Motivated by the lack of power on large scales in the CMB, in this talk I will consider the existence of a non-slow roll phase preceding the inflationary epoch. I will classify such pre-inflationary phases, show which give rise to power loss and demonstrate the high level of degeneracy in pre-inflation with power loss.
