The following table provides an analysis of financial instruments that are measured subsequent to initial recognition at fair value, grouped into levels 1 to 3 based on the degree to which the fair value is observable, or based on observable inputs:

The fair values of financial assets and liabilities are based on quoted market prices where available. Where the market value is not available, the Group has estimated relevant fair values on the basis of available information from outside sources.

For all level 3 fair value measurements, a change to one or more of these unobservable inputs to reflect a reasonably possible alternative assumption would not result in a significant change to the fair value.
