Answer:
YTM = 10.53%
YTC = 14.36%
Step-by-step explanation:
the yield to maturity (YTC) formula is:
YTM = {coupon + [(face value - market value)/n]} / [(face value + market value)/2]
YTM = {$45 + [($1,000 - $900)/20]} / [($1,000 + $900)/2] = $50 / $950 = 5.26 x 2 coupons per year = 10.53%
the yield to call (YTC) formula is:
YTC = {$45 + [($1,050 - $900)/6]} / [($1,050 + $900)/2] = $70 / $975 = 7.179 x 2 = 14.36%
