  In studies of heavy-ion collisions, fluctuations of conserved quantities are
considered as an important signal of the transition between the hadronic and
partonic phases of nuclear matter. In this paper, it is investigated how the
local charge conservation affects higher-order cumulants of net-charge
distributions at LHC energies. Simple expressions for the cumulants are derived
under the assumption that particle-antiparticle pairs are produced in local
processes from sources that are nearly uncorrelated in rapidity. For
calculations with these expressions, one needs to know only the second cumulant
of net-charge distribution and low-order cumulants of particle number
distribution, which are directly measurable experimentally. It is argued that
if one wishes to relate susceptibilities with cumulants of net-proton
distributions, the developed model provides a better baseline than the
conventional Skellam limit or models based on monte-carlo simulations.
