1 - Basis of preparation - EEV basis
The summarised consolidated income statement and balance sheet present the Group’s results and financial position for the life and related businesses on the European Embedded Value (EEV) basis and for its non-life businesses on the International Financial Reporting Standards (IFRS) basis. The EEV methodology adopted is in accordance with the EEV Principles introduced by the CFO Forum in May 2004 and the Additional Guidance on EEV Disclosures published by the CFO Forum in October 2005. Detailed information on the basis of preparation and EEV methodology is set out in Aviva plc’s 2007 Report and Accounts; any updates are detailed below.
The directors consider that the EEV methodology represents a more meaningful basis of reporting the value of the Group’s life and related businesses and the drivers of performance than IFRS methodology. This basis allows for the impact of uncertainty in the future investment returns more explicitly and is consistent with the way the business is priced and managed.
At the time the Group adopted EEV principles in 2004, its approach to establishing economic assumptions, including investment returns, required capital and discount rates, was reviewed by Tillinghast, a firm of actuarial consultants. The approach used by the Group is based on the established “capital asset pricing model” theory and remains in line with EEV principles and guidance.
The results for the six month periods to 30 June 2008 and 30 June 2007 are unaudited but have been reviewed by Ernst & Young LLP. Their independent report in respect of 30 June 2008 is included in the Group’s half year report of that document. The half year accounts for the six months ended 30 June 2008 do not constitute statutory accounts as defined in Section 240 of the Companies Act 1985.
Covered business
Covered business includes the Group’s share of our joint venture operations including our arrangement with The Royal Bank of Scotland Group (RBSG) and our operations in India, China, Turkey, Malaysia, Taiwan and South Korea.
Risk discount rates
Following review at 30 June 2008, the directors have decided to maintain the life embedded value risk margin at 2.7%. The market assessed risk factor (beta) has reduced since the initial risk margin was originally set, implying a reduction of the risk in the life business. Management will keep the risk margin under review and will make adjustments as necessary to reflect past trends and future expected trends in the riskiness of the life business, based on the beta.
The sensitivity disclosures indicate the impact to the embedded value that would arise from a change in the risk discount rate.
