“…There have been different approaches investigating motives (Arnold & Parker, 2009;Berkovitch & Narayanan, 1993;Nguyen et al, 2012;Trautwein, 1990), synergies (Chatterjee, 2007;Damodaran, 2005;Ficery et al, 2007;Garzella & Fiorentino, 2014;Goold & Campbell, 1998;Kode et al, 2003), PMI (Adams & Neely, 2000;Angwin & Meadows, 2015;Datta, 1991;Joseph, 2014;Weber et al, 2012), evaluation methods (Ahammad & Glaister, 2013;Calandro et al, 2007;Kode et al, 2003), etc.. Referring to timing concepts, only speed has been investigated in more detail, stating that there is a limited time frame to realise synergies after closing (Angwin, 2004;Bert et al, 2003).…”
