Orbit integration for three different assumed Intermediate-mass Black Hole (IMBH, defined as black holes with mass MBH in the range 100Mo 5 x 104Mo can create IMBHs, while model B assumes cluster have only to obey Mcluster > 2.5 x 103Mo to do so. In turn, given the different mass distributions within the IMBH population assuming model A or B, not more than about 15000 (A) or 16000 (B) IMBHs can be present today within the galactic disc. From the total number of IMBHs formed within star cluster in the disc, 49 % (A) or 54 % (B) have already lost their host cluster due to disruption in molecular cloud encounters. With the exception of NGC 6838, no globular cluster is expected to be destroyed via molecular cloud collisions within 10 Gyr
