 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:

•The change in NII due to volume is calculated as the change in average balance multiplied by the yield or rate from the prior period. 

•The change in NII due to yield or rate is calculated as the change in yield or rate multiplied by the average balance from the prior period. 

•The change in NII due to changes in both volume and yield or rate (i.e., portfolio mix) is calculated as the change in rate multiplied by the change in volume. This component is allocated between the changes due to volume and yield or rate based on the ratio each component bears to the absolute dollar amounts of their total. 

•Tax equivalent NII was not materially different from NII, therefore we present NII in our analysis.
