Ann: Mint Secures $6.4M in Funding, page-5

Yep. The old related party loan at 6%. Nice if you can get it. Directors know if the loan is struggling to be repaid then they can just hit the market again to have it cleared. So despite it being unsecured, there is little risk. The directors could borrow from a bank at 4% and 6% is certainly better than getting 1.5% in a bank account. Nice deal for them.
