Australia's largest credit union, CUA, yesterday completed its fourth medium term note issue since 2016, raising A$225 million to put toward further expanding its loan books.Tim Moore, CUA's deputy treasurer, said the company went to market with a medium term note after a two-day series of meetings with investors in Melbourne and Sydney. CUA was seeking to raise $200 million at a guidance rate of 130 basis points over the Bank Bill Swap Rate, Moore said."We closed the order book after three hours at over $700 million from 28 investors - this is by far the biggest MTN book build that a mutual ADI has achieved in the market," he said.After considering current funding needs, CUA upsized the deal by $25 million to $225 million. The deal was tightened from original guidance of 130 bps into 125 bps over BBSW."This was the first MTN deal to tighten more than 3 bps from guidance since May of this year," Moore said."The funding raised from this MTN will help support the strong lending growth we have seen carry over into the first couple of months of FY19."Credit Union Australia Ltd is rated Baa1 (stable) and BBB (stable) by Moody's and S&P, respectively.
