A new A$200 million securitisation-ready warehouse from National Australia Bank is setting up zipMoney for a foray into the asset-backed debt market, but not soon."An ABS securitisation is probably two years away," chief executive Larry Diamond said yesterday.zipMoney thus won't go looking for a public credit rating yet, though Diamond expressed satisfaction at the internal, but undisclosed, credit rating adopted by NAB. "You can tell I'm overall delighted with the cost of capital, an overall cost of funds of five per cent."This looks like a material saving for zipMoney. At the time of its half year results, Diamond foreshadowed this arrangement, without naming NAB. "This will approximately halve the weighted average cost of capital of our loan book," he said then.The funding line from NAB may even be "the largest fintech debt funding arrangement in Australia's recent history," the company said in its ASX announcement.zipMoney also has a $40 million, two year mezzanine facility in place, arranged through FIIG Securities.Diamond said the fintech financier also drew on $20 million in funding in junior notes from an established pool of investors.
