(12) Derivative contracts

Derivative contracts have been entered into primarily through our finance and financial products and our utilities and energy businesses. A summary of the liabilities and related notional values of derivative contracts of our finance and financial products businesses follows (in millions).

	December 31, 2016					December 31, 2015
	Liabilities		Notional Value			Liabilities		Notional Value
Equity index put options	$	2,890	$	26,497	(1)	$	3,552	$	27,722	(1)
Credit default (2)		—		—			284		7,792

⁽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⁾  In July 2016, our remaining credit default contract was terminated by mutual agreement with the counterparty. We no longer have any exposure to losses under credit default contracts.

The derivative contract liabilities 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, 2016 follows (in millions).

	2016		2015			2014
Equity index put options	$	662	$	1,008		$	108
Credit default and other		89		(34	)		398
	$	751	$	974		$	506

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

The aggregate intrinsic value (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 $1.0 billion at December 31, 2016 and $1.1 billion at December 31, 2015. 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 four years at December 31, 2016.

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, 2016, 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 $142 million as of December 31, 2016 and $103 million as of December 31, 2015. Derivative contract liabilities are included in accounts payable, accruals and other liabilities and were $145 million as of December 31, 2016 and $237 million as of December 31, 2015. 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.
