A standard natural gas capacity agreement provides the customer with temporary use of a portion of a natural gas pipeline. Gas capacity agreements may be short- or long-term and may encompass various pricing mechanisms, including fixed capacity fees as well as usage charges.
Issues associated with accounting for natural gas capacity agreements include determining the appropriate accounting model to apply to the agreement in its entirety, as well as related issues associated with unaccounted for gas and natural gas imbalances.

5.5.1 Accounting for natural gas capacity agreements

A natural gas capacity agreement should be evaluated using the commodity contract assessment framework (see UP 1). After identifying the contract deliverables, the parties should first determine whether the capacity agreement contains a lease. If the contract does not contain a lease, the reporting entity should next assess whether it is a derivative in its entirety. If not, a reporting entity should consider whether the contract contains any embedded derivatives requiring separation from the host contract. If neither lease nor derivative accounting apply, the parties would account for the natural gas capacity agreement as an executory contract (i.e., on an accrual basis). The accounting model applied impacts initial and subsequent recognition and measurement, as discussed in the following sections.

5.5.1.1 Lease accounting

ASC 842 provides guidance for determining whether an arrangement is or contains a lease.

Excerpt from ASC 842-10-15-3

A contract is or contains a lease if the contract conveys the right to control the use of identified property, plant, or equipment (an identified asset) for a period of time in exchange for consideration. A period of time may be described in terms of the amount of use of an identified asset (for example, the number of production units that an item of equipment will be used to produce).

Accordingly, an agreement should be accounted for as a lease only if it conveys the right to use an identified asset, which must be physically distinct and may be an entire asset or a portion of an asset, as discussed in ASC 842-10-15-16.

Excerpt from ASC 842-10-15-16

A capacity portion of an asset is an identified asset if it is physically distinct (for example, a floor of a building or a segment of a pipeline that connects a single customer to the larger pipeline). A capacity or other portion of an asset that is not physically distinct (for example, a capacity portion of a fiber optic cable) is not an identified asset, unless it represents substantially all of the capacity of the asset and thereby provides the customer with the right to obtain substantially all of the economic benefits from use of the asset.

Once a reporting entity concludes that an arrangement involves an identified asset, it must evaluate whether the agreement conveys the right to control that asset. In accordance with the guidance in ASC 842-10-15-4, an arrangement conveys control of an asset if the customer has both of the following:
  • The right to obtain substantially all of the economic benefits from use of the identified asset
  • The right to direct the use of the identified asset

Natural gas capacity agreements typically specify the natural gas pipeline. An agreement that conveys substantially all of the capacity of a pipeline will likely contain a lease. In contrast, if an agreement conveys only a portion of the capacity of the gas pipeline (which is typically the case), it will generally not contain a lease because it would not contain an identified asset. For example, a natural gas capacity agreement that provides the shipper with all of the pipeline capacity on a certain path for a period of time may be a lease (if the criteria in ASC 842-10-15-4 are met), whereas an agreement for only 25% of the capacity likely is not, as the capacity is not considered physically distinct in the context of the overall capacity of the pipeline.
See UP 2 for further information on determining whether an arrangement is or contains a lease.
If the contract does not contain a lease, the parties should then consider whether the contract is a derivative in its entirety or includes an embedded derivative.

5.5.1.2 Derivative accounting

A natural gas capacity contract provides the purchaser with use of a portion of a natural gas pipeline. Derivative accounting typically does not apply to this type of contract because the criterion of net settlement is not met. However, the parties should evaluate whether this type of contract is a derivative in its entirety in accordance with the criteria in ASC 815-10-15-83. Figure UP 5-8 summarizes key considerations in assessing whether a typical arrangement for the purchase or sale of natural gas capacity is a derivative in its entirety.

Notional amount and underlying
Met
  • Notional (amount of capacity) and underlying (price for the capacity) are typically specified.
No initial net investment
Met
  • No initial net investment is typically required.
Net settlement
Generally not met
  • Contractual net settlement is typically not permitted in a natural gas capacity agreement.
  • Generally, there is no market mechanism for net settlement and no active market for spot sales of natural gas capacity; however, markets should be monitored to determine if a market mechanism or active market develops.
In general, we would not expect a contract for natural gas capacity to be accounted for as a derivative because it fails the net settlement criterion.

ASC 815-10-15-83(c)

Net settlement. The contract can be settled net by any of the following means:
  1. Its terms implicitly or explicitly require or permit net settlement.
  2. It can readily be settled net by a means outside the contract.
  3. It provides for delivery of an asset that puts the recipient in a position not substantially different from net settlement.

Factors to consider in assessing whether a natural gas capacity contract has the characteristic of net settlement are discussed in the following paragraphs. See UP 3.2.3 for further information on overall application of the net settlement criterion.
Net settlement under contract terms
When evaluating whether the net settlement criterion is met, a reporting entity should first consider whether the contract terms explicitly or implicitly provide for net settlement of the entire contract. Natural gas capacity agreements typically require the capacity owner to provide natural gas capacity (i.e., physical delivery is required). Further, although pricing of a natural gas capacity agreement may be based on locational price differences, the agreement itself does not typically permit net settlement. However, the type of contract and its terms should be reviewed for any implicit net settlement terms or liquidating damage provisions, which may imply the contract could be net settled.
Net settlement through a market mechanism
In this form of net settlement, one of the parties is required to deliver an asset, but there is an established market mechanism that facilitates net settlement outside the contract. ASC 815-10-15-110 through 15-116 provide guidance on indicators to consider in assessing whether an established market mechanism exists. A key aspect of a market mechanism is that one of the parties to the agreement can be fully relieved of its rights and obligations under the contract.
Because it is the capacity agreement being assessed, the evaluation is based on whether there are buyers standing ready to relieve the reporting entity of all of its rights and obligations for the natural gas capacity contract itself. The Federal Energy Regulatory Commission (FERC) provides market pricing for short-term capacity agreements (less than one year). Therefore, short- and long-term natural gas capacity agreements have different characteristics and may have different markets. We understand that there may be some bilateral activity in certain locations within North America, with trading of capacity among market participants to manage excess capacity and meet obligations on a short-term basis for near term delivery, but often not for the full term of a contract. In addition, pipeline companies maintain electronic bulletin boards that provide some information; however, these postings include all transactions, including pre-arranged deals that may be tariff-based. The FERC guidelines regulating transactions on these bulletin boards should be considered in assessing whether net settlement under a market mechanism exists. Although we understand that there is some activity in the market, it does not appear that there is sufficient liquidity to support the conclusion that a market mechanism exists for natural gas capacity for most contracts. The key factor in this evaluation is whether there are quoted market prices and buyers standing ready to transact for the entire contract (i.e., for the full volume and term of the contract).
Net settlement by delivery of an asset that is readily convertible to cash
Whether there is an active spot market for the particular asset being sold under the contract is the key factor in assessing whether an asset is readily convertible to cash. Current market conditions should always be considered in this analysis. To be deemed an active spot market, a market must have transactions with sufficient frequency and volume to provide pricing information on an ongoing basis. In addition, quoted prices from that market must be readily available on an ongoing basis. See UP 3.2.3.3 for further information on the determination of whether a market is active.
Because it is the capacity agreement being assessed, the evaluation is based on whether the natural gas capacity itself is readily convertible to cash. The fact that the capacity facilitates the movement of natural gas, which is readily convertible to cash, has no bearing on this evaluation. Although we understand that there is some trading of natural gas capacity, based on the current structure of the markets, we are not aware of any active spot markets for capacity in the United States.
Overall conclusion
We are not aware of a market mechanism or active spot market for natural gas capacity contracts in the US and thus we believe that derivative accounting is generally not applicable to these contracts. However, a reporting entity should evaluate all facts and circumstances in concluding on the appropriate accounting for a specific natural gas capacity contract. In addition, a reporting entity should monitor its conclusion each reporting period because markets may evolve, potentially rendering this type of contract a derivative. Reporting entities also should evaluate the contract to determine if there are any embedded derivatives that require separation from the host contract (assuming the contract does not meet the definition of a derivative in its entirety). See UP 3.4 for information on evaluating embedded derivatives.
Reporting entities may also consider conditionally designating natural gas capacity contracts under the normal purchases and normal sales scope exception if physical delivery is probable throughout the life of the contract and the other criteria for application of this exception are met (ASC 815-10-15-22 through 15-51 as applicable). If a conditionally designated normal purchases and normal sales contract meets the definition of a derivative at a later date, it would be accounted for as a normal purchases and normal sales contract from the time the contract becomes a derivative. Absent such a designation, the reporting entity would be required to initially fair value the contract when it meets the definition of a derivative.
See UP 3.3.1 for further information on the normal purchases and normal sales scope exception.
Question UP 5-5
Should a reporting entity account for a natural gas capacity contract as a derivative (i.e., a basis swap)?
PwC response
Generally, no. A natural gas capacity contract allows the buyer to capture a spread between two locations. A reporting entity can use a natural gas capacity contract to move natural gas through the pipelines and capture a pricing spread between two locations. However, the reporting entity must trade the natural gas capacity contract together with natural gas inventory or market purchases to capture the basis differences. Absent a capacity market, the natural gas capacity contract itself does not settle based on natural gas locational price differences. Thus, such contracts are not derivatives unless they meet the net settlement criterion as discussed above.

5.5.2 Accounting for unaccounted for gas

Unaccounted for gas represents the difference between the amount of gas the shipper supplies to the pipeline system, compared to the amount it withdraws. The main causes for unaccounted for gas include leakage (also referred to as “line loss”), measurement of gas at other than base conditions, different measurement timing for the injection and withdrawal meters, as well as other factors. The magnitude of unaccounted for gas can vary based on the length and number of metering points in a network.
In general, we expect losses from unaccounted for gas to be included as an expense in the same line item as other gas expenses. Reporting entities should also consider the impact unaccounted for gas may have on the recognition of unbilled revenue, inventory balances, and the level of certain fuel-related regulatory assets.
