NOTES (31-35) TO THE
FINANCIAL STATEMENTS

31.  RETIREMENT BENEFITS (Rmillion)            
                 
   Pension and Provident Fund Schemes 
   Tongaat Hulett contributes towards retirement benefits for substantially all permanent employees who, depending on preference or local legislation, are required to be members of either a Tongaat Hulett implemented scheme or of various designated industry or state schemes. The Tongaat Hulett schemes, which are predominantly defined contribution schemes, are governed by the relevant retirement fund legislation. Their assets consist primarily of listed shares, fixed income securities, property investments and money market instruments and are held separately from those of Tongaat Hulett. The scheme assets are administered by boards of trustees, each of which includes elected employee representatives. 
                 
   Defined Contribution Pension and Provident Schemes             
   The latest audited financial statements of the defined contribution schemes, including the scheme in Swaziland, reflect a satisfactory state of affairs. Contributions of R111 million were expensed during the year (2017: R106 million). 
                 
   Defined Benefit Pension Scheme 
   A defined benefit scheme in South Africa which previously covered the old Tongaat-Hulett Group was split between Tongaat Hulett and Hulamin in 2012 and then in 2013 was converted to a Defined Contribution arrangement for in-service members and the pensioner liabilities were outsourced to an insurer.

   Post-Retirement Medical Aid Benefits 
   In the South African operations, the obligation to pay medical aid contributions after retirement is no longer part of the conditions of employment for employees engaged after 30 June 1996. A number of pensioners and current employees, however, remain entitled to this benefit. The entitlement to this benefit for these current employees is dependent upon the employee remaining in service until retirement. The Zimbabwe operations provide post-retirement medical benefits for pensioners and current employees. In Mozambique, Acucareira de Xinavane subsidises the medical contributions in respect of its pensioners. 
                 
   The unfunded liability for post-retirement medical aid benefits is determined actuarially each year using the projected unit credit method and comprises:

   Key risks associated with the post-retirement medical aid obligation:             
   Higher than expected inflation (to which medical cost/contribution increases are related). 
   "Real" future medical aid cost/contribution inflation (i.e. above price inflation) turns out higher than allowed for. 
   Members/pensioners changing medical aid plans to more expensive plans subject to maximum in terms of policy. 
   Longevity – pensioners (and their dependants) living longer than expected in retirement. 
   Changes in the prescribed basis (as a result of market conditions) which adversely impact the financial results of the company. 
              
              
   Retirement Gratuities             
   Tongaat Hulett has in the past made payments, on retirement, to eligible employees who have remained in service until retirement, and have completed a minimum service period of ten years. The benefit is applicable to employees in the South African and Zimbabwean operations.

   Key risks associated with the retirement gratuity obligation:

   Fewer exits prior to retirement than expected (i.e. more people reach retirement than allowed for in terms of current
demographic assumptions). 
  
   Changes in the prescribed basis (as a result of market conditions) which adversely impact the financial results of the company.

34.  BEE EMPLOYEE SHARE OWNERSHIP PLANS 
                    
   The BEE employee transaction, which comprises the Employee Share Ownership Plan (ESOP) and the Management Share Ownership Plan (MSOP), vested during the year ended 31 March 2013. The ESOP scheme consisted of a share appreciation right scheme and participants shared in 50% of the dividend payable to ordinary shareholders. The MSOP scheme consisted of two components namely a share appreciation right scheme and a share grant scheme. 
  
  
                    
   The ESOP Trust and MSOP Trust were established to acquire and hold Tongaat Hulett Limited shares for the benefit of designated employees. Tongaat Hulett Limited and its subsidiaries made contributions to the MSOP Trust and the ESOP Trust. Due to these shares having specific repurchase rights at maturity (five years from grant date), they were a separate class of restricted shares which, other than for the repurchase terms, ranked pari passu with ordinary shares and became ordinary shares at maturity of the scheme on 1 August 2012. 
                    
   Employee Share Ownership Plan 
                    
   The ESOP Trust has delivered to designated employees all the ordinary shares held in Tongaat Hulett that had been awarded to these employees, leaving a balance of 32 331 ordinary shares that are unallocated.
