35 RETIREMENT BENEFIT INFORMATION
 

Pensions

Assore Limited is a holding company which operates through its joint-venture entities and various subsidiary and associate companies and, as such, does not have any employees.

All subsidiary companies provide retirement benefits through either a defined contribution fund (termed “umbrella fund”) or a defined benefit fund.

Defined contribution fund

The group and employees contribute 10% and 5% of pensionable salary to the umbrella fund respectively. Contributions to the fund amounted to R1,7 million (2018: R2,0 million) and the value amounted to R11,8 million (2018: R14,7 million) at year-end. The decrease in the value of the fund is due to the retrenchments which occurred at Rustenburg Minerals during the year.

Defined benefit — Assore pension fund

In terms of the Pension Funds Act, the Assore pension fund is actuarially valued every three years. The most recently completed statutory actuarial valuation was performed as at 1 July 2017 and revealed a 121,4% funding level. An interim check was performed for funding purposes as at 1 July 2019, which revealed a 134,1% funding level (2018: 129,7%). The financial position of the fund at the dates of the interim funding checks is set out below:

      %           %    
— Expected return on plan assets     8,58           9,51

— Post-retirement interest rate     4,97           4,48    
— Price inflation rate     5,83           6,41    
— Salary inflation rate     6,53           7,41    
— Pension increases     4,37           4,81    

Other assumptions

Mortality rate for members still in service assumed at zero.

Pension mortality PA (90) — ultimate table, adjusted for two years’ additional longevity since the previous year-end.

Merit salary increases per sliding scale depending on age starting at 5,5% per annum below age 25, and reducing to 0,5% above age 50.

Spouse’s benefits for active members — on average, husbands are assumed to be two years older than their wives, and married at date of retirement.

For current pensioners, their actual marital status and, where applicable, the exact age of their spouse has been taken into account.
