I don't know how to post the TCL IM here but...
$7mn of the $20mn is for preference shares that will pay 4.9% in dividends + redemption after 7 years with a premium of 75%. As a "back of the envelope" calculation, it seems that "loan" is 12% per year compounded in USD assuming the 4.9% is paid annually and not accrued.
The number of preference shares being 70,120 preference shares to be allotted to Kuramo Africa has been calculated by direct reference to the Transaction Preference Share price of USD 100. The Preference Shares shall have a par value of USD 100 each, will be non-convertible and only redeemable after 7 years with a 4.9% coupon and 1.75 times redemption value.Greedy when others are fearful.
