Risk Management Activities

Commodity Price Risk. As more fully discussed in Note 12 to the Consolidated Financial Statements included in EOG's 2016 Annual Report, EOG engages in price risk management activities from time to time. These activities are intended to manage EOG's exposure to fluctuations in commodity prices for crude oil and natural gas. EOG utilizes financial commodity derivative instruments, primarily price swap, option, swaption, collar and basis swap contracts, as a means to manage this price risk. EOG has not designated any of its financial commodity derivative contracts as accounting hedges and, accordingly, accounts for financial commodity derivative contracts using the mark-to-market accounting method.

Commodity Derivative Contracts. On March 14, 2017, EOG executed the optional early termination provision granting EOG the right to terminate certain crude oil price swaps with notional volumes of 30,000 barrels per day (Bbld) at a weighted average price of $50.05 per barrel ($/Bbl) for the period March 1, 2017 through June 30, 2017. EOG received cash of $4.6 million for the early termination of these contracts. Presented below is a comprehensive summary of EOG's crude oil price swap contracts for the three months ended March 31, 2017, with notional volumes expressed in Bbld and prices expressed in $/Bbl.

Crude Oil Price Swap Contracts
	Volume (Bbld)	Weighted Average Price ($/Bbl)
2017
January 1, 2017 through February 28, 2017 (closed)	35,000	$	50.04
March 1, 2017 through June 30, 2017 (closed)	30,000	50.05

On March 14, 2017, EOG entered into a crude oil price swap contract for the period March 1, 2017 through June 30, 2017, with notional volumes of 5,000 Bbld at a price of $48.81 per Bbl. This contract offsets the remaining crude oil price swap contract for the same time period with notional volumes of 5,000 Bbld at a price of $50.00 per Bbl. The net cash EOG will receive for settling these contracts is $0.7 million. The offsetting contracts were excluded from the above table.

Presented below is a comprehensive summary of EOG's natural gas price swap contracts for the three months ended March 31, 2017, with notional volumes expressed in million British thermal units (MMBtu) per day (MMBtud) and prices expressed in dollars per MMBtu ($/MMBtu).

Natural Gas Price Swap Contracts
	Volume (MMBtud)	Weighted Average Price ($/MMBtu)
2017
March 1, 2017 through April 30, 2017 (closed)	30,000	$	3.10
May 1, 2017 through November 30, 2017	30,000	3.10
2018
March 1, 2018 through November 30, 2018	35,000	$	3.00

EOG has sold call options which establish a ceiling price for the sale of notional volumes of natural gas as specified in the call option contracts. The call options require that EOG pay the difference between the call option strike price and either the average or last business day NYMEX Henry Hub natural gas price for the contract month (Henry Hub Index Price) in the event the Henry Hub Index Price is above the call option strike price.

In addition, EOG has purchased put options which establish a floor price for the sale of notional volumes of natural gas as specified in the put option contracts. The put options grant EOG the right to receive the difference between the put option strike price and the Henry Hub Index Price in the event the Henry Hub Index Price is below the put option strike price. Presented below is a comprehensive summary of EOG's natural gas call and put option contracts for the three months ended March 31, 2017, with notional volumes expressed in MMBtud and prices expressed in $/MMBtu.

Natural Gas Option Contracts
	Call Options Sold			Put Options Purchased
	Volume (MMBtud)	Weighted Average Price ($/MMBtu)		Volume (MMBtud)	Weighted Average Price ($/MMBtu)
2017
March 1, 2017 through April 30, 2017 (closed)	213,750	$	3.44	171,000	$	2.92
May 1, 2017 through November 30, 2017	213,750	3.44		171,000	2.92
2018
March 1, 2018 through November 30, 2018	120,000	$	3.38	96,000	$	2.94

EOG has also entered into natural gas collar contracts, which establish ceiling and floor prices for the sale of notional volumes of natural gas as specified in the collar contracts. The collars require that EOG pay the difference between the ceiling price and the Henry Hub Index Price in the event the Henry Hub Index Price is above the ceiling price. The collars grant EOG the right to receive the difference between the floor price and the Henry Hub Index Price in the event the Henry Hub Index Price is below the floor price. Presented below is a comprehensive summary of EOG's natural gas collar contracts for the three months ended March 31, 2017, with notional volumes expressed in MMBtud and prices expressed in $/MMbtu.

Natural Gas Collar Contracts
		Weighted Average Price ($/MMbtu)
	Volume (MMBtud)	Ceiling Price		Floor Price
2017
March 1, 2017 through April 30, 2017 (closed)	80,000	$	3.69	$	3.20
May 1, 2017 through November 30, 2017	80,000	3.69		3.20

The following table sets forth the amounts and classification of EOG's outstanding derivative financial instruments at March 31, 2017 and December 31, 2016.  Certain amounts may be presented on a net basis on the Condensed Consolidated Financial Statements when such amounts are with the same counterparty and subject to a master netting arrangement (in millions):

		Fair Value at

Credit Risk. Notional contract amounts are used to express the magnitude of a financial derivative. The amounts potentially subject to credit risk, in the event of nonperformance by the counterparties, are equal to the fair value of such contracts (see Note 11). EOG evaluates its exposure to significant counterparties on an ongoing basis, including those arising from physical and financial transactions. In some instances, EOG renegotiates payment terms and/or requires collateral, parent guarantees or letters of credit to minimize credit risk.

All of EOG's derivative instruments are covered by International Swap Dealers Association Master Agreements (ISDAs) with counterparties. The ISDAs may contain provisions that require EOG, if it is the party in a net liability position, to post collateral when the amount of the net liability exceeds the threshold level specified for EOG's then-current credit ratings. In addition, the ISDAs may also provide that as a result of certain circumstances, including certain events that cause EOG's credit ratings to become materially weaker than its then-current ratings, the counterparty may require all outstanding derivatives under the ISDAs to be settled immediately. See Note 11 for the aggregate fair value of all derivative instruments that were in a net liability position at March 31, 2017 and December 31, 2016. EOG had no collateral posted and held no collateral at March 31, 2017 and December 31, 2016.
