[1] 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 related to Sealed Air continuing operations and amounts which were previously classified as cash flows from investing activities related to restricted cash sold with the sale of Diversey have been reclassified as they are recognized in the total change in cash. Refer to Note 2, "Recently Adopted and Issued Accounting Standards," of the Notes to Consolidated Financial Statements for more information.
