This figure represents the estimated volume of retail sales across all hardware platforms (factoring in returns submitted by retail clients in brick-and-mortar as well as digital storefronts), i.e. the “sell-through” figure, less all refund requests e-mailed directly to the Company by the publication date of this report in the framework of the “Help Me Refund” campaign.
