[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 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.

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