Final answer:
To determine the net interest margin, subtract the total interest expenses from the total interest income. To calculate the noninterest margin, subtract the total non-interest expenses from the total non-interest income. The earnings spread can be calculated by subtracting the interest expenses from the interest income.
Step-by-step explanation:
To determine the net interest margin, subtract the total interest expenses from the total interest income. In this case, the net interest margin would be 16 - 12 = 4. To calculate the noninterest margin, subtract the total non-interest expenses from the total non-interest income.
In this scenario, the noninterest margin would be 2 - 5 = -3. The earnings spread can be calculated by subtracting the interest expenses from the interest income. Thus, the earnings spread would be 16 - 12 = 4.
