1987 was a key year for Hawley. In the early part of the year, it bought Crime Control Inc. based in Indianapolis, for $50 million, placing the company in fourth place in the U.S. security market. Later in the year it bought ADT Security Services, the largest electronic security company in the United States. This purchase transformed Hawley into the leading security services business in the United States, and resulted in the majority of its revenues coming from the North American market. As a result of the acquisition, Bermuda-registered Hawley changed its name to ADT Inc. and decided to refocus its business around security services. At the end of 1987, the company sold its North American-based facility services business to Denmark's ISS A/S.
In 1987, Ashcroft bought out the existing shareholders of Wickins BCA via Hawley Goodall. Based at Blackbushe Airport to allow Wickins access to his treasured aviation division, which flew both Jet Ranger helicopters and Beechcraft King Air turbo prop aircraft, Ashcroft, who has a disliking for such flippant expenditure, immediately sold off the aircraft. Wickins joined the board of Hawley Goodall, remaining there until the Tyco takeover, but retired from BCA in 1990. In 1995, to allow for the Tyco transaction, the group decided to divest itself of BCA. The residual North American arm was sold to trade buyers, while the European arm was sold to a consortium of some 40 private investors, including Ashcroft via his Belize-based investment company. In September 2006, BCA was bought by the UK-based investment banking arm of private bank Samuel Montagu & Co., a division of HSBC, personally netting Ashcroft over £200 million.
In 1987, BHI led the formation of Belize Bank Holdings (BBH), which took control of Belize Bank from the Royal Bank of Canada. Belize Bank has become the country's largest financial institution, controlling some 50 percent of the market. BBH developed local and international interests in facilities services, finance and telecommunications. Belize Bank itself formerly held a majority stake in Belize Telemedia Limited (BTL), until it was nationalised by the Government of Belize.
