Notes to Consolidated Financial Statements (Continued)
(11) Derivative contracts (Continued)
Derivative gains/losses of our finance and financial products businesses included in our Consolidated Statements of
Earnings for each of the three years ending December 31, 2011 were as follows (in millions).
2011 2010 2009
Equity index put options ............................................................. $(1,787) $ 172 $2,713
Credit default obligations ............................................................ (251) 250 789
Other ............................................................................ (66) (161) 122
$(2,104) $ 261 $3,624
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 have no counterparty credit risk. We entered into no new contracts in 2010 or 2011.
At December 31, 2011, the aggregate intrinsic value (the undiscounted liability assuming the contracts are settled on their
future expiration dates based on the December 31, 2011 index values and foreign currency exchange rates) was approximately
$6.2 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 will not be determined for many years. The
remaining weighted average life of all contracts was approximately 9 years at December 31, 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 December 31, 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 December 31, 2011 of approximately 9.3 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 December 31, 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 December 31, 2011, our collateral posting requirement under contracts with collateral provisions was
$238 million compared to $31 million at December 31, 2010. If Berkshire’s credit ratings (currently AA+ from Standard &
Poor’s and Aa2 from Moody’s) are downgraded below either A- by Standard & Poor’s or A3 by Moody’s, additional collateral
of up to $1.1 billion could be required to be posted.
Our regulated utility subsidiaries and our railroad 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
