TWC issues bullet bonds at 8%, with a ten-year maturity, company will recognize holders of securities in amount of $ 1,000. With this information assume that changes and valuation will occur at end of first period. Solve this exercise under following considerations:

Po=i(1+i)nC[(1+i)n1]+(1+in)nNV

Po=(1+i)1C1+(1+i)2C2+......+(1+i)nCn+(1+i)nNV

1. Estimate value of bonds under following guidelines: (a) At nominal or face rate.  b) Assuming that market interest 10%, and c) Assuming a market interest of 6%.
