  One of the attractive solutions to the information loss problem is that the
event horizon does not appear in the process of gravitational collapse and
subsequent evaporation once the spacetime singularity is regularized by some
mechanism, as pointed out by Hayward and Frolov. In this paper, we examine
whether this Hayward-Frolov scenario holds for the evaporation of a charged
black hole. The process of collapse and evaporation is modeled with the charged
Vaidya spacetime and two kinds of regularization of the central singularity are
considered. Analyzing the spacetime structure of the evaporating black hole, we
find that the appropriately regularized evaporating Reissner-Nordstr\"{o}m
"black hole" has no event and Cauchy horizons, indicating the possibility that
the Hayward-Frolov scenario may have sufficient generality as the solution to
the information loss problem. In addition, the properties of the non-singular
evaporating Reissner-Nordsto\"{o}m black hole are examined in detail.
