Accounting Policies [Abstract] | |
Significant Accounting Policies | 1. Significant Accounting Policies Description of Business CARBO Ceramics Inc. (the “Company”) was formed in 1987 and is a manufacturer of ceramic proppants and also produces resin-coated ceramic proppants. The Company has production plants in: New Iberia, Louisiana; Eufaula, Alabama; McIntyre, Georgia; Toomsboro, Georgia; and Millen, Georgia; and a sand processing facility in Marshfield, Wisconsin. The Company predominantly sells its proppant products through pumping service companies that perform hydraulic fracturing for oil and gas companies. Finished goods inventories are stored at the plant sites and various domestic and international remote distribution facilities. The Company also provides one of the industry’s most widely used hydraulic fracture simulation software FracPro ® Beginning in late 2014, a severe decline in oil and natural gas prices led to a significant decline in oil and natural gas industry drilling activities and capital spending. Beginning in 2015, the Company implemented a number of initiatives to preserve cash and lower costs, including: reducing workforce across the organization, lowering production output levels in order to align with lower demand, limiting capital expenditures and reducing dividends. The Company incurred severance costs of $287 and $6,426 during 2017 and 2016, respectively, as a result of these actions. Temporarily idled facilities are expected to remain closed for a short period of time, generally less than one year. Mothballed facilities are expected to remain closed for one year or longer. The accounting treatment is the same for both temporarily idled and mothballed facilities, except that mothballed assets are evaluated for possible impairment while temporarily idled assets are not necessarily assessed for impairment. The Company continues to depreciate both temporarily idled and mothballed assets. As of December 31, 2017, we are producing ceramic proppants predominantly from our Eufaula, Alabama manufacturing facility, and processing sand at our Marshfield, Wisconsin facility. We are currently producing ceramic pellets in a limited capacity at our McIntyre, Georgia facility. Our Millen, Georgia facility is currently mothballed and not expected to resume ceramic proppant production in the near future. We are currently using our Toomsboro, Georgia facility in a limited capacity to primarily process minerals for third parties. The Company continues to assess liquidity needs and manage cash flows and, if industry conditions do not improve and/or demand for its products does not otherwise increase, the Company would expect to temporarily idle all or a portion of our currently active facilities in the short term. As a result of the steps the Company has taken to enhance its liquidity, the Company currently believes that cash on hand will enable the Company to meet its working capital, capital expenditure, debt service and other funding requirements for at least one year from the date this Form 10-K is issued. The Company’s view regarding sufficiency of cash and liquidity is primarily based on our financial forecast for 2018, which is impacted by various assumptions regarding demand and sales prices for our products. Generally, we expect demand for our products and the sales prices to increase in 2018 compared to 2017, and this expectation is included within our 2018 financial forecast. Although we have observed certain factors in 2017 that support improving industry conditions, our financial forecasts in recent periods have proven less reliable given customer demand, which is highly volatile in the current operating environment and no committed sales backlog exists with our customers. As a result, there is no guarantee that our financial forecast, which projects sufficient cash will be available to meet planned operating expenses and other cash needs, will be accurate. Additionally, the Company suspended completion of two large construction projects. We suspended completion of the second production line at the Millen, Georgia facility indefinitely, and we are exploring way to monetize these assets. The second phase of the retrofit of our Eufaula, Alabama plant with the new KRYPTOSPHERE ® Principles of Consolidation The consolidated financial statements include the accounts of CARBO Ceramics Inc. and its operating subsidiaries. All significant intercompany transactions have been eliminated. Concentration of Credit Risk, Accounts Receivable and Other Receivables The Company performs periodic credit evaluations of its customers’ financial condition and generally does not require collateral. Receivables are generally due within 30 days. The majority of the Company’s receivables are from customers in the petroleum pressure pumping industry. The Company establishes an allowance for doubtful accounts based on its assessment of collectability risk and periodically evaluates the balance in the allowance based on a review of trade accounts receivable. Trade accounts receivable are periodically reviewed for collectability based on customers’ past credit history and current financial condition, and the allowance is adjusted if necessary. Credit losses historically have been insignificant. The allowance for doubtful accounts at December 31, 2017 and 2016 was $1,602 and $2,804, respectively. Other receivables were $546 and $650 as of December 31, 2017 and 2016, respectively, of which related mainly to miscellaneous receivables in the United States. Cash Equivalents The Company considers all highly liquid investments with a maturity of three months or less when purchased to be cash equivalents. The carrying amounts reported in the balance sheet for cash equivalents approximate fair value. Restricted Cash As a result of the repayment of the Wells Fargo term loan, combined with the continued use of letters of credit and corporate cards with Wells Fargo, a portion of the Company’s cash balance is now restricted to its use in order to provide collateral to Wells Fargo. As of December 31, 2017 and 2016, restricted cash was $10,216 and 0, respectively. Inventories Inventories are stated at the lower of cost (weighted average) or market. Finished goods inventories include costs of materials, plant labor and overhead incurred in the production of the Company’s products and costs to transfer finished goods to distribution centers. The Company evaluated the carrying values of its inventories and concluded that market prices had fallen below carrying costs for certain inventory. Consequently, the Company recognized $1,515 and $4,546 lower of cost or market adjustments in cost of sales in 2016 and 2015, respectively, to adjust finished goods and raw materials carrying values to the lower market prices. No adjustments were required in 2017. Property, Plant and Equipment Property, plant and equipment are stated at cost. Repair and maintenance costs are expensed as incurred. Depreciation is computed on the straight-line method for financial reporting purposes using the following estimated useful lives: Buildings and improvements 15 to 30 years Machinery and equipment 3 to 30 years Land-use rights 30 years The Company holds approximately 4,618 acres of land and leasehold interests containing kaolin reserves near its plants in Georgia and Alabama. The Company also holds approximately 113 acres of land and leasehold interests containing sand reserves near its sand processing facility in Marshfield, Wisconsin. The capitalized costs of land and mineral rights as well as costs incurred to develop such property are amortized using the units-of-production method based on estimated total tons of these reserves. Impairment of Long-Lived Assets and Intangible Assets Long-lived assets to be held and used and intangible assets that are subject to amortization are reviewed for impairment whenever events or circumstances indicate their carrying amounts might not be recoverable. Recoverability is assessed by comparing the undiscounted expected future cash flows from the assets with their carrying amount. If the carrying amount exceeds the sum of the undiscounted future cash flows an impairment loss is recorded. The impairment loss is measured by comparing the fair value of the assets with their carrying amounts. Intangible assets that are not subject to amortization are tested for impairment at least annually by comparing their fair value with the carrying amount and recording an impairment loss for any excess of carrying amount over fair value. Fair values are generally determined based on discounted expected future cash flows or appraised values, as appropriate. For additional information on the Company’s long-lived assets and intangible assets impairment assessment, please refer to Note 4 - Impairment of Long-Lived Assets. Manufacturing Production Levels Below Normal Capacity As a result of the Company substantially reducing manufacturing production levels, including by idling and mothballing certain facilities, the component of the Company’s accounting policy for inventory relating to operating at production levels below normal capacity was triggered and resulted in certain production costs being expensed instead of being capitalized into inventory. The Company expenses fixed production overhead amounts in excess of amounts that would have been allocated to each unit of production at normal production levels. For the years ended December 31, 2017, 2016 and 2015 the Company expensed $40,664, $47,318 and $33,724, respectively, in production costs. Capitalized Software The Company capitalizes certain software costs, after technological feasibility has been established, which are amortized utilizing the straight-line method over the economic lives of the related products, generally not to exceed five years. Goodwill Goodwill represents the excess of the cost of companies acquired over the fair value of their net assets at the date of acquisition. Goodwill relating to each of the Company’s reporting units is tested for impairment annually, during the fourth quarter, as well as when an event, or change in circumstances, indicates an impairment is more likely than not to have occurred. For additional information on the Company’s goodwill impairment assessment, please refer to Note 4 - Impairment of Long-Lived Assets. Revenue Recognition Revenue from proppant sales is recognized when title passes to the customer, generally upon delivery. Revenue from consulting and geotechnical services is recognized at the time service is performed. Revenue from the sale of fracture simulation software is recognized when title passes to the customer at time of shipment. Revenue from the sale of spill prevention services is recognized at the time service is performed. Revenue from the sale of containment goods is recognized at the time goods are delivered. Shipping and Handling Costs Shipping and handling costs are classified as cost of sales. Shipping costs consist of transportation costs to deliver products to customers. Handling costs include labor and overhead to maintain finished goods inventory and operate distribution facilities. Cost of Start-Up Activities Start-up activities, including organization costs, are expensed as incurred. Start-up costs for 2016 and 2015 related to the start-up of the first phase of a retrofit of an existing plant to produce KRYPTOSPHERE® products. There were no start-up costs for 2017. Use of Estimates The preparation of financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Actual results could differ from those estimates. Research and Development Costs Research and development costs are charged to operations when incurred and are included in Selling, General and Administrative expenses. The amounts incurred in 2017, 2016 and 2015 were $4,417, $3,817 and $7,047, respectively. New Accounting Pronouncements In November 2016, the FASB issued ASU No. 2016-18, “Statement of Cash Flows (Topic 230) – Restricted Cash,” which requires that a statement of cash flows explain the change during the period in the total of cash, cash equivalents, and amounts generally described as restricted cash or restricted cash equivalents. The Company adopted this guidance as of January 1, 2017. The adoption did not have a material impact on its consolidated financial statements and related disclosures. In February 2016, the FASB issued ASU No. 2016-02, “ Leases (Topic 842) In August 2015, the FASB issued ASU No. 2015-14, “Revenue from Contracts with Customers (Topic 606) – Deferral of the Effective Date,” which revises the effective date of ASU No. 2014-09, “Revenue from Contracts with Customers (Topic 606),” (“ASU 2014-09”) to interim and annual periods beginning after December 15, 2017, with early adoption permitted no earlier than interim and annual periods beginning after December 15, 2016. In May 2014, the FASB issued ASU 2014-09, which amends current revenue guidance. The core principle of the guidance is that an entity should recognize revenue 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. The Company’s analysis of sales contracts under ASC 606 supports the recognition of revenue at a point in time, typically when title passes to the customer upon delivery, for the majority of contracts, which is consistent with the current revenue recognition model. The Company utilized the modified retrospective approach, which requires a cumulative adjustment to retained earnings and no adjustments to prior periods. The Company adopted this guidance as of January 1, 2018. There was no material impact on the Company’s consolidated financial statements or disclosures. In July 2015, the FASB issued ASU No. 2015-11, “Inventory (Topic 330),” |

Debt Disclosure [Abstract] | |
Long-Term Debt and Notes Payable | 3. Long-Term Debt and Notes Payable On March 2, 2017, the Company entered into an Amended and Restated Credit Agreement (the “New Credit Agreement”) with Wilks Brothers, LLC (“Wilks”) to replace its current term loan with Wells Fargo Bank, National Association (“Wells Fargo”) and provide the Company with additional liquidity for a longer term. The New Credit Agreement is a $65,000 facility maturing on December 31, 2022, that consists of a $52,651 term loan that was made at closing to pay off Wells Fargo and an additional term loan of $12,349 that was made to the Company after the Company satisfied certain post-closing conditions. The $52,651 term loan was a non-cash transaction to the Company as Wilks directly paid Wells Fargo and assumed the New Credit Agreement. The Company’s obligations bear interest at 9.00% and are guaranteed by its two operating subsidiaries. No principal repayments are required until maturity (except in unusual circumstances), and there are no financial covenants. In lieu of making cash interest payments, the Company has the option during the first two years of the loan to make interest payments as payment-in-kind, or PIK, by applying an 11.00% rate to the interest payment due (instead of the 9.00% cash interest rate) and capitalizing the resulting amount to the outstanding principal balance of the loan. The Company is required to provide Wilks 30 day notice of its intent to exercise this option for an interest payment. The Company does not anticipate utilizing this option and has therefore accrued interest expense using the 9.00% cash interest rate. The loan cannot be prepaid during the first three years without making the lenders whole for interest that would have been payable over the entire remaining term of the loan. The Company’s obligations under the New Credit Agreement are secured by: (i) a pledge of all accounts receivable and inventory, (ii) cash in certain accounts, (iii) domestic distribution assets residing on owned real property, (iv) the Company’s Marshfield, Wisconsin and Toomsboro, Georgia plant facilities and equipment, and (v) certain real property interests in mines and minerals. Other liens previously in favor of Wells Fargo were released. As of December 31, 2017, the Company’s outstanding debt under its New Credit Agreement was $65,000. During the year ended December 31, 2017, the Company expensed $455 of debt issuance costs relating to the previous Wells Fargo Amended Credit Agreement. As of December 31, 2017, the Company had $853 of unamortized debt issuance costs relating to the New Credit Agreement that are presented as a direct reduction from the carrying amount of the long-term debt obligation. The Company had $9,230 and $11,980 in standby letters of credit issued through Wells Fargo as of December 31, 2017 and December 31, 2016, respectively, primarily as collateral relating to our natural gas commitments and railcar leases. As of December 31, 2016, the Company’s outstanding debt under its previous Wells Fargo Amended Credit Agreement was $55,901, of which $13,000 was classified as current and $42,901 was classified as long-term. As of December 31, 2016, the Company had $497 of debt issuance costs that are presented as a direct reduction from the carrying amount of the long-term debt obligation. For the year ended December 31, 2016, the weighted average interest rate was 6.447% based on LIBOR-based rate borrowings. On March 2, 2017, in connection with entry into the New Credit Agreement, the Company issued a Warrant (the “Warrant”) to Wilks. Subject to the terms of the Warrant, the Warrant entitles the holder thereof to purchase up to 523,022 shares of the Common Stock, at an exercise price of $14.91 per share, payable in cash. The Warrant expires on December 31, 2022. Based on a Form 4 filing with the SEC on December 29, 2017, Wilks owned approximately 11.4% of the Company’s outstanding common stock, and should Wilks fully exercise the Warrant to purchase an additional 523,022 shares, it would hold approximately 13.1% of the Company’s outstanding common stock. The Company allocated the proceeds received of $52,651 to each of these two instruments based on their relative fair values. Accordingly, the Company recorded long-term debt of $48,780 and warrants of $3,871 at inception. The amount associated with the Warrant was recorded as an increase to additional paid-in capital. The original issue discount of the long-term debt will be amortized using the effective interest method over the term of the loan. As of December 31, 2017, the unamortized original issue discount was $3,448. In May 2016, the Company received proceeds of $25,000 from the issuance of separate unsecured Promissory Notes (the “Notes”) to two of the Company’s Directors. Each Note matures on April 1, 2019 and bears interest at 7.00%. On March 2, 2017, in connection with the New Credit Agreement, the Notes were amended to provide for payment-in-kind, or PIK, interest payments at 8.00% until the lenders under the New Credit Agreement receive two consecutive semi-annual cash interest payments. On April 1, 2017, the Company made a $997 interest payment as PIK, and capitalized the resulting amount to the outstanding principal balance. On October 1, 2017, the Company made a $1,043 interest payment as PIK, and capitalized the resulting amount to the outstanding principal balance. As of March 7, 2018, the outstanding principal balance of the Notes was $27,040. Interest cost for the years ended December 31, 2017, 2016 and 2015 was $8,058, $6,022, and $2,973, respectively, of which $0, $80, and $2,038 was capitalized into the cost of property, plant and equipment in the years ended December 31, 2017, 2016, and 2015, respectively. Interest cost primarily includes interest expense relating to our debts as well as amortization and the write-off of debt issuance costs and amortization of the original issue discount associated with the New Credit Agreement and Warrant. |

Goodwill And Intangible Assets Disclosure [Abstract] | |
Impairment of Long-Lived Assets | 4. Impairment of Long-Lived Assets During 2017, 2016 and 2015, the Company recorded losses totaling $125,759, $1,065 and $43,697, respectively, on impairment of certain long-lived assets as market conditions changed with regard to demand for certain products offered by the Company. A decline in oil and natural gas prices during the second half of 2014 resulted in a severe decline in market conditions beginning in early 2015. During the fourth quarter of 2015, industry conditions further deteriorated as oil prices fell below $30 per barrel. As a result of these worsening conditions, the Company evaluated substantially all of its long-lived assets for possible impairment as of December 31, 2015. Key assumptions used in the analysis varied by facility. However, the overriding assumptions included: 1) the industry downturn would last longer than originally anticipated, taking up to five years to fully recover; 2) production levels would rise over the recovery period eventually returning to production levels within normal capacity; 3) market pricing would be similar to lower 2015 levels, thus conservatively reducing expected gross profit and thus cash flows; 4) the Company’s wet process manufacturing plants (Toomsboro and Millen, Georgia and Eufaula, Alabama) were evaluated as a group of assets because these facilities manufacture like products; and 5) other facilities were separately evaluated. Pursuant to that analysis, the Company determined that the projected gross cash flows attributable to certain assets did not exceed the carrying value of the assets; therefore, the Company concluded that there was indication of possible impairment. The Company engaged the services of a third party consulting firm to assist with the determination of the fair market value of the related assets and concluded that the assets were impaired. The key assumptions and inputs impacting the fair value analysis were the weighted average cost of capital and perpetuity growth rate as well as certain market data with respect to the property and equipment at each facility. As a result, during the year-ended December 31, 2015, the Company recorded a $36,177 impairment of long-lived assets, primarily relating to machinery and equipment at the McIntyre, Georgia manufacturing plant and Marshfield, Wisconsin sand processing facility. As of December 31, 2017, the remaining carrying value of the previously impaired assets at the McIntyre, Georgia manufacturing plant and Marshfield, Wisconsin sand processing facility was approximately $3,144. During the year-ended December 31, 2016, industry conditions remained depressed, but showed signs of improvement with oil prices above $50 per barrel. The Company evaluated substantially all of its long-lived assets for impairment as of December 31, 2016. Key assumptions were not materially different from the December 31, 2015 analysis, except that we evaluated the Eufaula facility separate from the Toomsboro and the Millen facilities given the completion of our KRYPTOSPHERE technology retrofitting in 2016. Pursuant to the December 31, 2016 analysis, the Company determined that the projected gross cash flows attributable to each asset group exceeded the carrying value; therefore, the Company concluded there was no impairment for the year-ended December 31, 2016. As of September 30, 2017, the Company concluded that the Company’s Toomsboro and Millen, Georgia facilities should no longer be evaluated together as a group of assets because the facilities are no longer interchangeable and will not manufacture like products. As a result of the sustained and long-term shift away from base ceramic proppant to less expensive frac sand, the Company has made a strategic decision to focus on growing technology, industrial and mineral processing revenue streams. Our Toomsboro, Georgia plant is being repurposed to produce technology and industrial products, as well as for use in toll processing of minerals. Our Millen, Georgia facility is currently only able to produce base ceramic proppants, but given our current long-term outlook on base ceramic proppant demand, we do not expect to utilize this plant to produce base ceramic proppant. We are currently evaluating opportunities to monetize our assets at our Millen facility. As a result, we evaluated the Toomsboro and Millen, Georgia plants separately for indicators of impairment during the third quarter of 2017. Given the change in the asset groupings of the two facilities and lack of estimated future cash flows associated with the base ceramic production at the Millen facility, the Company identified indicators of impairment at the Millen, Georgia facility as of September 30, 2017. The Company determined that the projected cash flows attributable to our Millen, Georgia facility did not exceed the carrying value of the assets; therefore the Company concluded there was an impairment at that facility. The Company engaged the services of a third party consulting firm to assist with the determination of the fair value of the related assets and concluded that the assets were impaired. The key assumptions and inputs impacting the fair value include third party data and commentary with respect to the property and equipment at our Millen facility. For machinery and equipment and construction in progress, we used a cost approach to estimate the valuation. We applied a 65 percent downward adjustment to calculated replacement cost based on an analysis of construction documents and historical expenditures to remove non-saleable soft costs such as engineering and installation that would have no value to a market participant. Based on discussions with market participants, a salvage value multiplier ranging from 12 percent to 50 percent of the remaining replacement cost basis was applied to arrive at the estimated fair value for the machinery and equipment and construction in progress subject to impairment. For real property, we used a market and cost approach and reconciled the two approaches. In using the market approach, we determined that the value of comparable property ranged from approximately $30 to $40 per square foot, and the concluded value of the property at the Millen facility was approximately $35 per square foot. In using the cost approach, we applied a 94% downward adjustment to the calculated value for the buildings and site improvements as a representation of economic obsolescence. As a result of these valuation procedures, which included the use of Level 3 inputs as defined in Note 9, the Company recognized a $125,759 impairment of long-lived assets, primarily relating to buildings, machinery and equipment, and construction in progress. As of September 30, 2017, as a result of our valuation procedures, the fair value of the Millen facility, including land, buildings, machinery and equipment and construction in progress, was approximately $18,786. As of September 30, 2017, related to the other asset groups, there were no events or circumstances that would indicate that carrying amounts of long-lived and other noncurrent assets might be impaired given that results for the first nine months of 2017 generally met our expectations from our analysis as of December 31, 2016 and given that our future outlook of cash flows associated with those asset groups has not significantly changed since that date. There were no additional indicators of impairment during the fourth quarter of 2017. As of December 31, 2017, the remaining carrying value of the impaired assets at the Millen facility was approximately $18,471, which included $6,753 classified as construction in progress. The Company also evaluated the carrying value of the long-term portion of bauxite raw materials. Much of the bauxite raw material was intended for use in production at the McIntyre facility. Based upon this evaluation, during 2016 and 2015, the Company recognized an impairment charge of $1,065 and $6,488, respectively, on the long-term portion of the bauxite raw material inventories. There was no such impairment during 2017. The Company assesses goodwill for possible impairment annually or sooner if circumstances indicate possible impairment may have occurred. The Company evaluated goodwill during the fourth quarter of 2015, and as a result of the further decline in the oil and natural gas industry during the fourth quarter of 2015, concluded that Asset Guard Products Inc. (“AGPI”) projected future cash flows were negatively impacted and thus indicated possible impairment of the AGPI goodwill. AGPI was formerly known as Falcon Technologies and Services, Inc. The Company engaged a third party to assist in the evaluation and concluded that impairment had occurred. Fair value, which was determined using a discounted cash flows method, fell below the carrying value. Consequently, during the fourth quarter of 2015, the Company recorded an $8,664 impairment of AGPI goodwill and an $833 impairment of the indefinite-lived AGPI Trademark intangible asset, both the full value of each of those assets. Evaluation of the StrataGen goodwill resulted in no indication of possible impairment. There were no such impairments during 2017 or 2016. During the years ended December 31, 2017, 2016 and 2015, the Company recognized a loss of $19, gain of $176, and gain of $230, respectively, on disposal of various assets. Components of loss (gain) on disposal or impairment of assets are as follows: For the years ended December 31, 2017 2016 2015 Domestic long-lived assets impairment $ 125,759 $ 1,065 $ 42,664 China assets impairment — — 1,033 Goodwill and intangible assets impairment — — 9,497 China CTA gain realization — — (8,853 ) Loss (gain) on disposal of assets 19 (176 ) (230 ) Total $ 125,778 $ 889 $ 44,111 |

Income Taxes | 6. Income Taxes Deferred income taxes reflect the net tax effects of temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts used for income tax purposes. Significant components of the Company’s deferred tax assets and liabilities as of December 31 are as follows: 2017 2016 Deferred tax assets: Employee benefits $ 836 $ 1,349 Inventories 2,309 8,811 Natural gas derivatives 610 1,281 Goodwill & other intangibles 3,179 4,881 Net operating loss 59,536 51,722 Foreign tax credits 667 — Other 2,029 2,028 Total deferred tax assets 69,166 70,072 Deferred tax liabilities: Depreciation 14,332 71,308 Indefinite-lived intangibles 209 — Foreign 26 — Total deferred tax liabilities 14,567 71,308 Valuation Allowance 54,829 — Net deferred tax liabilities $ (230 ) $ (1,236 ) Significant components of the provision for income taxes for the years ended December 31 are as follows: 2017 2016 2015 Current: Federal $ (375 ) $ (495 ) $ 1,509 State (99 ) (496 ) 120 Foreign 581 445 966 Total current 107 (546 ) 2,595 Deferred (2,134 ) (50,535 ) (56,800 ) $ (2,027 ) $ (51,081 ) $ (54,205 ) The reconciliation of income taxes computed at the U.S. statutory tax rate to the Company’s income tax expense for the years ended December 31 is as follows: 2017 2016 2015 Amount Percent Amount Percent Amount Percent U.S. statutory rate $ (89,300 ) (35.0 )% $ (45,923 ) (35.0 )% $ (57,312 ) (35.0 )% State income taxes, net of federal tax benefit (5,684 ) (2.2 ) (3,283 ) (2.5 ) (3,474 ) (2.1 ) Mining depletion (619 ) (0.2 ) (378 ) (0.3 ) (1,557 ) (0.9 ) Change in election for foreign tax credits (667 ) (0.3 ) (2,753 ) (2.1 ) 1,442 0.9 Foreign tax assets valuation allowance — — — — 1,230 0.7 Foreign investments 8,569 3.4 (323 ) (0.2 ) 847 0.5 Stock compensation excess tax deficiency 876 0.3 789 0.6 — — Other permanent differences 1,806 0.7 790 0.6 4,619 2.8 Tax reform deferred rate change 28,163 11.0 — — — — Valuation allowance 54,829 21.5 — — — — $ (2,027 ) (0.8 )% $ (51,081 ) (38.9 )% $ (54,205 ) (33.1 )% As a result of the significant decline in oil and gas activities and net losses incurred over the past several quarters, the Company determined during the year ending December 31, 2017 that it was more likely than not that a portion of our deferred tax assets will not be realized in the future. Accordingly, we established a $54,829 valuation allowance against our deferred tax assets. Our assessment of the realizability of our deferred tax assets is based on the weight of all available evidence, both positive and negative, including future reversals of deferred tax liabilities. In December 2017, the Tax Cuts and Jobs Act (“Tax Legislation”) was enacted. The Tax Legislation significantly revises the U.S. corporate income tax by, among other things, lowering corporate income tax rates, implementing the territorial tax system and imposing a repatriation tax on deemed repatriated earnings of foreign subsidiaries. As of December 31, 2017, the Company has not completed its accounting for the tax effects of enactment of the Tax Act. The Securities and Exchange Commission issued Staff Accounting Bulletin No. 118, or SAB 118, to address the accounting and reporting of the Tax Legislation. SAB 118 allows companies to take a reasonable period, which should not extend beyond one year from enactment of the Tax Legislation, to measure and recognize the effects of the new tax law. The Company has made a reasonable estimate of the effects on existing deferred tax balances and recognized a provisional reduction of approximately $28,163 in the Company’s net deferred tax assets before consideration of the valuation allowance, due primarily to the remeasurement of U.S. deferred tax assets at the lower enacted corporate rate. The Company recorded the adjustment during the fourth quarter of 2017; however, because of an offsetting change in our valuation allowance, there was zero net impact to net income during 2017 as a result of the legislation. The Company is still analyzing certain aspects of the Tax Legislation and refining its calculations, which could potentially affect the measurement of these balances or potentially give rise to new deferred tax amounts. The Company will complete this analysis within the measurement period in accordance with SAB 118. The Company also continues to evaluate the impacts of the newly enacted global intangible low-taxed income (“GILTI”) provisions which subject the Company’s foreign earnings to a minimum level of tax. Because of the complexities of the new legislation, the Company has not elected an accounting policy for GILTI at this time. Recent FASB guidance indicates that accounting for GILTI either as part of deferred taxes or as a period cost are both acceptable methods. Once further information is gathered and interpretation and analysis of the tax legislation evolves, the Company will make an appropriate accounting method election. Provision has been made for deferred U.S. income taxes on all foreign earnings based on the Company’s intent to repatriate foreign earnings. During the years ended December 31, 2017 and 2016, the Company did not recognize benefits on foreign investments due to the uncertainty of the Company being able to realize the foreign tax assets in light of current market conditions in China and Russia. This treatment decreased (increased) income tax benefit by $8,569 and ($323) for the years ended December 31, 2017 and 2016, respectively. During 2017, 2016, and 2015, the Company incurred a net operating loss in the United States. Net operating losses associated with the 2015 tax return have been carried back in full, while certain of the net operating losses incurred in 2016 and 2017 are carried forward to offset future taxable income. The cumulative recorded tax benefit of these net operating loss carryforwards totals $59,536 and $51,722 as of December 31, 2017 and 2016, respectively, and is included in the deferred income tax asset on those respective dates. The recorded tax benefit of $59,536 as of December 31, 2017 includes the impact of the change in corporate income tax rate following the enactment of the Tax Legislation. The Company filed amended 2013 and 2014 Federal income tax returns to claim $37,397 of the tax benefit which was received as a refund in April 2016. After finalization of the 2015 Federal return and a change in the attribute of the NOL carryback, additional refunds for 2012 through 2014 tax years are being claimed in the amount of $2,206. These amounts are included within income tax receivable as of December 31, 2017. The federal NOLs generated in 2017 and 2016 will be carried forward until they are utilized or their expiration in 2037 and 2036, respectively. The Company elected to claim bonus tax depreciation totaling $29,221 and $61,781 on assets placed in service in the United States during 2015 and 2014, respectively. This election increased the net operating loss in 2015 and reduced current taxable income in 2014. No such bonus depreciation was elected in 2016 and is not anticipated for 2017. The Company has not recognized any uncertain tax positions as of December 31, 2017. The reserve recorded as of December 31, 2015 of $153 was associated with a period no longer subject to audit and thus was reduced to $0 during 2016. The Company files its tax returns as prescribed by the tax laws of the jurisdictions in which it operates, the most significant of which are U.S. federal and certain state jurisdictions. In 2016, the Company received an audit notice from the Internal Revenue Service for periods 2013-2015. The Company does not anticipate any material findings. The 2016 federal tax year is also subject to examination. Various U.S. state jurisdiction tax years remain open to examination as well, although the Company believes assessments, if any, would be immaterial to its consolidated financial statements. |

Derivative Instruments And Hedging Activities Disclosure [Abstract] | |
Natural Gas Derivative Instruments | 8. Natural Gas Derivative Instruments Natural gas is used to fire the kilns at the Company’s manufacturing plants. In an effort to mitigate potential volatility in the cost of natural gas purchases and reduce exposure to short-term spikes in the price of this commodity, from time to time, the Company enters into contracts to purchase a portion of the anticipated monthly natural gas requirements at specified prices. Contracts are geographic by plant location. Historically, the Company has taken delivery of all natural gas quantities under contract, which exempted the Company from accounting for the contracts as derivative instruments. However, due to the severe decline in industry activity beginning in early 2015, the Company significantly reduced production levels and consequently did not take delivery of all of the contracted natural gas quantities. As a result, the Company began to account for relevant contracts as derivative instruments. Derivative accounting requires the natural gas contracts to be recognized as either assets or liabilities at fair value with an offsetting entry in earnings. The Company uses the income approach in determining the fair value of these derivative instruments. The model used considers the difference, as of each balance sheet date, between the contracted prices and the New York Mercantile Exchange (“NYMEX”) forward strip price for each contracted period. The estimated cash flows from these contracts are discounted using a discount rate of 8.0%, which reflects the nature of the contracts as well as the timing and risk of estimated cash flows associated with the contracts. The discount rate had an immaterial impact on the fair value of the contracts for the year ended December 31, 2017 and 2016. The last natural gas contract will expire in December 2018. As a result, during the year ended December 31, 2017 and 2016, the Company recognized a loss on derivative instruments of $917 and a gain on derivative instruments of $1,886, respectively in cost of sales. The cumulative present value of the losses on these natural gas derivative contracts as of December 31, 2017 and 2016 are presented as current and long-term liabilities, as applicable, in the Consolidated Balance Sheet. At December 31, 2017, the Company has contracted for delivery a total of 1,800,000 MMBtu of natural gas at an average price of $4.40 per MMBtu through December 31, 2018. Contracts covering 1,680,000 MMBtu are subject to accounting as derivative instruments. Future decreases in the NYMEX forward strip prices will result in additional derivative losses while future increases in the NYMEX forward strip prices will result in derivative gains. Future gains or losses will approximate the change in NYMEX natural gas prices relative to the total quantity of natural gas under contracts now subject to accounting as derivatives. The historical average NYMEX natural gas contract settlement prices for the years ended December 31, 2017 and 2016 were $3.11 per MMBtu and $2.46 per MMBtu, respectively. |

Fair Value Disclosures [Abstract] | |
Fair Value Measurements | 9. Fair Value Measurements The Company’s derivative instruments are measured at fair value on a recurring basis. U.S. GAAP establishes a fair value hierarchy that has three levels based on the reliability of the inputs used to determine the fair value. These levels include: Level 1, defined as inputs such as unadjusted quoted prices in active markets for identical assets or liabilities; Level 2, defined as inputs other than quoted prices in active markets that are either directly or indirectly observable; and Level 3, defined as unobservable inputs for use when little or no market data exists, therefore requiring an entity to develop its own assumptions. The Company’s natural gas derivative instruments are included within the Level 2 fair value hierarchy. For additional information on the derivative instruments, refer to Note 8 – Natural Gas Derivative Instruments. The following table sets forth by level within the fair value hierarchy the Company’s assets and liabilities that were accounted for at fair value: Fair value as of December 31, 2017 Level 1 Level 2 Level 3 Total Liabilities: Derivative instruments $ — $ (2,537 ) $ — $ (2,537 ) Total fair value $ — $ (2,537 ) $ — $ (2,537 ) Fair value as of December 31, 2016 Level 1 Level 2 Level 3 Total Liabilities: Derivative instruments $ — $ (3,468 ) $ — $ (3,468 ) Total fair value $ — $ (3,468 ) $ — $ (3,468 ) At December 31, 2017, the fair value of the Company’s long-term debt approximated the carrying value. |

Stock Based Compensation | 10. Stock Based Compensation On May 20, 2014, the shareholders approved the 2014 CARBO Ceramics Inc. Omnibus Incentive Plan (the “2014 Omnibus Incentive Plan”). The 2014 Omnibus Incentive Plan replaces the expired 2009 Omnibus Incentive Plan. In May 2017, the shareholders approved the Amended and Restated 2014 CARBO Ceramics Inc. Omnibus Incentive Plan (the “Amended 2014 Omnibus Plan”). Under the Amended 2014 Omnibus Incentive Plan, the Company may grant cash-based awards, stock options (both non-qualified and incentive) and other equity-based awards (including stock appreciation rights, phantom stock, restricted stock, restricted stock units, performance shares, deferred share units or share-denominated performance units) to employees and non-employee directors. The amount paid under the Amended 2014 Omnibus Incentive Plan to any single participant in any calendar year with respect to any cash-based award shall not exceed $5,000. Awards may be granted with respect to a number of shares of the Company’s Common Stock that in the aggregate does not exceed 1,450,000 shares prior to the fifth anniversary of its effective date, plus (i) the number of shares that are forfeited, cancelled or returned, and (ii) the number of shares that are withheld from the participants to satisfy an option exercise price or minimum statutory tax withholding obligations. No more than 100,000 shares may be granted to any single participant in any calendar year. Equity-based awards may be subject to performance-based and/or service-based conditions. With respect to stock options and stock appreciation rights granted, the exercise price shall not be less than the market value of the underlying Common Stock on the date of grant. The maximum term of an option is ten years. Restricted stock awards granted generally vest (i.e., transfer and forfeiture restrictions on these shares are lifted) proportionately on each of the first three anniversaries of the grant date, but subject to certain limitations, awards may specify other vesting periods. As of December 31, 2017, 759,326 shares were available for issuance under the Amended 2014 Omnibus Incentive Plan. A summary of restricted stock activity and related information for the year ended December 31, 2017 is presented below: Weighted- Average Grant-Date Fair Value Shares Per Share Nonvested at January 1, 2017 339,140 $ 28.59 Granted 297,685 $ 10.30 Vested (145,643 ) $ 36.69 Forfeited (50,063 ) $ 17.19 Nonvested at December 31, 2017 441,119 $ 14.87 As of December 31, 2017, there was $3,183 of total unrecognized compensation cost related to restricted shares granted under Amended and Restated 2014 Omnibus Incentive Plan. That cost is expected to be recognized over a weighted-average period of 1.6 years. The weighted-average grant date fair value of restricted stock granted during the years ended December 31, 2017, 2016 and 2015 was $10.30, $17.27 and $34.62, respectively. The total fair value of shares vested during the years ended December 31, 2017, 2016 and 2015 was $2,023, $6,532 and $6,910, respectively. As of December 31, 2017, the Company’s outstanding market-based cash awards to certain executives of the Company had a total Target Award of $2,822. The amount of awards that will ultimately vest can range from 0% to 200% based on the Company’s Relative Total Shareholder Return calculated over a three year period beginning January 1 of the year each grant was made. The Company also made phantom stock awards to key employees pursuant to the Amended 2014 Omnibus Incentive Plan. The units subject to an award vest and cease to be forfeitable in equal annual installments over a three-year period. Participants awarded units of phantom stock are entitled to a lump sum cash payment equal to the fair market value of a share of Common Stock on the vesting date. In no event will Common Stock of the Company be issued with regard to outstanding phantom stock awards. As of December 31, 2017, there were 163,215 units of phantom stock granted under the Amended 2014 Omnibus Incentive Plan, of which 4,189 have vested and 12,950 have been forfeited. As of December 31, 2017, nonvested units of phantom stock under the Amended 2014 Omnibus Incentive Plan have a total value of $1,487, a portion of which is accrued as a liability within Accrued Payroll and Benefits. |

In November 2017, the Company entered into an agreement with a supplier to provide hydro sized sand for the Company’s Marshfield, Wisconsin plant at a specified contract price. The Company agreed to purchase a minimum of 40,000 tons with the option to purchase additional hydro sized sand at the Company’s discretion. As of December 31, 2017, the Company had not yet purchased any hydro sized sand under this agreement. The Company entered into a lease agreement dated November 1, 2008 (“2008 Agreement”) with the Development Authority of Wilkinson County (the “Wilkinson County Development Authority”) and a lease agreement dated November 1, 2012 (“2012 Agreement”) with the Development Authority of Jenkins County (the “Jenkins County Development Authority” and together with the Wilkinson County Development Authority, the “Development Authorities”) each in the State of Georgia. Pursuant to the 2008 Agreement, the Wilkinson County Development Authority holds the title to the real and personal property of the Company's McIntyre and Toomsboro manufacturing facilities and leases the facilities to the Company for an annual rental fee of $50 per year through November 1, 2017, and includes a Company renewal option to extend through November 1, 2021. Pursuant to the 2012 Agreement, the Jenkins County Development Authority holds title to the real estate and personal property of the Company’s Millen, Georgia manufacturing facility, and leases the facility to the Company until the tenth anniversary of completion of the final phase of the facility. At any time prior to the scheduled termination of either lease, the Company has the option to terminate the lease and purchase the property for a nominal fee plus the payment of any rent payable through the balance of the lease term. Furthermore, the Company has security interests in the titles held by the Development Authorities. The Company has also entered into a Memorandum of Understanding (the “MOU”) with the Development Authorities and other local agencies, under which the Company receives tax incentives in exchange for its commitment to invest in the county and increase employment. The MOU with the Jenkins County Development Authority also requires the Company to pay an administrative payment of $50 per year during the term of the Millen lease. The Company is required to achieve certain employment levels in order to retain its tax incentives. In the event the Company does not meet the agreed-upon employment targets or the MOU is otherwise terminated, the Company would be subjected to additional property taxes annually. Based on adverse economic conditions beyond the Company’s control that negatively impacted employment levels, a notice dated December 1, 2015 sent by the Company to the Development Authority of Jenkins County declared a force majeure, which suspended employment levels defined in the original agreement and preserved tax incentives until further notification of the restart of plant operations. The suspension period defined in the amended agreement cannot extend beyond January 1, 2021. Based on adverse economic conditions beyond the Company’s control that negatively impacted employment levels, a notice dated February 1, 2016 sent by the Company to the Development Authority of Wilkinson County declared a force majeure, which suspended employment levels defined in the original agreement and preserved tax incentives until further notification of the restart of plant operations. The Development Authority of Jenkins County and the Development Authority of Wilkinson County has not challenged the Company’s declaring a force majeure. The properties subject to these lease agreements are included in Property, Plant and Equipment (net book value of $262,319 at December 31, 2017) in the accompanying consolidated financial statements. |

Sale of Russian Proppant Business | 17. Sale of Russian Proppant Business On July 21, 2017, subsidiaries of the Company Carbo Ceramics (Mauritius) Inc. and Carbo LLC (together, the “Sellers”) entered into a Share Purchase Agreement with Petro Welt Technologies AG and PeWeTe Evolution Limited (together, the “Purchasers”) to sell the Company’s Russian proppant business. The adjusted purchase price is approximately $26,000 for all of the shares of CARBO Ceramics Cyprus Limited held by the Sellers. The transaction received local regulatory approval and closed on September 21, 2017. During the third quarter of 2017, the Company received gross proceeds of $22,000 related to the sale. We expect to receive additional proceeds on the sale of approximately $4,000 related to net debt and net working capital purchase price adjustments. Although the Company remains in active discussions with the Purchasers regarding the purchase price adjustments, in January 2018, the Company filed a Notice of Arbitration related to this purchase price adjustment against the Purchasers. The net assets included in the calculation of the loss on the sale were $17,754, including cash and cash equivalents of $846, accounts receivable of $6,047, total inventory of $8,573, net PP&E of $2,763, other net assets of $670, and accrued expenses of $1,145. The Company incurred approximately $1,646 in expenses relating to the sale. Gain on the sale before consideration of the cumulative translation adjustment was approximately $6,599. However, as a result of the sale, the Company reclassified the foreign currency cumulative translation loss of $33,347 from accumulated other comprehensive loss within shareholders’ equity to net loss which offset the initial gain on the sale. As a result, the Company’s net loss on the sale was approximately $26,747, presented as a separate line item within operating loss on the consolidated statement of operations.

Accounting Policies [Abstract] | |
Principles of Consolidation | Principles of Consolidation The consolidated financial statements include the accounts of CARBO Ceramics Inc. and its operating subsidiaries. All significant intercompany transactions have been eliminated. |
Concentration of Credit Risk, Accounts Receivable and Other Receivables | Concentration of Credit Risk, Accounts Receivable and Other Receivables The Company performs periodic credit evaluations of its customers’ financial condition and generally does not require collateral. Receivables are generally due within 30 days. The majority of the Company’s receivables are from customers in the petroleum pressure pumping industry. The Company establishes an allowance for doubtful accounts based on its assessment of collectability risk and periodically evaluates the balance in the allowance based on a review of trade accounts receivable. Trade accounts receivable are periodically reviewed for collectability based on customers’ past credit history and current financial condition, and the allowance is adjusted if necessary. Credit losses historically have been insignificant. The allowance for doubtful accounts at December 31, 2017 and 2016 was $1,602 and $2,804, respectively. Other receivables were $546 and $650 as of December 31, 2017 and 2016, respectively, of which related mainly to miscellaneous receivables in the United States. |
Cash Equivalents | Cash Equivalents The Company considers all highly liquid investments with a maturity of three months or less when purchased to be cash equivalents. The carrying amounts reported in the balance sheet for cash equivalents approximate fair value. |
Restricted Cash | Restricted Cash As a result of the repayment of the Wells Fargo term loan, combined with the continued use of letters of credit and corporate cards with Wells Fargo, a portion of the Company’s cash balance is now restricted to its use in order to provide collateral to Wells Fargo. As of December 31, 2017 and 2016, restricted cash was $10,216 and 0, respectively. |
Inventories | Inventories Inventories are stated at the lower of cost (weighted average) or market. Finished goods inventories include costs of materials, plant labor and overhead incurred in the production of the Company’s products and costs to transfer finished goods to distribution centers. The Company evaluated the carrying values of its inventories and concluded that market prices had fallen below carrying costs for certain inventory. Consequently, the Company recognized $1,515 and $4,546 lower of cost or market adjustments in cost of sales in 2016 and 2015, respectively, to adjust finished goods and raw materials carrying values to the lower market prices. No adjustments were required in 2017. |
Property, Plant and Equipment | Property, Plant and Equipment Property, plant and equipment are stated at cost. Repair and maintenance costs are expensed as incurred. Depreciation is computed on the straight-line method for financial reporting purposes using the following estimated useful lives: Buildings and improvements 15 to 30 years Machinery and equipment 3 to 30 years Land-use rights 30 years The Company holds approximately 4,618 acres of land and leasehold interests containing kaolin reserves near its plants in Georgia and Alabama. The Company also holds approximately 113 acres of land and leasehold interests containing sand reserves near its sand processing facility in Marshfield, Wisconsin. The capitalized costs of land and mineral rights as well as costs incurred to develop such property are amortized using the units-of-production method based on estimated total tons of these reserves. |
Impairment of Long-Lived Assets and Intangible Assets | Impairment of Long-Lived Assets and Intangible Assets Long-lived assets to be held and used and intangible assets that are subject to amortization are reviewed for impairment whenever events or circumstances indicate their carrying amounts might not be recoverable. Recoverability is assessed by comparing the undiscounted expected future cash flows from the assets with their carrying amount. If the carrying amount exceeds the sum of the undiscounted future cash flows an impairment loss is recorded. The impairment loss is measured by comparing the fair value of the assets with their carrying amounts. Intangible assets that are not subject to amortization are tested for impairment at least annually by comparing their fair value with the carrying amount and recording an impairment loss for any excess of carrying amount over fair value. Fair values are generally determined based on discounted expected future cash flows or appraised values, as appropriate. For additional information on the Company’s long-lived assets and intangible assets impairment assessment, please refer to Note 4 - Impairment of Long-Lived Assets. |
Manufacturing Production Levels Below Normal Capacity | Manufacturing Production Levels Below Normal Capacity As a result of the Company substantially reducing manufacturing production levels, including by idling and mothballing certain facilities, the component of the Company’s accounting policy for inventory relating to operating at production levels below normal capacity was triggered and resulted in certain production costs being expensed instead of being capitalized into inventory. The Company expenses fixed production overhead amounts in excess of amounts that would have been allocated to each unit of production at normal production levels. For the years ended December 31, 2017, 2016 and 2015 the Company expensed $40,664, $47,318 and $33,724, respectively, in production costs. |
Capitalized Software | Capitalized Software The Company capitalizes certain software costs, after technological feasibility has been established, which are amortized utilizing the straight-line method over the economic lives of the related products, generally not to exceed five years. |
Goodwill | Goodwill Goodwill represents the excess of the cost of companies acquired over the fair value of their net assets at the date of acquisition. Goodwill relating to each of the Company’s reporting units is tested for impairment annually, during the fourth quarter, as well as when an event, or change in circumstances, indicates an impairment is more likely than not to have occurred. For additional information on the Company’s goodwill impairment assessment, please refer to Note 4 - Impairment of Long-Lived Assets. |
Revenue Recognition | Revenue Recognition Revenue from proppant sales is recognized when title passes to the customer, generally upon delivery. Revenue from consulting and geotechnical services is recognized at the time service is performed. Revenue from the sale of fracture simulation software is recognized when title passes to the customer at time of shipment. Revenue from the sale of spill prevention services is recognized at the time service is performed. Revenue from the sale of containment goods is recognized at the time goods are delivered. |
Shipping and Handling Costs | Shipping and Handling Costs Shipping and handling costs are classified as cost of sales. Shipping costs consist of transportation costs to deliver products to customers. Handling costs include labor and overhead to maintain finished goods inventory and operate distribution facilities. |
Cost of Start-Up Activities | Cost of Start-Up Activities Start-up activities, including organization costs, are expensed as incurred. Start-up costs for 2016 and 2015 related to the start-up of the first phase of a retrofit of an existing plant to produce KRYPTOSPHERE® products. There were no start-up costs for 2017. |
Use of Estimates | Use of Estimates The preparation of financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Actual results could differ from those estimates. |
Research and Development Costs | Research and Development Costs Research and development costs are charged to operations when incurred and are included in Selling, General and Administrative expenses. The amounts incurred in 2017, 2016 and 2015 were $4,417, $3,817 and $7,047, respectively. |
New Accounting Pronouncements | New Accounting Pronouncements In November 2016, the FASB issued ASU No. 2016-18, “Statement of Cash Flows (Topic 230) – Restricted Cash,” which requires that a statement of cash flows explain the change during the period in the total of cash, cash equivalents, and amounts generally described as restricted cash or restricted cash equivalents. The Company adopted this guidance as of January 1, 2017. The adoption did not have a material impact on its consolidated financial statements and related disclosures. In February 2016, the FASB issued ASU No. 2016-02, “ Leases (Topic 842) In August 2015, the FASB issued ASU No. 2015-14, “Revenue from Contracts with Customers (Topic 606) – Deferral of the Effective Date,” which revises the effective date of ASU No. 2014-09, “Revenue from Contracts with Customers (Topic 606),” (“ASU 2014-09”) to interim and annual periods beginning after December 15, 2017, with early adoption permitted no earlier than interim and annual periods beginning after December 15, 2016. In May 2014, the FASB issued ASU 2014-09, which amends current revenue guidance. The core principle of the guidance is that an entity should recognize revenue 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. The Company’s analysis of sales contracts under ASC 606 supports the recognition of revenue at a point in time, typically when title passes to the customer upon delivery, for the majority of contracts, which is consistent with the current revenue recognition model. The Company utilized the modified retrospective approach, which requires a cumulative adjustment to retained earnings and no adjustments to prior periods. The Company adopted this guidance as of January 1, 2018. There was no material impact on the Company’s consolidated financial statements or disclosures. In July 2015, the FASB issued ASU No. 2015-11, “Inventory (Topic 330),” |
