I'm a bit unsure about the sense of the sentence as a whole. Here is the context:
Das strategische Management von TC hat es geschafft, die Kultur zu einem Wertfaktor auszubauen. "Ihr verdankt TC das grosse Involement der Mitarbeiter, die eigene Stockholder-Struktur, die Flexibilität der Produktion und Mitarbeiter."
"TC has this (the strategic management?) to thank for the committed involvement of the employees, the individual (?) stockholder structure, and the flexibility of production and employees."
Any comments would be very welcome, thanks!
