Deciding how to account for public sector financing provided under Private Finance Initiative (PFI) contracts has engendered considerable debate which revolves around whether they should be ‘on balance sheet’ or ‘off balance sheet’. The Accounting Standards Board (ASB) provides the underpinning in FRS 5, interpreted through an ASB Application Note ‘Private Finance Initiative and Similar Contracts’ and the Treasury Technical Note ‘How to Account for PFI Transactions’. This article illustrates the impact of the alternative accountings. It provides an analysis of the annual accounts of two National Health Service (NHS) trusts whose assets are financed through PFI contracts, but which use different accounting approaches. There are considerable difficulties for the user of the accounts when attempting to interpret the comparative financial results of the two trusts in the light of these reporting differences, and the financing of public services is less than adequately reflected in these resource accounting based financial statements.
