Dennis Leo Kozlowski (born November 16, 1946, Newark, New Jersey) is a former CEO of Tyco International, convicted of misappropriating more than $400 million of the company's funds to support a lavish lifestyle and chronic substance abuse issues. He is currently serving at least eight years and four months in prison.
Kozlowski joined Tyco in 1975, becoming CEO in 1992. With Kozlowski at the helm, Tyco massively expanded during the late 1990s. The company consistently beat Wall Street's expectations and through a series of strategic mergers and acquisitions, ushered in a new era of mega-conglomerates. Kozlowski left Tyco in 2002, amid a controversy in regard to his compensation package.
Kozlowski has been tried twice. The first attempt was a mistrial as one of the jurors - who sided with Kozlowski - later claimed that she was threatened by a member of the public. Kozlowski testified on his own behalf during the second trial, stating that his pay package was "confusing" and "almost embarrassingly big", but that he never committed a crime as the company's top executive.
