Organization, Consolidation and Presentation of Financial Statements [Abstract]

BASIS OF PRESENTATION

BASIS OF PRESENTATION

The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles (GAAP) for interim financial information and the instructions to Form 10-Q. Accordingly, they do not include all of the information and footnotes required by U.S. GAAP for complete financial statements. In the opinion of management, all adjustments (consisting of normal recurring accruals) considered necessary for a fair presentation have been included.

There have been no significant changes in critical accounting policies since December 31, 2016. Accounting estimates were revised as necessary during the first nine months of 2017 based on new information and changes in facts and circumstances. Certain amounts in the 2016 condensed consolidated financial statements have been reclassified to conform to the 2017 presentation. See Note 14 for information on the changes in the Company's reportable segments.

The Company primarily uses the last-in, first-out (LIFO) method of valuing inventory. An actual valuation of inventory under the LIFO method can be made only at the end of each year based on the inventory levels and costs at that time. Accordingly, interim LIFO calculations are based on management’s estimates of expected year-end inventory levels and costs are subject to the final year-end LIFO inventory valuation. In addition, interim inventory levels include management’s estimates of annual inventory losses due to shrinkage and other factors. The final year-end valuation of inventory is based on a cycle count program or an annual physical inventory count performed during the third and fourth quarters. For further information on inventory valuations and other matters, refer to the consolidated financial statements and footnotes thereto included in the Company’s Form 10-K for the year ended December 31, 2016.

The consolidated results for the three and nine months endedSeptember 30, 2017 are not necessarily indicative of the results to be expected for the year ending December 31, 2017.
