1 | Consists of 164,939,999 redeemable preference shares at par value for US$164,939,999.
The following table shows a reconciliation from the fair value at acquisition to the fair value of the redeemable preference shares at the end of the year (level 3 financial instrument):
Fair value at acquisition |  |  | 129,9 |
Net change in fair value (recognised in OCI) |  |  | 3,0 |
Fair value at end of the year |  |  | 132,9 |
The fair value is based on the expected cash flows of the Asanko Gold Mine based on the life-of-mine model. The following key inputs were used in the valuation of the fair value:
Par value of the preference shares |  | US$ | 165.0 million |
Market-related interest rate |  |  | 7,85 | %
Expected redemption period |  |  | 5 years |
Any reasonable change in the timing of the cash flows or market-related discount rate could materially change the fair value of the redeemable preference shares (refer note 38 for sensitivity analysis performed). Refer to note 15 and 16.1 (b) for further details.
2 | Consists of 10.0 million common share purchase warrants of Maverix. Refer note 16.1 (c) for further details.
