Capital Gains tax on company share save scheme shares

I was part of a company share save scheme ( GE USA) around the year 2000. The scheme worked by allowing employees to purchase shares each payment date from their wages. The Company ( GE ) then matched those shares as part of a buy one get one free agreement. My question is with regards to capital gains on selling these shares. Does HMRC treat ALL these shares as if I had purchased them ? Do the matching shares carry some sort of separate tax situation ?
