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.
