Rubin transformed the company, renamed Pentland Group in 1973, into the UK's largest Sports apparel and footwear company, owning a number of brands including Berghaus, Brasher, Ellesse, Hunter, Mitre and Speedo, amongst others. It is also the majority owner of JD Sports Fashion plc. Its success largely came from an investment in August 1981, acquiring 55% of Reebok for US$77,500. By 1983/84, Reebok accounted for 70% of Pentland's turnover. Pentland's shares rose from 55p at the start of 1984 to GB£3 at the end of the year and up to GB£10 in 1985, while profits rose from GB£1 million in 1983 to GB£12.9 million in 1985. Rubin then sold off Pentland's stake in Reebok for US$770m in 1991.
