The official answer is that there is no adjustment to the $3.75 figure.
Colleagues consider this immaterial, I am not sure.

But a strict reading of the PDS allows for it

I had read this :
Turners may issue further Shares from time to time before the Maturity Date of the Bonds, which may negatively affect the Share price. This may reduce the value Bondholders receive on Conversion (but subject to the minimum provided by the discounted approach). As described below, in the case of an issue of Shares to Shareholders, the terms of Conversion will be adjusted to ensure Bondholders are not adversely impacted by any dilution.


But, there is also this

If, prior to the Maturity Date, Turners issues any Shares or other instruments to its Shareholders byway of capitalisation of profits, reserves or otherwise (other than pursuant to a dividend reinvestmentplan or share purchase plan) the terms of Conversion will be adjusted to ensure Bondholders are notadversely impacted by any dilution. Turners and the Supervisor shall agree on the adjustment and ifthey are unable to agree, the Supervisor will appoint an independent adviser, approved by Turners, tomake the determination.
