In a series of papers, B.E. Rhoades and M. Yildirim previously investigated the spectra and fine spectra for factorable matrices, considered as bounded operators over various sequence spaces. In the present paper approximation point spectrum, defect spectrum and compression spectrum of factorable matrices are investigated.
