. Aclosed fbrm approximation formula is derived for American cQupon bond options on the basis of the Geske − Johnson method under the assumption that the interes 七 rate follows the rational log − normal modeL Its strike − time discretization errors are esti − mated , and are found to be permissible as a rule , though they are larger than in the case of American stock options . The Geske − Johnson method would be available for estimating American interest rate options as well as fbr American
