  We are conducting a systematic study of highly-ionised outflows in AGN using
archival Suzaku data. To date we have analysed 59 observations of 45 AGN using
a combined energy-intensity contour plot and Montecarlo method. We find that
~36% (16/45) of sources analysed so far show largely unambigous signatures
(i.e., Montecarlo proabilities of >95%) of highly-ionised, high-velocity
absorption troughs in their X-ray spectra. From XSTAR fitting we find that,
overall, the properties of the absorbers are very similar to those found
recently by Tombesi et al. (2010,2011) with XMM-Newton for the same phenomenon.
