Question to the Scotland Office:

To ask the Secretary of State for Scotland, if he will estimate the revenue generated in Scotland by companies that have their headquarters (a) in Scotland and (b) outside of Scotland.

There are no estimates of the number of companies headquartered in Scotland, of the 343,105 enterprises operating in Scotland as at March 2013. Registered private sector enterprises with ultimate ownership outside Scotland accounted for 3.1% of firms, and 58.1% of turnover. This means that 41.9% of business turnover in Scotland is generated by enterprises with ownership in Scotland. These figures come from the Scottish Government publication Businesses in Scotland 2013.
