Note 2: Statement of Accounting Policies
|
|
The principal accounting policies adopted in the preparation of these audited financial statements are set out below. These policies have been consistently applied to all the periods presented, unless otherwise stated.
2.1 Basis of Preparation
These audited financial statements have been prepared in accordance with New Zealand generally accepted accounting practice (NZGAAP). They comply with New Zealand equivalents to International Financial Reporting Standards (NZ IFRS), International Financial Reporting Standards (IFRS) and other applicable New Zealand Financial Reporting Standards, as appropriate for profit-oriented entities.
Entities reporting
The consolidated financial statements of the Group are for the economic entity comprising TrustPower Limited and its subsidiaries. The consolidated entity is designated as a profit-oriented entity for financial reporting purposes.
Statutory base
TrustPower Limited is registered under the Companies Act 1993 and is an issuer in terms of the Securities Act 1978. The financial statements have been prepared in accordance with the requirements of the Financial Reporting Act 1993 and the Companies Act 1993.
Application of NZ IFRS 1 First-time Adoption of New Zealand Equivalents to International Financial Reporting Standards
This is the first year the Group has prepared financial statements in accordance with NZ IFRS. NZ IFRS 1 First-time Adoption of New Zealand Equivalents to International Financial Reporting Standards has been applied in preparing these financial statements. Financial statements of the Group until 31 March 2007 had been prepared in accordance with previous New Zealand Financial Reporting Standards (NZ FRS). NZ FRS differ in certain respects from NZ IFRS. When preparing the Company and Group financial statements for the year ended 31 March 2007, the Group has amended certain accounting and valuation methods applied in the NZ FRS financial statements to comply with NZ IFRS. The comparative figures were restated to reflect these adjustments.
Reconciliations and descriptions of the effect of transition from previous NZ FRS to NZ IFRS on the Group’s and the Company’s equity and their net income are provided in note 35.
Historical cost convention
These financial statements have been prepared under the historical cost convention, as modified by the revaluation of generation assets and derivative financial instruments which are stated at fair value.
Estimates
The preparation of financial statements in conformity with NZ IFRS requires the Group to make judgements, estimates and assumptions that affect the application of policies and reported amounts of assets and liabilities, income and expenses. The areas involving a higher degree of judgment or complexity, or areas where assumptions and estimates are significant to the financial statements are disclosed in note 6.
Functional and Presentation Currency
The functional and reporting currency used in the preparation of these financial statements is New Zealand dollars, rounded to the nearest thousand.
2.2 Principles of Consolidation
Subsidiaries
Subsidiaries are all entities over which the Group has the power to govern the financial and operating policies generally accompanying a shareholding of more than one half of the voting rights. Subsidiaries are fully consolidated from the date on which control is transferred to the Group and they are no longer consolidated from the date that control ceases.
The purchase method of accounting is used to account for the acquisition of subsidiaries by the Group. The cost of an acquisition is measured as the fair values of the assets given, equity instruments issued and liabilities incurred or assumed at the date of exchange, plus costs directly attributable to the acquisition. Identifiable assets acquired and liabilities and contingent liabilities assumed in a business combination are measured initially at their fair values at the acquisition date, irrespective of the extent of any minority interest. The excess of the cost of the acquisition over the fair value of the Group’s share of the identifiable net assets acquired is recorded as goodwill. If the cost of the acquisition is less than the fair value of the net assets of the subsidiary acquired, the difference is recognised directly in the income statement.
Inter-company transactions, balances and unrealised gains on transactions between Group companies are eliminated. Unrealised losses are also eliminated but are considered as an impairment indicator of the assets transferred. Accounting policies of subsidiaries have been changed where necessary to ensure consistency with the policies adopted by the Group.
2.3 Segment Reporting
A business segment is a group of assets and operations engaged in providing products or services that are subject to risks and returns that are different from those of other business segments. A geographical segment is engaged in providing products or services within a particular economic environment that are subject to risks and returns that are different from those of segments operating in other economic environments.
2.4 Trade Receivables
Trade receivables are initially recognised at fair value and subsequently measured at amortised cost using the effective interest method, less provision for impairment. A provision for impairment of receivables is established when there is objective evidence that the Group will not be able to collect all amounts due according to the original terms of the receivables. The amount of the provision is the difference between the assets carrying amount and the present value of estimated future cash flows, discounted at the original effective interest rate. The amount of the impairment loss is recognised in the income statement.
2.5 Financial Assets
The Group classifies all of its investments as financial assets at fair value through the income statement, held to maturity financial assets or at cost. The classification depends on the purpose for which the investments were acquired. Management determines the classification of its investments at initial recognition.
Financial assets at fair value through the income statement
Financial assets at fair value through the income statement are financial assets held for trading. A financial asset is classified in this category if it is acquired principally for the purpose of selling in the short term. Derivatives are classified as held for trading unless they are designated as hedges. Assets in this category are classified as non-current assets where the remaining maturity of the asset is greater than 12 months; they are classified as current assets where the remaining maturity of the asset is less than 12 months.
Held to maturity financial assets
Held to maturity financial assets are stated at amortised cost less impairment losses.
Investments in subsidiaries
Investments in subsidiaries are recorded at cost less any impairment write-downs.
Loans and receivables
Loans and receivables are non-derivative financial assets with fixed or determinable payments that are not quoted in an active market. They are included in current assets, except for maturities greater than 12 months after the balance sheet date. These are classified as non-current assets. Advances to New Zealand based subsidiaries are interest free while advances to overseas based subsidiaries incur interest at a market rate.
Regular purchases and sales of financial assets are recognised on the trade-date – the date on which the Group commits to purchase or sell the asset. Investments are initially recognised at fair value plus transaction costs for all financial assets not carried at fair value through profit or loss. Financial assets carried at fair value through profit or loss are initially recognised at fair value, and transaction costs are expensed in the income statement. Financial assets are derecognised when the rights to receive cash flows from the investments have expired or have been transferred and the Group has transferred substantially all risks and rewards of ownership. Available-for-sale financial assets and financial assets at fair value through profit or loss are subsequently carried at fair value. Loans and receivables are carried at amortised cost using the effective interest method.
Gains or losses arising from changes in the fair value of the ‘financial assets at fair value through profit or loss’ category are presented in the income statement within fair value movements of financial instruments, in the period in which they arise. Dividend income from financial assets at fair value through profit or loss is recognised in the income statement as part of other income when the Group’s right to receive payments is established.
When securities classified as available-for-sale are sold or impaired, the accumulated fair value adjustments recognised in equity are included in the income statement as gains and losses from investment securities.
Interest on available-for-sale securities calculated using the effective interest method is recognised in the income statement as part of other income. Dividends on available-for-sale equity instruments are recognised in the income statement as part of other income when the Group’s right to receive payments is established.
The fair values of quoted investments are based on current bid prices. If the market for a financial asset is not active (and for unlisted securities), the Group establishes fair value by using valuation techniques. These include the use of recent arm’s length transactions, reference to other instruments that are substantially the same, discounted cash flow analysis and option pricing models, making maximum use of market inputs and relying as little as possible on entity-specific inputs.
The Group assesses at each balance sheet date whether there is objective evidence that a financial asset or a group of financial assets is impaired. In the case of equity securities classified as available-for-sale, a significant or prolonged decline in the fair value of the security below its cost is considered as an indicator that the securities are impaired. If any such evidence exists for available-for-sale financial assets, the cumulative loss (measured as the difference between the acquisition cost and the current fair value, less any impairment loss on that financial asset previously recognised in profit or loss) is removed from equity and recognised in the income statement. Impairment losses recognised in the income statement on equity instruments are not reversed through the income statement. Impairment testing of trade receivables is described in note 2.4.
2.6 Property, Plant and Equipment
Generation assets are shown at fair value, based on three-yearly valuations by independent external valuers, less subsequent depreciation. Any accumulated depreciation at the date of the revaluation is eliminated against the gross carrying amount of the asset, and the net amount is restated to the revalued amount of the asset. All other property is stated at historical cost less depreciation. Historical cost includes expenditure that is directly attributable to the acquisition of the items. Cost may also include transfers from equity of any gains/losses on qualifying cash flow hedges of foreign currency purchases of fixed assets.
The cost of assets constructed by the Group, including capital work in progress, includes the cost of all materials used in construction, direct labour specifically associated, resource management consent costs, and an appropriate proportion of variable and fixed overheads. Financing costs on uncompleted capital work in progress are capitalised at the specific project finance interest rate, where these meet certain time and monetary materiality limits. Costs cease to be capitalised as soon as the asset is ready for productive use and do not include any inefficiency costs.
Subsequent costs are included in the asset’s carrying amount or recognised as a separate asset only when it is probable that future economic benefits will flow to the Group and the cost of the item can be measured reliably. The carrying amount of any replaced item is derecognised. All other repairs and maintenance are charged to the income statement during the financial period in which they are incurred.
Increases in the carrying amount arising on revaluation of generation assets are credited to the revaluation reserve in shareholders’ equity. Decreases that offset previous increases of the same asset are charged against the revaluation reserve directly in equity. All other decreases are charged to the income statement.
Land is not depreciated. Depreciation on all other property, plant and equipment is calculated using the straight-line method at rates calculated to allocate each asset’s cost over its estimated useful life. Depreciation is charged on a straight line basis as follows:
| |
Freehold buildings 2% |
Generation assets 0.5%-5% |
| Metering equipment 5% |
Plant and equipment 10-33% |
The assets’ residual values and useful lives are reviewed, and adjusted if appropriate, at each balance date.
An asset’s carrying amount is written down immediately to its recoverable amount if the asset’s carrying amount is greater than its estimated recoverable amount.
Gains and losses on disposals are determined by comparing the proceeds with the carrying amount and are recognised within other fixed and investment asset charges/(credits), in the income statement. When revalued assets are sold, the amounts included in the revaluation reserve are transferred to retained earnings.
2.7 Emission Rights
The Group receives tradable emission rights from specific energy production levels of certain renewable generation facilities. The future revenue arising from the sale of these emission rights is a key matter in deciding whether to proceed with construction of the generation facility and is considered to be part of the value of the generation assets recorded in the balance sheet. Proceeds received on the sale of emission rights are recorded as deferred income in the balance sheet until the committed energy production level pertaining to the emission right sold has been generated.
Emission rights produced are recognised in the balance sheet if the right has been verified, it is probable that expected future economic benefits will flow to the Group, and the rights can be measured reliably. Emission rights are initially measured at cost. After initial recognition, the emission rights are carried at fair value with any changes taken to the income statement. Fair value is determined by reference to an active market. If the emission rights cannot be revalued because there is no active market, the emission rights are carried at cost less any subsequent accumulated impairment losses.
2.8 Intangible Assets
Customer base assets
Costs incurred in acquiring customers from other electricity supply companies and telecommunications companies are recorded as a customer base intangible asset. The customer bases are amortised on a straight line basis over the period of expected benefit. This period has been assessed as 20 years for electricity customer bases and 5 years for telecommunication customer bases. The carrying value of the customer bases is reviewed annually by the Directors and adjusted where it is considered necessary.
Computer software
Acquired computer software licences are capitalised on the basis of the costs incurred to acquire and bring to use the specific software. These costs are amortised over three years on a straight line basis.
Costs associated with developing or maintaining computer programmes are recognised as an expense as incurred. Costs that are directly associated with the development of identifiable and unique software products controlled by the Group, and that will probably generate economic benefits exceeding costs for more than one year, are recognised as intangible assets. Costs include the employee costs incurred as a result of developing software and an appropriate portion of relevant overheads. Computer software development costs recognised as assets are amortised over their estimated useful lives (not exceeding three years).
2.9 Revenue Recognition
Revenue comprises the fair value of consideration received or receivable for the sale of electricity, telecommunications and related services in the ordinary course of the Group’s activities. Revenue is shown net of goods and services tax, rebates and discounts and after eliminating sales within the Group.
Customer consumption of electricity is measured and billed by calendar month for half hourly metered customers and in line with meter reading schedules for non-half hourly metered customers. Accordingly revenues from electricity sales include an estimated accrual for units sold but not billed at balance date for non-half hourly metered customers.
Customer consumption of telecommunications services is measured and billed according to monthly billing cycles. Accordingly, revenues from telecommunications services provided include an estimated accrual for services provided but not billed at balance date.
Interest income is recognised on a time-proportion basis using the effective interest method.
Dividend income is recognised when the right to receive payment is established.
2.10 Employee Entitlements
Employee entitlements to salaries and wages, non monetary benefits, annual leave and other benefits are recognised when they accrue to employees. This includes the estimated liability for salaries and wages, annual leave and sick leave as a result of services rendered by employees up to balance date.
Share-based compensation
The Group operates an equity-settled, share-based compensation plan. The fair value of the employee services received in exchange for the granting of the options is recognised as an expense. The total amount to be expensed over the vesting period is determined by reference to the fair value of the options granted, excluding the impact of any non-market vesting conditions (for example, profitability and sales growth targets). Non-market vesting conditions are included in assumptions about the number of options that are expected to vest. At each balance sheet date, the entity revises its estimates of the number of options that are expected to vest. It recognises the impact of the revision to original estimates, if any, in the income statement, with a corresponding adjustment to equity.
The proceeds received net of any directly attributable transaction costs are credited to share capital when the options are exercised.
Bonus plans
The Group recognises a liability and an expense for bonuses, based on a formula that takes into consideration the profit attributable to the Company’s shareholders after certain adjustments. The Group recognises a provision where contractually obliged or where there is a past practice that has created a constructive obligation.
Termination benefits
Termination benefits are payable when employment is terminated by the Group before the normal retirement date, or whenever an employee accepts voluntary redundancy in exchange for these benefits. The Group recognises termination benefits when it is demonstrably committed to either: terminating the employment of current employees according to a detailed formal plan without possibility of withdrawal; or providing termination benefits as a result of an offer made to encourage voluntary redundancy. Benefits falling due more than 12 months after the balance sheet date are discounted to their present value.
2.11 Foreign Currencies
Items included in the financial statements of each of the Group’s entities are measured using the currency of the primary economic environment in which the entity operates (the functional currency). These financial statements are presented in New Zealand dollars, which is the Parent’s functional and presentation currency.
Transactions denominated in a foreign currency are converted to New Zealand dollars at the exchange rate on the date of the transaction. Monetary assets and liabilities arising from foreign currency transactions are translated at closing rates at balance date. Gains or losses from currency translation on these items are included in the income statement.
The results and financial position of all the group entities (none of which has the currency of a hyperinflationary economy) that have a functional currency different from the presentation currency are translated into the presentation currency as follows:
- assets and liabilities for each balance sheet presented are translated at the closing rate at balance date
- income and expenses for each income statement are translated at average exchange rates
- all resulting exchange rate differences are recognised as a separate component of equity.
On consolidation, foreign exchange differences arising from the translation of the net investment in foreign operations, and of borrowings and other currency instruments designated as hedges of such investments, are taken to the foreign currency translation reserve. When a foreign operation is partially disposed of or sold, such foreign exchange differences are recognised in the income statement as part of the gain or loss on sale.
2.12 Generation Development
The Group incurs costs in the exploration, evaluation, consenting and construction of generation assets. Costs incurred are expensed in the income statement unless such costs are highly likely to be recouped through successful development of, and generation of electricity from, a particular project. Where costs meet this criteria and are capitalised they will ultimately be amortised over the estimated useful life of a project once it is completed. The Directors review the status of capitalised development expenditure on a regular basis and in the event that a project is abandoned, or if the Directors consider the expenditure to be impaired, a write off or provision is made in the year in which that assessment is made.
2.13 Borrowings
Borrowings are recognised initially at fair value, net of transaction costs incurred. Borrowings are subsequently stated at amortised cost; any difference between the proceeds (net of transaction costs) and the redemption value is recognised in the income statement over the term of the borrowings using the effective interest method.
Borrowings are classified as current liabilities unless the Group has an unconditional right to defer settlement of the liability for at least 12 months after the balance sheet date.
2.14 Insurance
The Group has property, plant and equipment which is predominately concentrated at power station locations that has the potential to sustain major losses through damage to plant with resultant consequential costs.
To minimise the financial impact of such exposures, the major portion of the risk is insured by taking out appropriate insurance policies with appropriate counterparties. Any uninsured loss is recognised in the income statement at the time the loss is incurred.
2.15 Impairment of Non-financial Assets
Assets that have an indefinite useful life, for example land, are not subject to amortisation and are tested annually for impairment. Assets that are subject to amortisation are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount may not be recoverable. An impairment loss is recognised for the amount by which the asset’s carrying amount exceeds its recoverable amount.
The recoverable amount is the higher of an asset’s fair value less costs to sell and value in use. For the purposes of assessing impairment, assets are grouped at the lowest levels for which there are separately identifiable cash flows (cash-generating units). Assets other than goodwill that suffer an impairment are reviewed for possible reversal of the impairment at each balance date.
2.16 Cash and Cash Equivalents
Cash and cash equivalents include cash on hand, deposits held at call with banks, other short-term highly liquid investments with original maturities of three months or less, and bank overdrafts. Bank overdrafts are shown within borrowings in current liabilities in the balance sheet.
2.17 Cash Flow Statement
The following are the definitions used in the cash flow statement:
- cash is considered to be cash on hand and deposits held at call with banks, net of bank overdrafts
- operating activities include all activities that are not investing or financing activities
- investing activities are those activities relating to the acquisition, holding and disposal of fixed assets and investments
- financing activities are those activities, which result in changes in the size and composition of the capital structure of the Group. This includes both equity and debt not falling within the definition of cash. Dividends paid in relation to the capital structure are included in financing activities.
2.18 Goods and Services Tax (GST)
The income statement and cash flow statement have been prepared so that all components are stated exclusive of GST. All items in the balance sheet are stated exclusive of GST, with the exception of billed receivables and payables which include GST invoiced.
2.19 Income Tax
The income tax expense comprises both current and deferred tax. Income tax is recognised in the income statement except to the extent that it relates to items recognised directly in equity, in which case the income tax is recognised directly in equity.
Deferred income tax is provided in full, using the liability method, on temporary differences arising between the tax bases of assets and liabilities and their carrying amounts in the financial statements. The following temporary differences are not provided for: the initial recognition of assets or liabilities in a transaction other than a business combination that at the time of transaction affects neither accounting nor taxable profit, and differences relating to investments in subsidiaries to the extent that they will probably not reverse in the foreseeable future. Deferred tax is determined using tax rates (and laws) that have been enacted or substantially enacted by balance date and are expected to apply when the related deferred tax liability (asset) is settled (realised).
Deferred tax assets are recognised to the extent that it is probable that future taxable profit will be available against which the temporary differences can be utilised.
2.20 Derivative Financial Instruments and Hedging Activities
Derivatives are initially recognised at fair value on the date a derivative contract is entered into and are periodically remeasured at their fair value. The method of recognising the resulting gain or loss depends on whether the derivative is designated as a hedging instrument, and if so, the nature of the item being hedged. The Group designates certain derivatives as one of the following:
- hedges of the fair value of recognised assets or liabilities or a firm commitment (fair value hedge)
- hedges of highly probable forecast transactions (cash flow hedges)
- hedges of net investments in foreign operations.
The Group documents, at the inception of the transaction, the relationship between hedging instruments and hedged items, as well as its risk management objectives and strategy for undertaking various hedging transactions. The Group also documents its assessment, both at hedge inception and on an ongoing basis, of whether the derivatives that are used in hedging transactions are highly effective in offsetting changes in fair values or cash flows of hedged items. The fair values of various derivative instruments used for hedging purposes are disclosed in note 5. Movements on the hedging reserve in shareholders’ equity are shown in the statement of recognised income and expense. The full fair value of a derivative is classified as a non-current asset or liability when the remaining maturity of the derivative is more than 12 months; it is classified as a current asset or liability when the remaining maturity of the derivative is less than 12 months.
Fair Value Hedges
Changes in the fair value of derivatives that are designated and qualify as fair value hedges are recorded in the income statement, together with any changes in the fair value of the hedged asset or liability that are attributable to the hedged risk.
Cash Flow Hedges
The effective portion of changes in the fair value of derivatives that are designated and qualify as cash flow hedges are recognised in shareholders’ equity. The gain or loss relating to the ineffective portion is recognised immediately in the income statement.
Amounts accumulated in equity are recycled in the income statement in the periods when the hedged item affects profit or loss. However, when the forecast transaction that is hedged results in the recognition of a non-financial asset, the gains and losses previously deferred in shareholders’ equity are transferred from shareholders’ equity and included in the measurement of the cost of the asset.
When a hedging instrument expires or is sold, or when a hedge no longer meets the criteria for hedge accounting, any cumulative gain or loss existing in shareholders’ equity at that time remains in shareholders’ equity and is recognised in accordance with the above policy when the transaction occurs. When a forecast transaction is no longer expected to occur, the cumulative gain or loss that was reported in shareholders’ equity is immediately transferred to the income statement.
Net Investment Hedge
Hedges of net investments in foreign operations are accounted for similarly to cash flow hedges. Any gain or loss on the hedging instrument relating to the effective portion of the hedge is recognised in shareholders’ equity. The gain or loss relating to the ineffective portion is recognised immediately in the income statement.
Derivatives that do not qualify for hedge accounting
Certain derivatives do not qualify for hedge accounting. Changes in the fair value of these derivative instruments that do not qualify for hedge accounting are recognised immediately in the income statement.
2.21 Share Capital
Ordinary shares are classified as equity. Incremental costs directly attributable to the issue of new shares or options are shown in equity as a deduction, net of tax, from the proceeds.
2.22 Trade Payables
Trade payables are recognised initially at fair value and subsequently measured at amortised cost using the effective interest method.
2.23 Leases
Leases in which a significant portion of the risks and rewards of ownership are retained by the lessor are classified as operating leases. Payments made under operating leases (net of any incentives received from the lessor) are charged to the income statement on a straight-line basis over the period of the lease.
2.24 Dividend Distribution
Dividend distribution to the Company’s shareholders is recognised as a liability in the Group’s financial statements in the period in which the dividends are approved by the Board.
2.25 Adoption Status of Relevant New Financial Reporting Standards and Interpretations
The Group has elected not to early adopt the following standards which have been issued but are not yet effective:
- NZ IAS 23 Borrowing Costs – revisions approved July 2007 and effective for annual reporting periods beginning on or after 1 January 2009; and
- NZ IFRS 8 Operating Segments – approved December 2006 and effective for annual reporting periods beginning on or after 1 January 2009.
The adoption of these standards is not expected to have a material impact on the Group’s financial statements.

Note 3: Application of NZ IFRS 1
|
|
This is the first year the Group has prepared financial statements in accordance with NZ IFRS. These financial statements have been prepared as described in note 2.1. NZ IFRS 1 First-time Adoption of New Zealand Equivalents to International Financial Reporting Standards has been applied in preparing these financial statements. The Group’s NZ IFRS adoption date was 1 April 2006.
In preparing these financial statements in accordance with NZ IFRS 1 the Group has applied the applicable mandatory exemptions and certain of the optional exemptions from full retrospective application of NZ IFRS 1.
Optional exemptions applied:
-
Business combinations exemption
Business combinations that took place prior to the 1 April 2006 transition date have not been restated.
-
Deemed historical cost exemption
Net book value at 1 April 2006 has been taken to be deemed historical cost for certain generation assets.
Mandatory exemptions applied:
-
Hedge accounting exemption
The Group has applied hedge accounting from 1 April 2006 only if the hedge relationship meets all the hedge accounting criteria under NZ IAS 39.
-
Estimates exception
Estimates under NZ IFRS at 1 April 2006 are consistent with estimates made for the same date under previous GAAP.
Reconciliations and descriptions of the effect of transition from previous NZ FRS to NZ IFRS on the Group’s equity and its net income are provided in note 35.

Note 4: Segment Information
|
|
Primary Reporting Format - Business Segments
As at 31 March 2008, the Group is organised into two main business segments:
- development, ownership and operation of electricity generation facilities from renewable energy sources (“Generation”)
- retail sale of electricity to customers (“Retail”)
As the Generation segment derives substantially all of its revenue from internal transfers, it is not a separable reporting segment. Therefore, in accordance with the requirements of NZ IAS 14 Segment Reporting, there is only one reportable segment being Retail.
Secondary Reporting Format - Geographical Segments
The Group’s two business segments operate predominantly in New Zealand.

Financial Risk Management Objectives
TrustPower’s activities expose it to a variety of financial risks: electricity price risk, interest rate risk, exchange rate risk, credit risk and liquidity risk. The Group’s overall risk management programme focuses on the unpredictability of financial markets and seeks to minimise potential adverse effects on the Group’s financial performance. The Group uses derivative financial instruments to hedge certain risk exposures. Risk management is carried out under policies approved by the Board.

Electricity Price Risk
The Group is required to purchase a percentage of its electricity sold off the electricity spot market. This leaves the Group exposed to fluctuations in the spot price of electricity. The Group has entered into a number of electricity hedge contracts to reduce the commodity price risk from price fluctuations on the electricity spot market. These hedge contracts establish the price at which future specified quantities of electricity are purchased. Any resulting differential to be paid or received is recognised as a component of energy costs through the term of the contract. The Group has elected to apply cash flow hedge accounting to those instruments it deems material and which qualify as cash flow hedges while immaterial contracts are not hedge accounted.
The aggregate notional volume of the outstanding electricity derivatives at 31 March 2008 was 1,116GWh (31 March 2007: 1,224GWh).
The hedged anticipated electricity purchase transactions are expected to occur continuously throughout the next four years from balance sheet date consistent with the Group’s forecast electricity generation and retail electricity sales. Gains and losses recognised in the cash flow hedge reserve on electricity derivatives as of 31 March 2008 will be continuously released to the income statement in each period in which the underlying purchase transactions are recognised in the income statement.
Sensitivity analysis
The following tables summarise the impact of increases/decreases of the relevant forward electricity prices on the Group’s post-tax profit for the year and on other components of equity. The sensitivity analysis is based on the assumption that the relevant forward electricity prices had increased/decreased with all other variables held constant.

Interest Rate Risk
The Group’s bank borrowings are all on floating interest rates. The Group has various interest rate financial instruments to manage exposure to fluctuations in interest rates. Any resulting differential to be paid or received on the instruments is recognised as a component of interest paid. The Group has elected not to hedge account for these instruments.
The aggregate notional principal amounts of the outstanding interest rate derivative instruments at 31 March 2008 was $325,768,000 (31 March 2007: $95,000,000).
Interest payment transactions are expected to occur at various dates between one month and three years from the balance sheet date consistent with the Group’s forecast total borrowings.
Effective interest rates for the Parent and the Group are disclosed in note 25.
Sensitivity analysis
At 31 March 2008, if interest rates at that date had been 100 basis points higher/lower with all other variables held constant, post-tax profit for the year would have been adjusted by the amounts in the table below, mainly as a result of the fair value change in interest rate derivative instruments which are not hedge accounted. There would be no effect on other components of equity.

Exchange Rate Risk
The Group has entered into a number of forward exchange contracts to reduce the risk from price fluctuations of foreign currency costs associated with the construction of generation assets. Any resulting differential to be paid or received is recognised as a component of the cost of the project. The Group has elected to apply cash flow hedge accounting to these instruments.
The aggregate notional principal amounts of the outstanding forward foreign exchange contracts at 31 March 2008 was $38,014,000 (31 March 2007: $113,738,000).
The hedged anticipated transactions denominated in foreign currency are expected to occur at various dates between one month and five months from balance sheet date. Gains and losses recognised in the cash flow hedge reserve in equity on forward foreign exchange contracts as at 31 March 2008 will be recognised in the cost of any asset acquired when the cash flow from the anticipated underlying transactions occurs.
Sensitivity analysis
At 31 March 2008, if the New Zealand dollar had weakened/strengthened by 10 per cent against the currencies with which the Group has foreign currency risk, with all other variables held constant, post-tax profit for the year would not have been materially different.
Other components of equity would have been $2,485,000/$2,033,000 higher/lower (31 March 2007: $6,406,000/$5,241,000), arising from foreign exchange gains/losses on revaluation of foreign exchange contracts in a cash flow hedge relationship.
Credit Risk
The Group has no significant concentrations of credit risk (2007: none). It has policies in place to ensure that sales are made to customers with an appropriate credit history. Where a potential customer does not have a suitable credit history a bond is required before the customer is accepted. Derivative counterparties and cash transactions are limited to high credit quality financial institutions and other large electricity market participants. The Group has policies that limit the amount of credit exposure to any counterparty.
The carrying amounts of financial assets recognised in the balance sheet best represents the Group’s maximum exposure to credit risk at the reporting date without taking account of the value of any collateral obtained. As shown in note 19, the reported accounts receivable balance includes a provision for doubtful debts of $1,100,000 (2007: $1,100,000).
The Group has around 222,000 customers (2007: 220,000), only four (2007: three) of which make up more than one per cent of the Group’s total accounts receivable balance. The largest of these customers accounts for 19 per cent (2007: 10 per cent) of the Group’s total accounts receivable.
Liquidity Risk
The Group’s ability to readily attract cost effective funding is largely driven by its credit standing.
Prudent liquidity risk management implies maintaining sufficient cash and marketable securities, the availability of funding through adequate amount of committed credit facilities and the spreading of debt maturities.
Liquidity risk is monitored by continuously forecasting actual cash flows and matching the profiles of financial assets and liabilities.
Fair Values
Except for subordinated bonds (see note 26), the carrying amount of financial assets and financial liabilities recorded in the financial statements approximates their fair values.
Estimation of Fair Values
The fair values and net fair values of financial assets and financial liabilities are determined as follows:
- The fair value of financial assets and liabilities with standard terms and conditions and traded on active liquid markets are determined with reference to quoted market prices.
- The fair value of other financial assets and liabilities are calculated using market-quoted rates based on discounted cash flow analysis.
- The fair value of derivative financial instruments are calculated using quoted prices. Where such prices are not available, use is made of discounted cash flow analysis using the applicable yield curve or available forward price data for the duration of the instruments.
Where the fair value of a derivative is calculated as the present value of the estimated future cash flows of the instrument, the two key types of variables used by the valuation techniques are:
- forward price curve (for the relevant underlying interest rates, foreign exchange rates or commodity prices); and
- discount rates.
The selection of variables requires significant judgement and therefore there is a range of reasonably possible assumptions in respect of these variables that could be used in estimating the fair value of these derivatives. Maximum use is made of observable market data when selecting variables and developing assumptions for the valuation techniques.
Capital Risk Management Objectives
The Group’s objectives when managing capital are to safeguard the Group’s ability to continue as a going concern, so that it can continue to provide returns for shareholders and benefits for other stakeholders and to maintain an optimal capital structure to reduce the cost of capital.
In order to maintain or adjust the capital structure, the Group may adjust the amount of dividends paid to shareholders, return capital to shareholders, issue new shares or sell assets to reduce debt.
Consistent with others in the industry, the Group monitors capital on the basis of the gearing ratio. This ratio is calculated as net debt divided by total capital.
- Net debt is calculated as total borrowings less short term deposits. Total borrowings are calculated using a value of unsecured bank loans plus unsecured subordinated bonds.
- Total capital funding is calculated as total equity as shown in the balance sheet, adjusted for the fair value of financial instruments, plus net debt.
The gearing ratio is calculated below:

Note 6: Critical Accounting Estimates and Judgements
|
|
Estimates and judgements are frequently evaluated and are based on historical experience and other factors, including expectations of future events that are believed to be reasonable under the circumstances. The Group makes estimates and assumptions concerning the future. The resulting accounting estimates will, by definition, seldom equal the related actual results. The estimates and assumptions that have a significant risk of causing a material adjustment to the carrying amounts of assets and liabilities within the next financial year are discussed below.
Fair value of derivatives and other financial instruments
The fair value of financial instruments that are not traded in an active market (for example, electricity price hedges) is determined by using valuation techniques. The Group uses its judgement to select methods and make assumptions that are mainly based on market conditions existing at each balance date. The Group has used discounted cash flow analysis for various electricity price hedges that are not traded in an active market.
Electricity gross margin
Three key estimates are made when determining electricity gross margin. The accrual for all three factors is based on an estimate of unbilled units.
-
Revenue recognition
An accrual is estimated for units sold but not billed at balance date for non-half hourly metered customers. This estimate is based on units bought from the wholesale electricity market as well as historic factors. Significant judgement is required in making this determination.
-
Line cost recognition
Some electricity lines companies bill the Group based on the units and days that the Group has billed its customers. An accrual, similar to the revenue recognition accrual, is estimated for line charges incurred but not billed at balance date.
-
Energy cost recognition
An accrual is estimated for units that the Group believes it has consumed but has not yet been billed for by M-Co Limited, the Energy Clearing House. Significant judgement is required in making this determination.
Sensitivity analysis
If the estimated unbilled units had been 10% higher/lower, operating profit for the year would have (decreased)/increased by ($291,000)/$332,000 (2007:increased/(decreased) by $256,000/($251,000)).
Generation property, plant and equipment
The Group’s generation property, plant and equipment is stated at fair value as determined by an independent valuation undertaken on a three-yearly basis. The basis of the valuation is a discounted cash flow analysis of the future earnings of the assets. The major inputs that are used in the valuation model that require management judgement include sales volume forecasts, projected operational and capital expenditure profiles, capacity and life assumptions for each generation station.
Depreciation expense
A significant amount of management judgement is used when determining the useful lives of the Group’s generation assets for depreciation purposes. This is especially so for the Group’s longer lived assets.
Sensitivity analysis
If the estimated useful lives of generation assets was 10% higher/lower, operating profit for the year would have increased/decreased by $2,079,000/$2,542,000 (2007: $1,717,000/$2,098,000).
Amortisation expense
Managment judgement is used when determining the useful lives of the Group’s intangible assets for amortisation purposes.
Sensitivity analysis
If the estimated useful lives of intangible assets was 10% higher/lower, operating profit for the year would have increased/decreased by $458,000/$560,000 (2007: $384,000/$469,000).
Changes to accounting estimates
Following a detailed engineering review the total economic lives of some classes of assets were revised as follows:
Dams and major civil works - original life 100 years, revised life 200 years
Reinforced concrete structures - original life 50 years, revised life 100 years
Major generation plant - original life 50 years, revised life 100 years
The impact of this change has been to reduce the depreciation expense by $6,883,000. This impact will continue into future years.

Note 7: Earnings Per Share
|
|
Basic earnings per share is calculated by dividing the profit attributable to the shareholders of the company by the weighted average number of ordinary shares on issue during the year. Diluted earnings per share is calculated by adjusting the weighted average number of shares outstanding to assume conversion of all potential dilutive ordinary shares.

The Group has the following loan facilities with interest priced at between call and 180 day rates:
- $100,000,000 revolving loan expiring in one to two years
- $125,000,000 revolving loan expiring in two to five years
- $125,000,000 revolving loan expiring in over five years
- $106,948,000 table loan maturing in thirteen years
- AUD 160,000,000 revolving loan expiring in two to five years
All of the Group’s borrowings are unsecured. The Group borrows under a negative pledge arrangement with its bank loan providers, which with limited exceptions does not permit the Group to grant any security interest over its assets. The negative pledge deed requires the Group to maintain certain levels of shareholders’ funds and operate within defined performance and debt gearing ratios. The banking arrangements may also create restrictions over the sale or disposal of certain assets unless the bank loans are repaid or renegotiated, specifically:
- Facilities (i) to (iii) and (v) require a continuation of the existing business operations. There are no costs to cancel the facilities.
- Facility (iv) requires continued ownership by the Group of at least 30% in relation to Tararua Stage III wind generation assets with a book value of $162,737,000. There are no costs to cancel the facility.
Subsequent to balance date the Group has negotiated a further $100,000,000 of bank facilities expiring in two to five years.
A subsidiary company has entered into a fully defeased cross border lease in relation to generation assets with a book value of $65,500,000. The lease liability is not recognised in these financial statements as all obligations have been prepaid to the respective lessors. This creates restrictions on the disposal of the asset unless the subsidiary company holding the assets is part of the disposal. The lease expires in January 2018 and is subject to a potential termination payment, up to a maximum value of $5,415,000, in the event that the subsidiary wishes to terminate the lease.

The Verified Voluntary Emission Reductions above relate to completed generation production for the period 1 January 2004 to 31 December 2007.
Kyoto Carbon Credits
The Group has received 1,476,000 (2007:1,476,000) tonnes of carbon emission rights from the New Zealand Government in relation to completed or under construction generation facilities. This represents the maximum rights based upon specified levels of generation output from the new facilities for the period 1 January 2008 to 31 December 2012 and is reliant on the ongoing support of the Kyoto protocol and emission rights within the international community. The Group believes that it will be able to utilise 1,310,000 tonnes of these carbon emission rights. This potential revenue source is taken into consideration in the evaluation of generation development projects and in the valuation of the generation assets.
A contract has been signed with Electrabel, a European energy company, for the sale of 228,000 tonnes of carbon emission rights over five years from 2008-2012. This sale is dependent on the Group’s Tararua Wind Farm Stage II producing a minimum level of output. A contract has been signed with The Kansai Electric Power Company, a Japanese energy company, for the sale of 300,000 tonnes of carbon emission rights over five years from 2008-2012. This sale is dependent on the Group’s Tararua Wind Farm Stage III producing a minimum level of output.

Note 33: Employee Share Option Scheme
|
|
The Company has issued share options to certain employees. Each option issued under the Scheme converts to one ordinary share on exercise when employees are required to pay a non-refundable amount for the issue of the ordinary share (the exercise price). The options may be exercised any time after three years from issue date up until expiry, are non-transferable and conditional on the individual employee’s continued employment through this period. The exercise price is adjusted by an equity rate of return, dividends paid and capital structure changes from issue date up until the point at which the employee exercises the option.

Note 35: Explanation of Transition to New Zealand Equivalents to International Financial Reporting Standards
|
|
As described in Note 2.1, this is the first year financial statements have been prepared in accordance with NZ IFRS. The accounting policies set out in Note 2 have been applied in preparing the financial statements for the year ended 31 March 2008, the comparative information presented in these financial statements for the year ended 31 March 2007 and in the preparation of the opening NZ IFRS balance sheet at 1 April 2006 (the Group’s date of transition). In preparing its opening NZ IFRS balance sheet, comparative information for the year ended 31 March 2007, the Group has adjusted amounts reported previously in accordance with New Zealand Financial Reporting Standards (NZ FRS). An explanation of how the transition from NZ FRS has affected the Company’s and the Group’s equity and income statement is set out in the following tables and notes that accompany the tables.

A Deferred Tax Liability
Under NZ IFRS TrustPower is required to recognise a deferred tax liability in respect of all differences between the Group book values and the taxation authority book values with the exception of differences in relation to non depreciating assets. This “balance sheet” approach effectively creates an additional deferred tax liability on the revaluation amounts and other historic base differences of the generation assets. NZ FRS used a “profit and loss account” approach to deferred tax recognition where a partial recognition of these differences is made through assessing historic timing differences that have occurred.
B Derivative Financial Instruments
Under NZ IFRS derivative financial instrument contracts need to be valued and recognised “on balance sheet”. Resulting movements in the fair value of the financial instruments will be reported in the income statements each reporting period unless the Group can prove that a financial instrument qualifies for hedge accounting where it will be recorded as a movement in equity in the case of a cash flow hedge. NZ FRS allowed for note disclosure of quantities and values of financial instruments rather than recognition on the face of the primary financial statements.
As the financial instrument contracts of the Group are transacted to protect the Group’s risk position and not for speculative purposes, the majority of instruments qualify for hedge accounting.
C Provision for impairment of receivables
Under NZ IFRS provisions may only be recognised where it can be proved that an actual loss event has occurred. The effect of this is a reduction in the provision for impairment of receivables recognised under NZ IFRS compared with that recognised under NZ FRS.
D Intangible Assets
Under NZ IFRS computer software is considered an intangible asset, where as previously it was considered part of property, plant and equipment under NZ FRS. Consequently, depreciation relating to computer software is now considered to be amortisation and computer software is included in intangible assets.
E Share Option Reserve
Under NZ IFRS the fair value of share options granted to staff is recognised in equity. Under NZ FRS the fair value was recognised as a liability.
