Organization, Consolidation and Presentation of Financial Statements [Abstract]
BASIS OF PRESENTATION	BASIS OF PRESENTATION The accompanying unaudited condensed consolidated financial statements include the accounts of U.S. Concrete, Inc. and its subsidiaries (collectively, "we," "us," "our," "U.S. Concrete," or the "Company") and have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission (the "SEC") for reporting interim financial information. Some information and footnote disclosures normally included in financial statements prepared in accordance with generally accepted accounting principles in the United States ("U.S. GAAP") have been condensed or omitted pursuant to the SEC’s rules and regulations. These unaudited condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements and related notes in our Annual Report on Form 10-K for the year ended December 31, 2016 (the " 2016 Form 10-K"). In the opinion of our management, all adjustments necessary to state fairly the information in our unaudited condensed consolidated financial statements and to make such financial statements not misleading have been included. All adjustments are of a normal or recurring nature. Operating results for the three months ended March 31, 2017 are not necessarily indicative of our results expected for the year ending December 31, 2017 , or for any future period. The preparation of financial statements and accompanying notes in conformity with U.S. GAAP requires management to make estimates and assumptions in determining the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities as of the date of the financial statements and the reported amounts of revenue and expenses during the reporting period. Actual results could differ from those estimates. Estimates and assumptions that we consider critical and that involve complex judgments in the preparation of our financial statements include those related to our business combinations, goodwill and goodwill impairment, impairment of long-lived assets, accruals for self-insurance programs, income taxes, derivative instruments, and contingent consideration. Certain reclassifications have been made to prior year balances to conform with the current year presentation.

Accounting Changes and Error Corrections [Abstract]
RECENT ACCOUNTING PRONOUNCEMENTS AND SIGNIFICANT ACCOUNTING POLICIES	RECENT ACCOUNTING PRONOUNCEMENTS AND SIGNIFICANT ACCOUNTING POLICIES Amendments Adopted This Quarter In March 2016, the Financial Accounting Standards Board ("FASB") issued an amendment related to share-based payments to employees, which simplifies several aspects of the accounting for employee share-based payment transactions for public entities. In the first quarter of 2017, we adopted all applicable aspects of this standard on a prospective basis with the exception of the presentation of excess tax benefits on the statement of cash flows, which we adopted on a retrospective basis, and the election to account for forfeitures as they occur, which we adopted on a modified-retrospective basis. The new standard requires companies to recognize all excess tax benefits and tax deficiencies in the income statement when the awards vest or are settled, rather than recognized as additional paid-in capital in the equity section of the balance sheet. Upon adoption, we recognized $0.2 million in discrete tax benefits related to share-based payment accounting, resulting in a lower effective tax rate. This standard also affects the average shares outstanding used in the diluted earnings per share calculation, as we no longer increase or decrease the assumed proceeds from an employee vesting in, or exercising, a share-based payment award by the amount of excess tax benefits or deficiencies taken to additional paid-in capital. The guidance also requires excess tax benefits to be classified as an operating activity in the statement of cash flows rather than a financing activity. Retrospective application of the cash flow presentation requirement resulted in an increase to net cash provided by operating activities of $2.2 million and a decrease to net cash provided by financing activities of $2.2 million for the three months ended March 31, 2016. Further, this guidance permits an entity to make an accounting policy election to either estimate forfeitures on stock compensation awards, as previously required, or to recognize forfeitures as they occur. We elected to change our accounting policy from estimating forfeitures expected to occur to recognizing forfeitures as they occur. This change in policy did not have a material impact on our financial condition, results of operations, or cash flows. In July 2015, the FASB issued guidance requiring inventory to be measured at the lower of cost or net realizable value, which is the estimated selling price in the ordinary course of business, less reasonably predictable costs of completion, disposal and transportation. This guidance is effective prospectively for annual reporting periods beginning after December 15, 2016, and interim reporting periods within those annual reporting periods. We adopted this guidance as of January 1, 2017, when it became effective for us. There was no impact on our consolidated financial statements or results of operations as a result of adopting this standard. Standards/Updates Not Yet Adopted In January 2017, the FASB issued new guidance to simplify the accounting for goodwill impairment. The guidance removes the second step of the goodwill impairment test, which requires a hypothetical purchase price allocation. A goodwill impairment will now be the amount by which a reporting unit’s carrying value exceeds its fair value, not to exceed the carrying amount of goodwill. All other goodwill impairment guidance will remain largely unchanged. Entities will continue to have the option to perform a qualitative assessment to determine if a quantitative impairment test is necessary. The same one-step impairment test will be applied to goodwill at all reporting units, even those with zero or negative carrying amounts. Entities will be required to disclose the amount of goodwill at reporting units with zero or negative carrying amounts. This guidance is effective in 2020, but early adoption is permitted for any impairment tests performed after January 1, 2017. We are currently evaluating the impact that this guidance will have on our financial condition and results of operations. In January 2017, the FASB issued an update under business combinations in an effort to clarify the definition of a business with the objective of adding guidance to assist entities with evaluating whether transactions should be accounted for as acquisitions (or disposals) of assets or as business combinations. The amendments in this update provide a screen to determine when a set of assets is not of a business. The screen requires that when substantially all of the fair value of the gross assets acquired (or disposed of) is concentrated in a single identifiable asset or a group of similar identifiable assets, the set is not a business. This screen reduces the number of transactions that need to be further evaluated. This guidance is effective for fiscal years beginning after December 15, 2017, and interim periods within those fiscal years. Early application is permitted for transactions for which the acquisition (or disposal) date occurs before the effective date of the amendments, if the transaction has not been reported in financial statements that have been issued or made available for issuance. We are currently evaluating the impact that this standard will have on our financial condition, results of operations, and cash flows. In August 2016, the FASB issued guidance to reduce diversity in practice in how certain cash receipts and cash payments are presented and classified in the statement of cash flows. The new amendment is effective for financial statements issued for fiscal years beginning after December 15, 2017 and interim periods within those periods, with early adoption permitted. We are currently evaluating the impact that this standard will have on our statement of cash flows. In February 2016, the FASB issued an amendment related to leases. The new guidance requires the recognition of lease assets and lease liabilities by lessees for all leases greater than one year in duration and classified as operating leases under previous guidance. The new standard is effective for annual periods beginning after December 15, 2018 and interim periods within those periods, with early adoption permitted. This new guidance must be adopted using a modified retrospective transition and requires application of the new guidance at the beginning of the earliest comparative period presented. As of March 31, 2017 and December 31, 2016, the Company's undiscounted minimum contractual commitments under long-term operating leases, which were not recorded on the consolidated balance sheets, were $74.2 million and $79.1 million , respectively, which is an estimate of the effect to total assets and total liabilities that the new accounting standard would have as of those dates. We are currently evaluating the impact that this standard will have on our financial condition, results of operations, and cash flows. In May 2014, the FASB issued guidance (the effective date of which was later delayed) that outlines a single comprehensive model for accounting for revenue arising from contracts with customers, which supersedes most of the existing revenue recognition guidance. This guidance requires an entity to recognize revenue when it transfers 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 and also requires certain additional disclosures. The guidance is effective for interim and annual reporting periods that begin after December 15, 2017. Early adoption of the standard is permitted, but not before the original effective date of December 15, 2016. During the second quarter of 2016, the FASB issued additional revenue recognition guidance that clarifies how an entity identifies performance obligations related to customer contracts as well as the objectives of collectibility, sales and other taxes, non-cash consideration, contract modifications at transition, and technical corrections. The guidance is effective beginning in the first quarter of 2018, and we do not currently plan to early adopt the guidance. The guidance permits two methods of adoption, retrospectively to each prior reporting period presented (full retrospective method), or retrospectively with the cumulative effect of initially applying the guidance recognized at the date of initial application (modified retrospective method). We have not yet selected a transition method, and we continue to evaluate the effect that the updated standard will have on our consolidated financial condition, results of operations and cash flows; however, we do not expect adoption of the guidance to have a material impact on our financial results. We primarily earn our revenue by producing and delivering ready-mixed concrete, aggregates, and related building materials, as requested by our customers primarily through purchase orders. We generally do not have significant customer contracts and do not provide post-delivery services, such as paving or finishing. As such, adoption of the new guidance should not result in significant changes in the amount of revenue recognized or the timing of when such revenue is recognized. For a description of our significant accounting policies, see Note 1 of the consolidated financial statements in our 2016 Form 10-K.

ACQUISITIONS

ACQUISITIONS	3 Months Ended
	Mar. 31, 2017
Business Combinations [Abstract]
ACQUISITIONS	ACQUISITIONS 2016 Acquisitions During 2016 , we completed four acquisitions that expanded our ready-mixed concrete operations in the New York Metropolitan market for total consideration of $142.8 million and two individually immaterial ready-mixed concrete operations in our West Texas market for total consideration of $3.5 million . The combined assets acquired through the New York acquisitions included land, 10 ready-mixed concrete plants, and a fleet of 189 mixer trucks. On February 26, 2016 , we completed the acquisition of all of the assets of Greco Brothers Concrete of L.I., Inc. ("Greco"), located in Brooklyn, New York. On June 24, 2016 , we completed the acquisition of the assets of Nycon Supply Corp. ("Nycon"), located in Queens, New York. On August 10, 2016 , we completed the acquisition of the assets of Jenna Concrete Corp. ("Jenna"), located in Bronx, New York. On August 22, 2016 , we completed the acquisition of the assets of Kings Ready Mix Inc. ("Kings"), located in Brooklyn, New York. In addition, on March 31, 2016 and September 13, 2016 , we acquired two individually immaterial ready-mixed concrete operations in our West Texas market. The consideration for these six acquisitions was satisfied by $131.7 million in cash, $6.1 million in payments deferred over a three -year period, the issuance of $1.0 million of credits applied against existing trade accounts receivable, plus 136,215 shares of our common stock, calculated in accordance with the terms of the purchase agreement, and valued at approximately $7.5 million on the date of issuance. We funded the cash portion of these acquisitions through a combination of cash on hand and borrowings under our asset-based revolving credit facility (the "Revolving Facility"). We made changes to the preliminary purchase price allocations for the 2016 acquisitions during the three months ended March 31, 2017 , primarily related to working capital adjustments. The recording of four of the six business combinations is preliminary, and we expect to record adjustments as we accumulate information needed to estimate the fair value of the assets acquired and liabilities assumed. We expect adjustments including, but not limited to, working capital and the fair value of identifiable intangible assets and property, plant, and equipment. The following table presents the total consideration for the 2016 acquisitions and the provisional amounts related to the assets acquired and liabilities assumed based on the estimated fair values as of the respective acquisition date (in thousands): 2016 Acquisitions Cash $ 9 Accounts receivable (1) 12,314 Inventory 1,249 Other current assets 68 Property, plant and equipment 34,918 Definite-lived intangible assets 47,012 Total assets acquired 95,570 Current liabilities 7,055 Other long-term liabilities 3,165 Total liabilities assumed 10,220 Goodwill 60,136 Total consideration (fair value) (2) $ 145,486 (1) The aggregate fair value of the acquired accounts receivable approximates the aggregate gross contractual amount as of the respective acquisition dates. (2) Deferred payments included at fair value. The accounting for business combinations requires the significant use of estimates and is based on information that was available to management at the time these condensed consolidated financial statements were prepared. We utilized recognized valuation techniques, including the income approach, sales approach, and cost approach to value the net assets acquired. Any changes to the provisional business combination accounting will be made as soon as practical, but no later than one year from the respective acquisition dates. Acquired Intangibles Intangible assets acquired in 2016 totaling $47.0 million consisted of trade names, customer relationships, non-compete agreements, and leasehold interests. The amortization period of these intangible assets range from seven months to seven years . The major classes of intangible assets acquired in the 2016 acquisitions were as follows (in thousands of dollars): Weighted Average Amortization Period (In Years) Fair Value At Acquisition Date Customer relationships 6.01 $ 33,945 Trade names 2.62 2,818 Non-compete agreements 5.00 5,294 Leasehold interests 5.00 4,955 Total $ 47,012 As of March 31, 2017 , the estimated future aggregate amortization expense of definite-lived intangible assets from the 2016 acquisitions was as follows (in thousands): Year Ending December 31, 2017 (remainder of the year) $ 6,370 2018 8,493 2019 8,229 2020 7,700 2021 6,776 Thereafter 3,298 Total $ 40,866 Also included in other non-current liabilities in the accompanying condensed consolidated balance sheet is an unfavorable lease intangible with a gross carrying amount of $0.4 million and a net carrying amount of $0.3 million as of March 31, 2017 . This unfavorable lease intangible will be amortized over its remaining lease term at time of acquisition of five years . During the three months ended March 31, 2017 , we recorded $2.2 million of amortization expense related to these intangible assets and unfavorable lease intangibles. The goodwill ascribed to each of these acquisitions is related to the synergies we expect to achieve with expansion in the markets in which we already operate as well as entry into new metropolitan areas of our existing geographic markets. The goodwill associated with our 2016 acquisitions relates to our ready-mixed concrete reportable segment. We expect the goodwill to generally be deductible for tax purposes. See Note 12 for additional information regarding income taxes. Actual and Pro Forma Impact of Acquisitions During the three months ended March 31, 2017 , we recorded approximately $39.9 million of revenue and $6.3 million of operating income in our condensed consolidated statements of operations related to the 2016 acquisitions. During the three months ended March 31, 2016 , we recorded approximately $0.1 million of revenue and a $0.2 million operating loss in our condensed consolidated statements of operations related to the 2016 acquisitions that occurred during the three months ended March 31, 2016. The unaudited pro forma information presented below reflects the combined financial results for all of the acquisitions completed during 2016, excluding the two 2016 individually immaterial acquisitions in West Texas described above, because historical financial results for these operations were not material and were impractical to obtain from the former owners. All other acquisitions have been included and represent our estimate of the results of operations for the three months ended March 31, 2017 and 2016 as if the 2016 acquisitions had been completed on January 1, 2015 (in thousands, except per share information): Three Months Ended March 31, 2017 2016 Revenue $ 299,133 $ 289,227 Net income (loss) $ 6,995 $ (7,223 ) Income per share, basic $ 0.45 $ (0.49 ) Income per share, diluted $ 0.42 $ (0.49 ) The above pro forma results are unaudited and were prepared based on the historical U.S. GAAP results of the Company and the historical results of the four acquired companies for which financial information was available, based on data provided by the former owners. These results are not necessarily indicative of what the Company's actual results would have been had the 2016 acquisitions occurred on January 1, 2015. The unaudited pro forma net income (loss) and net income (loss) per share amounts above reflect the following adjustments (in thousands): Three Months Ended March 31, 2017 2016 Decrease (increase) in intangible amortization expense $ 103 $ (2,080 ) Exclusion of buyer transaction costs $ (2 ) $ 548 Decrease (increase) in interest expense $ 83 $ (90 ) Increase in income tax expense $ (68 ) $ (1,588 ) The unaudited pro forma results do not reflect any operational efficiencies or potential cost savings that may occur as a result of consolidation of the operations.

Discontinued Operations and Disposal Groups [Abstract]
DISCONTINUED OPERATIONS	DISCONTINUED OPERATIONS Discontinued operations primarily relate to real estate leases and subleases of our former precast concrete operations disposed of in prior years.

Senior Unsecured Notes due 2024 On June 7, 2016, we completed an offering of $400.0 million aggregate principal amount of 6.375% senior unsecured notes due 2024 (the "2024 Notes"). We used a portion of the net proceeds from the 2024 Notes to repay all of our outstanding borrowings under the Revolving Facility and to redeem all $200.0 million of our outstanding 8.5% senior secured notes due 2018. On January 9, 2017, we completed an offering of $200.0 million aggregate principal amount of additional 2024 Notes (the "Additional Notes") at an issue price of 105.75% . The terms of the Additional Notes are identical to the terms of the 2024 Notes, other than the issue date, the issue price, the first interest payment date and the provisions relating to transfer restrictions and registration rights. We used the net proceeds from the offering of the Additional Notes, which were approximately $208.4 million , to increase our liquidity. The 2024 Notes are governed by an indenture (the “Indenture”) dated as of June 7, 2016, by and among U.S. Concrete, Inc., as issuer, the subsidiary guarantors party thereto, and U.S. Bank National Association, as trustee. The 2024 Notes accrue interest at a rate of 6.375% per annum. We pay interest on the 2024 Notes on June 1 and December 1 of each year. The 2024 Notes mature on June 1, 2024, and are redeemable at our option prior to maturity at prices specified in the Indenture. The Indenture contains negative covenants that restrict our ability and our restricted subsidiaries' ability to engage in certain transactions, as described below, and also contains customary events of default. The Indenture contains covenants that, among other things, limit our ability and the ability of our restricted subsidiaries to: • incur additional debt or issue disqualified stock or preferred stock; • pay dividends or make other distributions, repurchase or redeem our stock or subordinated indebtedness or make certain investments; • sell assets and issue capital stock of our restricted subsidiaries; • incur liens; • allow to exist certain restrictions on the ability of our restricted subsidiaries to pay dividends or make other payments to us; • enter into transactions with affiliates; • consolidate, merge or sell all or substantially all of our assets; and • designate our subsidiaries as unrestricted subsidiaries. The 2024 Notes are issued by U.S. Concrete, Inc. (the "Parent"). Our obligations under the 2024 Notes are jointly and severally and fully and unconditionally guaranteed on a senior unsecured basis by each of our restricted subsidiaries that guarantees any obligations under the Revolving Facility or that guarantees certain of our other indebtedness or certain indebtedness of our restricted subsidiaries (other than foreign restricted subsidiaries that guarantee only indebtedness incurred by another foreign subsidiary). U.S. Concrete, Inc. does not have any independent assets or operations, and none of its foreign subsidiaries guarantee the 2024 Notes. There are no significant restrictions on the ability of the Company or any guarantor to obtain funds from its subsidiaries by dividend or loan. For additional information regarding our guarantor and non-guarantor subsidiaries, see the information set forth in Note 17. The 2024 Notes and the guarantees thereof are effectively subordinated to all of our and our guarantors' existing and future secured obligations, including obligations under the Revolving Facility, to the extent of the value of the collateral securing such obligations; senior in right of payment to any of our and our guarantors' future subordinated indebtedness; pari passu in right of payment with any of our and our guarantors' existing and future senior indebtedness, including our and our guarantors' obligations under the Revolving Facility; and structurally subordinated to all existing and future indebtedness and other liabilities, including preferred stock, of any non-guarantor subsidiaries. Senior Secured Credit Facility On November 18, 2015, we entered into the Second Amended and Restated Loan and Security Agreement (the “Second A/R Loan Agreement”) with Bank of America, N.A., as administrative agent, and certain financial institutions named therein, as lenders (the "Lenders"), which amended and restated the First Amended and Restated Loan and Security Agreement dated October 29, 2013 (the "2013 Loan Agreement") and provides us with the Revolving Facility of up to $250.0 million . The maturity date of the Revolving Facility is November 18, 2020. As of March 31, 2017 , we had no outstanding borrowings on the Second A/R Loan Agreement, and we had $14.3 million of undrawn standby letters of credit under the Revolving Facility. Our actual maximum credit availability under the Revolving Facility varies from time to time and is determined by calculating the value of our eligible accounts receivable, inventory, mixer trucks and machinery, minus reserves imposed by the Lenders and other adjustments, all as specified in the Second A/R Loan Agreement and discussed further below. Our availability under the Revolving Facility at March 31, 2017 decreased to $208.2 million from $221.3 million at December 31, 2016 . The Second A/R Loan Agreement also contains a provision for over-advances and protective advances by Lenders, in each case, of up to $25.0 million in excess of borrowing base levels. The Second A/R Loan Agreement provides for swingline loans, up to a $15.0 million sublimit, and letters of credit, up to a $30.0 million sublimit. Up to $30.0 million of the Revolving Facility is available for the issuance of letters of credit, and any such issuance of letters of credit will reduce the amount available for loans under the Revolving Facility. Loans under the Revolving Facility are limited by a borrowing base which is equal to the lessor of (a) the aggregate amount of Revolver Commitments minus each of the LC Reserve and the Tax Amount, all as defined in the Second A/R Loan Agreement, and (b) (i) 90% of the face amount of eligible accounts receivable (reduced to 85% under certain circumstances), plus (ii) the lesser of (x) 70% of the value of eligible inventory or (y) 90% of the product of (A) the net orderly liquidation value of inventory divided by the value of the inventory and (B) multiplied by the value of eligible inventory, plus (iii) (w) 85% of the net orderly liquidation value (as determined by the most recent appraisal) of eligible trucks, plus (x) 80% of the cost of eligible trucks that have been acquired since the date of the latest appraisal of eligible trucks minus (y) 85% of the net orderly liquidation value of eligible trucks that have been sold since the date of the latest appraisal, minus (z) 85% of the depreciation amount applicable to eligible trucks, plus (iv) (x) 85% of the net orderly liquidation value (as determined by the most recent appraisal) of eligible machinery minus (y) 85% of the net orderly liquidation value of eligible machinery that have been sold since the date of the latest appraisal, minus (z) 85% of the depreciation amount applicable to eligible machinery, minus (v) the Availability Reserve and minus (vi) the Tax Amount, each as defined in the Second A/R Loan Agreement; provided that, notwithstanding anything herein to the contrary, in determining the borrowing base, the borrowing base pursuant to this clause (b), the borrowing base attributable to the eligible trucks and eligible machinery set forth in clauses (b) (iii) and (iv) above shall not exceed 30% of the borrowing base as of such date of determination. The administrative agent may, in its permitted discretion, reduce the advance rates set forth above, adjust reserves or reduce one or more of the other elements used in computing the borrowing base. The Second A/R Loan Agreement also requires that we, upon the occurrence of certain events, maintain a fixed charge coverage ratio of at least 1.0 to 1.0 for each period of 12 calendar months, as determined in accordance with the Second A/R Loan Agreement. For the trailing 12-month period ended March 31, 2017 , our fixed charge coverage ratio was 2.97 to 1.0. As of March 31, 2017 , we were in compliance with all covenants under the Second A/R Loan Agreement. The Second A/R Loan Agreement is secured by a first priority lien on substantially all of the personal property of the Company and our guarantors, subject to permitted liens and certain exceptions. Capital Leases and Other Financing We have a series of promissory notes with various lenders for the purchase of mixer trucks and other machinery and equipment in an aggregate principal amount of $33.9 million , with fixed annual interest rates ranging from less than 2.50% to 4.86% , payable monthly for terms ranging from less than one to five years. We have leasing agreements with various other lenders for the purchase of mixer trucks and other machinery and equipment for a total principal amount of $53.7 million , with fixed annual interest rates ranging from less than 0.01% to 5.24% , payable monthly for terms ranging from two to five years. The lease terms include one dollar buyout options at the end of the lease terms. Accordingly, these financings have been classified as capital leases. The current portion of capital leases included in current maturities of long-term debt was $10.8 million as of March 31, 2017 and $9.8 million as of December 31, 2016 . The weighted average interest rate of our capital leases and other financings was 3.12% as of March 31, 2017 and 3.11% as of December 31, 2016 .

Warrants and Rights Note Disclosure [Abstract]
WARRANTS	WARRANTS On August 31, 2010, we issued warrants to acquire common stock in two tranches: Class A Warrants to purchase an aggregate of approximately 1.5 million shares of common stock and Class B Warrants to purchase an aggregate of approximately 1.5 million shares of common stock (collectively, the "Warrants"). The Warrants were issued to holders of our predecessor common stock pro rata based on a holder’s stock ownership as of August 31, 2010 and will expire on August 31, 2017. The Warrants are included in derivative liabilities on the accompanying condensed consolidated balance sheets (see Note 10) and are recorded at their fair value (see Note 11). The Warrants are also included in the potentially dilutive securities included in the calculation of diluted earnings (loss) per share as shares of our common stock would be issued if the Warrants were exercised (see Note 14). The Warrants are classified as a current liability on the accompanying condensed consolidated balance sheets, as they can be exercised by the holders at any time. As of March 31, 2017 , there were approximately 0.7 million Class A Warrants and 0.4 million Class B Warrants outstanding.

FAIR VALUE DISCLOSURES

FAIR VALUE DISCLOSURES	3 Months Ended

Fair Value Disclosures [Abstract]
FAIR VALUE DISCLOSURES	FAIR VALUE DISCLOSURES Fair value is defined as the exit price, or the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants as of the measurement date. Accounting guidance also establishes a hierarchy for inputs used in measuring fair value that maximizes the use of observable inputs and minimizes the use of unobservable inputs by requiring that the most observable inputs be used when available. Observable inputs are inputs market participants would use in valuing the asset or liability and are developed based on market data obtained from independent sources. Unobservable inputs are inputs that reflect our assumptions about the factors market participants would use in valuing the asset or liability. The guidance establishes three levels of inputs that may be used to measure fair value: Level 1—Quoted prices in active markets for identical assets or liabilities. Level 2—Inputs other than Level 1 that are observable, either directly or indirectly, such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities. Level 3—Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities. Assets and liabilities are classified in their entirety based on the lowest level of input that is significant to the fair value measurements. We review the fair value hierarchy classification on a quarterly basis. Changes in the observability of valuation inputs may result in a reclassification of levels for certain assets and liabilities within the fair value hierarchy. The following tables present our fair value hierarchy for liabilities measured at fair value on a recurring basis as of March 31, 2017 and December 31, 2016 (in thousands): March 31, 2017 Total Level 1 Level 2 Level 3 Derivative – Warrants $ 45,815 $ — $ 45,815 $ — Contingent consideration, including current portion (1) (2) (3) (4) 30,691 — — 30,691 $ 76,506 $ — $ 45,815 $ 30,691 December 31, 2016 Total Level 1 Level 2 Level 3 Derivative – Warrants $ 57,415 $ — $ 57,415 $ — Contingent consideration, including current portion (1) (2) (3) (4) (5) 32,212 — — 32,212 $ 89,627 $ — $ 57,415 $ 32,212 (1) The current portion of contingent consideration is included in accrued liabilities in our condensed consolidated balance sheets. The long-term portion of contingent consideration is included in other long-term obligations and deferred credits in our condensed consolidated balance sheets. (2) Includes the fair value of the earn-out payments associated with the 2015 acquisition of Right Away Redy Mix, Inc. (the "Right Away Earn-out"). The fair value was determined based on expected payouts that will be due to the former owners based on probability-weighted assumptions related to the achievement of annual sales volume milestones, using a discount rate of 8.50% as of both March 31, 2017 and December 31, 2016 . The fair value of the Right Away Earn-out was $3.4 million and $3.9 million as of March 31, 2017 and December 31, 2016 , respectively. The remaining Right Away Earn-out payments were capped at $4.3 million and $5.0 million as of March 31, 2017 and December 31, 2016 , respectively. (3) Includes the fair value of the contingent consideration associated with the 2015 acquisition of Ferrara Bros. Building Materials Corp. ("Ferrara Bros. Contingent Consideration"). The fair value was determined based on the expected vesting of incentive awards granted to the former owners at acquisition based on probability-weighted assumptions related to the achievement of certain annual EBITDA thresholds, using a discount rate of 8.75% as of both March 31, 2017 and December 31, 2016 . The fair value of the Ferrara Bros. Contingent Consideration was $26.7 million and $26.3 million as of March 31, 2017 and December 31, 2016 , respectively. The Ferrara Bros. Contingent Consideration payments were capped at $35.0 million as of both March 31, 2017 and December 31, 2016 . (4) Includes the fair value of the earn-out payments associated with the 2015 acquisition of DuBrook Concrete, Inc. ("DuBrook Earn-out"). The fair value was determined based on the expected payouts that will be due to the former owners based on probability-weighted assumptions related to the achievement of sales volume milestones, using a discount rate of 15.75% as of both March 31, 2017 and December 31, 2016 . The fair value of the DuBrook Earn-out was $0.6 million as of both March 31, 2017 and December 31, 2016 . The Dubrook Earn-out payments are not capped; however, we do not expect total payments to be in excess of $0.7 million as of both March 31, 2017 and December 31, 2016 , respectively. (5) Includes the fair value of the earn-out payments associated with the 2012 acquisition of Bode Gravel Co. and Bode Concrete LLC ("Bode Earn-out"). The fair value was determined based on expected payouts that will be due to the former owners based on the achievement of certain incremental sales volume milestones, using a contractual discount rate of 7.0% . These payments were capped at a fair value of $1.4 million as of December 31, 2016 . The final Bode Earn-out payment was made in January 2017. The liability for the Warrants was valued utilizing a Black-Scholes-Merton model. Inputs into the model were based upon observable market data. The key inputs in determining our derivative liabilities include our stock price, stock price volatility, and risk free interest rates. As of March 31, 2017 , observable market data existed for all of the key inputs in determining the fair value of our Warrants. The liabilities for the Right Away Earn-out and the Ferrara Bros. Contingent Consideration were valued using Monte Carlo simulations which incorporated probability-weighted assumptions related to the achievement of specific milestones mentioned above. The liabilities for the Bode Earn-out, the DuBrook Earn-out, and the contingent consideration associated with one of the individually immaterial 2015 acquisitions were valued using a discounted cash flow technique. Inputs into the model were based upon observable market data where possible. Where observable market data did not exist, we modeled inputs based upon similar observable inputs. The key inputs in determining the fair value of the contingent consideration as of March 31, 2017 and December 31, 2016 included discount rates ranging from 8.50% to 15.75% and management's estimates of future sales volumes and EBITDA. Changes in these inputs will impact the valuation of our contingent consideration obligations and will result in gain or loss each quarterly period. A reconciliation of the changes in Level 3 fair value measurements from December 31, 2016 to March 31, 2017 is provided below (in thousands): Contingent Consideration Balance at December 31, 2016 $ 32,212 Total losses included in earnings (1) 608 Payment on contingent consideration (2,129 ) Balance at March 31, 2017 $ 30,691 (1) Represents the net loss on revaluation of contingent consideration, which is included in loss on revaluation of contingent consideration in our condensed consolidated statements of operations. Our other financial instruments consist of cash and cash equivalents, accounts receivable, accounts payable, and long-term debt. We consider the carrying values of cash and cash equivalents, accounts receivable and accounts payable to be representative of their respective fair values because of their short-term maturities or expected settlement dates. The fair value of our 2024 Notes, estimated based on broker/dealer quoted market prices, was $624.0 million as of March 31, 2017 . The carrying value of outstanding amounts under our Second A/R Loan Agreement approximates fair value due to the floating interest rate.

INCOME TAXES

INCOME TAXES	3 Months Ended

Income Tax Disclosure [Abstract]
INCOME TAXES	INCOME TAXES We recorded income tax expense allocated to continuing operations of $6.7 million and $2.0 million for the three months ended March 31, 2017 and 2016 , respectively. We recorded a tax benefit of $0.1 million allocated to discontinued operations for both the three months ended March 31, 2017 and 2016 . For the three months ended March 31, 2017, our effective tax rate differed from the federal statutory rate primarily due to adjustments related to certain state net operating loss (“NOL”) carryforwards that will not be utilized prior to expiration and other cumulative adjustments to deferred income taxes, which both resulted in additional income tax expense. In addition, the adoption of ASU 2016-09 on January 1, 2017 (see Note 2) required the current period income tax benefit related to stock compensation to be reflected in the income statement instead of additional paid-in-capital, as previously required. For the three months ended March 31, 2016 , our effective tax rate differed from the federal statutory tax rate primarily due to the application of a valuation allowance that reduced the recognized benefit of our deferred tax assets. In addition, certain state income taxes are calculated on a basis other than pre-tax income (loss). In addition, for both the three months ended March 31, 2017 and 2016, our effective tax rate differed from the federal statutory rate due to the tax impact of derivative gains and losses related to our Warrants. These derivative gains and losses were excluded from the calculation of our income tax provision and were treated as an unrecognized tax position. For the three months ended March 31, 2017 , our tax provision excluded $0.7 million of tax expense related to our $1.9 million derivative gain. For the three months ended March 31, 2016, our tax provision excluded $2.5 million related to the unrecognized tax benefit. In accordance with U.S. GAAP, we reduce the value of deferred tax assets to the amount that is more likely than not to be realized in future periods. The ultimate realization of the benefit of deferred tax assets from deductible temporary differences or tax carryovers depends on generating sufficient taxable income during the periods in which those temporary differences become deductible. We considered the scheduled reversal of deferred tax liabilities, projected future taxable income, and tax planning strategies in making this assessment. Based on these considerations, we relied upon the reversal of certain deferred tax liabilities to realize a portion of our deferred tax assets and established valuation allowances as of March 31, 2017 and December 31, 2016 for other deferred tax assets because of uncertainty regarding their ultimate realization. Our total net deferred tax liability was approximately $10.2 million as of March 31, 2017 and approximately $7.7 million as of December 31, 2016 . We made income tax payments of approximately $5.7 million and $2.1 million during the three months ended March 31, 2017 and 2016 , respectively. We record changes in our unrecognized tax benefits based on anticipated federal and state tax filing positions on a quarterly basis. For the three months ended March 31, 2017 and 2016 , we recorded unrecognized tax benefits of $0.6 million and $2.7 million , respectively.

STOCKHOLDERS' EQUITY	STOCKHOLDERS' EQUITY Common Stock and Preferred Stock The following table presents information regarding our common stock (in thousands): March 31, 2017 December 31, 2016 Shares authorized 100,000 100,000 Shares outstanding at end of period 16,020 15,696 Shares held in treasury 899 888 There was no preferred stock issued or outstanding as of March 31, 2017 or December 31, 2016 . Share Repurchase Program In May 2014, our Board authorized a program to repurchase up to $50.0 million of our outstanding common stock (the "Share Repurchase Program") until the earlier of March 31, 2017, or a determination by the Board to discontinue the Share Repurchase Program. We made no repurchases of our common stock during the three months ended March 31, 2017 and 2016 under the Share Repurchase Program. In March 2017, given the impending expiration of our Share Repurchase Program, our Board authorized a new share repurchase program to repurchase up to $50.0 million of our outstanding common stock (the "Second Share Repurchase Program") effective April 1, 2017 until the earlier of March 31, 2020, or a determination by the Board to discontinue the Second Share Repurchase Program. Treasury Stock Employees may elect to satisfy their minimum tax obligations on the vesting of their equity awards by having the required tax payments withheld based on a number of vested shares having an aggregate value on the date of vesting equal to the tax obligation. As a result of such employee elections, we withheld approximately 11,000 shares with a total value of approximately $0.7 million during the three months ended March 31, 2017 . We withheld approximately 1,200 shares with a total value of approximately $0.1 million during the three months ended March 31, 2016 . We accounted for the minimum withholding of these shares as treasury stock.

Earnings Per Share [Abstract]
NET EARNINGS (LOSS) PER SHARE	NET EARNINGS (LOSS) PER SHARE Basic earnings (loss) per share is computed by dividing net earnings (loss) by the weighted average number of common shares outstanding during the period. Diluted earnings (loss) per share is computed by dividing net earnings (loss) by the weighted average number of common shares outstanding during the period after giving effect to all potentially dilutive securities outstanding during the period. The following is a reconciliation of the components of the basic and diluted earnings (loss) per share calculations for the three months ended March 31, 2017 and 2016 (in thousands): Three Months Ended March 31, 2017 2016 (1) Numerator: Income (loss) from continuing operations $ 7,002 $ (9,839 ) Loss from discontinued operations, net of taxes (122 ) (188 ) Numerator for diluted earnings (loss) per share $ 6,880 $ (10,027 ) Denominator: Basic weighted average common shares outstanding 15,498 14,789 Restricted stock awards and restricted stock units 117 — Warrants 851 — Stock options 17 — Denominator for diluted earnings (loss) per share 16,483 14,789 (1) We reported a loss from continuing operations for the three months ended March 31, 2016, and thus the share count used in the basic and diluted earnings per share calculation is the same. For the three months ended March 31, 2017 and 2016 , our potentially dilutive shares include the shares underlying our restricted stock awards, restricted stock units, stock options and Warrants. The following table shows the type and number (in thousands) of potentially dilutive shares excluded from the diluted earnings (loss) per share calculations for the periods presented as their effect would have been anti-dilutive or they have not met their performance target: Three Months Ended March 31, 2017 2016 Potentially dilutive shares: Unvested restricted stock awards and restricted stock units 165 400 Stock options — 30 Warrants — 2,078 Total potentially dilutive shares 165 2,508

Commitments and Contingencies Disclosure [Abstract]
COMMITMENTS AND CONTINGENCIES	COMMITMENTS AND CONTINGENCIES Legal Proceedings From time to time, and currently, we are subject to various claims and litigation brought by employees, customers and other third-parties for, among other matters, personal injuries, property damages, product defects and delay damages that have, or allegedly have, resulted from the conduct of our operations. As a result of these types of claims and litigation, we must periodically evaluate the probability of damages being assessed against us and the range of possible outcomes. In each reporting period, if we determine that the likelihood of damages being assessed against us is probable, and if we believe we can estimate a range of possible outcomes, then we will record a liability. The amount of the liability will be based upon a specific estimate, if we believe a specific estimate to be likely, or it will reflect the low end of our range. Currently, there are no material legal proceedings pending against us. In the future, we may receive funding deficiency demands from multi-employer pension plans to which we contribute. We are unable to estimate the amount of any potential future funding deficiency demands because the actions of each of the contributing employers in the plans has an effect on each of the other contributing employers and the development of a rehabilitation plan by the trustees and subsequent submittal to and approval by the Internal Revenue Service is not predictable. Further, the allocation of fund assets and return assumptions by trustees are variable, as are actual investment returns relative to the plan assumptions. As of March 31, 2017 , there are no material product defect claims pending against us. Accordingly, our existing accruals for claims against us do not reflect any material amounts relating to product defect claims. While our management is not aware of any facts that would reasonably be expected to lead to material product defect claims against us that would have a material adverse effect on our business, financial condition or results of operations, it is possible that claims could be asserted against us in the future. We do not maintain insurance that would cover all damages resulting from product defect claims. In particular, we generally do not maintain insurance coverage for the cost of removing and rebuilding structures. In addition, our indemnification arrangements with contractors or others, when obtained, generally provide only limited protection against product defect claims. Due to inherent uncertainties associated with estimating claims in our business, we cannot estimate the amount of any future loss that may be attributable to product defect claims related to ready-mixed concrete we have delivered prior to March 31, 2017 . On March 28, 2017, Hans Ruedelstein, individually and on behalf of all others situated, filed a purported class action lawsuit in the United States District Court of Northern Texas, Fort Worth Division, against the Company, William J. Sandbrook, William M. Brown and Joseph C. Tusa, Jr. alleging violations of certain federal securities laws. The case was filed purportedly on behalf of purchasers of the Company's stock between March 6, 2015 and March 23, 2017. The complaint does not specify an amount of damages sought. The Company denies the allegations in the complaint and intends to vigorously pursue its defense. We believe that the resolution of all litigation currently pending or threatened against us or any of our subsidiaries will not materially exceed our existing accruals for those matters. However, because of the inherent uncertainty of litigation, there is a risk that we may have to increase our accruals for one or more claims or proceedings to which we or any of our subsidiaries is a party as more information becomes available or proceedings progress, and any such increase in accruals could have a material adverse effect on our consolidated financial condition or results of operations. We expect in the future that we and our operating subsidiaries will, from time to time, be a party to litigation or administrative proceedings that arise in the normal course of our business. We are subject to federal, state and local environmental laws and regulations concerning, among other matters, air emissions and wastewater discharge. Our management believes we are in substantial compliance with applicable environmental laws and regulations. From time to time, we receive claims from federal and state environmental regulatory agencies and entities asserting that we may be in violation of environmental laws and regulations. Based on experience and the information currently available, our management does not believe that these claims will materially exceed our related accruals. Despite compliance and experience, it is possible that we could be held liable for future charges, which might be material, but are not currently known to us or cannot be estimated by us. In addition, changes in federal or state laws, regulations or requirements, or discovery of currently unknown conditions, could require additional expenditures. As permitted under Delaware law, we have agreements that provide indemnification of officers and directors for certain events or occurrences while the officer or director is or was serving at our request in such capacity. The maximum potential amount of future payments that we could be required to make under these indemnification agreements is not limited; however, we have a director and officer insurance policy that potentially limits our exposure and enables us to recover a portion of future amounts that may be paid. As a result of the insurance policy coverage, we believe the estimated fair value of these indemnification agreements is minimal. Accordingly, we have not recorded any liabilities for these agreements as of March 31, 2017 . We and our subsidiaries are parties to agreements that require us to provide indemnification in certain instances when we acquire businesses and real estate and in the ordinary course of business with our customers, suppliers, lessors and service providers. Insurance Programs We maintain third-party insurance coverage against certain risks in amounts we believe are reasonable. Under certain components of our insurance program, we share the risk of loss with our insurance underwriters by maintaining high deductibles subject to aggregate annual loss limitations. Generally, our deductible retentions per occurrence for auto, workers’ compensation and general liability insurance programs are $1.0 million , although certain of our operations are self-insured for workers’ compensation. We fund these deductibles and record an expense for expected losses under the programs. We determine the expected losses using a combination of our historical loss experience and subjective assessments of our future loss exposure. The estimated losses are subject to uncertainty from various sources, including changes in claims reporting patterns, claims settlement patterns, judicial decisions, legislation and economic conditions. Although we believe the estimated losses we have recorded are reasonable, significant differences related to the items we have noted above could materially affect our insurance obligations and future expense. The amount recorded in accrued liabilities in our condensed consolidated balance sheet for estimated losses was $14.2 million as of March 31, 2017 , compared to $13.5 million as of December 31, 2016 . Performance Bonds In the normal course of business, we are contingently liable for performance under $38.7 million in performance bonds that various contractors, states and municipalities have required as of March 31, 2017 . The bonds principally relate to construction contracts, reclamation obligations, licensing and permitting. We and our subsidiaries have indemnified the underwriting insurance company against any exposure under the performance bonds. No material claims have been made against these bonds as of March 31, 2017 . Employment Agreements We have employment agreements with executive officers and certain key members of management under which severance payments would become payable in the event of specified terminations without cause or after a change of control.

SEGMENT INFORMATION

Segment Reporting [Abstract]
SEGMENT INFORMATION	SEGMENT INFORMATION Our two reportable segments consist of ready-mixed concrete and aggregate products as described below. Our ready-mixed concrete segment produces and sells ready-mixed concrete. This segment serves the following markets: Texas, Northern California, New York, New Jersey, Washington, D.C., Oklahoma, and the U.S. Virgin Islands. Our aggregate products segment includes crushed stone, sand and gravel products and serves the North Texas, West Texas, New York, New Jersey, southern Oklahoma, and U.S. Virgin Islands markets in which our ready-mixed concrete segment operates. Other products not associated with a reportable segment include our building materials stores, hauling operations, lime slurry, ARIDUS ® Rapid Drying Concrete technology, brokered product sales, a recycled aggregates operation, an aggregate distribution operation, and an industrial waterfront marine terminal and sales yard. The financial results of the acquisitions have been included in their respective reportable segment or in other products as of their respective acquisition dates. Our customers are generally involved in the construction industry, which is a cyclical business and is subject to general and more localized economic conditions. In addition, our business is impacted by seasonal variations in weather conditions, which vary by regional market. Accordingly, demand for our products and services during the winter months is typically lower than in other months of the year because of inclement weather. Also, sustained periods of inclement weather and other adverse weather conditions could cause the delay of construction projects during other times of the year. Our chief operating decision maker evaluates segment performance and allocates resources based on Adjusted EBITDA. We define Adjusted EBITDA as income (loss) from continuing operations plus the provision (benefit) for income taxes, net interest expense, depreciation, depletion and amortization, derivative gain (loss), gain (loss) on revaluation of contingent consideration, and gain (loss) on extinguishment of debt. Additionally, we adjust Adjusted EBITDA for items similar to certain of those used in calculating our compliance with debt covenants. The additional items that are adjusted to determine our Adjusted EBITDA are: • non-cash stock compensation expense, • acquisition-related professional fees, and • corporate officer severance expense. We consider Adjusted EBITDA to be an indicator of the operational strength and performance of our business. We have included Adjusted EBITDA because it is a key financial measure used by our management to (1) internally measure our operating performance and (2) assess our ability to service our debt, incur additional debt, and meet our capital expenditure requirements. Adjusted EBITDA should not be construed as an alternative to, or a better indicator of, operating income or loss, is not based on U.S. GAAP, and is not a measure of our cash flows or ability to fund our cash needs. Our measurements of Adjusted EBITDA may not be comparable to similarly titled measures reported by other companies, and may not be comparable to similarly titled measures used in our various agreements, including the Second A/R Loan Agreement and the Indenture. We account for inter-segment sales at market prices. Corporate includes executive, administrative, financial, legal, human resources, business development and risk management activities which are not allocated to reportable segments and are excluded from segment Adjusted EBITDA. Eliminations include transactions to account for intercompany activity.

Subsequent Events [Abstract]
SUBSEQUENT EVENT	SUBSEQUENT EVENT On April 7, 2017, we completed the acquisition of certain assets from Corbett Aggregate Companies, LLC ("Corbett"), in Quinton, New Jersey. The acquisition was funded with $29.2 million of existing cash and potential future consideration. The acquisition included approximately 401 acres of land with over 35 million tons of proven aggregates reserves. Also included in the acquisition was a long-term lease with the South Jersey Port Corporation for an export dock located approximately six miles from the aggregates operation, as well as the exclusive right to move coarse and fine aggregates through the North Shore Terminal located on Staten Island, New York. The acquisition furthers our strategy of vertical integration and increases our self-sufficiency of internal aggregate products. We will prepare the preliminary purchase price allocation for this acquisition as soon as practical, but no later than one year from the acquisition date.

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	The accompanying unaudited condensed consolidated financial statements include the accounts of U.S. Concrete, Inc. and its subsidiaries (collectively, "we," "us," "our," "U.S. Concrete," or the "Company") and have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission (the "SEC") for reporting interim financial information. Some information and footnote disclosures normally included in financial statements prepared in accordance with generally accepted accounting principles in the United States ("U.S. GAAP") have been condensed or omitted pursuant to the SEC’s rules and regulations. These unaudited condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements and related notes in our Annual Report on Form 10-K for the year ended December 31, 2016 (the " 2016 Form 10-K"). In the opinion of our management, all adjustments necessary to state fairly the information in our unaudited condensed consolidated financial statements and to make such financial statements not misleading have been included. All adjustments are of a normal or recurring nature. Operating results for the three months ended March 31, 2017 are not necessarily indicative of our results expected for the year ending December 31, 2017 , or for any future period.
Use of Estimates	The preparation of financial statements and accompanying notes in conformity with U.S. GAAP requires management to make estimates and assumptions in determining the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities as of the date of the financial statements and the reported amounts of revenue and expenses during the reporting period. Actual results could differ from those estimates. Estimates and assumptions that we consider critical and that involve complex judgments in the preparation of our financial statements include those related to our business combinations, goodwill and goodwill impairment, impairment of long-lived assets, accruals for self-insurance programs, income taxes, derivative instruments, and contingent consideration.
Reclassifications	Certain reclassifications have been made to prior year balances to conform with the current year presentation.
Amendments Adopted This Quarter and Standards/Updates Not Yet Adopted	Amendments Adopted This Quarter In March 2016, the Financial Accounting Standards Board ("FASB") issued an amendment related to share-based payments to employees, which simplifies several aspects of the accounting for employee share-based payment transactions for public entities. In the first quarter of 2017, we adopted all applicable aspects of this standard on a prospective basis with the exception of the presentation of excess tax benefits on the statement of cash flows, which we adopted on a retrospective basis, and the election to account for forfeitures as they occur, which we adopted on a modified-retrospective basis. The new standard requires companies to recognize all excess tax benefits and tax deficiencies in the income statement when the awards vest or are settled, rather than recognized as additional paid-in capital in the equity section of the balance sheet. Upon adoption, we recognized $0.2 million in discrete tax benefits related to share-based payment accounting, resulting in a lower effective tax rate. This standard also affects the average shares outstanding used in the diluted earnings per share calculation, as we no longer increase or decrease the assumed proceeds from an employee vesting in, or exercising, a share-based payment award by the amount of excess tax benefits or deficiencies taken to additional paid-in capital. The guidance also requires excess tax benefits to be classified as an operating activity in the statement of cash flows rather than a financing activity. Retrospective application of the cash flow presentation requirement resulted in an increase to net cash provided by operating activities of $2.2 million and a decrease to net cash provided by financing activities of $2.2 million for the three months ended March 31, 2016. Further, this guidance permits an entity to make an accounting policy election to either estimate forfeitures on stock compensation awards, as previously required, or to recognize forfeitures as they occur. We elected to change our accounting policy from estimating forfeitures expected to occur to recognizing forfeitures as they occur. This change in policy did not have a material impact on our financial condition, results of operations, or cash flows. In July 2015, the FASB issued guidance requiring inventory to be measured at the lower of cost or net realizable value, which is the estimated selling price in the ordinary course of business, less reasonably predictable costs of completion, disposal and transportation. This guidance is effective prospectively for annual reporting periods beginning after December 15, 2016, and interim reporting periods within those annual reporting periods. We adopted this guidance as of January 1, 2017, when it became effective for us. There was no impact on our consolidated financial statements or results of operations as a result of adopting this standard. Standards/Updates Not Yet Adopted In January 2017, the FASB issued new guidance to simplify the accounting for goodwill impairment. The guidance removes the second step of the goodwill impairment test, which requires a hypothetical purchase price allocation. A goodwill impairment will now be the amount by which a reporting unit’s carrying value exceeds its fair value, not to exceed the carrying amount of goodwill. All other goodwill impairment guidance will remain largely unchanged. Entities will continue to have the option to perform a qualitative assessment to determine if a quantitative impairment test is necessary. The same one-step impairment test will be applied to goodwill at all reporting units, even those with zero or negative carrying amounts. Entities will be required to disclose the amount of goodwill at reporting units with zero or negative carrying amounts. This guidance is effective in 2020, but early adoption is permitted for any impairment tests performed after January 1, 2017. We are currently evaluating the impact that this guidance will have on our financial condition and results of operations. In January 2017, the FASB issued an update under business combinations in an effort to clarify the definition of a business with the objective of adding guidance to assist entities with evaluating whether transactions should be accounted for as acquisitions (or disposals) of assets or as business combinations. The amendments in this update provide a screen to determine when a set of assets is not of a business. The screen requires that when substantially all of the fair value of the gross assets acquired (or disposed of) is concentrated in a single identifiable asset or a group of similar identifiable assets, the set is not a business. This screen reduces the number of transactions that need to be further evaluated. This guidance is effective for fiscal years beginning after December 15, 2017, and interim periods within those fiscal years. Early application is permitted for transactions for which the acquisition (or disposal) date occurs before the effective date of the amendments, if the transaction has not been reported in financial statements that have been issued or made available for issuance. We are currently evaluating the impact that this standard will have on our financial condition, results of operations, and cash flows. In August 2016, the FASB issued guidance to reduce diversity in practice in how certain cash receipts and cash payments are presented and classified in the statement of cash flows. The new amendment is effective for financial statements issued for fiscal years beginning after December 15, 2017 and interim periods within those periods, with early adoption permitted. We are currently evaluating the impact that this standard will have on our statement of cash flows. In February 2016, the FASB issued an amendment related to leases. The new guidance requires the recognition of lease assets and lease liabilities by lessees for all leases greater than one year in duration and classified as operating leases under previous guidance. The new standard is effective for annual periods beginning after December 15, 2018 and interim periods within those periods, with early adoption permitted. This new guidance must be adopted using a modified retrospective transition and requires application of the new guidance at the beginning of the earliest comparative period presented. As of March 31, 2017 and December 31, 2016, the Company's undiscounted minimum contractual commitments under long-term operating leases, which were not recorded on the consolidated balance sheets, were $74.2 million and $79.1 million , respectively, which is an estimate of the effect to total assets and total liabilities that the new accounting standard would have as of those dates. We are currently evaluating the impact that this standard will have on our financial condition, results of operations, and cash flows. In May 2014, the FASB issued guidance (the effective date of which was later delayed) that outlines a single comprehensive model for accounting for revenue arising from contracts with customers, which supersedes most of the existing revenue recognition guidance. This guidance requires an entity to recognize revenue when it transfers 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 and also requires certain additional disclosures. The guidance is effective for interim and annual reporting periods that begin after December 15, 2017. Early adoption of the standard is permitted, but not before the original effective date of December 15, 2016. During the second quarter of 2016, the FASB issued additional revenue recognition guidance that clarifies how an entity identifies performance obligations related to customer contracts as well as the objectives of collectibility, sales and other taxes, non-cash consideration, contract modifications at transition, and technical corrections. The guidance is effective beginning in the first quarter of 2018, and we do not currently plan to early adopt the guidance. The guidance permits two methods of adoption, retrospectively to each prior reporting period presented (full retrospective method), or retrospectively with the cumulative effect of initially applying the guidance recognized at the date of initial application (modified retrospective method). We have not yet selected a transition method, and we continue to evaluate the effect that the updated standard will have on our consolidated financial condition, results of operations and cash flows; however, we do not expect adoption of the guidance to have a material impact on our financial results. We primarily earn our revenue by producing and delivering ready-mixed concrete, aggregates, and related building materials, as requested by our customers primarily through purchase orders. We generally do not have significant customer contracts and do not provide post-delivery services, such as paving or finishing. As such, adoption of the new guidance should not result in significant changes in the amount of revenue recognized or the timing of when such revenue is recognized.
