of finance and financial products businesses.

The equity index put option contracts are European style options written on four major equity indexes. Future payments, if any, under these contracts will be required if the underlying index value is below the strike price at the contract expiration dates which occur between June 2018 and January 2026. We received the premiums on these contracts in full at the contract inception dates and therefore we have no counterparty credit risk. We entered into no new contracts in 2010 or 2011.

At June 30, 2011, the aggregate intrinsic value (the undiscounted liability assuming the contracts are settled on their future expiration dates based on the June 30, 2011 index values and foreign currency exchange rates) was approximately $3.9 billion. However, these contracts may not be unilaterally terminated or fully settled before the expiration dates and therefore the ultimate amount of cash basis gains or losses on these contracts may not be determined for many years. The remaining weighted average life of all contracts was approximately 9.5 years at June 30, 2011.

Our credit default contracts pertain to various indexes of non-investment grade (or “high yield”) corporate issuers, as well as investment grade state/municipal and individual corporate debt issuers. These contracts cover the loss in value of specified debt obligations of the issuers arising from default events, which are usually from their failure to make payments or bankruptcy. Loss amounts are subject to aggregate contract limits. We entered into no new contracts in 2010 or 2011.

The high yield index contracts are comprised of specified North American corporate issuers (usually 100 in number at inception) whose obligations are rated below investment grade. High yield contracts remaining in-force at June 30, 2011 expire in 2012 and 2013. State and municipality contracts are comprised of over 500 state and municipality issuers and had a weighted average contract life at June 30, 2011 of approximately 9.7 years. Potential obligations related to approximately 50% of the notional value of the state and municipality contracts cannot be settled before the maturity dates of the underlying obligations, which range from 2019 to 2054.

Premiums on the high yield index and state/municipality contracts were received in full at the inception dates of the contracts and, as a result, we have no counterparty credit risk. Our payment obligations under certain of these contracts are on a first loss basis. Losses under other contracts are subject to aggregate deductibles that must be satisfied before we have any payment obligations.

Individual corporate credit default contracts primarily relate to issuers of investment grade obligations. In most instances, premiums are due from counterparties on a quarterly basis over the terms of the contracts. As of June 30, 2011, all of the remaining contracts in-force will expire in 2013.

With limited exceptions, our equity index put option and credit default contracts contain no collateral posting requirements with respect to changes in either the fair value or intrinsic value of the contracts and/or a downgrade of Berkshire’s credit ratings. As of June 30, 2011, our collateral posting requirement under contracts with collateral provisions was $25 million compared to $31 million at December 31, 2010. As of June 30, 2011, had Berkshire’s credit ratings (currently AA+ from Standard & Poor’s and Aa2 from Moody’s) been downgraded below either A- by Standard & Poor’s or A3 by Moody’s an additional $1.1 billion would have been required to be posted as collateral.

Our railroad and regulated utility subsidiaries are exposed to variations in the market prices in the purchases and sales of natural gas and electricity and in the purchases of fuel. Derivative instruments, including forward purchases and sales, futures, swaps and options, are used to manage these price risks. Unrealized gains and losses under the contracts of our regulated utilities that are probable of recovery through rates are recorded as a regulatory net asset or liability. Unrealized gains or losses on contracts accounted for as cash flow or fair value hedges are recorded in accumulated other comprehensive income or in net earnings, as appropriate. Derivative contract assets included in other assets of railroad, utilities and energy businesses were $142 million and $231 million as of June 30, 2011 and December 31, 2010, respectively. Derivative contract liabilities included in accounts payable, accruals and other liabilities of railroad, utilities and energy businesses were $464 million as of June 30, 2011 and $621 million as of December 31, 2010.
