  We discuss issues raised by Serebrov, et al. in a recent paper regarding
systematic effects in the beam neutron lifetime experiment performed at NIST.
We show that these effects were considered in the original analyses and that
our corrections and systematic uncertainties were appropriate. We point out
some misconceptions and erroneous assumptions in the analysis of Serebrov, et
al. None of the issues raised in Serebrov, et al lead us to alter the value of
the neutron lifetime reported previously.
