[1] Amounts represent the impact of legally enforceable master netting agreements that allow the Company to settle positive and negative positions.

[2] The Company also offsets assets and liabilities associated with repurchase agreements on the Consolidated Balance Sheets. See Note 2 "Securities" to the Company's unaudited interim Consolidated Financial Statements included in Part I, Item 1 — Financial Information for further information.

[3] The notional or contractual amount of interest rate derivatives and foreign exchange contracts is the amount upon which interest and other payments under the contract are based. For interest rate derivatives, the notional amount is typically not exchanged. Therefore, notional amounts should not be taken as the measure of credit or market risk, as they tend to greatly overstate the true economic risk of these contracts.
