MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL
CONDITION AND RESULTS OF OPERATIONS

Critical Accounting Policies and Estimates
The preparation of financial statements, in conformity with accounting principles generally accepted in the United States of America, requires management to make judgments, estimates and assumptions that affect the reported amounts of assets, liabilities, revenues and expenses in the financial statements. Management bases its estimates on historical experience and other assumptions, which it believes are reasonable. If actual amounts are ultimately different from these estimates, the revisions are included in Grainger’s results of operations for the period in which the actual amounts become known.

Accounting policies are considered critical when they require management to make assumptions about matters that are uncertain at the time the estimate is made and when different estimates than those management reasonably could have made have a material impact on the presentation of Grainger’s financial condition, changes in financial condition or results of operations. For a description of Grainger’s critical accounting policies see the Company’s Annual Report on Form 10-K for the year ended December 31, 2004.

Forward-Looking Statements
This document may contain forward-looking statements under the federal securities laws. The forward-looking statements relate to Grainger’s expected future financial results and business plans, strategies and objectives and are not historical facts. They are often identified by qualifiers such as “will,” “continue,” “believes,” “intends,” “expectations,” “expected,” “anticipate,” “estimate,” “assumption,” “may,” “potential,” “projection,” “depending” or similar expressions. There are risks and uncertainties the outcome of which could cause Grainger’s results to differ materially from what is projected.

Factors that may affect forward-looking statements include the following: higher product costs or other expenses; a major loss of customers; increased competitive pricing pressure on Grainger’s businesses; failure to develop or implement new technologies or other business strategies; the outcome of pending and future litigation and governmental proceedings; changes in laws and regulations; facilities disruptions or shutdowns; disruptions in transportation services; natural and other catastrophes; unanticipated weather conditions; and other difficulties in achieving or improving margins or financial performance.

Trends and projections could also be affected by general industry and market conditions, gross domestic product growth rates, general economic conditions, including industrial production, interest rate and currency rate fluctuations, global and other conflicts, job creation and employment levels in manufacturing, non-farm and other sectors, and other factors.
