Question

ng a to borrow $300,000 to be repaid in a lump sum at the end of nine years. Interest payments will be made on the loan at the end of each year. The company is considering the following three financing arrangements borrow the money using a fixed rate loan (FRL) that requires interest payments of 9% per year each of the first five years. At the beginning of the sixth year, the The company can borrow interest rate on the loan could change to 7%, 9%, or 11% with probabilities of 0.1, 0.25, and 0.65 the money using an adjustable rate loan (ARL) that requires interest payments of 6% at the end of can borrow the money using an ARL that requires interest payments of 4% at the end of each of the first three years. At the beginning of the fourth year, the d dinge io to, e s, er ,0% with pribablites ir 0.05, 0.30, and 0.65, respectively. At the beginnng y of 0. of the seventh year, the interest rate could decrease by 1 percentage point with a 1, increase by 1 percentage point with a probability of 0.2, or increase by 3 percentage points with a probability of 0.7 a. Create a decision tree for this problem, computing the total interest paid under each possible scenario. Option 2 Option 3 20 8 9

Explanation / Answer

the principle amount is $300,000

option 1 with fixed interest rate is 9%= $300,000*0.09= $27,000, and for 9 years it is 27,000*9= $243,000

option 2= 6% for first 5 years, and next 7%, 9% and 11% with probabilities of 0.1, 0.25, and 0.65

the interest rate for second 4 years will be= 7*0.01+ 9*0.025+11*0.11= 0.07+ 0.225+7.15= 7.445

then the payment becomes= 300,000*0.06*5+ 300,000*0.07445*4= 90,000+89,340= 179,340

option 3= 4% for first 3 years= 300,000*0.04*3= 36,000

begining of 4th year, it changes as= 6* 0.05+8*0.30+ 10*0.65= 0.3+2.4+6.5= 9.2%

for next 3 years the interest rate is 9.2% and the payment is= 300,000*0.092*3= 82,800

for the last 3 years= (-1*0.01)+ (1*0.02)+ (3*0.07)= (0.01)+ .02+.0.21= 0.22 the interest rate increased by 0.22 than earlier level. the earlier year it is 9.2% and is increased by 0.22%.

now the interest rate for last 3 years is 9.22*1.22= 11.2484 (take it as 11.25%)

the payment is= 300,000*0.1125*3= 101,250

the payment for otpion 3 is= 101,250+82,800+36,000= 220,050

option 2 is the best alternative among these 3
