The Group uses the following hierarchy for determining and disclosing the fair value of financial instruments identified below. The table below reflects ‘Financial instruments’ and ‘Non-current assets classified as held for sale’ carried at fair value, and those ‘Financial instruments’ and ‘Non-current assets classified as held for sale’ that have carrying amounts that differ from their fair values, in the Statement of Financial Position:    
                                                                 
Level 1: quoted (unadjusted) prices in active markets for identical assets or liabilities;    
Level 2: other techniques for which all inputs that have a significant effect on the recorded fair value are observable, either directly or indirectly; and    
Level 3: techniques that use inputs that have a significant effect on the recorded fair value that are not based on observable market data.

The Group’s unlisted investments in insurance cell-captives were previously categorised within Level 2 of the fair value hierarchy. Due to the unobservability of the lowest level input that is significant to the entire valuation the financial assets were re-categorised to Level 3. Other than this transfer, there were no further transfers between Level 1, Level 2 and Level 3 fair value categories during the financial period.    
The financial assets and financial liabilities have been presented based on an analysis of their respective natures, characteristics and risks.    
The valuation techniques and significant inputs driving the fair value determination have remained unchanged since the Group’s December 2019 year-end. For more detail in this regard, refer to the 2019 Massmart Group audited consolidated annual financial statements available on the Group’s website.    
The Group has considered the significant unobservable inputs, the sensitivities attached to them as well as any possible interrelationship between significant unobservable inputs. Currently it is assessed that no such material inputs exist and that no reasonable movement in such an input would result in a material impact for the Group.
