The assignment presents a detailed case study of loan refinancing. It involves calculating the monthly payment for an existing 20 million dollar loan at 8% interest, determining the interest and principal portions of the first payment, and projecting the outstanding loan balance after three years. It further explores the benefits of refinancing by comparing the present value of the remaining loan at 7% interest with the original loan terms. The assignment also calculates quarterly payments for a similar loan scenario and determines the effective annual rate. Finally, it recommends whether or not to refinance the loan based on the calculated NPV.
