[1] Transactions were not recorded in the correct legal entity, and the amounts were not properly reclassified to the correct column.

[2] Clerical errors led to misclassifications between columns and between line items.

[3] Intercompany amounts related to the receivables securitization program discussed in Note 16 were not correctly calculated or reported.

[4] Cash flows related to intercompany loans and investments were all included in a single line in cash flows from investing activities instead of separately identified and classified by transaction type in cash flows from operating, investing, and financing activities.
