European Embedded Value (EEV) Basis Results

BASIS OF PREPARATION

IFRS profit for long-term business broadly reflects the aggregate of results on a traditional accounting basis. By contrast, EEV is a way of measuring the value of the in-force life insurance business. The value of future new business is excluded from the embedded value. The EEV Principles provide consistent definitions of the components of EEV, a framework for setting assumptions and an approach to the underlying methodology and disclosures. Results prepared under the EEV Principles represent the present value of the shareholders' interest in the post-tax future profits (on a local statutory basis) expected to arise from the current book of long-term business, after sufficient allowance has been made for the aggregate risks in the business. The shareholders' interest in the Group's long-term business is the sum of the shareholders' total net worth and the value of in-force business.

For the purposes of preparing EEV basis results, insurance joint ventures and associates are included at the Group's proportionate share of their embedded value and not at their market value. Asset management and other non-insurance subsidiaries, joint ventures and associates are included in the EEV basis results at the Group's proportionate share of IFRS basis shareholders' equity, with central Group debt shown on a market value basis.

Key features of the Group's EEV methodology include:

- Economic assumptions: The projected post-tax profits assume a level of future investment return and are discounted using a risk discount rate. Both the risk discount rate and the investment return assumptions are updated at each valuation date to reflect current market risk-free rates, such that changes in market risk-free rates impact all projected future cash flows. Risk-free rates, and hence investment return assumptions, are based on observable market data, with current market risk-free rates assumed to remain constant throughout the projection, with no trending or mean reversion to longer-term assumptions. Different products will be sensitive to different assumptions, for example, spread-based products or products with guarantees are likely to benefit disproportionately from higher assumed investment returns.

- Time value of financial options and guarantees: Explicit quantified allowances are made for the time value of financial options and guarantees (TVOG). The TVOG is determined by weighting the probability of outcomes across a large number of different economic scenarios and is typically less applicable to health and protection business that generally contains more limited financial options or guarantees.

- Allowance for risk in the risk discount rates: Risk discount rates are set equal to the risk-free rate at the valuation date plus product-specific allowances for market and non-market risks. Risks that are explicitly captured elsewhere, such as via the TVOG, are not included in the risk discount rates. The allowance for market risk is based on a product-by-product assessment of the sensitivity of shareholder cash flows to varying market returns. This approach reflects the inherent market risk in each product group and results in lower risk discount rates for products where the majority of shareholder profit is uncorrelated to market risk and appropriately higher risk discount rates for products where there is greater market exposure for shareholders. For example, the major sources of shareholder profits for health and protection products are underwriting profits or fixed shareholder charges which are less sensitive to market risk. For unit-linked products where fund management charges fluctuate with the investment return a portion of the profits will typically be more sensitive to market risk compared to health and protection products due to the higher proportion of equity-type assets in the investment portfolio. The construct of UK-style with-profits funds in some business units reduce the market volatility of both policyholder and shareholder cash flows due to smoothed bonus declarations and for some markets the presence of an estate. The allowance for non-market risk comprises a base Group-wide allowance of 50 basis points plus additional allowances for emerging market risk where appropriate. At 30 June 2021, the total allowance for non-market risk is equivalent to a $(3.4) billion (full year 2020: $(3.2) billion) reduction, or around (8) per cent (full year 2020: (7) per cent) of the embedded value.

Following its classification as held for distribution, the US operations have been included at their estimated fair value at 30 June 2021. Further information is contained in note 4.

EEV RESULTS HIGHLIGHTS FOR CONTINUING OPERATIONS

* Re-presented to include amounts relating to Africa.

Notes

(i) The results above are for the Group's continuing operations only, excluding results from the US operations which were classified as discontinued operations at 30 June 2021. The 2020 comparative results have been re-presented accordingly. Further information is provided in note D1.2 of the IFRS financial statements.

(ii) The Group has changed its operating segments from 2021, as discussed in note B1.3 of the IFRS financial statements, with Africa operations included in long-term business.

(iii) Operating free surplus generated is for long-term and asset management businesses only, before restructuring and IFRS 17 implementation costs, centrally incurred costs and eliminations.

(iv) Group EEV operating profit is stated after central expenditure, restructuring and IFRS 17 implementation costs.

(v) Segment results are before deducting the amounts attributable to non-controlling interests. This presentation is applied consistently throughout this document.

MOVEMENT IN GROUP EEV SHAREHOLDERS' EQUITY

Notes

(i) Discontinued operations relate to the Group's US operations which were held for distribution at 30 June 2021 and are included within the Group's EEV results at fair value, consistent with IFRS. Further information is provided in note D1.2 of the IFRS financial statements. The 2020 comparative results have been re-presented to show these operations as discontinued accordingly.

(ii) Intra-group dividends represent dividends that have been declared in the period. Investment in operations reflects movements in share capital.

(iii) Other movements include reserve movements in respect of share capital subscribed, share-based payments, treasury shares and intra-group transfers between operations that have no overall effect on the Group's shareholders' equity.

(iv) Equity items from discontinued US operations include mark-to-market value movements on assets backing net worth of $(240) million for half year 2021 (half year 2020: $317 million; full year 2020: $552 million). In addition, full year 2020 included a charge of $(1,112) million relating to the day one impact of the equity investment by Athene into the US business in July 2020.

(v) Based on the number of issued shares at 30 June 2021 of 2,616 million shares (30 June 2020: 2,609 million shares; 31 December 2020: 2,609 million shares).

(vi) Based on weighted average number of issued shares of 2,601 million shares in half year 2021 (half year 2020: 2,596 million shares; full year 2020: 2,597 million shares).

MOVEMENT IN GROUP FREE SURPLUS

For long-term business, free surplus is the excess of the regulatory basis net assets for EEV reporting purposes (total net worth) over the capital required to support the covered business. Where appropriate, adjustments are made to total net worth so that backing assets are included at market value, rather than at cost, to comply with the EEV Principles. In general, assets deemed to be inadmissible on a local regulatory basis are included in total net worth where considered recognisable on an EEV basis.

Free surplus for asset management and other non-insurance operations (including the Group's central operations) is taken to be IFRS basis shareholders' equity, net of goodwill attributable to equity holders, with central Group debt recorded as free surplus to the extent that it is classified as capital resources under the Group's capital regime. The Group-wide Supervision (GWS) Framework became effective for Prudential upon designation by the Hong Kong IA on 14 May 2021. Under the GWS Framework, all debt instruments (senior and subordinated) issued by Prudential plc at the date of designation meet the transitional conditions set by the Hong Kong IA and are treated as capital resources for the purpose of free surplus at 30 June 2021.

A reconciliation of EEV free surplus to the GWS shareholder capital surplus over group minimum capital requirements is set out in note I(i) of the additional financial information. Further information is provided in note 4 and note 5.

* Before amounts attributable to non-controlling interests.

Notes

(i) Discontinued operations relate to the Group's US operations which were held for distribution at 30 June 2021 and are included within the Group's free surplus at fair value, consistent with IFRS. Further information is provided in note D1.2 of the IFRS financial statements. The free surplus generated of $1,303 million for half year 2021 represents the net effect of the result for the period and the adjustment to reflect the fair value at 30 June 2021. It is not representative of the capital generation in the period for the US operations. The 2020 comparative results have been re-presented to show these operations as discontinued accordingly.

(ii) Free surplus invested in new business primarily represents acquisition costs and amounts set aside for required capital.

(iii) Non-operating free surplus generation in full year 2020 included a reinsurance commission of $770 million received as part of a reinsurance transaction undertaken by our business in Hong Kong as described in note D1.1 of the IFRS financial statements. During half year 2021, the treaty resulted in $(37) million being due to the reinsurer for surpluses arising on the policies being reinsured, which is included within non-operating free surplus generation. The surpluses generated from the underlying in-force reinsured policies continue to be recognised as operating free surplus generated. Non-operating free surplus generated for other operations represents the post-tax IFRS basis short-term fluctuations in investment returns and gain or loss on corporate transactions for other entities.

(iv) Net cash flows to parent company reflect the cash remittances as included in the holding company cash flow at transaction rates. The difference to the intra-group dividends and investment in operations in the movement in EEV shareholders' equity primarily relates to intra-group loans, foreign exchange and other non-cash items.

(v) Equity items from discontinued US operations include the mark-to-market value movements on assets backing net worth of $(270) million for half year 2021 (half year 2020: $317 million; full year 2020: $552 million). In addition, full year 2020 included a credit of $63 million relating to the day one impact of the equity investment by Athene into the US business in July 2020.

NOTES ON THE EEV BASIS RESULTS

1 Analysis of new business profit and EEV for long-term business operations

* Restated to include amounts relating to Africa.

Note

The movement in new business profit from continuing long-term operations is analysed as follows:

2 Analysis of movement in net worth and value of in-force business for long-term business operations

Notes

(i) The total embedded value for continuing long-term business operations at the end of each period show below, excluding goodwill attributable to equity holders, can be analysed further as follows:

* The time value of options and guarantees (TVOG) arises from the variability of economic outcomes in the future and is, where appropriate, calculated as the difference between an average outcome across a range of economic scenarios, calibrated around a central scenario, and the outcome from the central economic scenario, as described in note 7(i)(d). At 30 June 2021, the TVOG for continuing operations is $(719) million, with the substantial majority arising in Hong Kong. The TVOG has decreased since 31 December 2020 reflecting the generally higher government bond yields at 30 June 2021 which mean guarantees are less likely to be in-the-money. The TVOG reflects the variability of guaranteed benefit pay-outs across the range of economic scenarios around interest rates at the valuation date and represents some of the market risk for the key products in Hong Kong. As this market risk is explicitly allowed for via the TVOG, no further adjustment is made for this within the EEV risk discount rate, as described in note 7(i)(h). The magnitude of the TVOG at 30 June 2021 would be approximately equivalent to a 10 basis point (full year 2020: 30 basis point) increase in the weighted average risk discount rate which has increased 60 basis points since 31 December 2020.

(ii) The expected return on existing business reflects the effect of changes in economic and operating assumptions in the current period, as described in note 7(ii)(c). The movement in this amount compared to the prior period from continuing long-term operations is analysed as follows:

(iii) The effect of changes in operating assumptions was $37 million in the first half of 2021 (half year 2020: $118 million; full year 2020: $390 million from continuing operations) representing a number of individually small items including tax changes arising in the period. Experience variances and other items of $(64) million (half year 2020: $122 million; full year 2020: $135 million from continuing operations) has been driven primarily by increased ecosystem and other investment spend and short-term persistency impacts linked to Covid-19-related impacts. Half year 2021 saw a more normalised level of medical reimbursement compared to 2020, when claims were more significantly reduced by customers either not seeking or deferring insured treatments. There have also been higher Covid-19-related claims in Indonesia.

(iv) The EEV non-operating profit (loss) from continuing long-term operations can be summarised as follows:

(a) The charge of $(866) million in short-term fluctuations in investment returns mainly reflects lower than expected bond returns in a number of markets.

(b) The credit for effect of change in economic assumptions of $914 million primarily arises from increases in long-term interest rates, resulting in higher assumed fund earned rates that impact projected future cash flows across many of the local business units, partially offset by the effect of higher risk discount rates.

(c) Loss attaching to corporate transactions of $(91) million at full year 2020 represents loss from the reinsurance transaction undertaken by our business in Hong Kong described in note D1.1 of the IFRS financial statements.

(v) Other movements include reserve movements in respect of share capital subscribed, share-based payments, treasury shares, intra-group loans and other intra-group transfers between operations that have no overall effect on the Group's shareholders' equity.

3 Sensitivity of results for long-term business operations to alternative economic assumptions

The tables below show the sensitivity of the embedded value and the new business profit for continuing long-term business operations to:

- 1 per cent and 2 per cent increases in interest rates and 0.5 per cent decrease in interest rates. This allows for consequential changes in the assumed investment returns for all asset classes, market values of fixed interest assets, local statutory reserves, capital requirements and risk discount rates (but excludes changes in the allowance for market risk);

- 1 per cent rise in equity and property yields;

- 1 per cent and 2 per cent increases in the risk discount rates. The main driver for changes in the risk discount rates from period to period is changes in interest rates, the impact of which is expected to be partially offset by a corresponding change in assumed investment returns, the effect of which is not included in the risk discount rate sensitivities. The impact of higher investment returns can be approximated as the difference between the sensitivity to increases in interest rates and the sensitivity to increases in risk discount rates;

- 20 per cent fall in the market value of equity and property assets (embedded value only); and

- Holding the group minimum capital requirements under the GWS Framework in contrast to EEV basis required capital (embedded value only). This reduces the level of capital and therefore the level of charge deducted from the embedded value for the cost of locked-in required capital. This has the effect of increasing EEV.

The sensitivities shown below are for the impact of instantaneous and permanent changes (with no trending or mean reversion) on the embedded value of long-term business operations and include the combined effect on the value of in-force business and net assets (including derivatives) held at the valuation dates indicated. The results only allow for limited management actions, such as changes to future policyholder bonuses, where applicable. If such economic conditions persisted, the financial impacts may differ to the instantaneous impacts shown below. In this case, management could also take additional actions to help mitigate the impact of these stresses. No change in the mix of the asset portfolio held at the valuation date is assumed when calculating sensitivities, while changes in the market value of those assets are recognised. The sensitivity impacts are expected to be non-linear. To aid understanding of this non linearity, impacts of both a 1 per cent and 2 per cent increase to interest rates and risk discount rates are shown.

If the changes in assumptions shown in the sensitivities were to occur, the effects shown below would be recorded within two components of the profit analysis for the following period, namely the effect of changes in economic assumptions and short-term fluctuations in investment returns. In addition to the sensitivity effects shown below, the other components of the profit for the following period would be calculated by reference to the altered assumptions, for example new business profit and expected return on existing business.

* Half year 2021 new business profit includes Africa operations following the change in the Group's operating segments in 2021. In the context of the Group, Africa's results are not materially impacted by the above sensitivities.

* Embedded value includes Africa operations following the change in the Group's operating segments in 2021. In the context of the Group, Africa's results are not materially impacted by the above sensitivities.

Overall, the new business profit sensitivities at 30 June 2021 are in line with those at 31 December 2020 after allowing for the level of new business profit at a half year compared to a full year.

The interest rate sensitivities illustrate the impact of using different economic assumptions within our EEV framework. At the current and higher interest rates at 30 June 2021 there is a reduced benefit from further increases in investment returns compared to 31 December 2020 as guarantees written to policyholders are less likely to be in-the-money at current levels. This contrasts with the adverse effect of higher risk discount rates which tends to be more stable from period to period all other things being equal. For a 1 per cent increase in assumed interest rates the net $(1,986) million negative effect comprises a $(5,307) million negative impact of increasing the risk discount rate by 1 per cent, partially offset by a $3,321 million benefit from assuming 1 per cent higher investment returns. Similarly, for a 2 per cent increase in assumed interest rates the net $(4,477) million negative effect comprises a $(9,403) million negative impact of increasing the risk discount rates by 2 per cent, partially offset by a $4,926 million benefit from higher assumed investment returns. Finally, for a 0.5 per cent decrease in assumed interest rates, there would be a net $(84) million negative effect from the 0.5 per cent reduction in investment returns, leading to guarantees becoming more likely to be in-the-money, being partially offset by the reduction in assumed discount rates. These offsetting impacts are sensitive to economics and the net impact can therefore change from period to period depending on the current level of interest rates. For a 1 per cent increase in the assumed Asia equity risk premium and property risk premium the embedded value would increase by $1,725 million.

In order to illustrate the impact of varying specific economic assumptions, all other assumptions are held constant in the sensitivities above and therefore, the actual changes in embedded value were these economic effects to materialise may differ from the sensitivities shown. For example, if interest rates increased by 1 per cent, as well as changes to the risk-free rate, market risk allowances would likely be increased within the risk discount rate, leading to a reduction of $(2,550) million (compared to the $(1,986) million impact shown above). However, if interest rates actually decreased by 0.5 per cent, it would lead to a $202 million increase (compared to the $(84) million impact shown above).

4 EEV basis results for other operations

EEV basis other income and expenditure represents the post-tax IFRS basis results for other operations (before restructuring and IFRS 17 implementation costs), together with an adjustment to deduct the unwind of expected margins on the internal management of the assets of the continuing covered business, as shown in the table below. It mainly includes interest costs on core structural borrowings and corporate expenditure for head office functions in London and Hong Kong that is not recharged/allocated to the insurance operations.

In line with the EEV Principles, the allowance for the future costs of internal asset management services within the EEV basis results for long-term insurance operations excludes the projected future profits or losses generated by any non-insurance entities within the Group in providing those services (ie the EEV for long-term insurance operations assumes that the cost of internal asset management services will be that incurred by the Group as a whole, not the cost that will be borne by the insurance business). The results of the Group's asset management operations include the current period profit from the management of both internal and external funds, consistent with their presentation within the Group's IFRS basis reporting. An adjustment is accordingly made to Group EEV operating profit, within the EEV basis results for other operations, to deduct the expected profit anticipated to arise in the current period in the opening value of in-force business from internal asset management services, such that Group EEV operating profit includes the actual profit earned in respect of the management of these assets.

Any costs incurred within the head office functions in London and Hong Kong that are attributable to the long-term insurance (covered) business are recharged/allocated to the insurance operations and recorded within the results for those operations. The assumed future expenses within the value of in-force business for long-term insurance operations allow for amounts expected to be recharged/allocated by the head office functions. Other costs that are not recharged/allocated to the insurance operations are shown as part of other income and expenditure for the current period, and are not included within the projection of future expenses for in-force insurance business.

* As recorded in note B1.1 of the IFRS financial statements.

The EEV basis shareholders' equity for other operations is taken to be IFRS basis shareholders' equity, with central Group debt shown on a market value basis. Free surplus for other operations is taken to be IFRS basis shareholders' equity, net of goodwill attributable to equity holders, with central Group debt recorded as free surplus to the extent that it is classified as capital resources under the Group's capital regime. Under the GWS Framework, all debt instruments issued by Prudential plc at the date of designation meet the transitional conditions set by the Hong Kong IA and are included as capital resources.

Shareholders' equity for other operations can be compared across metrics as shown in the table below.

* As recorded in note C1 of the IFRS financial statements.

Treatment of US operations following planned demerger

Following its classification as held for distribution, the Group's interest in US operations has been written down to its estimated fair value at 30 June 2021. The fair value has been determined with reference to a valuation range determined by considering publicly available information on listed equities of similar profile to Jackson in the US market. As Jackson is an unlisted entity, the fair value of the Group's interest is inherently uncertain. On completion of the proposed demerger Jackson will become a separately listed entity and its market value will become directly observable, which may differ from the current estimate.

On completion of the proposed demerger the Group's pre-demerger interest in Jackson will be remeasured to its observable fair value at that date, with any remeasurement gain or loss recognised in the results of discontinued operations. At the same time, the fair value of the interest in Jackson distributed to the Group's shareholders will be recognised directly as a reduction in Group equity. The Group intends to retain a 19.9 per cent voting interest (19.7 per cent economic interest) of Jackson post the demerger. This will be measured at fair value within the EEV results going forward.

5 Net core structural borrowings of shareholder-financed businesses

Notes

(i) Holding company includes centrally managed group holding companies.

(ii) As recorded in note C5.1 of the IFRS financial statements.

(iii) The movement in the value of core structural borrowings includes foreign exchange effects for pounds sterling denominated debts. The movement in the mark-to-market value adjustment can be analysed as follows:

6 Comparison of EEV basis shareholders' equity with IFRS basis shareholders' equity

Note

The half year 2021 policyholder liabilities (net of reinsurers' share) and unallocated surplus of with-profits funds exclude US operations' policyholder liabilities following its classification as held for distribution and write down to its estimated fair value at 30 June 2021 which is consistent with the fair value recognised on IFRS basis. The half year 2020 and full year 2020 policyholder liabilities (net of reinsurers' share) and unallocated surplus of with-profits funds included amounts relating to US operations.

7 Methodology and accounting presentation

The methodology and accounting presentation below are stated for the Group's continuing business operations only. Following its classification as discontinued operations, the Group's US operations are no longer included in covered business with comparatives being re-presented. Methodology applied for the discontinued US operations in the comparative results is provided in note 8 of the Group's EEV financial statements for the year ended 31 December 2020.

(i) Methodology

(a) Covered business

The EEV basis results for the Group's continuing operations are prepared for 'covered business' as defined by the EEV Principles. Covered business represents the Group's long-term insurance business (including the Group's investments in joint venture and associate insurance operations), for which the value of new and in-force contracts is attributable to shareholders. The definition of long-term insurance business comprises those contracts falling under the definition for regulatory purposes. Africa operations are included within the covered business from 2021 following the change in the Group's operating segments. Further details on the Group's segments are provided in note B1.3 of the IFRS basis results. The amounts are shown within the continuing insurance segment for all periods.

The EEV basis results for the Group's covered business are then combined with the post-tax IFRS basis results of the Group's asset management and other operations (including interest costs on core structural borrowings and corporate expenditure for head office functions in London and Hong Kong that is not recharged/allocated to the insurance operations), with an adjustment to deduct the unwind of expected margins on the internal management of the assets of the covered business. Under the EEV Principles, the results for covered business incorporate the projected margins of attaching internal asset management, as described in note (g) below.

(b) Valuation of in-force and new business

The EEV basis results are prepared incorporating best estimate assumptions about all relevant factors including levels of future investment returns, persistency, mortality, morbidity and expenses, as described in note 8(iii). These assumptions are used to project future cash flows. The present value of the projected future cash flows is then calculated using a discount rate, as shown in note 8(i), which reflects both the time value of money and all other non-diversifiable risks associated with the cash flows that are not otherwise allowed for.

The total profit that emerges over the lifetime of an individual contract as calculated under the EEV basis is the same as that calculated under the IFRS basis. Since the EEV basis reflects discounted future cash flows, under the EEV methodology the profit emergence is advanced, thus more closely aligning the timing of the recognition of profit with the efforts and risks of current management actions, particularly with regard to business sold during the period.

New business

In determining the EEV basis value of new business, premiums are included in projected cash flows on the same basis of distinguishing regular and single premium business as set out in the Group's new business sales reporting.

New business premiums reflect those premiums attaching to the covered business, including premiums for contracts classified as investment contracts under IFRS 4. New business premiums for regular premium products are shown on an annualised basis.

New business profit represents profit determined by applying operating and economic assumptions as at the end of the period. New business profitability is a key metric for the Group's management of the development of the business. In addition, new business margins are shown by reference to annual premium equivalent (APE) and the present value of new business premiums (PVNBP). These margins are calculated as the percentage of the value of new business profit to APE and PVNBP. APE is calculated as the aggregate of regular premiums on new business written in the period and one-tenth of single premiums. PVNBP is calculated as the aggregate of single premiums and the present value of expected future premiums from regular premium new business, allowing for lapses and the other assumptions made in determining the EEV new business profit.

Valuation movements on investments

Investment gains and losses during the period (to the extent that changes in capital values do not directly match changes in liabilities) are included directly in the profit or loss for the period and shareholders' equity as they arise.

The results for the covered business conceptually reflect the aggregate of the post-tax IFRS basis results and the movements in the additional shareholders' interest recognised on an EEV basis. Therefore, the starting point for the calculation of the EEV basis results reflects the market value movements recognised on an IFRS basis.

(c) Cost of capital

A charge is deducted from the embedded value for the cost of locked-in required capital supporting the Group's long-term business. The cost is the difference between the nominal value of the capital held and the discounted value of the projected releases of this capital, allowing for post-tax investment earnings on the capital.

The EEV results are affected by the movement in this cost from period to period, which comprises a charge against new business profit and generally a release in respect of the reduction in capital requirements for business in force as this runs off.

Where required capital is held within a with-profits long-term fund, the value placed on surplus assets within the fund is already adjusted to reflect its expected release over time and so no further adjustment to the shareholder position is necessary.

(d) Financial options and guarantees

Nature of financial options and guarantees

Participating products, principally written in Hong Kong, Singapore and Malaysia, have both guaranteed and non-guaranteed elements. These products provide returns to policyholders through bonuses that are smoothed. There are two types of bonuses: regular and final. Regular bonuses are declared once a year and, once credited, are guaranteed in accordance with the terms of the particular products. Final bonuses are guaranteed only until the next bonus declaration.

There are also various non-participating long-term products with guarantees. The principal guarantees are those for whole-of-life contracts with floor levels of policyholder benefits that typically accrue at rates set at inception and do not vary subsequently with market conditions. Similar to participating products, the policyholder charges incorporate an allowance for the cost of providing these guarantees, which, for certain whole-of-life products in Hong Kong, remains constant throughout varying economic conditions, rather than reducing as the economic environment improves and vice versa.

Time value

The value of financial options and guarantees comprises the intrinsic value (arising from a deterministic valuation on best estimate assumptions) and the time value (arising from the variability of economic outcomes in the future).

Where appropriate, a full stochastic valuation has been undertaken to determine the time value of financial options and guarantees. The economic assumptions used for the stochastic calculations are consistent with those used for the deterministic calculations. Assumptions specific to the stochastic calculations reflect local market conditions and are based on a combination of actual market data, historic market data and an assessment of long-term economic conditions. Common principles have been adopted across the Group for the stochastic asset models, such as separate modelling of individual asset classes with an allowance for correlations between various asset classes. Details of the key characteristics of each model are given in note 8(ii).

In deriving the time value of financial options and guarantees, management actions in response to emerging investment and fund solvency conditions have been modelled. Management actions encompass, but are not confined to, investment allocation decisions, levels of regular and final bonuses and credited rates. Bonus rates are projected from current levels and varied in accordance with assumed management actions applying in the emerging investment and fund solvency conditions. In all instances, the modelled actions are in accordance with approved local practice and therefore reflect the options available to management.

(e) Level of required capital

In adopting the EEV Principles, Prudential has based required capital on the applicable local statutory regulations, including any amounts considered to be required above the local statutory minimum requirements to satisfy regulatory constraints.

For shareholder-backed businesses, the level of required capital has been set to an amount at least equal to local statutory notification requirements:

- For China JV life operations, the level of required capital follows the approach for embedded value reporting issued by the China Association of Actuaries (CAA) reflecting the C-ROSS regime; and

- For Singapore life operations, from 31 March 2020 the level of net worth and required capital is based on the Tier 1 Capital position under the new risk-based capital framework (RBC2), which removes certain negative reserves permitted to be recognised in the full RBC2 regulatory position applicable to the Group's GWS capital position, in order to better reflect free surplus and its generation;

(f) With-profits business and the treatment of the estate

For the Group's relevant operations, the proportion of surplus allocated to shareholders from the with-profits funds has been based on the applicable profit distribution between shareholders and policyholders. The EEV methodology includes the value attributed to the shareholders' interest in the residual estate of the in-force with-profits business. In any scenarios where the total assets of the life fund are insufficient to meet policyholder claims in full, the excess cost is fully attributed to shareholders. As required, adjustments are also made to reflect any capital requirements for with-profits business in excess of the capital resources of the with-profits funds.

(g) Internal asset management

In line with the EEV Principles, the in-force and new business results from long-term business include the projected future profit or loss from asset management and service companies that support the Group's covered insurance businesses. The results of the Group's asset management operations include the current period profit from the management of both internal and external funds. EEV basis shareholders' other income and expenditure is adjusted to deduct the expected profit anticipated to arise in the current period in the opening VIF from internal asset management and other services. This deduction is on a basis consistent with that used for projecting the results for covered insurance business. Accordingly, Group operating profit includes the actual profit earned in respect of the management of these assets.

(h) Allowance for risk and risk discount rates

Overview

Under the EEV Principles, discount rates used to determine the present value of expected future cash flows are set by reference to risk-free rates plus a risk margin.

The risk-free rates are largely based on local government bond yields at the valuation date and are assumed to remain constant throughout the projection, with no trending or mean reversion to longer-term assumptions that cannot be observed in the current market.

The risk margin reflects any non-diversifiable risk associated with the emergence of distributable earnings that is not allowed for elsewhere in the valuation. In order to better reflect differences in relative market risk volatility inherent in each product group, Prudential sets the risk discount rates to reflect the expected volatility associated with the expected future shareholder cash flows for each product group in the embedded value model, rather than at a Group level.

Since financial options and guarantees are explicitly valued under the EEV methodology, risk discount rates exclude the effect of these product features.

The risk margin represents the aggregate of the allowance for market risk and allowance for non-diversifiable non-market risk. No allowance is required for non-market risks where these are assumed to be fully diversifiable.

Market risk allowance

The allowance for market risk represents the beta multiplied by the equity risk premium.

The beta of a portfolio or product measures its relative market risk. The risk discount rates reflect the market risk inherent in each product group and hence the volatility of product-specific cash flows. These are determined by considering how the profit from each product is affected by changes in expected returns across asset classes. By converting this into a relative rate of return, it is possible to derive a product-specific beta. This approach contrasts with a top-down approach to market risk where the risks associated with each product are not directly reflected in the valuation basis.

The Group's methodology allows for credit risk in determining the best estimate returns and through the market risk allowance, which covers expected long-term defaults, a credit risk premium (to reflect the volatility in downgrade and default levels) and short-term downgrades and defaults.

Allowance for non-diversifiable non-market risks

The majority of non-market and non-credit risks are considered to be diversifiable. An allowance for non-diversifiable non-market risks is estimated as set out below.

A base level allowance of 50 basis points is applied to cover the non-diversifiable non-market risks associated with the Group's covered business. For the Group's businesses in less mature markets (such as the Philippines, Thailand and Africa) additional allowances of 250 basis points are applied. The level and application of these allowances are reviewed and updated based on an assessment of the Group's exposure and experience in the markets. For the Group's business in more mature markets, no additional allowance is necessary. At 30 June 2021, the total allowance for non-diversifiable non-market risk is equivalent to a $(3.4) billion (or (8) per cent) reduction to the embedded value of continuing long-term business operations.

(i) Foreign currency translation

Foreign currency profits and losses have been translated at average exchange rates for the period. Foreign currency transactions are translated at the spot rate prevailing at the date of the transactions. Foreign currency assets and liabilities have been translated at closing exchange rates. The principal exchange rates are shown in note A1 of the Group IFRS financial statements.

(j) Taxation

In determining the post-tax profit for the period for covered business, the overall tax rate includes the impact of tax effects determined on a local regulatory basis. Tax payments and receipts included in the projected future cash flows to determine the value of in-force business are calculated using tax rates that have been announced and substantively enacted by the end of the reporting period.

(ii) Accounting presentation

(a) Analysis of post-tax profit

To the extent applicable, the presentation of the EEV basis profit or loss for the period from continuing operations is consistent with the classification between operating and non-operating results that the Group applies for the analysis of IFRS basis results. Operating results are determined as described in note (b) below and incorporate the following:

- New business profit, as defined in note (i)(b) above;

- Expected return on existing business, as described in note (c) below;

- The impact of routine changes of estimates relating to operating assumptions, as described in note (d) below; and

- Operating experience variances, as described in note (e) below.

In addition, operating results include the effect of changes in tax legislation, unless these changes are one-off and structural in nature, or primarily affect the level of projected investment returns, in which case they are reflected as a non-operating result.

Non-operating results comprise:

- Short-term fluctuations in investment returns;

- Mark-to-market value movements on core structural borrowings;

- Effect of changes in economic assumptions; and

- The impact of corporate transactions, if any, undertaken in the period.

Total profit or loss in the period attributable to shareholders and basic earnings per share include these items, together with actual investment returns. The Group believes that operating profit, as adjusted for these items, better reflects underlying performance.

(b) Investment returns included in operating profit

For the investment element of the assets covering the total net worth of long-term insurance business, investment returns are recognised in operating results at the expected long-term rates of return. These expected returns are calculated by reference to the asset mix of the portfolio.

(c) Expected return on existing business

Expected return on existing business comprises the expected unwind of discounting effects on the opening value of in-force business and required capital and the expected return on existing free surplus. The unwind of discount and the expected return on existing free surplus are determined after adjusting for the effect of changes in economic and operating assumptions in the current period on the embedded value at the beginning of the period, for example the unwind of discount on the value of in-force business and required capital is determined after adjusting both the opening value and the risk discount rates for the effect of changes in economic and operating assumptions in the current period.

(d) Effect of changes in operating assumptions

Operating profit includes the effect of changes to operating assumptions on the value of in-force business at the end of the reporting period. For presentational purposes the effect of changes is delineated to show the effect on the opening value of in-force business as operating assumption changes, with the experience variances subsequently being determined by reference to the assumptions at the end of the reporting period, as discussed below.

(e) Operating experience variances

Operating profit includes the effect of experience variances on operating assumptions, such as persistency, mortality, morbidity, expenses and other factors, which are calculated with reference to the assumptions at the end of the reporting period.

(f) Effect of changes in economic assumptions

Movements in the value of in-force business at the beginning of the period caused by changes in economic assumptions, net of the related changes in the time value of financial options and guarantees, are recorded in non-operating results.

8 Assumptions

(i) Principal economic assumptionsnote (a)

The EEV basis results for the Group's covered business are determined using economic assumptions where both the risk discount rates and long-term expected rates of return on investments are set with reference to risk-free rates of return at the end of the reporting period. Both the risk discount rate and expected rates of return are updated at each valuation date to reflect current market risk-free rates, with the effect that changes in market risk-free rates impact all projected future cash flows. The risk-free rates of return are largely based on local government bond yields and are assumed to remain constant throughout the projection, with no trending or mean reversion to longer-term assumptions that cannot be observed in the current market. The risk-free rates of return are shown below for each of the Group's insurance operations. Expected returns on equity and property assets and corporate bonds are derived by adding a risk premium to the risk-free rate based on the Group's long-term view.

As described in note 7(i)(h), risk discount rates are set equal to the risk-free rate at the valuation date plus allowances for market risk and non-diversifiable non-market risks appropriate to the features and risks of the underlying products and markets. Risks that are explicitly allowed for elsewhere in the EEV basis, such as via the cost of capital and the time value of options and guarantees, as set out in note 2(i), are not included in the risk discount rates.
