The Company tests intangible assets for impairment annually, or more frequently if events or circumstances indicate they could be impaired. Potential impairment indicators include, but are not limited to: a sustained increase in worldwide inventories of oil or gas, sustained reductions in: worldwide oil and gas prices or drilling activity; the profitability or cash flow of oil and gas companies or drilling contractors; available financing or other capital for oil and gas companies or drilling contractors; the market capitalization of the Company or its customers; or, capital investments by drilling companies and oil and gas companies.

During the first quarter of 2020 the coronavirus (COVID-19) outbreak rapidly spread across the world, driving sharp demand destruction for crude oil as whole economies ordered curtailed activity. Members of the Organization of the Petroleum Exporting Countries and other producing countries (OPEC+), including Russia, increased production into the already oversupplied market, decimating oil prices. The result was the Company’s stock price reaching a new low during the quarter and its market capitalization falling below its carrying value. West Texas Intermediate (WTI), a key benchmark for the U.S. oil market, fell more than $40 per barrel from January 1, 2020, to March 31, 2020, (losing two thirds of its value in 90 days) to its lowest level in nearly two decades. As travel restrictions and government directives to shut down businesses increased, demand was expected to continue declining in the second quarter of 2020. Management reduced its forecast accordingly.

In the Company’s view, falling rig count levels in the first quarter and a depressed outlook provided evidence to the equity markets that oil and gas producers were committed to reduced levels of capital investment in drilling, further reducing levels of demand for capital equipment and oilfield services that the Company sells to its customers. Also, due to these prolonged poor market conditions, capital availability to many of the Company’s customers became even more limited and was unlikely to improve near-term. In management’s judgement the facts and circumstances including those described above constituted a triggering event in the first quarter which indicated the Company’s goodwill and other long-lived assets may be impaired. The Company performed a detailed analysis under ASC 350, incorporating this updated outlook, which determined that the fair values were less than the respective carrying values for all of the Company’s business units (“Reporting Units”).

The Company primarily uses the discounted cash flow method to estimate the fair value of its Reporting Units when conducting the impairment test but also considers the comparable companies and representative transaction methods to validate the test result and management’s forecast and other expectations, where possible. The valuation techniques used in the test were consistent with those used during previous testing. Fair value of the Reporting Unit is determined using significant unobservable inputs, or Level 3 in the fair value hierarchy. These inputs are based on internal management estimates, forecasts and judgements, using discounted cash flows. The inputs used in the test were updated to reflect management’s judgement, current market conditions and forecasts.

The discounted cash flow was based on management’s forecast of operating performance for each Reporting Unit. The two main assumptions used, which bear the risk of change and could impact the test result, include the forecast cash flow from operations from each of the Company’s Reporting Units and their respective weighted average cost of capital. The starting point for each of the Reporting Unit’s cash flow from operations was the detailed forecast, modified to incorporate our revised outlook, as appropriate. The Reporting Unit carrying values were adjusted based on the long-lived asset impairment assessment noted below. Cash flows beyond the plan or forecast were estimated using a terminal value calculation which incorporated historical and forecasted financial cyclical trends for each Reporting Unit and considered long-term earnings growth rates. Financial and credit market volatility directly impacts our fair value measurement through the weighted average cost of capital used to determine a discount rate. During times of volatility, significant judgement must be applied to determine whether credit changes are a short-term or long-term trend.

For the first quarter of 2020, the Company recorded $1,295 million in impairment charges to goodwill and $83 million in charges to indefinite-lived intangible assets.

Following the impairment charges, several Reporting Units did not have a fair value substantially in excess of their book value. Further deterioration of market conditions, in management’s judgement, beyond those incorporated into the extended forecast by management, will likely result in additional impairment charges. The remaining goodwill balance for these Reporting Units at September 30, 2020, is as follows: Rig Equipment ($661 million), Marine Construction ($51 million), ReedHycalog ($124 million), M/D Totco ($10 million), Wellsite Services ($174 million), XL Systems ($64 million), Fiberglass Systems ($346 million), and Process and Flow Technologies ($63 million).

At September 30, 2020, the Company has approximately $1,493 million of goodwill, by segment, as follows (in millions):

	Wellbore Technologies			Completion & Production Solutions			Rig Technologies			Total

Impairment of Long-Lived Assets (Excluding Goodwill and Other Indefinite-Lived Intangible Assets)

Long-lived assets, which include property, plant and equipment, right of use, and identified intangible assets, comprise a significant amount of the Company’s total assets. The Company makes judgments and estimates in conjunction with the carrying value of these assets, including amounts to be capitalized, depreciation and amortization methods and estimated useful lives.

The Company identified its Reporting Units as individual asset groups. The carrying values of these asset groups are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amounts may not be recoverable. An impairment loss is recorded in the period in which it is determined that the carrying amount of the asset is not recoverable based on estimated future undiscounted cash flows. We estimate the fair value of these intangible and fixed assets using an income approach that requires the Company to make long-term forecasts of its future revenues and costs related to the assets subject to review. These forecasts require assumptions about demand for the Company’s products and services, future market conditions and technological developments. The forecasts are dependent upon assumptions including those regarding oil and gas prices, the general outlook for the global oil and gas industry, available financing for the Company’s customers, political stability in major oil and gas producing areas, and the potential obsolescence of various types of equipment we sell, among other factors. Financial and credit market volatility directly impacts our fair value measurement through our income forecast. Changes to these assumptions, including, but not limited to: sustained declines in worldwide rig counts below current analysts’ forecasts; collapse of spot and futures prices for oil and gas; significant deterioration of external financing for our customers; higher risk premiums or higher cost of capital; or any other significant adverse economic news could require a provision for impairment.

During the first quarter of 2020, the results of the Company's test for impairment of goodwill and indefinite-lived intangible assets, and the other negative market indicators described above, were a triggering event that indicated that its long-lived tangible assets and finite-lived intangible assets were impaired.

Impairment testing performed in the first quarter resulted in the determination that certain long-lived assets associated with most of the Company’s asset groups were not recoverable. The estimated fair value of these asset groups was below the carrying value and, as a result, during the first quarter of 2020, the Company recorded impairment charges of $209 million to customer relationships, patents, trademarks, tradenames, and other finite-lived intangible assets, $262 million to property, plant and equipment, and $42 million to right-of-use assets. Additionally, the Company recorded a $224 million impairment on its equity investment in unconsolidated affiliates.

The Company has approximately $516 million of identified intangible assets, by segment, as follows (in millions):

	Wellbore Technologies			Completion & Production Solutions			Rig Technologies			Total
Balance at December 31, 2019	$	326		$	275		$	251		$	852
