Note 5 - Blanket Zimbabwe Indigenization Transaction

Disclosure of the Blanket Zimbabwe indigenisation transaction [text block]

Blanket Zimbabwe Indigenisation Transaction

February 20, 2012

the Group announced it had signed a Memorandum of Understanding (“MoU”) with the Minister of Youth, Development, Indigenisation and Empowerment of the Government of Zimbabwe pursuant to which the Group agreed that indigenous Zimbabweans would acquire an effective

51%

ownership interest in the Zimbabwean company owning the Blanket Mine (also referred to herein as “Blanket” or “Blanket Mine” as the context requires) for a paid transactional value of

$30.09

million. Pursuant to the above, members of the Group entered into agreements with each indigenous shareholder to transfer

51%

of the Group's ownership interest in Blanket Mine whereby it:

sold a

16%

interest to the National Indigenisation and Economic Empowerment Fund (“NIEEF”) for

$11.74

million;

sold a

15%

interest to Fremiro Investments (Private) Limited (“Fremiro”), which is owned by indigenous Zimbabweans, for

$11.01

million;

sold a

10%

interest to Blanket Employee Trust Services (Private) Limited (“BETS”) for the benefit of present and future managers and employees for

$7.34

million. The shares in BETS are held by the Blanket Mine Employee Trust (“Employee Trust”) with Blanket Mine's employees holding participation units in the Employee Trust; and

donated a

10%

ownership interest to the Gwanda Community Share Ownership Trust (“Community Trust”). In addition, Blanket Mine paid a non-refundable donation of

million to the Community Trust.

The Group facilitated the vendor funding of these transactions which is repaid by way of dividends from Blanket Mine.

80%

of dividends declared by Blanket Mine are used to repay such loans and the remaining

20%

unconditionally accrues to the respective indigenous shareholders. Following a modification to the interest rate on

June 23, 2017,

outstanding balances on these facilitation loans attract interest at a rate of the lower of a fixed

7.25%

per annum payable quarterly or

80%

of the Blanket Mine dividend in the quarter. The timing of the repayment of the loans depends on the future financial performance of Blanket Mine and the extent of future dividends declared by Blanket Mine. The facilitation loans relating to the Group were transferred as dividends in specie intra Group and now the loans and most of the interest thereon is payable to the Company.

Accounting treatment

The directors of Caledonia Holdings Zimbabwe (Private) Limited (“CHZ”), a wholly owned subsidiary of the Company, performed a re-assessment, using the requirements of IFRS

10:

Consolidated Financial Statements (IFRS

), and concluded that CHZ should continue to consolidate Blanket Mine after the indigenisation and accordingly the subscription agreements with the indigenous shareholders have been accounted for as a transaction with non-controlling interests and as a share based payment transaction.

The subscription agreements, concluded on

February 20, 2012,

were accounted for as follows:

Non-controlling interests (“NCI”) were recognised on the portion of shareholding upon which dividends declared by Blanket Mine will accrue unconditionally to equity holders as follows:

(a)

20%

of the

16%

shareholding of NIEEF;

(b)

20%

of the

15%

shareholding of Fremiro; and

(c)

100%

of the

10%

shareholding of the Community Trust.

	·	This effectively means that NCI was recognised at 16.2% of the net assets of Blanket Mine, until the completion of the transaction with Fremiro whereby the NCI reduced to 13.2% (see below).

	·	The remaining 80% of the shareholding of NIEEF and Fremiro is recognised as non-controlling interests to the extent that their attributable share of the net asset value of Blanket Mine exceeds the balance on the facilitation loans including interest. At June 30, 2020 the attributable net asset value did not exceed the balance on the respective loan accounts and thus no additional NCI was recognised.

	·	The transaction with BETS is accounted for in accordance with IAS 19 Employee Benefits (profit sharing arrangement) as the ownership of the shares does not ultimately pass to the employees. The employees are entitled to participate in 20% of the dividends accruing to the 10% shareholding in Blanket Mine if they are employed at the date of such distribution. To the extent that 80% of the attributable dividends exceeds the balance on the BETS facilitation loan they will accrue to the employees at the date of such declaration.

	·	The Employee Trust and BETS are entities effectively controlled and consolidated by Blanket Mine. Accordingly, the shares held by BETS are effectively treated as treasury shares in Blanket Mine and no NCI is recognised.

Fremiro purchase agreement

November 5, 2018

the Company and Fremiro entered into a sale agreement for Caledonia to purchase Fremiro's

15%

shareholding in Blanket Mine. On

January 21, 2020

all substantive conditions to the transaction were satisfied and the Company issued

727,266

shares to Fremiro for the cancellation of their facilitation loan and purchase of Fremiro's

15%

shareholding in Blanket Mine. The transaction was accounted for as a repurchase of a previously vested equity instrument. As a result, the Fremiro share of the NCI of

$3,600

was derecognised, shares were issued at fair value, the share based payment reserve was reduced by

$2,247

and the Company's shareholding in Blanket Mine increased to

64%

on the effective date.

# Facilitation loans are accounted for as equity instruments and are accordingly

recognised as loans receivable.

Advance dividend loans and balances

million payment on or before

September 30, 2012;

million payment on or before

February 28, 2013;

and

million payment on or before

April 30, 2013.

These advance payments were debited to a loan account bearing interest at a rate at the lower of a fixed

7.25%

per annum, payable quarterly or the Blanket Mine dividend in the quarter to the advanced dividend loan holder. The loan is repayable by way of set-off of future dividends on the Blanket Mine shares owned by the Community Trust. Advances made to NIEEF as an advanced dividend loan before

2013

have been settled through Blanket Mine dividend repayments in

2014.

The advance dividend payments were recognised as distributions to shareholders and they are classified as equity instruments. The loans arising are

not

recognised as loans receivable, because repayment is by way of uncertain future dividends.

Amendments to advanced dividend loan agreements

Advance dividend loan modification - Community Trust

February 27, 2020,

the Group, Blanket Mine and the indigenous shareholders of Blanket Mine reached agreement to change the repayment terms of the advance dividend loan to the Community Trust. The amendment allowed that

20%

of the Community Trust share of the Blanket dividend accrue on declaration of the dividend and that the remaining

80%

be applied to the advance dividend loan from

February 27, 2020.

The modification was

not

considered beneficial to the indigenous shareholders.

The movement in the advance dividend loan to the Community Trust is reconciled as follows:

Government grant – Gold sale export incentive

The Reserve Bank of Zimbabwe (“RBZ”)

first

announced an export credit incentive (“ECI”) on the gold proceeds received for all large-scale gold mine producers during

2016.

The ECI is calculated as a percentage of the gold proceeds less the charges of Fidelity Printers and Refiners Limited (“Fidelity”). The below table indicates when the ECI was applicable and the percentages applied, as announced by government:

ECI applicable periods	Percentage
May 1, 2016 – January 1, 2018	3.5%
January 1, 2018 – February 1, 2018	2.5%
February 1, 2018 – February 20, 2019	10%
March 10, 2020 – June 26, 2020	25%

All incentives granted by the Zimbabwean government were included in other income when determined receivable and receipts were received in Blanket Mine's RTGS$ account. ECI fell away after

June 26, 2020.

Government grant – Gold support price

From

March 6, 2019

it became apparent that Blanket Mine's sales proceeds received from Fidelity were calculated at a gross price of

$44,000

per kilogram (

$1,368.58

per ounce), which exceeded the prevailing London Bullion Market Association (“LBMA”) price. On

May 12, 2019,

the Company received confirmation from Fidelity of this windfall receipt, called the “gold support price”, which has been implemented to incentivise gold producers to increase gold production.

gold support price was received as the LBMA gold price for the last

months was over and above

$1,368.58

(a) Restricted Share Units and Performance Units

Certain key management members were granted Restricted Share Units (“RSUs”) and Performance Units (”PUs”) pursuant to provisions of the

2015

Omnibus Equity Incentive Compensation Plan. All RSUs and PUs were granted and approved by the Compensation Committee of the Board of Directors.

RSUs vest

three

years after grant date given that the service condition of the relevant employees have been fulfilled. The value of the vested RSUs is the number of RSUs vested multiplied by the fair market value of the Company's shares, as specified by the plan, on date of settlement.

PUs have a performance condition based on gold production and a performance period of

three

years. The number of PUs that vest will be the PUs granted multiplied by the performance multiplier, which will reflect the actual performance in terms of the performance conditions compared to expectations on the date of the award.

RSUs and PUs allow for settlement of the vesting date value in cash or shares issuable at fair market value or a combination of both at the discretion of the unit holder.

Net foreign exchange gain

October 1, 2018

the RBZ issued a directive to Zimbabwean banks to separate foreign currency from RTGS$ in the accounts held by their clients and pegged the RTGS$ at

1:1

to the US Dollar. On

February 20, 2019

the RBZ issued a further monetary policy statement, which allowed inter-bank trading between RTGS$ and foreign currency. The interbank rate was introduced at

2.5

RTGS$ to

US Dollar and traded at

57.3582

RTGS$ to

US Dollar as at

June 30, 2020 (

December 2019:

16.77

RTG$). On

June 24, 2019

the Government issued S.I.

142

which stated, “

Zimbabwe dollar (RTGS$) to be the sole currency for legal tender purposes for any transactions in Zimbabwe”.

Throughout these announcements and to the date of issue of these financial statements the US dollar has remained the primary currency in which the Group's Zimbabwean entities operate and the functional currency of these entities.

Previously there was uncertainty as to what currency would be used to settle amounts owed to the Zimbabwe Government. The announcement of S.I.

142

clarified the Zimbabwean Government's intentions that these liabilities were always denominated in RTGS$ and that RTGS$ would be the currency in which they would be settled. The devaluation of the deferred tax and electricity liabilities contributed the largest portion of the foreign exchange gain set out below.

The table below illustrates the effect the weakening of the RTGS$ and other non-RTGS$ currencies had, against the US Dollar, on the statement of profit or loss and other comprehensive income.
