Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation and Principles of Consolidation	Basis of Presentation and Principles of Consolidation The accompanying unaudited condensed consolidated balance sheet as of June 30, 2018 , the unaudited condensed consolidated statements of operations and comprehensive income for the three and six months ended June 30, 2018 and 2017 , and the unaudited condensed consolidated statements of cash flows for the six months ended June 30, 2018 and 2017 , have been prepared in accordance with the requirements of the U.S. Securities and Exchange Commission (“SEC”) for interim reporting. Accordingly, certain footnotes and other financial information that are normally required by generally accepted accounting principles in the U.S. (“GAAP”) have been condensed or omitted. The unaudited condensed consolidated balance sheet as of December 31, 2017 has been derived from the Company’s audited financial statements, which are included in its 2017 Annual Report on Form 10-K filed with the SEC on March 1, 2018 . The unaudited condensed consolidated interim financial statements should be read in conjunction with the Company’s audited consolidated financial statements in its Annual Report on Form 10-K for the year ended December 31, 2017 . The unaudited condensed consolidated interim financial statements include all adjustments necessary for the fair presentation of the Company's consolidated results of operations, financial position, comprehensive income and cash flows. Results for the interim periods are not necessarily indicative of results to be expected for the full year or any other future periods. All intercompany balances and transactions have been eliminated in the unaudited condensed consolidated interim financial statements. Certain prior period amounts included in the consolidated financial statements have been reclassified to conform to the current period presentation. Adoption of ASC 606 On May 28, 2014, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") No. 2014-09, Revenue from Contracts with Customers : (Topic 606) ("ASU 2014-09"), to supersede nearly all existing revenue recognition guidance under U.S. GAAP. The Company adopted this pronouncement using the modified retrospective method effective January 1, 2018. Pursuant to Topic 606, revenue is recognized when promised goods or services are transferred to customers in an amount that reflects the consideration that is expected to be received for those goods or services. The Company reviewed the following areas: (i) presentation of certain items, including excise taxes on a gross or net basis; (ii) deferral and amortization of contract fulfillment costs; (iii) recognition of contract assets and liabilities for certain contracts that are performed but not completed; and (iv) timing of recognition of variable consideration received from vendors and paid to customers. The adoption of this pronouncement did not have any material impacts related to the above-noted areas, nor any impact to opening retained earnings as of January 1, 2018. Additionally, there were no material impacts on the amount and timing of revenue recognized in the Company's consolidated financial statements. Revenue Recognition A contract with a customer exists when a customer invoice is generated. The Company considers each item on an invoice as an individual performance obligation. The Company recognizes revenue for each performance obligation when ordered items are delivered, control is transferred, and legal right of ownership passes to the customer. The Company continues to include fees charged to customers for shipping and handling activities in net sales and the related costs in cost of goods sold upon transfer of control of ordered products to a customer. Revenues will also continue to be reported net of customer incentives, discounts and returns, including an allowance for estimated returns. The allowance for sales returns is calculated based on the Company’s returns experience, which has historically not been significant. The Company also earns management service fee revenue from operating third-party distribution centers belonging to certain customers. These revenues represented less than 1% of the Company's total net sales for the three and six months ended June 30, 2018 . Service fee revenue is recognized as earned on a monthly basis in accordance with the terms of the management service fee contracts and is included in net sales on the accompanying condensed consolidated statements of operations. See Note 12 - Segment and Geographic Information for the disaggregation of net sales for each of the two geographic areas in which the Company operates and also by major product category. Customers ’ Sales Incentives The Company also provides consideration to customers, such as sales allowances or discounts to its customers on a regular basis. Under ASU 2014-09, these customers’ sales incentives are recorded as a reduction to net sales as the sales incentive is earned by the customer. Customer sales incentives include volume-based rebates that are accounted for as variable consideration. Additionally, the Company may provide allowances for the customers' commitments to continue using Core-Mark as the supplier. These incentives are known as racking allowances. These allowances may be paid at the inception of the agreement or on a periodic basis. Allowances paid at the inception of the agreement are deferred and amortized over the period of the distribution agreement as a reduction to sales. Excise Taxes As part of the implementation of ASU 2014-09, the Company determined it is primarily responsible for collecting and remitting state, local and provincial excise taxes on cigarette and other tobacco products and will continue to present excise taxes as part of revenue and remittances as part of cost of goods sold. These excise taxes are a significant component of the Company’s net sales and cost of goods sold. Additionally, federal excise taxes are levied on the manufacturers who, in turn, pass the tax on to the Company as part of the product cost. As a result, federal excise taxes are not a component of the Company’s excise taxes. Contract Costs Under ASU 2014-09, contract costs such as future business expansion and integration costs with customers may be capitalized when they are considered to generate or enhance resources of the Company that will be used in satisfying its performance obligations in the future. These capitalized costs may include customer-specific hiring and training expenses and personnel-related customer information technology costs. Any capitalized costs will be amortized over the initial term of the customer agreement. Costs to obtain and fulfill customer contracts were not material as of January 1, 2018, or for the three and six months ended June 30, 2018 . Adoption of Other Accounting Pronouncements On March 10, 2017, the FASB issued ASU No. 2017-07, Compensation - Retirement Benefits (Topic 715): Improving the Presentation of Net Periodic Pension Cost and Benefit Cost . The Company adopted this pronouncement effective January 1, 2018. The new guidance requires employers that sponsor defined benefit pension and other post retirement plans to present the service cost component of net benefit cost in the same income statement line item as other employee compensation costs arising from services rendered. The other components of the net periodic benefit cost must be presented separately from the line item that includes the service cost component and outside of the income from operations subtotal. Service cost will continue to be recognized in the Company’s consolidated statements of operations within selling, general and administrative expenses. This change had no impact on consolidated net income. The reclassification of other components of net periodic benefit costs were not material for the Company with the exception of the non-cash pension termination charge during the fourth quarter of 2017 related to the termination of the defined-benefit pension plan. The 2017 pension termination charge will be reclassified in the fourth quarter of 2018 from selling, general and administrative expenses to a new financial statement line item, “Pension Termination Charge.” On February 14, 2018, the FASB issued ASU No. 2018-02, Income Statement - Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income (“ASU 2018-02”). ASU 2018-02 addresses the income tax accounting treatment of the stranded tax effects within other comprehensive income due to the newly enacted federal corporate tax rate included in the 2017 Tax Cuts and Jobs Act. The Company adopted this pronouncement on a prospective basis effective January 1, 2018 and it did not have a material impact for the Company. Additionally, ASU 2018-02 requires disclosure of the Company’s existing policy of releasing income tax effects from Accumulated Other Comprehensive Income as individual items are adjusted. Recent Accounting Standards or Updates Not Yet Effective On February 25, 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842) (“ASU 2016-02”), which supersedes existing lease guidance. The new guidance requires lessees to recognize right-of-use assets and corresponding lease liabilities, which the Company believes will have a material impact on its consolidated balance sheets. The Company is currently evaluating the adoption of this ASU, including the impact it will have on its financial statements and internal controls, as well as several practical expedients which are permitted related to the adoption. In addition, the Company is in the process of implementing software to assist with future reporting. As of December 31, 2017, the Company had $363.9 million of minimum future lease commitments under non-cancelable lease agreements, which primarily pertain to warehouse facilities and vehicles. A substantial portion of these minimum future lease commitments will be subject to ASU 2016-02 once adopted. This standard is effective for annual periods beginning after December 15, 2018, although early adoption is permitted. The Company expects to adopt ASU 2016-02 in fiscal 2019 using the modified retrospective approach. On January 26, 2017, the FASB issued ASU No. 2017-04, Intangibles - Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment (“ASU 2017-04”). The new guidance simplifies the subsequent measurement of goodwill by eliminating Step 2 from the goodwill impairment test. ASU 2017-04 requires goodwill impairment to be measured as the amount by which a reporting unit’s carrying amount exceeds its fair value, not to exceed the carrying amount of its goodwill. ASU 2017-04 requires prospective application and is effective for annual periods beginning after December 15, 2019. ASU 2017-04 will require the Company to amend its methodology for determining any goodwill impairment calculations beginning in 2020. Concentration of Credit Risks Financial instruments, which potentially subject the Company to concentrations of credit risk, consist principally of cash investments, accounts receivable and other receivables. The Company places its cash and cash equivalents in short-term instruments with high-quality financial institutions and limits the amount of credit exposure in any one financial instrument. The Company pursues amounts and incentives due from vendors in the normal course of business and is often allowed to deduct these amounts and incentives from payments made to vendors. A credit review is completed for new customers and ongoing credit evaluations of each customer’s financial condition are performed periodically, with reserves maintained for potential credit losses. Credit limits given to customers are based on a risk assessment of their ability to pay and other factors. Accounts receivable are typically not collateralized, but the Company may require prepayments or other guarantees whenever deemed necessary. Murphy U.S.A., the Company's largest customer, accounted for approximately 12% of the Company’s net sales for the three and six months ended June 30, 2018 and approximately 13% of the Company’s net sales for the three and six months ended June 30, 2017 . No other customers individually accounted for more than 10% of sales for these periods. No single customer accounted for 10% or more of the Company’s accounts receivables as of June 30, 2018 or December 31, 2017

Business Combinations [Abstract]
Acquisition	Acquisition On July 10, 2017 , the Company completed the acquisition of substantially all of the assets of Farner-Bocken Company ("Farner-Bocken"), a regional convenience wholesaler headquartered in Carroll, Iowa. The acquisition increased the Company’s market presence primarily in the Midwestern U.S. and has further enhanced the Company’s ability to cost effectively service national and regional retailers. The acquisition was accounted for as a business combination in accordance with ASC 805 - Business Combinations . The total purchase consideration was approximately $174.0 million , of which $169.0 million was paid at closing. The remaining $5.0 million indemnity holdback will be released in annual installments over two years from the date of the agreement, less amounts related to indemnification claims made pursuant to the purchase agreement, if any. In July 2018, the Company released $2.5 million as the first annual installment against the indemnity holdback. The acquisition was funded through borrowings under the Company's revolving credit facility. The fair values of the assets acquired and liabilities assumed were determined using the income, cost and market approaches. The following table presents the assets acquired and liabilities assumed, based on their fair values and purchase consideration as of the acquisition date (in millions): July 10, 2017 Accounts receivable $ 43.2 Other receivables 0.4 Inventories 35.5 Deposits and prepayments 10.2 Property and equipment 43.1 Goodwill (tax deductible) 36.8 Other intangible assets 22.6 Less: Capital lease liability (15.8 ) Less: Accrued liabilities and other (2.0 ) Total consideration $ 174.0 Based on the valuation, intangible assets acquired include the following (in millions): Fair Value Useful Life in Years Customer relationships $ 19.7 9-11 Non-competition agreements 0.1 4-6 Trade names 2.8 1-2 Total other intangible assets $ 22.6 The results of Farner-Bocken's operations have been included in the Company’s unaudited condensed consolidated interim financial statements since the date of acquisition. Simultaneous with the closing of the acquisition, the Company executed a capital lease for a warehouse facility in Carroll, Iowa. The lease had an initial 15 year term and, as of June 30, 2018 , a capital lease obligation of $15.0 million

Inventory Disclosure [Abstract]
Inventories, net	Inventories, net Inventories consist of the following (in millions): June 30, December 31, Inventories at FIFO, net of reserves $ 669.1 $ 841.0 Less: LIFO reserve (164.7 ) (151.9 ) Total inventories, net of reserves $ 504.4 $ 689.1 Cost of goods sold reflects the application of the last-in, first-out (“LIFO”) method of valuing inventories in the U.S. based upon estimated annual producer price indexes. Inventories in Canada are valued on a first-in, first-out (“FIFO”) basis, as LIFO is not a permitted inventory valuation method in Canada. During periods of rising prices, the LIFO method of costing inventories generally results in higher current costs being charged against income while lower costs are retained in inventories. Conversely, during periods of decreasing prices, the LIFO method of costing inventories generally results in lower current costs being charged against income and higher stated inventories. If the FIFO method had been used for valuing inventories in the U.S., inventories would have been approximately $164.7 million and $151.9 million higher as of June 30, 2018 and December 31, 2017 , respectively. The Company recorded LIFO expense of $6.9 million and $4.6 million for the three months ended June 30, 2018 and 2017 , respectively, and $12.8 million and $8.8 million

The Credit Facility expires in March 2022 and has an expansion feature which permits an increase of $200.0 million , subject to borrowing-base requirements. All obligations under the Credit Facility are secured by first-priority liens on substantially all of the Company’s present and future assets. The terms of the Credit Facility permit prepayment without penalty at any time (subject to customary breakage costs with respect to London Interbank Offered Rate ("LIBOR") or Canadian Dollar Offered Rate ("CDOR") based loans prepaid prior to the end of an interest period). Amounts borrowed, outstanding letters of credit and amounts available to borrow, net of certain reserves required under the Credit Facility, were as follows (in millions): June 30, December 31, Amounts borrowed $ 340.0 $ 488.2 Outstanding letters of credit 16.8 14.2 Amounts available to borrow (1) 330.0 152.1 ___________________________________________ (1) Excluding expansion feature of $200.0 million .

Employee Benefit Plans	Employee Benefit Plans The Company sponsored a qualified defined-benefit pension plan and a post-retirement benefit plan ("the Pension Plans"). The Pension Plans were frozen as of September 30, 1986, and since then there have been no new entrants to the Pension Plans. As of December 31, 2017, the Company had settled its qualified defined-benefit plan through annuities, and as a result had no pension costs for the three and six months ended June 30, 2018

Stock-based Compensation Plans	Stock-based Compensation Plans Grant Activities During the six months ended June 30, 2018 and 2017 , the Company granted 317,420 and 167,586 time-vesting restricted stock units to employees and non-employee directors under the 2010 Long-Term Incentive Plan at a weighted-average grant date fair value of $23.77 and $38.77 , respectively. For the six months ended June 30, 2018 , the Company granted 175,581 performance-based restricted stock units to certain of its employees at a weighted-average grant date fair value of $23.78 . The 175,581 performance shares represent the maximum number that can be earned. The number of performance shares that employees ultimately earn will be based on the Company’s achievement of certain specified performance targets for the full year of 2018 , to be measured in early 2019 . For the six months ended June 30, 2017 , the Company granted 126,220 performance-based shares to certain of its employees at a weighted-average grant date fair value of $39.34 , of which none were ultimately earned, and the shares were consequently forfeited. Stock-based Compensation Cost Total stock-based compensation cost included in selling, general and administrative expenses was $2.5 million and $1.2 million for the three months ended June 30, 2018 and 2017 , respectively. During the six months ended June 30, 2018 and 2017 , the Company recognized stock compensation cost of $4.4 million and $2.3 million , respectively. Total unrecognized compensation cost related to unvested share-based compensation arrangements was $12.9 million at June 30, 2018 , which is expected to be recognized over a weighted-average period of 2.2

Segment Reporting [Abstract]
Segment and Geographic Information	Segment and Geographic Information The Company identifies its operating segments based primarily on the way the Chief Operating Decision Maker (“CODM”) evaluates performance and makes decisions. The Chief Executive Officer of the Company has been identified as the CODM. From the perspective of the CODM, the Company is engaged primarily in the business of distributing packaged consumer products to convenience retail stores in the U.S. and Canada (collectively “North America”), which consists of customers that have similar characteristics. Therefore, the Company has determined that it has two operating segments, U.S. and Canada, that aggregate to one reportable segment. Additionally, the Company presents its segment reporting information based on business operations for each of the two geographic areas in which it operates and also by major product category. Information about the Company’s business operations based on geographic areas is as follows (in millions): Three Months Ended Six Months Ended June 30, June 30, 2018 2017 2018 2017 Net sales: United States $ 3,821.0 $ 3,445.2 $ 7,283.3 $ 6,635.3 Canada 391.5 347.5 722.8 650.6 Corporate (1) 14.0 8.0 26.3 19.0 Total $ 4,226.5 $ 3,800.7 $ 8,032.4 $ 7,304.9 Income before income taxes: United States $ 25.0 $ 12.6 $ 28.8 $ 15.6 Canada 2.5 2.4 3.2 4.1 Corporate (2) (12.1 ) (3.8 ) (18.4 ) (7.6 ) Total $ 15.4 $ 11.2 $ 13.6 $ 12.1 Interest expense, net: United States $ 13.4 $ 10.6 $ 27.2 $ 21.5 Canada 0.2 0.2 0.5 0.4 Corporate (3) (10.2 ) (8.8 ) (20.5 ) (18.0 ) Total $ 3.4 $ 2.0 $ 7.2 $ 3.9 Depreciation and amortization: United States $ 10.5 $ 8.7 $ 20.7 $ 17.4 Canada 0.6 0.6 1.2 1.2 Corporate (4) 3.7 2.9 7.7 5.7 Total $ 14.8 $ 12.2 $ 29.6 $ 24.3 Capital expenditures: United States $ 2.1 $ 16.5 $ 8.5 $ 29.9 Canada 0.2 0.6 0.7 0.9 Total $ 2.3 $ 17.1 $ 9.2 $ 30.8 ___________________________________________ (1) Consists primarily of external sales made by the Company’s consolidating warehouses, management service fee revenue, allowance for sales returns and certain other sales adjustments.

(3) Consists primarily of intercompany eliminations for interest. (4) Consists primarily of depreciation for the consolidation centers and amortization of intangible assets. Consolidation centers buy products from the Company’s suppliers in bulk quantities and then redistribute the products to many of its other distribution centers. Identifiable assets by geographic area are as follows (in millions): June 30, December 31, 2017 (1) Identifiable assets: United States $ 1,515.8 $ 1,630.9 Canada 112.0 151.6 Total $ 1,627.8 $ 1,782.5 ___________________________________________ (1) Subsequent to the issuance of the financial statements for the year ended December 31, 2017 , the Company identified an error in the previously reported identifiable assets between United States and Canada as of December 31, 2017 , which were previously reported as $1,510.5 million and $272.0 million , respectively. The Company has corrected the allocation of the prior period amounts in the table above. The correction was made in Q1 2018 and did not change previously reported total assets as of December 31, 2017 . The net sales mix for the Company’s primary product categories is as follows (in millions): Three Months Ended Six Months Ended June 30, June 30, Product Category 2018 2017 2018 2017 Cigarettes $ 2,842.7 $ 2,666.2 $ 5,380.2 $ 5,152.9 Food 426.9 363.3 818.4 698.3 Fresh 121.4 102.5 232.3 200.1 Candy 259.9 199.5 501.2 352.2 Other tobacco products 360.9 303.2 691.4 581.9 Health, beauty & general 160.5 118.0 312.0 236.1 Beverages 53.3 48.4 92.4 83.9 Equipment/other 0.9 (0.4 ) 4.5 (0.5 ) Total food/non-food products 1,383.8 1,134.5 2,652.2 2,152.0 Total net sales $ 4,226.5 $ 3,800.7 $ 8,032.4 $ 7,304.9

Basis of Presentation and Pri19

Basis of Presentation and Principles of Consolidation (Policies)	6 Months Ended

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Accounting	The accompanying unaudited condensed consolidated balance sheet as of June 30, 2018 , the unaudited condensed consolidated statements of operations and comprehensive income for the three and six months ended June 30, 2018 and 2017 , and the unaudited condensed consolidated statements of cash flows for the six months ended June 30, 2018 and 2017 , have been prepared in accordance with the requirements of the U.S. Securities and Exchange Commission (“SEC”) for interim reporting. Accordingly, certain footnotes and other financial information that are normally required by generally accepted accounting principles in the U.S. (“GAAP”) have been condensed or omitted. The unaudited condensed consolidated balance sheet as of December 31, 2017 has been derived from the Company’s audited financial statements, which are included in its 2017 Annual Report on Form 10-K filed with the SEC on March 1, 2018 . The unaudited condensed consolidated interim financial statements should be read in conjunction with the Company’s audited consolidated financial statements in its Annual Report on Form 10-K for the year ended December 31, 2017 .
Principles of Consolidation	All intercompany balances and transactions have been eliminated in the unaudited condensed consolidated interim financial statements.
Reclassification	Certain prior period amounts included in the consolidated financial statements have been reclassified to conform to the current period presentation.
Revenue Recognition, Customers' Sales Incentives, Excise Taxes, and Contract Costs	Revenue Recognition A contract with a customer exists when a customer invoice is generated. The Company considers each item on an invoice as an individual performance obligation. The Company recognizes revenue for each performance obligation when ordered items are delivered, control is transferred, and legal right of ownership passes to the customer. The Company continues to include fees charged to customers for shipping and handling activities in net sales and the related costs in cost of goods sold upon transfer of control of ordered products to a customer. Revenues will also continue to be reported net of customer incentives, discounts and returns, including an allowance for estimated returns. The allowance for sales returns is calculated based on the Company’s returns experience, which has historically not been significant. The Company also earns management service fee revenue from operating third-party distribution centers belonging to certain customers. These revenues represented less than 1% of the Company's total net sales for the three and six months ended June 30, 2018 . Service fee revenue is recognized as earned on a monthly basis in accordance with the terms of the management service fee contracts and is included in net sales on the accompanying condensed consolidated statements of operations. See Note 12 - Segment and Geographic Information for the disaggregation of net sales for each of the two geographic areas in which the Company operates and also by major product category. Customers ’ Sales Incentives The Company also provides consideration to customers, such as sales allowances or discounts to its customers on a regular basis. Under ASU 2014-09, these customers’ sales incentives are recorded as a reduction to net sales as the sales incentive is earned by the customer. Customer sales incentives include volume-based rebates that are accounted for as variable consideration. Additionally, the Company may provide allowances for the customers' commitments to continue using Core-Mark as the supplier. These incentives are known as racking allowances. These allowances may be paid at the inception of the agreement or on a periodic basis. Allowances paid at the inception of the agreement are deferred and amortized over the period of the distribution agreement as a reduction to sales. Excise Taxes As part of the implementation of ASU 2014-09, the Company determined it is primarily responsible for collecting and remitting state, local and provincial excise taxes on cigarette and other tobacco products and will continue to present excise taxes as part of revenue and remittances as part of cost of goods sold. These excise taxes are a significant component of the Company’s net sales and cost of goods sold. Additionally, federal excise taxes are levied on the manufacturers who, in turn, pass the tax on to the Company as part of the product cost. As a result, federal excise taxes are not a component of the Company’s excise taxes. Contract Costs Under ASU 2014-09, contract costs such as future business expansion and integration costs with customers may be capitalized when they are considered to generate or enhance resources of the Company that will be used in satisfying its performance obligations in the future. These capitalized costs may include customer-specific hiring and training expenses and personnel-related customer information technology costs. Any capitalized costs will be amortized over the initial term of the customer agreement. Costs to obtain and fulfill customer contracts were not material as of January 1, 2018, or for the three and six months ended June 30, 2018
Adoption of ASC 606, Adoption of Other Accounting Pronouncements, and Recent Accounting Standards or Updates Not Yet Effective	Adoption of Other Accounting Pronouncements On March 10, 2017, the FASB issued ASU No. 2017-07, Compensation - Retirement Benefits (Topic 715): Improving the Presentation of Net Periodic Pension Cost and Benefit Cost . The Company adopted this pronouncement effective January 1, 2018. The new guidance requires employers that sponsor defined benefit pension and other post retirement plans to present the service cost component of net benefit cost in the same income statement line item as other employee compensation costs arising from services rendered. The other components of the net periodic benefit cost must be presented separately from the line item that includes the service cost component and outside of the income from operations subtotal. Service cost will continue to be recognized in the Company’s consolidated statements of operations within selling, general and administrative expenses. This change had no impact on consolidated net income. The reclassification of other components of net periodic benefit costs were not material for the Company with the exception of the non-cash pension termination charge during the fourth quarter of 2017 related to the termination of the defined-benefit pension plan. The 2017 pension termination charge will be reclassified in the fourth quarter of 2018 from selling, general and administrative expenses to a new financial statement line item, “Pension Termination Charge.” On February 14, 2018, the FASB issued ASU No. 2018-02, Income Statement - Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income (“ASU 2018-02”). ASU 2018-02 addresses the income tax accounting treatment of the stranded tax effects within other comprehensive income due to the newly enacted federal corporate tax rate included in the 2017 Tax Cuts and Jobs Act. The Company adopted this pronouncement on a prospective basis effective January 1, 2018 and it did not have a material impact for the Company. Additionally, ASU 2018-02 requires disclosure of the Company’s existing policy of releasing income tax effects from Accumulated Other Comprehensive Income as individual items are adjusted. Recent Accounting Standards or Updates Not Yet Effective On February 25, 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842) (“ASU 2016-02”), which supersedes existing lease guidance. The new guidance requires lessees to recognize right-of-use assets and corresponding lease liabilities, which the Company believes will have a material impact on its consolidated balance sheets. The Company is currently evaluating the adoption of this ASU, including the impact it will have on its financial statements and internal controls, as well as several practical expedients which are permitted related to the adoption. In addition, the Company is in the process of implementing software to assist with future reporting. As of December 31, 2017, the Company had $363.9 million of minimum future lease commitments under non-cancelable lease agreements, which primarily pertain to warehouse facilities and vehicles. A substantial portion of these minimum future lease commitments will be subject to ASU 2016-02 once adopted. This standard is effective for annual periods beginning after December 15, 2018, although early adoption is permitted. The Company expects to adopt ASU 2016-02 in fiscal 2019 using the modified retrospective approach. On January 26, 2017, the FASB issued ASU No. 2017-04, Intangibles - Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment On May 28, 2014, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") No. 2014-09, Revenue from Contracts with Customers : (Topic 606)
Concentration of Credit Risks	Concentration of Credit Risks Financial instruments, which potentially subject the Company to concentrations of credit risk, consist principally of cash investments, accounts receivable and other receivables. The Company places its cash and cash equivalents in short-term instruments with high-quality financial institutions and limits the amount of credit exposure in any one financial instrument. The Company pursues amounts and incentives due from vendors in the normal course of business and is often allowed to deduct these amounts and incentives from payments made to vendors.
