Answer questions 1 to 3 for Micro Advantage
Below is information regarding the capital structure of Micro Advantage Inc. On the basis of this information you are asked to respond to the following three questions: Required: 1. Micro Advantage issued a $5,650,000 par value, 19-year bond a year ago at 96 (i.e., 96% of par value) with a stated rate of 10%. Today, the bond is selling at 115 (.e., 115% of par value). If the firm's tax bracket is...
