(1) Revenues by country are based on the location of shipping destination, and not whether the order originates in the United States parent or a foreign subsidiary.

(2) Other consists of foreign countries that each individually account for less than 10% of the total revenues or assets.

(3) Net long-lived assets include rental and lease equipment and other property, net of accumulated depreciation and amortization. Subsequent to the issuance of the May 31, 2012 consolidated financial statements, we determined that, for geographic disclosure purposes, the previously reported amount of net long-lived assets as of May 31, 2012 should not have included goodwill and other intangible assets (which totaled $4,310 at that date) and, accordingly, such amount has been excluded from the May 31, 2012 balance displayed in the table above.
