6.	Revenue Recognition

The Company’s products and services are sold based upon purchase orders or contracts with customers that include fixed or determinable prices and do not generally include right of return or other significant post-delivery obligations. The majority of our revenue streams record revenue at a point in time when a performance obligation has been satisfied by transferring control of promised goods or services to the customer. Revenue is recognized net of any taxes collected from customers, which are subsequently remitted to governmental authorities.

Payment terms and conditions vary by contract type. In instances where the timing of revenue recognition differs from the timing of invoicing on contracts with a duration of one year or longer, we have determined our contracts generally do not include a significant financing component, as they are structured to include progress billings commensurate with revenue recognized over time. We have elected to apply the practical expedient that does not require an adjustment for a significant financing component if, at contract inception, the period between when we transfer the promised goods or service to the customer and when the customer pays for the goods or service is one year or less.

The Company elects to treat shipping and handling costs as costs to fulfill a performance obligation instead of as a separate performance obligation. We recognize the cost for shipping and handling when incurred, generally when control over the products has transferred to the customer, as an expense in cost of sales.

Our contracts with customers often include promises to transfer multiple products and services to a customer. Determining whether products and services are considered distinct performance obligations that should be accounted for separately versus together may require significant judgment. We take into consideration the degree of integration of the related products and services, the level of customization of the product for the customer, and the interdependency of the products and services.

Judgment is also required to determine the stand-alone selling price (“SSP”) for each distinct performance obligation. To determine the SSP, the Company uses the price at which the products and services would be sold separately to the customer. We also review past sales transactions to confirm invoice prices for each distinct performance obligation reasonably approximate SSP and that there are no significant deviations. A discount, when provided, is also allocated based on the relative SSP of the various products and services.

We may provide other credits or incentives, which are accounted for as variable consideration when determining the transaction price. These credits or incentives are estimated at contract inception and updated at the end of each reporting period as additional information becomes available and recognized only to the extent that it is probable that a significant reversal of any incremental revenue will not occur.

For revenue that is not recognized at a point in time, the Company follows accounting guidance for revenue recognized over time, as follows:

Revenue Recognition under Long-term Construction Contracts

The Company uses the over-time method to account for certain long-term construction contracts in the Completion & Production Solutions and Rig Technologies segments. These long-term construction contracts include the following characteristics:

•

the contracts include custom designs for customer specific applications;

•

the structural design is unique and requires significant engineering efforts; and

•

the Company has an enforceable right to payment for performance completed to date including a reasonable profit.

Because of control transferring over time, revenue is recognized based on the extent of progress towards completion of the performance obligation. We generally use the cost-to-cost (input) measure of progress for our contracts because it best depicts the transfer of assets to the customer which occurs as we incur costs on our contracts. Under the cost-to-cost measure of progress, the extent of progress towards completion is measured based on the ratio of costs incurred to date to the total estimated costs at completion of the performance obligation. Revenues, including estimated fees or profits, are recorded proportionally as costs are incurred. Costs to fulfill include labor, materials and subcontractors’ costs, and other direct costs. If estimates of total costs to be incurred on a performance obligation exceed total estimates of revenue to be earned, a provision for the entire loss on the performance obligation is recognized in the period the loss is determined.

For most of our contracts, the customer contracts with us to provide a significant service of integrating a complex set of tasks and components into a single project or capability. Hence, the entire contract is accounted for as one performance obligation.

Due to the nature of the work required to be performed on many of our performance obligations, the estimation of total revenue and cost at completion is complex, subject to many variables and requires significant judgment. It is common for our long-term contracts to contain late delivery fees, work performance guarantees, and other provisions that can either increase or decrease the transaction price. We estimate variable consideration at the most likely amount to which we expect to pay or be entitled to. We include variable consideration in the estimated transaction price to the extent it is probable that a significant reversal of cumulative revenue recognized will not occur or when the uncertainty associated with the variable consideration is resolved. Our estimates of variable consideration and determination of whether to include estimated amounts in the transaction price are based largely on an assessment of our anticipated performance and all information (historical, current and forecasted) that is reasonably available to us. Net revenue recognized from our performance obligations satisfied in previous periods was $22 million for the three months ended March 31, 2018 primarily due to change orders.

Service and Repair Work

For those contracts in which we are providing a service to the customer, the output method is utilized to measure progress due to the manner in which the customer receives and derives value from the services being provided. For repair contracts, we generally use the cost-to-cost measure of progress for our contracts because it best depicts the transfer of assets to the customer which occurs as we incur costs on our contracts.

Remaining Performance Obligations

Remaining performance obligations represents the transaction price of firm orders for all revenue streams for which work has not been performed on contracts with an original expected duration of one year or more. The optional disclosures for the remaining performance obligations of royalty contracts, service contracts for which there is a right to invoice, and short-term contracts that are expected to have a duration of one year or less have not been disclosed.

As of March 31, 2018, the aggregate amount of the transaction price allocated to remaining performance obligations was $2,523 million. The Company expects to recognize approximately $895 million in revenue for the remaining performance obligations in 2018 and $1,628 million in 2019 and thereafter.

Costs to Obtain and Fulfill a Contract

We recognize an asset for the incremental costs of obtaining a contract, such as sales commissions, with a customer when we expect the benefit of those costs to be longer than one year. Costs to fulfill a contract, such as set-up and mobilization costs, are also capitalized when we expect to recover those costs. These contract costs are deferred and amortized over the period of contract performance. Total capitalized costs to obtain and fulfill a contract and the related amortization were immaterial during the periods presented and are included in other current and long-term assets on our consolidated balance sheets.

We apply the practical expedient to expense costs as incurred for costs to obtain a contract with a customer when the amortization period would have been one year or less.

Disaggregation of Revenue

The following tables disaggregate our revenue by destinations, as we believe it best depicts how the nature, amount, timing and uncertainty of our revenue and cash flows are affected by economic factors. In the tables below, North America includes only the U.S. and Canada. (in millions):

Contract Assets and Liabilities

Contract assets include unbilled amounts typically resulting from sales under long-term contracts when the cost-to-cost method of revenue recognition is utilized and revenue recognized exceeds the amount billed to the customer, and right to payment is not only subject to the passage of time. There were no impairment losses recorded on contract assets for the periods ending March 31, 2018 or 2017.

Contract liabilities consist of advance payments and billings in excess of revenue recognized and deferred revenue. For the balance at December 31, 2017, we reclassified $240 million of advance payments and deferred revenue from accrued liabilities to contract liabilities to conform with the 2018 presentation.

The changes in the carrying amount of contract assets and contract liabilities are as follows (in millions):
