A bank has the following balance sheet: 000 Assets Avg Rate Liabilities/Equity Avg Rate Rate sensitive $350,000 7.75% Rate sensitive $475,000 6.25% Fixed rate 955,000 8.75 Fixed rate 805,000 7.50 Nonearning 765.000 Nonpaying 790,000 Total $2,070,000 Total $2,070,000 Suppose interest rates fall such that the average yield on rate-sensitive assets decreases by 15 basis points and the average yield on rate-sensitive liabilities decreases by 5 basis points. a) Calculate the bank's CGAP, gap to total assets and gap ratio. b) Assuming the bank does not change the composition of its balance sheet, calculate the resulting change in the bank's interest income, interest expense, and net interest income. c) Explain how the CGAP and spread effects influenced this change in net interest income. 3.
