3.2 Summary of major accounting policies

Reinsurance contracts: in March 2004 the IASB published IFRS 4 "Insurance Contracts". The first standard governing the accounting of insurance contracts, it divides the "Insurance Contracts" project into two phases. IFRS 4 represents the outcome of Phase I and serves as a transitional arrangement until the IASB defines the measurement of insurance contracts after completion of Phase II. Underwriting business is to be subdivided into insurance or so-called "investment contracts". Contracts with a significant insurance risk are considered to be insurance contracts, while contracts without significant insurance risk are to be classified as investment contracts. The standard is also applicable to reinsurance contracts. IFRS 4 contains fundamental rules governing specific circumstances, such as the separation of embedded derivatives and unbundling of deposit components. In conformity with these basic rules of IFRS 4 and the IFRS Framework, Hannover Re is availing itself of the option of retaining the previously used accounting policies for underwriting items (US GAAP).

Financial assets: as a basic principle we recognise the purchase and sale of directly held financial assets including derivative financial instruments as at the settlement date.

Financial assets held to maturity are comprised of non-derivative assets that entail fixed or determinable payments on a defined due date and are acquired with the intent and ability to be held until maturity. They are measured at amortised cost. Payment of the corresponding premiums or discounts is spread across the duration of the instruments in the statement of income using the effective interest rate method. Depreciation is taken in the event of permanent impairment. Please refer to our comments on impairments in this section.

Loans and receivables are non-derivative financial instruments that entail fixed or determinable payments on a defined due date and are not listed on an active market or sold at short notice. They are carried at amortised cost; premiums or discounts are deducted or added within the statement of income using the effective interest rate method until the amount repayable becomes due. Depreciation is taken only to the extent that repayment of a loan is unlikely or no longer expected in the full amount. Please refer to our comments on impairments in this section.

Financial assets at fair value through profit or loss consist of securities held for trading and those classified as measured at fair value through profit or loss since acquisition. This refers principally to unsecured debt instruments issued by corporate issuers and derivative financial instruments. Within the scope of the fair value option provided under IAS 39, according to which financial assets may be carried at fair value on first-time recognition subject to certain conditions, all structured securities that would have needed to have been broken down had they been recognised as available for sale or under loans and receivables are also recognised here. Hannover Re makes use of the fair value option solely for selected subportfolios of its assets. In addition, derivative financial instruments that Hannover Re does not recognise as a valuation unit with underlying risks are recognised here. Securities held for trading and securities classified as measured at fair value through profit or loss since acquisition are carried at their fair value on the balance sheet date. If stock market prices are not available for use as fair values, the carrying values are determined using generally acknowledged measurement methods. All unrealised gains or losses from this valuation are recognised in net investment income. The classification of financial assets at fair value through profit or loss is compatible with Hannover Re's risk management strategy and investment strategy, which is oriented extensively towards economic fair value variables.

Establishment of the fair value of financial instruments carried as assets or liabilities: the fair value of a financial instrument corresponds to the amount that Hannover Re would receive or pay if it were to sell or settle the said financial instrument on the balance sheet date. Insofar as market prices are listed on markets for financial instruments, these prices are used. In other cases the fair values are established on the basis of the market conditions prevailing on the balance sheet date. These fair values are calculated using recognised models of mathematical finance. Hannover Re uses a number of different valuation models, the details of which are set out in the following table.

Valuation models

Financial assets classified as available for sale are carried at fair value; accrued interest is recognised in this context. We allocate to this category those financial instruments that do not satisfy the criteria for classification as held to maturity, loans and receivables, at fair value through profit or loss, or trading. Unrealised gains and losses arising out of changes in the fair value of securities held as available for sale are recognised – with the exception of currency valuation differences on monetary items – directly in shareholder's equity after deduction of deferred taxes.

The fair value of fixed-income and variable-yield securities is determined primarily by means of prices fixed on publicly quoting markets or exchanges on the basis of "bid" prices. If such financial assets are not quoted on public markets, the fair value is calculated on the basis of the acknowledged effective interest rate method or estimated using other financial assets with similar credit rating, duration and return characteristics. Under the effective interest rate method the current market interest rate levels in the relevant fixed-interest-rate periods are always taken as a basis. The fair value of equities and equity-like financial assets is also calculated primarily on the basis of prices fixed on publicly quoting markets and exchanges.

Impairments: As at each balance sheet date we review our financial assets with an eye to objective, substantial indications of impairment. Permanent impairments on all fixed-income and variable-yield securities are recognised directly in the statement of income. In this context we take as a basis the same indicators as those discussed below for securities with the character of equity. Qualitative case-by-case analysis is also carried out. IAS 39.59 contains a list of objective, substantial indications for impairments of financial assets. In the case of fixed-income securities and loans reference is made, in particular, to the rating of the instrument, the rating of the issuer/borrower as well as the individual market assessment in order to establish whether they are impaired. When held-to-maturity instruments measured at amortised cost as well as loans and receivables are tested for impairment, we examine whether material items – looked at on their own – are impaired. The amount of the probable loss is arrived at from the difference between the book value of the asset and the present value of the expected future earnings flows. The book value is reduced directly by this amount and recognised as an expense. With the exception of value adjustments taken on accounts receivable, we recognize impairments directly on the assets side – without using an adjustment account – separately from the relevant items. If the reasons for the write-down cease to apply, a write-up is made in income up to at most the original amortised cost for fixed-income securities.

With respect to impairments on securities with the character of equity, IAS 39.61 (rev. 2003) states, in addition to the aforementioned principles, that a significant or prolonged decrease in fair value below acquisition cost constitutes objective evidence of impairment. Hannover Re considers securities to be impaired under IAS 39 if their fair value falls significantly, i.e. by at least 20%, or for a prolonged period, i.e. at least nine months, below acquisition cost. In accordance with IAS 39.69 the reversal of impairment losses on equities to the statement of income once impairment has been taken is prohibited, as is adjustment of the cost basis. Impairment is tested in each reporting period using the criteria defined by Hannover Re. If a security is considered to be impaired on the basis of these criteria, IAS 39.68 requires that a value adjustment be recognised in the amount of the fair value less historical cost and less prior value adjustments, meaning that depreciation is taken on the fair value as at the closing date – if available, on the publicly quoted stock exchange price.

Netting of financial instruments: financial assets and liabilities were only netted and recognised in the appropriate net amount where expressly permitted in law (reciprocity; similarity and maturity), in other words if the intention is to offset such items on a net basis and this offsetting can be effected simultaneously.

Other invested assets are for the most part recognised at nominal value. Insofar as such financial assets are not listed on public markets (e.g. participating interests in private equity firms), they are carried at the latest available "net asset value" as an approximation of the fair value.

Investments in associated companies are valued at equity on the basis of the proportionate shareholders' equity attributable to the Group. Under IAS 28.23, which requires the application of the equity method based on the investor's share of the results of operations of the investee, the goodwill apportionable to the associated companies must be recognised together with the investments in associated companies. The year-end result of an associated company relating to the Group's share is included in the net investment income and shown separately. As a general rule, the shareholders' equity and year-end result are taken from the associated company's latest available annual financial statement.

Real estate used by third parties (investment property) is valued at cost less scheduled depreciation and impairment. Straight-line depreciation is taken over the expected useful life – at most 50 years. Under the impairment test the market value of real estate for third-party use (recoverable amount) is determined using acknowledged valuation methods and compared with the carrying value; unscheduled depreciation is taken where necessary. Maintenance costs and repairs are expensed. Value-enhancing expenditures are capitalised if they extend the useful life.

Cash is carried at face value.

Funds held are receivables due to reinsurers from their clients in the amount of their contractually withheld cash deposits; they are recognised at acquisition cost (nominal amount). Appropriate allowance is made for credit risks.

Accounts receivable: the accounts receivable under reinsurance business and the other receivables are carried at nominal value; value adjustments are made where necessary on the basis of a case-by-case analysis. We use adjustment accounts for value adjustments taken on reinsurance accounts receivable, while all other write-downs are booked directly against the underlying position.

Deferred acquisition costs principally consist of commissions and other variable costs directly connected with the acquisition or renewal of existing reinsurance contracts. These acquisition costs are capitalised and amortised over the expected period of the underlying reinsurance contracts. Deferred acquisition costs are regularly tested for impairment.

Reinsurance recoverables on technical reserves: shares of our retrocessionaires in the technical reserves are calculated according to the contractual conditions on the basis of the gross technical reserves. Appropriate allowance is made for credit risks.

Intangible assets: in accordance with IFRS 3 "Business Combinations" scheduled depreciation is not taken on goodwill; instead, unscheduled depreciation is taken where necessary after an annual impairment test. For the purposes of the impairment test, goodwill is to be allocated pursuant to IAS 36 "Impairment of Assets" to so-called "cash generating units" (CGUs). Each CGU to which goodwill is allocated should represent the lowest level on which goodwill is monitored for internal management purposes and may not be larger than a primary or secondary segment. Following allocation of the goodwill it is necessary to determine for each CGU the recoverable amount, defined as the higher of the value in use and the fair value less costs to sell. The recoverable amount is to be compared with the book value of the CGU including goodwill. When the latter exceeds the recoverable amount, an impairment expense is to be recognised. The other intangible assets largely consist of purchased and self-developed software. This is recognised at acquisition cost less scheduled depreciation. The other intangible assets also contain – within the scope of corporate acquisitions – the expected present value of future profits (PVFP) at the time of acquisition of already existing life reinsurance portfolios; amortisation is taken according to the periods of the underlying acquired contracts. Intangible assets are regularly tested for impairment and unscheduled depreciation is taken where necessary.

Deferred tax assets: IAS 12 requires that assets-side deferred taxes be established if assets had to be recognised in a lower amount or liabilities in a higher amount in the consolidated balance sheet than in the tax balance sheet and if these differences will be cancelled out again for tax purposes in the future (so-called temporary differences). Deferred tax assets are also to be recognised on tax loss carry-forwards. Insofar as unrealised losses on securities are carried directly in shareholders' equity (cf. explanatory notes on financial assets held as available for sale), the resulting deferred tax assets are also recognised outside the statement of income. Valuation allowances are made for deferred tax assets as soon as realisation of the receivable no longer appears likely.

Other assets are accounted for at amortised cost.

Own-use real estate is measured in the same way as investment property.

Technical reserves: the technical reserves are shown for gross account in the balance sheet, i.e. before deduction of the share attributable to our reinsurers; cf. here the remarks concerning the corresponding assets. The reinsurers' portion is calculated and accounted for on the basis of the individual reinsurance contracts.

Loss and loss adjustment expense reserves are constituted for payment obligations from reinsurance losses that have occurred but have not yet been settled. They are subdivided into reserves for reinsurance losses reported by the balance sheet date and reserves for reinsurance losses that have already been incurred but not yet reported (IBNR) by the balance sheet date. The loss and loss adjustment expense reserves are based on estimates that may diverge from the actual amounts payable. In reinsurance business a considerable period of time may elapse between the occurrence of an insured loss, notification by the insurer and pro-rata payment of the loss by the reinsurer. For this reason the best estimate of the future settlement amount is carried. With the aid of actuarial methods, the estimate makes allowance for past experience and assumptions relating to the future development. With the exception of a few reserves, future payment obligations are not discounted.

Benefit reserves are comprised of the underwriting reserves for guaranteed claims of ceding companies in life and health reinsurance. Benefit reserves are determined using actuarial methods on the basis of the present value of future payments to cedants less the present value of premium still payable by cedants. The calculation includes assumptions relating to mortality, disability, lapse rates and the future interest rate development. The actuarial bases used in this context allow an adequate safety margin for the risks of change, error and random fluctuation. They correspond to those used in the premium calculation and are adjusted if the original safety margins no longer appear to be sufficient.

Unearned premium is premium that has already been collected but is allocated to future risk periods. In reinsurance business flat rates are sometimes used if the data required for calculation pro rata temporis is not available.

Deferred tax liabilities: in accordance with IAS 12 deferred tax liabilities must be accounted for if assets are to be recognised in a higher amount or liabilities in a lower amount in the consolidated balance sheet than in the tax balance sheet and if these differences will be cancelled out again in the future for tax purposes (so-called temporary differences).

Long-term liabilities principally consist of subordinated debts that can only be satisfied after the claims of other creditors in the event of liquidation or bankruptcy. They are measured at amortised cost. Liabilities to holders of minority shares in partnerships arising out of long-term capital commitments are measured at the fair value of the redemption amount as at the balance sheet date.

Financial liabilities at fair value through profit or loss: Hannover Re does not make use of the fair value option provided by IAS 39 to classify financial liabilities in this category upon first-time recognition.

Shareholders' equity: the items "common shares" and "additional paid-in capital" are comprised of the amounts paid in by the parent company's shareholders on its shares. In addition to the statutory reserves of the parent company and the allocations from net income, the retained earnings consist of reinvested profits generated by the Hannover Re Group companies in previous periods. What is more, in the event of a retrospective change of accounting policies, the adjustment for previous periods is recognised in the opening balance sheet value of the retained earnings and comparable items of the earliest reported period. Unrealised gains and losses from the fair value measurement of financial instruments held as available for sale are carried in cumulative other comprehensive income under unrealised price gains/losses from investments. Translation differences resulting from the currency translation of separate financial statements of foreign subsidiaries are recognised under gains and losses from currency translation.

Minority interests are shares in the equity of affiliated companies not held by companies belonging to the Group. IAS 1 "Presentation of Financial Statements" requires that minority interests be recognised separately within Group shareholders' equity. The minority interest in profit or loss is shown separately as profit appropriation following the net income ("thereof" note). This item refers mainly to minority interests in E+S Rück and its subsidiaries.

Disclosures about financial instruments: IFRS 7 "Financial Instruments: Disclosures" requires more extensive disclosures according to classes of financial instruments. In this context, the term "class" refers to the classification of financial instruments according to their risk characteristics. A minimum distinction between measurement at amortised cost or at fair value through profit or loss is required here. A more extensive or divergent distinction should, however, be geared to the purpose of the corresponding disclosures in the notes. In contrast, the term "category" is used within the meaning of the measurement categories defined in IAS 39 (held to maturity, loans and receivables, available for sale and financial assets at fair value through profit or loss with the subcategories of trading and designated financial instruments). Essentially, the following classes of financial instruments were established:

• Fixed-income securities
• Equities, equity funds and other variable-yield securities
• Short-term investments
• Other invested assets
• Other financial assets – at fair value through profit or loss
• Funds held and contract deposits (assets)
• Accounts receivable
• Other receivables
• Funds held and contract deposits (liabilities)
• Other liabilities
• Long-term debt
• Subordinated debt
• Other long-term liabilities

This grouping into classes was not, however, solely determinative for the type and structure of each disclosure in the notes. Rather, guided by the underlying business model of reinsurance, the disclosures were made on the basis of the facts and circumstances existing in the financial year and in light of the principle of materiality.
