[1]Balance sheet exposure is denominated in U.S. Dollars and denotes the mark-to-market impact of the derivative financial instruments on the reporting date.
[2]Notional amounts are key elements of derivative financial instrument agreements, but do not represent the amount exchanged by counterparties and do not measure the Company's exposure to credit or market risks. However, the amounts exchanged are based on the notional amounts and other provisions of the underlying derivative financial instruments agreements.
