Toshiba Corp has cut its planned capital spending for the year to March 31 1993 to $1,200m from the $1,440m projected in May, citing its worsening profit outlook as the main reason: it plans to cut investment in development of large-scale integrated circuits by $160m, in part to avoid duplication of effort following its agreement to co-operate with IBM Corp and Siemens AG on 256M-bit memory chips.
