Intervals of Inverse M-Matrices

If A and B are inverse M-matrices, we show that the interval determined by A and B contains only inverse M-matrices if and only if all vertices of the interval are inverse M. Limitations on strengthening such a statement are exhibited by example, and generalizations to classes of matrices defined by identically signed collections of minors are mentioned.
