Net Interest Income and Net Interest Margin 

NII is affected by changes in interest rates and changes in the amount and composition of interest-earning assets and interest-bearing liabilities. Interest income and expense and the respective yields and rates include amortization of premiums, accretion of discounts, and impacts from hedging activities. 

The following tables present the average balances of interest-earning assets and interest-bearing liabilities with the associated yields and rates, interest income and expense, and changes therein due to changes in volume and yields or rates. Changes in interest income and expense due to changes in (i) volume (average balances of interest-earning assets and interest-bearing liabilities) and (ii) yields or rates are based on the following:
