This report is concerned with the delay-dependent stability of symmetric boundary value methods (including the Extended Trapezoidal Rules of first and second kind, the Top Order Methods and the B-spline linear multistep methods) and symmetric Runge-Kutta methods (including the Gauss methods and the Lobatto IIIA, IIIB and IIIS methods) for the linear neutral delay integro-differential equation. By using the boundary locus technique, the delay-dependent stability regions of symmetric methods are analyzed and their boundary loci are discussed. It is proved that, under some conditions, the analytical stability region is contained in the numerical stability region.
