Its likely they have paid a portion of the audit fees, most likely around 80% of the fee, this is what would be showing up in the quarterly. Standard practice for audit/accounting firms would be to progressively bill throughout the year on engagements like these. Using last years audit fee as a guide would also be misleading as more than likely this years (FY18) will be higher due to situation regarding uncertainty for CTL to operate as a going concern ie issues around the notes and capital raising.
