The attempt on behalf of companies to intentionally hide or withhold information pertaining to business deeds and or transactions=παραλάσσονται. Vs official co-ownership or simultaneous proprietorship and or mutual directorship over deeds, along with an affiliate company or subsidiary=συνέχονται. However, in context, one would probably write "differentiating deeds/actions" or "against which a company would be held severally liable for" (in reference to "παραλλάσονται") and "deeds for which both companies are jointly liable for" (in reference to συνέχονται"), because the text refers to deeds performed and not ownership per se.
