The disposal, ACT's second this month, confirms the group's strategy of focusing on financial software products and was welcomed by analysts.
ACT is Britain's leading financial software supplier, a position it has built up with a series of acquisitions made since 1991 with cash from the sale of its Apricot Computers business. George Soros is a new customer and clients include leading financial institutions.
The group's most recent, and biggest, acquisition was its pounds 93.5m purchase of BIS, a software subsidiary, from the New York telecoms company Nynex last July.
BIS is now one of three financial software divisions of ACT. Together these accounted for nearly four-fifths of its pounds 108m turnover in the six months to September.
Brann was a part of BIS, but ACT said direct marketing services clearly did not fit in with the group's strategy. Earlier this month it sold Cablestream, a communications network business, to Siemens for pounds 5m.
Andrew Bryant, a BZW analyst, said: 'It is good to see them disposing of peripheral businesses that were taking up management time.'
Cash from disposals has been used to settle deferred BIS payments early.Reuse content
