Derivative contracts

(12) Derivative contracts

Derivative contracts have been entered into primarily through our finance and financial products and our energy businesses. Derivative contract liabilities associated with our finance and financial products businesses are concentrated in equity index put option and credit default contracts. A summary of those liabilities and related notional values follows (in millions).

	December 31, 2015					December 31, 2014
	Liabilities		Notional Value			Liabilities		Notional Value
Equity index put options	$	3,552	$	27,722	(1)	$	4,560	$	29,469	(1)
Credit default		284		7,792	(2)		250		7,792	(2)
	$	3,836				$	4,810

⁽¹⁾  Represents the aggregate undiscounted amounts payable assuming that the value of each index is zero at each contract’s expiration date. Certain of these contracts are denominated in foreign currencies. Notional amounts are based on the foreign currency exchange rates as of each balance sheet date.

⁽²⁾  Represents the maximum undiscounted future value of losses payable under the contracts, if all underlying issuers default and the residual value of the specified obligations is zero.

The derivative contracts of our finance and financial products businesses are recorded at fair value and the changes in the fair values of such contracts are reported in earnings as derivative gains/losses. We entered into these contracts with the expectation that the premiums received would exceed the amounts ultimately paid to counterparties. A summary of the derivative gains/losses included in our Consolidated Statements of Earnings in each of the three years ending December 31, 2015 follows (in millions).

	2015			2014		2013
Equity index put options	$	1,008		$	108	$	2,843
Credit default		(34	)		397		(213	)
Other, principally interest rate and foreign currency		—			1		(22	)
	$	974		$	506	$	2,608

The equity index put option contracts were written between 2004 and 2008. These contracts are European style options written on four major equity indexes and will expire between June 2018 and January 2026. Future payments, if any, under any given contract will be required if the underlying index value is below the strike price at the contract expiration date. We received the premiums on these contracts in full at the contract inception dates and therefore have no counterparty credit risk.

The aggregate intrinsic value (which is the undiscounted liability assuming the contracts are settled based on the index values and foreign currency exchange rates as of the balance sheet date) of our equity index put option contracts was approximately $1.1 billion at December 31, 2015 and $1.4 billion at December 31, 2014. However, these contracts may not be unilaterally terminated or fully settled before the expiration dates. Therefore, the ultimate amount of cash basis gains or losses on these contracts will not be determined for several years. The remaining weighted average life of all contracts was approximately five years at December 31, 2015.

Our remaining credit default contract was written in 2008 and relates to approximately 500 zero-coupon municipal debt issues with maturities ranging from 2019 to 2054. The underlying debt issues have a weighted average maturity of approximately 15.75 years. Pursuant to the contract terms, future loss payments would be required in the event of non-payment by the issuer and non-performance by the primary financial guarantee insurers under their contracts. Payments under our contract, if any, are not required prior to the maturity dates of the underlying obligations. Our premium under this contract was received at the inception of this contract and therefore we have no counterparty credit risk.

A limited number of our equity index put option contracts contain collateral posting requirements with respect to changes in the fair value or intrinsic value of the contracts and/or a downgrade of Berkshire’s credit ratings. As of December 31, 2015, we did not have any collateral posting requirements. 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, collateral of up to $1.1 billion could be required to be posted.

Our regulated utility subsidiaries are exposed to variations in the prices of fuel required to generate electricity, wholesale electricity purchased and sold and natural gas supplied for customers. Derivative instruments, including forward purchases and sales, futures, swaps and options, are used to manage a portion of these price risks. Derivative contract assets are included in other assets and were $103 million as of December 31, 2015 and $108 million as of December 31, 2014. Derivative contract liabilities are included in accounts payable, accruals and other liabilities and were $237 million as of December 31, 2015 and $230 million as of December 31, 2014. Net derivative contract assets or liabilities of our regulated utilities that are probable of recovery through rates, are offset by regulatory liabilities or assets. Unrealized gains or losses on contracts accounted for as cash flow or fair value hedges are recorded in other comprehensive income or in net earnings, as appropriate.
