The risks faced by the group as a result of the post-retirement medical aid obligation can be summarised as follows:

Inflation: The risk that future CPI inflation and healthcare cost inflation are higher than expected and uncontrolled.

Longevity: The risk that pensioners live longer than expected and thus their healthcare benefit is payable for longer than expected.

Open-ended, long-term liability: The risk that the liability may be volatile in the future and uncertain.

Future changes in legislation: The risk that changes to legislation with respect to the post-employment liability may increase the liability for Tiger Brands.

Future changes in the tax environment: The risk that changes in the tax legislation governing employee benefits may increase the liability for Tiger Brands.

Perceived inequality between current employees: The risk of dissatisfaction of current employees who are not eligible for a postemployment healthcare subsidy.

Administration: Administration of this liability poses a burden to Tiger Brands.

Enforcement of eligibility criteria and rules: The risk that eligibility criteria and rules are not strictly or consistently enforced.
