1. Loan Valuation and Analysis

2. Pure Discount Loans  Treasury bills are excellent examples of pure discount loans. The principal amount is repaid at some future date, without any periodic interest payments.  If a T-bill promises to repay $10,000 in 1 year and the market interest rate is 7 percent, how much will the bill sell for in the market? –PV = 10,000 / 1.07 = 9345.79

3. Interest Only Loan  Consider a 5-year, interest only loan with a 7% interest rate. The principal amount is $10,000. Interest is paid annually. –What would the stream of cash flows be? Years 1 – 4: Interest payments of.07(10,000) = 700 Year 5: Interest + principal = 10,700  This cash flow stream is similar to the cash flows on corporate bonds and we will talk about them in greater detail later.

4. Amortized Loan with Fixed Payment  Amortized loan is the most common consumer loans, including mortgages, car loans, etc.  Since periodic payment is a fixed amount, an amortized loan is an annuity  Each payment covers the interest expense plus reduces the principal  Consider a 4 year loan with annual payments. The interest rate is 8% and the principal amount is $5000. –What is the annual payment? 5000 = C[1 – 1 / 1.08 4 ] /.08 C = 1509.60

5. Amortization Schedule  Beginning Principal Balance = previous beginning principal balance – previous principal component of payment  Periodic Payment: fixed, computed as an annuity  Interest component = Periodic interest rate x current beginning principal balance  Principal Component = Periodic Payment – Interest component

7. Payment Frequencies  Remember to convert interest rate and terms to the appropriate frequency  Example: 30 year fixed rate mortgage at 6% per year with monthly payments  Number of payments = 30 x 12 = 360  Interest per month = 6% / 12 = 0.5% per month
