Ann: Chairman Provides A$1m Convertible Loan Facility, page-5

It looks like YPB failed to raise funds (not surprising in this market) and JH has lent the company his own money to keep it afloat.

This is a bit of a risk as YPB may also struggle to raise capital in the future. I guess JH is willing to take the risk because if YPB can't raise capital later on he becomes the sole creditor. In the event of VA could simply swap his debt for full ownership of the company. This could potentially allow him to release the only value within the company, which is its tens of millions of dollars worth of carried forward losses. YPB would become an attractive reverse takeover target as it would allow a profitable company to list under the YPB structure cheaply and inherit the tax losses, which it could offset against its future profits.
