What you are suggesting is that I use the Expected Maturity Profile of Financial Assets and Liabilities, not the Contractual Liquidity Profile of Assets and Liabilities? Well my Contractual Liability Profile with certain reinvestment assumptions should be somewhere near the 'Expected Liability Profile', but let's see.
From note 38, HNZ Expected Cash Reinvested (12 month forward view) = $4.522m + $342.029m + $231.600m = $805.229
Compare that with the figures I calculated of $1,045.494 ( 80% reinvestment rate ) or $600.384m ( 60% reinvestment rate ). Since the actual figure is in the middle of my guesses, one might conclude that the actual reinvestment rate of debentures that are due within one year is somewhere near 70% (likely closer to 75%) . Of course that is simplifying a lot of data. But is nevertheless a useful insight of the overall debenture reinvestment rate at Heartland.
