To ask the Scottish Executive, further to the answer to question S2W-31693 by Tavish Scott on 19 February 2007, whether the six per cent discount referred to in the answer was itself an index-linked figure.

No. Guidance on use of discount rates is set out in HM Treasury's Guidance on Appraisal and Evaluation in Central Government , known as The Green Book . At the time the Skye Bridge was being planned, The Green Book recommended the use of a discount rate of 6%.
