The knowledge of the cut-off energy ($E_{cut}$) of the primary X-ray continuum in an AGN is very important as it carries information on the physical characteristics of the hot X-ray emitting corona. We present here the results of our investigation on the spectral properties of a sample of 10 nearby AGN (0.005 $<$ $z$ $<$ 0.037) observed with the {\\it Nuclear Spectroscopic Telescope Array (NuSTAR)} .
