31. RISK MANAGEMENT
 

Overall risk management programme

The Group’s overall financial risk management programme focuses, inter alia, on the unpredictability of financial markets and seeks to minimise potential adverse effects on the Group’s financial performance. The Group does not apply formal hedge accounting but uses derivative financial instruments to hedge interest and foreign currency risk exposures. Financial risk management is carried out by a central treasury department (treasury) under policies approved by the investment committee. Treasury identifies, evaluates and economically hedges financial risks in close cooperation with the Group’s operating units. The Group has written principles for overall financial risk management, as well as written policies covering specific areas, such as foreign exchange risk, interest rate risk, credit risk, use of derivative financial instruments and non-derivative financial instruments, and investment of excess liquidity.

Capital risk management

The Group’s objective when managing capital is to safeguard the Group’s ability to continue as a going concern in order to provide returns for shareholders and benefits for other stakeholders and to provide for sufficient capital expansion. The capital structure of the Group consists of debt, which includes the borrowings disclosed in note 21, cash and cash equivalents disclosed in note 15 and equity as disclosed in the statement of financial position. Preference shares are included in borrowings. The Group uses the net debt to normalised EBITDA ratio to measure the funding requirements in the form of debt or equity.

The ratio is calculated as net debt divided by normalised EBITDA. Net debt is calculated as total interest-bearing borrowings (including current interest-bearing and non-current interest-bearing borrowings as shown in the statement of financial position) plus guarantees (if applicable) less net cash and cash equivalents. Normalised EBITDA is defined, in the debt agreements, as earnings before interest, tax, depreciation and amortisation, adjusted for non-recurring items and including the EBITDA of new acquisitions for that part of the year when it was not owned by the Group.

In order to maintain or adjust the capital structure, the Group may adjust the amount of distributions paid to shareholders, return capital to shareholders, issue new shares or sell assets to manage the debt level.

There have been no changes to what the Group manages as capital, the strategy for capital maintenance or externally imposed capital requirements from the previous year. Although the implementation of IFRS 16 Leases has an immaterial impact on the covenants, the Group has had initial discussions with the lenders to potentially adjust the calculations.

Financial risk

The Group’s activities expose it to a variety of financial risks: market risk (including foreign exchange risk, fair value interest rate risk and cash flow interest rate risk), credit risk, liquidity risk and fair value risk.

Market risk

Foreign exchange risk

 

Risk exposure

 

The Group interacts with international suppliers and is exposed to foreign exchange risk arising from various currency exposures. The foreign currency transactions are mainly denominated in:

  • Pound sterling;
  • European euro; and
  • US dollar.

The Group’s presentation currency is the South African rand, but as it operates internationally with investments in foreign operations, it is exposed to a number of currencies, of which the exposure to the Botswana pula (BWP), pound sterling (GBP), US dollar (USD), European euro (EUR), Swiss franc (CHF) and Polish zloty (PLN) are the most significant.

 

How the risk arises

 

Foreign exchange risk arises when future commercial transactions or recognised assets or liabilities are denominated in a currency that is not the entity’s functional currency and from net investments in foreign operations. These transactions include certain intercompany loans which expose the Group to foreign exchange risk.

 

Objectives, policies and processes for managing the risk and methods used to measure risk

 

The Group has set up a policy to require Group companies to manage their foreign exchange risk against their functional currency. The Group’s treasury risk management principle is to hedge material cash flows where the local cash flow impact is in excess of 5 million (2018: 5 million) functional currency denomination. The Group companies are required to economically hedge their foreign exchange risk exposure in consultation with treasury. To manage their foreign exchange risk arising from future commercial transactions and recognised assets and liabilities, entities in the Group use forward contracts and options, transacted with commercial banks on an all-inclusive price in the companies’ functional currency.

Currency exposure arising from the net assets of the Group’s foreign operations is managed primarily through borrowings denominated in the relevant foreign currencies, as and when it is required. At 30 September 2019, foreign denominated borrowings to the equivalent of R7 800 million existed (2018: R8 161 million).

The Group reviews its foreign currency exposure, including commitments, on an ongoing basis.

 

Concentration of risk

 

The Group has investments in foreign operations in Botswana, the United Kingdom, Italy, Spain, Switzerland, northern Europe, Ireland and Poland. The net assets of the Botswana, United Kingdom, Italy, Spain, Switzerland, northern Europe, Ireland and Polish investments are exposed to foreign currency translation risk as the companies are subsidiaries of the Group.

Interest rate risk

  Risk exposure   Borrowings issued at variable rates expose the Group to cash flow interest rate risk. Borrowings issued at fixed rates economically expose the Group to fair value interest rate risk. Refer note 21.
  How the risk arises   The Group’s interest rate risk primarily arises from a mix of short and long-term borrowings. The Group’s income and operating cash flows are substantially independent of changes in market interest rates. Refer to note 15.
  Objectives, policies and processes for managing the risk and methods used to measure risk   The Group manages its interest rate exposure in total and mainly borrows or invests as far as possible at Group level, unless it is more appropriate to do so at subsidiary level. Based on the various scenarios, the Group manages its cash flow interest rate risk by using interest rate collars, caps and swaps. Such interest rate hedges have the economic effect of capping the exposure to floating rates to a maximum rate. Generally, the Group raises long-term borrowings at floating rates and then hedges floating rates to a known maximum exposure. Under the interest rate collars, caps and swaps, the Group agrees with other parties to exchange, at specified intervals (primarily quarterly), the difference between the hedge and the floating rate interest amounts calculated by reference to the agreed notional amounts. Swaps are entered into to fix interest rates from floating rates.
  Concentration of risk   Group policy is to hedge a maximum of 80% of its borrowings and to hedge a quantum of borrowings to ensure the profit or loss impact of a 1% movement in interest rates on unhedged borrowings is less than 2.0% of the previous 12-month Group normalised EBITDA. At 30 September 2019, 42% of the Group debt was hedged (2018: 33%). Refer to note 23 for the current interest rate hedges in place.

The Group analyses its interest rate exposure on a dynamic basis. Various scenarios are simulated taking into consideration refinancing, renewal of existing positions, alternative financing and hedging. Based on these scenarios, the Group calculates the impact on profit or loss of a defined interest rate shift. For each simulation, the same interest rate shift is used for all currencies. The scenarios are run only for liabilities that represent the major interest-bearing positions.

The simulation is done on a quarterly basis to verify that the maximum loss potential is within the Group’s limits. The Group’s debt is partially hedged by interest rate swap contracts. The interest rate swap contracts hedge R5.3 billion (2018: R4.7 billion) of the variable interest rate outstanding balance of Group debt of R11 289 million (2018: R12 690 million).

Liquidity risk

  Risk exposure   Those financial liabilities of the Group with contractual cash flows and maturity dates are exposed to liquidity risk.
  How the risk arises   Liquidity risk arises should the Group not be able to meet its obligations as they become due.
  Objectives, policies and processes for managing the risk and methods used to measure risk  

Prudent liquidity risk management implies maintaining sufficient cash and marketable securities, the availability of funding through an adequate amount of committed credit facilities and the ability to close out market positions. The Group’s liquidity risk is mitigated by the availability of funds to cover future commitments. The Group manages liquidity risk through an ongoing review of future commitments and credit facilities. Due to the dynamic nature of the underlying businesses, treasury maintains flexibility in funding by maintaining availability under committed credit lines.

The Group has sufficient available bank facilities that can be utilised to service short-term commitments. Refer note 21.

Cash flow forecasts are prepared and utilised borrowing facilities are monitored on a daily basis. Longer-term cash flow forecasts are updated quarterly.

Credit risk

 

Risk exposure

 

Credit risk arises mainly from cash and cash equivalents, trade and other receivables and other assets.

Trade receivables comprise a widespread customer base.

  How the risk arises  

Credit risk is the risk of financial loss due to counterparties to financial instruments not meeting their contractual obligations.

 

Objectives, policies and processes for managing the risk and methods used to measure risk

 

Credit risk is managed using Group policies within the territories it arises.

The Group deposits the surplus cash with major banks with high-quality credit standing and maintains an appropriate spread of cash deposits between various financial institutions to limit the exposure to any one counterparty. For banks and financial institutions, only independently rated parties with a minimum Moody’s rating “Baa+” for South African banks are accepted. For both Alliance Medical and Poland, counterparty risk is managed through the active monitoring and management of counterparties with which Alliance Medical and Poland transact.

The Group evaluates credit risk relating to customers on an ongoing basis. If customers are independently rated, these ratings are used. If there is no independent rating, risk control assesses the credit quality of the customer, taking into account its financial position, past experience and other factors. Individual risk limits are set for patients without medical aid insurance. Services to customers without medical aid insurance are settled in cash or using major credit cards on discharge date as far as possible. Credit guarantee insurance is not purchased.

In certain Alliance Medical territories, use is made of invoice factoring facilities which are on a non-recourse basis, further reducing the credit risk from individual customers.

 

Concerntration of risk

 

The maximum exposures to credit risk at the reporting date are cash and cash equivalents as well as the carrying value of each class of trade and other receivables and other assets. The Group does not hold any collateral as security. The Group is exposed to a number of guarantees for the overdraft facilities of Group companies. Refer to note 29 for additional details.

 

Maximum exposure to credit risk by class of financial instrument

 

Financial assets exposed to credit risk at year-end were as follows:

Trade and other receivables 3 747   3 636  
Cash and cash equivalents 1 544   1 494  
Other assets 87   177  
 

Credit quality analysis of financial assets that are neither past due nor impaired (applied before 1 October 2018)

 

The credit quality of trade and other receivables that are neither past due nor impaired can be assessed by reference to historical information about counterparty default rates. No material historical default rates exist that require additional impairments.

The Group does not expect any significant loss from non-performance by counterparties on credit granted that has not been provided for.

Amounts owing by associates and joint ventures are interest-bearing at rates negotiated on an annual basis (2019: 10.00% and 2018: 10.00%) and are repayable on terms agreed by the associate and/or joint venture company’s directors. The credit quality of these loans is determined based on past default rates taking into account expected changes in the economic environment. No such defaults existed in the past.

The cash and cash equivalents carrying amount is denominated in the following currencies:

3 The counterparties have a minimum Fitch credit rating of BBB- (2018: BB-).
4 The counterparties have a minimum Polish Fitch rating of B (2018: B).

Trade and other receivables

An impairment analysis is performed at each reporting date using a provision matrix to measure expected credit losses (ECLs). The provision rates are based on days past due for groupings of various customer segments with similar loss patterns (mainly by customer type).

The calculation reflects the probability-weighted outcome, the time value of money and reasonable and supportable information that is available at the reporting date about past events, current conditions and forecasts of future economic conditions. Generally, trade receivables are written off when the Group has exhausted all options regarding the debt.

Refer Annexure A – significant accounting policies (section 1.11 financial instruments).

The maximum exposure to credit risk at the reporting date is the carrying value of each class of financial assets disclosed in this note. The Group does not hold collateral as security.

1 Due to the nature of Alliance Medical’s business the key customers are, or are funded by, government-funded public bodies such as NHS trusts in the UK or ASL bodies in Italy, and therefore the nature of these organisations further reduces the susceptibility to credit risk. In certain territories, use is made of invoice factoring facilities which are on a non-recourse basis, further reducing the credit risk from individual customers. As such any further detailed analysis of the credit risk of the financial assets by category was not considered meaningful in prior years.

Fair value

The derivative assets and liabilities used for hedging, as presented in the statement of financial position, are the financial assets and liabilities that are measured at fair value.

The fair values of quoted investments are based on current bid prices. If the market for a financial asset is not active and for unlisted securities, the Group establishes fair value by using valuation techniques. These include the use of recent arm’s length transactions, reference to other instruments that are substantially the same, discounted cash flow analysis and option pricing models, making maximum use of market inputs and relying as little as possible on entity-specific inputs.

The Group’s financial instruments held at fair value, are measured subsequent to their initial recognition and are grouped into levels 1 to 3 based on the extent to which the fair values are observable. All of the resulting fair value estimates for the derivatives used for hedging are included in level 2. The contingent considerations are included in level 3. The fair value of interest rate swaps is calculated as the mark-to-market valuation, which represents the mid-market value of the instrument as determined by the financial institution at 30 September 2019.

The fair value of forward exchange contracts is determined using forward exchange rates at the statement of financial position date, with the resulting value discounted back to the present value, as determined by the financial institution at 30 September 2019.

There were no transfers between levels 1, 2 and 3 during the year.
