The spectrum of strategic co-operations among container lines varies from loose-knitted slot charters, liner conferences, shipping alliances, joint services and consortia, through to mergers and acquisitions (M&As). However, these forms of strategic co-operations have not always been able to achieve the intended synergetic growth resulting from the integration of resources. The Resource Based View (RBV) suggests that integrating intangible resources, which are valuable, rare, inimitable and non-substitutable (VRIN), can make a significant contribution to the performance of post strategic co-operations. This research paper investigates the contribution of intangible resources to the post acquisition success six global acquisitions among container lines. The nine senior managers attached to global container lines were the main participants of this study. Five of them represented acquired container lines, four represented acquirer container lines. The paper explains their personnel experience on the processes adopts to integrate intangible resources in acquisitions. Copyright (c) 2018 The Korean Association of Shipping and Logistics, Inc.
