Revenue from Contract with Customer [Abstract]

Revenue from Contract with Customer [Text Block]

REVENUE FROM CONTRACTS WITH CUSTOMERS

We provide gathering, transportation, storage, distribution, marketing and other midstream services primarily to producers, refiners of petroleum products and other market participants located in the Gulf Coast, Midwest and Rocky Mountain regions of the United States of America (the “U.S.”) and Western Canada. In general, we recognize service revenue as the service is performed (“over time”) and product sales revenues are recognized when control of the product transfers to the customer (“point in time”). Our revenue from contracts with customers are disaggregated by segment as follows:

Crude Transportation

• Crude Transportation generates revenue by providing crude oil pipeline and truck transportation services to customers under fee-based contractual arrangements generally based on units of volume transported. In some instances fees are fixed and not dependent on usage, such as take-or-pay arrangements.

Crude Facilities

• Crude Facilities generates revenue by providing crude oil storage and terminalling services primarily to customers at the Cushing Hub under fee-based contractual arrangements that, in some instances are fixed and not dependent on usage. Pump-over and unloading fees are based on per volume fees for units delivered or withdrawn.

Crude Supply and Logistics

• Crude Supply and Logistics performs marketing activities including purchasing crude oil for its own account from producers and aggregators and selling to traders and refiners under contracts generally with initial terms of less than one year. Revenue is recognized based on market prices at the time the commodities are sold. In certain transactions, we purchase inventory from, and sell inventory to, the same counterparty. Such transactions that are entered into in contemplation of one another are recorded on a net basis.

HFOTCO

• HFOTCO generates revenue by providing storage and terminalling services to customers in the Houston Ship Channel. These contractual arrangements typically include fixed take-or-pay fees related to provision of storage and throughput capacity and usage based charges for pump-over, heating, berthing and excess throughput volumes.

• HFOTCO also generates revenue from leases of certain land, tanks and a barge dock, which are accounted for as a direct financing lease and are outside of the scope of ASC 606.

SemGas

• SemGas generates revenue by providing natural gas and natural gas liquids gathering and processing services to customers based on agreements that are a combination of percent of proceeds and fee-based contracts. Initial contract terms can range from monthly and interruptible to the life of the reserves and, upon expiration, continue to renew on a month-to-month or year-to-year evergreen basis. SemGas’ customers include producers, operators, marketers and traders. Gathering and processing fees are generally based on per volume fees. Product sales revenue is generated from the sale of NGLs and residue gas arising from processing at prevailing market prices.

SemCAMS

• SemCAMS generates revenue from its processing plants through volumetric fees for services under contractual arrangements with working interest owners and third-party customers and the pass through of certain operating costs. Pass-through cost recoveries are reported as "Other revenue" in the consolidated statements of operations and comprehensive income (loss). SemCAMS also derives revenue as the owner and operator of pipeline gathering systems that gather gas from multiple wells located in the same production unit and as the owner and operator of pipeline transportation systems that deliver the gathered gas to its processing plant. SemCAMS’ customers include producers of varying sizes. To support operations at our plants, several producers have committed to process all of their current and future natural gas production.

Corporate and Other

• Corporate and Other is not an operating segment, but contains the results of operations for our former Mexican asphalt business and U.K. storage business, which are not significant components of our business.

Key areas of judgment    

Take or pay

Contracts with take-or-pay provisions are recognized over time as the customer simultaneously receives and consumes the benefit of available capacity. Payments made for unused take-or-pay capacity, which allow the customer to carryforward a portion of the unused capacity to future periods, are deferred until it becomes unlikely that the capacity will be used prior to contract expiration. Determining when, or if, the capacity will be used requires judgment.

Percentage of proceeds

Contracts with percentage of proceeds terms typically involve the receipt of natural gas at the wellhead and include gathering, processing and marketing of the resulting NGLs and residue gas with SemGroup retaining a portion of the proceeds from the ultimate sale to a third-party. The terms of these agreements include various gathering and processing fees. The determination of whether the transaction is a purchase at the wellhead by SemGroup with gathering and processing performed on our own account or whether the transaction represents gathering and processing as a service provided to the producer by SemGroup with a purchase and sale of processed gas at the completion of the service, requires judgment and is impacted by when control of the underlying commodity has been deemed to move from the producer to the processor. This determination impacts whether gathering and processing fees are recorded as reductions to cost of sales or recorded as service revenue.

Principal vs. agent

We engage in various types of transactions where we perform marketing activities for producers, such as our percentage of proceeds contracts, or transactions where costs are incurred and reimbursed by customers or other owners in facilities, such as SemCAMS' pass-through costs. These types of transactions require judgment to determine whether we are the principal or an agent in the transaction and as a result whether revenues are recorded gross or net.

Non-cash consideration

SemGroup receives commodities from its customers in the form of plant and field fuel, pipeline loss allowance and retention of drip liquids. The purpose of the receipt of these commodities is to keep the Company whole in the case of minor operational usage or loss of product and is not intended as a consideration for services performed. Therefore, the receipt of these commodities does not represent consideration and is not recorded as revenue. Any net retention of commodities in excess of actual losses is recorded in inventory and recognized as revenue when sold.

Tiered pricing and material rights

We have certain contracts that provide customers with rates that reduce incrementally as volumes increase beyond certain thresholds. These types of agreements require judgment to determine if the option for the customer to acquire additional services constitutes a material right that the customer would not receive without entering into the contract, e.g. the discount exceeds the range of discounts typically given. If it is determined that a material right exists, a portion of the revenue is allocated to that right at contract inception and recognized as revenue as the option for additional services is exercised or when the option expires. In contrast, if it is concluded that the option to acquire additional services reflects standalone selling price, this would constitute a marketing offer and not a material right.

Remaining performance obligations

Most of our service contracts are such that we have the right to consideration from a customer in an amount that corresponds directly with the value to the customer of our performance completed to date. Therefore, we are utilizing the practical expedient in ASC 606-10-55-18 under which we recognize revenue in the amount to which we have the right to invoice. Applying this practical expedient, we are not required to disclose the transaction price allocated to remaining performance obligations under these agreements. However, certain of our agreements, such as "take-or-pay" agreements, do not qualify for the practical expedient. The amount and timing of revenue recognition for such contracts is presented below (in thousands):

	2018		2019		2020		2021		2022		Thereafter
Expected timing of revenue recognized for remaining performance obligations	$	80,242	$	256,782	$	217,510	$	173,283	$	161,903	$	1,387,769

For our product sales contracts, we have elected the practical expedient set out in ASC 606-10-50-14A that states that we are 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 these agreements, each unit of

product represents a separate performance obligation and therefore future volumes are wholly unsatisfied and disclosure of transaction price allocated to remaining performance obligations is not required. Under product sales contracts, the variability arises as both volume and pricing (typically index based) are not known until the product is delivered.

Receivables from contracts with customers

Accounts receivable, net on the condensed consolidated balance sheets represents current receivables from contracts with customers. Certain noncurrent receivables from contracts with customers are included in “other noncurrent assets” on the condensed consolidated balance sheets. These amounts are accruals to recognize revenue for performance to date related to customer deficiencies on minimum volume commitments with make-up rights for which the use of the make-up rights are not probable due to capacity constraints or other factors. Therefore, we have accrued the amount for which no future performance by SemGroup will be required, but for which we do not have a present right to bill the customer until the end of the contract. The balance of noncurrent receivables from customer contracts was (in thousands):

	September 30, 2018		December 31, 2017
Noncurrent receivables	$	10,368	$	—

Noncurrent receivables for the transactions described above were not recorded prior to the adoption of ASC 606 as our policy was to defer recognition of deficiencies with make-up rights until the contractual make-up rights expired.

Deferred revenue

We record deferred revenue when we have received a payment in advance of delivering a product or performing a service. For the three months and nine months ended September 30, 2018, we recognized $0.4 million and $3.6 million, respectively, of revenue which was included in deferred revenue at the beginning of the period.

Costs to obtain or fulfill a contract

Unless material, we expense costs to obtain or fulfill a contract in the period incurred. At September 30, 2018, we had contract assets of $9.5 million related to costs incurred to obtain contracts which had been expensed as incurred under previous guidance. These costs are reported within “other noncurrent assets” on the condensed consolidated balance sheets and are being amortized straight-line over the 25-year life of the related contracts.
