 of interest-earning assets and interest-bearing liabilities, as well as changes in average yields/rates. Table 4 shows the effect that these factors had on the interest earned from our interest-earning assets and interest incurred on our interest-bearing liabilities. The effect of changes in volume is determined by multiplying the change in volume by the current period’s average yield/rate. The effect of rate changes is calculated by multiplying the change in average yield/rate by the previous period’s volume. Changes not solely attributable to volume or yields/rates have been allocated in proportion to the respective volume and yield/rate components.
