  Based on the recent paper hep-th/0503045, we derive a formula of calculating
conserved charges in even dimensional asymptotically {\it locally} anti-de
Sitter space-times by using the definition of Wald and Zoupas. This formula
generalizes the one proposed by Ashtekar {\it et al}. Using the new formula we
compute the masses of Taub-Bolt-AdS space-times by treating Taub-Nut-AdS
space-times as the reference solution. Our result agrees with those resulting
from "background subtraction" method or "boundary counterterm" method. We also
calculate the conserved charges of Kerr-Taub-Nut-AdS solutions in four
dimensions and higher dimensional Kerr-AdS solutions with Nut charges. The mass
of (un)wrapped brane solutions in any dimension is given.
