Borrowing by the Crown is, under Section 55 of the Public Finance Act 1989, a charge on the revenue of the Crown equally and rateably. Therefore no property, plant and equipment owned by the Core Crown has been pledged as security for liabilities. Government-owned property plant and equipment is however subject to a significant number of legislative and policy restrictions with respect to its use and disposal.
These carrying values critically depend on judgments of useful lives to determine depreciation and the assumptions used in revaluations. Depreciation rates are affirmed to be appropriate each year by those responsible for managing the assets, whereas assurance on the assumptions used in valuations is provided by the use of independent valuers as noted below.
