After a recent publication of our paper (Axelsson et al., 2015), we found two incorrect/
incomplete statements in Section 2 of the paper. These statements do not have an
influence on the rest, i.e. the major part of the paper, but we feel that it is proper to publish
a corrigendum. The considered statements concern first the conditions of nonsingularity of
a nonsymmetric saddle point system, second the number of unit eigenvalues of a preconditioned
system. The correct statements are presented in this short communication.
