This morning, Wapiti Bank received $4,000,000 in cash for a certificate of deposit. This CD has a 3-year maturity and an 8% annual cost. It only makes payments at maturity. Wapiti Bank used the proceeds from this CD, plus equity, to make a 4-year loan to a start-up bio-tech company. Wapiti Bank gave out $5,000,000 in cash this morning. This loan was priced at an 8% yield-to-maturity (YTM) and will be paid back to Wapiti Bank in 4 equal, annual installments (fully amortizing) at the end of each of the next 4 years. These are the only two securities that Wapiti Bank has, other than equity.
