This history of Ferranti during the last six years of its long existence provides a detailed exposition of the merger with an American firm that would bring it to its knees. Although only covering six years, this builds on the previous two volumes of the Ferranti history that has outlined how the firm grew into one of the UK's leading defence electronics operations. Having survived a major liquidity crisis in 1974-75, Ferranti recovered robustly under new management, only to flounder under the same leadership as a result of a major foray into the American defence electronics industry. The case-study outlines the inherent dangers in international mergers, as well as the acute problems associated with City and corporate governance practices which resulted in decisions that undermined Ferranti fatally.
