Thorn Group has given up on its unsuccessful ventures into small consumer loans and receivables management and now it must turn around its trade and debtor finance division, a business it got into in 2014 when it acquired Cash Resources Australia.The trade and debtor finance division, an invoice discounting business, suffered a 20.2 per cent fall in revenue in the six months to September, compared with the previous corresponding period, and a 28.2 per cent fall in EBIT to A$2 million.When Thorn bought CRA in 2014 it paid $42.8 million for a business with $40 million of receivables. Receivables were down to $37 million in the September half.Thorn Group managing director James Marshall said Thorn was sticking with the business, investing in a new platform that would improve transaction times and introduce more automation.The business has been re-branded and it is targeting higher quality clients (which will mean lower margins). Thorn is "transitioning out" a number of the old CRA clients.Marshall said the work was beginning to show some results, with sales through brokers picking up.Overall, Thorn Group reported a net profit of $15.2 million for the six months to September - down 1.3 per cent from the previous corresponding period.Profit from continuing operations rose 6.1 per cent.Revenue from continuing operations was up 2.8 per cent to $156.8 million. The company did not report revenue on a statutory basis -  a breach of ASIC guidance on financial reporting (RG 230).If the company had reported all its revenue for the period it would have shown revenue growth of 1.9 per cent to $163.9 million.The strongest part of the business was Thorn Equipment Finance, which has a 52.5 per cent increase in revenue, a 74.8 per cent increase in receivables and a 48.3 per cent increase in EBIT to $6.6 million.The Radio Rentals consumer leasing business had a mixed result, with receivables up 29 per cent, revenue up 2.3 per cent but EBIT down 0.4 per cent to $25 million.Marshall said increased customer due diligence requirements had increased transaction time and also resulted in lower conversion rates from leads.He said Thorn was building new stores, refurbishing existing ones and beefing up its marketing to build Radio Rentals' market share.In September Thorn completed the sale of its receivables management business NCML, reporting a small loss on the sale.Last year it announced that it would close its small consumer loan business and put the book in runoff.
