Go to the FDIC website at www.fdic.gov and find the total amount of unused commitments and letters of credit and the notional value of interest rate swaps of FDIC-insured commercial banks for the most recent quarter available using the following steps. Click on “Analysts.” From there click on “Statistics on Banking.” Next click on “Assets and Liabilities” and “Run Report.” Select “Total Unused Commitments,” then “Letters of Credit,” and finally “Derivatives” to get the relevant data. This will bring the three files onto your computer that contain the relevant data. What is the dollar value increase in these amounts over the first-quarter 2012 values reported in Table 16–4 ?
