In this regard, we wish to clarify that the delay in commercial supplies as disclosed by DRL does not have any material impact, financially or otherwise, on our operations. While we stay committed to our long-standing valuable partnership with DRL, we have enough demand for the product from other customers, including for Canada, and our capacities are fully committed. We are also adding significant new capacities starting current quarter and later in the year, in line with our expansion plans, as earlier communicated and thus will be in a position to supply all the demand of DRL as soon as they are ready. We remain focused on executing our growth plans and serving our global customers with high standards of quality, reliability and supply continuity. This is for your information and records.
