There is no 'final' target. Foundry losses will cause lowered targets for foundry over time, until some external volume happens, or enough excess fab capacity is sold to other foundries to make the remaining fabs at least break even.
If Products sell then that helps slow down the reductions in ProdCo, but like IFS, ProdCo had an IDM1.0 strategy of maintaining excess capacity at all times. LBT is working to eliminate that persistent level of excess, so targets could be lowered even as business picks up.
Ultimately the company may settle out in the 60k area, after some fab and product group sale and the shut down of groups which can not be sold.
