Innovia Films said yesterday that it would buy the Reserve Bank of Australia's 50 per cent share of Securency International. The company makes polymer substrate for banknotes. Securency has been dogged by controversy over the payment of bribes. Currently, a number of Securency executives are facing charges that they bribed foreign officials. The RBA said it would receive initial payments of approximately A$65 million for its shares. It said this exceeds the company's book value of $54 million. Additional payments may be made to the RBA over following years should Securency exceed earnings benchmarks, the RBA said.Both Innovia and the RBA said the bank would use the Securency product in manufacturing the planned replacement of Australia's banknotes.
