19. Revenue from Contracts with Customers
Cokemaking
Substantially all our coke sales are made pursuant to long-term, take-or-pay agreements with Cliffs Steel and U.S. Steel, who are two of the largest blast furnace steelmakers in North America. The take-or-pay provisions of our agreements require our customers to purchase all or substantially all of the coke volumes produced as specified in the agreements or pay the contract price for any tonnage they do not purchase. The take-or-pay provisions of our agreements also require us to deliver minimum annual tonnage, which vary by contract, and have historically been approximately 4.1 million tons, covering at least 90 percent of each facility's nameplate capacity. The take-or-pay provisions also require our customers to purchase such volumes of coke or pay the contract price for any tonnage they elect not to take.
As a result of the impacts the COVID-19 global pandemic has had on our customers, in July 2020, SunCoke entered into customer agreement amendments, providing near-term coke supply relief for our customers, in exchange for extending certain agreements. Subsequent to these amendments, in October 2020, the contract expiration date of the Haverhill II contract with Cliffs Steel was further extended from June 2023 to June 2025. Our coke sales agreements have approximately 17.6 million tons of unsatisfied or partially unsatisfied performance obligations, which are expected to be delivered over an average remaining contract term of approximately six years.
Our coke sales prices include an operating cost component, a coal cost component and a return of capital component. Operating costs under two of our coke sales agreements are contractual, subject to an annual adjustment based on an inflation index. Under our other four coke sales agreements operating costs are passed through to the respective customers subject to an annually negotiated budget, in some cases subject to a cap annually adjusted for inflation, and generally we share any difference in costs from the budgeted amounts with our customers. Our coke sales agreements contain pass-through provisions for coal and coal procurement costs, subject to meeting contractual coal-to-coke yields. To the extent that the actual coal-to-coke yields are less than the contractual standard, we are responsible for the cost of the excess coal used in the cokemaking process. Conversely, to the extent our actual coal-to-coke yields are higher than the contractual standard, we realize gains. The reimbursement of pass-through operating and coal costs from these coke sales agreements are considered to be variable consideration components included in the cokemaking sales price. The return of capital component for each ton of coke sold to the customer is determined at the time the coke sales agreement is signed and is effective for the term of each sales agreement. This component of our coke sales prices is intended to provide an adequate return on invested capital and may differ based on investment levels and other considerations. The actual return on invested capital at any facility is also impacted by favorable or unfavorable performance on pass-through cost items. Revenues are recognized when performance obligations to our customers are satisfied in an amount that reflects the consideration that we expect to receive in exchange for the coke.
Logistics
In our logistics business, handling and/or mixing services are provided to steel, coke (including some of our domestic cokemaking facilities), electric utility, coal producing and other manufacturing based customers. Materials are transported in numerous ways, including rail, truck, barge or ship. We do not take possession of materials handled, but rather act as intermediaries between our customers and end users, deriving our revenues from services provided on a per ton basis. The handling and mixing services consist primarily of two performance obligations, unloading and loading of materials.
Revenues are recognized when the customer receives the benefits of the services provided, in an amount that reflects the consideration that we will receive in exchange for those services.
Estimated take-or-pay revenue of approximately $35 million from all of our multi-year logistics contracts is expected to be recognized over the next three years for unsatisfied or partially unsatisfied performance obligations as of December 31, 2020.
Energy
Our energy sales are made pursuant to either steam or energy supply and purchase agreements or is sold into the regional power market. Our cokemaking ovens utilize efficient, modern heat recovery technology designed to combust the coal’s volatile components liberated during the cokemaking process and use the resulting heat to create steam or electricity for sale. The energy provided under these arrangements results in transfer of control over time. Revenues are recognized over time as energy is delivered to our customers, in an amount based on the terms of each arrangement.
Operating and Licensing Fees
Operating and licensing fees are made pursuant to long-term contracts with ArcelorMittal Brazil, where we operate a Brazilian cokemaking facility. The licensing fees are based upon the level of production required by our customer as well as a fixed annual fee. Operating fees include the full pass-through of the operating costs of the Brazilian facility as well as a per ton fee based on the level of production required by our customer. Revenues are recognized over time as our customers receive and consume the benefits in an amount that corresponds directly with the value provided to the customer to date.
