Where drawn facilities mature within one year and the Group has an unconditional right to refinance the loans through undrawn facilities with the same lenders with maturity dates of greater than one year from the end of the reporting period, the loan is considered non-current.
All of the Group's borrowings are unsecured. The Group borrows under a negative pledge arrangement with its bank loan providers, which with limited exceptions does not permit the Group to grant any security interest over its assets. The negative pledge deed requires the Group to maintain certain levels of shareholders' funds and operate within defined performance and debt gearing ratios. The banking arrangements may also create restrictions over the sale or disposal of certain assets unless the bank loans are repaid or renegotiated, specifically:
Throughout the period the Group has complied with all debt covenant requirements as imposed by lenders (see above for requirements).
- Facilities (i), (ii), (v), (vi) and (vii) require a continuation of the existing business operations. There are no costs to cancel the facilities.

- Facility (vii) must be repaid if Snowtown South Wind Farm Pty Ltd is sold.
