In a recent article in this journal [6], Clement G. Krouse and Wayne Y. Lee (hereafter K-L) presented a model of optimal equity financing of a corporation based on Pontryagin's maximum principle. In this note the basic assumption of a constant internal rate of return of the K-L model is relaxed. As a result, the financial implications of the K-L results remain essentially unchanged, but their applicability is extended considerably, and some undesirable solution characteristics are eliminated.
