In late November 2020, we began shipping product inventory which had been stored at the plant.
We have discussed with our customers about the possibility of switching to alternative products, and requested other semiconductor manufacturers to supply such alternative products to our customers where possible.
Regarding cases where alternative products are unavailable, we are advancing preparations for substitute manufacturing.
Currently, several semiconductor manufacturers are cooperating with this endeavor regarding certain products.
