[1] Interest rate derivative losses are primarily from fair value hedges and are included in interest expense. These losses are substantially offset by decreases in the value of the underlying debt, which is also included in interest expense. All other gains/losses are from non-designated hedges and are included in corporate unallocated expenses.
[2] Interest rate derivative losses are included in interest expense. All other gains/losses are primarily included in cost of sales.
