Organization, Consolidation and Presentation of Financial Statements [Abstract]
Business and Organization	Business and Organization Description of Business and Organization Hi-Crush Inc. (together with its subsidiaries, the "Company," "we," "us" or "our") is a fully-integrated, strategic provider of technology and logistics solutions to the North American petroleum industry. Our integrated suite of offerings, including software, range of equipment solutions for wellsite storage and delivery of proppant, owned and operated terminals, and frac sand mining facilities, as well as third party sourcing for proppant, provides mine-to-wellsite logistics solutions in all major oil and gas basins in the United States. The Company and the chief operating decision maker view the Company’s operations and manage its business as one operating segment. This reporting segment of the Company is evaluated regularly by the chief operating decision maker in deciding how to allocate resources and in assessing performance. On May 31, 2019, the Company completed its conversion (the "Conversion") from a Delaware limited partnership named Hi-Crush Partners LP to a Delaware corporation named Hi-Crush Inc. As a result of and at the effective date of the Conversion, each common unit representing limited partnership interests in Hi-Crush Partners LP ("common units") issued and outstanding immediately prior to the Conversion was automatically converted into one share of common stock, par value $0.01 per share, of Hi-Crush Inc. ("common stock"). Because the conversion became effective on May 31, 2019, the prior-period amounts in the accompanying Condensed Consolidated Financial Statements as of December 31, 2018 and for the three and six months ended June 30, 2018, reflect Hi-Crush as a limited partnership, not a corporation through May 31, 2019. In this report, references to "Hi-Crush," the "Company," "we," "us" or "our" refer to (i) Hi-Crush Inc. and its subsidiaries for periods following the Conversion and (ii) Hi-Crush Partners LP and its subsidiaries for periods prior to the Conversion, in each case, except where the context otherwise requires. References to common units for periods prior to the Conversion, and references to common units for periods following the Conversion means shares of common stock. As a result of the Conversion, the financial impact to the Condensed Consolidated Financial Statements contained herein consisted of (i) reclassification of partnership equity accounts to equity accounts reflective of a corporation and (ii) income tax effects. Refer to Note 2 - Significant Accounting Policies for the income tax effects of the Conversion and refer to Note 11 - Equity for the impact of the Conversion on Hi-Crush's equity. On May 7, 2019, the Company completed the acquisition of Proppant Logistics LLC ("Proppant Logistics"), which owns Pronghorn Logistics, LLC ("Pronghorn"), a leading provider of end-to-end proppant logistics services. On January 18, 2019, the Company completed the acquisition of BulkTracer Holdings LLC ("BulkTracer"), the owner of a logistics software system, PropDispatch. On October 21, 2018, the Company acquired all of the then outstanding membership interests in our former sponsor, Hi-Crush Proppants LLC (the "sponsor") and the non-economic general partner interest to Hi-Crush GP LLC (the "general partner") in the Company (the "Sponsor Contribution"). In connection with the acquisition, all of the outstanding incentive distribution rights representing limited partnership interests in the Company were canceled and extinguished and the sponsor waived any and all rights to receive contingent consideration payments from the Company or our subsidiaries pursuant to certain previously entered into contribution agreements to which it was a party. On August 1, 2018, the Company completed the acquisition of FB Industries Inc. ("FB Industries"), a company engaged in the engineering, design and marketing of silo-based frac sand management systems. Refer to Note 3 - Acquisitions for additional disclosure regarding recent acquisitions. Basis of Presentation The accompanying unaudited interim Condensed Consolidated Financial Statements ("interim financial statements") of the Company have been prepared in accordance with accounting principles generally accepted in the United States ("GAAP") for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X issued by the U.S. Securities and Exchange Commission ("SEC"). Accordingly, they do not include all of the information and footnotes required by GAAP for complete financial statements. In the opinion of management, all normal and recurring adjustments and disclosures necessary for a fair statement are reflected in the interim periods presented. The results reported in these interim financial statements are not necessarily indicative of the results that may be reported for the entire year. These interim financial statements should be read in conjunction with the Company’s Consolidated Financial Statements for the year ended December 31, 2018 , which are included in the Company’s Annual Report on Form 10-K filed with the SEC on February 20, 2019 . The year-end balance sheet data was derived from the audited financial statements. Certain amounts in the prior period financial statements have been reclassified to conform to the presentation of the current period financial statements as it relates to the reclassification of depreciation and amortization separately from general and administrative expenses on the Condensed Consolidated Statements of Operations. These reclassifications had no effect on the previously reported results of operations. The Sponsor Contribution was accounted for as a transaction between entities under common control whereby the net assets of the sponsor and general partner were recorded at their historical cost. Therefore, the Company's historical financial information has been recast to combine the sponsor and general partner with the Company as if the combination had been in effect since inception of the common control.

Accounting Policies [Abstract]
Significant Accounting Policies	Significant Accounting Policies In addition to the significant accounting policies listed below, a comprehensive discussion of our critical accounting policies and estimates is included in our Annual Report on Form 10-K filed with the SEC on February 20, 2019 . Use of Estimates The preparation of the financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amount of assets and liabilities and disclosure of contingent liabilities at the date of the financial statements and the reported amount of revenues and expenses during the reporting period. Actual results could differ from those estimates. Accounts Receivable Trade receivables relate to sales of frac sand, related services and the sale of logistics equipment for which credit is extended based on the customer’s credit history and are recorded at the invoiced amount and do not bear interest. The Company regularly reviews the collectability of accounts receivable. When it is probable that all or part of an outstanding balance will not be collected, the Company establishes or adjusts an allowance as necessary, generally using the specific identification method. Account balances are charged against the allowance after all means of collection have been exhausted and potential recovery is considered remote. As of each of June 30, 2019 and December 31, 2018 , the Company maintained an allowance for doubtful accounts of $1,060 . Impairment of Long-lived Assets Recoverability of investments in property, plant and equipment, and other long-lived assets is evaluated annually, or more often if events or circumstances indicate the impairment of an asset may exist, based on reporting units, which management has defined as the mine and terminal operations and the logistics and wellsite operations. Estimated future undiscounted net cash flows are calculated using estimates, including but not limited to estimates of proven and probable sand reserves, estimated future sales prices (considering historical and current prices, price trends and related factors), operating costs and anticipated capital expenditures. Reductions in the carrying value of our investment are only recorded if the undiscounted cash flows are less than our book basis in the applicable assets. Impairment losses are recognized based on the extent that the remaining investment exceeds the fair value, which is determined based upon the estimated future discounted net cash flows to be generated by the property, plant and equipment and other long-lived assets. Management’s estimates of future sales prices, recoverable proven and probable reserves and operating and capital costs, among other estimates, are subject to certain risks and uncertainties which may affect the recoverability of our investments in property, plant and equipment and other long-lived assets. Although management has made its best estimate of these factors based on current conditions, it is reasonably possible that changes could occur in the near term, which could adversely affect management’s estimate of the net cash flows expected to be generated from its operating assets. During the second quarter of 2019, we saw a significant decrease in the price of our common stock, which resulted in an overall reduction in our market capitalization, and our recorded net book value exceeded our market capitalization as of June 30, 2019. We therefore updated our internal business outlook for the Company to consider the current economic environment that affects our operations. We allocated the enterprise fair value to the reporting units and determined that the fair value of our net assets in the logistics and wellsite operations reporting unit exceeded its carrying value and therefore there was no impairment of long-lived assets in the logistics and wellsite operations reporting unit as of June 30, 2019. Utilizing the allocation of the enterprise fair value to the mine and terminal operations reporting unit, we assessed qualitative factors and determined that we could not conclude that it was more likely than not that the fair value of our net assets exceeded its carrying value. In turn, we prepared a quantitative analysis of the fair value of the mine and terminal operations assets as of June 30, 2019, and determined there is sufficient undiscounted cash flows to recover the value of the long-lived assets although the cushion is not significant. Upon completion of the valuation exercise, it was determined that there was no impairment of long-lived assets as of June 30, 2019. We will reevaluate our long-lived assets in the third quarter of 2019. Leases On January 1, 2019, we adopted Accounting Standards Update ("ASU") 2016-02, Leases (Topic 842) using the modified retrospective transition method, utilizing the simplified transition option available, which allows entities to continue to apply the legacy guidance in ASC 840, Leases , including its disclosure requirements, in the comparative periods presented in the year of adoption. We have elected to apply certain practical expedients, whereby we will not reassess (i) whether any expired or existing contracts are or contain leases, (ii) the lease classification for any expired or existing leases and (iii) initial direct costs for any existing leases. Upon adoption of the new leasing standard on January 1, 2019, we recognized $135,480 of operating lease right-of-use assets, including any lease prepayments made, initial direct costs incurred and excludes lease incentives received, and $127,018 of related operating lease liabilities on the Consolidated Balance Sheet. The impact of adoption of the new leasing standard had no impact to the opening balance of retained earnings on the Consolidated Balance Sheet or to the Consolidated Statements of Operations. Refer to Note 6 - Leases for additional disclosure regarding leases. At inception of a contract, the Company determines if it includes a lease. When a lease is identified, a right-of-use asset and the corresponding lease liability are recorded on the Condensed Consolidated Balance Sheet. Right-of-use assets represent our right to use an underlying asset for the lease term and lease liabilities represent our obligation to make lease payments arising from the lease. Operating lease right-of-use assets and liabilities are recognized at commencement date based on the present value of lease payments over the lease term. As most of our leases do not provide an implicit rate, we use our incremental borrowing rate based on the information available at commencement date in determining the present value of lease payments. The operating lease right-of-use assets also includes any lease prepayments made, initial direct costs incurred and excludes lease incentives received. The operating lease liabilities also includes any deferred rent accrued. We generally do not include renewal or termination options in our assessment of the leases unless extension or termination for certain assets is deemed to be reasonably certain. For all leases with a term of 12 months or less, we elected the practical expedient to not recognize lease assets and liabilities. Lease expense for lease payments is recognized on a straight-line basis over the lease term. Fair Value Measurements The amounts reported in the balance sheet as current assets or liabilities, including cash, accounts receivable, accounts payable, accrued and other current liabilities approximate fair value due to the short-term maturities of these instruments. The Company's financial assets and liabilities are measured using inputs from the three levels of the fair value hierarchy, which are as follows: • Level 1 - observable inputs such as quoted prices in active markets; • Level 2 - inputs other than quoted prices in active markets that we can directly or indirectly observe to the extent that the markets are liquid for the relevant settlement periods; and • Level 3 - unobservable inputs in which little or no market data exists, therefore inputs reflect the Company's assumptions. The fair value of the 9.50% senior unsecured notes due 2026 (the "Senior Notes") approximated $315,000 as of June 30, 2019 , based on the market price quoted from external sources, compared with a carrying value of $450,000 . If the Senior Notes were measured at fair value in the financial statements, it would be classified as Level 2 in the fair value hierarchy. We measure the contingent consideration liability recognized in connection with the acquisition of FB Industries at fair value on a recurring basis using unobservable inputs and it would be classified as Level 3 in the fair value hierarchy. Refer to Note 10 - Commitments and Contingencies for additional disclosure regarding contingent consideration. Income Taxes As a result of the Conversion completed on May 31, 2019, the Company converted from an entity treated as a partnership for U.S. federal income tax purposes to an entity treated as a corporation for U.S. federal income tax purposes and is therefore subject to U.S. federal, state and local corporate income tax. The Conversion resulted in the Company obtaining a partial step-down in the tax basis of certain assets. On the date of the Conversion, we recorded an estimated net tax expense and estimated net deferred tax liability of $115,488 relating to the Conversion as well as this partial step-down in tax basis. Our overall tax provision is based on, among other things, an estimate of the amount of such partial step-down in tax basis that is derived from an analysis of the basis of our unitholders in their ownership of Hi-Crush common units at December 31, 2018 and estimated asset values at the time of the Conversion. While this information does not completely reflect the actual basis of our unitholders at May 31, 2019, our estimate is based on our best estimate of the individual asset valuations and the most recent unitholder basis information available to us. The amount of partial step-down in tax basis cannot be finally determined until complete trading information with respect to common units of the Company for the five months ended May 31, 2019 becomes available. The Company does not currently expect such information to become available until the first quarter of 2020 and the timing and the availability of this information is not within the Company’s control. Since the unitholder basis information currently available to us does not completely reflect the actual basis of our unitholders at May 31, 2019, the amount of partial step-down in tax basis as finally determined is expected to differ, possibly materially, from the current estimate, which in turn is expected to cause the Company’s income tax provision and effective tax rate under GAAP to differ, possibly to a material extent, from the current estimate described herein. If the amount of the partial step-down in tax basis as finally determined is lower than the current estimate, the Company would record a lower net tax expense and an incrementally lower deferred tax liability, which would have the effect of decreasing the amount of taxes payable by the Company in the future. If the amount of partial step-down in tax basis as finally determined is higher than the current estimate, the Company would record a higher net tax expense and an incrementally higher deferred tax liability, which would have the effect of increasing the amount of taxes payable by the Company in the future. Excluding day one deferred taxes related to the Conversion and the Company's pre-tax loss for the five months ended May 31, 2019 prior to the Conversion, the consolidated income for the month of June 2019 and the Canadian operations income for the five months ended May 31, 2019 were subject to corporate tax at an estimated effective tax rate of approximately 20% . As such, the effective tax rate differs from the statutory rate primarily due to the following: (i) the tax expense recognized as a result of the partial step-down in tax basis of certain assets as a result of the Conversion as described above, (ii) the tax expense recognized that relates to the post-conversion book income, (iii) state income taxes, (iv) the impact of current year acquisitions, (v) certain compensation charges attributable to the Company that are not deductible for tax purposes, and (vi) certain book expenses that are not deductible for tax purposes. Prior to the Conversion, the Company was a pass-through entity and was not considered a taxable entity for federal tax purposes. Therefore, there is not a provision for income taxes for U.S. federal or certain other state jurisdictions in the accompanying Condensed Consolidated Financial Statements prior to May 31, 2019. Deferred Income Taxes Income taxes are accounted for using the asset and liability method of accounting. Under this method, deferred tax assets and liabilities are recognized for the expected future tax consequences of differences between the carrying amounts of assets and liabilities and their respective tax basis, using tax rates in effect for the year in which the differences are expected to reverse. The effect on deferred assets and liabilities of a change in tax rates is recognized in the Condensed Consolidated Statements of Operations in the period when the change is enacted. Deferred tax assets are reduced by a valuation allowance when, based on the weight of available evidence, it is more likely than not that some portion or all of the deferred tax assets will not be realized. When evaluating the realizability of the deferred tax assets, all evidence, both positive and negative, is considered. Items considered when evaluating the need for a valuation allowance include the ability to carry back losses, future reversals of existing temporary differences, tax planning strategies, and expectations of future earnings. For a particular tax‑paying component of an entity and within a particular tax jurisdiction, deferred tax assets and liabilities are offset and presented as a single amount, as applicable, in the accompanying statements of financial condition. Foreign Currency Translation The Company records foreign currency translation adjustments from the process of translating the functional currency of the financial statements of its foreign subsidiary into the U.S. dollar reporting currency. The Canadian dollar is the functional currency of the Company's foreign subsidiary as it is the primary currency within the economic environment in which the subsidiary operates. Assets and liabilities of the subsidiary's operations are translated into U.S. dollars at the rate of exchange in effect on the balance sheet date and income and expenses are translated at the average exchange rate in effect during the reporting period. Adjustments resulting from the translation of the subsidiary's financial statements are reported in other comprehensive income.

The Company previously held a 66% ownership interest in Proppant Logistics, which was accounted for using the equity method. We remeasured our previously held equity interest in Proppant Logistics at fair value as of the date we obtained control in accordance with the accounting guidance for acquisitions achieved in stages in ASC 805, Business Combinations . As a result, we recognized a gain of $3,612 on the remeasurement of our equity method investment during the second quarter of 2019. The preliminary purchase price of $16,045 was allocated to the net assets acquired as follows: Net assets of Proppant Logistics as of May 7, 2019: Cash $ 1,841 Accounts receivable 7,951 Prepaid expenses and other current assets 782 Property, plant and equipment 205 Other assets 247 Goodwill and intangible assets 15,662 Accounts payable (7,047 ) Accrued and other current liabilities (359 ) Credit facility (3,237 ) Fair value of net assets acquired $ 16,045 The excess of the purchase consideration over the fair value of net assets acquired was recorded as goodwill. The recognition of goodwill is attributable to strategic benefits and expected synergies of our combined operations.

Prior periods presented have not been adjusted and continue to be reported in accordance with the legacy guidance in Topic 840. Lessee The Company has long-term operating leases, comprised primarily of railcars and container lease arrangements, equipment, office space and terminals. Our operating leases have remaining lease terms of 1.1 years to 9.1 years , some of which include automatic renewal options, options to extend the leases and options to terminate the leases. As of June 30, 2019 , the balance sheet information related to leases are as follows: Operating lease right-of-use assets $ 128,211 Current portion of operating lease liabilities $ 38,565 Operating lease liabilities 82,667 Total operating lease liabilities $ 121,232 Operating lease liabilities are based on the net present value of the remaining lease payments over the remaining lease term. In determining the lease liability and the present value of lease payments, we used our incremental borrowing rate based on the information available at the lease commencement date. The weighted average remaining lease term and discount rate as of June 30, 2019 related to operating leases are as follows: Weighted average remaining lease term 4.9 years Weighted average discount rate 9.50 % The components of operating lease expenses on our Condensed Consolidated Statement of Operations for the three and six months ended June 30, 2019 is as follows: Three Months Ended Six Months Ended June 30, 2019 June 30, 2019 Cost of goods sold Operating lease cost $ 10,189 $ 20,126 Short-term lease cost 1,454 2,814 $ 11,643 $ 22,940 General and administrative expenses Operating lease cost $ 65 $ 129 Short-term lease cost 124 278 $ 189 $ 407 Total lease costs $ 11,832 $ 23,347 Supplemental cash flow information related to our operating leases for the three and six months ended June 30, 2019 is as follows: Three Months Ended Six Months Ended June 30, 2019 June 30, 2019 Cash paid for amounts included in the measurement of lease liabilities $ 12,992 $ 25,575 Noncash information on lease liabilities arising from obtaining right-of-use assets $ 6,974 $ 142,454 As of June 30, 2019 , the maturities of operating lease liabilities are as follows: Fiscal Year 2019 (remaining months) $ 20,379 2020 40,107 2021 31,931 2022 21,918 2023 10,826 Thereafter 25,996 Total lease payments 151,157 Less: present value adjustment (29,925 ) Total operating lease liabilities $ 121,232 As of December 31, 2018, future minimum operating lease payments are as follows: Fiscal Year 2019 $ 36,019 2020 36,282 2021 29,272 2022 20,890 2023 10,280 Thereafter 31,066 $ 163,809 Lessor

Goodwill represents the excess purchase over the fair value of net assets acquired in the acquisitions of FB Industries and Proppant Logistics and is allocated to the logistics and wellsite operations reporting unit. We perform our annual assessment of the recoverability of goodwill during the third quarter of each fiscal year, or more often if events or circumstances indicate the impairment of an asset may exist. During the second quarter of 2019, we saw a significant decrease in the price of our common stock, which resulted in an overall reduction in our market capitalization, and our market capitalization exceeded our recorded net book value as of June 30, 2019. We therefore updated our internal business outlook for the Company, including the logistics and wellsite operations reporting unit, to consider the current economic environment that affects our operations. As a result, we assessed quantitative factors and determined that the fair value of goodwill exceeded its carrying value and therefore there was no impairment of goodwill as of June 30, 2019.

The promissory notes accrue interest at rates equal to the applicable short-term federal rates. All principal and accrued interest is due and payable at the end of the respective three-year promissory note terms. However, the promissory notes are prepaid on a quarterly basis during the three-year terms as sand is extracted, delivered, sold and paid for from the properties. The Company made prepayments of $691 and $968 during the three months ended June 30, 2019 and 2018 , respectively, and $1,385 and $1,925 during the six months ended June 30, 2019 and 2018 , respectively, based on the accumulated volume of sand extracted, delivered, sold and paid for.

Commitments and Contingencies	Commitments and Contingencies Customer Contracts The Company enters into sales contracts with customers. These contracts establish minimum annual sand volumes that the Company is required to make available to such customers under initial terms ranging from one to seven years. Through June 30, 2019 , no payments for non-delivery of minimum annual sand volumes have been made by the Company to customers under these contracts. Royalty Agreements The Company has entered into royalty agreements under which it is committed to pay royalties on sand sold from its production facilities for which the Company has received payment by the customer. Royalty expense is recorded as the sand is sold and is included in costs of goods sold. Royalty expense was $2,239 and $5,078 for the three months ended June 30, 2019 and 2018 , respectively, and $3,710 and $8,618 for the six months ended June 30, 2019 and 2018 , respectively. Certain acreage is subject to a minimum annual royalty payment. If not paid within 30 days after the annual period, the original landowner has the right to purchase the property for one dollar, subject to certain terms. If we have not made the minimum required royalty payments, we may satisfy our obligation by making a lump-sum cash make-whole payment. Accordingly, we believe there is no material risk that we will be required to sell back the subject property pursuant to this agreement. Property Value Guarantees The Company entered into mining agreements and land use agreements with the Wisconsin municipalities of Bridge Creek, Lincoln, Springfield and Preston that contain property value guarantees ("PVG") for certain property owners in proximity to each mine. The respective PVGs establish a process whereby we guaranty fair market value to the owners of residential property specifically identified within the body of the PVG document. According to the terms of the PVGs, the property owner must notify us in the event they wish to sell the subject residence and additional acreage in certain instances. Upon such notice, the PVGs establish a process by which an appraisal is conducted and the subject property is appraised to establish fair market value and is listed with a real estate broker. In the event the property is sold within 180 days of listing, we agree to pay the owner any shortfall between the sales price and the established fair market value. In the event the property is not sold within the 180 days time frame, we are obligated to purchase the property for fair market value. As of June 30, 2019 , we have not accrued a liability related to the PVGs because it is not possible to estimate how many of the owners will elect to avail themselves of the provisions of the PVGs and it cannot be determined if shortfalls will exist in the event of a sale nor can the value of the subject property be ascertained until appraised. As of June 30, 2019 , the Company has paid $3,085 under these guarantees since inception. Purchase Commitments We have entered into service agreements with certain transload service providers which requires us to purchase minimum amounts of services over specific periods of time at specific locations. Our failure to purchase the minimum level of services would require us to pay shortfall fees. As of June 30, 2019 , future minimum purchase commitments are as follows: Fiscal Year 2019 (remaining months) $ 2,475 2020 2,377 2021 2,344 2022 2,344 2023 2,182 Thereafter 677 $ 12,399 Contingent Consideration In connection with the acquisition of FB Industries, the agreement contained certain contingent consideration arrangements from the date of closing to December 31, 2021, dependent upon leases or sales of certain silo equipment to be paid quarterly. As of June 30, 2019 , the total estimated fair value of the contingent consideration is $7,755 and is recorded in accrued and other current liabilities and other liabilities on the Condensed Consolidated Balance Sheet. The current portion of the contingent consideration is $300 and relates to the sale of silo equipment. Changes in fair value of the contingent consideration, for facts and circumstances that existed at the time of the acquisition, prior to finalizing the purchase price allocation are accounted for as an adjustment to goodwill. Subsequent changes in fair value of the contingent consideration after the measurement period are recognized in earnings in the period identified. The estimated fair value assumes primarily leases are entered into during this period with minimal sales of silo equipment. A 10% increase or decrease in the assumed quantity of leases would result in an increase to $9,818 or a decrease to $5,913 , respectively, in the fair value of the contingent consideration. Conversely, a 50% shift in the assumed quantity of leases to sales of silo systems and conveyors would reduce the contingent consideration to $2,731 . The following table provides a summary of changes in the fair value of the contingent consideration: Balance at December 31, 2018 $ 8,147 Changes in estimated fair value of contingent consideration liability (392 ) Balance at June 30, 2019 $ 7,755 Litigation From time to time the Company may be subject to various claims and legal proceedings which arise in the normal course of business. Management is not aware of any legal matters that are likely to have a material adverse effect on the Company’s financial position, results of operations or cash flows.

Equity [Abstract]
Equity	Equity On May 31, 2019, at the effective time of the Conversion, the outstanding common units were each exchanged for one issued and outstanding share of common stock. Holders of common units immediately prior to the Conversion collectively received, in exchange for their common units, 100% of the shares of common stock issued and outstanding immediately following the Conversion. As of the open of business on June 3, 2019, the common stock commenced trading on the NYSE under the ticker symbol "HCR." Under the certificate of incorporation of the Company that was entered into at the effective time of Conversion, the Company has authority to issue a total of 600,000,000 shares, of which 500,000,000 are designated as common stock, par value $0.01 per share and 100,000,000 are designated as preferred stock, par value $0.01 per share. Equity Issuances On May 7, 2019, the Company issued 695,606 common units as additional consideration for the Proppant Logistics acquisition. Stock Repurchase Program On June 8, 2019, the Company's board of directors approved a new stock repurchase program of up to $25,000 , effective immediately and authorized through June 30, 2020. The new stock repurchase program superseded our previous unit buyback program, which was terminated upon the Conversion on May 31, 2019. The stock repurchase program does not obligate the Company to repurchase any specific dollar amount or number of shares and may be suspended, modified or discontinued by the board of directors at any time, in its sole discretion and without notice. The following table presents information with respect to repurchases of common shares made by the Company during the periods presented, which were retired upon repurchase: Three Months Ended Six Months Ended June 30, June 30, 2019 2018 2019 2018 Number of shares purchased 1,177,731 — 1,177,731 753,090 Average price paid per share including commission $ 2.67 $ — $ 2.67 $ 12.52 Total cost $ 3,151 $ — $ 3,151 $ 9,426 As of June 30, 2019 , the Company has repurchased a total of 1,177,731 common shares under the new stock repurchase program for a total cost of $3,151 , with $21,849 remaining under its approved stock repurchase program. Equity Distribution Agreement On January 4, 2017, the Company entered into an equity distribution program with certain financial institutions (each, a "Manager") under which we were permitted to sell, from time to time, through or to the Managers, common units up to an aggregate gross sales price of $50,000 . Upon the Conversion on May 31, 2019, the equity distribution agreement was terminated. The Company did not issue any common units pursuant to the equity distribution program. Allocations of Net Income Prior to the Sponsor Contribution, the partnership agreement that governed Hi-Crush prior to the Conversion (the "partnership agreement") contained provisions for the allocation of net income and loss to the unitholders and the general partner. For purposes of maintaining partner capital accounts, the partnership agreement specified that items of income and loss shall be allocated among the partners in accordance with their respective percentage ownership interest. Normal allocations according to percentage interests were made after giving effect, if any, to priority income allocations in an amount equal to incentive cash distributions allocated 100% to the sponsor for the periods applicable prior to the Sponsor Contribution. Upon the Conversion on May 31, 2019, the partnership agreement was terminated. During the three and six months ended June 30, 2018 , prior to the Sponsor Contribution, no income was allocated to the holder of our incentive distribution rights. Distributions, Incentive Distribution Rights and Dividends Prior to the Conversion, the partnership agreement set forth the calculation to be used to determine the amount of cash distributions that our limited partner unitholders and the holder of our incentive distribution rights received prior to the Sponsor Contribution. The incentive distribution rights were held by the sponsor and were canceled and extinguished on October 21, 2018 in connection with the Sponsor Contribution. Upon the Conversion on May 31, 2019, the partnership agreement was terminated. On January 7, 2019 , we announced the decision of the board of directors to suspend the quarterly distribution to common unitholders. The Company has not yet adopted a policy regarding payment of dividends. Dividends may be declared from time to time by the board of directors out of funds legally available for dividend payments. Any dividend policy adopted may be amended, revoked or suspended at any time, and while any dividend policy is in place, the actual amount of dividends on the common stock will depend on many factors, including the Company’s financial condition and results of operations, liquidity requirements, market opportunities, capital requirements, legal, regulatory and contractual constraints, tax laws and other factors. Our most recent distributions, prior to the Conversion, were as follows: Declaration Date Amount Declared Per Unit Record Date Payment Date Payment to Limited Partner Units Payment to the Holder of Incentive Distribution Rights January 17, 2018 $ 0.2000 February 1, 2018 February 13, 2018 $ 17,809 $ — April 18, 2018 $ 0.2250 May 1, 2018 May 15, 2018 $ 19,888 $ — July 20, 2018 $ 0.7500 August 3, 2018 August 14, 2018 $ 67,253 $ 7,664 October 21, 2018 $ 0.2250 November 1, 2018 November 14, 2018 $ 22,695 $ — Recast Equity Transactions During the three and six months ended June 30, 2018 , the sponsor paid cash distributions of $662 and $25,500 to its members. Such transactions are reflected within the non-controlling interest section of the Consolidated Statement of Partners' Capital.

Earnings Per Share [Abstract]
Earnings Per Share	Earnings Per Share Basic earnings per share of common stock is computed by dividing net income or loss by the weighted average number of shares of common stock outstanding during the period. Diluted earnings per share of common stock is computed by dividing the net income or loss by the sum of the weighted average number of shares of common stock outstanding during the period, plus the potential dilutive effects of stock awards outstanding during the period calculated in accordance with the treasury stock method. Diluted earnings per share excludes any dilutive stock awards granted (see Note 13 - Stock-Based Compensation ) if their effect is anti-dilutive. During the three and six months ended June 30, 2019 , the Company incurred a net loss and, as a result, all 2,512,258 stock awards granted and outstanding were excluded from the diluted earnings per share calculation. Diluted earnings per unit for the three and six months ended June 30, 2018 includes the dilutive effect of all 1,337,249 stock awards, granted and outstanding at the assumed number of shares which would have vested if the performance period had ended on June 30, 2018 . The following tables provide a reconciliation of net loss and the basic and diluted, weighted average common shares outstanding for purposes of computing loss per share for the three and six months ended June 30, 2019 : Three Months Ended Six Months Ended June 30, 2019 June 30, 2019 Net loss $ (117,484 ) $ (123,691 ) Basic weighted average common shares outstanding 101,312,754 101,165,914 Potentially dilutive common shares — — Diluted weighted average common shares outstanding 101,312,754 101,165,914 Loss per share - basic $ (1.16 ) $ (1.22 ) Loss per share - diluted $ (1.16 ) $ (1.22 ) Prior to the Sponsor Contribution, for purposes of calculating the Company’s earnings per unit under the two-class method, common units were treated as participating preferred units and the incentive distribution rights were treated as participating securities. Each period, the Company determined the amount of cash available for distributions in accordance with the partnership agreement. The amount to be distributed to limited partner unitholders and incentive distribution rights holder was subject to the distribution waterfall in the partnership agreement for the periods applicable prior to the Sponsor Contribution. Net earnings or loss for the period were allocated to each class of partnership interest based on the distributions to be made. As described in Note 1 , the Company's historical financial information has been recast to combine the sponsor and general partner for all periods presented. The amounts of incremental losses recast to periods prior to the Sponsor Contribution were excluded from the calculation of earnings per limited partner unit. The following tables provide a reconciliation of net income, the assumed allocation of net income and the basic and diluted, weighted average limited partner units outstanding under the two-class method for purposes of computing earnings per limited partner unit for the three and six months ended June 30, 2018 : Three Months Ended June 30, 2018 General Partner and IDRs Limited Partner Units Total Declared distribution $ 7,554 $ 66,294 $ 73,848 Assumed allocation of distribution in excess of earnings — (6,892 ) (6,892 ) Add back recast losses attributable to the sponsor and general partner — 1,052 1,052 Assumed allocation of net income $ 7,554 $ 60,454 $ 68,008 Basic weighted average common units outstanding 88,392,179 Potentially dilutive common units 1,337,249 Diluted weighted average common units outstanding 89,729,428 Earnings per limited partner unit - basic $ 0.68 Earnings per limited partner unit - diluted $ 0.67 Six Months Ended June 30, 2018 General Partner and IDRs Limited Partner Units Total Declared distribution $ 7,554 $ 86,182 $ 93,736 Assumed allocation of earnings in excess of distributions (2,262 ) 28,913 26,651 Add back recast losses attributable to the sponsor and general partner — 1,570 1,570 Assumed allocation of net income $ 5,292 $ 116,665 $ 121,957 Basic weighted average common units outstanding 88,629,958 Potentially dilutive common units 1,337,249 Diluted weighted average common units outstanding 89,967,207 Earnings per limited partner unit - basic $ 1.32 Earnings per limited partner unit - diluted $ 1.30

Disclosure of Compensation Related Costs, Share-based Payments [Abstract]
Stock-Based Compensation	Stock-Based Compensation Hi-Crush Inc. Long Term Incentive Plan On May 31, 2019, in connection with the Conversion, the board of directors approved the Hi-Crush Inc. Long Term Incentive Plan (the "Plan") for the benefit of employees, directors and other service providers of the Company and its affiliates. The Plan provides for the grant of stock options, stock appreciation rights, restricted stock, restricted stock units, stock awards, dividend equivalents, other stock-based awards, cash awards and substitute awards. The Plan has 8,731,053 shares of common stock reserved for issuance pursuant to awards under the Plan, which includes shares allocable to the phantom unit awards that were outstanding under the Hi-Crush Partners LP First Amended and Restated Long-Term Incentive Plan (the "HCLP Plan") and were converted into awards of Performance Share Units ("PSUs") and Restricted Stock Units ("RSUs"), as applicable, under the Plan, effective at the time of the Conversion. The Plan is administered by the board of directors or a committee thereof. The HCLP Plan was terminated effective at the time of the Conversion, and all units previously registered by the Company with respect to that plan have been deregistered with the SEC. Performance Share Units Pursuant to the Plan, the Company awards PSUs to certain employees. The Company previously awarded performance phantom units under the HCLP Plan to certain employees, which were converted into PSUs under the Plan in connection with the Conversion. The number of PSUs that will vest will range from 0% to 200% of the number of initially granted PSUs and is dependent on the Company's total shareholder return over a three -year performance period compared to the total shareholder return of a designated peer group. Each PSU represents the right to receive, upon vesting, one share of common stock in the Company. The PSUs are also entitled to forfeitable dividend equivalent rights ("DERs"), which accumulate during the performance period and are paid in cash on the date of settlement. The fair value of each PSU is estimated using a fair value approach and is amortized into compensation expense, reduced for an estimate of expected forfeitures, over the period of service corresponding with the vesting period. Expected volatility is based on the historical market performance of our peer group. The following table presents information relative to our PSUs: Units Grant Date Weighted-Average Fair Value per Unit Outstanding at December 31, 2018 747,920 $ 5.93 Vested (97,865 ) $ 16.01 Forfeited (82,801 ) $ 4.44 Outstanding at June 30, 2019 567,254 $ 4.31 As of June 30, 2019 , total compensation expense not yet recognized related to unvested PSUs was $1,586 , with a weighted average remaining service period of 1.9 years . Restricted Stock Units Pursuant to the Plan, the Company awards RSUs to certain employees which automatically vest if the employee remains employed at the end of the vesting period. The Company previously awarded time-based phantom units under the HCLP Plan to certain employees, which were converted into RSUs under the Plan in connection with the Conversion. Vesting generally occurs over a three -year period subject to either cliff or graded vesting. Each RSU represents the right to receive, upon vesting, one share of common stock in the Company. The RSUs are also entitled to forfeitable DERs, which accumulate during the vesting period and are paid in cash on the date of settlement. The fair value of each RSU is calculated based on the grant-date stock price and is amortized into compensation expense, reduced for an estimate of expected forfeitures, over the period of service corresponding with the vesting period. The following table presents information relative to our RSUs: Units Grant Date Weighted-Average Fair Value per Unit Outstanding at December 31, 2018 1,642,218 $ 8.07 Vested (80,345 ) $ 9.73 Granted 538,968 $ 3.08 Forfeited (155,837 ) $ 5.37 Outstanding at June 30, 2019 1,945,004 $ 6.56 As of June 30, 2019 , total compensation expense not yet recognized related to unvested RSUs was $7,153 , with a weighted average remaining service period of 2.0 years . Director Stock Grants The Company issued 62,184 and 36,109 shares of common stock to certain of its directors during the six months ended June 30, 2019 and 2018 , respectively. Unit Purchase Program The Company maintained the Second 2017 Unit Purchase Program (the "Second 2017 UPP"), which provided participating employees and members of our general partner's board of directors the opportunity to purchase common units of the Company at a discount. On September 14, 2017, the offering period under the Second 2017 UPP commenced, with a 15% discount of the fair value of our common units on the applicable election date and a purchase date of November 15, 2018 . On September 14, 2017, the Company calculated the fair value of the discount, which was recognized as unit compensation expense on a straight-line basis during the offering period. The offering period under the Second 2017 UPP ended on November 15, 2018, at which time the purchase date price was less than the Election Price. As a result, all contributions were returned to the participants and no common units were purchased under the Second 2017 UPP. Compensation Expense The following table presents total stock-based compensation expense: Three Months Ended Six Months Ended June 30, June 30, 2019 2018 2019 2018 Performance Share Units $ 277 $ 342 $ 536 $ 685 Restricted Stock Units 1,566 1,250 2,823 2,489 Director stock grants 61 118 123 237 Unit Purchase Program — 100 — 200 Total compensation expense $ 1,904 $ 1,810 $ 3,482 $ 3,611

Revenue from Contract with Customer [Abstract]
Revenues	Revenues The Company recognizes revenue at the point in time control of the promised goods or services is transferred to our customers, in an amount that reflects the consideration we expect to be entitled to in exchange for those goods or services. A performance obligation is a promise in a contract to transfer a distinct good or service to the customer, and is the unit of account. A contract's transaction price is allocated to each distinct performance obligation and recognized as revenue when, or as, the performance obligation is satisfied. The majority of our contracts are frac sand contracts that have a single performance obligation as the promise to transfer individual goods or services is not separately identifiable from other promises in the contracts and, therefore, not distinct. For the portion of our contracts that contain multiple performance obligations, such as work orders containing a combination of product, transportation, equipment rentals, and labor services, we allocate the transaction price to each performance obligation identified in the contract based on relative stand-alone selling prices, or estimates of such prices, and recognize the related revenue as control of each individual product or service is transferred to the customer, in satisfaction of the corresponding performance obligations. Disaggregation of Revenues The following table presents our revenues disaggregated by contractual relationships: Three Months Ended Six Months Ended June 30, June 30, 2019 2018 2019 2018 Sales to contract customers $ 87,226 $ 186,946 $ 167,290 $ 351,013 Spot sales 38,658 25,757 73,685 53,174 Frac sand sales revenues 125,884 212,703 240,975 404,187 Other revenues 52,117 35,817 96,936 62,446 Total revenues $ 178,001 $ 248,520 $ 337,911 $ 466,633 Practical Expedients and Exemptions We have elected to use the practical expedients, pursuant to which we have excluded disclosures of transaction prices allocated to remaining performance obligations and when we expect to recognize such revenue. We have various long-term contracts with minimum purchase and supply requirements with terms expiring between 2019 and 2024 . The remaining performance obligations are primarily comprised of unfulfilled product, transportation service, and labor service orders, some of which hold a remaining duration of less than one year. Our transaction price for volumes and services under these contracts is based on timing of customer orders, points of sale, mix of products sold, impact of market conditions and potential contract negotiations, which have not yet been determined and therefore the price is variable in nature. The long term portion of deferred revenue represents customer prepayments for which related current performance obligations do not yet exist, but are expected to arise, before the expiration of the term. Deferred Revenues As of June 30, 2019 , the Company has recorded a total liability of $31,907 for prepayments of future deliveries of frac sand and silo equipment. Some prepayments are refundable in the event that the Company is unable to meet the minimum requirements under certain contracts. We expect to recognize these revenues over the next 1.2 years . The following table reflects the changes in our contract liabilities, which we classify as deferred revenues: Balance at December 31, 2018 $ 29,785 Collection of prepayments 8,750 Revenues recognized (6,772 ) Customer prepayments acquired in business acquisitions 90 Impact of foreign currency translation 54 Balance at June 30, 2019 $ 31,907

Significant Accounting Policies (Policies)	6 Months Ended

Accounting Policies [Abstract]
Use of Estimates	Use of Estimates The preparation of the financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amount of assets and liabilities and disclosure of contingent liabilities at the date of the financial statements and the reported amount of revenues and expenses during the reporting period. Actual results could differ from those estimates.
Accounts Receivable	Accounts Receivable Trade receivables relate to sales of frac sand, related services and the sale of logistics equipment for which credit is extended based on the customer’s credit history and are recorded at the invoiced amount and do not bear interest. The Company regularly reviews the collectability of accounts receivable. When it is probable that all or part of an outstanding balance will not be collected, the Company establishes or adjusts an allowance as necessary, generally using the specific identification method. Account balances are charged against the allowance after all means of collection have been exhausted and potential recovery is considered remote. As of each of June 30, 2019 and December 31, 2018 , the Company maintained an allowance for doubtful accounts of $1,060 .
Impairment of Long-Lived Assets	Impairment of Long-lived Assets Recoverability of investments in property, plant and equipment, and other long-lived assets is evaluated annually, or more often if events or circumstances indicate the impairment of an asset may exist, based on reporting units, which management has defined as the mine and terminal operations and the logistics and wellsite operations. Estimated future undiscounted net cash flows are calculated using estimates, including but not limited to estimates of proven and probable sand reserves, estimated future sales prices (considering historical and current prices, price trends and related factors), operating costs and anticipated capital expenditures. Reductions in the carrying value of our investment are only recorded if the undiscounted cash flows are less than our book basis in the applicable assets. Impairment losses are recognized based on the extent that the remaining investment exceeds the fair value, which is determined based upon the estimated future discounted net cash flows to be generated by the property, plant and equipment and other long-lived assets. Management’s estimates of future sales prices, recoverable proven and probable reserves and operating and capital costs, among other estimates, are subject to certain risks and uncertainties which may affect the recoverability of our investments in property, plant and equipment and other long-lived assets. Although management has made its best estimate of these factors based on current conditions, it is reasonably possible that changes could occur in the near term, which could adversely affect management’s estimate of the net cash flows expected to be generated from its operating assets.
Leases	Leases On January 1, 2019, we adopted Accounting Standards Update ("ASU") 2016-02, Leases (Topic 842) using the modified retrospective transition method, utilizing the simplified transition option available, which allows entities to continue to apply the legacy guidance in ASC 840, Leases , including its disclosure requirements, in the comparative periods presented in the year of adoption. We have elected to apply certain practical expedients, whereby we will not reassess (i) whether any expired or existing contracts are or contain leases, (ii) the lease classification for any expired or existing leases and (iii) initial direct costs for any existing leases. Upon adoption of the new leasing standard on January 1, 2019, we recognized $135,480 of operating lease right-of-use assets, including any lease prepayments made, initial direct costs incurred and excludes lease incentives received, and $127,018 of related operating lease liabilities on the Consolidated Balance Sheet. The impact of adoption of the new leasing standard had no impact to the opening balance of retained earnings on the Consolidated Balance Sheet or to the Consolidated Statements of Operations. Refer to Note 6 - Leases for additional disclosure regarding leases. At inception of a contract, the Company determines if it includes a lease. When a lease is identified, a right-of-use asset and the corresponding lease liability are recorded on the Condensed Consolidated Balance Sheet. Right-of-use assets represent our right to use an underlying asset for the lease term and lease liabilities represent our obligation to make lease payments arising from the lease. Operating lease right-of-use assets and liabilities are recognized at commencement date based on the present value of lease payments over the lease term. As most of our leases do not provide an implicit rate, we use our incremental borrowing rate based on the information available at commencement date in determining the present value of lease payments. The operating lease right-of-use assets also includes any lease prepayments made, initial direct costs incurred and excludes lease incentives received. The operating lease liabilities also includes any deferred rent accrued. We generally do not include renewal or termination options in our assessment of the leases unless extension or termination for certain assets is deemed to be reasonably certain. For all leases with a term of 12 months or less, we elected the practical expedient to not recognize lease assets and liabilities. Lease expense for lease payments is recognized on a straight-line basis over the lease term.
Fair Value Measurements	Fair Value Measurements The amounts reported in the balance sheet as current assets or liabilities, including cash, accounts receivable, accounts payable, accrued and other current liabilities approximate fair value due to the short-term maturities of these instruments. The Company's financial assets and liabilities are measured using inputs from the three levels of the fair value hierarchy, which are as follows: • Level 1 - observable inputs such as quoted prices in active markets; • Level 2 - inputs other than quoted prices in active markets that we can directly or indirectly observe to the extent that the markets are liquid for the relevant settlement periods; and • Level 3 - unobservable inputs in which little or no market data exists, therefore inputs reflect the Company's assumptions. The fair value of the 9.50% senior unsecured notes due 2026 (the "Senior Notes") approximated $315,000 as of June 30, 2019 , based on the market price quoted from external sources, compared with a carrying value of $450,000 . If the Senior Notes were measured at fair value in the financial statements, it would be classified as Level 2 in the fair value hierarchy. We measure the contingent consideration liability recognized in connection with the acquisition of FB Industries at fair value on a recurring basis using unobservable inputs and it would be classified as Level 3 in the fair value hierarchy. Refer to Note 10 - Commitments and Contingencies for additional disclosure regarding contingent consideration.
Income Taxes	Income Taxes As a result of the Conversion completed on May 31, 2019, the Company converted from an entity treated as a partnership for U.S. federal income tax purposes to an entity treated as a corporation for U.S. federal income tax purposes and is therefore subject to U.S. federal, state and local corporate income tax. The Conversion resulted in the Company obtaining a partial step-down in the tax basis of certain assets. On the date of the Conversion, we recorded an estimated net tax expense and estimated net deferred tax liability of $115,488 relating to the Conversion as well as this partial step-down in tax basis. Our overall tax provision is based on, among other things, an estimate of the amount of such partial step-down in tax basis that is derived from an analysis of the basis of our unitholders in their ownership of Hi-Crush common units at December 31, 2018 and estimated asset values at the time of the Conversion. While this information does not completely reflect the actual basis of our unitholders at May 31, 2019, our estimate is based on our best estimate of the individual asset valuations and the most recent unitholder basis information available to us. The amount of partial step-down in tax basis cannot be finally determined until complete trading information with respect to common units of the Company for the five months ended May 31, 2019 becomes available. The Company does not currently expect such information to become available until the first quarter of 2020 and the timing and the availability of this information is not within the Company’s control. Since the unitholder basis information currently available to us does not completely reflect the actual basis of our unitholders at May 31, 2019, the amount of partial step-down in tax basis as finally determined is expected to differ, possibly materially, from the current estimate, which in turn is expected to cause the Company’s income tax provision and effective tax rate under GAAP to differ, possibly to a material extent, from the current estimate described herein. If the amount of the partial step-down in tax basis as finally determined is lower than the current estimate, the Company would record a lower net tax expense and an incrementally lower deferred tax liability, which would have the effect of decreasing the amount of taxes payable by the Company in the future. If the amount of partial step-down in tax basis as finally determined is higher than the current estimate, the Company would record a higher net tax expense and an incrementally higher deferred tax liability, which would have the effect of increasing the amount of taxes payable by the Company in the future. Excluding day one deferred taxes related to the Conversion and the Company's pre-tax loss for the five months ended May 31, 2019 prior to the Conversion, the consolidated income for the month of June 2019 and the Canadian operations income for the five months ended May 31, 2019 were subject to corporate tax at an estimated effective tax rate of approximately 20% . As such, the effective tax rate differs from the statutory rate primarily due to the following: (i) the tax expense recognized as a result of the partial step-down in tax basis of certain assets as a result of the Conversion as described above, (ii) the tax expense recognized that relates to the post-conversion book income, (iii) state income taxes, (iv) the impact of current year acquisitions, (v) certain compensation charges attributable to the Company that are not deductible for tax purposes, and (vi) certain book expenses that are not deductible for tax purposes. Prior to the Conversion, the Company was a pass-through entity and was not considered a taxable entity for federal tax purposes. Therefore, there is not a provision for income taxes for U.S. federal or certain other state jurisdictions in the accompanying Condensed Consolidated Financial Statements prior to May 31, 2019. Deferred Income Taxes Income taxes are accounted for using the asset and liability method of accounting. Under this method, deferred tax assets and liabilities are recognized for the expected future tax consequences of differences between the carrying amounts of assets and liabilities and their respective tax basis, using tax rates in effect for the year in which the differences are expected to reverse. The effect on deferred assets and liabilities of a change in tax rates is recognized in the Condensed Consolidated Statements of Operations in the period when the change is enacted. Deferred tax assets are reduced by a valuation allowance when, based on the weight of available evidence, it is more likely than not that some portion or all of the deferred tax assets will not be realized. When evaluating the realizability of the deferred tax assets, all evidence, both positive and negative, is considered. Items considered when evaluating the need for a valuation allowance include the ability to carry back losses, future reversals of existing temporary differences, tax planning strategies, and expectations of future earnings. For a particular tax‑paying component of an entity and within a particular tax jurisdiction, deferred tax assets and liabilities are offset and presented as a single amount, as applicable, in the accompanying statements of financial condition.
Foreign Currency Translation	Foreign Currency Translation The Company records foreign currency translation adjustments from the process of translating the functional currency of the financial statements of its foreign subsidiary into the U.S. dollar reporting currency. The Canadian dollar is the functional currency of the Company's foreign subsidiary as it is the primary currency within the economic environment in which the subsidiary operates. Assets and liabilities of the subsidiary's operations are translated into U.S. dollars at the rate of exchange in effect on the balance sheet date and income and expenses are translated at the average exchange rate in effect during the reporting period. Adjustments resulting from the translation of the subsidiary's financial statements are reported in other comprehensive income.
