What type of fields is "Company"? This could make a huge different based off its type. If it's a single drop-down field then you'd just do a basic filter of FIELD Equal To [cb_myfield] (replace cb_myfield with your actual fields name).
Please note if you're using CB 1.7 then substitutions for drop-down fields are broken and you'll need to see the below bug ticket (fix provided).
