SEGMENT INFORMATION

Grainger's two reportable segments are the U.S. and Canada. The U.S. reportable segment reflects the results of Grainger's U.S. businesses. The Canada reportable segment reflects the results for Acklands-Grainger, Inc. and its subsidiaries. Other businesses include the endless assortment businesses, Zoro Tools, Inc. (Zoro) in the U.S. and MonotaRO Co. (MonotaRO) in Japan, and smaller high-touch solutions businesses in Europe, Asia and Mexico. These businesses individually do not meet the criteria of a reportable segment.

The Company is a broad-line distributor of MRO products and services. Products are regularly added and deleted from the Company's inventory. Accordingly, it would be impractical to provide sales information by product category due to the way the business is managed.

Unallocated expenses primarily relate to the Company's headquarters support services and intercompany eliminations, which are not part of any reportable segment. Unallocated expenses include supply chain, product management and procurement, finance, communications, human resources, information systems, legal and compliance, internal audit and real estate.

Assets for reportable segments include net accounts receivable and first-in, first-out inventory which are reported to the Company's Chief Operating Decision Maker. Other current and non-current assets include all other assets of the reportable segments. Unallocated assets are primarily comprised of non-operating cash and cash equivalents, property, buildings and equipment, net, and certain prepaid expenses related to the Company's headquarters support services.
