Full details are available from the ESG Report A4: Price/Mix Price mix is a term used by management and investors to explain the movement in revenue between periods. Revenue is affected by the volume (how many units are sold) and the value (how much is each unit sold for). Price mix is used to explain the value component of the sales as the Group sells each unit for a value (price) but may also achieve a movement in revenue due to the relative proportions of higher value volume sold compared to lower value volume sold (mix). https://www.bat.com/group/sites/UK_9D9KCY.nsf/vwPagesWebLive/DOAWWEKR/$file/BAT_ESG_Report_2019.pdf. A6: Non-Combustible consumers The number of consumers of Non-Combustible products is defined as the estimated number of Legal Age (minimum 18 years, US: 21 years) consumers of the Group's Non- Combustible products. In markets where regular consumer tracking is in place, this estimate is obtained from adult consumer tracking studies conducted by third parties (including Kantar). In markets where regular consumer tracking is not in place, the number of consumers of Non-Combustible products is derived from volume sales of consumables and devices in such markets, using consumption patterns obtained from other similar markets with consumer tracking (utilising studies conducted by third parties including Kantar). The number of Non-Combustible products consumers is used by management to assess the number of consumers regularly using the Group's New Category products as the increase in Non-Combustible products is a key pillar of the Group's ESG Ambition and is integral to the sustainability of our business. The Group's management believes that this measure is useful to investors given the Group's ESG ambition and alignment to the sustainability of the business with respect to the Non-Combustibles portfolio. 40
