Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Note 2 . Summary of Significant Accounting Policies Basis of Presentation and Consolidation The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with generally accepted a ccounting principles in the United States (“GAAP”) and applicable rules and regulations of the U.S. Securities and Exchange Commission (the “SEC”) regarding interim financial reporting. Certain information and note disclosures normally included in the financial statements prepared in accordance with GAAP have been condensed or omitted pursuant to such rules and regulations. As such, the information included in these unaudited interim financial statements and condensed notes should be read in conjunction with the Company’s The condensed consolidated balance sheet as of December 31, 2019 included herein has been derived from the Company’s audited financial statements as of that date, but does not include all disclosures including notes required by GAAP. The condensed consolidated financial statements include the accounts of SIC, its wholly owned subsidiaries, RDS and ASG, and their respective wholly-owned subsidiaries, and are presented in accordance with GAAP. All significant intercompany accounts and transactions have been eliminated in combination. References to the “ASC” hereafter refer to the Accounting Standards Codification established by the Financial Accounting Standards Board (“FASB”) as the source of authoritative GAAP. The accompanying condensed consolidated financial statements reflect all normal recurring adjustments necessary to present fairly the financial position, results of operations, and cash flows for the interim periods, but are not necessarily indicative of the results of operations to be anticipated for the full year ending December 31, 2020. There have been no changes to our significant accounting policies described in our consolidated financial statements and related disclosures as of December 31, 2019 that have had a material impact on our condensed consolidated financial statements and related notes. Earnings (Loss) per Share of Common Stock Basic earnings (loss) per share for the three and six months ended June 30, 2020 and 2019 are computed by dividing net income (loss) by the weighted average number of shares of common stock outstanding. Diluted earnings per share for common stock is computed by dividing net income by the weighted average number of shares of common stock outstanding plus the dilutive effect of restricted stock-based awards using the treasury stock method. The following table sets forth the computation of basic and diluted earnings/(loss) per share for the three and six months ended June 30, 2020 and 2019: Three Months Ended Three Months Ended (in thousands, except share data) June 30, 2020 June 30, 2019 Net income (loss) $ (3,179 ) $ 1,162 Weighted average shares of common stock outstanding: Basic common stock outstanding 25,328,649 25,289,041 Diluted common stock outstanding 25,328,649 25,383,843 Earnings (loss) per share of common stock: Basic common stock outstanding $ (0.13 ) $ 0.05 Diluted common stock outstanding $ (0.13 ) $ 0.05 Six Months Ended Six Months Ended (in thousands, except share data) June 30, 2020 June 30, 2019 Net income (loss) $ (7,181 ) $ 1,289 Weighted average shares of common stock outstanding: Basic common stock outstanding 25,260,425 25,526,332 Diluted common stock outstanding 25,260,425 25,603,663 Earnings (loss) per share of common stock: Basic common stock outstanding $ (0.28 ) $ 0.05 Diluted common stock outstanding $ (0.28 ) $ 0.05 All restricted stock awards outstanding consisting of 2,067,202 shares of restricted stock at June 30, 2020 were excluded from the computation of diluted earnings per share in the three and six months ended June 30, 2020 because the Company reported a net loss and the effect of inclusion would have been antidilutive. Use of Estimates The preparation of consolidated financial statements in accordance with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, contingencies, and reported revenues and expenses as of and for periods ended on the date of the consolidated financial statements. Actual results may vary materially from the estimates that were used. The Company’s significant accounting estimates include the determination of allowances for doubtful accounts, the lives and methods for recording depreciation and amortization on property and equipment, the fair value of reporting units and indefinite life intangible assets, deferred income taxes and the purchase price allocations used in the Company’s acquisitions. Fair Value Measurement ASC 820-10 requires entities to disclose the fair value of financial instruments, both assets and liabilities recognized and not recognized on the balance sheet for which it is practicable to estimate fair value. ASC 820-10 defines the fair value of a financial instrument as the amount at which the instrument could be exchanged in a current transaction between willing parties. The three levels of the fair value hierarchy are as follows: Level 1—Valuations based on unadjusted quoted prices in active markets for identical assets or liabilities that the entity has the ability to access. Level 2—Valuations based on 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 data for substantially the full term of the assets or liabilities. Level 3—Valuations based on inputs that are unobservable, supported by little or no market activity and that are significant to the fair value of the assets or liabilities. The level of the fair value hierarchy in which the fair value measurement falls is determined by the lowest level input that is significant to the fair value measurement. The Company records contingent consideration, or earn-outs, associated with certain acquisitions. These earn-outs are adjusted to fair value at each reporting period and any change to fair value based on a change in certain factors, such as the discount rate or estimates for the outcome of specified milestone goals, will result in an adjustment to the fair value of the liability. These adjustments will be recorded to (income) expense as a measurement period adjustment. The earn-out liability associated with the acquisition of Summit Stoneworks, LLC (“Summit”) in August 2018 was reduced to zero as of December 31, 2019 and is no longer a Level 3 fair value estimate as the underlying inputs are now known and the earn-out target criteria were not met. Adjustments reducing the fair value of the earn-out liability by $0.5 million and $1.9 million were recorded within other (income) expense for the three and six months ended June 30, 2019, respectively. The earn-out liability associated with the acquisition of T.A.C. Ceramic Tile Co, LLC (“TAC”) in December 2018 was reduced to zero as of December 31, 2019 and is no longer a Level 3 fair value estimate as the underlying inputs are now known and the earn-out target criteria were not met. Adjustments increasing the fair value of the earn-out liability by $1.5 million and $1.2 million were recorded within other (income) expense for the three and six months ended June 30, 2019, respectively. The earn-out liability associated with the acquisition of Intown Design, Inc., Intown Granite of Charlotte, Inc., and Granitec, LLC, (collectively, “Intown”) At June 30, 2020 and December 31, 2019, the carrying value of the Company’s cash, accounts receivable, accounts payable, and short-term obligations approximate their respective fair values because of the short maturities of these instruments. The recorded values of the line of credit, term loans, and notes payable approximate their fair values, as interest rates approximate market rates. There were no transfers within Level 3 fair value measurements during the three months ended June 30, 2020. There were no transfers during the six months ended June 30, 2020, other than the Intown earn-out liability out of Level 3 due to the availability of observable and known inputs to calculate the fair value of the liability as of June 30, 2020. Intangible Assets Intangible assets consist of customer relationships, trade names and non-compete agreements. The Company considers all its intangible assets to have definite lives, and such intangible assets are being amortized on the straight-line method over the estimated useful lives of the respective assets or on an accelerated basis based on the expected cash flows generated by the existing customers as follows: Range of estimated useful lives Weighted average useful life Customer relationships 2 years – 15 years 10 years Trade names 3 years – 11 years 8 years Non-compete agreements Life of agreement 4 years Business Combinations The Company records business combinations using the acquisition method of accounting. Under the acquisition method of accounting, identifiable assets acquired and liabilities assumed are recorded at their acquisition date fair values. The excess of the purchase price over the estimated fair value is recorded as goodwill. The measurement period remains open pending the completion of valuation procedures related to the acquired assets and assumed liabilities. Measurement period adjustments are reflected in the period in which they occur. Impairment of Long-Lived Assets The Company reviews the recoverability of its long-lived assets, such as property and equipment and intangible assets, whenever events or changes in circumstances occur that indicate the carrying value of the asset or asset group may not be recoverable, or at least annually. The assessment for possible impairment is based on the Company’s ability to recover the carrying value of the asset or asset group from the expected future undiscounted cash flows of the related operations. If the aggregate of these cash flows is less than the carrying value of such assets, an impairment loss is recognized for the difference between the estimated fair value and the carrying value. The measurement of impairment requires management to estimate future cash flows and the fair value of long-lived assets. There were no impairment losses on long-lived assets for the six-month period ended June 30, 2020 or the year ended December 31, 2019. Goodwill Goodwill represents the excess of the cost of an acquired entity over the fair value of the acquired net assets, including intangible assets. Goodwill is tested annually for impairment on December 31. Impairment indicators existed as of March 31, 2020 surrounding the decrease in the Company’s stock price, significant adverse changes in the business climate and other macroeconomic conditions. The Company performed a goodwill impairment test as of March 31, 2020. The Company identified RDS and ASG as reporting units and determined each reporting unit’s fair value exceeded such reporting unit’s carrying value. No additional impairment indicators were identified during the three months ended June 30, 2020. There were no impairment charges related to goodwill for the six months ended June 30, 2020 or the year ended December 31, 2019. Revenue Recognition The Company’s revenue derived from the sale of imported granite, marble, and related items, primarily in our ASG operating segment, is recognized at a point in time when control over a product is transferred to a customer. This transfer occurs primarily when goods are picked up by a customer at the branch or when goods are delivered to a customer location. The Company’s contracts with its home builder customers within our RDS operating segment are usually short-term in nature and will generally range in length from several days to several weeks. The Company’s contracts related to multi-family and commercial projects are generally long-term in nature. We recognize revenue from both short-term and long-term contracts for each distinct performance obligation identified over time on a percentage-of-completion basis of accounting, utilizing the output method as a measure of progress, as we believe this represents the best measure of when goods and services are transferred to the customer. Revenue is measured at the transaction price, which is based on the amount of consideration the Company expects to receive in exchange for transferring the promised goods or services to the customer. The transaction price includes estimates of variable consideration, such as any returns and sales incentives. Applicable customer sales taxes, when remitted, are recorded as a liability and excluded from revenue on a net basis. Customer payments may be due in advance of contract work performed, at the time the performance obligation is completed, or with payment terms following performance completion of generally 30-60 days. In the fourth quarter of 2019, the Company adopted ASU 2014-09, the new accounting standard under ASC Topic 606, using the modified retrospective method as of January 1, 2019. The results for the three and six months ended June 30, 2019 have not been adjusted to reflect the adoption of ASU 2014-09. (See Note 3 Shipping and Handling Charges Fees charged to customers for shipping and handling of product are included in revenues. The costs for shipping and handling of product are recorded as a component of cost of revenue. Additionally, we consider shipping and handling costs charged to a customer as a fulfillment cost rather than a promised service and expense as incurred. Equity-based Compensation The Company accounts for equity-based awards by measuring the awards at the date of grant and recognizing the grant-date fair value as an expense using either straight-line or accelerated attribution, depending on the specific terms of the award agreements over the requisite service period, which is usually equivalent to the vesting period. See Note 12 Segment Reporting In accordance with ASC 280-10-50-1, an operating segment is a component of an entity that has all of the following characteristics: a. It engages in business activities from which it may earn revenues and incur expenses; b. Its discrete financial information is available; and c. Its operating results are regularly reviewed by the public entity’s chief operating decision maker to make decisions about resources to be allocated to the segment and assess its performance. The Company has identified two operating segments that meet all three of the above criteria, RDS and ASG. Each of these operating segments provides products and services that generate revenue and incur expenses as it engages in business activities, and each maintains discrete financial information. Additionally, the Company’s chief operating decision maker, its Chief Executive Officer, reviews financial performance, approves budgets and allocates resources at each of the RDS and ASG operating segment levels. Recently Issued and Adopted Accounting Pronouncements The Company is an “emerging growth company,” as defined in Section 2(a) of the Securities Act, as modified by the Jumpstart Our Business Startups Act of 2012 (the “JOBS Act”). The JOBS Act permits emerging growth companies to take advantage of an extended transition period to comply with new or revised accounting standards applicable to public companies. The Company has elected to use the extended transition period for complying with new or revised accounting standards under Section 107 of the JOBS Act. This election allows the Company to delay the adoption of new or revised accounting standards that have different effective dates for public and private companies until those standards apply to private companies.

ASU 2018-15 provides additional guidance on the accounting for costs of implementation activities performed in a cloud computing arrangement that is a service contract. The amendments in ASU 2018-15 align the requirements for capitalizing implementation costs incurred in a hosting arrangement that is a service contract with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use software (and hosting arrangements that include an internal use software license). Costs for implementation activities in the application development stage are capitalized depending on the nature of the costs, while costs incurred during the preliminary project and post implementation stages are expensed as the activities are performed. ASU 2018-15 is effective for fiscal years beginning after December 15, 2020. Early adoption of the amendments in ASU 2018-15 is permitted, including adoption in any interim period, for all entities. The amendments in ASU 2018-15 should be applied either retrospectively or prospectively to all implementation costs incurred after the date of adoption. The Company is currently assessing the effect this guidance may have on its consolidated financial statements. In December 2019, the FASB issued ASU 2019-12, “ Simplifying the Accounting for Income Taxes

Revenue From Contract With Customer [Abstract]
Revenue	Note 3. Revenue The Company’s revenue derived from the sale of imported granite, marble, and related items, primarily in our ASG operating segment, is recognized at a point in time when control over a product is transferred to a customer. This transfer occurs primarily when goods are picked up by a customer at the branch or when goods are delivered to a customer location. The Company’s contracts with its home builder customers within our RDS operating segment are usually short-term in nature and will generally range in length from several days to several weeks. The Company’s contracts related to multi-family and commercial projects are generally long-term in nature. The Company recognizes revenue from both short-term and long-term contracts for each distinct performance obligation identified over time on a percentage-of-completion basis of accounting, utilizing the output method as a measure of progress, as the Company believes this represents the best measure of when goods and services are transferred to the customer. In the fourth quarter of 2019, the Company adopted ASU 2014-09, the new accounting standard under ASC Topic 606, using the modified retrospective method as of January 1, 2019. The results for the three and six months ended June 30, 2019 have not been adjusted to reflect the adoption of ASU 2014-09. The impact of adoption of ASU 2014-09 was not material and was less than $0.2 million to net revenue for both the three and six months ended June 30, 2020. Contract Balances The timing of revenue recognition, billings, and cash collections results in billed accounts receivable, revenue in excess of billings, customer deposits, and billings in excess of revenue recognized in the Company’s Consolidated Balance Sheets. Contract assets The Company’s contract assets consist of unbilled amounts typically resulting from sales under contracts when the revenue recognized exceeds the amount billed to the customer, generally in the RDS operating segment revenues derived from homebuilders and commercial and multifamily projects. Contract assets are recorded in other current assets in the . The Company had contract assets of $10.2 million and $5.7 million as of June 30, 2020 and December 31, 2019, respectively. The Company’s contract assets generally become unconditional and are reclassified to receivables in the quarter subsequent to each balance sheet date. Contract liabilities The Company records contract liabilities when it receives payment prior to fulfilling a performance obligation or has billings in excess of revenue recognized Company’s Consolidated Balance Sheets Remaining Performance Obligations Remaining performance obligations related to ASC 606 represent the aggregate transaction price allocated to performance obligations with an original contract term greater than one year which are fully or partially unsatisfied at the end of the period, and relate primarily to multi-family or commercial revenue. For the six months ended June 30, 2020 and 2019, multi-family and commercial projects accounted for approximately 3.0% and 2.6% of the Company’s consolidated revenues, respectively. For the three months ended June 30, 2020 and 2019, multi-family and commercial projects accounted for approximately 3.2% and 3.3% of the Company’s consolidated revenues, respectively.

The purchase agreement also provides for potential earn-out consideration to the former shareholders of Intown in connection with the achievement of certain 2019 and 2020 financial milestones. The final earn-out payment has no maximum limit, but if certain targets are not met, there may be no earn-out payment. The contingent earn-out consideration had an estimated purchase price fair value of $2.0 million as of March 31, 2019. The upfront cash paid for the Intown acquisition was financed with additional borrowings from the Company’s third-party financing agreement described in Note 10. (in thousands) Amount Cash consideration $ 11,537 Fair value of earn-out 2,010 $ 13,547 RDS acquired Intown to further diversify RDS’ geographic mix and channel strength. The goodwill recorded reflects the strategic value of the acquisition beyond the net value of its assets acquired less liabilities assumed. Goodwill of $0.1 million is deductible for tax purposes. The Company incurred approximately $0.4 million in direct acquisition costs, all of which were expensed as incurred, and are included in general and administrative expenses in the consolidated statements of operations. The Company has performed a valuation of the acquired assets and assumed liabilities of Intown. Using the total consideration for the acquisition, the Company has performed an allocation of such assets and liabilities.

Lines of Credit SIC Line of Credit In June 2018, the Company and certain of its subsidiaries entered into an amended and restated loan, security and guaranty agreement, dated as of June 28, 2018, which was amended on December 11, 2018, July 23, 2019 and August 19, 2019 (“SIC Credit Facility”), with a commercial bank, which amended and restated each of the RDS credit agreement and the ASG credit agreement in their entirety. The SIC Credit Facility will be used by the Company, including both RDS and ASG, for operational purposes. Pursuant to the SIC Credit Facility, the Company has a borrowing-base-governed revolving credit facility that provides for borrowings in an initial amount up to an aggregate of $90 million, which was increased to $100 million through the amendment entered into on August 19, 2019. Under the terms of the SIC Credit Facility, the Company has the ability to request the issuance of letters of credit up to a maximum aggregate stated amount of $15 million. The ability to borrow revolving loans under the SIC Credit Facility is reduced on a dollar-for-dollar basis by the aggregate stated amount of all outstanding letters of credit. The indebtedness outstanding under the SIC Credit Facility is secured by substantially all of the assets of the Company and its subsidiaries. The revolving loans under the SIC Credit Facility bear interest at a floating rate, which the Company can elect between a LIBOR based rate plus an applicable margin varying from one hundred twenty five basis points (1.25%) to one hundred seventy five basis points (1.75%) based on the borrowers’ average daily availability determined quarterly, or a base rate (determined as the greatest of the Prime rate, the Federal Funds rate plus a fifty basis point (0.50%) margin, or the LIBOR rate with a 30 day interest period plus a two hundred basis point (2.00%) margin) plus an applicable margin varying from twenty five basis points (0.25%) to seventy five basis points (0.75%) based on the borrowers’ average daily availability determined quarterly. Upon the occurrence of certain events of default under the SIC Credit Facility, the interest rate applicable to the obligations thereunder may be increased by two hundred basis points (2.00%). All revolving loans under the SIC Credit Facility are due and payable in full on June 28, 2023, subject to earlier acceleration upon certain conditions. Letter of credit obligations under the SIC Credit Facility are due and payable on the date set forth in the respective loan documents or upon demand by the lender. Under the SIC Credit Facility, the Company and its subsidiaries are required to comply with certain customary restrictive covenants that, among other things and with certain exceptions, limit the ability of the Company and its subsidiaries, as applicable, to (i) incur additional indebtedness and liens in connection therewith, (ii) pay dividends and make certain other restricted payments, (iii) effect mergers or consolidations, (iv) enter into transactions with affiliates, (v) sell or dispose of property or assets, and (vi) engage in unrelated lines of business. As of June 30, 2020 and December 31, 2019, $9.6 million and $22.2 million, respectively, were outstanding under the SIC Credit Facility. The Company also has $0.4 million in letters of credit outstanding at June 30, 2020. The SIC Credit Facility is subject to certain financial covenants. At June 30, 2020, the Company was in compliance with the financial covenants. The Company incurred debt issuance costs of $0.5 million in connection with the SIC Credit Facility. These costs are amortized to non-cash interest expense over the term of the agreement on a straight-line basis which approximates the effective interest method. Non-cash interest expense related to these costs were less than $0.1 million for the three and six months ended June 30, 2020 and 2019. At June 30, 2020 and December 31, 2019, SIC had $0.3 million of unamortized debt issuance costs related to the SIC Credit Facility.

In the event the leverage ratio is less than 2.40:1.00, the rates decrease to either (i) the base rate plus 4.25% for a base rate loan or (ii) the LIBOR rate plus 6.25% for a LIBOR loan. The base rate is the greater of (i) the publicly announced interest rate by the reference bank as its reference rate, the base commercial lending rate or prime rate, and (ii) 3.5% per annum. The interest rate assessed as of June 30, 2020 was 7.5%. Substantially all of the Company’s assets, including accounts receivable and inventory, are collateral for the Term Loan Facility, except assets identified as collateral for the SIC Credit Facility which hold a senior position. The Company is also restricted from paying dividends to its stockholders. Additionally, substantially all of the Company’s subsidiaries are restricted by the Term Loan Facility from providing loans, advances and dividends to the SIC parent company. The Company is required to meet certain covenants pursuant to these term loans. The Company was in compliance with all financial covenants as of June 30, 2020 and December 31, 2019.

The leased vehicles are included as property and equipment (“PP&E”) and amortized to accumulated amortization on a straight-line basis over the life of the lease, which is typically four years. The total acquisition cost included in PP&E related to the leased vehicles was $11.8 million and $11.2 million at June 30, 2020 and December 31, 2019, respectively. Total accumulated amortization related to the leased vehicles is $2.4 million and $1.6 million at June 30, 2020 and December 31, 2019, respectively. Amortization expense was $0.5 million and $0.8 million for the three and six months ended June 30, 2020. Amortization expense was $0.1 million and $0.3 million for the three and six months ended June 30, 2019. Included in the capital lease balances is approximately $3.1 million of assets that were sold and subsequently leased back during 2019 and in the first quarter of 2020 related to certain ERP software and equipment. The transaction did not qualify for sale-leaseback accounting and no sale was recognized. Proceeds received in the first quarter of 2020 from the transaction were reported as a financing activity in the statement of cash flows for the six months ended June 30, 2020. RDS leases its corporate, administrative, fabrication and warehousing facilities under long-term non-cancelable operating lease agreements expiring at various dates through November 2024. The monthly rents are subject to annual increases and generally require the payment of utilities, real estate taxes, insurance and repairs. Three of RDS’ facility leases are with a company owned by a Company stockholder and five other facilities are leased from current employees or contractors. RDS also leases certain office equipment under long-term lease agreements expiring at various dates through September 2022. ASG leases its facilities and equipment under long-term non-cancellable operating lease agreements expiring at various dates through December 2029. The facility leases contain predetermined fixed escalations of the minimum rentals. One of ASG’s facility leases is with a related party. SIC leases its corporate facilities under a long-term non-cancelable operating lease through October 2022. The Company recognizes rent expense on a straight-line basis and records the difference between the recognized rent expense and amounts payable under the lease as deferred rent. Aggregate deferred rent at June 30, 2020 and December 31, 2019 was $2.3 million and $2.2 million, respectively. Aggregate rent expense for the three and six months ended June 30, 2020 totaled $5.3 million and $10.3 million, respectively. Aggregate rent expense for the three and six months ended June 30, 2019 totaled $4.7 million and $9.4 million, respectively. Litigation The Company experiences routine litigation in the normal course of its business. Production residential builders in California are primarily sued for alleged construction defects. As a practice, residential builders name all Indemnification In the normal course of business, the Company enters into contracts and agreements that contain a variety of representations and warranties and provide for general indemnifications, including to lessors of office and warehouse space for certain actions arising during the Company’s tenancy and to the Company’s customers. The Company’s exposure under these agreements is unknown because it involves claims that may be made against the Company in the future but have not yet been made. To date, the Company has not paid any claims or been required to defend any action related to its indemnification obligations. However, the Company may record charges in the future as a result of these indemnification obligations. Exclusive Distributor Rights A main quartz supplier of ASG’s Pental business has granted ASG exclusive distribution rights in 23 states in the United States. To maintain these rights, ASG must meet certain minimum purchase requirements. For the remainder of 2020, ASG is required to purchase 540 containers during both the three months ended September 30, 2020 and December 31, 2020. Minimum purchase volumes then increase to 645 containers per quarter during 2021 up to 1,332 containers per quarter during 2025. Using an estimated price per container based on the average price per container in 2019, the future minimum purchases to maintain the exclusive rights as of June 30, 2020 are as follows: (in thousands) Amount Remaining in 2020 $ 37,417 2021 89,384 2022 108,093 2023 128,880 2024 153,824 2025 184,589 $ 702,187 If ASG does not purchase at least eighty percent (80%) of the minimum purchase volumes for two consecutive quarters, or at least ninety percent (90%) of the minimum purchase volumes in any calendar year, the supplier has the right to terminate ASG’s exclusive distribution rights. There are no financial penalties to ASG if such commitments are not met; however, the supplier reserves the right to terminate the exclusive distribution rights. For the two quarters ended June 30, 2020, ASG did not meet the eighty percent (80%) minimum purchase volume threshold in light of the current economic environment. ASG and the supplier have discussed the impact of the current economic environment on the minimum purchase volumes and have reached an informal understanding around reduced purchase volumes for the remainder of the year. The supplier must give 60 days notice to terminate this exclusivity arrangement, which has not been received by the Company. While ASG maintains good relationships with this supplier and believes that it would be unlikely that such supplier would terminate the exclusive relationship, there is no guarantee that such supplier will not terminate the exclusive relationship in the future due to ASG’s failure to purchase the minimum volumes. In the event the supplier were to terminate ASG’s distribution rights it could have a material impact on ASG’s supply chain and ASG may be unable to find an alternative source for quartz in a timely manner or on favorable terms. Purchase Commitments The Company also has contracted to minimum purchase commitments with certain suppliers. RDS has committed to purchase $2.0 million in products annually for each of the calendar years 2020 and 2021 with a certain supplier. The minimum purchase commitment for the year 2020 has been achieved during the six months ended June 30, 2020. Financial penalties for not achieving the minimum purchase commitment amount are equal to 15% of the shortfall amount. In addition, ASG has committed to purchase approximately $0.4 million, based on current prices, worth of materials from a supplier by the end of 2020.

Disclosure Of Compensation Related Costs Sharebased Payments [Abstract]
Stock Compensation	Note 12 . Stock Compensation On November 22, 2017, the Company adopted the Select Interior Concepts, Inc. 2017 Incentive Compensation Plan (the “2017 Plan”). Upon the adoption of the 2017 Plan, the maximum aggregate number of shares issuable thereunder was 2,561,463 shares. As of June 30, 2020, there were 1,067,202 shares of the Company’s common stock subject to outstanding awards and 808,040 shares of the Company’s common stock were reserved and available for future awards under the 2017 Plan. On March 26, 2019, the board of directors adopted the Select Interior Concepts, Inc. 2019 Long-Term Incentive Plan (the “2019 Incentive Plan”), which was approved at the 2019 Annual Meeting of Stockholders on May 15, 2019. The 2019 Incentive Plan serves as the successor to the 2017 Plan; however, shares continued to be available for award grants under the 2017 Plan following the effectiveness of the 2019 Incentive Plan. The maximum aggregate number of shares issuable under the 2019 Incentive Plan is 1,700,000. No awards had been issued under the 2019 Incentive Plan as of June 30, 2020. The 2017 Plan and the 2019 Incentive Plan (collectively, “the Plans”), permit the grant of incentive stock options to employees and the grant of nonstatutory stock options, performance awards, restricted stock, restricted stock units, stock appreciation rights, and other stock-based awards to the Company’s employees, directors and consultants at the sole discretion of the Company’s Compensation Committee of the board of directors. Stock Options The Company has not granted any stock options under the Plans. Restricted Stock and Restricted Stock Units Restricted stock awards and restricted stock unit awards are grants of shares of the Company’s common stock or rights to receive shares of the Company’s common stock that are subject to various restrictions, including restrictions on transferability, vesting and forfeiture provisions. Recipients of restricted stock awards generally will have voting and dividend rights with respect to such shares prior to vesting, subject to such awards’ forfeiture provisions, unless the board of directors provides otherwise. Recipients of restricted stock unit awards generally will not have voting and dividend rights unless and until shares of common stock are issued with respect to such awards. Shares of restricted stock that do not vest for any reason will be forfeited by the recipient and will revert to the Company. For the six months ended June 30, 2020, 376,720 restricted stock units were granted under the 2017 Plan to certain executives and key employees. Certain of these restricted stock units included a market condition under ASC 718 “Compensation – Stock Compensation.” During the three months ended March 31, 2019, restricted stock units were granted to certain executives and include both a service and a performance condition. The performance condition is achievement of a 2021 earnings target and the level of achievement of the earnings target determines the number of shares that will be issued. The number of shares to be issued at achievement of 100% of the earnings target is 573,824, and up to 1,147,648 shares will be issued upon achievement of 200% of the earnings target. The 200% target share amount of 1,147,648 were included as granted in the January 1, 2020, figure in the table below of nonvested shares outstanding. In the first quarter of 2020, the performance condition for these shares that was deemed probable of vesting as of December 31, 2019 was determined to be no longer probable of vesting. This resulted in a reversal of stock compensation expense of approximately $1.6 million recorded during the three months ended March 31, 2020. No impact from the reversal of the stock compensation expense was recorded during the three months ended June 30, 2020. In connection with the appointment of L. W. Varner, Jr. as the new Chief Executive Officer of the Company in June 2020, Mr. Varner received a one-time grant of 500,000 time-based restricted stock units and 500,000 performance-based restricted stock units. The restricted stock units were granted as inducement awards in accordance with NASDAQ Listing Rule 5635(c)(4) and were not granted under the Plans. The time-based restricted stock units vest in equal annual installments over four years, subject to Mr. Varner’s continued employment with the Company. The performance-based restricted stock units contain market conditions based on the closing price of the Company’s common stock exceeding specific price hurdles for 20 consecutive trading days, and subject to Mr. Varner’s continued employment with the Company. The Company estimated the fair value of all shares granted on the date the shares were granted and recognizes the resulting fair value over the requisite service period. The grant date fair value for the restricted stock units issued during the six months ended June 30, 2020 was determined using the closing share price on the date of grant. For shares issued with a market condition, the Monte Carlo simulation model was used to determine the fair value of the award. Inputs into the Monte Carlo simulation model for applicable awards during the six months ended June 30, 2020 included a dividend yield of 0%, an expected volatility rate ranging from 48.06% to 51.95%, and a risk-free rate ranging from 0.19% to 0.37%. A summary of the Company’s restricted stock activity for the six months ended June 30, 2020 is as follows: Nonvested Shares Outstanding Weighted Average Grant Date Fair Value Nonvested shares at January 1, 2020 1,825,123 $ 12.75 Granted 1,376,720 $ 3.79 Forfeited 773,334 $ 11.52 Vested 361,307 $ 10.78 Nonvested shares at June 30, 2020 2,067,202 $ 7.64 As of June 30, 2020, total remaining stock-based compensation expense for nonvested restricted stock units is $7.4 million, which is expected to be recognized over a weighted average remaining period of 2.7 years. Total stock-based compensation expense recognized for restricted stock units for the three and six months ended June 30, 2020 was $1.2 million and $0.6 million, respectively. Total stock-based compensation expense recognized for restricted stock units for the three and six months ended June 30, 2019 was $1.4 million and $2.0 million, respectively. Phantom Stock Phantom stock awards are grants of phantom stock with respect to shares of the Company’s common stock that are settled in cash and subject to various restrictions, including restrictions on transferability, vesting and forfeiture provisions. Shares of phantom stock that do not vest for any reason will be forfeited by the recipient and will revert to the Company. The Company recorded phantom stock-based compensation expense of less than $0.01 million during the three and six months ended June 30, 2020 and 2019. There were 694 outstanding phantom shares as of December 31, 2019 and June 30, 2020. As of June 30, 2020, total remaining stock-based compensation expense for phantom stock is less than $0.01 million, which is expected to be recognized over a weighted average remaining period of 0.5 years.

Provision for Income Taxes

Income Tax Disclosure [Abstract]
Provision for Income Taxes	Note 13. Provision for Income Taxes The Company determines its periodic income tax benefit or expense based upon the current period income and the annual estimated tax rate for the Company adjusted for discrete items. The estimated tax rate is revised, if necessary, as of the end of each successive interim period during the fiscal year to the Company’s current annual estimated tax rate. For the six months ended June 30, 2020, the effective tax rate of 34.00% increased compared to the effective tax rate of 33.10% for the six months ended June 30, 2019, due to the impact of discrete items in relation to the amount of the Company’s pre-tax earnings. The discrete items include unfavorable adjustments resulting from ASU 2016-09, which requires excess tax benefits and deficiencies related to stock compensation to be recognized as a component of income tax expense rather than stockholders’ equity, in addition to unrecognized tax benefits related to the TAC acquisition. In response to the global impacts of COVID-19 on U.S. companies and citizens, the federal government enacted the CARES Act on March 27, 2020. The CARES Act included several temporary tax relief provisions for companies, including modifications to the interest deduction limitation and a five-year net operating loss carryback. In response to these tax relief provisions, the Company has adjusted its deferred tax asset related to the interest limitation and anticipates carrying back any net operating loss generated in 2020 to prior tax periods.

Segment Information	Jun. 30, 2020
Segment Reporting [Abstract]
Segment Information	Note 15. Segment Information The Company’s operations are classified into two operating segments: RDS and ASG. Under RDS, the Company offers interior design and installation services, and under ASG, the Company offers natural and engineered surfaces distribution services. These operating segments represent strategic business areas which, although they operate separately and provide their own distinctive services, enable the Company to more effectively offer the complete line of interior design and selection services, merchandising, and complex supply chain management. Neither of the two operating segments have any reporting units. While individual acquisitions, for a time, may have discrete financial information before being fully integrated, RDS and ASG are the only operating and reporting segments for which both discrete financial information is available and is reviewed by the Company’s chief operating decision maker. Inter-segment eliminations result, primarily, from the sale of ASG inventory to the RDS segment, including the related profit margin, as well as some intercompany borrowings recorded in the form of intercompany payables and receivables. In addition, certain corporate-level costs incurred at a corporate level or at the reporting unit level that benefit the segments are not allocated. These costs include: corporate payroll costs, legal, professional service fees, interest expense, including amortization of deferred financing costs, and taxes and equity-based compensation.

Summary of Significant Accounting Policies (Policies)	Jun. 30, 2020
Accounting Policies [Abstract]
Basis of Presentation and Consolidation	Basis of Presentation and Consolidation The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with generally accepted a ccounting principles in the United States (“GAAP”) and applicable rules and regulations of the U.S. Securities and Exchange Commission (the “SEC”) regarding interim financial reporting. Certain information and note disclosures normally included in the financial statements prepared in accordance with GAAP have been condensed or omitted pursuant to such rules and regulations. As such, the information included in these unaudited interim financial statements and condensed notes should be read in conjunction with the Company’s The condensed consolidated balance sheet as of December 31, 2019 included herein has been derived from the Company’s audited financial statements as of that date, but does not include all disclosures including notes required by GAAP. The condensed consolidated financial statements include the accounts of SIC, its wholly owned subsidiaries, RDS and ASG, and their respective wholly-owned subsidiaries, and are presented in accordance with GAAP. All significant intercompany accounts and transactions have been eliminated in combination. References to the “ASC” hereafter refer to the Accounting Standards Codification established by the Financial Accounting Standards Board (“FASB”) as the source of authoritative GAAP. The accompanying condensed consolidated financial statements reflect all normal recurring adjustments necessary to present fairly the financial position, results of operations, and cash flows for the interim periods, but are not necessarily indicative of the results of operations to be anticipated for the full year ending December 31, 2020. There have been no changes to our significant accounting policies described in our consolidated financial statements and related disclosures as of December 31, 2019 that have had a material impact on our condensed consolidated financial statements and related notes.
Earnings (Loss) per Share of Common Stock	Earnings (Loss) per Share of Common Stock Basic earnings (loss) per share for the three and six months ended June 30, 2020 and 2019 are computed by dividing net income (loss) by the weighted average number of shares of common stock outstanding. Diluted earnings per share for common stock is computed by dividing net income by the weighted average number of shares of common stock outstanding plus the dilutive effect of restricted stock-based awards using the treasury stock method. The following table sets forth the computation of basic and diluted earnings/(loss) per share for the three and six months ended June 30, 2020 and 2019: Three Months Ended Three Months Ended (in thousands, except share data) June 30, 2020 June 30, 2019 Net income (loss) $ (3,179 ) $ 1,162 Weighted average shares of common stock outstanding: Basic common stock outstanding 25,328,649 25,289,041 Diluted common stock outstanding 25,328,649 25,383,843 Earnings (loss) per share of common stock: Basic common stock outstanding $ (0.13 ) $ 0.05 Diluted common stock outstanding $ (0.13 ) $ 0.05 Six Months Ended Six Months Ended (in thousands, except share data) June 30, 2020 June 30, 2019 Net income (loss) $ (7,181 ) $ 1,289 Weighted average shares of common stock outstanding: Basic common stock outstanding 25,260,425 25,526,332 Diluted common stock outstanding 25,260,425 25,603,663 Earnings (loss) per share of common stock: Basic common stock outstanding $ (0.28 ) $ 0.05 Diluted common stock outstanding $ (0.28 ) $ 0.05 All restricted stock awards outstanding consisting of 2,067,202 shares of restricted stock at June 30, 2020 were excluded from the computation of diluted earnings per share in the three and six months ended June 30, 2020 because the Company reported a net loss and the effect of inclusion would have been antidilutive.
Use of Estimates	Use of Estimates The preparation of consolidated financial statements in accordance with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, contingencies, and reported revenues and expenses as of and for periods ended on the date of the consolidated financial statements. Actual results may vary materially from the estimates that were used. The Company’s significant accounting estimates include the determination of allowances for doubtful accounts, the lives and methods for recording depreciation and amortization on property and equipment, the fair value of reporting units and indefinite life intangible assets, deferred income taxes and the purchase price allocations used in the Company’s acquisitions.
Fair Value Measurement	Fair Value Measurement ASC 820-10 requires entities to disclose the fair value of financial instruments, both assets and liabilities recognized and not recognized on the balance sheet for which it is practicable to estimate fair value. ASC 820-10 defines the fair value of a financial instrument as the amount at which the instrument could be exchanged in a current transaction between willing parties. The three levels of the fair value hierarchy are as follows: Level 1—Valuations based on unadjusted quoted prices in active markets for identical assets or liabilities that the entity has the ability to access. Level 2—Valuations based on 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 data for substantially the full term of the assets or liabilities. Level 3—Valuations based on inputs that are unobservable, supported by little or no market activity and that are significant to the fair value of the assets or liabilities. The level of the fair value hierarchy in which the fair value measurement falls is determined by the lowest level input that is significant to the fair value measurement. The Company records contingent consideration, or earn-outs, associated with certain acquisitions. These earn-outs are adjusted to fair value at each reporting period and any change to fair value based on a change in certain factors, such as the discount rate or estimates for the outcome of specified milestone goals, will result in an adjustment to the fair value of the liability. These adjustments will be recorded to (income) expense as a measurement period adjustment. The earn-out liability associated with the acquisition of Summit Stoneworks, LLC (“Summit”) in August 2018 was reduced to zero as of December 31, 2019 and is no longer a Level 3 fair value estimate as the underlying inputs are now known and the earn-out target criteria were not met. Adjustments reducing the fair value of the earn-out liability by $0.5 million and $1.9 million were recorded within other (income) expense for the three and six months ended June 30, 2019, respectively. The earn-out liability associated with the acquisition of T.A.C. Ceramic Tile Co, LLC (“TAC”) in December 2018 was reduced to zero as of December 31, 2019 and is no longer a Level 3 fair value estimate as the underlying inputs are now known and the earn-out target criteria were not met. Adjustments increasing the fair value of the earn-out liability by $1.5 million and $1.2 million were recorded within other (income) expense for the three and six months ended June 30, 2019, respectively. The earn-out liability associated with the acquisition of Intown Design, Inc., Intown Granite of Charlotte, Inc., and Granitec, LLC, (collectively, “Intown”) At June 30, 2020 and December 31, 2019, the carrying value of the Company’s cash, accounts receivable, accounts payable, and short-term obligations approximate their respective fair values because of the short maturities of these instruments. The recorded values of the line of credit, term loans, and notes payable approximate their fair values, as interest rates approximate market rates. There were no transfers within Level 3 fair value measurements during the three months ended June 30, 2020. There were no transfers during the six months ended June 30, 2020, other than the Intown earn-out liability out of Level 3 due to the availability of observable and known inputs to calculate the fair value of the liability as of June 30, 2020.
Intangible Assets	Intangible Assets Intangible assets consist of customer relationships, trade names and non-compete agreements. The Company considers all its intangible assets to have definite lives, and such intangible assets are being amortized on the straight-line method over the estimated useful lives of the respective assets or on an accelerated basis based on the expected cash flows generated by the existing customers as follows: Range of estimated useful lives Weighted average useful life Customer relationships 2 years – 15 years 10 years Trade names 3 years – 11 years 8 years Non-compete agreements Life of agreement 4 years
Business Combinations	Business Combinations The Company records business combinations using the acquisition method of accounting. Under the acquisition method of accounting, identifiable assets acquired and liabilities assumed are recorded at their acquisition date fair values. The excess of the purchase price over the estimated fair value is recorded as goodwill. The measurement period remains open pending the completion of valuation procedures related to the acquired assets and assumed liabilities. Measurement period adjustments are reflected in the period in which they occur.
Impairment of Long-Lived Assets	Impairment of Long-Lived Assets The Company reviews the recoverability of its long-lived assets, such as property and equipment and intangible assets, whenever events or changes in circumstances occur that indicate the carrying value of the asset or asset group may not be recoverable, or at least annually. The assessment for possible impairment is based on the Company’s ability to recover the carrying value of the asset or asset group from the expected future undiscounted cash flows of the related operations. If the aggregate of these cash flows is less than the carrying value of such assets, an impairment loss is recognized for the difference between the estimated fair value and the carrying value. The measurement of impairment requires management to estimate future cash flows and the fair value of long-lived assets. There were no impairment losses on long-lived assets for the six-month period ended June 30, 2020 or the year ended December 31, 2019.
Goodwill	Goodwill Goodwill represents the excess of the cost of an acquired entity over the fair value of the acquired net assets, including intangible assets. Goodwill is tested annually for impairment on December 31. Impairment indicators existed as of March 31, 2020 surrounding the decrease in the Company’s stock price, significant adverse changes in the business climate and other macroeconomic conditions. The Company performed a goodwill impairment test as of March 31, 2020. The Company identified RDS and ASG as reporting units and determined each reporting unit’s fair value exceeded such reporting unit’s carrying value. No additional impairment indicators were identified during the three months ended June 30, 2020. There were no impairment charges related to goodwill for the six months ended June 30, 2020 or the year ended December 31, 2019.
Revenue Recognition	Revenue Recognition The Company’s revenue derived from the sale of imported granite, marble, and related items, primarily in our ASG operating segment, is recognized at a point in time when control over a product is transferred to a customer. This transfer occurs primarily when goods are picked up by a customer at the branch or when goods are delivered to a customer location. The Company’s contracts with its home builder customers within our RDS operating segment are usually short-term in nature and will generally range in length from several days to several weeks. The Company’s contracts related to multi-family and commercial projects are generally long-term in nature. We recognize revenue from both short-term and long-term contracts for each distinct performance obligation identified over time on a percentage-of-completion basis of accounting, utilizing the output method as a measure of progress, as we believe this represents the best measure of when goods and services are transferred to the customer. Revenue is measured at the transaction price, which is based on the amount of consideration the Company expects to receive in exchange for transferring the promised goods or services to the customer. The transaction price includes estimates of variable consideration, such as any returns and sales incentives. Applicable customer sales taxes, when remitted, are recorded as a liability and excluded from revenue on a net basis. Customer payments may be due in advance of contract work performed, at the time the performance obligation is completed, or with payment terms following performance completion of generally 30-60 days. In the fourth quarter of 2019, the Company adopted ASU 2014-09, the new accounting standard under ASC Topic 606, using the modified retrospective method as of January 1, 2019. The results for the three and six months ended June 30, 2019 have not been adjusted to reflect the adoption of ASU 2014-09. (See Note 3
Shipping and Handling Charges	Shipping and Handling Charges Fees charged to customers for shipping and handling of product are included in revenues. The costs for shipping and handling of product are recorded as a component of cost of revenue. Additionally, we consider shipping and handling costs charged to a customer as a fulfillment cost rather than a promised service and expense as incurred.
Equity-based Compensation	Equity-based Compensation The Company accounts for equity-based awards by measuring the awards at the date of grant and recognizing the grant-date fair value as an expense using either straight-line or accelerated attribution, depending on the specific terms of the award agreements over the requisite service period, which is usually equivalent to the vesting period. See Note 12
Segment Reporting	Segment Reporting In accordance with ASC 280-10-50-1, an operating segment is a component of an entity that has all of the following characteristics: a. It engages in business activities from which it may earn revenues and incur expenses; b. Its discrete financial information is available; and c. Its operating results are regularly reviewed by the public entity’s chief operating decision maker to make decisions about resources to be allocated to the segment and assess its performance. The Company has identified two operating segments that meet all three of the above criteria, RDS and ASG. Each of these operating segments provides products and services that generate revenue and incur expenses as it engages in business activities, and each maintains discrete financial information. Additionally, the Company’s chief operating decision maker, its Chief Executive Officer, reviews financial performance, approves budgets and allocates resources at each of the RDS and ASG operating segment levels.
Recently Issued and Adopted Accounting Pronouncements	Recently Issued and Adopted Accounting Pronouncements The Company is an “emerging growth company,” as defined in Section 2(a) of the Securities Act, as modified by the Jumpstart Our Business Startups Act of 2012 (the “JOBS Act”). The JOBS Act permits emerging growth companies to take advantage of an extended transition period to comply with new or revised accounting standards applicable to public companies. The Company has elected to use the extended transition period for complying with new or revised accounting standards under Section 107 of the JOBS Act. This election allows the Company to delay the adoption of new or revised accounting standards that have different effective dates for public and private companies until those standards apply to private companies. In May 2014, the FASB issued Accounting Standards Update (“ASU”) 2014-09, Revenue from Contracts with Customers (Topic 606) Note 3 In January 2017, the FASB issued ASU 2017-01, Business Combination (Topic 805)—Clarifying the Definition of a Business In August 2018, the FASB issued ASU 2018-13, Fair Value Measurement (Topic 820) - Disclosure Framework Accounting Pronouncements Issued but Not Yet Adopted In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842) Financial Instruments — Credit Losses (Topic 326), Derivatives and Hedging (Topic 815), and Leases (Topic 842): Effective Dates In June 2016, the FASB issued ASU 2016-13, “ Measurement of Credit Losses on Financial Instruments,” Financial Instruments—Credit Losses In November 2019, the FASB issued ASU 2019-10, Financial Instruments — Credit Losses (Topic 326), Derivatives and Hedging (Topic 815), and Leases (Topic 842): Effective Dates which delays the effective date of ASU 2016-13 until fiscal years beginning after December 15, 2021. The Company is currently evaluating the impact of the provisions of ASU 2016-13 on the presentation of its consolidated financial statements and related disclosures. In January 2017, the FASB issued ASU No. 2017-04, Intangibles — Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment In August 2018, the FASB issued ASU 2018-15, Intangibles—Goodwill and Other—Internal-Use Software (Subtopic 350-40) No. 2018-15 Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract (ASU 2018-15). ASU 2018-15 provides additional guidance on the accounting for costs of implementation activities performed in a cloud computing arrangement that is a service contract. The amendments in ASU 2018-15 align the requirements for capitalizing implementation costs incurred in a hosting arrangement that is a service contract with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use software (and hosting arrangements that include an internal use software license). Costs for implementation activities in the application development stage are capitalized depending on the nature of the costs, while costs incurred during the preliminary project and post implementation stages are expensed as the activities are performed. ASU 2018-15 is effective for fiscal years beginning after December 15, 2020. Early adoption of the amendments in ASU 2018-15 is permitted, including adoption in any interim period, for all entities. The amendments in ASU 2018-15 should be applied either retrospectively or prospectively to all implementation costs incurred after the date of adoption. The Company is currently assessing the effect this guidance may have on its consolidated financial statements. In December 2019, the FASB issued ASU 2019-12, “ Simplifying the Accounting for Income Taxes
