[1] For the six months ended June 30, 2017, there was a revision to net earnings from discontinued operations, net of tax, on the Condensed Consolidated Statement of Operations related to depreciation and amortization on Diversey assets held for sale. Refer to Note 4, "Discontinued Operations, Divestitures and Acquisitions", for additional information.

[2] Due to the adoption of ASU 2016-18, the Company now is required to include restricted cash as part of the change in the total cash balance. As a result, amounts which were previously classified as cash flows from financing activities have been reclassified as they are recognized in the total change in cash. Refer to Note 2, "Recently Adopted and Issued Accounting Standards," in the Notes to Condensed Consolidated Financial Statements for more information.

[3] Restricted cash and cash equivalents included compensating balance deposits related to certain short-term borrowings.
