However, in case of a bullet bond, which is very much common and where principal is repaid in a lumpsum amount only on the maturity and not in instalments every year along with the interest payment, the cash flow each year (other than the final cash flow) will be inclusive of only interest payments and the final cash flow will include the interest and entire amount of principal. In such cases, the yield to maturity will be different.
