Apple recently issued 15 yr bonds at $950 per share. These bonds pay $25 coupons every 6 months. Their price has remained stable since they were issued, i.e., they still sell for $950 share today. Due to additional financing needs, the firm wishes to issue new bonds that would have a maturity of 15 yrs, a par value of $1,000, and it will pay $20 coupons every 6 months. If both bonds have the same yield to maturity, how many shares of new bonds must Apple issue today to raise $2,188,000 cash today?
