Allco Finance Group chief executive David Clarke told shareholders at the company's annual general meeting yesterday that he had called for a strategic review of the group wholesale lending business, Mobius.Mobius has been in the news for all the wrong reasons this year. In August Standard & Poor's reported that the company, which provides a white label service to mortgage managers, had the worst-performing portfolio of non-conforming mortgages, with 23 per cent of loans 30 days past due.Soon after, it was revealed that one of the mortgage managers Mobius dealt with was broke and another was in court over mis-selling of loans.The company announced that it was taking steps to tighten its model, which it acknowledged had been very loose. A couple of mortgage managers were creating their own products for Mobius to fund.Late in August Mobius dropped a no doc loan from its product range.Mobius has other problems. It is sub scale, with less than $2 billion of loans on its books and it faces difficulty securing funding at a reasonable price.Clarke did not elaborate on the direction of the review.
