SEGMENT INFORMATION

Grainger's two reportable segments are the U.S. and Canada. These reportable segments reflect the results of the Company's businesses in those geographies, except for Zoro Tools, Inc. (Zoro), which is in the U.S. Other businesses include the Company's single channel businesses (Zoro and MonotaRO in Japan) and small operations in Europe, Asia and Latin America. These businesses individually do not meet the criteria of a reportable segment.

Segment and total consolidated operating earnings for the three and nine months ended September 30, 2017 were restated for the implementation of ASU 2017-07. See Note 2 to the Financial Statements.

Unallocated expenses and eliminations primarily relate to the Company's headquarters support services and intercompany eliminations, which are not part of any reportable segment. Unallocated expenses are primarily comprised of employee compensation costs, depreciation and other administrative costs.

The Company is a broad-line distributor of MRO supplies, and other related products. 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.
