Per the article, they are seeking to tap the institutional debt market
. This is a good think in my view (and in my experience as a former banker and someone who now works in the institutional private debt space) as the banks these days are not in the business of long term debt facilities.
Whereas placing the debt as a bond style instrument allows for much greater loan tenor at competitive interest rates and with covenants that are often not as onerous as the banks would demand - as the article highlighted. Add that Infigen's portfolio is viewed as infrastructure assets (flavour of the month for institutions), I think it al bodes well for an outcome which will provide much enhanced balance sheet flexibility. The fact that the market "liked" the news is also testament to this.
