Company Information
Summary of Organization and Significant Accounting Policies	1. Summit Materials, Inc. (“Summit Inc.” and, together with its subsidiaries, the “Company”) is a vertically-integrated construction materials company. The Company is engaged in the production and sale of aggregates, cement, ready-mix concrete, asphalt paving mix and concrete products and owns and operates quarries, sand and gravel pits, two cement plants, cement distribution terminals, ready-mix concrete plants, asphalt plants and landfill sites. It is also engaged in paving and related services. The Company’s three operating and reporting segments are the West, East and Cement segments. Substantially all of the Company’s products and services are produced, consumed and performed outdoors, primarily in the spring, summer and fall. Seasonal changes and other weather-related conditions can affect the production and sales volumes of its products and delivery of services. Therefore, the financial results for any interim period are typically not indicative of the results expected for the full year. Furthermore, the Company’s sales and earnings are sensitive to national, regional and local economic conditions and to cyclical changes in construction spending, among other factors. On September 23, 2014, Summit Inc. was formed as a Delaware corporation to be a holding company. Its sole material asset is a controlling equity interest in Summit Materials Holdings L.P. (“Summit Holdings”). Pursuant to a reorganization into a holding company structure (the “Reorganization”) consummated in connection with Summit Inc.’s March 2015 initial public offering, Summit Inc. became a holding corporation operating and controlling all of the business and affairs of Summit Holdings and its subsidiaries and, through Summit Holdings, conducts its business. Together with Summit Inc., certain investment funds affiliated with Blackstone Capital Partners V L.P. and Silverhawk Summit, L.P. (collectively, the “Sponsors”) are the primary owners of Summit Holdings. Equity Offerings —Summit Inc. commenced operations on March 11, 2015 upon the pricing of the initial public offering of its Class A common stock (“IPO”). Summit Inc. raised $433.0 million, net of underwriting discounts, through the issuance of 25,555,555 shares of Class A common stock at a public offering price of $18.00 per share. Summit Inc. used the offering proceeds to purchase a number of newly-issued Class A Units (“LP Units”) from Summit Holdings equal to the number of shares of Class A common stock issued to the public. Summit Inc. caused Summit Holdings to use these proceeds: (i) to redeem $288.2 million in aggregate principal amount of outstanding 10 1 / 2 % senior notes due January 31, 2020 (“2020 Notes”); (ii) to purchase 71,428,571 Class B Units of Continental Cement Company, L.L.C. (“Continental Cement”); (iii) to pay a one-time termination fee of $13.8 million primarily to affiliates of the Sponsors in connection with the termination of a transaction and management fee agreement; and (iv) for general corporate purposes. The $288.2 million redemption of 2020 Notes was completed in the second quarter of 2015 at a redemption price equal to par plus an applicable premium of $38.2 million plus $5.2 million of accrued and unpaid interest. In connection with the IPO, Summit Inc. issued 69,007,297 shares of its Class B common stock to Summit Owner Holdco LLC (“Summit Owner Holdco”), a Delaware limited liability company owned by certain pre-IPO owners and the former holders of Class B Units of Continental Cement. The Class B common stock entitled Summit Owner Holdco, without regard to the number of shares of Class B common stock held by it, to a number of votes that is equal to the aggregate number of LP Units held by all limited partners of Summit Holdings (excluding Summit Inc.). On July 19, 2016, Summit Owner Holdco transferred 28,661,526 shares of its Class B common stock to certain holders of LP Units and the remaining 40,345,771 shares of Class B common stock were cancelled. The Class B common stock entitles holders thereof, who are also holders of LP Units, with a number of votes that is equal to the number of LP Units they hold. The Class B common stock does not participate in dividends and does not have any liquidation rights. On August 11, 2015, Summit Inc. raised $555.8 million, net of underwriting discounts, through the issuance of 22,425,000 shares of Class A common stock at a public offering price of $25.75 per share ("the August 2015 follow-on offering"). Summit Inc. used these proceeds to purchase 3,750,000 newly-issued LP Units from Summit Holdings and 18,675,000 LP Units from certain of our pre-IPO owners, at a purchase price per LP Unit equal to the public offering price per share of Class A common stock, less underwriting discounts and commissions. Summit Holdings used the proceeds from the 3,750,000 newly-issued LP Units to pay the deferred purchase price of $80.0 million related to the July 17, 2015 acquisition of a cement plant and quarry in Davenport, Iowa, and seven cement terminals along the Mississippi River (the “Davenport Assets”) and for general corporate purposes. Basis of Presentation —These unaudited consolidated financial statements were prepared in accordance with U.S. generally accepted accounting principles (“U.S. GAAP”) for interim financial information, without audit, pursuant to the rules and regulations of the Securities and Exchange Commission. Certain information and footnote disclosures typically included in financial statements prepared in accordance with U.S. GAAP have been condensed or omitted pursuant to such rules and regulations. These unaudited consolidated financial statements should be read in conjunction with the Company's audited consolidated financial statements and the notes thereto as of and for the year ended January 2, 2016. The Company continues to follow the accounting policies set forth in those consolidated financial statements. Management believes that these consolidated interim financial statements include all adjustments, normal and recurring in nature, that are necessary to present fairly the financial position of the Company as of October 1, 2016, the results of operations for the three and nine months ended October 1, 2016 and September 26, 2015 and cash flows for the nine months ended October 1, 2016 and September 26, 2015. The Company’s fiscal year is based on a 52-53 week year with each quarter composed of 13 weeks ending on a Saturday. The 53-week year occurs approximately once every seven years and occurred in 2015. The additional week in the 53-week year was included in the fourth quarter of 2015. Principles of Consolidation —The consolidated financial statements include the accounts of Summit Inc. and its majority owned subsidiaries. All intercompany balances and transactions have been eliminated. As a result of the Reorganization, Summit Holdings became a variable interest entity over which Summit Inc. has 100% voting power and control and for which Summit Inc. has the obligation to absorb losses and the right to receive benefits. As a result, Summit Inc. is Summit Holdings’ primary beneficiary and thus consolidates Summit Holdings in its consolidated financial statements with a corresponding noncontrolling interest elimination, which was 24.5% and 50.3% as of October 1, 2016 and January 2, 2016, respectively. Noncontrolling interests in consolidated subsidiaries represent a 20% ownership in Ohio Valley Asphalt, LLC and, prior to the IPO and concurrent purchase of the noncontrolling interests of Continental Cement, a 30% redeemable ownership in Continental Cement. The Company attributes consolidated stockholders’ equity and net income separately to the controlling and noncontrolling interests. The Company accounts for investments in entities for which it has an ownership of 20% to 50% using the equity method of accounting. Use of Estimates —Preparation of these consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions. These estimates and the underlying assumptions affect the amounts of assets and liabilities reported, disclosures about contingent assets and liabilities and reported amounts of revenue and expenses. Such estimates include the valuation of accounts receivable, inventories, goodwill, intangibles and other long-lived assets, pension and other postretirement obligations and asset retirement obligations. Estimates also include revenue earned on contracts and costs to complete contracts. Most of the Company’s paving and related services are performed under fixed unit-price contracts with state and local governmental entities. Management regularly evaluates its estimates and assumptions based on historical experience and other factors, including the current economic environment. As future events and their effects cannot be determined with precision, actual results can differ significantly from estimates made. Changes in estimates, including those resulting from continuing changes in the economic environment, are reflected in the Company’s consolidated financial statements when the change in estimate occurs. Business and Credit Concentrations— The Company’s operations are conducted primarily across 24 U.S. states and in British Columbia, Canada, with the most significant revenue generated in Texas, Kansas, Utah, Missouri and Kentucky. The Company’s accounts receivable consist primarily of amounts due from customers within these areas. Therefore, collection of these accounts is dependent on the economic conditions in the aforementioned states, as well as specific situations affecting individual customers. Credit granted within the Company’s trade areas has been granted to many customers, and management does not believe that a significant concentration of credit exists with respect to any individual customer or group of customers. No single customer accounted for more than 10% of the Company’s total revenue in the three and nine months ended October 1, 2016 and September 26, 2015. Earnings per Share— The Company computes basic earnings per share attributable to stockholders by dividing income attributable to Summit Inc. by the weighted-average shares of Class A common stock outstanding. Diluted earnings per share reflects the potential dilution beyond shares for basic earnings per share that could occur if securities or other contracts to issue common stock were exercised, converted into common stock, or resulted in the issuance of common stock that would have shared in the Company’s earnings. Since the Class B common stock has no economic value, those shares are not included in the weighted-average common share amount for basic or diluted earnings per share. In addition, as the shares of Class A common stock are issued by Summit Inc., the earnings and equity interests of noncontrolling interests are not included in basic earnings per share. Fair Value Measurements— Certain acquisitions made by the Company require the payment of contingent amounts of purchase consideration. These payments are contingent on specified operating results being achieved in periods subsequent to the acquisition and will only be made if earn-out thresholds are achieved. Contingent consideration obligations are measured at fair value each reporting period. Any adjustments to fair value are recognized in earnings in the period identified. The Company has entered into interest rate derivatives on $200.0 million of its term loan borrowings to add stability to interest expense and to manage its exposure to interest rate movements. The effective portion of changes in the fair value of derivatives designated and that qualify as cash flow hedges is recorded in accumulated other comprehensive income and will be subsequently reclassified into earnings in the period that the hedged forecasted transaction affects earnings. The fair value of contingent consideration and derivatives as of October 1, 2016 and January 2, 2016 was: October 1, January 2, 2016 2016 Current portion of acquisition-related liabilities and Accrued expenses: Contingent consideration $ $ Cash flow hedges Acquisition-related liabilities and Other noncurrent liabilities Contingent consideration $ $ Cash flow hedges The fair value of contingent consideration was based on unobservable, or Level 3, inputs, including projected probability-weighted cash payments and an 11.0% discount rate, which reflects a market discount rate. Changes in fair value may occur as a result of a change in actual or projected cash payments, the probability weightings applied by the Company to projected payments or a change in the discount rate. Significant increases or decreases in any of these inputs in isolation could result in a lower, or higher, fair value measurement. The fair value of the cash flow hedges are based on observable, or Level 2, inputs such as interest rates, bond yields and prices in inactive markets. There were no material valuation adjustments to the derivatives in the three or nine months ended October 1, 2016 and September 26, 2015, and approximately $4.1 million of adjustments to contingent consideration in the nine months ended October 1, 2016. Financial Instruments —The Company’s financial instruments include debt and certain acquisition-related liabilities (deferred consideration and noncompete obligations). The carrying value and fair value of these financial instruments as of October 1, 2016 and January 2, 2016 was: October 1, 2016 January 2, 2016 Fair Value Carrying Value Fair Value Carrying Value Level 2 Long-term debt(1) $ $ $ $ Level 3 Current portion of deferred consideration and noncompete obligations(2) Long term portion of deferred consideration and noncompete obligations(3) (1) Balances include $6.5 million of current portion of debt and exclude capitalized loan costs of $15.6 million and $11.7 million as of October 1, 2016 and January 2, 2016, respectively. (2) Included in current portion of acquisition-related liabilities on the consolidated balance sheets. (3) Included in acquisition-related liabilities on the consolidated balance sheets. The fair value of debt was determined based on observable, or Level 2, inputs, such as interest rates, bond yields and quoted prices in inactive markets. The fair values of the deferred consideration and noncompete obligations were determined based on unobservable, or Level 3, inputs, including the cash payment terms in the purchase agreements and a discount rate reflecting the Company’s credit risk. Redeemable Noncontrolling Interest — On March 17, 2015, upon the consummation of the IPO and the transactions contemplated by a contribution and purchase agreement entered into with the holders of all of the outstanding Class B Units of Continental Cement, Continental Cement became a wholly-owned indirect subsidiary of Summit Inc. The noncontrolling interests of Continental Cement were acquired for aggregate consideration of $64.1 million, consisting of $35.0 million of cash, 1,029,183 shares of Summit Inc.’s Class A common stock and $15.0 million aggregate principal amount of non-interest bearing notes payable in six annual installments of $2.5 million, beginning on March 17, 2016. New Accounting Standards — In March 2016, the Financial Accounting Standards Board (“FASB”) issued a new accounting standard with targeted amendments to the accounting for employee share-based payments. Accounting Standards Update (“ASU”) 2016-09, Improvements to Employee Share-Based Payment Accounting , requires that the income tax effect of share-based awards be recognized in the income statement and allows entities to elect an accounting method to recognize forfeitures as they occur or to estimate forfeitures, as is currently required. The ASU is effective for public entities for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2016. However, the Company early adopted this ASU as of the beginning of fiscal year 2016 and made an election to recognize forfeitures as they occur. The ASU adoption was applied using a modified retrospective method by means of a $1.7 million cumulative-effect adjustment to accumulated earnings as of the beginning of the fiscal year. In February 2016, the FASB issued a new accounting standard related to lease accounting, ASU No. 2016-02, Leases , which will result in lessees recognizing most leases on the balance sheet. Lessees are required to disclose more quantitative and qualitative information about their leases than current U.S. GAAP requires. The ASU is effective for public entities for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2018. As of October 1, 2016 and January 2, 2016, the Company’s undiscounted minimum contractual commitments under long-term operating leases, which were not recorded on the balance sheet, were $28.6 million and $21.9 million, respectively, which is an estimate of the effect to lease obligations and property, plant and equipment that the new accounting standard would have as of the dates noted. In May 2014, the FASB issued a new accounting standard to improve and converge the financial reporting requirements for revenue from contracts with customers. ASU No. 2014-09, Revenue from Contracts with Customers , prescribes a five-step model for revenue recognition that will replace most existing revenue recognition guidance in U.S. GAAP. The ASU will supersede nearly all existing revenue recognition guidance under U.S. GAAP and provides that an entity 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. This update also requires additional disclosure about the nature, amount, timing and uncertainty of revenue and cash flows arising from customer contracts, including significant judgments and changes in judgments, and assets recognized from costs incurred to obtain or fulfill a contract. ASU No. 2014-09 allows for either full retrospective or modified retrospective adoption. In July 2015, the FASB postponed the effective date of the new revenue standard by one year to the first quarter of 2018. Early adoption is permitted, but no earlier than 2017. Management is currently assessing the effect that the adoption of this standard will have on the consolidated financial statements. Reclassifications — Certain amounts in the prior year have been reclassified to conform to the current period’s presentation.

The fair value of contingent consideration and derivatives as of October 1, 2016 and January 2, 2016 was: October 1, January 2, 2016 2016 Current portion of acquisition-related liabilities and Accrued expenses: Contingent consideration $ $ Cash flow hedges Acquisition-related liabilities and Other noncurrent liabilities Contingent consideration $ $ Cash flow hedges The fair value of contingent consideration was based on unobservable, or Level 3, inputs, including projected probability-weighted cash payments and an 11.0% discount rate, which reflects a market discount rate. Changes in fair value may occur as a result of a change in actual or projected cash payments, the probability weightings applied by the Company to projected payments or a change in the discount rate. Significant increases or decreases in any of these inputs in isolation could result in a lower, or higher, fair value measurement. The fair value of the cash flow hedges are based on observable, or Level 2, inputs such as interest rates, bond yields and prices in inactive markets. There were no material valuation adjustments to the derivatives in the three and nine months ended October 1, 2016 and September 26, 2015 and approximately $4.1 million of adjustments to contingent consideration in the nine months ended October 1, 2016. Financial Instruments —The Company’s financial instruments include debt and certain acquisition-related liabilities (deferred consideration and noncompete obligations). The carrying value and fair value of these financial instruments as of October 1, 2016 and January 2, 2016 was: October 1, 2016 January 2, 2016 Fair Value Carrying Value Fair Value Carrying Value Level 2 Long-term debt(1) $ $ $ $ Level 3 Current portion of deferred consideration and noncompete obligations(2) Long term portion of deferred consideration and noncompete obligations(3) (1) Balances include $6.5 million of current portion of debt and exclude capitalized loan costs of $15.6 million and $11.7 million as of October 1, 2016 and January 2, 2016, respectively. (2) Included in current portion of acquisition-related liabilities on the consolidated balance sheets. (3) Included in acquisition-related liabilities on the consolidated balance sheets. The fair value of debt was determined based on observable, or Level 2 inputs, such as interest rates, bond yields and quoted prices in inactive markets. The fair values of the deferred consideration and noncompete obligations were determined based on unobservable, or Level 3, inputs, including the cash payment terms in the purchase agreements and a discount rate reflecting the Company’s credit risk. Redeemable Noncontrolling Interest — On March 17, 2015, upon the consummation of the IPO and the transactions contemplated by a contribution and purchase agreement entered into with the holders of all of the outstanding Class B Units of Continental Cement, Continental Cement became a wholly-owned indirect subsidiary of Summit LLC. The noncontrolling interests of Continental Cement were acquired for aggregate consideration of $64.1 million, consisting of $35.0 million of cash, 1,029,183 shares of Summit Inc.’s Class A common stock and $15.0 million aggregate principal amount of non-interest bearing notes payable in six annual installments of $2.5 million, beginning on March 17, 2016. The notes payable is a liability of Summit Holdings and, is therefore not included in the liabilities of Summit LLC. However, Summit LLC made a $2.5 million distribution to Summit Holdings in the nine months ended October 1, 2016 so that Summit Holdings could make the deferred consideration payment due on March 17, 2016. New Accounting Standards — In March 2016, the Financial Accounting Standards Board (“FASB”) issued a new accounting standard with targeted amendments to the accounting for employee share-based payments. Accounting Standards Update (“ASU”) 2016-09, Improvements to Employee Share-Based Payment Accounting , requires that the income tax effect of share-based awards be recognized in the income statement and allows entities to elect an accounting method to recognize forfeitures as they occur or to estimate forfeitures, as is currently required. The ASU is effective for public entities for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2016. However, the Company early adopted this ASU as of the beginning of fiscal year 2016 and made an election to recognize forfeitures as they occur. The ASU adoption was applied using a modified retrospective method by means of a $1.7 million cumulative-effect adjustment to accumulated deficit as of the beginning of the fiscal year. In February 2016, the FASB issued a new accounting standard related to lease accounting, ASU No. 2016-02, Leases , which will result in lessees recognizing most leases on the balance sheet. Lessees are required to disclose more quantitative and qualitative information about their leases than current U.S. GAAP requires. The ASU is effective for public entities for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2018. As of October 1, 2016 and January 2, 2016, the Company’s undiscounted minimum contractual commitments under long-term operating leases, which were not recorded on the balance sheet, were $28.6 million and $21.9 million, respectively, which is an estimate of the effect to lease obligations and property, plant and equipment that the new accounting standard would have as of the dates noted. In May 2014, the FASB issued a new accounting standard to improve and converge the financial reporting requirements for revenue from contracts with customers. ASU No 2014-09, Revenue from Contracts with Customers , prescribes a five-step model for revenue recognition that will replace most existing revenue recognition guidance in U.S. GAAP. The ASU will supersede nearly all existing revenue recognition guidance under U.S. GAAP and provides that an entity 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. This update also requires additional disclosure about the nature, amount, timing and uncertainty of revenue and cash flows arising from customer contracts, including significant judgments and changes in judgments, and assets recognized from costs incurred to obtain or fulfill a contract. ASU No. 2014-09 allows for either full retrospective or modified retrospective adoption. In July 2015, the FASB postponed the effective date of the new revenue standard by one year to the first quarter of 2018. Early adoption is permitted, but no earlier than 2017. Management is currently assessing the effect that the adoption of this standard will have on the consolidated financial statements. Reclassifications — Certain amounts in the prior year have been reclassified to conform to the current period’s presentation.

Share-based Compensation

Share-based Compensation	9 Months Ended

Share-based Compensation	2. Prior to the IPO and Reorganization, the capital structure of Summit Holdings consisted of six different classes of limited partnership interests (Class A-1, Class A-2, Class B-1, Class C, Class D-1 and Class D-2), each of which was subject to unique distribution rights. There were no outstanding Class A-2 interests. In connection with the IPO and the Reorganization, the limited partnership agreement of Summit Holdings was amended and restated to, among other things, modify its capital structure by creating the LP Units (“Reclassification”). Immediately following the Reclassification, 69,007,297 LP Units were outstanding. In addition, in substitution for part of the economic benefit of the Class C and Class D interests that was not reflected in the conversion of such interests to LP Units, warrants were issued to holders of Class C interests to purchase an aggregate of 160,333 shares of Class A common stock, and options were issued to holders of Class D interests to purchase an aggregate of 4,358,842 shares of Class A common stock (“leverage restoration options”). The exercise price of the warrants and leverage restoration options is the IPO price of $18.00 per share. In conjunction with the Reclassification of the equity-based awards, the Company recognized a $14.5 million modification charge in general and administrative expenses in the nine months ended September 26, 2015. The leverage restoration options were granted under the Summit Materials, Inc. 2015 Omnibus Incentive Plan (the “Omnibus Incentive Plan”). The leverage restoration options that correlated to time-vesting interests vest over four years beginning on the Reclassification date and the leverage restoration options that correlated to performance-vesting interests vest when both the applicable return multiple is achieved and a four year time-vesting condition is satisfied. The four-year time-vesting condition will be satisfied with respect to 25% on each of the first four anniversaries of the Reclassification date, subject to the employee’s continued employment through the applicable vesting date. The Company also granted 240,000 options to purchase shares of Class A common stock under the Omnibus Incentive Plan to certain employees some of whom had not previously been granted equity-based interests. These stock options have an exercise price of $18.00 per share, the IPO price, and are subject to a time-based vesting condition that will be satisfied with respect to 25% of the award on each of the first four anniversaries of the grant date, subject to the employee’s continued employment through the applicable vesting date. In the nine months ended October 1, 2016, Summit Inc. acquired 25,812,254 LP Units in exchange for an equal number of shares of Class A common stock, of which 21,482,082 LP Units were exchanged by certain investment funds associated with or designated by The Blackstone Group L.P. (“Blackstone”). Blackstone subsequently sold the shares of Class A common stock it received through underwritten public offerings. As a result of these transactions and Blackstone’s prior exchange and sale of LP Units, the performance target associated with certain LP Units and leverage restoration options which was based on Blackstone receiving a 1.75 times return on its initial investment, was achieved. In addition, on August 9, 2016, the Board of Directors of Summit Inc. determined that it was in the best interest of the Company to waive the 3.0 times threshold on the remaining unvested performance-based LP Units and leverage restoration options. The Company recognized $12.5 million and $37.3 million in general and administrative expenses in the three and nine months ended October 1, 2016, respectively, related to the vesting of these performance-based awards.

Income Taxes

Income Taxes	9 Months Ended
	Oct. 01, 2016
Income Taxes	9. Summit Inc.’s tax provision includes its proportional share of Summit Holdings’ tax attributes. Summit Holdings’ subsidiaries are primarily limited liability companies, but do include certain entities organized as C corporations and a Canadian subsidiary. The tax attributes related to the limited liability companies are passed on to Summit Holdings and then to its partners, including Summit Inc. The tax attributes associated with the C corporation and Canadian subsidiaries are fully reflected in the Company’s accounts. As of January 2, 2016, Summit Inc. had a valuation allowance on net deferred tax assets of $263.8 million, which primarily consisted of a temporary difference related to the tax intangible assets basis in excess of book. In assessing the realizability of deferred tax assets, including the deferred tax assets resulting from the expected taxable loss in 2016 and those generated under the tax receivable agreement described below, management determined that it was more likely than not that the deferred tax assets will not be realized. The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income during the periods in which those temporary differences become deductible and consideration of tax-planning strategies. Considering these factors, a full valuation allowance was recorded, which has resulted in no provision for the three and nine months ended October 1, 2016. Tax Receivable Agreement —Upon the consummation of the Reorganization, the Company entered into a tax receivable agreement with the holders of LP Units and certain other pre-IPO owners (“Investor Entities”) that provides for the payment by Summit Inc. to exchanging holders of LP Units of 85% of the benefits, if any, that Summit Inc. is deemed to realize as a result of (i) increases in the tax basis of tangible and intangible assets of Summit Holdings and (ii) the utilization of certain net operating losses of the Investor Entities and certain other tax benefits related to entering into the tax receivable agreement, including tax benefits attributable to payments under the tax receivable agreement. In the nine months ended October 1, 2016, 25,812,254 LP units were acquired by Summit Inc. in exchange for an equal number of newly-issued shares of Summit Inc.’s Class A common stock. This exchange resulted in a deferred tax asset of approximately $222.3 million, 85% of which is a liability due to the holders of the exchanged LP Units. As discussed above, a full valuation allowance was recognized on the deferred tax asset. As realization of the tax benefit is not currently deemed probable, the related liability to the former holders of LP Units exchanged is not considered probable and is not included in the consolidated balance sheet. The Company considers all available evidence (both positive and negative), including continuing periods of income and other tax planning strategies, in determining whether realization of the tax benefit is more likely than not. The Company will continue to monitor facts and circumstances in the reassessment of the likelihood that the tax benefit will be realized. If this were to occur, the valuation allowance, or portion thereof, would be released with a corresponding charge to Other Expense for the liability due to former LP Unit holders equal to 85% of the valuation allowance release. Tax Distributions – The holders of Summit Holdings’ LP Units, including Summit Inc., incur U.S. federal, state and local income taxes on their share of any taxable income of Summit Holdings. The limited partnership agreement of Summit Holdings provides for pro rata cash distributions (“tax distributions”) to the holders of the LP Units in an amount generally calculated to provide each holder of LP Units with sufficient cash to cover its tax liability in respect of the LP Units. In general, these tax distributions are computed based on Summit Holdings’ estimated taxable income allocated to each holder of LP Units multiplied by an assumed tax rate equal to the highest effective marginal combined U.S. federal, state and local income tax rate applicable to an individual or corporate resident in New York, New York (or a corporate resident in certain circumstances). In the nine months ended October 1, 2016, Summit Holdings paid tax distributions totaling $25.5 million, of which $9.0 million was paid to holders of its LP Units, other than Summit Inc., and $16.5 million was paid to Summit Inc. C Corporation Subsidiaries — The effective income tax rate for the C corporations differ from the statutory federal rate primarily due to (1) tax depletion expense in excess of the expense recorded under U.S. GAAP, (2) state income taxes and the effect of graduated tax rates and (3) various other items such as limitations on meals and entertainment and other costs. The effective income tax rate for the Canadian subsidiary is not significantly different from its historical effective tax rate. As of October 1, 2016, and January 2, 2016, Summit Inc. and its subsidiaries had not recognized any liabilities for uncertain tax positions. The Company records interest and penalties as a component of the income tax provision. No material interest or penalties were recognized in income tax expense during the three and nine months ended October 1, 2016, or September 26, 2015.

Income Taxes	9. Summit LLC is a limited liability company and passes its tax attributes for federal and state tax purposes to its parent company and is generally not subject to federal or state income tax. However, certain subsidiary entities file federal, state, and Canadian income tax returns due to their status as taxable entities in the respective jurisdiction. The effective income tax rate for the C Corporations differs from the statutory federal rate primarily due to (1) tax depletion expense in excess of the expense recorded under U.S. GAAP, (2) state income taxes and the effect of graduated tax rates and (3) various other items, such as limitations on meals and entertainment and other costs. The effective income tax rate for the Canadian subsidiary is not significantly different from its historical effective tax rate.

Commitments and Contingencies	11. COMMITMENTS AND CONTINGENCIES The Company is party to certain legal actions arising from the ordinary course of business activities. Accruals are recorded when the outcome is probable and can be reasonably estimated. While the ultimate results of claims and litigation cannot be predicted with certainty, management expects that the ultimate resolution of all pending or threatened claims and litigation will not have a material effect on the Company’s consolidated results of operations, financial position or liquidity. The Company records legal fees as incurred. Litigation and Claims —The Company is obligated under an indemnification agreement entered into with the sellers of Harper Contracting, Inc., Harper Sand and Gravel, Inc., Harper Excavating, Inc., Harper Ready Mix Company, Inc. and Harper Investments, Inc. for the sellers’ ownership interests in a joint venture agreement. The Company has the rights to any benefits under the joint venture as well as the assumption of any obligations, but does not own equity interests in the joint venture. The joint venture has incurred significant losses on a highway project in Utah, which have resulted in requests for funding from the joint venture partners and ultimately from the Company. Through October 1, 2016, the Company has funded $8.8 million, $4.0 million in 2012 and $4.8 million in 2011. In 2012 and 2011, the Company recognized losses on the indemnification agreement of $8.0 million and $1.9 million, respectively. As of October 1, 2016 and January 2, 2016, an accrual of $4.3 million was recorded in other noncurrent liabilities as management’s best estimate of future funding obligations. Environmental Remediation and Site Restoration —The Company’s operations are subject to and affected by federal, state, provincial and local laws and regulations relating to the environment, health and safety and other regulatory matters. These operations require environmental operating permits, which are subject to modification, renewal and revocation. The Company regularly monitors and reviews its operations, procedures and policies for compliance with these laws and regulations. Despite these compliance efforts, risk of environmental liability is inherent in the operation of the Company’s business, as it is with other companies engaged in similar businesses and there can be no assurance that environmental liabilities or noncompliance will not have a material adverse effect on the Company’s consolidated financial condition, results of operations or liquidity. The Company has site restoration obligations arising from regulatory and contractual requirements to perform reclamation activities at the time certain quarries and landfills are closed. As of October 1, 2016 and January 2, 2016, $18.4 million and $18.7 million, respectively, were included in other noncurrent liabilities on the consolidated balance sheets and $5.2 million and $2.0 million, respectively, were included in accrued expenses for future reclamation costs.

Other —The Company is obligated under various firm purchase commitments for certain raw materials and services that are in the ordinary course of business. Management does not expect any significant changes in the market value of these goods and services during the commitment period that would have a material adverse effect on the financial condition, results of operations, and cash flows of the Company. The terms of the purchase commitments generally approximate one year.

Segment Information

Segment Information	9 Months Ended
	Oct. 01, 2016
Segment Information	13. SEGMENT INFORMATION The Company has three operating segments: West; East; and Cement, which are its reporting segments. These segments are consistent with the Company’s management reporting structure. In the fourth quarter of 2015, the Company reorganized the operations and management reporting structure of the East and Cement segment operations, resulting in a change to its reportable business segments. The Company now conducts the cement business separate from the regional segments. As a result, the cement business is a reportable business segment. In addition, the Company has combined the materials-based businesses centered in Kansas and Missouri with the Kentucky-based operations, creating an expanded East segment and eliminating what was the Central region. These changes did not affect the West segment. Amounts in prior periods have been revised to reflect the current reporting structure. The operating results of each segment are regularly reviewed and evaluated by the Chief Executive Officer, the Company’s Chief Operating Decision Maker (“CODM”). The CODM primarily evaluates the performance of its segments and allocates resources to them based on a segment profit metric that we call Adjusted EBITDA, which is computed as earnings from continuing operations before interest, taxes, depreciation, depletion, amortization, accretion, share-based compensation, and transaction costs, as well as various other non-recurring, non-cash amounts. The West and East segments have several acquired subsidiaries that are engaged in various activities including quarry mining, aggregate production and contracting. The Cement segment is engaged in the production of Portland cement. Assets employed by each segment include assets directly identified with those operations. Corporate assets consist primarily of cash, property, plant and equipment for corporate operations and other assets not directly identifiable with a reportable business segment. The accounting policies applicable to each segment are consistent with those used in the consolidated financial statements. The following tables display selected financial data for the Company’s reportable business segments as of October 1, 2016 and January 2, 2016 and for the three and nine months ended October 1, 2016 and September 26, 2015: Three months ended Nine months ended October 1, September 26, October 1, September 26, 2016 2015 2016 2015 Revenue*: West $ $ $ $ East Cement Total revenue $ $ $ $ * Three months ended Nine months ended October 1, September 26, October 1, September 26, 2016 2015 2016 2015 Adjusted EBITDA: West $ $ $ $ East Cement Corporate and other Total Adjusted EBITDA Interest expense Depreciation, depletion and amortization Accretion IPO/ Legacy equity modification costs — Loss on debt financings — — Transaction costs Management fees and expenses — — — Non-cash compensation Other Income (loss) from continuing operations before taxes $ $ $ $ Nine months ended October 1, September 26, 2016 2015 Purchases of property, plant and equipment West $ $ East Cement Total reportable segments Corporate and other Total purchases of property, plant and equipment $ $ Three months ended Nine months ended October 1, September 26, October 1, September 26, 2016 2015 2016 2015 Depreciation, depletion, amortization and accretion: West $ $ $ $ East Cement Total reportable segments Corporate and other Total depreciation, depletion, amortization and accretion $ $ $ $ October 1, January 2, 2016 2016 Total assets: West $ $ East Cement Total reportable segments Corporate and other Total $ $ Three months ended Nine months ended October 1, September 26, October 1, September 26, 2016 2015 2016 2015 Revenue by product*: Aggregates $ $ $ $ Cement Ready-mix concrete Asphalt Paving and related services Other Total revenue $ $ $ $ *

Summary of Organization and S23

Summary of Organization and Significant Accounting Policies (Policies)	9 Months Ended
	Oct. 01, 2016
Company Information
Initial Public Offering	Equity Offerings —Summit Inc. commenced operations on March 11, 2015 upon the pricing of the initial public offering of its Class A common stock (“IPO”). Summit Inc. raised $433.0 million, net of underwriting discounts, through the issuance of 25,555,555 shares of Class A common stock at a public offering price of $18.00 per share. Summit Inc. used the offering proceeds to purchase a number of newly-issued Class A Units (“LP Units”) from Summit Holdings equal to the number of shares of Class A common stock issued to the public. Summit Inc. caused Summit Holdings to use these proceeds: (i) to redeem $288.2 million in aggregate principal amount of outstanding 10 1 / 2 % senior notes due January 31, 2020 (“2020 Notes”); (ii) to purchase 71,428,571 Class B Units of Continental Cement Company, L.L.C. (“Continental Cement”); (iii) to pay a one-time termination fee of $13.8 million primarily to affiliates of the Sponsors in connection with the termination of a transaction and management fee agreement; and (iv) for general corporate purposes. The $288.2 million redemption of 2020 Notes was completed in the second quarter of 2015 at a redemption price equal to par plus an applicable premium of $38.2 million plus $5.2 million of accrued and unpaid interest. In connection with the IPO, Summit Inc. issued 69,007,297 shares of its Class B common stock to Summit Owner Holdco LLC (“Summit Owner Holdco”), a Delaware limited liability company owned by certain pre-IPO owners and the former holders of Class B Units of Continental Cement. The Class B common stock entitled Summit Owner Holdco, without regard to the number of shares of Class B common stock held by it, to a number of votes that is equal to the aggregate number of LP Units held by all limited partners of Summit Holdings (excluding Summit Inc.). On July 19, 2016, Summit Owner Holdco transferred 28,661,526 shares of its Class B common stock to certain holders of LP Units and the remaining 40,345,771 shares of Class B common stock were cancelled. The Class B common stock entitles holders thereof, who are also holders of LP Units, with a number of votes that is equal to the number of LP Units they hold. The Class B common stock does not participate in dividends and does not have any liquidation rights.
Follow-On Offering	On August 11, 2015, Summit Inc. raised $555.8 million, net of underwriting discounts, through the issuance of 22,425,000 shares of Class A common stock at a public offering price of $25.75 per share ("the August 2015 follow-on offering"). Summit Inc. used these proceeds to purchase 3,750,000 newly-issued LP Units from Summit Holdings and 18,675,000 LP Units from certain of our pre-IPO owners, at a purchase price per LP Unit equal to the public offering price per share of Class A common stock, less underwriting discounts and commissions. Summit Holdings used the proceeds from the 3,750,000 newly-issued LP Units to pay the deferred purchase price of $80.0 million related to the July 17, 2015 acquisition of a cement plant and quarry in Davenport, Iowa, and seven cement terminals along the Mississippi River (the “Davenport Assets”) and for general corporate purposes.
Basis of Presentation	Basis of Presentation —These unaudited consolidated financial statements were prepared in accordance with U.S. generally accepted accounting principles (“U.S. GAAP”) for interim financial information, without audit, pursuant to the rules and regulations of the Securities and Exchange Commission. Certain information and footnote disclosures typically included in financial statements prepared in accordance with U.S. GAAP have been condensed or omitted pursuant to such rules and regulations. These unaudited consolidated financial statements should be read in conjunction with the Company's audited consolidated financial statements and the notes thereto as of and for the year ended January 2, 2016. The Company continues to follow the accounting policies set forth in those consolidated financial statements. Management believes that these consolidated interim financial statements include all adjustments, normal and recurring in nature, that are necessary to present fairly the financial position of the Company as of October 1, 2016, the results of operations for the three and nine months ended October 1, 2016 and September 26, 2015 and cash flows for the nine months ended October 1, 2016 and September 26, 2015. The Company’s fiscal year is based on a 52-53 week year with each quarter composed of 13 weeks ending on a Saturday. The 53-week year occurs approximately once every seven years and occurred in 2015. The additional week in the 53-week year was included in the fourth quarter of 2015.
Principles of Consolidation	Principles of Consolidation —The consolidated financial statements include the accounts of Summit Inc. and its majority owned subsidiaries. All intercompany balances and transactions have been eliminated. As a result of the Reorganization, Summit Holdings became a variable interest entity over which Summit Inc. has 100% voting power and control and for which Summit Inc. has the obligation to absorb losses and the right to receive benefits. As a result, Summit Inc. is Summit Holdings’ primary beneficiary and thus consolidates Summit Holdings in its consolidated financial statements with a corresponding noncontrolling interest elimination, which was 24.5% and 50.3% as of October 1, 2016 and January 2, 2016, respectively. Noncontrolling interests in consolidated subsidiaries represent a 20% ownership in Ohio Valley Asphalt, LLC and, prior to the IPO and concurrent purchase of the noncontrolling interests of Continental Cement, a 30% redeemable ownership in Continental Cement. The Company attributes consolidated stockholders’ equity and net income separately to the controlling and noncontrolling interests. The Company accounts for investments in entities for which it has an ownership of 20% to 50% using the equity method of accounting.
Use of Estimates	Use of Estimates —Preparation of these consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions. These estimates and the underlying assumptions affect the amounts of assets and liabilities reported, disclosures about contingent assets and liabilities and reported amounts of revenue and expenses. Such estimates include the valuation of accounts receivable, inventories, goodwill, intangibles and other long-lived assets, pension and other postretirement obligations and asset retirement obligations. Estimates also include revenue earned on contracts and costs to complete contracts. Most of the Company’s paving and related services are performed under fixed unit-price contracts with state and local governmental entities. Management regularly evaluates its estimates and assumptions based on historical experience and other factors, including the current economic environment. As future events and their effects cannot be determined with precision, actual results can differ significantly from estimates made. Changes in estimates, including those resulting from continuing changes in the economic environment, are reflected in the Company’s consolidated financial statements when the change in estimate occurs.
Business and Credit Concentrations	Business and Credit Concentrations— The Company’s operations are conducted primarily across 24 U.S. states and in British Columbia, Canada, with the most significant revenue generated in Texas, Kansas, Utah, Missouri and Kentucky. The Company’s accounts receivable consist primarily of amounts due from customers within these areas. Therefore, collection of these accounts is dependent on the economic conditions in the aforementioned states, as well as specific situations affecting individual customers. Credit granted within the Company’s trade areas has been granted to many customers, and management does not believe that a significant concentration of credit exists with respect to any individual customer or group of customers. No single customer accounted for more than 10% of the Company’s total revenue in the three and nine months ended October 1, 2016 and September 26, 2015.
Earnings per Share	Earnings per Share— The Company computes basic earnings per share attributable to stockholders by dividing income attributable to Summit Inc. by the weighted-average shares of Class A common stock outstanding. Diluted earnings per share reflects the potential dilution beyond shares for basic earnings per share that could occur if securities or other contracts to issue common stock were exercised, converted into common stock, or resulted in the issuance of common stock that would have shared in the Company’s earnings. Since the Class B common stock has no economic value, those shares are not included in the weighted-average common share amount for basic or diluted earnings per share. In addition, as the shares of Class A common stock are issued by Summit Inc., the earnings and equity interests of noncontrolling interests are not included in basic earnings per share.
Fair Value Measurements	Fair Value Measurements— Certain acquisitions made by the Company require the payment of contingent amounts of purchase consideration. These payments are contingent on specified operating results being achieved in periods subsequent to the acquisition and will only be made if earn-out thresholds are achieved. Contingent consideration obligations are measured at fair value each reporting period. Any adjustments to fair value are recognized in earnings in the period identified. The Company has entered into interest rate derivatives on $200.0 million of its term loan borrowings to add stability to interest expense and to manage its exposure to interest rate movements. The effective portion of changes in the fair value of derivatives designated and that qualify as cash flow hedges is recorded in accumulated other comprehensive income and will be subsequently reclassified into earnings in the period that the hedged forecasted transaction affects earnings. The fair value of contingent consideration and derivatives as of October 1, 2016 and January 2, 2016 was: October 1, January 2, 2016 2016 Current portion of acquisition-related liabilities and Accrued expenses: Contingent consideration $ $ Cash flow hedges Acquisition-related liabilities and Other noncurrent liabilities Contingent consideration $ $ Cash flow hedges The fair value of contingent consideration was based on unobservable, or Level 3, inputs, including projected probability-weighted cash payments and an 11.0% discount rate, which reflects a market discount rate. Changes in fair value may occur as a result of a change in actual or projected cash payments, the probability weightings applied by the Company to projected payments or a change in the discount rate. Significant increases or decreases in any of these inputs in isolation could result in a lower, or higher, fair value measurement. The fair value of the cash flow hedges are based on observable, or Level 2, inputs such as interest rates, bond yields and prices in inactive markets. There were no material valuation adjustments to the derivatives in the three or nine months ended October 1, 2016 and September 26, 2015, and approximately $4.1 million of adjustments to contingent consideration in the nine months ended October 1, 2016.
Financial Instruments	Financial Instruments —The Company’s financial instruments include debt and certain acquisition-related liabilities (deferred consideration and noncompete obligations). The carrying value and fair value of these financial instruments as of October 1, 2016 and January 2, 2016 was: October 1, 2016 January 2, 2016 Fair Value Carrying Value Fair Value Carrying Value Level 2 Long-term debt(1) $ $ $ $ Level 3 Current portion of deferred consideration and noncompete obligations(2) Long term portion of deferred consideration and noncompete obligations(3) (1) Balances include $6.5 million of current portion of debt and exclude capitalized loan costs of $15.6 million and $11.7 million as of October 1, 2016 and January 2, 2016, respectively. (2) Included in current portion of acquisition-related liabilities on the consolidated balance sheets. (3) Included in acquisition-related liabilities on the consolidated balance sheets. The fair value of debt was determined based on observable, or Level 2, inputs, such as interest rates, bond yields and quoted prices in inactive markets. The fair values of the deferred consideration and noncompete obligations were determined based on unobservable, or Level 3, inputs, including the cash payment terms in the purchase agreements and a discount rate reflecting the Company’s credit risk.
Redeemable Noncontrolling Interest	Redeemable Noncontrolling Interest — On March 17, 2015, upon the consummation of the IPO and the transactions contemplated by a contribution and purchase agreement entered into with the holders of all of the outstanding Class B Units of Continental Cement, Continental Cement became a wholly-owned indirect subsidiary of Summit Inc. The noncontrolling interests of Continental Cement were acquired for aggregate consideration of $64.1 million, consisting of $35.0 million of cash, 1,029,183 shares of Summit Inc.’s Class A common stock and $15.0 million aggregate principal amount of non-interest bearing notes payable in six annual installments of $2.5 million, beginning on March 17, 2016.
New Accounting Standards	New Accounting Standards — In March 2016, the Financial Accounting Standards Board (“FASB”) issued a new accounting standard with targeted amendments to the accounting for employee share-based payments. Accounting Standards Update (“ASU”) 2016-09, Improvements to Employee Share-Based Payment Accounting , requires that the income tax effect of share-based awards be recognized in the income statement and allows entities to elect an accounting method to recognize forfeitures as they occur or to estimate forfeitures, as is currently required. The ASU is effective for public entities for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2016. However, the Company early adopted this ASU as of the beginning of fiscal year 2016 and made an election to recognize forfeitures as they occur. The ASU adoption was applied using a modified retrospective method by means of a $1.7 million cumulative-effect adjustment to accumulated earnings as of the beginning of the fiscal year. In February 2016, the FASB issued a new accounting standard related to lease accounting, ASU No. 2016-02, Leases , which will result in lessees recognizing most leases on the balance sheet. Lessees are required to disclose more quantitative and qualitative information about their leases than current U.S. GAAP requires. The ASU is effective for public entities for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2018. As of October 1, 2016 and January 2, 2016, the Company’s undiscounted minimum contractual commitments under long-term operating leases, which were not recorded on the balance sheet, were $28.6 million and $21.9 million, respectively, which is an estimate of the effect to lease obligations and property, plant and equipment that the new accounting standard would have as of the dates noted. In May 2014, the FASB issued a new accounting standard to improve and converge the financial reporting requirements for revenue from contracts with customers. ASU No. 2014-09, Revenue from Contracts with Customers , prescribes a five-step model for revenue recognition that will replace most existing revenue recognition guidance in U.S. GAAP. The ASU will supersede nearly all existing revenue recognition guidance under U.S. GAAP and provides that an entity 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. This update also requires additional disclosure about the nature, amount, timing and uncertainty of revenue and cash flows arising from customer contracts, including significant judgments and changes in judgments, and assets recognized from costs incurred to obtain or fulfill a contract. ASU No. 2014-09 allows for either full retrospective or modified retrospective adoption. In July 2015, the FASB postponed the effective date of the new revenue standard by one year to the first quarter of 2018. Early adoption is permitted, but no earlier than 2017. Management is currently assessing the effect that the adoption of this standard will have on the consolidated financial statements.

Company Information
Initial Public Offering	Summit Inc.’s Equity Offerings — Summit Inc. commenced operations on March 11, 2015 upon the pricing of the initial public offering of its Class A common stock (“IPO”). Summit Inc. raised $433.0 million, net of underwriting discounts, through the issuance of 25,555,555 shares of Class A common stock at a public offering price of $18.00 per share. Summit Inc. used the offering proceeds to purchase a number of newly-issued Class A Units (“LP Units”) from Summit Holdings equal to the number of shares of Class A common stock issued to the public. Summit Inc. caused Summit Holdings to use these proceeds: (i) to redeem $288.2 million in aggregate principal amount of outstanding 10 1 / 2 % senior notes due January 31, 2020 (“2020 Notes”); (ii) to purchase 71,428,571 Class B Units of Continental Cement Company, L.L.C. (“Continental Cement”); (iii) to pay a one-time termination fee of $13.8 million primarily to affiliates of the Sponsors in connection with the termination of a transaction and management fee agreement; and (iv) for general corporate purposes. The $288.2 million redemption of 2020 Notes was completed in the second quarter of 2015 at a redemption price equal to par plus an applicable premium of $38.2 million plus $5.2 million of accrued and unpaid interest. In connection with the IPO, Summit Inc. issued 69,007,297 shares of its Class B common stock to Summit Owner Holdco LLC (“Summit Owner Holdco”), a Delaware limited liability company owned by certain pre-IPO owners and the former holders of Class B Units of Continental Cement. The Class B common stock entitled Summit Owner Holdco, without regard to the number of shares of Class B common stock held by it, to a number of votes that is equal to the aggregate number of LP Units held by all limited partners of Summit Holdings (excluding Summit Inc.). On July 19, 2016, Summit Owner Holdco transferred 28,661,526 shares of its Class B common stock to certain holders of LP Units and the remaining 40,345,771 shares of Class B common stock were cancelled. The Class B common stock entitles holders thereof, who are also holders of LP Units, with a number of votes that is equal to the number of LP Units they hold. The Class B common stock does not participate in dividends and does not have any liquidation rights.
Follow-On Offering	On August 11, 2015, Summit Inc. raised $555.8 million, net of underwriting discounts, through the issuance of 22,425,000 shares of Class A common stock at a public offering price of $25.75 per share ("the August 2015 follow-on offering"). Summit Inc. used these proceeds to purchase 3,750,000 newly-issued LP Units from Summit Holdings and 18,675,000 LP Units from certain pre-IPO owners, at a purchase price per LP Unit equal to the public offering price per share of Class A common stock, less underwriting discounts and commissions. Summit Holdings used the proceeds from the 3,750,000 newly-issued LP Units to pay the deferred purchase price of $80.0 million related to the July 17, 2015 acquisition of a cement plant and quarry in Davenport, Iowa, and seven cement terminals along the Mississippi River (the “Davenport Assets”) and for general corporate purposes.
Basis of Presentation	Basis of Presentation —These unaudited consolidated financial statements were prepared in accordance with U.S. generally accepted accounting principles (“U.S. GAAP”) for interim financial information, without audit, pursuant to the rules and regulations of the Securities and Exchange Commission. Certain information and footnote disclosures typically included in financial statements prepared in accordance with U.S. GAAP have been condensed or omitted pursuant to such rules and regulations. These unaudited consolidated financial statements should be read in conjunction with the Company’s audited consolidated financial statements and the notes thereto as of and for the year ended January 2, 2016. The Company continues to follow the accounting policies set forth in those consolidated financial statements. Management believes that these consolidated interim financial statements include all adjustments, normal and recurring in nature, that are necessary to present fairly the financial position of the Company as of October 1, 2016, the results of operations for the three and nine months ended October 1, 2016 and September 26, 2015 and cash flows for the nine months ended October 1, 2016 and September 26, 2015. The Company’s fiscal year is based on a 52-53 week year with each quarter composed of 13 weeks ending on a Saturday. The 53-week year occurs approximately once every seven years and occurred in 2015. The additional week in the 53-week year was included in the fourth quarter of 2015.
Principles of Consolidation	Principles of Consolidation –The consolidated financial statements include the accounts of Summit LLC and its majority owned subsidiaries. All intercompany balances and transactions have been eliminated. The Company attributes consolidated member’s interest and net income separately to the controlling and noncontrolling interests. Noncontrolling interests in consolidated subsidiaries represent a 20% ownership in Ohio Valley Asphalt, LLC and, prior to the IPO and concurrent purchase of the noncontrolling interests of Continental Cement, a 30% redeemable ownership in Continental Cement. The Company accounts for investments in entities for which it has an ownership of 20% to 50% using the equity method of accounting.
Use of Estimates	Use of Estimates — Preparation of these consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions. These estimates and the underlying assumptions affect the amounts of assets and liabilities reported, disclosures about contingent assets and liabilities and reported amounts of revenue and expenses. Such estimates include the valuation of accounts receivable, inventories, goodwill, intangibles and other long-lived assets, pension and other postretirement obligations and asset retirement obligations. Estimates also include revenue earned on contracts and costs to complete contracts. Most of the Company’s paving and related services are performed under fixed unit-price contracts with state and local governmental entities. Management regularly evaluates its estimates and assumptions based on historical experience and other factors, including the current economic environment. As future events and their effects cannot be determined with precision, actual results can differ significantly from estimates made. Changes in estimates, including those resulting from continuing changes in the economic environment, are reflected in the Company’s consolidated financial statements when the change in estimate occurs.
Business and Credit Concentrations	Business and Credit Concentrations— The Company’s operations are conducted primarily across 24 U.S. states and in British Columbia, Canada, with the most significant revenue generated in Texas, Kansas, Utah, Missouri and Kentucky. The Company’s accounts receivable consist primarily of amounts due from customers within these areas. Therefore, collection of these accounts is dependent on the economic conditions in the aforementioned states, as well as specific situations affecting individual customers. Credit granted within the Company’s trade areas has been granted to many customers, and management does not believe that a significant concentration of credit exists with respect to any individual customer or group of customers. No single customer accounted for more than 10% of the Company’s total revenue in the three and nine months ended October 1, 2016 and September 26, 2015.
Fair Value Measurements	Fair Value Measurements— Certain acquisitions made by the Company require the payment of contingent amounts of purchase consideration. These payments are contingent on specified operating results being achieved in periods subsequent to the acquisition and will only be made if earn-out thresholds are achieved. Contingent consideration obligations are measured at fair value each reporting period. Any adjustments to fair value are recognized in earnings in the period identified. The Company has entered into interest rate derivatives on $200.0 million of its term loan borrowings to add stability to interest expense and to manage its exposure to interest rate movements. The effective portion of changes in the fair value of derivatives designated and that qualify as cash flow hedges is recorded in accumulated other comprehensive income and will be subsequently reclassified into earnings in the period that the hedged forecasted transaction affects earnings. The fair value of contingent consideration and derivatives as of October 1, 2016 and January 2, 2016 was: October 1, January 2, 2016 2016 Current portion of acquisition-related liabilities and Accrued expenses: Contingent consideration $ $ Cash flow hedges Acquisition-related liabilities and Other noncurrent liabilities Contingent consideration $ $ Cash flow hedges The fair value of contingent consideration was based on unobservable, or Level 3, inputs, including projected probability-weighted cash payments and an 11.0% discount rate, which reflects a market discount rate. Changes in fair value may occur as a result of a change in actual or projected cash payments, the probability weightings applied by the Company to projected payments or a change in the discount rate. Significant increases or decreases in any of these inputs in isolation could result in a lower, or higher, fair value measurement. The fair value of the cash flow hedges are based on observable, or Level 2, inputs such as interest rates, bond yields and prices in inactive markets. There were no material valuation adjustments to the derivatives in the three and nine months ended October 1, 2016 and September 26, 2015 and approximately $4.1 million of adjustments to contingent consideration in the nine months ended October 1, 2016.
Financial Instruments	Financial Instruments —The Company’s financial instruments include debt and certain acquisition-related liabilities (deferred consideration and noncompete obligations). The carrying value and fair value of these financial instruments as of October 1, 2016 and January 2, 2016 was: October 1, 2016 January 2, 2016 Fair Value Carrying Value Fair Value Carrying Value Level 2 Long-term debt(1) $ $ $ $ Level 3 Current portion of deferred consideration and noncompete obligations(2) Long term portion of deferred consideration and noncompete obligations(3) (1) Balances include $6.5 million of current portion of debt and exclude capitalized loan costs of $15.6 million and $11.7 million as of October 1, 2016 and January 2, 2016, respectively. (2) Included in current portion of acquisition-related liabilities on the consolidated balance sheets. (3) Included in acquisition-related liabilities on the consolidated balance sheets. The fair value of debt was determined based on observable, or Level 2 inputs, such as interest rates, bond yields and quoted prices in inactive markets. The fair values of the deferred consideration and noncompete obligations were determined based on unobservable, or Level 3, inputs, including the cash payment terms in the purchase agreements and a discount rate reflecting the Company’s credit risk.
Redeemable Noncontrolling Interest	Redeemable Noncontrolling Interest — On March 17, 2015, upon the consummation of the IPO and the transactions contemplated by a contribution and purchase agreement entered into with the holders of all of the outstanding Class B Units of Continental Cement, Continental Cement became a wholly-owned indirect subsidiary of Summit LLC. The noncontrolling interests of Continental Cement were acquired for aggregate consideration of $64.1 million, consisting of $35.0 million of cash, 1,029,183 shares of Summit Inc.’s Class A common stock and $15.0 million aggregate principal amount of non-interest bearing notes payable in six annual installments of $2.5 million, beginning on March 17, 2016. The notes payable is a liability of Summit Holdings and, is therefore not included in the liabilities of Summit LLC. However, Summit LLC made a $2.5 million distribution to Summit Holdings in the nine months ended October 1, 2016 so that Summit Holdings could make the deferred consideration payment due on March 17, 2016.
New Accounting Standards	New Accounting Standards — In March 2016, the Financial Accounting Standards Board (“FASB”) issued a new accounting standard with targeted amendments to the accounting for employee share-based payments. Accounting Standards Update (“ASU”) 2016-09, Improvements to Employee Share-Based Payment Accounting , requires that the income tax effect of share-based awards be recognized in the income statement and allows entities to elect an accounting method to recognize forfeitures as they occur or to estimate forfeitures, as is currently required. The ASU is effective for public entities for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2016. However, the Company early adopted this ASU as of the beginning of fiscal year 2016 and made an election to recognize forfeitures as they occur. The ASU adoption was applied using a modified retrospective method by means of a $1.7 million cumulative-effect adjustment to accumulated deficit as of the beginning of the fiscal year. In February 2016, the FASB issued a new accounting standard related to lease accounting, ASU No. 2016-02, Leases , which will result in lessees recognizing most leases on the balance sheet. Lessees are required to disclose more quantitative and qualitative information about their leases than current U.S. GAAP requires. The ASU is effective for public entities for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2018. As of October 1, 2016 and January 2, 2016, the Company’s undiscounted minimum contractual commitments under long-term operating leases, which were not recorded on the balance sheet, were $28.6 million and $21.9 million, respectively, which is an estimate of the effect to lease obligations and property, plant and equipment that the new accounting standard would have as of the dates noted.

ASU No. 2014-09 allows for either full retrospective or modified retrospective adoption. In July 2015, the FASB postponed the effective date of the new revenue standard by one year to the first quarter of 2018. Early adoption is permitted, but no earlier than 2017. Management is currently assessing the effect that the adoption of this standard will have on the consolidated financial statements.
