Hawking's discovery that black holes radiate thermally gave rise to the long-standing ``information-loss'' paradox. The knowledge of the end-state geometry resulting from black hole evaporation is crucial in resolving this issue. In a couple of earlier works [<a href=''http://arxiv.org/abs/gr-qc/9502098''>Bose:1995pz</a>, <a href=''http://arxiv.org/abs/gr-qc/9508027''>Bose:1995bk</a>], we found that in string-inspired two-dimensional (2D) dilaton gravity (which provides a framework amenable to quantization) a natural end-state geometry is that of a semi-infinite throat, which may be regarded as a ``remnant'' of the evaporation process. Our model came to be known as the Bose-Parker-Peleg (BPP) model. Subsequently, Mikovic showed that in a manifestly unitary formulation of 2D dilaton gravity, when the spacetime metric is expanded in a power series of the quantum matter stress-tensor, one retrieves this remnant geometry in the one-loop approximation. This suggests that our solution is consistent with a unitary theory of black hole formation/ evaporation. It must be said though that a complete picture of black hole evolution requires full quantization of gravity coupled to matter, which is still an outstanding problem.
