The yield to call would be the internal rate of return considering the cahsflow until the bodn is called. W can solve for that using excel IRR function;
We list the cashflow in order.
F0 -1180
F1 105
F2 105
F3 105
F4 105
F5 1205 (105 coupon payment plus 1100 principal)
We now write the function and get the YTC
=IRR(B1:B6) 7.7366%
