Notes to Financial Statements

Basis of Presentation and Significant Accounting Policies [Text Block]

Note 1 — Summary of Significant Accounting Policies

Organization and Principles of Consolidation.

Newpark Resources, Inc. was organized in 1932 as a Nevada corporation. In 1991, we changed our state of incorporation to Delaware. The consolidated financial statements include our company and our wholly-owned subsidiaries (“we”, “our” or “us”). All intercompany transactions are eliminated in consolidation.

We are a geographically diversified oil and gas industry supplier providing products and services primarily to the oil and gas exploration (“E&P”) industry. We operate our business through two reportable segments: Fluids Systems and Mats and Integrated Services. Our Fluids Systems segment provides customized drilling fluids solutions to E&P customers globally, operating through four geographic regions: North America, Europe, the Middle East and Africa (“EMEA”), Latin America, and Asia Pacific. Our Mats and Integrated Services segment provides composite mat rentals, well site construction and related site services to oil and gas customers at well, production, transportation and refinery locations in the U.S. In addition, mat rental activity is expanding into applications in other industries, including petrochemicals, utilities, and pipeline. We also sell composite mats to E&P customers outside of the U.S., and to domestic customers outside of the oil and gas industry.

Use of Estimates and Market Risks

The preparation of financial statements in conformity with accounting principles generally accepted in the United States (“US GAAP”) requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Estimates used in preparing our consolidated financial statements include, but are not limited to the following: allowances for product returns, allowances for doubtful accounts, reserves for self-insured retentions under insurance programs, estimated performance and values associated with employee incentive programs, fair values used for goodwill impairment testing, undiscounted future cash flows used for impairment testing of long-lived assets and valuation allowances for deferred tax assets.

Our operating results depend primarily on oil and gas drilling activity levels in the markets we serve. Drilling activity, in turn, depends on oil and gas commodity pricing, inventory levels, product demand and regulatory restrictions. Oil and gas prices and activity are cyclical and volatile. This market volatility has a significant impact on our operating results.

Cash Equivalents.

All highly liquid investments with a remaining maturity of three months or less at the date of acquisition are classified as cash equivalents.

Restricted

Cash.

Cash that is restricted as to withdrawal or usage is recognized as restricted cash.

Allowance for Doubtful Accounts.

Reserves for uncollectible accounts receivable are determined on a specific identification basis when we believe that the required payment of specific amounts owed to us is not probable. The majority of our revenues are from mid-sized and international oil companies as well as government-owned or government-controlled oil companies, and we have receivables in several foreign jurisdictions. Changes in the financial condition of our customers or political changes in foreign jurisdictions could cause our customers to be unable to repay these receivables, resulting in additional allowances.

Allowance for Product Returns.

We maintain reserves for estimated customer returns of unused products in our Fluids Systems segment. The reserves are established based upon historical customer return levels and estimated gross profit levels attributable to product sales.

Inventories.

Inventories are stated at the lower of cost (principally average cost) or market. Certain conversion costs associated with the acquisition, production, blending and storage of inventory in our Fluids Systems segment as well as in the manufacturing operations in the Mats and Integrated Services segment are capitalized as a component of the carrying value of the inventory and expensed as a component of cost of revenues as the products are sold. Reserves for inventory obsolescence are determined based on the fair value of the inventory using factors such as our historical usage of inventory on-hand, future expectations related to our customers’ needs, market conditions and the development of new products.

Property, Plant and Equipment.

Property, plant and equipment are recorded at cost. Additions and improvements that extend the useful life of the assets are capitalized. Maintenance and repairs are charged to expense as incurred. The cost of property, plant and equipment sold or otherwise disposed of and the accumulated depreciation thereon are eliminated from the property and related accumulated depreciation accounts, and any gain or loss is credited or charged to income.

For financial reporting purposes, depreciation is provided on property, plant and equipment, including assets held under capital leases, primarily utilizing the straight-line method over the following estimated useful service lives or lease term:

Computer hardware and office equipment	3	-	5	years
Computer software	3	-	10	years
Autos & light trucks	5	-	7	years
Furniture, fixtures & trailers	7	-	10	years
Composite mats (rental fleet)	7	-	12	years
Machinery and heavy equipment	5	-	15	years
Owned buildings	20	-	39	years
Leasehold improvements	Lease term, including reasonably assured renewal periods

Goodwill and Other Intangible Assets

. Goodwill represents the excess of the purchase price of acquisitions over the fair value of the net identifiable assets acquired. Goodwill and other intangible assets with indefinite lives are not amortized. Intangible assets with finite useful lives are amortized either on a straight-line basis over the asset’s estimated useful life or on a basis that reflects the pattern in which the economic benefits of the asset are realized. Any period costs of maintaining intangible assets are expensed as incurred.

Impairment of Long-Lived Assets

. Goodwill and other indefinite-lived intangible assets are tested for impairment annually as of November 1, or more frequently, if an indication of impairment exists. The impairment test includes a comparison of the carrying value of net assets of our reporting units, including goodwill, with their estimated fair values, which we determine using a combination of a market multiple and discounted cash flow approach. If the carrying value exceeds the estimated fair value, an impairment charge is recorded in the period in which such review is performed. We identify our reporting units based on our analysis of several factors, including our operating segment structure, evaluation of the economic characteristics of our geographic regions within each of our operating segments, and the extent to which our business units share assets and other resources.

We review property, plant and equipment, finite-lived intangible assets and certain other assets for impairment whenever events or changes in circumstances indicate that the carrying amount may not be recoverable. We assess recoverability based on expected undiscounted future net cash flows. In estimating expected cash flows, we use a probability-weighted approach. Should the review indicate that the carrying value is not fully recoverable; the amount of impairment loss is determined by comparing the carrying value to the estimated fair value.

Insurance

. We maintain reserves for estimated future payments associated with our self-insured employee healthcare programs, as well as the self-insured retention exposures under our general liability, auto liability and workers compensation insurance policies. Our reserves are determined based on historical experience under these programs, including estimated development of known claims and estimated incurred-but-not-reported claims.

Treasury Stock

Treasury stock is carried at cost, which includes the entire cost of the acquired stock.

Revenue Recognition

. The Fluids Systems segment recognizes sack and bulk material additive revenues upon shipment of materials and passage of title. Formulated liquid systems revenues are recognized when utilized or lost downhole while drilling. An allowance for product returns is maintained, reflecting estimated future customer product returns. Engineering and related services are provided to customers as an integral component of the fluid system delivery, at agreed upon hourly or daily rates, and revenues are recognized when the services are performed.

For the Mats and Integrated Services segment, revenues from the sale of mats are recognized when title passes to the customer, which is upon shipment or delivery, depending upon the terms of the underlying sales contract. Revenues for services and rentals provided by this segment are generated from both fixed-price and unit-priced contracts, which are short-term in duration. The activities under these contracts include site preparation, pit design, construction, drilling waste management, and the installation and rental of mat systems for a period of time generally not to exceed 60 days. Revenues from services provided under these contracts are recognized as the specified services are completed. Revenues from any subsequent extensions to the rental agreements are recognized over the extension period.

Shipping and handling costs are reflected in cost of revenues, and all reimbursements by customers of shipping and handling costs are included in revenues.

Income Taxes

. We provide for deferred taxes using an asset and liability approach by measuring deferred tax assets and liabilities due to temporary differences existing at year end using currently enacted tax rates and laws that will be in effect when the differences are expected to reverse. We reduce deferred tax assets by a valuation allowance when, based on our estimates, it is more likely than not that a portion of those assets will not be realized in a future period. The estimates utilized in recognition of deferred tax assets are subject to revision, either up or down, in future periods based on new facts or circumstances. We evaluate uncertain tax positions and record a liability as circumstances warrant.

Stock-Based Compensation

. All share-based payments to employees, including grants of employee stock options, are recognized in the income statement based on their fair values. We use the Black-Scholes option-pricing model for measuring the fair value of stock options granted and recognize stock-based compensation based on the grant date fair value, net of an estimated forfeiture rate, for all share-based awards, on a straight-line basis over the vesting term. Performance-based restricted stock units are valued at the date of grant using the Monte Carlo valuation model.

Foreign Currency

Translation

. The functional currency for substantially all international subsidiaries is their respective local currency. Financial statements for these international subsidiaries are translated into U.S. dollars using the exchange rate at each balance sheet date for assets and liabilities and the average exchange rates in effect during the respective period for revenues and expenses. Exchange rate adjustments resulting from translation of foreign currency financial statements are reflected in accumulated other comprehensive loss in stockholders’ equity whereas exchange rate adjustments resulting from foreign currency denominated transactions are recorded in income. At December 31, 2015 and 2014, accumulated other comprehensive loss related to foreign subsidiaries reflected in stockholders’ equity amounted to $58.3 million and $32.0 million, respectively.

Derivative Financial Instruments

. We monitor our exposure to various business risks including interest rates and foreign currency exchange rates and occasionally use derivative financial instruments to manage the impact of certain of these risks. At the inception of a new derivative, we designate the derivative as a cash flow or fair value hedge or we determine the derivative to be undesignated as a hedging instrument based on the underlying facts. We do not enter into derivative instruments for trading purposes.

Reclassifications.

Certain prior year amounts have been reclassified to conform to the current year presentation.

New Accounting Standards

In April 2014, the Financial Accounting Standards Board (“FASB”) issued updated guidance that changes the criteria for reporting discontinued operations including enhanced disclosure requirements. Under the new guidance, only disposals representing a strategic shift in operations should be presented as discontinued operations. Those strategic shifts should have a major effect on the organization´s operations and financial results. The new guidance was effective for us in the first quarter of 2015; however, the adoption did not have a material effect on our consolidated financial statements.

In April and August 2015, the FASB issued updated guidance that changes the presentation of debt issuance costs in financial statements. Under the new guidance, an entity is required to present debt issuance costs in the balance sheet as a direct deduction from the related debt liability rather than as an asset, except for debt issuance costs related to revolving debt agreements, which may continue to be presented as an asset. Amortization of the costs will continue to be reported as interest expense. The new guidance would have been effective for us in the first quarter of 2016, however, as permitted, we elected to early adopt the new guidance retrospectively in 2015. As such, we have reclassified the presentation of debt issuance costs as a direct deduction from the related debt liability, except for debt issuance costs related to our revolving debt agreements, in each of the accompanying balance sheets and related disclosures.

In November 2015, the FASB issued updated guidance to simplify the balance sheet classification of deferred taxes. Under the new guidance, an entity is required to present deferred tax assets and liabilities as noncurrent in the balance sheet based on an analysis of each taxpaying component within a jurisdiction. The new guidance would have been effective for us in the first quarter of 2017, however, as permitted, we elected to early adopt the new guidance retrospectively in 2015. As such, we have reclassified the presentation of deferred tax assets and liabilities as noncurrent in each of the accompanying balance sheets and related disclosures.

In May 2014, the FASB amended the existing accounting standards for revenue recognition. The amendments are based on the principle that revenue should be recognized to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. In July 2015, the FASB deferred the effective date of the new guidance by one year and provided entities the option to early adopt the new guidance. The new guidance is effective for us in the first quarter of 2018 with early adoption permitted in the first quarter of 2017. The amendments may be applied retrospectively to each prior period presented or retrospectively with the cumulative effect recognized as of the date of initial application. We are currently evaluating the impact of these amendments, including the adoption and transition alternatives on our consolidated financial statements.

In July 2015, the FASB issued updated guidance that simplifies the subsequent measurement of inventory. It replaces the current lower of cost or market test with the lower of cost or net realizable value test. Net realizable value is defined as the estimated selling prices in the ordinary course of business, less reasonably predictable costs of completion, disposal, and transportation. The new guidance is effective prospectively for us in the first quarter of 2017 with early adoption permitted. We are currently evaluating the impact of the new guidance on our consolidated financial statements.

In September 2015, the FASB issued updated guidance that eliminates the requirement to restate prior periods to reflect adjustments made to provisional amounts recognized in a business combination. The new guidance requires that an acquirer recognize adjustments to provisional amounts that are identified during the measurement period in the reporting period in which the adjustment amounts are determined. The new guidance is effective prospectively for us in the first quarter of 2016.

Notes to Financial Statements

Disposal Groups, Including Discontinued Operations, Disclosure [Text Block]

Note 2 — Discontinued Operations

In 2013, we initiated a process to sell our Environmental Services business, and in March of 2014 we completed the sale of the business for $100 million in cash, subject to adjustment based on actual working capital conveyed at closing. Cash proceeds from the sale were $89.8 million in 2014, net of transaction related expenses, including the adjustment related to final working capital conveyed at closing. The agreement significantly limits our post-closing environmental obligations, including those related to the waste transfer and disposal facilities. In addition, $8 million of the sales price was withheld in escrow associated with transaction representations, warranties and indemnities, with $4 million scheduled to be released at each of the nine-month and 18-month anniversary of the closing. In December 2014, the buyer made certain claims for indemnification under the terms of the agreement, which defers the release of the escrow funds until such claims are resolved. Further discussion of the buyer’s claims and related litigation is contained in Note 14. As a result of the sale transaction, we recorded a gain on the disposal of the business of $34.0 million ($22.1 million after-tax) in the first quarter of 2014. The results of operations for this business have been classified as discontinued operations for all periods presented.

Summarized results of operations from discontinued operations are as follows:

(In thousands)	2014		2013

Revenues	$	11,744	$	65,002

Income from discontinued operations before income taxes		1,770		17,773
Income from discontinued operations, net of tax		1,152		12,701
Gain from disposal of discontinued operations before income taxes		33,974		-
Gain from disposal of discontinued operations, net of tax		22,117		-

- Definition

The entire disclosure related to a disposal group. Includes, but is not limited to, a discontinued operation, disposal classified as held-for-sale or disposed of by means other than sale or disposal of an individually significant component.

Note 3 — Inventories

Inventories consisted of the following items at December 31:

(In thousands)		2015		2014


Raw materials:
Drilling fluids	$	133,934	$	152,076
Mats		657		1,531
Total raw materials		134,591		153,607

Blended drilling fluids components		25,343		40,971

Finished goods- mats		3,723		1,978

Total inventories	$	163,657	$	196,556

Raw materials consist primarily of barite, chemicals, and other additives that are consumed in the production of our drilling fluid systems. Our blended drilling fluids components consist of base drilling fluid systems that have been either mixed internally at our mixing plants or purchased from third party vendors. These base systems require raw materials to be added, as required to meet specified customer requirements.

In the fourth quarter of 2015, we recognized a $2.2 million charge reported in cost of revenues to reduce the carrying value of diesel-based drilling fluid inventory in the Fluids Systems segment. The charge resulted from lower of cost or market adjustments due to the decline in selling prices for our diesel-based drilling fluid products coupled with declines in replacement costs of diesel fuel.

Depreciation expense was $39.3 million, $33.2 million and $29.4 million in 2015, 2014 and 2013, respectively.

In 2015, we incurred approximately $13 million of capital expenditures to complete the expansion of our mat manufacturing facility, located in Carencro, Louisiana, including a new research and development center, bringing our cumulative investment for this expansion project to approximately $46 million. In addition, we continued two capital investment projects announced in 2014 within the Fluids Systems segment. We invested approximately $20 million in a new fluid blending facility and distribution center located in Conroe, Texas, which will support the increasing demand for our proprietary fluid technologies, including our Evolution systems. This project was substantially completed in 2015 with the start-up of blending operations in early 2016. In addition, we are investing approximately $30 million to significantly expand existing capacity and upgrade the drilling fluids blending, storage and transfer capabilities in Fourchon, Louisiana, which serves the Gulf of Mexico deepwater market. This project is expected to be completed in 2016. Capital expenditures related to these two Fluids Systems projects were approximately $26 million in 2015.

In the fourth quarter of 2015, we recognized a $2.6 million charge reported in impairments and other charges related to assets at a Fluids Systems segment facility, following our decision to exit this facility.

Goodwill and other indefinite-lived intangible assets are tested for impairment annually as of November 1, or more frequently, if an indication of impairment exists. We determine any impairment of goodwill by comparing the carrying amounts of our reporting units with fair values, which we estimate using a combination of a market multiple and discounted cash flow approach. We also compare the aggregate fair values of our reporting units with our market capitalization. In the third quarter of 2015, primarily as a result of the ongoing weakness in commodity prices, further decreases in U.S. drilling activities, and increased expectations that the current weakness in U.S. drilling activities would persist for a longer period, along with a significant decline in the quoted market prices of our common stock, we considered these developments at that time to be an indicator of impairment that required us to complete an interim goodwill impairment evaluation. As such, during the third quarter of 2015, we estimated the fair values for each of our reporting units based on our current forecasts and expectations for market conditions at that time and determined that even though the estimated fair values for each reporting unit had decreased in 2015, each reporting unit’s fair value remained in excess of its net carrying value, and therefore, no impairment was required.

In the fourth quarter of 2015, we completed the annual evaluation of the carrying values of our goodwill and other indefinite-lived intangible assets as of November 1, 2015. As a result of the further decline in commodity prices and drilling activities in the fourth quarter, including the more prolonged projection of lower commodity prices and drilling activities, as well as the further decline in the quoted market prices of our common stock, we determined that the carrying value of our drilling fluids reporting unit exceeded its estimated fair value such that goodwill was potentially impaired. As a result, we completed the step two evaluation to measure the amount of goodwill impairment determining a full impairment of goodwill related to the drilling fluids reporting unit was required. As such, in the fourth quarter of 2015, we recorded a $70.7 million non-cash impairment charge to write-off the goodwill related to the drilling fluids reporting unit, which is included in impairments and other charges. In completing this annual evaluation as of November 1, 2015, we also determined that the Mats & Integrated Services reporting unit did not have a fair value below its net carrying value and therefore, no impairment was required.

Other intangible assets consist of the following:

Financing arrangements consisted of the following at December 31, 2015 and 2014:

(In thousands)	2015			2014

Less: current portion		(7,382	)		(11,648	)
Long-term portion	$	171,211		$	170,462

Our financing arrangements include $172.5 million of unsecured convertible senior notes (“Senior Notes”) and a $150.0 million revolving credit facility which, subject to the conditions contained therein can be increased to a maximum capacity of $275.0 million. At December 31, 2015, we had no outstanding borrowings under the revolving credit facility. Additionally, our foreign operations had $7.4 million outstanding under lines of credit and other borrowings. The Senior Notes bear interest at a rate of 4.0% per year, payable semi-annually in arrears on April 1 and October 1 of each year. Holders may convert the Senior Notes at their option at any time prior to the close of business on the business day immediately preceding the October 1, 2017 maturity date. The conversion rate is initially 90.8893 shares of our common stock per $1,000 principal amount of Senior Notes (equivalent to an initial conversion price of $11.00 per share of common stock), subject to adjustment in certain circumstances. Upon conversion, the Senior Notes will be settled in shares of our common stock. In 2015, holders converted an insignificant amount of Senior Notes into shares of our common stock. We may not redeem the Senior Notes prior to their maturity date. In February 2016, we repurchased $11.2 million of our convertible senior notes in the open market for $9.2 million under our existing Board authorized repurchase program

and will recognize a gain in 2016 for the difference in the amount paid and the net carrying value of the extinguished debt.

In March 2015, we entered into a Third Amended and Restated Credit Agreement (the “Credit Agreement”) which provides for a $200 million revolving loan facility available for borrowings and letters of credit and expires in March 2020. In December 2015, we entered into a First Amendment to Third Amended and Restated Credit Agreement (“Amendment”) decreasing the revolving loan facility to $150 million, modifying certain financial covenants through the first quarter of 2017, and modifying the borrowing cost and fee provisions. The Credit Agreement has a springing maturity date that will accelerate the maturity of the credit facility to June 2017 if the Senior Notes have not either been repurchased, redeemed, converted and/or refinanced in full or the Company has not provided sufficient funds to an escrow agent to repay the Senior Notes in full on their maturity date. Under the terms of the Amendment, we can elect to borrow at a variable interest rate either based on LIBOR plus a margin based on our consolidated leverage ratio, ranging from 175 to 325 basis points, or at a variable interest rate based on the greatest of: (a) prime rate, (b) the federal funds rate in effect plus 50 basis points, or (c) the Eurodollar rate for a Eurodollar Loan with a one-month interest period plus 100 basis points, in each case plus a margin ranging from 75 to 225 basis points based on our consolidated leverage ratio. The applicable margins on LIBOR borrowings and Eurodollar borrowings on December 31, 2015 were 250 and 150 basis points, respectively. In addition, we are required to pay a commitment fee on the unused portion of the Credit Agreement, as amended, ranging from 37.5 to 50.0 basis points, based on our consolidated leverage ratio. The applicable commitment fee on December 31, 2015 was 37.5 basis points. The Credit Agreement contains customary financial and operating covenants, including a consolidated leverage ratio, a senior secured leverage ratio and an interest coverage ratio. The Credit Agreement also limits the payment of dividends on our common stock, the repurchase of our common stock and the conversion, redemption, defeasance or refinancing of the Senior Notes.

Pursuant to the Amendment, a temporary increase has been made to the consolidated leverage ratio covenant, increasing the ratio from 4.0:1.0 to 5.5:1.0 through 2016, then reducing to 4.5 in the first quarter of 2017, and returning to 4.0 thereafter. During the same period, the senior secured leverage ratio covenant is being reduced from 3.0:1.0 to 2.0:1.0 through 2016, then increasing to 2.5 in the first quarter of 2017, and returning to 3.0 thereafter. The calculation for these two ratios has also been modified to allow for up to $10 million of adjustments for severance costs, as well as foreign exchange impacts related to our Brazilian intercompany financial restructuring. At December 31, 2015, we have not utilized any of this $10 million adjustment allowance in determining the available borrowing capacity under the Credit Agreement or in the calculation of the financial ratios disclosed below.

At December 31, 2015, considering our current financial covenant ratios disclosed below, we had $16.7 million of borrowing capacity available under our Credit Agreement, without taking into account any available adjustments described above, which, if utilized, could increase the availability under our Credit Agreement. The Credit Agreement is a senior secured obligation, secured by first liens on all of our U.S. tangible and intangible assets. Additionally, the Credit Agreement is guaranteed by certain of our U.S. subsidiaries and a portion of the capital stock of our non-U.S. subsidiaries has also been pledged as collateral.

The financial covenants under our Credit Agreement following the December 2015 Amendment and the applicable ratios as of the dates indicated, are as follows:

	Covenant		December 31, 2015		September 30, 2015		December 31, 2014

Interest coverage ratio	2.50	minimum		3.90		9.62		17.63

Consolidated leverage ratio	5.50	maximum		5.03		2.07		1.12

Senior Secured leverage ratio	2.00	maximum		0.21		0.07		0.19

We were in compliance with all financial covenants as of December 31, 2015. However, continued compliance with our covenants, particularly the consolidated leverage ratio, is largely dependent on our ability to generate sufficient levels of EBITDA, as defined in the Credit Agreement, as amended, or reduce our debt levels. Based upon our current and expected financial condition, and our forecasted results of operations, we anticipate having difficulty remaining in compliance with the financial covenants as of the end of the first quarter and throughout 2016, particularly if market conditions deteriorate further. As a result, we have initiated discussions with our lead bank in an effort to explore our options, which may include a waiver or amendment to our Credit Agreement. Any waiver or amendment to the Credit Agreement may increase the cost of our borrowings and impose additional limitations over certain types of activities. However, there is no certainty that we will be able to obtain any such relief. Any failure to comply with such financial covenants would result in an event of default under our Credit Agreement if we are unable to obtain a waiver or amendment on a timely basis. While no amounts are currently outstanding under our Credit Agreement, an event of default would prevent us from borrowing under our Credit Agreement and could result in our having to immediately repay all amounts outstanding, if any, under our Credit Agreement. In the event any outstanding amounts of indebtedness in excess of $25 million are accelerated, this could also cause a default under our Senior Notes.

At December 31, 2015, we had letters of credit issued and outstanding which totaled $14.8 million that are collateralized by $15.5 million in restricted cash. Additionally, our foreign operations had $7.4 million outstanding under lines of credit and other borrowings, as well as $10.4 million outstanding in letters of credit and other guarantees with certain letters of credit that are collateralized by $2.0 million in restricted cash. At December 31, 2015, this restricted cash totaling $17.5 million was included in other current assets in the accompanying balance sheet.

Our foreign subsidiaries, primarily those in Italy, Brazil and India, maintain local credit arrangements consisting primarily of lines of credit with several banks, which are renewed on an annual basis. We utilize local financing arrangements in our foreign operations in order to provide short-term local liquidity needs, as well as to reduce the net investment in foreign operations subject to foreign currency risk. Advances under these short-term credit arrangements are typically based on a percentage of the subsidiary’s accounts receivable or firm contracts with certain customers. The weighted average interest rate under these arrangements was 14.9% and 15.1% on total outstanding balances of $7.4 million and $11.4 million at December 31, 2015 and 2014, respectively.

We incurred net interest expense of $9.1 million, $10.4 million, and $11.3 million for the years ended December 31, 2015, 2014 and 2013, respectively. Capitalized interest was $1.1 million and $0.8 million for the years ended December 31, 2015 and 2014, respectively. Scheduled repayment of all long-term debt as of December 31, 2015 is $172.5 million in 2017.

Note 7 — Fair Value of Financial Instruments and Concentrations of Credit Risk

Fair Value of Financial Instruments

Our financial instruments include cash and cash equivalents, receivables, payables and debt. We believe the carrying values of these instruments, with the exception of our Senior Notes, approximated their fair values at December 31, 2015 and December 31, 2014. The estimated fair value of our Senior Notes was $154.4 million at December 31, 2015 and $192.3 million at December 31, 2014, based on quoted market prices at these respective dates.

Concentrations of Credit Risk

Financial instruments that potentially subject us to significant concentrations of credit risk consist principally of cash, trade accounts and notes receivable. At December 31, 2015, substantially all of our cash deposits are held in accounts at numerous financial institutions across the various regions that we operate in. A majority of the cash is held in accounts that maintain deposit ratings of P-1 by Moody’s, A-1 by Standard and Poor’s, and F1 by Fitch. As part of our investment strategy, we perform periodic evaluations of the relative credit standing of these financial institutions.

Accounts Receivable

Accounts receivable at December 31, 2015 and 2014 include the following:

(In thousands)		2015			2014

Gross trade receivables	$	159,119		$	299,962

Other receivables		21,834			22,838

Total receivables, net	$	206,364		$	318,600

At December 31, 2015, income tax receivables includes approximately $29 million related to our decision to amend prior U.S. federal income tax returns and request a refund for the carryback of the U.S. federal tax losses incurred in 2015. Other receivables include $10.4 million and $13.3 million for value added, goods and service taxes related to foreign jurisdictions as of December 31, 2015 and 2014, respectively. In addition, other receivables at both December 31, 2015 and 2014 include $8.0 million associated with the 2014 sale of the Environmental Services business that is held in escrow as described in Note 2 above.

We derive a significant portion of our revenues from companies in the E&P industry, and our customer base is highly concentrated in mid-sized and international oil companies as well as government-owned or government-controlled oil companies operating in the markets that we serve. During the years ended December 31, 2015, 2014 and 2013, revenues from our 20 largest customers represented approximately 49%, 40% and 50%, respectively, of our consolidated revenues from continuing operations, although no single customer accounted for more than 10% of our consolidated revenues.

We maintain an allowance for doubtful accounts based upon the expected collectability of accounts receivable. Changes in this allowance for 2015, 2014 and 2013 related to continuing operations, was as follows:

(In thousands)		2015			2014		2013
Balance at beginning of year	$	5,458		$	4,142	$	3,950
Provision for uncollectible accounts		1,886			1,246		309
Write-offs, net of recoveries		(155	)		70		(117	)
Balance at end of year	$	7,189		$	5,458	$	4,142

The Consolidated Statements of Cash Flows included in this Item 8 of these Financial Statements and Supplementary Data also includes an insignificant provision for uncollectible accounts related to the Environmental Services business that is classified as discontinued operations.

The Company’s effective tax rate in 2015 was primarily impacted by the impairment of non-deductible goodwill. In 2015, the income tax provision also includes a $4.4 million benefit associated with the forgiveness of certain inter-company balances due from our Brazilian subsidiary and a $2.2 million benefit from the release of U.S. tax reserves, following the expiration of statutes of limitation. In addition, the 2015 income tax provision includes a $4.6 million charge for increases to the valuation allowance for certain deferred tax assets, primarily related to our Australian subsidiary and certain U.S. state net operating losses, which may not be realized, as well as a $1.6 million charge relating to management’s election to carry back the 2015 U.S. federal tax losses to prior years.

Temporary differences and carryforwards which give rise to deferred tax assets and liabilities at December 31, 2015 and 2014 are as follows:

(In thousands)	2015			2014

Deferred tax assets:
Net operating losses	$	14,800		$	15,097
Capitalized inventory costs		6,717			4,250

Deferred tax liabilities:
Accelerated depreciation and amortization		(38,034	)		(40,308	)
Tax on unremitted earnings		(7,181	)		(6,680	)
Other		(2,856	)		(3,025	)
Total deferred tax liabilities		(48,071	)		(50,013	)

Total net deferred tax liabilities	$	(24,547	)	$	(25,930	)

Non current deferred tax liabilities		(26,368	)		(27,787	)
Net deferred tax liabilities	$	(24,547	)	$	(25,930	)

For state income tax purposes, we have net operating loss carryforwards (“NOLs”) of approximately $212.8 million available to reduce future state taxable income. These NOLs expire in varying amounts beginning in year 2018 through 2030. Foreign NOLs of approximately $14.2 million are available to reduce future taxable income, some of which expire beginning in 2016.

The realization of our net deferred tax assets is dependent on our ability to generate taxable income in future periods. At December 31, 2015 and December 31, 2014, we have recorded a valuation allowance in the amount of $16.8 million and $15.4 million, respectively, primarily related to certain U.S. state and foreign NOL carryforwards, including Brazil and Australia, which may not be realized.

Unremitted foreign earnings permanently reinvested abroad upon which deferred income taxes have not been provided aggregated approximately $142.8 million and $133.3 million at December 31, 2015 and 2014, respectively. It is not practicable to determine the amount of federal income taxes, if any, that might become due if such earnings are repatriated. We have the ability and intent to leave these foreign earnings permanently reinvested abroad.

We file income tax returns in the United States and several non-U.S. jurisdictions and are subject to examination in the various jurisdictions in which we file. We are no longer subject to income tax examinations for U.S. federal and substantially all state jurisdictions for years prior to 2011 and for substantially all foreign jurisdictions for years prior to 2007. We are not currently under examination by any United States federal or state tax authorities, however, we are under examination by various tax authorities in other countries. We fully cooperate with all audits, but defend existing positions vigorously. These audits are in various stages of completion and certain foreign jurisdictions have challenged the amount of taxes due for certain tax periods. We evaluate the potential exposure associated with various filing positions and record a liability for tax contingencies as circumstances warrant. Although we believe all tax positions are reasonable and properly reported in accordance with applicable tax laws and regulations in effect during the periods involved, the final determination of tax audits and any related litigation could be materially different than that which is reflected in historical income tax provisions and tax contingency accruals.

A reconciliation of the beginning and ending provision for uncertain tax positions is as follows:

(In thousands)	2015			2014		2013

Balance at January 1	$	3,786		$	2,175	$	2,753
Additions (reductions) for tax positions of prior years		(95	)		1,604		(650	)
Additions for tax positions of current year		-			7		72
Reductions for settlements with tax authorities		(575	)		-		-
Reductions for lapse of statute of limitations		(2,697	)		-		-
Balance at December 31	$	419		$	3,786	$	2,175

Approximately $0.1 million of unrecognized tax benefits at December 31, 2015, if recognized, would favorably impact the effective tax rate. In 2015, we recognized a $2.2 million benefit to the income tax provision relating to uncertain tax positions for which the applicable statutes of limitation expired.

The Company recognizes accrued interest and penalties related to uncertain tax positions in operating expenses. During the year ended December 31, 2015 and 2014, the Company recognized approximately $0.1 million and $0.4 million, respectively in interest and penalties. In 2013, there was no interest and penalties recognized. The Company had approximately $0.1 million and $0.4 million for interest and penalties accrued at December 31, 2015 and 2014, respectively.

Repurchase program

In April 2013, our Board of Directors approved a share repurchase program that authorizes the Company to purchase up to $50.0 million of its outstanding shares of common stock. This authorization was subsequently increased to $100.0 million in February 2014. In September 2015, our Board of Directors expanded the repurchase program to include the repurchase of our convertible senior notes, in addition to outstanding shares of common stock. The repurchase program has no specific term. The Company may repurchase shares or convertible senior notes in the open market or as otherwise determined by management, subject to market conditions, business opportunities, limiatations under our existing Credit Agreement and other factors. Repurchases are expected to be funded from operating cash flows and available cash on-hand. Subject to continued covenant compliance, funds under our existing Credit Agreement could also be available for such repurchases. As part of the share repurchase program, the Company’s management has been authorized to establish trading plans under Rule 10b5-1 of the Securities Exchange Act of 1934.

There were no repurchases under the program during 2015. During the years ended December 31, 2014 and 2013, we repurchased shares of the Company’s common stock under this program totaling 4,317,278 and 562,341 shares, respectively for an average price per share, including commissions, of $11.72 and $11.94, respectively. As of December 31, 2015, there was $42.7 million of authorization remaining under the program.

In February 2016, we repurchased $11.2 million of our convertible senior notes in the open market for $9.2 million. This repurchase was made under our existing Board authorized repurchase program discussed above. As of February 26, 2016, we had $33.5 million of authorization remaining under the program.

Note 11 — Stock Based Compensation and Other Benefit Plans

The following describes stockholder approved plans utilized by the Company for the issuance of stock based awards.

2014 Non-Employee Directors’ Restricted Stock Plan

In May 2014, our stockholders approved the 2014 Non-Employee Directors’ Restricted Stock Plan (the “2014 Director Plan”) which authorizes grants of restricted stock to non-employee directors based on a pre-determined dollar amount on the date of each annual meeting of stockholders. The pre-determined dollar amount for determining the number of restricted shares granted is subject to change by the Board of Directors or its committee but is initially set at $150,000 for each non-employee director, except for the Chairman of the Board who will receive an annual grant of restricted shares equal to $170,000. Each restricted share granted to a non-employee director vests in full on the earlier of the day prior to the next annual meeting of stockholders following the grant date or the first anniversary of the grant. During 2015, non-employee directors received shares of restricted stock totaling 102,218 shares at a weighted average fair value on the date of grant of $9.00 per share.

The maximum number of shares of common stock issuable under the 2014 Director Plan is 1,000,000 leaving 815,933 shares available for grant as of December 31, 2015.

2015 Equity Incentive Plan

In May 2015, our stockholders approved the 2015 Employee Equity Incentive Plan (“2015 Plan”), pursuant to which the Compensation Committee of our Board of Directors (“Compensation Committee”) may grant to key employees, including executive officers and other corporate and divisional officers, a variety of forms of equity-based compensation, including options to purchase shares of common stock, shares of restricted common stock, restricted stock units, stock appreciation rights, other stock-based awards, and performance-based awards. The maximum number of shares of common stock issuable under the 2015 Plan is 6,000,000. Under the 2015 Plan, grants of stock options and stock appreciation rights will reduce the number of available shares on a 1 to 1 basis, while full value awards will reduce the number of available shares on a 1.85 to 1 basis. At December 31, 2015, 2,975,525 shares remained available for award under the 2015 Plan.

Prior to approval of the 2015 Plan, equity-based compensation was provided pursuant to the 2006 Equity Incentive Plan (“2006 Plan”). No additional grants of equity-based compensation may be granted under the 2006 Plan following approval of the 2015 Plan, however, unexpired options and other awards previously granted continue in effect in accordance with their terms until they vest or are otherwise exercised or expire.

The Compensation Committee approves the granting of all stock based compensation to employees, utilizing shares available under the 2015 Plan. Activity under each of these programs is described below.

Stock Options & Cash-Settled Stock Appreciation Rights

Stock options granted by the Compensation Committee are generally granted with a three year vesting period and a term of ten years. During 2015, 695,698 options were granted with a three year vesting period and a ten year term. The exercise price of each stock option granted was equal to the fair market value on the date of grant.

The following table summarizes activity for our outstanding stock options for the year ended December 31, 2015:

	Shares			Weighted- Average Exercise Price		Weighted- Average Remaining Contractual Life (Years)		Aggregate Intrinsic Value

Outstanding at beginning of period		3,342,015		$	7.67
Granted		695,698			9.00
Exercised		(104,339	)		5.30
Expired or cancelled		(45,541	)		8.94
Outstanding at end of period		3,887,833		$	7.96		6.20	$	877,383

Vested or expected to vest at end of period		3,831,985		$	7.93		6.16	$	877,383
Options exercisable at end of period		2,715,043		$	7.10		5.06	$	877,383

We estimated the fair value of options granted on the date of grant using the Black-Scholes option-pricing model, with the following weighted average assumptions:

	Year Ended December 31,
	2015			2014			2013

Risk-free interest rate		1.57	%		1.53	%		1.02	%
Expected life of the option in years		5.22			5.22			5.22
Expected volatility		47.3	%		48.6	%		53.7	%
Dividend yield		-			-			-

The risk-free interest rate is based on the implied yield on a U.S. Treasury zero-coupon issue with a remaining term equal to the expected term of the option. The expected life of the option is based on observed historical patterns. The expected volatility is based on historical volatility of the price of our common stock. The dividend yield is based on the projected annual dividend payment per share divided by the stock price at the date of grant, which is zero because we have not paid dividends for several years and do not expect to pay dividends in the foreseeable future.

The following table summarizes information about the weighted-average exercise price and the weighted-average grant date fair value of stock options granted:

	Year Ended December 31,
	2015		2014		2013

Weighted-average exercise price of the stock on the date of grant	$	9.00	$	11.20	$	11.43
Weighted-average grant date fair value on the date of grant	$	3.91	$	4.97	$	5.42

All stock options granted for the years ended December 31, 2015, 2014 and 2013 reflected an exercise price equal to the market value of the stock on the date of grant.

The total intrinsic value of options exercised was $0.3 million, $3.2 million and $6.1 million for the years ended December 31, 2015, 2014 and 2013, while cash from option exercises totaled $0.6 million, $3.4 million and $8.3 million, respectively.

The following table summarizes activity for outstanding cash-settled stock appreciation rights for the year-ended December 31, 2015:

	Rights

Outstanding at beginning of period		107,133
Exercised		-
Expired or cancelled		(4,000	)
Outstanding at end of period		103,133

Exercisable at end of period		103,133

During 2015, there were no additional grants of cash-settled stock appreciation rights. The remaining outstanding cash-settled stock appreciation rights, if exercised, will ultimately be settled in cash for the difference between market value of our outstanding shares at the date of exercise, and $7.89. As such, the projected cash settlement is adjusted each period based upon the ending fair market value of the underlying stock. At December 31, 2015, the fair market value of each cash-settled stock appreciation right was $1.04, resulting in a liability of $0.1 million.

Total compensation cost recognized for stock options and cash-settled stock appreciation rights during the years ended December 31, 2015, 2014 and 2013 was $2.6 million, $2.6 million and $3.3 million, respectively. For the years ended December 31, 2015, 2014 and 2013, we recognized tax benefits resulting from the exercise of stock options totaling $0.1 million, $1.0 million and $1.9 million, respectively.

Performance-Based Restricted Stock Units & Cash-Settled Performance-Based Restricted Stock Units

The Compensation Committee may use various business criteria to set the performance objectives for awards of performance-based restricted stock units. During 2015, 2014 and 2013, performance-based awards were awarded to executive officers. The performance-based restricted stock units will be settled in shares of common stock and will be based on the relative ranking of the Company’s total shareholder return (“TSR”) as compared to the TSR of the Company’s designated peer group over a three year period. During 2015, a total of 136,881 performance-based restricted stock units at target were granted with the payout of shares for each executive ranging from 0%-150% of target. The performance period began June 1, 2015 and ends May 31, 2018, with the ending TSR price being equal to the average closing price of our shares over the 30-calendar days ending May 31, 2018. During 2014, a total of 110,497 performance-based restricted stock units at target were granted with the payout of shares for each executive ranging from 0%-150% of target.

Restricted Stock Awards and Units

Time-vested restricted stock awards and restricted stock units are periodically granted to key employees, including grants for employment inducements, as well as to members of our Board of Directors. Employee awards provide for vesting periods ranging from three to four years. Non-employee director grants vest in full on the earlier of the day prior to the next annual meeting of stockholders following the grant date or the first anniversary of the grant. Upon vesting of these grants, shares are issued to award recipients.

The following tables summarize the activity for our outstanding time-vested restricted stock awards and restricted stock units for the year-ended December 31, 2015.

Nonvested Shares (Time-Vesting)	Shares			Weighted-Average Grant Date Fair Value

Total compensation cost recognized for restricted stock awards and restricted stock units was $10.1 million, $8.6 million and $6.7 million for the years ended December 31, 2015, 2014 and 2013 respectively. Total unrecognized compensation cost at December 31, 2015 related to restricted stock awards and restricted stock units is approximately $14.0 million which is expected to be recognized over the next 1.9 years. During the years ended December 31, 2015, 2014 and 2013, the total fair value of shares vested was $8.1 million, $9.0 million and $9.5 million, respectively.

For the years ended December 31, 2015, 2014 and 2013, we recognized tax benefits resulting from the vesting of restricted share awards totaling $2.0 million, $2.8 million and $3.0 million, respectively.

Defined Contribution Plan

Substantially all of our U.S. employees are covered by a defined contribution plan (“401(k) Plan”). Employees may voluntarily contribute up to 50% of compensation, as defined in the 401(k) Plan. Participants’ contributions, up to 3% of compensation, are matched 100% by us, and the participants’ contributions, from 3% to 6% of compensation, are matched 50% by us. Under the 401(k) Plan, our cash contributions were $3.2 million, $3.6 million and $3.4 million in 2015, 2014 and 2013, respectively. In response to the continuing decline in activity in early 2016, we have initiated additional cost reduction programs which include the temporary elimination of our 401(k) matching contribution beginning in March 2016.

Segment Reporting Disclosure [Text Block]

Note 12 — Segment and Related Information

Our Company consists of two reportable segments, which offer different products and services to a relatively homogenous customer base. The reportable segments include: Fluids Systems and Mats and Integrated Services. Intersegment revenues are generally recorded at cost for items which are included in inventory of the purchasing segment, and at standard markups for items which are included in cost of revenues of the purchasing segment. All intersegment revenues and related profits have been eliminated.

Fluids Systems —

Our Fluids Systems business offers customized solutions including highly technical drilling projects involving complex subsurface conditions, such as horizontal, directional, geologically deep or deep water drilling. These projects require increased monitoring and critical engineering support of the fluids system during the drilling process. We provide drilling fluids products and technical services to markets in North America, EMEA, Latin America, and the Asia Pacific regions.

We also have industrial mineral grinding operations for barite, a critical raw material in drilling fluids products, which serve to support our activity in the North American drilling fluids market. We grind barite and other industrial minerals at four facilities, including locations in Texas, Louisiana and Tennessee. We use the resulting products in our drilling fluids business, and also sell them to third party users, including other drilling fluids companies. We also sell a variety of other minerals, principally to third party industrial (non-oil and gas) markets.

Mats and Integrated Services —

We manufacture our DURA-BASE

Advanced Composite Mats for use in our rental operations as well as for third party sales. Our mats provide environmental protection and ensure all-weather access to sites with unstable soil conditions. We sell composite mats direct to customers in areas around the world where we do not maintain an infrastructure for our mat rental activities. In addition, we provide mat rentals to E&P customers in the Northeast U.S., onshore U.S. Gulf Coast, and Rocky Mountain Regions, and to non-E&P customers in the U.S., Canada and the United Kingdom. We also offer location construction and related well site services to E&P customers in the Gulf Coast Region.

Historically, our marketing efforts for the sale of composite mats remained focused in principal oil and gas industry markets outside the U.S., as well as markets outside the E&P sector in the U.S. and Europe. We believe these mats have worldwide applications outside our traditional oilfield market, primarily in infrastructure construction, maintenance and upgrades of pipelines and electric utility transmission lines, and as temporary roads for movement of oversized or unusually heavy loads. In late 2013, we announced plans to significantly expand our manufacturing facility, in order to support our efforts to expand our markets globally. This project was completed in 2015, which nearly doubled our manufacturing capacity and significantly expanded our research and development capabilities.

In response to the significant declines in activity, we initiated cost reduction programs in the first quarter of 2015, including workforce reductions, reduced discretionary spending, and temporary salary freezes for substantially all employees, including executive officers, and have continued these efforts throughout 2015. In September 2015, we also initiated a voluntary retirement program with certain eligible employees in the United States for retirement dates ranging from the fourth quarter of 2015 through the third quarter of 2016. As part of these cost reduction programs, we have reduced our North American employee base by 436 (approximately 34%) in 2015 in addition to eliminating substantially all contract positions. As a result of these termination programs, our 2015 operating results include $8.2 million of charges associated with employee termination costs with $5.7 million reported in cost of revenues and $2.5 million reported in selling, general and administrative expenses. The employee termination costs include $7.2 million in Fluids Systems, $0.7 million in Mats and Integrated Services and $0.3 million in our corporate office. Accrued employee termination costs at December 31, 2015 are $3.3 million and are expected to be substantially paid in the first half of 2016. Additional employee termination costs of $0.7 million associated with the voluntary retirement program will be recognized in 2016.

During the fourth quarter of 2015, a total of $80.5 million of charges were included in operating loss for the reduction in value of certain assets and the pending resolution of certain wage and hour litigation claims. The Fluids Systems segment operating results include $75.5 million of these charges including a $70.7 million non-cash impairment of goodwill, a $2.6 million non-cash impairment of assets, following our decision to exit a facility, and a $2.2 million charge to reduce the carrying value of diesel-based drilling fluid inventory. In addition, corporate office expenses include a $5.0 million charge for the pending resolution of certain wage and hour litigation claims and related costs. In our 2015 consolidated statement of operations, a total of $78.3 million of these charges are reported in impairments and other charges with the $2.2 million charge for the write-down of inventory being reported in cost of revenues.

The Consolidated Statements of Cash Flows included in this Item 8 of these Financial Statements and Supplementary Data include $0.9 million and $4.4 million in depreciation and amortization expense and capital expenditures of $1.0 million and $1.7 million for 2014 and 2013, respectively, related to the Environmental Services business sold in 2014 that are classified as discontinued operations.

The following table sets forth geographic information for our operations. Revenues by geographic location are determined based on the operating location from which services are rendered or products are sold.

Note 14 — Commitments and Contingencies

In the ordinary course of conducting our business, we become involved in litigation and other claims from private party actions, as well as judicial and administrative proceedings involving governmental authorities at the federal, state and local levels.

Wage and Hour Litigation

During the second quarter of 2014, a lawsuit was filed by Jesse Davida, a former employee, in Federal Court in Texas against Newpark Drilling Fluids LLC, alleging violations of the Fair Labor Standards Act (“FLSA”). The plaintiff seeks damages and penalties for the Company’s alleged failure to: properly classify its field service employees as “non-exempt” under the FLSA; and pay them on an hourly basis (including overtime). The plaintiff seeks recovery on his own behalf, and seeks certification of a class of similarly situated employees. The Court conditionally certified a class of plaintiffs as those working as fluid service technicians for Newpark Drilling Fluids for the prior three years. Notification was given to 658 current and former fluid service technician employees of Newpark regarding this litigation and those individuals were given the opportunity to “opt-in” to the Davida litigation. The opt-in period closed in early May of 2015 and a total of 91 individuals joined the Davida litigation. Counsel for the plaintiffs moved to add state law class action claims for current and former fluid service technicians that worked for Newpark Drilling Fluids in New York, North Dakota, Ohio and Pennsylvania. The Court granted the motion, but gave Newpark the right to file a motion to dismiss these state law claims, and that motion is pending. Among other reasons, we sought dismissal of those state law claims on the basis that an insufficient number of employees are located in those states to support a class action. We expect that the effect of the additional state law claims (excluding New York and Ohio claims) would be to include in the litigation approximately 48 current and former fluid service technicians who worked in Pennsylvania, and approximately 41 current and former fluid service technicians who worked in North Dakota. Discovery is in process with the trial currently being scheduled for September 2016.

A second case was filed by Josh Christensen in the fourth quarter of 2014, in Federal Court in Texas alleging that individuals treated as independent contractors should have been classified as employees and, as such, are entitled to assert claims for alleged violations of the FLSA (similar to the claims asserted in the

Davida

matter). Five additional plaintiffs joined this litigation after it was filed. In March of 2015, the Court denied the plaintiffs’ motion for conditional class certification. Counsel for the plaintiffs did not appeal that ruling and have now filed individual cases for each of the original opt-in plaintiffs plus two new plaintiffs, leaving a total of eight independent contractor cases pending. Preliminary discovery has occurred in these cases.

In the fourth quarter of 2015, the same counsel representing the plaintiff’s in

Davida

and the

Christians

-related cases filed two additional individual FLSA cases on behalf of former fluid service technician employees. These cases are similar in nature to the

Davida

case discussed above.

Beginning in November 2015, we engaged in settlement discussions with counsel for the plaintiffs in the pending wage and hour litigation cases described above. Following mediation in January of 2016, the parties reached an agreement to settle all of the pending matters, subject to a number of conditions, including approval by the Court in the

Davida

case, and the dismissal of the other FLSA cases (

Christiansen

-related lawsuits and individual FLSA cases). Subject to these conditions, current and former fluid service technician employees that are eligible for the settlement will be notified of the pending resolution and given an opportunity to participate in the settlement. The amount paid to any eligible individual will vary based on a formula that takes into account the number of workweeks and salary for the individual during the time period covered by the settlement (which can vary based upon several factors). Any eligible individual that elects to participate in the settlement will release all wage and hour claims against the Company. As a result of the settlement negotiations, we recognized a $5.0 million charge in the fourth quarter of 2015 related to the pending resolution of these wage and hour litigation claims, which is included in impairments and other charges. We expect to fund the settlement amount in the first half of 2016, subject to the conditions described above. The settlement fund will be administered by a third party who will make payments to eligible individuals that elect to participate, in accordance with a formula incorporated into the pending settlement agreement. In addition, under the terms of the pending settlement agreement, if settlement funds remain after all payments are made to eligible individuals that elect to participate in the settlement, such excess amount will be shared by the participating individuals and Newpark Drilling Fluids. The amount of excess funds, if any, is not currently determinable.

Escrow Claims Related to Sale of Environmental Services Business

Under the terms of the March 2014 sale of the Environmental Services business to Ecoserv, LLC (“Ecoserv”), $8 million of the sales price was withheld and placed in an escrow account to satisfy claims for possible breaches of representations and warranties contained in the sale agreement. For the amount withheld in escrow, $4 million was scheduled for release to Newpark at each of the nine-month and 18-month anniversary of the closing. In December, 2014, we received a letter from counsel for Ecoserv asserting that we had breached certain representations and warranties contained in the sale agreement; including failing to disclose service work performed on injection wells and increased barge rental costs. The letter indicated that Ecoserv expected the costs associated with these claims to exceed the escrow amount. Following a further exchange of letters, in July of 2015, we filed a declaratory judgment action against Ecoserv in state court in Harris County, Texas, seeking release of the escrow funds. Thereafter, Ecoserv filed a counterclaim seeking recovery of the escrow funds based on the alleged breach of representations and warranties. Ecoserv also alleges that we committed fraud in connection with the sale transaction. We believe there is no basis in the agreement or on the facts to support the claims asserted by Ecoserv and intend to vigorously defend our position, while pursuing release of the entire $8 million escrow. Discovery has commenced between the parties.

Leases

We lease various manufacturing facilities, warehouses, office space, machinery and equipment, including transportation equipment, under operating leases with remaining terms ranging from one to eleven years, with various renewal options. Substantially all leases require payment of taxes, insurance and maintenance costs in addition to rental payments. Total rental expenses for all operating leases were approximately $22.6 million, $25.5 million and $24.5 million in 2015, 2014 and 2013, respectively.

Future minimum payments under non-cancelable operating leases, with initial or remaining terms in excess of one year are included in the table below. Future minimum payments under capital leases are not significant.

Other

In conjunction with our insurance programs, we had established letters of credit in favor of certain insurance companies in the amount of $3.3 million and $3.5 million at December 31, 2015 and 2014, respectively. We also had $0.4 million and $0.4 million in guarantee obligations in connection with facility closure bonds and other performance bonds issued by insurance companies outstanding as of December 31, 2015 and 2014, respectively.

Other than normal operating leases for office and warehouse space, rolling stock and other pieces of operating equipment, we do not have any off-balance sheet financing arrangements or special purpose entities. As such, we are not materially exposed to any financing, liquidity, market or credit risk that could arise if we had engaged in such financing arrangements.

We are self-insured for health claims, subject to certain “stop loss” insurance policies. Claims in excess of $250,000 per incident are insured by third-party insurers. We had accrued liabilities of $1.0 million and $1.8 million for unpaid claims incurred, based on historical experience at December 31, 2015 and 2014, respectively. Substantially all of these estimated claims are expected to be paid within six months of their occurrence.

We are self-insured for certain workers’ compensation, auto and general liability claims up to a certain policy limit. Claims in excess of $750,000 are insured by third-party reinsurers. At December 31, 2015 and 2014, we had accrued liabilities of $2.5 million and $2.4 million, respectively, for the uninsured portion of claims.

We maintain accrued liabilities for asset retirement obligations, which represent obligations associated with the retirement of tangible long-lived assets that result from the normal operation of the long-lived asset. Our asset retirement obligations primarily relate to required expenditures associated with owned and leased facilities. Upon settlement of the liability, a gain or loss for any difference between the settlement amount and the liability recorded is recognized. As of December 31, 2015 and 2014, we had accrued asset retirement obligations of $0.8 million and $0.6 million, respectively.
