management team as executive chairman; and spearheaded KN's future expansion, particularly its European and the Far Eastern operations. In 1981, Alfred Kühne died; and in July the same year, due to the losses sustained by the Kühne family in attempting to expand its shipping fleet, a 50% stake in KN was sold to the British conglomerate Lonrho Plc for 90 million DM. Following the purchase, Klaus-Michael Kühne and Lonrho's head, Roland "Tiny" Rowland acted as joint chief executives of the combined organisation. KN further expanded with its acquisition of freight companies: Domenichelli SpA (Italy), Van Vliet BV (Netherlands), Hollis Transport Group Ltd. (UK), Transportes Tres (Spain), and other acquisitions in Denmark, Norway, and Sweden. Further expansion: 1990s - present The 1990 German reunification was an important event for many German companies, including KN; and provided them the necessary impetus to expand further. After the reunification, KN integrated its network in the former German Democratic Republic, and consolidated its operations. In 1992, it bought back Lonrho plc's 50% stake in the company; and went public in May 1994. It was listed on the Zurich and Frankfurt exchanges, which provided a platform for further exchange-based acquisitions. The same year, KN established a Russian subsidiary; and pushed ahead into Norway, Sweden, and Denmark. In the mid 1990s, strategic focus given to expand the lucrative logistics-related contracts / operations paid off - one being with DuPont in which KN would operate the chemical giant's leveraged distribution activities in Europe, the Middle East, and Africa. In July 1999, Kühne handed over the post of CEO to Klaus Herms, and continued as the executive chairman and president of the board. In the early 2000s, KN got a foothold in the Asia Pacific contract logistics market, when it forged a strategic alliance with Singapore-based SembCorp Logistics. In 2001, it acquired USCO Logistics Inc. - a warehouse-based logistics service provider based in Hamden, Connecticut, for US$300 million. KN and SembCorp chose to follow different strategic paths in 2004, and ended their strategic partnership. In October 2007, the board of KN appointed Reinhard Lange as the successor to CEO Klaus Herms, effective June 2009 to ensure a smooth handover. The succession plan was similar to the SAP's 2007 CEO transition plan from Henning Kagermann to Léo Apotheker, which received praise in the media. In 2012, Kuehne + Nagel acquired the business contracts of Canada's Perishables International Transportation (PIT) to
