STMicroelectronics NV le li-subsidiary tsa eona ("ST") li na le tokelo ea ho etsa liphetoho, litokiso, lintlafatso, lintlafatso, le lintlafatso ho lihlahisoa tsa ST le/kapa tokomaneng ena ka nako efe kapa efe ntle le tsebiso. Bareki ba lokela ho fumana lintlha tsa morao-rao tse amanang le lihlahisoa tsa ST pele ba fana ka litaelo. Lihlahisoa tsa ST li rekisoa ho latela lipehelo le maemo a thekiso ea ST ka nako ea tumello ea taelo.
Bareki ke bona feela ba ikarabellang bakeng sa khetho, khetho le ts'ebeliso ea lihlahisoa tsa ST mme ST ha e na boikarabello bakeng sa thuso ea kopo kapa moralo oa lihlahisoa tsa Bareki.
Ha ho laesense, e hlalositsoeng kapa e boletsoeng, ea tokelo efe kapa efe ea thepa ea mahlale e fanoeng ke ST mona.
Ho rekisoa ha lihlahisoa tsa ST ka litokisetso tse fapaneng le tlhahisoleseding e boletsoeng mona ho tla hlakola waranti leha e le efe e fanoeng ke ST bakeng sa sehlahisoa se joalo.
