We investigate the non-Gaussian signatures of ultra slow-roll inflation. The
bispectrum and the trispectrum are calculated with general initial conditions.
The trispectrum is of local shape, as in the case of the bispectrum. We show
that the prediction of local non-Gaussianity is robust again generalizing the
Bunch-Davies vacuum. The Suyama-Yamaguchi relation is saturated in this
scenario.Comment: 5 pages, one figur
