Derivatives and Risk Management Activities |
Derivatives and Risk Management Activities |
Note 12—Derivatives and Risk Management Activities We identify the risks that underlie our core business activities and use risk management strategies to mitigate those risks when we determine that there is value in doing so. Our policy is to use derivative instruments for risk management purposes and not for the purpose of speculating on commodity price changes. We use various derivative instruments to (i) manage our exposure to commodity price risk as well as to optimize our profits, (ii) manage our exposure to interest rate risk and (iii) manage our exposure to currency exchange rate risk. Our commodity risk management policies and procedures are designed to help ensure that our hedging activities address our risks by monitoring NYMEX, ICE and over-the-counter positions, as well as physical volumes, grades, locations, delivery schedules and storage capacity. Our interest rate and currency exchange rate risk management policies and procedures are designed to monitor our positions and ensure that those positions are consistent with our objectives and approved strategies. Our policy is to formally document all relationships between hedging instruments and hedged items, as well as our risk management objectives and strategies for undertaking the hedge. This process includes specific identification of the hedging instrument and the hedged transaction, the nature of the risk being hedged and how the hedging instrument’s effectiveness will be assessed. Both at the inception of the hedge and on an ongoing basis, we assess whether the derivatives used in a transaction are highly effective in offsetting changes in cash flows or the fair value of hedged items. Commodity Price Risk Hedging Our core business activities contain certain commodity price-related risks that we manage in various ways, including the use of derivative instruments. Our policy is (i) to only purchase product for which we have a market, (ii) to structure our sales contracts so that price fluctuations do not materially affect our operating income and (iii) not to acquire and hold physical inventory or derivatives for the purpose of speculating on commodity price changes. The material commodity-related risks inherent in our business activities can be summarized into the following general categories: Commodity Purchases and Sales — In the normal course of our operations, we purchase and sell commodities. We use derivatives to manage the associated risks and to optimize profits. As of June 30, 2011, net derivative positions related to these activities included: · An approximate 212,900 barrels per day net long position (total of 6.4 million barrels) associated with our crude oil purchases, which was unwound ratably during July 2011 to match monthly average pricing. · A net short spread position averaging approximately 39,300 barrels per day (total of 21.5 million barrels), which hedges a portion of our anticipated crude oil lease gathering purchases through January 2013. These derivatives also hedge the margin associated with anticipated crude oil purchases. These derivatives are time spreads consisting of offsetting purchases and sales between two different months, and other than for changes in the spreads, do not result in exposure to outright price movements. · A net short calender spread call options position averaging approximately 32,200 barrels per day (total of 5.9 million barrels) for the period August 2011 through January 2012. These derivatives also hedge the margin associated with anticipated crude oil purchases. These derivatives are time spreads between two different months, and other than for changes in the spreads, do not result in exposure to outright price movements. · Approximately 5,400 barrels per day on average (total of 2.9 million barrels) of WTS/WTI crude oil basis swaps through December 2012, which hedge anticipated sales of crude oil (WTI). These derivatives are grade spreads between two different grades of crude oil, and other than for changes in the spreads, do not result in exposure to outright price movements. · Approximately 3,100 barrels per day on average (total of 0.9 million barrels) of butane/WTI spread positions, which hedge specific butane sales contracts that are priced as a fixed percentage of WTI and continue through March 2012. These derivatives are cross-commodity spreads between butane and WTI, and other than for changes in the spreads, do not result in exposure to outright price movements. Storage Capacity Utilization — We own approximately 70 million barrels of crude oil, LPG and refined products storage capacity other than that used in our transportation operations. This storage may be leased to third parties or utilized in our own supply and logistics activities, including for the storage of inventory in a contango market. For capacity allocated to our supply and logistics operations, we have utilization risk if the market structure is backwardated. As of June 30, 2011, we used derivatives to manage the risk of not utilizing approximately 3.8 million barrels per month of storage capacity through 2012. These positions are a combination of calendar spread options and futures contracts. These positions involve no outright price exposure, but instead represent potential offsetting purchases and sales between time periods (first month versus second month for example). Inventory Storage — At times, we elect to purchase and store crude oil, LPG and refined products inventory in conjunction with our supply and logistics activities. When we purchase and store inventory, we enter into physical sales contracts or use derivatives to mitigate price risk associated with the inventory. As of June 30, 2011, we had derivatives totaling approximately 9.4 million barrels hedging our inventory. These positions are a combination of swaps and futures contracts. We also purchase waterborne cargos of crude oil and may enter into derivatives to mitigate various price risks associated with the purchase and ultimate sale of crude inventory. As of June 30, 2011, we had approximately 0.5 million barrels of crude oil derivatives hedging the anticipated sale of such crude inventory. Pipeline Loss Allowance Oil — As is common in the pipeline transportation industry, our tariffs incorporate a loss allowance factor that is intended to, among other things, offset losses due to evaporation, measurement and other losses in transit. We utilize derivative instruments to hedge a portion of the anticipated sales of the allowance oil that is to be collected under our tariffs. As of June 30, 2011, our PLA hedges included (i) a net short position consisting of crude oil futures and swaps for an average of approximately 1,700 barrels per day (total of 2.9 million barrels) through December 2015, (ii) a long put option position of approximately 0.4 million barrels through December 2012 and (iii) a long call option position of approximately 0.4 million barrels through December 2012. Natural Gas Purchases and Sales — Our gas storage facilities require minimum levels of natural gas (“base gas”) to operate. For our natural gas storage facilities that are under construction, we anticipate purchasing base gas in future periods as construction is completed. We use derivatives to hedge such anticipated purchases of natural gas. As of June 30, 2011, we have a long futures position of approximately 0.7 Bcf, 3.0 Bcf of long swaps, and a long call option position of approximately 0.7 Bcf related to anticipated base gas purchases. Additionally, our natural gas commercial marketing group captures short-term market opportunities by leasing a portion of our owned or leased storage capacity to engage in related commercial marketing activities. We use various derivatives, including index and basis swaps, to hedge anticipated purchases and sales of natural gas by our commercial marketing group. As of June 30, 2011, we have a short swap position of approximately 6.6 Bcf related to anticipated sales of natural gas, and an approximate 6.3 Bcf long swap position related to anticipated purchases of natural gas. Additionally, we have a net short calendar spread call option position of approximately 3.0 Bcf related to anticipated sales of natural gas. These calls in the aggregate do not result in exposure to outright price movements. All of our commodity derivatives that qualify for hedge accounting are designated as cash flow hedges. We have determined that substantially all of our physical purchase and sale agreements qualify for the NPNS exclusion. Physical commodity contracts that meet the definition of a derivative but are ineligible, or not designated, for the NPNS scope exception are recorded on the balance sheet at fair value, with changes in fair value recognized in earnings. Interest Rate Risk Hedging We use interest rate derivatives to hedge interest rate risk associated with anticipated debt issuances and outstanding debt instruments. The derivative instruments we use to manage this risk consist primarily of interest rate swaps and treasury locks. As of June 30, 2011, AOCI includes deferred gains of $9 million that relate to open and terminated interest rate swaps and treasury locks that were designated for hedge accounting. The terminated interest rate derivatives were cash-settled in connection with the issuance or refinancing of debt agreements. The deferred gain related to these instruments is being amortized to interest expense over the original terms of the hedged debt instruments. During June and July 2011, we entered into six forward starting interest rate swaps to hedge the underlying benchmark interest rate related to forecasted debt issuances through 2013. The following table summarizes the terms of our forward starting interest rate swaps (notional amounts in millions):
Hedged Transaction |  | Number and Types of Derivatives Employed |  | Notional Amount |  | Expected Termination Date |  | Average Rate Locked |  | Accounting Treatment |
Anticipated debt offering |  | 3 forward starting swaps (30-year) |  | $ | 150 |  | 6/17/2013 |  | 4.35 | % | Cash flow hedge |
Anticipated debt offering |  | 3 forward starting swaps (10-year) |  | $ | 150 |  | 6/15/2012 |  | 3.53 | % | Cash flow hedge |
During June 2011, PNG entered into two interest rate swaps to fix the interest rate on a portion of its revolving credit facility. The swaps have an aggregate notional amount of $50 million with an average fixed rate of 1.06% and terminate in June 2014. Concurrent with our January 2011 senior notes issuance, we terminated three forward starting interest rate swaps. See Note 7 for additional disclosure. These swaps had an aggregate notional amount of $100 million and an average fixed rate of 3.6%. We received cash proceeds of $12 million associated with the termination of these swaps. During July 2009, we entered into four interest rate swaps for which we receive fixed interest payments and pay floating-rate interest payments based on three-month LIBOR plus an average spread of 2.42% on a semi-annual basis. The swaps have an aggregate notional amount of $300 million with fixed rates of 4.25%. Two of the swaps terminate in September 2011 and two of the swaps terminate in September 2012. The swaps that terminate in 2012 are designated as fair value hedges. Currency Exchange Rate Risk Hedging Because a significant portion of our Canadian business is conducted in CAD and, at times, a portion of our debt is denominated in CAD, we use foreign currency derivatives to minimize the risks of unfavorable changes in exchange rates. These instruments include foreign currency exchange contracts, forwards and options. As of June 30, 2011, AOCI includes net deferred gains of $11 million that relate to open and settled foreign currency derivatives that were designated for hedge accounting. These foreign currency derivatives hedge the cash flow variability associated with CAD-denominated interest payments on a CAD-denominated intercompany note as a result of changes in the exchange rate. As of June 30, 2011, our outstanding foreign currency derivatives also include derivatives we use to hedge USD-denominated crude oil purchases and sales in Canada. In addition, we may from time to time hedge the commodity price risk associated with a CAD-denominated commodity transaction with a USD-denominated commodity derivative. In conjunction with entering into the commodity derivative, we may enter into a foreign currency derivative to hedge the resulting foreign currency risk. These foreign currency derivatives are generally short-term in nature and are not designated for hedge accounting. The following table summarizes our open forward exchange contracts that exchange CAD for USD on a net basis (in millions):
|  | CAD |  | USD |  | Average Exchange Rate |
2011 (1) |  | $ | 58 |  | $ | 59 |  | CAD $0.97 to US $1.00 |
2012 |  | $ | 15 |  | $ | 15 |  | CAD $1.01 to US $1.00 |
2013 |  | $ | 9 |  | $ | 9 |  | CAD $1.00 to US $1.00 |
(1) Includes $50 million of forward exchange contracts that we entered into during July 2011. Summary of Financial Impact For derivatives that qualify as a cash flow hedge, changes in fair value of the effective portion of the hedges are deferred to AOCI and recognized in earnings in the periods during which the underlying physical transactions impact earnings. For our interest rate swaps that qualify as a fair value hedge, changes in the fair value of the derivative and changes in the fair value of the underlying hedged item, attributable to the hedged risk, are recognized in earnings each period. Derivatives that do not qualify for hedge accounting and the portion of cash flow hedges that are not highly effective in offsetting changes in cash flows of the hedged items are recognized in earnings each period. Cash settlements associated with our derivative activities are reflected as operating cash flows in our consolidated statements of cash flows. A summary of the impact of our derivative activities recognized in earnings for the three and six months ended June 30, 2011 and 2010 is as follows (in millions):

(1) Amounts represent derivative gains and losses that were reclassified from AOCI to earnings during the period to coincide with the earnings impact of the respective hedged transaction. (2) Amounts include gains of approximately $1 million for the three months ended June 30, 2010 and losses of approximately $8 million for the six months ended June 30, 2011 that represent the ineffective portion of our cash flow hedges. These amounts relate to commodity derivatives and are recognized in Supply and Logistics segment revenues during such periods. (3) Interest expense includes a net gain of approximately $1 million for the six months ended June 30, 2011 associated with outstanding interest rate swaps, which are designated as a fair value hedge. (4) Includes realized and unrealized gains or losses for derivatives not designated for hedge accounting during the period.

As of June 30, 2011, there was a net gain of $59 million deferred in AOCI. The total amount of deferred net gain recorded in AOCI is expected to be reclassified to future earnings contemporaneously with (i) the earnings recognition of the underlying hedged commodity transaction, (ii) interest expense accruals associated with underlying debt instruments or (iii) the recognition of a foreign currency gain or loss upon the remeasurement of certain CAD-denominated intercompany balances. Of the total net gain deferred in AOCI at June 30, 2011, we expect to reclassify a net gain of approximately $41 million to earnings in the next twelve months. Of the remaining deferred gain in AOCI, approximately $13 million is expected to be reclassified to earnings prior to 2014 with the remaining deferred gain being reclassified to earnings through 2041. These amounts are predominately based on market prices at the current period end, thus actual amounts to be reclassified will differ and could vary materially as a result of changes in market conditions. During the three and six months ended June 30, 2011, we reclassified a gain of approximately $1 million from AOCI to facilities segment revenues as a result of anticipated hedged transactions that are no longer considered to be probable of occurring. During the three and six months ended June 30, 2010, all of our hedged transactions were probable of occurring. The net deferred gain/(loss), excluding tax effects, recognized in AOCI for derivatives during the three and six months ended June 30, 2011 and 2010 are as follows (in millions):

Our accounting policy is to offset derivative assets and liabilities executed with the same counterparty when a master netting agreement exists. Accordingly, we also offset derivative assets and liabilities with amounts associated with cash margin. Our exchange-traded derivatives are transacted through brokerage accounts and are subject to margin requirements as established by the respective exchange. On a daily basis, our account equity (consisting of the sum of our cash balance and the fair value of our open derivatives) is compared to our initial margin requirement resulting in the payment or return of variation margin. As of June 30, 2011, we had a net broker receivable of approximately $33 million (consisting of initial margin of $65 million reduced by $32 million of variation margin that had been returned to us). As of December 31, 2010, we had a net broker receivable of approximately $99 million (consisting of initial margin of $56 million increased by $43 million of variation margin that had been posted by us). At June 30, 2011 and December 31, 2010, none of our outstanding derivatives contained credit-risk related contingent features that would result in a material adverse impact to us upon any change in our credit ratings. The following table sets forth by level within the fair value hierarchy our financial assets and liabilities that were accounted for at fair value on a recurring basis as of June 30, 2011 and December 31, 2010. Financial assets and liabilities are classified in their entirety based on the lowest level of input that is significant to the fair value measurement. Our assessment of the significance of a particular input to the fair value measurement requires judgment, which affects the placement of assets and liabilities within the fair value hierarchy levels.

(1) Derivative assets and liabilities are presented above on a net basis but do not include related cash margin deposits. The determination of the fair values above includes not only the credit standing of the counterparties involved and the impact of credit enhancements (such as cash deposits and letters of credit) but also the impact of our nonperformance risk on our liabilities. The fair value of our commodity derivatives, interest-rate derivatives and foreign currency derivatives includes adjustments for credit risk. We measure credit risk by deriving a probability of default from market-observed credit default swap spreads as of the measurement date. The probability of default is applied to the net credit exposure of each of our counterparties and includes a recovery rate adjustment. The recovery rate is an estimate of what would ultimately be recovered through a bankruptcy proceeding in the event of default. There were no changes to any of our valuation techniques during the period. Level 1 Included within level 1 of the fair value hierarchy are exchange-traded commodity derivatives such as futures, options and swaps. The fair value of exchange-traded commodity derivatives is based on unadjusted quoted prices in active markets and is therefore classified within level 1 of the fair value hierarchy. Level 2 Included within level 2 of the fair value hierarchy are interest rate derivatives that include interest rate swaps. The fair value of these interest rate derivatives is based on broker or dealer price quotations which are corroborated with market observable inputs including forward interest rates obtained from pricing services. Level 3 Included within level 3 of the fair value hierarchy are over-the-counter commodity derivatives that are traded in markets that are active but not sufficiently active to warrant level 2 classification in our judgment and certain physical commodity contracts. The fair value of our level 3 commodity derivatives is based on broker or dealer price quotations or a valuation model. Our valuation models utilize inputs such as forward prices but do not involve significant management judgments. Rollforward of Level 3 Net Liability The following table provides a reconciliation of changes in fair value of the beginning and ending balances for our derivatives classified as level 3 (in millions):
|  | Three Months Ended |  | Six Months Ended |

Change in unrealized gains/(losses) included in earnings relating to level 3 derivatives still held at the end of the period |  | $ | 13 |  | $ | 10 |  | $ | 11 |  | $ | 9 |
(1) We reported unrealized gains and losses associated with level 3 commodity derivatives in our consolidated statements of operations as Supply and Logistics segment revenues. Gains and losses associated with interest rate derivatives are reported in our consolidated statements of operations as Interest expense. Gains and losses associated with foreign currency derivatives are reported in our consolidated statements of operations as either Supply and Logistics segment revenues, Purchases and related costs, or Other income, net. During the first quarter of 2011, we transferred interest rate and commodity derivatives with an aggregate fair value of $17 million from level 3 to level 2. This transfer resulted from the implementation of additional valuation procedures, using market observable inputs, to validate the broker or dealer price quotations used for fair value measurement. Our policy is to recognize transfers between levels as of the beginning of the reporting period in which the transfer occurred. We believe that a proper analysis of our level 3 gains or losses must incorporate the understanding that these items are generally used to hedge our commodity price risk, interest rate risk and foreign currency exchange risk and will therefore be offset by gains or losses on the underlying transactions.
