4. Oil and Gas Sales

The Partnership’s oil and condensate production is sold and revenue recognized at or near the Partnership’s wells under short-term purchase contracts at prevailing prices in accordance with arrangements which are customary in the oil industry. Sales of gas applicable to the Partnership’s interest are recorded as revenue when the gas is metered and title transferred pursuant to the gas sales contracts covering the Partnership’s interest in gas reserves. The Partnership uses the sales method to recognize oil and gas revenue whereby revenue is recognized for the amount of production taken regardless of the amount for which the Partnership is entitled based on its working interest ownership.

Substantially all the Partnership’s accounts receivable result from oil and natural gas sales to third parties in the oil and natural gas industry. This concentration of customers may impact the Partnership’s overall credit risk in that these entities may be similarly affected by changes in economic and other conditions. Historically, the Partnership has not experienced significant credit losses on such receivables. No bad debt expense was recorded for the three months ended March 31, 2019 or 2018. The Partnership cannot ensure that such losses will not occur in the future.

The Partnership has only non-operated working interests in oil and gas wells and receives monthly net revenue checks from the operator of these oil and gas wells. It recognizes revenue for oil and condensate when control transfers to the purchaser at a contractually specified delivery point at or near the wellhead at prevailing prices in accordance with arrangements which are customary in the oil and gas industry. Sales of gas applicable to the Partnership’s interest are recorded as revenue when the gas is metered and control is transferred pursuant to the gas sales contracts covering the Partnership’s interest in gas reserves.

The Partnership has reviewed its partnership, joint operating and marketing agreements as they relate to its non-operated working interests and this ASU, which includes provisions regarding revenues and expenses under a gross-versus-net presentation as it relates to principal vs agent relationship, and has evaluated the impact on the presentation of its revenues and expenses under this gross-versus-net presentation guidance. Based on its review of how information about revenue has been presented for other purposes, including disclosures presented outside the financial statements and information used by management for evaluating performance operations, the appropriate categories for the disaggregation of revenue are oil and gas sales, as presented in the Partnership’s financial statements and related disclosures.

Disaggregation of Revenue

The Partnership has identified two material revenue streams in its business: oil sales and natural gas sales. Revenue attributable to each of the Partnership’s identified revenue streams is disaggregated in the Condensed Statements of Operations.

Principal versus agent

In the case of the non-operating agreements, the operator is responsible for providing the goods due to its contractual obligations with the purchaser. Based on the joint operating and marketing agreement arrangements between the Partnership and operator, the Partnership does not take title to the product prior to the operator’s ultimate sale to a customer. The operator is responsible for fulfilling promises to provide specified goods and remitting proceeds back to the Partnership for the Partnership’s proportionate share of the total product sold. MOC, rather than the Partnership, is primarily responsible for fulfilling promises to provide specified goods. MOC, as the operator, enters into the sales contract with the third-party customers and directs all activities from the wellhead to the delivery point that make the commodity available to the customer; there is no agreement between the Partnership and the customers. In the event a production delay occurs because of, for example, well-equipment failure, MOC is responsible for correcting the issues preventing fulfillment of its promises to deliver product to its customers.

Transaction price allocated to remaining performance obligations

For the Partnership’s product sales, the Partnership has utilized the practical expedient in ASC 606 that states that it is not required to disclose the transaction price allocated to remaining performance obligations if the variable consideration is allocated entirely to a wholly unsatisfied performance obligation. Under the operator’s sales contracts, each unit of product represents a separate performance obligation; therefore, future volumes are wholly unsatisfied and disclosure of the transaction price allocated to remaining performance obligations is not required.

Contract balances

Under the Partnership’s joint operating and marketing agreements, the Partnership is entitled to consideration as production occurs at the wellhead and the value of such consideration is an estimate. Final amounts are only determined upon sale by the operator to the ultimate third-party customer, and recorded in “Accounts receivable, affiliate” in its balance sheet.
