  We obtain the mass expression of the three- and five-dimensional Lifshitz
black holes by em- ploying the recently proposed quasilocal formulation of
conserved charges, which is based on the off-shell extension of the ADT
formalism. Our result is consistent with the first law of black hole
thermodynamics and resolves the reported discrepancy between the ADT formalism
and the other conventional methods. The same mass expression of Lifshitz black
holes is obtained by using an- other quasilocal method by Padmanabhan. We also
discuss the reported discrepancy in the context of the extended first law of
black hole thermodynamics by allowing the pressure term.
