Notes to the Group annual financial statements | Note 3.1

Credit risk, or the risk of financial loss to the Group due to customers or counterparties not meeting their contractual obligations, is managed through the application of credit approvals, limits and monitoring procedures. The Group is exposed to credit risk on financial assets mainly in respect of those assets detailed in the table below. The carrying amounts of financial assets represent the maximum credit exposure. This exposure is considered, without taking into account any collateral and financial guarantees, to be as follows:

The Group's maximum credit risk exposure is the carrying amount of the above financial assets included on the statement of financial position.

The table below discloses the credit quality of the financial assets (excluding trade receivables) of the Group for which external credit ratings are available. External credit ratings were based on the latest Moody's default ratings. The counterparties were categorised as follows:

Group 1: Financial institutions with a Moody's long-term debt issuer rating of Ba2 or better, or cash on hand. Insignificant ECL;

Group 2: Fully performing, with a Moody's rating of Ba2 or better;

Group 3: Fully performing, with a Moody's rating of between Ba3 and Caa2; and

Group 4: Counterparties who are considered to be in default and those that have a Moody's rating of Caa3 or lower.

The groupings above, as referenced throughout this note, are generally aligned to the staging requirements of IFRS 9 as follows:

• Group 1 financial assets are typically Stage 1.
• Group 2 financial assets are typically Stage 1, with minor Stage 2 balances.
• Group 3 financial assets are typically Stage 2, with minor Stage 1 balances.
• Group 4 financial assets are typically Stage 3.

The table below discloses the credit quality of the financial assets (excluding trade receivables) of the Group for which no external credit ratings are available. Equivalent credit ratings were based on the latest Moody's default ratings. These ratings include forward looking adjustments for all relevant economic factors, including the impact of Covid-19 for the prior period. Management defines default as when counterparties miss payments and future payments are either suspended or unlikely. Management writes off debtors where they have actively pursued the debt and there is no indication of recovery.

The counterparties were categorised as follows:

Group 1: Fully performing counterparties with no external credit ratings. ECL range up to 7.63% (2021: Up to 6.43%);

Group 2: Fully performing counterparties, with a credit rating equivalent to a Moody's rating of B1 or better. ECL range of 7.63% to 9.26% (2021: 6.43% to 7.57%);

Group 3: Fully performing counterparties, with a credit rating equivalent to a Moody's rating of between B2 and Caa2. ECL range of 9.26% to 54.0% (2021: 7.57% to 53.4%); and

Group 4: Counterparties who are considered to be in default and have an equivalent Moody's rating of Ca or lower. ECL of 54.0% to 100% (2021: 53.4% to 100%).

Impact of Covid-19 and other current economic events

The impact of Covid-19 on the ECLs recognised in the current and prior financial years has been considered across all financial assets exposed to counterparty credit risk. Covid-19 resulted in the Group initially accounting for general increases in allowances for ECLs, with recoveries in the current and prior financial years due to a more stable economic outlook, as well as efforts to clean up long outstanding receivables.

ECLs were determined by the Group based on an unbiased, probability weighted amount that is determined by evaluating a range of possible outcomes and, where relevant, reflecting the time value of money. In accordance with the requirements of IFRS 9, ECL allowances are required to be measured in a way that incorporates information available at the reporting date about past events, current conditions and forecasts of future economic conditions. Each of these were used in calculating the ECL on the in-scope financial assets of the Group. Moody's Analytics is used to incorporate forward looking information in the determination of ECL. Moody's consider the effect of Covid-19 to be embedded in the underlying actual results of entities, and as a result reflected in the probability of default (PD) assumption of underlying ECL methodologies. As such, no significant Covid-19 overlays or other adjustments, other than the macro-economic forecasts have been included in the current financial year.

Moody's Analytics produces a set of macro-economic forecasts for South Africa that considers the historical accuracy of various forecasters to identify reliable sources. These are incorporated into their GCorr macro-economic forecast set. Based on research conducted by Moody's Analytics, it recommends the use of its Baseline, Stronger Near-Term Rebound (S1), and Moderate Recession (S3) forecast sets weighted 40%, 30% and 30% (2021: 40%: 30%: 30%) respectively for a forward looking adjustment for the purposes of IFRS 9. It considers both public and private South African company defaults in this research. The methodology considers the industry of the asset and the related volatility in comparison to the average volatility in the South African economy.

The advent of Covid-19 had a fundamental impact on the economy in general with an exaggerated impact on credit risk, however in the subsequent financial years, these impacts have normalised. Moody's Analytics continually update their forecasts to reflect these changing risk factors by taking into account the possible spread of the epidemic through the country, the economic impact of the epidemic including measures taken to prevent its spread and measures taken by government to ameliorate the economic impact. Moody's recommend to continue applying the Baseline, S1 and S3 GCorr scenarios weighted 40%, 30% and 30% (these scenarios have been adjusted to reflect the change in risk). We calculated the 2022 financial year ECL scenarios based on a GCorr weighting of 40%, 30% and 30%, consistent with the prior year.

Expected credit losses

The Group has the following financial assets subject to the expected credit loss model:

• trade and other receivables;
• cash and cash equivalents;
• loans to associates and joint ventures;
• loans receivable; and
• advances to customers.

The Group applies the simplified approach using a provision matrix (refer below) to determine the ECL for trade and other receivables, and advances to customers. This results in calculating lifetime ECLs for these classes of financial instruments.

Loans to associates and joint ventures, as well as loans receivable, are amounts receivable to which the Group has applied the general impairment model. The Group has considered the financial performance, external debt and future cash flows of the related parties and, based on these, determined the credit risk relating to these receivables.

The Group tracks significant increases in credit risk using information available to the Group regarding the counterparty credit risk. Furthermore, this is supplemented by taking into account the performance of the counterparty to the financial asset in question, as well as data from Moody's Analytics where applicable. Significant increases in credit risk can be evaluated with reference to movements in the balances between the grouping categories used throughout this note.

ECLs for receivables, other than trade receivables and advances to customers, have been determined using the general approach in IFRS 9. Under the general approach, an entity calculates ECLs for loans and receivables at initial recognition by considering the consequences and probabilities of possible defaults only for the next 12 months, rather than the life of the asset. It continues to apply this method until a significant increase in credit risk has occurred, at which point the loss allowance is measured based on lifetime ECLs.

The Group has applied the requirements of the general approach of IFRS 9 for counterparties where no external credit ratings are available, by way of the use of a management determined credit risk rating model. The management of the Group performs a rigorous internal rating assessment process of all external counterparty credit risk exposures and rate these exposures grouping them into the below four groups which are then aligned to equivalent Moody's sourced default ratings.

Management defines default as when counterparties miss payments and future payments are either suspended or unlikely.

Group 1: Fully performing counterparties with no external credit ratings. ECL range up to 7.63% (2021: Up to 6.43%).

Group 2: Fully performing counterparties with a credit rating equivalent to a Moody's rating of B1 or better. ECL range of 7.63% to 9.26% (2021: 6.43% to 7.57%).

Group 3: Fully performing counterparties with a credit rating equivalent to a Moody's rating of between B2 and Caa2. ECL range of 9.26% to 54.0% (2021: 7.57% to 53.4%).

Group 4: Counterparties who are considered to be in default and have an equivalent Moody's rating of Ca or lower. ECL of 54.0% to 100% (2021: 53.4% to 100%).

(i) Trade and other receivables

The Group has a diversified customer base and policies are in place to ensure sales are made to customers with an appropriate credit history and payment history. All of the Group's revenues are generated in South Africa. Individual credit limits are set for each customer and the utilisation of these credit limits is monitored regularly. Customers cannot exceed their set credit limit without specific Senior Management approval. Such approval is assessed and granted on a case by case basis. Management regularly reviews the receivables age analysis and follows up on long-outstanding receivables. Allowances for impairment are raised in accordance with Group policy, which aligns to the requirements of IFRS 9. The Group's customer base has been aggregated into groupings that represent, to a large degree, how the Group manages its receivables and also illustrates the spread of credit risk. Within these aggregated groupings, the Group's exposure to credit risk is made up of banks (and other financial institutions), major retailers, independent and informal retail customers, petroleum forecourts, municipalities, private utilities and cellular networks. The balance of the customer base is widely dispersed.

Provision matrix (including advances to customers)

ECLs are calculated by applying a loss ratio to the aged balance of receivables at each reporting date. The loss ratio is calculated according to the ageing/payment profile of sales by applying historic/proxy write-offs to the payment profile of the sales population. In instances where there was no evidence of historical write-offs, management used a proxy write-off for similar receivables obtained from external credit rating agencies. Receivable balances have been grouped so that the ECL calculation is performed on groups of receivables with similar risk characteristics and ability to pay. Exposures are mainly segmented by customer type, i.e. banks (and other financial institutions), major retailers, independent and informal retail customers, petroleum forecourts, municipalities, private utilities and cellular networks. This is done to allow for risk differentiation. Similarly, the sales population selected to determine the ageing/payment profile of the sales is representative of the entire population and in line with future payment expectations. The historic loss ratio is then adjusted for forward looking information to determine the ECL for the portfolio of receivables at the reporting date to the extent that there is a strong correlation between the forward looking information and the ECL.

In prior years, in most instances, no material adjustments were required to accommodate forward looking information, as the majority of receivables were settled within a relatively short period (under 60 days on average). Due to the uncertainty relating to the impact of Covid-19, however, forward looking adjustments were made.

In the current year, Moody's consider the effect of Covid-19 to be embedded in the underlying actual results of entities, and as a result reflected in the probability of default (PD) assumption of underlying ECL methodologies. As such, no significant Covid-19 overlays or other adjustments, other than the macro-economic forecasts have been included. Refer to 'Impact of Covid-19 and other current economic events' paragraph above.

The Group used 60 to 72 months' sales data to determine the payment profile of the sales. Where the Group has information about actual historical write-offs, actual write-offs have been used to determine a historic loss ratio. Alternatively, management has used a proxy write-off, based on management's best estimate including information obtained from an external ratings agency (Moody's). The Group has considered quantitative forward looking information such as the core inflation rate. Qualitative assessments have also been performed, of which the impact was found to be immaterial, except for the impact of Covid-19, as noted above.

Management considers trade receivables aged in excess of 90 days past due (where the excessive ageing is not caused by administrative delays that are within the control of the Group), and those handed over to the Group's attorneys for legal collection processes, to be in default and accordingly increases the allowance for impairment raised on these receivables. This policy is applied to all receivables, other than receivables for starter packs, municipalities, private utilities or specific circumstances where management has rebutted the presumption that a customer is in default when 90 days past due as a result of the inherent nature of the product/transaction being undertaken which follows a business cycle in excess thereof. Receivables for starter packs are considered to be in default where no income has been earned from activation or ongoing revenue in the last three months and the receivable has aged in excess of the anticipated repayment cycle. Receivables from municipalities and private utilities are considered to be in default where the net exposure to the counterparty after deduction of the collateral held has aged in excess of 12 months, or where handed over to the Group's attorneys for legal collection purposes.

Trade receivables are written off when there is no reasonable expectation of recovery. This is assessed individually by each operation and includes, for example, where the trade receivables have been handed over for collection and remain outstanding or the debtor has entered bankruptcy. Other receivables and other financial assets are individually assessed by management based on each situation's unique facts and circumstances and are written off when management believes that there is no reasonable expectation of recovery.

The loss allowance as at 31 May 2022 for trade receivables and other receivables to which the provision matrix has been applied is determined as follows:

Ageing and impairment analysis

(ii) Cash and cash equivalents

The Group places cash and cash equivalents with major banking groups and quality institutions that have high credit ratings. The Group has the majority of its credit risk with Investec Bank Limited in line with its treasury function. Investec Bank Limited has a credit rating of Ba2 based on the latest Moody's local currency long-term issuer default ratings.

(iii) Loans to associates and joint ventures

The Group has provided loans to associates and joint ventures of the Group to satisfy operational and other requirements. These associates and joint ventures are located in South Africa. The Group manages credit risk on this portfolio of loans by following strict protocols for the approval thereof, and where possible obtaining appropriate security and other collateral. Management regularly reviews these loans and uses an internal ratings-based system to track credit risk thereon. Allowances for impairment are raised in accordance with the general model in IFRS 9 to which Group policy has been aligned. Refer to note 2.1.

The loss allowance as at 31 May 2022 for loans to associates and joint ventures is determined as follows:

(iv) Loans receivable

The Group has provided loans to third parties who are seen as product distributors, in order to expand its distribution channels. These loans have been extended on various terms depending on management's assessment of the business rationale for the provision thereof. The Group manages credit risk by following strict protocols for the approval and monitoring of these loans, and where possible, obtaining appropriate security and other collateral. Management regularly reviews these loans and uses an internal ratings-based system to track credit risk thereon. Allowances for impairment are raised in accordance with the general model in IFRS 9 to which Group policy has been aligned.

The loss allowance as at 31 May 2022 for loans receivable is determined as follows:

(v) Advances to customers

Advances to customers represent the activities of the Group's subsidiary, Comm Equipment Company Proprietary Limited (CEC), which provides financing for cellular handsets and cellular subscription services. This customer base is widely dispersed throughout South Africa and no significant concentrations of credit risk have been noted.

The business model of these financing arrangements changed part-way through the prior year, and exposes the Group to the credit risk of the population of the underlying subscribers who are all customers of Cell C Proprietary Limited and other business partners of CEC.

The current financial year is the first full reporting period incorporating the results of the new business model, which has allowed management to gather additional data and perform refinements to the provision matrix as detailed below. This additional data and the resulting refinements have culminated in an increase in the impairment raised on the Handset financing and subscription income sharing receivables as detailed in the table below.

Management has put in place credit risk policies as well as stringent customer acceptance policies and limits to manage the credit risk exposure at deal initiation. Subsequent to deal initiation, credit risk at a subscriber level is managed through a combination of policies and procedures which limit the customers' ability to incur further debt should their accounts not be up to date.

The Group calculates an ECL for the instruments in this portfolio in accordance with the simplified approach in IFRS 9 using a provision matrix model which takes into account, among others: roll rates; past performance, incorporated through staging, default and curing definitions; and applicable forward looking indicators in line with Group policy. The Group continually refines and improves the model applied to take into account new information and additional data that becomes available as internal processes evolve. These improvements are accounted for prospectively as changes to the ECL estimate when they arise. Refer to note 3.5.3.

The loss allowance as at 31 May 2022 for advances to customers is determined as follows:

The collateral terms of this arrangement with Cell C are as follows:

• Cell C has stringent requirements for the granting of credit to these customers;
• CEC has direct access to the customer cash flows received by Cell C in respect of the handsets and devices financed;
• CEC has direct access to the customer cash flows received by Cell C in respect of the customer subscriptions; and
• in the unlikely event of default, CEC has the right to sell the customer base.

Once the recoverability of these receivables comes into question, the amount is reclassified to Trade and other receivables, with Cell C as the counterparty.

The movement in ECLs is reflected in the table below:

The effect of credit risk on hedging instruments

On 7 October 2020, The Prepaid Company (TPC) entered into an interest rate swap agreement in respect of its variable rate facility agreement in order to hedge its interest rate risk (refer to note 3.8 for more detail). By using derivative financial instruments to hedge exposures to changes in interest rates, TPC also exposes itself to credit risk of the derivative counterparty, which is not offset by the hedged item. TPC minimises counterparty credit risk in derivative instruments by entering into transactions with high-quality counterparties.

At inception of each hedge, it was determined that the effects of credit risk are not expected to dominate the value changes arising from the hedging relationship as all relevant metrics to demonstrate the existence of an economic relationship have been satisfied.

At each subsequent reporting date, hedge effectiveness for each hedging relationship will be assessed and the effects of credit risk will be considered.
