With the strong interest of twice over subscribed Light Trust No.1, managing director Peter Evers plans further residential mortgage backed securitisations as the inaugural $350 million offering accounts for only 15 per cent of Australian Central's residential mortgage book, which has 100 per cent fully verified loan documentation.The offering was taken up predominantly by domestic institutions, with three of the nineteen international investors having domestic operations in Australia.Evers said the credit union plans to be an annual RMBS issuer, to support its lending programs.A second offering is planned for last quarter of financial year 07/08, or the first quarter of financial year 08/09, depending on funding and capital needs. No potential RMBS size details are available."If we are more successful in growing our lending program, then we will go to the market more frequently."Evers said the Light Trust No.1 has a similar delinquency ratio compared to the overall residential lending portfolio of the credit union, and the maiden RMBS did not involve 'cherry picking' the best loans to ensure success."We pride ourselves on the quality of our lending, and we are very careful what we do take on."
