DESCRIPTION: It has been suggested that the effects of renormalization si
 gnificantly reduce the amplitude of the inflationary spectra at scales mea
 surable in the cosmic microwave background. Via a gauge-invariant analysis
 \, we compute the renormalized scalar and tensor power spectra and follow 
 their evolution in an inflating universe that undergoes a transition to an
  FRW phase with a growing horizon. For perturbations originating from Mink
 owski vacuum fluctuations\, we show that the standard prediction for the s
 pectra on superhorizon scales is a late-time attractor\, while they are UV
  finite at all times. Our result is independent of the equation of state a
 fter inflation\, showing that the standard prediction is fully robust.\n\n
