AMR is the parent company of American Airlines. In addition to its primary subsidiary, AMR also operates several airline support companies such as the SABRE group (reservations), the Management Services Group, and American Eagle (a regional carrier). American Airlines is currently considering the issuance of a series of $1,000 par bonds. The coupon rate offered, based on current market interest rates and the Standard & Poor's based AMR bond rating, will be 10%. The current interest rate is coincidentally 10% as well. Interest on the bonds will be paid semi-annually. However, American cannot decide on the maturity of the new issue. The life of the bonds will be 10, 20, or 30 years.
