Definition of Bonds

Bonds are defined as securities issued by a business that requires regular interest payment to its holder. These are debt securities and offer regular income to its holder.

Present value of bond under first case – 6% yield to maturity

$\begin{array}{rcl}Presentvalueofbond& =& \left[CouponAmount\times \frac{1-{\displaystyle \frac{1}{{\left(1+Yieldrate\right)}^{Numverofyears}}}}{Yieldrate}\right]+\left[Amount\times \frac{1}{{\left(1+Yieldrate\right)}^{Numverofyears}}\right]\\ & =& \left[\$100\times \frac{1-{\displaystyle \frac{1}{{\left(1+0.06\right)}^{20}}}}{0.06}\right]+\left[\$1000\times \frac{1}{{\left(1+0.06\right)}^{20}}\right]\\ & =& \$1,147+\$312\\ & =& \$1,459\end{array}$

Present value of bond under the second case – 9% yield to maturity

$\begin{array}{rcl}Presentvalueofbond& =& \left[CouponAmount\times \frac{1-{\displaystyle \frac{1}{{\left(1+Yieldrate\right)}^{Numverofyears}}}}{Yieldrate}\right]+\left[Amount\times \frac{1}{{\left(1+Yieldrate\right)}^{Numverofyears}}\right]\\ & =& \left[\$100\times \frac{1-{\displaystyle \frac{1}{{\left(1+0.09\right)}^{20}}}}{0.09}\right]+\left[\$1000\times \frac{1}{{\left(1+0.09\right)}^{20}}\right]\\ & =& \$912.9+\$178\\ & =& \$1,090.90\end{array}$

Present value of bond under the third case – 13% yield to maturity

$\begin{array}{rcl}Presentvalueofbond& =& \left[CouponAmount\times \frac{1-{\displaystyle \frac{1}{{\left(1+Yieldrate\right)}^{Numverofyears}}}}{Yieldrate}\right]+\left[Amount\times \frac{1}{{\left(1+Yieldrate\right)}^{Numverofyears}}\right]\\ & =& \left[\$100\times \frac{1-{\displaystyle \frac{1}{{\left(1+0.13\right)}^{20}}}}{0.13}\right]+\left[\$1000\times \frac{1}{{\left(1+0.13\right)}^{20}}\right]\\ & =& \$7,02.5+\$87\\ & =& \$789.50\end{array}$
