Enclosure:  Accounting Standard

                                 Prudential plc

   Economic Capital, Developments in Regulatory and Financial Reporting, and
 Restatement of 2004 Full Year Results under International Financial Reporting
                     Standards and European Embedded Value

Prudential plc publishes today selected 2004 financial information restated
under European Embedded Value (EEV) and International Financial Reporting
Standards (IFRS). The Group's underlying capital strength, cashflow and dividend
policy are not affected by the adoption of either EEV or IFRS.

In addition, we are also explaining the Group's regulatory capital position
under the Financial Groups Directive (FGD) and the Group's economic capital
position as at 31 December 2004.

Prudential's Group Finance Director, Philip Broadley, said: "We are publishing
today a comprehensive picture of the Group's economic and regulatory capital
positions as at 31 December 2004 and the impact of adopting IFRS and EEV on our
2004 financial results. We believe that the presentation of this information
will enable investors to obtain a better understanding of the Group's capital
position and profitability."

European Embedded Value

Prudential believes that the EEV methodology represents an improvement over
existing embedded value reporting methods used across Europe and supports its
introduction. Prudential re-iterates its belief that embedded value reporting
provides investors with a truer measure of the underlying profitability of the
Group's long-term businesses and is a valuable supplement to statutory accounts.

As a signatory to the European CFO (Chief Financial Officers) Forum on European
Embedded Value (EEV) principles, Prudential will adopt EEV methodology for its
2005 year-end results. This will replace the Achieved Profit basis, the current
supplementary basis of reporting. The adoption of the EEV methodology by
Prudential results in a 1% reduction in the Group's total shareholders' funds to
GBP8.5bn and an uplift of 8% in the value of new business for the year ending 31
December 2004 to GBP741m.

The main impact on the results arises from the effect of changes to the assumed
level of locked-in capital allocated to each business, the adoption of
product-specific risk discount rates, and an explicit valuation of the time
value of options and guarantees. The EEV results also include the value of
future profits from service companies (including fund management operations)
that support the Group's long-term businesses and the UK defined benefit
pensions scheme deficit.



International Financial Reporting Standards

From 1 January 2005, all listed European Groups must prepare their financial
statements in accordance with EU approved International Financial Reporting
Standards (IFRS). The IFRS basis replaces the current Modified Statutory Basis.

The Financial Review section of Prudential's 2004 Annual Report gave extensive
explanation of the likely changes, which are confirmed in this announcement.
Restatement under IFRS Phase 1 gives rise to a GBP15m reduction in operating
profit for 2004 and an increase in shareholders funds of GBP470m.

In conjunction with the adoption of IFRS, Prudential has reviewed all its
accounting policies and is changing the method used to determine longer term
returns included within operating profits. This change, which is not required
under IFRS, increases operating profit by GBP91m, offset by a corresponding
reduction in short-term fluctuations in investment returns, leaving total profit
unchanged.

Groups Directive

Under the Insurance Groups Directive (IGD), introduced in January 2001, Group
solvency is calculated by aggregating the surplus capital held in the regulated
subsidiaries, then deducting group borrowings, other than those subordinated
debt issues that qualify as capital.

The Financial Groups Directive (FGD), which has applied to Prudential since 1
January 2005, involves a similar calculation of Group solvency as for the IGD,
but the solvency test under the FGD is a continuous requirement and a regulatory
obligation. Prudential has put in place a regulatory capital projection model
for all business units to ensure that the Group meets, at all times, the
continuous solvency requirements.

As at 31 December 2004, Prudential had a surplus of GBP845m on the IGD basis.

Economic Capital

Prudential has determined its economic capital requirement as the amount of
capital required to ensure that the Group can meet its existing contractual and
discretionary policyholder obligations and remain solvent at all times over a
25-year time horizon, within a strict target solvency level. Economic capital
methodology is different from the regulatory capital model used under IGD and
FGD in that it allows the Group to take account of its geographic spread and its
ability to diversify its risks across its businesses.

Prudential's economic capital model, which it has been developing over the past
three years, is integral to its capital and financial management at both Group
and business unit level. It provides Prudential with a measure of the impact of
taking on different risks in different parts of the world, both in terms of the
extreme events that have the potential to deplete its capital base, and the more
day-to-day volatility to which it is exposed.

As at 31 December 2004, Prudential had available capital of GBP3.4bn. This
represents a surplus of GBP1.6bn over required economic capital of GBP1.8bn.

its future financial condition, performance, results, strategy and objectives.
Statements containing the words "believes", "intends", "expects", "plans",
"seeks" and "anticipates", and words of similar meaning, are forward-looking. By
their nature, all forward-looking statements involve risk and uncertainty
because they relate to future events and circumstances which are beyond

interest rates and exchange rates, and the performance of financial markets
generally; the policies and actions of regulatory authorities, the impact of
competition, inflation, and deflation; experience in particular with regard to

timing, impact and other uncertainties of future acquisitions or combinations
within relevant industries; and the impact of changes in capital, solvency or
accounting standards, and tax and other legislation and regulations in the
jurisdictions in which Prudential and its affiliates operate. This may for
example result in changes to assumptions used for determining results of
operations or re-estimations of reserves for future policy benefits. As a
result, Prudential's actual future financial condition, performance and results
may differ materially from the plans, goals, and expectations set forth in
Prudential's forward-looking statements. Prudential undertakes no obligation to
