National Bank of Abu Dhabi (NBAD), which debuted as a Kangaroo issuer on February 28, says engagement with domestic investors is key to the diversification it hopes to achieve by becoming a repeat borrower in the Australian market. The bank had been looking at the Kangaroo market for two years prior to issuing its first deal, waiting until it was comfortable it would achieve at least 50 per cent take up from local buyers in its debut.
