REVENUE [Abstract] |
REVENUE | REVENUE Grainger serves a large number of customers in diverse industries, which are subject to different economic and market-specific factors. The Company's revenue is primarily comprised of MRO product sales and related activities. The Company's presentation of revenue by segment and customer industry most reasonably depicts how the nature, amount, timing and uncertainty of the Company's revenue and cash flows are affected by economic and market-specific factors. The majority of Company revenue originates from contracts with a single performance obligation to deliver products, whereby performance obligations are satisfied when control of the product is transferred to the customer per the arranged shipping terms. The following tables present the Company's percentage of revenue by reportable segment and by customer industry:
