Significant Accounting Policies [Abstract]

Significant Accounting Policies

NOTE 1—SIGNIFICANT ACCOUNTING POLICIES

Business Operations: MRC Global Inc. is a holding company headquartered in Houston, Texas. Our wholly owned subsidiaries are global distributors of pipe, valves, fittings (“PVF”) and other infrastructure products and services across each of the upstream (exploration, production and extraction of underground oil and gas), midstream (gathering and transmission of oil and gas, gas utilities, and the storage and distribution of oil and gas) and downstream (crude oil refining and petrochemical processing) sectors. We have branches in principal industrial, hydrocarbon producing and refining areas throughout the United States, Canada, Europe, Asia, Australasia, the Middle East and Caspian. Our products are obtained from a broad range of suppliers.

Basis of Presentation: The accompanying consolidated financial statements include the accounts of MRC Global Inc. and its wholly owned and majority owned subsidiaries (collectively referred to as the “Company” or by such terms as “we,” “our” or “us”). All material intercompany balances and transactions have been eliminated in consolidation.

Use of Estimates: The preparation of financial statements in conformity with the accounting principles generally accepted in the United States of America requires us to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenue and expenses during the reported period. We believe that our most significant estimates and assumptions are related to estimated losses on accounts receivable, the last-in, first-out (“LIFO”) inventory costing methodology, estimated net realizable value on excess and obsolete inventories, goodwill, intangible assets, deferred taxes and self-insurance programs. Actual results could differ materially from those estimates.

Cash Equivalents: We consider all highly liquid investments with maturities of three months or less at the date of purchase to be cash equivalents.

Allowance for Doubtful Accounts: We evaluate the adequacy of the allowance for losses on receivables based upon periodic evaluation of accounts that may have a higher credit risk using information available about the customer and other relevant data. This formal analysis is inherently subjective and requires us to make significant estimates of factors affecting doubtful accounts including customer specific information, current economic conditions, volume, growth and composition of the account, and other factors such as financial statements, news reports and published credit ratings. The amount of the allowance for the remainder of the trade balance is not evaluated individually but is based upon historical loss experience. Because this process is subjective and based on estimates, ultimate losses may differ from those estimates. Receivable balances are written off when we determine that the balance is uncollectible. Subsequent recoveries, if any, are credited to the allowance when received. The provision for losses on receivables is included in selling, general and administrative expenses in the accompanying consolidated statements of operations.

Inventories: Our inventories are valued at the lower of cost, principally LIFO, or market. We believe that the use of LIFO results in a better matching of costs and revenue. This practice excludes certain inventories, which are held outside of the United States, approximating $181 million and $187 million at December 31, 2019 and 2018, respectively, which are valued at the lower of weighted-average cost or net realizable value. Our inventory is substantially comprised of finished goods.

Reserves for excess and obsolete inventories are determined based on analyses comparing inventories on hand to sales activity over time. The reserve, which totaled $35 million and $40 million at December 31, 2019 and 2018, respectively, is the amount deemed necessary to reduce the cost of the inventory to its estimated net realizable value.

Debt Issuance Costs: We defer costs directly related to obtaining financing and amortize them over the term of the indebtedness on a straight-line basis. The use of the straight-line method does not produce results that are materially different from those which would result from the use of the effective interest method. These amounts are reflected in the consolidated statement of operations as a component of interest expense. Debt issuance costs associated with our Global ABL Facility are presented in other assets and totaled $2 million and $3 million at December 31, 2019 and 2018, respectively. Debt issuance costs associated with our Term Loan are presented as a reduction of the carrying amount of the debt liability and totaled $2 million at December 31, 2019 and 2018.

Property, Plant and Equipment: Land, buildings and equipment are stated on the basis of cost. For financial statement purposes, depreciation is computed over the estimated useful lives of such assets principally by the straight-line method; accelerated depreciation and cost recovery methods are used for income tax purposes. Leasehold improvements are amortized using the straight-line method over the shorter of the remaining lease term or the estimated useful life of the improvements. When assets are retired or otherwise disposed of, the cost and related accumulated depreciation are removed from the accounts and any gain or loss is reflected in income for the period. Maintenance and repairs are charged to expense as incurred.

Certain systems development costs related to the purchase, development and installation of computer software are capitalized and amortized over the estimated useful life of the related asset. Costs incurred prior to the development stage, as well as maintenance, training costs and general and administrative expenses are expensed as incurred.

Goodwill and Other Intangible Assets: Goodwill represents the excess of acquisition cost over the fair value of net assets acquired. Goodwill and intangible assets with indefinite useful lives are tested for impairment annually, or more frequently if circumstances indicate that impairment may exist. We evaluate goodwill for impairment at the reporting unit level. Within each reporting unit, we have elected to aggregate the component countries and regions into a single reporting unit based on their similar economic characteristics, products, customers, suppliers, methods of distribution and the manner in which we operate each reporting unit. We perform our annual tests for goodwill impairment as of October 1^st of each year, updating on an interim basis should indications of impairment exist.

The goodwill impairment test compares the carrying value of the reporting unit that has the goodwill with the estimated fair value of that reporting unit. To the extent the carrying value of a reporting unit is greater than its estimated fair value, a goodwill impairment charge is recorded for the difference, up to the carrying value of goodwill. Our impairment methodology uses discounted cash flow and multiples of cash earnings valuation techniques, acquisition control premium and valuation comparisons to similar businesses. Each of these methods involves Level 3 unobservable market inputs and require us to make certain assumptions and estimates regarding future operating results, the extent and timing of future cash flows, working capital, sales prices, profitability, discount rates and growth trends. While we believe that such assumptions and estimates are reasonable, the actual results may differ materially from the projected results.

Intangible assets with indefinite useful lives are tested for impairment annually or more frequently if circumstances indicate that impairment may exist. This test compares the carrying value of the indefinite-lived intangible assets with their estimated fair value. If the carrying value is more than the estimated fair value, impairment losses are recognized in an amount equal to the excess of the carrying value over the estimated fair value. Our impairment methodology uses discounted cash flow and estimated royalty rate valuation techniques. Each of these methods involves Level 3 unobservable market inputs and requires us to make certain assumptions and estimates regarding future operating results, sales prices, discount rates and growth trends. While we believe that such assumptions and estimates are reasonable, the actual results may differ materially from the projected results.

Other intangible assets primarily include trade names, customer bases and noncompetition agreements resulting from business acquisitions. Other intangible assets are recorded at fair value at the date of acquisition. Amortization is provided using the straight-line method over their estimated useful lives, ranging from two years to twenty years.

The carrying value of amortizable intangible assets is subject to an impairment test when events or circumstances indicate a possible impairment. When events or circumstances indicate a possible impairment, we assess recoverability from future operations using undiscounted cash flows derived from the lowest appropriate asset group. If the carrying value exceeds the undiscounted cash flows, an impairment charge would be recognized to the extent that the carrying value exceeds the fair value, which is determined based on a discounted cash flow analysis. While we believe that assumptions and estimates utilized in the impairment analysis are reasonable, the actual results may differ materially from the projected results. These impairments are determined prior to performing our goodwill impairment test.

Derivatives and Hedging: From time to time, we utilize interest rate swaps to reduce our exposure to potential interest rate increases. We have designated our interest rate swap as an effective cash flow hedge utilizing the guidance under ASU 2017-12. As such, the valuation of the interest rate swap is recorded as an asset or liability, and the gain or loss on the derivative is recorded as a component of other comprehensive income. Interest rate swap agreements are reported on the accompanying balance sheets at fair value utilizing observable Level 2 inputs such as yield curves and other market-based factors. We obtain dealer quotations to value our interest rate swap agreements. The fair value of our interest rate swap is estimated based on the present value of the difference between expected cash flows calculated at the contracted interest rates and the expected cash flows at current market interest rates.

We utilize foreign exchange forward contracts (exchange contracts) and options to manage our foreign exchange rate risks resulting from purchase commitments and sales orders. Changes in the fair values of our exchange contracts are based upon independent market quotes. We do not designate our exchange contracts as hedging instruments; therefore, we record our exchange contracts on the consolidated balance sheets at fair value, with the gains and losses recognized in earnings in the period of change.

Fair Value: We measure certain of our assets and liabilities at fair value on a recurring basis. Fair value is an exit price, representing the amount that would be received to sell an asset or be paid to transfer a liability in an orderly transaction between market participants. As such, fair value is a market-based measurement that is determined based on assumptions that market participants

would use in pricing an asset or a liability. A three-tier fair value hierarchy is established as a basis for considering such assumptions for inputs used in the valuation methodologies to measuring fair value:

Level 1: Quoted prices (unadjusted) in active markets for identical assets or liabilities that the entity has the ability to access at the measurement date.

Level 2: Significant observable inputs other than quoted prices included within Level 1 that are observable for the asset or liability, either directly or indirectly, such as quoted prices for similar assets or liabilities, quoted prices in markets that are not active, and other inputs that are observable or can be corroborated by observable market data.

Level 3: Significant unobservable inputs for the asset or liability. Unobservable inputs reflect our own assumptions about the assumptions that market participants would use in pricing an asset or liability (including all assumptions about risk).

Certain assets and liabilities are measured at fair value on a nonrecurring basis. Our assets and liabilities measured at fair value on a nonrecurring basis include property, plant and equipment, goodwill and other intangible assets. We do not measure these assets at fair value on an ongoing basis; however, these assets are subject to fair value adjustments in certain circumstances, such as when we recognize an impairment.

Our impairment methodology for goodwill and other indefinite-lived intangible assets uses both (i) a discounted cash flow analysis requiring certain assumptions and estimates to be made regarding the extent and timing of future cash flows, discount rates and growth trends and (ii) valuation based on our publicly traded common stock. As all of the assumptions employed to measure these assets and liabilities on a nonrecurring basis are based on management’s judgment using internal and external data, these fair value determinations are classified as Level 3. We have not elected to apply the fair value option to any of our eligible financial assets and liabilities.

Insurance: We are self-insured for employee healthcare as well as physical damage to automobiles that we own, lease or rent, and product warranty and recall liabilities. In addition, we maintain a deductible/retention program as it relates to insurance for property, inventory, workers’ compensation, automobile liability, asbestos claims, general liability claims (including, among others, certain product liability claims for property damage, death or injury) and cybersecurity claims. These programs have deductibles and self-insured retentions ranging up to $4 million and are secured by various letters of credit totaling $6 million. Our estimated liability and related expenses for claims are based in part upon estimates that insurance carriers, third-party administrators and actuaries provide. We believe that insurance reserves are sufficient to cover outstanding claims, including those incurred but not reported as of the estimation date. Further, we maintain commercially reasonable umbrella/excess policy coverage in excess of the primary limits. We do not have excess coverage for physical damage to automobiles that we own, lease or rent, and product warranty and recall liabilities. Our accrued liabilities related to deductibles/retentions under insurance programs (other than employee healthcare) were $11 million and $7 million as of December 31, 2019 and 2018. In the area of employee healthcare, we have a commercially reasonable excess stop loss protection on a per person per year basis. Reserves for self-insurance accrued liabilities for employee healthcare were $2 million as of December 31, 2019 and 2018.

Income Taxes: We use the liability method for determining our income taxes, under which current and deferred tax assets and liabilities are recorded in accordance with enacted tax laws and rates. Under this method, deferred tax assets and liabilities are recorded for differences between the financial reporting and tax bases of assets and liabilities using the tax rate expected to be in effect when the taxes will actually be paid or refunds received. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in earnings in the period that includes the enactment date. A valuation allowance to reduce deferred tax assets is established when it is more likely than not that some portion or all of the deferred tax assets will not be realized.

In determining the need for valuation allowances and our ability to utilize our deferred tax assets, we consider and make judgments regarding all the available positive and negative evidence, including the timing of the reversal of deferred tax liabilities, estimated future taxable income, ongoing, prudent and feasible tax planning strategies and recent financial results of operations. The amount of valuation allowances, however, could be adjusted in the future if objective negative evidence in the form of cumulative losses is no longer present in certain jurisdictions and additional weight may be given to subjective evidence such as our projections for growth.

Our tax provision is based upon our expected taxable income and statutory rates in effect in each country in which we operate. We are subject to the jurisdiction of numerous domestic and foreign tax authorities, as well as to tax agreements and treaties among these governments. Determination of taxable income in any jurisdiction requires the interpretation of the related tax laws and regulations and the use of estimates and assumptions regarding significant future events such as the amount, timing and character of deductions, permissible revenue recognition methods under the tax law and the sources and character of income and tax credits. Changes in tax laws, regulations, agreements and treaties, foreign currency exchange restrictions or our level of operations or profitability in each taxing jurisdiction could have an impact on the amount of income taxes we provide during any given year.

A tax benefit from an uncertain tax position may be recognized when it is more likely than not that the position will be sustained upon examination, including any related appeals or litigation processes, on the basis of the technical merits. We adjust these liabilities when our judgment changes as a result of the evaluation of new information not previously available. Because of the complexity of some of these uncertainties, the ultimate resolution may result in a payment that is materially different from our current estimate of the tax liabilities. These differences will be reflected as increases or decreases to income tax expense in the period in which the new information is available. We classify interest and penalties related to unrecognized tax positions as income taxes in our financial statements.

Foreign Currency Translation and Transactions: The functional currency of our foreign operations is the applicable local currency. The cumulative effects of translating the balance sheet accounts from the functional currency into the U.S. dollar at current exchange rates are included in accumulated other comprehensive income. The balance sheet accounts (with the exception of stockholders’ equity) are translated using current exchange rates as of the balance sheet date. Stockholders’ equity is translated at historical exchange rates and revenue and expense accounts are translated using a weighted-average exchange rate during the year. Gains or losses resulting from foreign currency transactions are recognized in the consolidated statements of operations.

Equity-Based Compensation: Our equity-based compensation consisted and consists of restricted stock, restricted unit awards, performance share unit awards and nonqualified stock options. The cost of employee services received in exchange for an award of an equity instrument is measured based on the grant-date fair value of the award. Our policy is to expense equity-based compensation using the fair-value of awards granted, modified or settled. Restricted units and restricted stock are credited to equity as they are expensed over their vesting periods based on the grant date value of the shares vested. The fair value of nonqualified stock options is measured on the grant date of the related equity instrument using the Black-Scholes option-pricing model. A Monte Carlo simulation is completed to estimate the fair value of performance share unit awards with a stock price performance component. We expense the fair value of all equity grants, including performance share unit awards, on a straight-line basis over the vesting period.

Revenue Recognition: Revenue is recognized when control of promised goods or services is transferred to our customers in an amount that reflects the consideration to which we expect to be entitled in exchange for those goods or services. Substantially all of our revenue is recognized when products are shipped or delivered to our customers, and payment is due from our customers at the time of billing with a majority of our customers having 30-day terms. Returns are estimated and recorded as a reduction of revenue. Amounts received in advance of shipment are deferred and recognized when the performance obligations are satisfied. Sales taxes collected from customers and remitted to governmental authorities are accounted for on a net basis and, therefore, are excluded from sales in the accompanying consolidated statements of operations. In some cases, particularly with third party pipe shipments, shipping and handling costs are considered separate performance obligations, and as such, the revenue and cost of sales are recorded when the performance obligation is fulfilled. Our contracts with customers ordinarily involve performance obligations that are one year or less. Therefore, we have applied the optional exemption that permits the omission of information about our unfulfilled performance obligations as of the balance sheet dates.

Cost of Sales: Cost of sales includes the cost of inventory sold and related items, such as vendor rebates, inventory allowances and reserves, and shipping and handling costs associated with inbound and outbound freight, as well as depreciation and amortization and amortization of intangible assets. Certain purchasing costs and warehousing activities (including receiving, inspection and stocking costs), as well as general warehousing expenses, are included in selling, general and administrative expenses and not in cost of sales. As such, our gross profit may not be comparable to others that may include these expenses as a component of cost of sales.

Earnings per Share: Basic earnings per share are computed based on the weighted-average number of common shares outstanding, excluding any dilutive effects of unexercised stock options, unvested restricted stock awards, unvested restricted stock unit awards, unvested performance share unit awards, and shares of preferred stock. Diluted earnings per share are computed based on the weighted-average number of common shares outstanding including any dilutive effect of unexercised stock options, unvested restricted stock awards, unvested restricted stock unit awards, unvested performance share unit awards, and shares of preferred stock. The dilutive effect of unexercised stock options is calculated under the treasury stock method. Equity awards and shares of preferred stock are disregarded in the calculations of diluted earnings per share if they are determined to be anti-dilutive.

Concentration of Credit Risk: Most of our business activity is with customers in the energy sector. In the normal course of business, we grant credit to these customers in the form of trade accounts receivable. These receivables could potentially subject us to concentrations of credit risk; however, we minimize this risk by closely monitoring extensions of trade credit. We generally do not require collateral on trade receivables. We have a broad customer base doing business in many regions of the world. During 2019, 2018 and 2017, we did not have sales to any one customer in excess of 10% of sales. At those respective year-ends, no individual customer balances exceeded 10% of accounts receivable.

We have a broad supplier base, sourcing our products in most regions of the world. During 2019, 2018 and 2017, we did not have purchases from any one vendor in excess of 10% of our inventory purchases. At those respective year-ends no individual vendor balance exceeded 10% of accounts payable.

We maintain the majority of our cash and cash equivalents with several financial institutions. These financial institutions are located in many different geographical regions with varying economic characteristics and risks. Deposits held with banks may exceed insurance limits. We believe the risk of loss associated with our cash equivalents to be remote.

Adoption of New Accounting Standards: On January 1, 2019, we adopted ASU 2016-02, Leases, which requires the recognition of lease assets and lease liabilities for those leases classified as operating leases under previous guidance in Accounting Standards Codification 840. We adopted ASU 2016-02 using the modified retrospective approach. The guidance for this approach included an option to not restate comparative periods in transition and elect to use the effective date as the initial application of transition, which we elected. In addition, we elected the package of practical expedients permitted under the transition guidance within the new standard, which among other things, allowed us to carry forward the historical lease classifications. On January 1, 2019, we recorded an operating lease asset of $192 million and an operating lease liability of $208 million. The standard did not impact our consolidated net earnings or cash flows. Adoption of the new standard is more fully described in Note 7.

Recently Issued Accounting Standards: In June 2016, the Financial Accounting Standards Board (“FASB”) issued ASU 2016-13, Measurement of Credit Losses on Financial Instruments, which requires that an entity measure impairment of certain financial instruments, including trade receivables, based on expected losses rather than incurred losses. This update is effective for annual and interim financial statement periods beginning after December 15, 2019, with early adoption permitted for financial statement periods beginning after December 15, 2018. In November 2018, the FASB issued ASU 2018-19 which clarifies guidance in ASU 2016-13. We do not expect the adoption of this standard to materially impact our consolidated financial statements.

In December 2019, the FASB issued ASU 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes, an update intended to simplify various aspects related to accounting for income taxes. This guidance removes certain exceptions to the general principles in Topic 740 and clarifies and amends existing guidance to improve consistent application. This accounting standards update will be effective for annual and interim financial statement periods beginning after December 15, 2020, with early adoption permitted. We are currently evaluating the impact of this accounting standards update, but do not expect the adoption to materially impact our consolidated financial statements.

Revenue Recognition [Abstract]

Revenue Recognition

NOTE 2—REVENUE RECOGNITION

Contract Balances: Variations in the timing of revenue recognition, invoicing and receipt of payment result in categories of assets and liabilities that include invoiced accounts receivable, uninvoiced accounts receivable, contract assets and deferred revenue (contract liabilities) on the consolidated balance sheets.

Generally, revenue recognition and invoicing occur simultaneously as we transfer control of promised goods or services to our customers. We consider contract assets to be accounts receivable when we have an unconditional right to consideration and only the passage of time is required before payment is due. In certain cases, particularly those involving customer-specific documentation requirements, invoicing is delayed until we are able to meet the documentation requirements. In these cases, we recognize a contract asset separate from accounts receivable until those requirements are met, and we are able to invoice the customer. Our contract asset balance associated with these requirements, as of December 31, 2019 and December 31, 2018, was $26 million and $38 million, respectively. These contract asset balances are included within accounts receivable in the accompanying consolidated balance sheets.

We record contract liabilities, or deferred revenue, when cash payments are received from customers in advance of our performance, including amounts which are refundable. The deferred revenue balance at December 31, 2019 and December 31, 2018 was $4 million and $6 million, respectively. During the year ended December 31, 2019, we recognized all of the revenue that was deferred as of December 31, 2018. Deferred revenue balances are included within accrued expenses and other current liabilities in the accompanying consolidated balance sheets.

Disaggregated Revenue: Our disaggregated revenue represents our business of selling PVF and other infrastructure products to the energy sector across each of the upstream (exploration, production and extraction of underground oil and gas), midstream (gathering and transmission of oil and gas, gas utilities, and the storage and distribution of oil and gas) and downstream (crude oil refining and petrochemical and chemical processing and general industrials) markets in each of our reportable segments. Each of our end markets and geographical reportable segments are impacted and influenced by varying factors, including macroeconomic environment, commodity prices, maintenance and capital spending, and exploration and production activity. As such, we believe that this information is important in depicting the nature, amount, timing and uncertainty of our contracts with customers.

The following table presents our revenue disaggregated by revenue source (in millions):

Less: Other inventory reserves		(35)		(40)
	$	701	$	797

Our inventory quantities were reduced during 2019, resulting in a liquidation of a last-in, first out (“LIFO”) inventory layer that was carried at a lower cost prevailing from a prior year, as compared with current costs in the current year (a “LIFO decrement”). A LIFO decrement results in the erosion of layers created in earlier years, and, therefore, a LIFO layer is not created for years that have decrements. For the years ended December 31, 2019, the effect of this LIFO decreased cost of sales by $5 million. There was no LIFO decrement for the years ended December 31, 2018 and 2017.

In the fourth quarter of 2019, we incurred an inventory charge of $5 million associated with excess and obsolete inventory in our International segment. This charge reflected adjustments necessary to reduce the carrying value of these products to their net realizable value.

Leases [Abstract]

Leases

NOTE 7 – LEASES

We lease certain distribution centers, warehouses, office space, land and equipment. Substantially all of these leases are classified as operating leases. We recognize lease expense on a straight-line basis over the lease term. Leases with an initial term of 12 months or less are not recorded on the balance sheet.

Many of our facility leases include one or more options to renew, with renewal terms that can extend the lease term from one year to 15 years with a maximum lease term of 30 years, including renewals. The exercise of lease renewal options is at our sole discretion; therefore, renewals to extend the terms of most leases are not included in our right of use (“ROU”) assets and lease liabilities as they are not reasonably certain of exercise. In the case of our regional distribution centers and certain corporate offices, where the renewal is reasonably certain of exercise, we include the renewal period in our lease term. Leases with escalation adjustments based on an index, such as the consumer price index, are expensed based on current rates. Leases with specified escalation steps are expensed based on the total lease obligation ratably over the life of the lease. The depreciable life of assets and leasehold improvements are limited by the expected lease term. Non-lease components, such as payment of real estate taxes, maintenance, insurance and other operating expenses, have been excluded from the determination of our lease liability.

As most of our leases do not provide an implicit rate, we use an incremental borrowing rate based on the information available at the commencement date in determining the present value of the lease payments using a portfolio approach. For leases that commenced prior to the transition date, we used the incremental borrowing rates as of the beginning of the period of adoption, or January 1, 2019.

Our lease agreements do not contain any material residual value guarantees or material restrictive covenants.

Expense associated with our operating leases was $42 million for the year ended December 31, 2019, which is classified in selling, general and administrative expenses. Cash paid for leases recognized as liabilities was $46 million for the year ended December 31, 2019.

Senior Secured Term Loan B: In May 2018, we entered into Refinancing Amendment No. 2 relating to the Term Loan Credit Agreement, dated as of November 9, 2012, by and among the Company, MRC Global (US) Inc., as the borrower, the other subsidiaries of the Company from time to time party thereto as guarantors, the several lenders from time to time party thereto, Bank of America, N.A., as administrative agent, and U.S. Bank National Association, as collateral trustee. Pursuant to the amendment, the parties agreed to appoint JPMorgan Chase Bank, N.A. as the new administrative agent for the lenders. As amended, the Term Loan Agreement provides for a $400 million seven year Term Loan B (the “Term Loan”), which matures September 22, 2024. Pursuant to this amendment, the Company and the other parties thereto agreed to reduce the interest rate margin applicable to term loans, in the case of loans incurring interest based on the base rate, from 250 basis points to 200 basis points, and in the case of loans incurring interest based on LIBOR, from 350 basis points to 300 basis points. The parties to the amendment also agreed to reduce the base rate ‘floor’ from 2.00% to 1.00% and to reduce the LIBOR ‘floor’ from 1.00% to 0.00%. The parties also reset the prepayment premium applicable to voluntary prepayments of the term loans such that repayments made in connection with certain re-pricing transactions will be subject to a 1% premium if made during the first six months following the date of the amendment. Except as described above, the terms of the Term Loan Agreement generally were not modified as a result of the amendment.

Accordion. The Term Loan allows for incremental increases up to an aggregate of $200 million, plus an additional amount such that the Company’s first lien leverage ratio (the ratio of the Company’s Consolidated EBITDA (as defined under the Term Loan Agreement) to senior secured debt), net of up to $75 million of unrestricted cash, would not exceed 4.00 to 1.00.

Maturity. The scheduled maturity date of the Term Loan is September 22, 2024. The Term Loan will amortize in equal quarterly installments at 1% a year with the payment of the balance at maturity.

Guarantees. The Company and all of the U.S. borrower’s current and future wholly owned material U.S. subsidiaries guaranteed the Term Loan subject to certain exceptions.

Security. The Term Loan is secured by a first lien on all of the Company’s assets and the assets of its domestic subsidiaries, subject to certain exceptions and other than the collateral securing the Global ABL Facility (which includes accounts receivable, inventory and related assets, collectively, the “ABL collateral”), and by a second lien on the ABL collateral. In addition, a pledge secures the Term Loan of all the capital stock of the Company’s domestic subsidiaries and 65% of the capital stock of its first tier foreign subsidiaries, subject to certain exceptions.

Interest Rates and Fees. The Company has the option to pay interest at a base rate, subject to a floor of 1.00%, plus an applicable margin, or at a rate based on LIBOR, subject to a floor of 0.00%, plus an applicable margin. The applicable margin for base rate loans is 200 basis points, and the applicable margin for LIBOR loans is 300 basis points.

Mandatory Prepayment. The Company is required to repay the Term Loan with certain asset sale, insurance and debt proceeds. In addition, on an annual basis, the Company is required to repay an amount equal to 50% of excess cash flow, as defined in the Term Loan agreement, reducing to 25% if the Company’s senior secured leverage ratio is no more than 2.75 to 1.00. No payment of excess cash flow is required if the Company’s senior secured leverage ratio is less than or equal to 2.50 to 1.00.

Restrictive Covenants. The Term Loan does not include any financial maintenance covenants.

The Term Loan contains restrictive covenants (in each case, subject to exclusions) that limit, among other things, the ability of the Company and its restricted subsidiaries to:

make investments, including acquisitions;

prepay certain indebtedness;

grant liens;

incur additional indebtedness;

sell assets;

make fundamental changes to our business;

enter into transactions with affiliates; and

pay dividends.

The Term Loan also contains other customary restrictive covenants. The covenants are subject to various baskets and materiality thresholds, with certain of the baskets permitted by the restrictions on the repayment of subordinated indebtedness, restricted payments and investments being available only when the senior secured leverage ratio of the Company and its restricted subsidiaries is less than 3.75 to 1.00.

The Term Loan provides that the Company and its restricted subsidiaries may incur any first lien indebtedness that is pari passu to the Term Loan so long as the pro forma senior secured leverage ratio of the Company and its restricted subsidiaries is less than or equal to 4.00 to 1.00. The Company and its restricted subsidiaries may incur any second lien indebtedness so long as the pro forma junior secured leverage ratio of the Company and its restricted subsidiaries is less than or equal to 4.75 to 1.00. The Company and its restricted subsidiaries may incur any unsecured indebtedness so long as the total leverage ratio of the Company and its restricted subsidiaries is less than or equal to 5.00 to1.00 or the pro forma consolidated interest coverage ratio of the Company and its restricted subsidiaries is greater than or equal to 2.00 to 1.00. Additionally, under the Term Loan, the Company and its restricted subsidiaries may incur indebtedness under the Global ABL Facility (or any replacement facility) in an amount not to exceed the greater of $1.3 billion and a borrowing base (equal to, subject to certain exceptions, 85% of all accounts receivable and 65% of the book value of all inventory owned by the Company and its restricted subsidiaries).

The Term Loan contains certain customary representations and warranties, affirmative covenants and events of default, including, among other things, payment defaults, breaches of representations and warranties, covenant defaults, cross-defaults to certain indebtedness, certain events of bankruptcy, certain events under ERISA, judgment defaults, actual or asserted failure of any material guaranty or security documents supporting the Term Loan to be in full force and effect and change of control. If such an event of default occurs, the Agent under the Term Loan is entitled to take various actions, including the acceleration of amounts due under the Term Loan and all other actions that a secured creditor is permitted to take following a default.

Global ABL Credit Facility: : In September 2017, the Company entered into a Third Amended and Restated Loan, Security and Guarantee Agreement (the “Global ABL Facility”) by and among the Company, the subsidiaries of the Company from time to time party thereto as borrowers and guarantors, the several lenders from time to time party thereto and Bank of America, N.A. as administrative agent, security trustee and collateral agent. As part of the amendment, the multi-currency global asset-based revolving credit facility was re-sized to $800 million from $1.05 billion and the maturity was extended to September 2022 from July 2019. This facility is comprised of $675 million in revolver commitments in the United States, $65 million in Canada, $18 million in Norway, $15 million in Australia, $13 million in the Netherlands, $7 million in the United Kingdom and $7 million in Belgium. It contains an accordion feature that allows us to increase the principal amount of the facility by up to $200 million, subject to securing additional lender commitments.

Guarantees. Each of our current and future wholly owned material U.S. subsidiaries and MRC Global Inc. guarantees the obligations of our borrower subsidiaries under the Global ABL Facility. Additionally, each of our non-U.S. borrower subsidiaries guarantees the obligations of our other non-U.S. borrower subsidiaries under the Global ABL Facility. No non-U.S. subsidiary guarantees the U.S. tranche, and no property of our non-U.S. subsidiaries secures the U.S. tranche.

Security. Obligations under the U.S. tranche are primarily secured, subject to certain exceptions, by a first-priority security interest in the accounts receivable, inventory and related assets of our wholly owned, material U.S. subsidiaries. The security interest in accounts receivable, inventory and related assets of the U.S. borrower subsidiaries ranks prior to the security interest in this collateral which secures the Term Loan. The obligations of any of our non-U.S. borrower subsidiaries are primarily secured, subject to certain exceptions, by a first-priority security interest in the accounts receivable, inventory and related assets of the non-U.S. subsidiary and our wholly owned material U.S. subsidiaries.

Borrowing Bases. Each of our non-U.S. borrower subsidiaries has a separate standalone borrowing base that limits the non-U.S. subsidiary’s ability to borrow under its respective tranche, provided that the non-U.S. subsidiaries may utilize excess availability under the U.S. tranche to borrow amounts in excess of their respective borrowing bases (but not to exceed the applicable commitment amount for the foreign subsidiary’s jurisdiction), which utilization will reduce availability under the U.S. tranche dollar for dollar.

Subject to the foregoing, our ability to borrow in each jurisdiction, other than Belgium, under the Global ABL Facility is limited by a borrowing base in that jurisdiction equal to 85% of eligible receivables, plus the lesser of 70% of eligible inventory and 85% of appraised net orderly liquidation value of the inventory. In Belgium, our borrowing is limited by a borrowing base determined under Belgian law.

Interest Rates. U.S. borrowings under the facility bear interest at LIBOR plus a margin varying between 1.25% and 1.75% based on our fixed charge coverage ratio. Canadian borrowings under the facility bear interest at the Canadian Dollar Bankers’ Acceptances Rate (“BA Rate”) plus a margin varying between 1.25% and 1.75% based on our fixed charge coverage ratio. Borrowings by our foreign borrower subsidiaries bear interest at a benchmark rate, which varies based on the currency in which such borrowings are made, plus a margin varying between 1.25% and 1.75% based on our fixed charge coverage ratio.

Excess Availability. At December 31, 2019, availability under our revolving credit facilities was $451 million.

Interest on Borrowings: The interest rates on our borrowings outstanding at December 31, 2019 and 2018, including a floating to fixed interest rate swap and amortization of debt issuance costs, were as follows:


	December 31,
	2019	2018

We record a valuation allowance when it is more likely than not that some portion or all of our deferred tax assets will not be realized. The ultimate realization of the deferred tax assets depends on the ability to generate sufficient taxable income of the appropriate character in the future and in the appropriate taxing jurisdictions. If we were to determine that we would be able to realize our deferred tax assets in the future in excess of their net recorded amount, we would make an adjustment to the valuation allowance, which would reduce the provision for income taxes.

In the United States, we had approximately $18 million of state net operating loss (“NOL”) carryforwards as of December 31, 2019, which will expire in future years through 2032 and foreign tax credit (“FTC”) carryforwards of $5 million, which will expire in future years through 2027. In certain non-U.S. jurisdictions, we had $189 million of NOL carryforwards, of which $166 million have no expiration and $23 million will expire in future years through 2027. We believe that it is more likely than not that the benefit from U.S. state NOL and FTC carryforwards and non-U.S. jurisdiction NOL carryforwards will not be realized. As such, we have recorded full valuation allowance on the deferred tax assets related to these NOL and FTC carryforwards.

On December 22, 2017, the Tax Cuts and Jobs Act of 2017 (the “Tax Act”) was enacted. Among the significant changes to the U.S. Internal Revenue Code, the Tax Act reduced the U.S. federal corporate income tax rate from 35% to 21% effective January 1, 2018 and created a new dividend-exemption territorial system with a one-time transition tax on foreign earnings which were previously not taxed in the U.S. We applied the guidance in Staff Accounting Bulletin (“SAB”) 118 when accounting for the enactment-date effects of the Tax Act in 2017 and throughout 2018. As of December 31, 2017, we remeasured our U.S. deferred tax assets and liabilities based on the rates at which they were expected to reverse in the future (which was generally 21%) and recorded a provisional tax benefit of $57 million. Upon further analysis of certain aspects of the Tax Act and refinement of our calculations in 2018, we reduced our provisional tax benefit amount by $1 million. The one-time transition tax, calculated as of December 31, 2017, is based on the

total post-1986 earnings and profits of our foreign subsidiaries. We recorded a provisional expense of $7 million for the one-time transition tax liability during 2017. Upon further analyses of the Tax Act and notices and regulations issued and proposed by the U.S. Department of the Treasury and the Internal Revenue Service, we finalized our calculations of the transition tax liability during 2018 and decreased our provisional expense by $4 million. As of December 31, 2019, our transition tax liability had been paid.

The pre-2018 earnings of our foreign subsidiaries were taxed as part of the transition tax described above. Dividends from the earnings of our foreign subsidiaries subsequent to 2017 are eligible for a 100% dividend exclusion in determining our U.S. federal taxes. As such, we do not expect future dividends, if any, from the earnings of our foreign subsidiaries to result in U.S. federal income taxes. Deferred tax liabilities arising from the difference between the financial reporting and income tax bases inherent in these foreign subsidiaries, referred to as outside basis differences, have not been provided for U.S. income tax purposes because we do not intend to sell, liquidate or otherwise trigger the recognition of U.S. taxable income with regard to our investment in these foreign subsidiaries. Determining the amount of U.S. deferred tax liabilities associated with outside basis differences is not practicable at this time.

Our tax filings for various periods are subject to audit by the tax authorities in most jurisdictions where we conduct business. We are no longer subject to U.S. federal income tax examination for all years through 2015 and the statute of limitations at our international locations is generally six years or seven years.

At December 31, 2019 and 2018, our unrecognized tax benefits totaled $4 million and $5 million, respectively, of which it is reasonably possible that $2 million could be settled during the next twelve month period as a result of the conclusion of a state audit.

Redeemable Preferred Stock

NOTE 11—REDEEMABLE PREFERRED STOCK

Preferred Stock Issuance

In June 2015, we issued 363,000 shares of Series A Convertible Perpetual Preferred Stock (the “Preferred Stock”) and received gross proceeds of $363 million. The Preferred Stock ranks senior to our common stock with respect to dividend rights and rights on liquidation, winding-up and dissolution. The Preferred Stock has a stated value of $1,000 per share, and holders of Preferred Stock are entitled to cumulative dividends payable quarterly in cash at a rate of 6.50% per annum. In June 2018, the holders of Preferred Stock designated one member to our Board of Directors. If we fail to declare and pay the quarterly dividend for an amount equal to six or more dividend periods, the holders of the Preferred Stock would be entitled to designate an additional member to our Board of Directors. Holders of Preferred Stock are entitled to vote together with the holders of the common stock as a single class, in each case, on an as-converted basis, except where a separate class vote of the common stockholders is required by law. Holders of Preferred Stock have certain limited special approval rights, including with respect to the issuance of pari passu or senior equity securities of the Company.

The Preferred Stock is convertible at the option of the holders into shares of common stock at an initial conversion rate of 55.9284 shares of common stock for each share of Preferred Stock, which represents an initial conversion price of $17.88 per share of common stock, subject to adjustment. On or after June 10, 2020, the Company will have the option to redeem, in whole but not in part, all the outstanding shares of Preferred Stock at 105% of par value, subject to certain redemption price adjustments. On or after June 10, 2022, the Company will have the option to redeem, in whole but not in part, all of the outstanding shares of Preferred Stock at par value, subject to certain redemption price adjustments. We may elect to convert the Preferred Stock, in whole but not in part, into the relevant number of shares of common stock if the last reported sale price of the common stock has been at least 150% of the conversion price then in effect for a specified period. The conversion rate is subject to customary anti-dilution and other adjustments.

Holders of the Preferred Stock may, at their option, require the Company to repurchase their shares in the event of a fundamental change, as defined in the agreement. The repurchase price is based on the original $1,000 per share purchase price except in the case of a liquidation in which case they would receive the greater of $1,000 per share and the amount that would be received if they held common stock converted at the conversion rate in effect at the time of the fundamental change. Because this feature could require redemption as a result of the occurrence of an event not solely within the control of the Company, the Preferred Stock is classified as temporary equity on our balance sheet.

Employee Benefit Plans

NOTE 13—EMPLOYEE BENEFIT PLANS

Equity Compensation Plans: Our 2007 Stock Option Plan (prior to its replacement) permitted the grant of stock options to our employees, directors and consultants for up to 3,750,000 shares of common stock. The options were not to be granted with an exercise price less than the fair market value of the Company’s common stock on the date of the grant, nor for a term exceeding ten years. Vesting generally occurred over a five year period on the anniversaries of the date specified in the employees’ respective option agreements, subject to accelerated vesting under certain circumstances set forth in the option agreements. During 2019, 1,104 stock options were exercised, and no stock options were granted under this plan.

In April 2012, we replaced our 2007 Stock Option Plan and our 2007 Restricted Stock Plan with the 2011 Omnibus Incentive Plan. No additional shares or other equity interests will be awarded under the prior plans. The 2011 Omnibus Incentive Plan originally had 3,250,000 shares reserved for issuance pursuant to the plan. In both April 2015 and 2019, our shareholders approved an additional 4,250,000 shares and 2,500,000 shares, respectively, for reservation for issuance under the plan. The plan permits the issuance of stock options, stock appreciation rights, restricted stock, restricted stock units, performance shares, performance units and other stock-based and cash-based awards. Since the adoption of the 2011 Omnibus Incentive Plan, the Company’s Board of Directors has periodically granted stock options, restricted stock awards, restricted stock units and performance share units to directors and employees, but no other types of awards have been granted under the plan. Options and stock appreciation rights may not be granted at prices less than their fair market value on the date of the grant, nor for a term exceeding ten years. For employees, vesting generally occurs over a three year to five year period on the anniversaries of the date specified in the employees’ respective agreements, subject to accelerated vesting under certain circumstances set forth in the agreements. Vesting for directors generally occurs on the one year anniversary of the grant date. In 2019, 74,055 shares of restricted stock, 242,290 performance share units and 712,600 restricted units were granted to executive management, members of our Board of Directors and employees under this plan. During 2018, 81,542 shares of restricted stock, 222,435 performance share units and 507,507 restricted units were granted to executive management, members of our Board of Directors and employees under this plan. To date, 7,711,359 shares have been granted under this plan. A Black-Scholes option pricing model is used to estimate the fair value of the stock options. A Monte Carlo simulation is completed to estimate the fair value of performance share unit awards with a stock price performance component. We expense the fair value of all equity grants, including performance share unit awards, on a straight line basis over the vesting period.

Performance share units have been granted to certain executive officers. The performance unit awards will be earned only to the extent that MRC Global attains specified performance goals over a three year period relating to MRC Global’s total shareholder return compared to companies within the Philadelphia Oil Service Index and specified return on average net capital employed calculation (“RANCE”) goals established on the date in which the award was granted. The number of shares awarded at the end of the three year period could vary from zero, if performance goals are not met, to as much as 200% of target, if performance goals are exceeded.

NOTE 15—SEGMENT, GEOGRAPHIC AND PRODUCT LINE INFORMATION

In 2019, as a result of changes in our management structure, we combined our U.S. Eastern Region and Gulf Coast and our U.S. Western region into one operating segment. Previously, the two separate U.S. operating segments were combined for reporting purposes as a result of their economic similarity. Following this change, our business is comprised of three operating and reportable segments: U.S., Canada and International. Our International segment consists of our operations outside of the U.S. and Canada. These segments represent our business of selling PVF and other infrastructure products and services to the energy sector across each of the upstream (exploration, production and extraction of underground oil and gas), midstream (gathering and transmission of oil and gas, gas utilities, and the storage and distribution of oil and gas) and downstream (crude oil refining, petrochemical and chemical processing and general industrials) markets.

Fair Value Measurements

NOTE 16—FAIR VALUE MEASUREMENTS

With the exception of long-term debt, the fair values of our financial instruments, including cash and cash equivalents, accounts receivable, trade accounts payable and accrued liabilities approximate carrying value. The carrying value of our debt was $551 million and $684 million at December 31, 2019 and 2018, respectively. The fair value of our debt was $554 million and $675 million at December 31, 2019 and 2018, respectively. The carrying values of amounts outstanding under our Global ABL Facility approximate fair value. We estimate the fair value of the Term Loan using Level 2 inputs, or quoted market prices as of December 31, 2019 and 2018, respectively.

Goodwill and other intangible assets are subject to annual impairment testing, which requires a significant degree of management judgment. If the testing results in impairment, we would measure goodwill and other intangible assets using level 3 non-recurring inputs.

Commitments and Contingencies

NOTE 17—COMMITMENTS AND CONTINGENCIES

Legal Proceedings

Asbestos Claims. We are one of many defendants in lawsuits that plaintiffs have brought seeking damages for personal injuries that exposure to asbestos allegedly caused. Plaintiffs and their family members have brought these lawsuits against a large volume of defendant entities as a result of the various defendants’ manufacture, distribution, supply or other involvement with asbestos, asbestos-containing products or equipment or activities that allegedly caused plaintiffs to be exposed to asbestos. These plaintiffs typically assert exposure to asbestos as a consequence of third-party manufactured products that the Company’s subsidiary, MRC Global (US) Inc., purportedly distributed. As of December 31, 2019, we are a named defendant in approximately 597 lawsuits involving approximately 1,173 claims. No asbestos lawsuit has resulted in a judgment against us to date, with the majority being settled, dismissed or otherwise resolved. Applicable third-party insurance has substantially covered these claims, and insurance should continue to cover a substantial majority of existing and anticipated future claims. Accordingly, we have recorded a liability for our estimate of the most likely settlement of asserted claims and a related receivable from insurers for our estimated recovery, to the extent we believe that the amounts of recovery are probable.

We annually conduct analyses of our asbestos-related litigation to estimate the adequacy of the reserve for pending and probable asbestos-related claims. Given these estimated reserves and existing insurance coverage that has been available to cover substantial portions of these claims, we believe that our current accruals and associated estimates relating to pending and probable asbestos-related litigation likely to be asserted over the next 15 years are currently adequate. This belief, however, relies on a number of assumptions, including:

That our future settlement payments, disease mix and dismissal rates will be materially consistent with historic experience;

That future incidences of asbestos-related diseases in the U.S. will be materially consistent with current public health estimates;

That the rates at which future asbestos-related mesothelioma incidences result in compensable claims filings against us will be materially consistent with its historic experience;

That insurance recoveries for settlement payments and defense costs will be materially consistent with historic experience;

That legal standards (and the interpretation of these standards) applicable to asbestos litigation will not change in material respects;

That there are no materially negative developments in the claims pending against us; and

That key co-defendants in current and future claims remain solvent.

If any of these assumptions prove to be materially different in light of future developments, liabilities related to asbestos-related litigation may be materially different than amounts accrued or estimated. Further, while we anticipate that additional claims will be filed in the future, we are unable to predict with any certainty the number, timing and magnitude of such future claims. In addition, applicable insurance policies are subject to overall caps on limits, which coverage may exhaust the amount available from insurers under those limits. In those cases, the Company would seek indemnity payments from excess insurance policies, but the insurers that issued those policies may not be solvent or may not make payments under the policies without contesting their liability. In our opinion, there are no pending legal proceedings that are likely to have a material adverse effect on our consolidated financial statements.

Other Legal Claims and Proceedings. From time to time, we have been subject to various claims and involved in legal proceedings incidental to the nature of our businesses. We maintain insurance coverage to reduce financial risk associated with certain of these claims and proceedings. It is not possible to predict the outcome of these claims and proceedings. However, in our opinion, there are no pending legal proceedings that are likely to have a material adverse effect on our consolidated financial statements.

Product Claims. From time to time, in the ordinary course of our business, our customers may claim that the products we distribute are either defective or require repair or replacement under warranties that either we or the manufacturer may provide to the customer. These proceedings are, in the opinion of management, ordinary and routine matters incidental to our normal business. Our purchase orders with our suppliers generally require the manufacturer to indemnify us against any product liability claims, leaving the manufacturer ultimately responsible for these claims, although we did incur a charge of $5 million related to the doubtful collection of a product claim against a foreign supplier in the year ended December 31, 2019. In many cases, state, provincial or foreign law provides protection to distributors for these sorts of claims, shifting the responsibility to the manufacturer. In some cases, we could be required to repair or replace the products for the benefit of our customer and seek our recovery from the manufacturer for our expense. In our opinion, the likelihood that the ultimate disposition of any of these claims and legal proceedings would have a material adverse effect on our consolidated financial statements is remote.

Customer Contracts

We have contracts and agreements with many of our customers that dictate certain terms of our sales arrangements (pricing, deliverables, etc.). While we make every effort to abide by the terms of these contracts, certain provisions are complex and may be subject to varying interpretations. Under the terms of these contracts, our customers have the right to audit our adherence to the contract terms. Historically, any settlements that have resulted from these customer audits have been immaterial to our consolidated financial statements.

Letters of Credit

Our letters of credit outstanding at December 31, 2019 approximated $33 million.

Bank Guarantees

Certain of our international subsidiaries have trade guarantees that banks have issued on their behalf. The amount of these guarantees at December 31, 2019 was approximately $6 million.

Purchase Commitments

We have purchase obligations consisting primarily of inventory purchases made in the normal course of business to meet operating needs. While our vendors often allow us to cancel these purchase orders without penalty, in certain cases, cancellations may subject us to cancellation fees or penalties depending on the terms of the contract.

Warranty Claims

We are involved from time to time in various warranty claims, which arise in the ordinary course of business. Historically, any settlements that have resulted from these warranty claims have been immaterial to our consolidated financial statements.

Significant Accounting Policies (Policy)	12 Months Ended
Significant Accounting Policies (Policy)	Dec. 31, 2019
Significant Accounting Policies [Abstract]
Business Operations	Business Operations: MRC Global Inc. is a holding company headquartered in Houston, Texas. Our wholly owned subsidiaries are global distributors of pipe, valves, fittings (“PVF”) and other infrastructure products and services across each of the upstream (exploration, production and extraction of underground oil and gas), midstream (gathering and transmission of oil and gas, gas utilities, and the storage and distribution of oil and gas) and downstream (crude oil refining and petrochemical processing) sectors. We have branches in principal industrial, hydrocarbon producing and refining areas throughout the United States, Canada, Europe, Asia, Australasia, the Middle East and Caspian. Our products are obtained from a broad range of suppliers.
Basis of Presentation	Basis of Presentation: The accompanying consolidated financial statements include the accounts of MRC Global Inc. and its wholly owned and majority owned subsidiaries (collectively referred to as the “Company” or by such terms as “we,” “our” or “us”). All material intercompany balances and transactions have been eliminated in consolidation.
Use of Estimates	Use of Estimates: The preparation of financial statements in conformity with the accounting principles generally accepted in the United States of America requires us to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenue and expenses during the reported period. We believe that our most significant estimates and assumptions are related to estimated losses on accounts receivable, the last-in, first-out (“LIFO”) inventory costing methodology, estimated net realizable value on excess and obsolete inventories, goodwill, intangible assets, deferred taxes and self-insurance programs. Actual results could differ materially from those estimates.
Cash Equivalents	Cash Equivalents: We consider all highly liquid investments with maturities of three months or less at the date of purchase to be cash equivalents.
Allowance for Doubtful Accounts	Allowance for Doubtful Accounts: We evaluate the adequacy of the allowance for losses on receivables based upon periodic evaluation of accounts that may have a higher credit risk using information available about the customer and other relevant data. This formal analysis is inherently subjective and requires us to make significant estimates of factors affecting doubtful accounts including customer specific information, current economic conditions, volume, growth and composition of the account, and other factors such as financial statements, news reports and published credit ratings. The amount of the allowance for the remainder of the trade balance is not evaluated individually but is based upon historical loss experience. Because this process is subjective and based on estimates, ultimate losses may differ from those estimates. Receivable balances are written off when we determine that the balance is uncollectible. Subsequent recoveries, if any, are credited to the allowance when received. The provision for losses on receivables is included in selling, general and administrative expenses in the accompanying consolidated statements of operations.
Inventories	Inventories: Our inventories are valued at the lower of cost, principally LIFO, or market. We believe that the use of LIFO results in a better matching of costs and revenue. This practice excludes certain inventories, which are held outside of the United States, approximating $181 million and $187 million at December 31, 2019 and 2018, respectively, which are valued at the lower of weighted-average cost or net realizable value. Our inventory is substantially comprised of finished goods. Reserves for excess and obsolete inventories are determined based on analyses comparing inventories on hand to sales activity over time. The reserve, which totaled $35 million and $40 million at December 31, 2019 and 2018, respectively, is the amount deemed necessary to reduce the cost of the inventory to its estimated net realizable value.
Debt Issuance Costs	Debt Issuance Costs: We defer costs directly related to obtaining financing and amortize them over the term of the indebtedness on a straight-line basis. The use of the straight-line method does not produce results that are materially different from those which would result from the use of the effective interest method. These amounts are reflected in the consolidated statement of operations as a component of interest expense. Debt issuance costs associated with our Global ABL Facility are presented in other assets and totaled $2 million and $3 million at December 31, 2019 and 2018, respectively. Debt issuance costs associated with our Term Loan are presented as a reduction of the carrying amount of the debt liability and totaled $2 million at December 31, 2019 and 2018.
Property, Plant and Equipment	Property, Plant and Equipment: Land, buildings and equipment are stated on the basis of cost. For financial statement purposes, depreciation is computed over the estimated useful lives of such assets principally by the straight-line method; accelerated depreciation and cost recovery methods are used for income tax purposes. Leasehold improvements are amortized using the straight-line method over the shorter of the remaining lease term or the estimated useful life of the improvements. When assets are retired or otherwise disposed of, the cost and related accumulated depreciation are removed from the accounts and any gain or loss is reflected in income for the period. Maintenance and repairs are charged to expense as incurred. Certain systems development costs related to the purchase, development and installation of computer software are capitalized and amortized over the estimated useful life of the related asset. Costs incurred prior to the development stage, as well as maintenance, training costs and general and administrative expenses are expensed as incurred.
Goodwill and Other Intangible Assets	Goodwill and Other Intangible Assets: Goodwill represents the excess of acquisition cost over the fair value of net assets acquired. Goodwill and intangible assets with indefinite useful lives are tested for impairment annually, or more frequently if circumstances indicate that impairment may exist. We evaluate goodwill for impairment at the reporting unit level. Within each reporting unit, we have elected to aggregate the component countries and regions into a single reporting unit based on their similar economic characteristics, products, customers, suppliers, methods of distribution and the manner in which we operate each reporting unit. We perform our annual tests for goodwill impairment as of October 1^st of each year, updating on an interim basis should indications of impairment exist. The goodwill impairment test compares the carrying value of the reporting unit that has the goodwill with the estimated fair value of that reporting unit. To the extent the carrying value of a reporting unit is greater than its estimated fair value, a goodwill impairment charge is recorded for the difference, up to the carrying value of goodwill. Our impairment methodology uses discounted cash flow and multiples of cash earnings valuation techniques, acquisition control premium and valuation comparisons to similar businesses. Each of these methods involves Level 3 unobservable market inputs and require us to make certain assumptions and estimates regarding future operating results, the extent and timing of future cash flows, working capital, sales prices, profitability, discount rates and growth trends. While we believe that such assumptions and estimates are reasonable, the actual results may differ materially from the projected results. Intangible assets with indefinite useful lives are tested for impairment annually or more frequently if circumstances indicate that impairment may exist. This test compares the carrying value of the indefinite-lived intangible assets with their estimated fair value. If the carrying value is more than the estimated fair value, impairment losses are recognized in an amount equal to the excess of the carrying value over the estimated fair value. Our impairment methodology uses discounted cash flow and estimated royalty rate valuation techniques. Each of these methods involves Level 3 unobservable market inputs and requires us to make certain assumptions and estimates regarding future operating results, sales prices, discount rates and growth trends. While we believe that such assumptions and estimates are reasonable, the actual results may differ materially from the projected results. Other intangible assets primarily include trade names, customer bases and noncompetition agreements resulting from business acquisitions. Other intangible assets are recorded at fair value at the date of acquisition. Amortization is provided using the straight-line method over their estimated useful lives, ranging from two years to twenty years. The carrying value of amortizable intangible assets is subject to an impairment test when events or circumstances indicate a possible impairment. When events or circumstances indicate a possible impairment, we assess recoverability from future operations using undiscounted cash flows derived from the lowest appropriate asset group. If the carrying value exceeds the undiscounted cash flows, an impairment charge would be recognized to the extent that the carrying value exceeds the fair value, which is determined based on a discounted cash flow analysis. While we believe that assumptions and estimates utilized in the impairment analysis are reasonable, the actual results may differ materially from the projected results. These impairments are determined prior to performing our goodwill impairment test.
Derivatives and Hedging	Derivatives and Hedging: From time to time, we utilize interest rate swaps to reduce our exposure to potential interest rate increases. We have designated our interest rate swap as an effective cash flow hedge utilizing the guidance under ASU 2017-12. As such, the valuation of the interest rate swap is recorded as an asset or liability, and the gain or loss on the derivative is recorded as a component of other comprehensive income. Interest rate swap agreements are reported on the accompanying balance sheets at fair value utilizing observable Level 2 inputs such as yield curves and other market-based factors. We obtain dealer quotations to value our interest rate swap agreements. The fair value of our interest rate swap is estimated based on the present value of the difference between expected cash flows calculated at the contracted interest rates and the expected cash flows at current market interest rates.We utilize foreign exchange forward contracts (exchange contracts) and options to manage our foreign exchange rate risks resulting from purchase commitments and sales orders. Changes in the fair values of our exchange contracts are based upon independent market quotes. We do not designate our exchange contracts as hedging instruments; therefore, we record our exchange contracts on the consolidated balance sheets at fair value, with the gains and losses recognized in earnings in the period of change.
Fair Value	Fair Value: We measure certain of our assets and liabilities at fair value on a recurring basis. Fair value is an exit price, representing the amount that would be received to sell an asset or be paid to transfer a liability in an orderly transaction between market participants. As such, fair value is a market-based measurement that is determined based on assumptions that market participants would use in pricing an asset or a liability. A three-tier fair value hierarchy is established as a basis for considering such assumptions for inputs used in the valuation methodologies to measuring fair value: Level 1: Quoted prices (unadjusted) in active markets for identical assets or liabilities that the entity has the ability to access at the measurement date. Level 2: Significant observable inputs other than quoted prices included within Level 1 that are observable for the asset or liability, either directly or indirectly, such as quoted prices for similar assets or liabilities, quoted prices in markets that are not active, and other inputs that are observable or can be corroborated by observable market data. Level 3: Significant unobservable inputs for the asset or liability. Unobservable inputs reflect our own assumptions about the assumptions that market participants would use in pricing an asset or liability (including all assumptions about risk). Certain assets and liabilities are measured at fair value on a nonrecurring basis. Our assets and liabilities measured at fair value on a nonrecurring basis include property, plant and equipment, goodwill and other intangible assets. We do not measure these assets at fair value on an ongoing basis; however, these assets are subject to fair value adjustments in certain circumstances, such as when we recognize an impairment. Our impairment methodology for goodwill and other indefinite-lived intangible assets uses both (i) a discounted cash flow analysis requiring certain assumptions and estimates to be made regarding the extent and timing of future cash flows, discount rates and growth trends and (ii) valuation based on our publicly traded common stock. As all of the assumptions employed to measure these assets and liabilities on a nonrecurring basis are based on management’s judgment using internal and external data, these fair value determinations are classified as Level 3. We have not elected to apply the fair value option to any of our eligible financial assets and liabilities.
Insurance	Insurance: We are self-insured for employee healthcare as well as physical damage to automobiles that we own, lease or rent, and product warranty and recall liabilities. In addition, we maintain a deductible/retention program as it relates to insurance for property, inventory, workers’ compensation, automobile liability, asbestos claims, general liability claims (including, among others, certain product liability claims for property damage, death or injury) and cybersecurity claims. These programs have deductibles and self-insured retentions ranging up to $4 million and are secured by various letters of credit totaling $6 million. Our estimated liability and related expenses for claims are based in part upon estimates that insurance carriers, third-party administrators and actuaries provide. We believe that insurance reserves are sufficient to cover outstanding claims, including those incurred but not reported as of the estimation date. Further, we maintain commercially reasonable umbrella/excess policy coverage in excess of the primary limits. We do not have excess coverage for physical damage to automobiles that we own, lease or rent, and product warranty and recall liabilities. Our accrued liabilities related to deductibles/retentions under insurance programs (other than employee healthcare) were $11 million and $7 million as of December 31, 2019 and 2018. In the area of employee healthcare, we have a commercially reasonable excess stop loss protection on a per person per year basis. Reserves for self-insurance accrued liabilities for employee healthcare were $2 million as of December 31, 2019 and 2018.
Income Taxes	Income Taxes: We use the liability method for determining our income taxes, under which current and deferred tax assets and liabilities are recorded in accordance with enacted tax laws and rates. Under this method, deferred tax assets and liabilities are recorded for differences between the financial reporting and tax bases of assets and liabilities using the tax rate expected to be in effect when the taxes will actually be paid or refunds received. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in earnings in the period that includes the enactment date. A valuation allowance to reduce deferred tax assets is established when it is more likely than not that some portion or all of the deferred tax assets will not be realized. In determining the need for valuation allowances and our ability to utilize our deferred tax assets, we consider and make judgments regarding all the available positive and negative evidence, including the timing of the reversal of deferred tax liabilities, estimated future taxable income, ongoing, prudent and feasible tax planning strategies and recent financial results of operations. The amount of valuation allowances, however, could be adjusted in the future if objective negative evidence in the form of cumulative losses is no longer present in certain jurisdictions and additional weight may be given to subjective evidence such as our projections for growth. Our tax provision is based upon our expected taxable income and statutory rates in effect in each country in which we operate. We are subject to the jurisdiction of numerous domestic and foreign tax authorities, as well as to tax agreements and treaties among these governments. Determination of taxable income in any jurisdiction requires the interpretation of the related tax laws and regulations and the use of estimates and assumptions regarding significant future events such as the amount, timing and character of deductions, permissible revenue recognition methods under the tax law and the sources and character of income and tax credits. Changes in tax laws, regulations, agreements and treaties, foreign currency exchange restrictions or our level of operations or profitability in each taxing jurisdiction could have an impact on the amount of income taxes we provide during any given year. A tax benefit from an uncertain tax position may be recognized when it is more likely than not that the position will be sustained upon examination, including any related appeals or litigation processes, on the basis of the technical merits. We adjust these liabilities when our judgment changes as a result of the evaluation of new information not previously available. Because of the complexity of some of these uncertainties, the ultimate resolution may result in a payment that is materially different from our current estimate of the tax liabilities. These differences will be reflected as increases or decreases to income tax expense in the period in which the new information is available. We classify interest and penalties related to unrecognized tax positions as income taxes in our financial statements.
Foreign Currency Translation and Transactions	Foreign Currency Translation and Transactions: The functional currency of our foreign operations is the applicable local currency. The cumulative effects of translating the balance sheet accounts from the functional currency into the U.S. dollar at current exchange rates are included in accumulated other comprehensive income. The balance sheet accounts (with the exception of stockholders’ equity) are translated using current exchange rates as of the balance sheet date. Stockholders’ equity is translated at historical exchange rates and revenue and expense accounts are translated using a weighted-average exchange rate during the year. Gains or losses resulting from foreign currency transactions are recognized in the consolidated statements of operations.
Equity-Based Compensation	Equity-Based Compensation: Our equity-based compensation consisted and consists of restricted stock, restricted unit awards, performance share unit awards and nonqualified stock options. The cost of employee services received in exchange for an award of an equity instrument is measured based on the grant-date fair value of the award. Our policy is to expense equity-based compensation using the fair-value of awards granted, modified or settled. Restricted units and restricted stock are credited to equity as they are expensed over their vesting periods based on the grant date value of the shares vested. The fair value of nonqualified stock options is measured on the grant date of the related equity instrument using the Black-Scholes option-pricing model. A Monte Carlo simulation is completed to estimate the fair value of performance share unit awards with a stock price performance component. We expense the fair value of all equity grants, including performance share unit awards, on a straight-line basis over the vesting period.
Revenue Recognition	Revenue Recognition: Revenue is recognized when control of promised goods or services is transferred to our customers in an amount that reflects the consideration to which we expect to be entitled in exchange for those goods or services. Substantially all of our revenue is recognized when products are shipped or delivered to our customers, and payment is due from our customers at the time of billing with a majority of our customers having 30-day terms. Returns are estimated and recorded as a reduction of revenue. Amounts received in advance of shipment are deferred and recognized when the performance obligations are satisfied. Sales taxes collected from customers and remitted to governmental authorities are accounted for on a net basis and, therefore, are excluded from sales in the accompanying consolidated statements of operations. In some cases, particularly with third party pipe shipments, shipping and handling costs are considered separate performance obligations, and as such, the revenue and cost of sales are recorded when the performance obligation is fulfilled. Our contracts with customers ordinarily involve performance obligations that are one year or less. Therefore, we have applied the optional exemption that permits the omission of information about our unfulfilled performance obligations as of the balance sheet dates.
Cost of Sales	Cost of Sales: Cost of sales includes the cost of inventory sold and related items, such as vendor rebates, inventory allowances and reserves, and shipping and handling costs associated with inbound and outbound freight, as well as depreciation and amortization and amortization of intangible assets. Certain purchasing costs and warehousing activities (including receiving, inspection and stocking costs), as well as general warehousing expenses, are included in selling, general and administrative expenses and not in cost of sales. As such, our gross profit may not be comparable to others that may include these expenses as a component of cost of sales.
Earnings Per Share	Earnings per Share: Basic earnings per share are computed based on the weighted-average number of common shares outstanding, excluding any dilutive effects of unexercised stock options, unvested restricted stock awards, unvested restricted stock unit awards, unvested performance share unit awards, and shares of preferred stock. Diluted earnings per share are computed based on the weighted-average number of common shares outstanding including any dilutive effect of unexercised stock options, unvested restricted stock awards, unvested restricted stock unit awards, unvested performance share unit awards, and shares of preferred stock. The dilutive effect of unexercised stock options is calculated under the treasury stock method. Equity awards and shares of preferred stock are disregarded in the calculations of diluted earnings per share if they are determined to be anti-dilutive.
Concentration of Credit Risk	Concentration of Credit Risk: Most of our business activity is with customers in the energy sector. In the normal course of business, we grant credit to these customers in the form of trade accounts receivable. These receivables could potentially subject us to concentrations of credit risk; however, we minimize this risk by closely monitoring extensions of trade credit. We generally do not require collateral on trade receivables. We have a broad customer base doing business in many regions of the world. During 2019, 2018 and 2017, we did not have sales to any one customer in excess of 10% of sales. At those respective year-ends, no individual customer balances exceeded 10% of accounts receivable. We have a broad supplier base, sourcing our products in most regions of the world. During 2019, 2018 and 2017, we did not have purchases from any one vendor in excess of 10% of our inventory purchases. At those respective year-ends no individual vendor balance exceeded 10% of accounts payable. We maintain the majority of our cash and cash equivalents with several financial institutions. These financial institutions are located in many different geographical regions with varying economic characteristics and risks. Deposits held with banks may exceed insurance limits. We believe the risk of loss associated with our cash equivalents to be remote.
Adoption of New Accounting Standards and Recently Issued Accounting Standards	Adoption of New Accounting Standards: On January 1, 2019, we adopted ASU 2016-02, Leases, which requires the recognition of lease assets and lease liabilities for those leases classified as operating leases under previous guidance in Accounting Standards Codification 840. We adopted ASU 2016-02 using the modified retrospective approach. The guidance for this approach included an option to not restate comparative periods in transition and elect to use the effective date as the initial application of transition, which we elected. In addition, we elected the package of practical expedients permitted under the transition guidance within the new standard, which among other things, allowed us to carry forward the historical lease classifications. On January 1, 2019, we recorded an operating lease asset of $192 million and an operating lease liability of $208 million. The standard did not impact our consolidated net earnings or cash flows. Adoption of the new standard is more fully described in Note 7. Recently Issued Accounting Standards: In June 2016, the Financial Accounting Standards Board (“FASB”) issued ASU 2016-13, Measurement of Credit Losses on Financial Instruments, which requires that an entity measure impairment of certain financial instruments, including trade receivables, based on expected losses rather than incurred losses. This update is effective for annual and interim financial statement periods beginning after December 15, 2019, with early adoption permitted for financial statement periods beginning after December 15, 2018. In November 2018, the FASB issued ASU 2018-19 which clarifies guidance in ASU 2016-13. We do not expect the adoption of this standard to materially impact our consolidated financial statements. In December 2019, the FASB issued ASU 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes, an update intended to simplify various aspects related to accounting for income taxes. This guidance removes certain exceptions to the general principles in Topic 740 and clarifies and amends existing guidance to improve consistent application. This accounting standards update will be effective for annual and interim financial statement periods beginning after December 15, 2020, with early adoption permitted. We are currently evaluating the impact of this accounting standards update, but do not expect the adoption to materially impact our consolidated financial statements
