Summary of Significant Accounting Policies

The accompanying unaudited consolidated condensed financial statements of Nabors have been prepared in conformity with the generally accepted accounting principles in the United States (“GAAP”). Pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”), certain information and footnote disclosures normally included in annual financial statements prepared in accordance with GAAP have been omitted. Therefore, these financial statements should be read together with our annual report on Form 10-K for the year ended December 31, 2015, as amended (“2015 Annual Report”). In management’s opinion, the unaudited condensed consolidated financial statements contain all adjustments necessary to state fairly our financial position as of September 30, 2016 and the results of operations, comprehensive income (loss), cash flows and changes in equity for the periods presented herein. Interim results for the nine months ended September 30, 2016 may not be indicative of results that will be realized for the full year ending December 31, 2016.

Principles of Consolidation

Our condensed consolidated financial statements include the accounts of Nabors, as well as all majority owned and non-majority owned subsidiaries required to be consolidated under GAAP. All significant intercompany accounts and transactions are eliminated in consolidation.

Investments in operating entities where we have the ability to exert significant influence, but where we do not control operating and financial policies, are accounted for using the equity method. Our share of the net income (loss) of these entities is recorded as earnings (losses) from unconsolidated affiliates in our condensed consolidated statements of income (loss). The investments in these entities are included in investment in unconsolidated affiliates in our condensed consolidated balance sheets. We have historically recorded our share of the net income (loss) of our equity method investment in CJES on a one-quarter lag, as we are not able to obtain the financial information of CJES on a timely basis. During the third quarter of 2016, CJES filed for bankruptcy, at which time we ceased accounting for our investment in CJES as an equity method investment and now report this investment at our estimate of fair value. See Note 3 — Investments in Unconsolidated Affiliates.

Revenue Recognition

We recognize revenues and costs on daywork contracts daily as the work progresses. For certain contracts, we receive lump-sum payments for the mobilization of rigs and other drilling equipment. We defer revenue related to mobilization periods and recognize the revenue over the term of the related drilling contract. At September 30, 2016 and December 31, 2015, our deferred revenues classified as other long-term liabilities were $342.5 million and $324.3 million, respectively. At September 30, 2016 and December 31, 2015, our deferred revenues classified as accrued liabilities were $269.6 million and $340.5 million, respectively.

Costs incurred related to a mobilization period for which a contract is secured are deferred and recognized over the term of the related drilling contract. Costs incurred to relocate rigs and other drilling equipment to areas in which a contract has not been secured are expensed as incurred. We defer recognition of revenue on amounts received from customers for prepayment of services until those services are provided. At September 30, 2016 and December 31, 2015, our deferred expenses classified as other current assets were $57.5 million and $79.6 million, respectively. At September 30, 2016 and December 31, 2015, our deferred expenses classified as other long-term assets were $77.7 million and $68.9 million, respectively.

We recognize revenue for top drives and instrumentation systems we manufacture when the earnings process is complete. This generally occurs when products have been shipped, title and risk of loss have been transferred, collectability is probable, and pricing is fixed and determinable.

We recognize, as operating revenue, proceeds from business interruption insurance claims in the period that the applicable proof of loss documentation is received. Proceeds from casualty insurance settlements in excess of the carrying value of damaged assets are recognized in other expense (income), net in the period that the applicable proof of loss documentation is received. Proceeds from casualty insurance settlements that are expected to be less than the carrying value of damaged assets are recognized at the time the loss is incurred and recorded in other expense (income), net.

We recognize reimbursements received for out-of-pocket expenses incurred as revenues and account for out-of-pocket expenses as direct costs.

Inventory

Inventory is stated at the lower of cost or net realizable value. Cost is determined using the first-in, first-out or weighted-average cost methods and includes the cost of materials, labor and manufacturing overhead. Inventory included the following:


	September 30,		December 31,
	2016		2015
	(In thousands)
Raw materials	$	98,072	$	105,217
Work-in-progress		26,057		29,710
Finished goods		17,805		18,897
	$	141,934	$	153,824

Property, Plant and Equipment

We review our assets for impairment when events or changes in circumstances indicate that their carrying amounts may not be recoverable. If the estimated undiscounted future cash flows are not sufficient to support the asset’s recorded value, an impairment charge is recognized to reduce the carrying amount of the long-lived asset to its estimated fair value. The determination of future cash flows requires the estimation of dayrates and utilization, and such estimates can change based on market conditions, technological advances in the industry or changes in regulations governing the industry.

For an asset classified as held for sale, we consider the asset impaired when its carrying amount exceeds fair value less its cost to sell. Fair value is determined in the same manner as an impaired long-lived asset that is held and used.

Significant and unanticipated changes to the assumptions could result in future impairments. A continuation of the lower oil and natural gas prices experienced over the last two years could continue to adversely affect the demand for and prices of our services. As such, we will continue to assess our asset fleet, particularly our legacy and undersized rigs. Should we continue experiencing weakening in the market for a prolonged period for any specific rig class, this could result in future impairment charges or retirements of assets. As the determination of whether impairment charges should be recorded on our long-lived assets is subject to significant management judgment, and an impairment of these assets could result in a material charge on our condensed consolidated statements of income (loss), management believes that accounting estimates related to impairment of long-lived assets are critical.

Goodwill

We review goodwill for impairment annually during the second quarter of each fiscal year or more frequently if events or changes in circumstances indicate that the carrying amount of such goodwill and intangible assets exceed their fair value. We initially assess goodwill for impairment based on qualitative factors to determine whether to perform the two-step annual goodwill impairment test, a Level 3 fair value measurement. After our qualitative assessment, step one of the impairment test compares the estimated fair value of the reporting unit to its carrying amount. If the carrying amount exceeds the fair value, a second step is required to measure the goodwill impairment loss. The second step compares the implied fair value of the reporting unit’s goodwill to its carrying amount. If the carrying amount exceeds the implied fair value, an impairment loss is recognized in an amount equal to the excess.

Our estimated fair values of our reporting units incorporate judgment and the use of estimates by management. Potential factors requiring assessment include a further or sustained decline in our stock price, declines in oil and natural gas prices, a variance in results of operations from forecasts, a change in operating strategy of assets and additional transactions in the oil and gas industry. Another factor in determining whether impairment has occurred is the relationship between our market capitalization and our book value. As part of our annual review, we compare the sum of our reporting units’ estimated fair value, which includes the estimated fair value of non-operating assets and liabilities, less debt, to our market capitalization and assess the reasonableness of our estimated fair value. Any of the above-mentioned factors may cause us to re-evaluate goodwill during any quarter throughout the year.

Based on our annual review during the second quarter of 2016, we did not record a goodwill impairment. No events were noted in the current quarter that would cause us to revise our previous assessment. However, a continuation of the lower natural gas or oil prices experienced over the last two years could continue to adversely affect demand for and prices of our services. This could result in future impairment charges, particularly in our U.S. Drilling and Rig Services segments.

- Definition

Disclosure of accounting policy for major classes of inventories, bases of stating inventories (for example, lower of cost or market), methods by which amounts are added and removed from inventory classes (for example, FIFO, LIFO, or average cost), loss recognition on impairment of inventories, and situations in which inventories are stated above cost. If inventory is carried at cost, this disclosure includes the nature of the cost elements included in inventory.

- Definition

Disclosure of accounting policy for revenue recognition. If the entity has different policies for different types of revenue transactions, the policy for each material type of transaction is generally disclosed. If a sales transaction has multiple element arrangements (for example, delivery of multiple products, services or the rights to use assets) the disclosure may indicate the accounting policy for each unit of accounting as well as how units of accounting are determined and valued. The disclosure may encompass important judgment as to appropriateness of principles related to recognition of revenue. The disclosure also may indicate the entity's treatment of any unearned or deferred revenue that arises from the transaction.
