(1)Amounts presented in these columns are limited in total to the net amount of assets or liabilities presented in the prior column by instrument. In certain cases, we have pledged excess cash collateral or financial assets to a counterparty (which, in certain circumstances, may be a clearinghouse) that exceed the financial liabilities subject to a master netting arrangement or similar agreement. Additionally, in certain cases, counterparties may have pledged excess cash collateral to us that exceeds our corresponding financial assets. In each case, these excess amounts are excluded from the table; they are separately reported in our consolidated balance sheets as assets or liabilities, respectively. (2)Interest rate agreements, TBAs and futures are components of derivative instruments on our consolidated balance sheets. Loan warehouse debt, which is secured by certain residential and business purpose loans, is a component of Short-term debt and Long-term debt on our consolidated balance sheets.
