We called on this experience to successfully develop two small power stations in the Hawkes Bay — when others decided not to proceed. Esk Hydropower Project is named after the famous wine-growing valley, about 20km from the site. Two stations, Rimu and Toronui, will provide electricity for about 2,000 households. Rimu is the highest-head generation station in the North Island. TRUSTPOWER ANNUAL REPORT 2013 19

Shared Understanding In early 2012, as part of changes to our core customer care and billing system, TrustPower introduced a Business Intelligence Reporting system. The result is a system that seamlessly spans multiple aspects of our business. Here, focusing on our Metering & Field Services team, we explain why and how the new system was developed, and the shared benefits it brings. TRUSTPOWER ANNUAL REPORT 2013 21

These standards require that we comply with relevant ethical requirements and plan and perform the audit to obtain reasonable assurance about whether the financial statements are free from material misstatement. An audit involves performing procedures to obtain audit evidence about the amounts and disclosures in the financial statements. The procedures selected depend on the auditors’ judgement, including the assessment of the risks of material misstatement of the financial statements, whether due to fraud or error. In making those risk assessments, the auditors consider the internal controls relevant to the Company and the Group’s preparation of financial statements that give a true and fair view of the matters to which they relate, in order to design audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Company and the Group’s internal control. An audit also includes evaluating the appropriateness of accounting policies used and the reasonableness of accounting estimates, as well as evaluating the overall presentation of the financial statements. We believe that the audit evidence we have obtained is sufficient and appropriate to provide a basis for our audit opinion. We have no relationship with, or interests in, TrustPower Limited or any of its subsidiaries other than in our capacities as auditors, tax advisors and providers of other assurance services. These services have not impaired our independence as auditors of the Company and the Group. Opinion In our opinion, the financial statements on pages 39 to 75: (i) comply with generally accepted accounting practice in New Zealand; and (ii) comply with International Financial Reporting Standards; and (iii) give a true and fair view of the financial position of the Company and the Group as at 31 March 2013, and their financial performance and cash flows for the year then ended. Report on Other Legal and Regulatory Requirements We also report in accordance with Sections 16(1)(d) and 16(1)(e) of the Financial Reporting Act 1993. In relation to our audit of the financial statements for the year ended 31 March 2013: (i) we have obtained all the information and explanations that we have required; and (ii) in our opinion, proper accounting records have been kept by the Company as far as appears from an examination of those records. Restriction on Distribution or Use This report is made solely to the Company’s shareholders, as a body, in accordance with Section 205(1) of the Companies Act 1993. Our audit work has been undertaken so that we might state to the Company’s shareholders those matters which we are required to state to them in an auditors’ report and for no other purpose. To the fullest extent permitted by law, we do not accept or assume responsibility to anyone other than the Company and the Company’s shareholders, as a body, for our audit work, for this report or for the opinions we have formed.

The Group intends to adopt the new standard from 1 April 2013. NZ IFRS 9 Financial Instruments This standard addresses the classification, measurement and derecognition of financial assets and financial liabilities. NZ IFRS 9 was issued in November 2009 and October 2010. It replaces the parts of NZ IAS 39 that relate to the classification and measurement of financial instruments. NZ IFRS 9 requires financial assets to be classified into two measurement categories: those measured as at fair value and those measured at amortised cost. The determination is made at initial recognition. The classification depends on the entity’s business model for managing its financial instruments and contractual cash flow characteristics of the instrument. For financial liabilities, the standard retains most of NZ IAS 39 requirements. The main change is that in cases where the fair value option is taken for financial liabilities, the part of the fair value change due to an entity’s own credit risk is recorded in other comprehensive income rather than the income statement, unless this creates an accounting mismatch. The Group is yet to assess NZ IFRS 9’s full impact and intends to adopt NZ IFRS 9 no later than no later than 1 April 2015. TRUSTPOWER ANNUAL REPORT 2013 49

Note 5: Segment Information As at 31 March 2013, the Group is organised into two main business segments: • development, ownership and operation of electricity generation facilities from renewable energy sources including the trading of energy with Retail and external parties (“Generation”) • purchase of energy from Generation and retail sale of electricity to customers (“Retail”) The remaining activities of the Group are included in Other. This primarily relates to property services and some unallocated head office functions. The Board has further segregated Generation into New Zealand and Australian operations. Generation New Zealand includes the metering business which does not meet the criteria to be disclosed as a separate operating segment. Retail operates only in New Zealand and includes telecommunications operations which do not meet the criteria to be disclosed as a separate operating segment. The segment results for the year ended 31 March 2013 are as follows:

Inter-segment transactions are entered into under normal commercial terms and conditions that would also be available to unrelated third parties. The Board does not distinguish between revenue from internal or external customers when measuring the performance of segments. All revenue is reported to the Board on a basis consistent with that used in the income statement. The Board assesses the performance of segments based on a measure of adjusted EBITDAF. This measure excludes the effects of non-operational expenditure or gains such as loss/gain on disposal or impairments of property, plant and equipment, fair value changes in foreign currency financial assets/liabilities and costs of major business acquisitions. Interest income and expenditure and taxation costs are not allocated to segments as these activities are managed at a Group level by a central treasury function. The Board does not segregate assets and liabilities in assessing Group performance. Capital expenditure comprises additions to property, plant and equipment and intangible assets. A reconciliation of adjusted EBITDAF to profit before income tax is as follows:

Because of the contract terms, in particular that the volume of energy supplied is variable dependent on the actual generation of the Snowtown Wind Farm, the future minimum payments under the term of the contract, that expires on 31 December 2018, are contingent in nature and therefore not able to be quantified.

Interest rates paid during the year ranged from 2.9% to 6.2%. The Group has the following loan facilities with interest priced at between call and 180 day rates: (i) $100,000,000 revolving loan expiring in two to five years (ii) $75,000,000 revolving loan expiring in two to five years (iii) $67,338,000 table loan maturing in over five years (iv) $45,000,000 table loan maturing in over five years (v) AUD 180,000,000 revolving loan expiring in under one year (vi) AUD 194,800,000 revolving loan expiring in one to two years (vii) AUD 220,000,000 revolving loan expiring in one to two years Where drawn facilities mature within one year and the Group has an unconditional right to refinance the loans through undrawn facilities with the same lenders with maturity dates of greater than one year from the end of the reporting period, the loan is considered non-current. 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), (ii), (v), (vi) and (vii) require a continuation of the existing business operations. There are no costs to cancel the facilities. • Facility (iii) requires continued ownership by the Group of at least 30% in relation to Tararua Stage III wind generation assets with a book value of $148,806,000. There are no costs to cancel the facility. • Facility (vii) must be repaid if Snowtown South Wind Farm Pty Ltd is sold. Throughout the period the Group has complied with all debt covenant requirements as imposed by lenders (see above for requirements). Subsequent to balance date the Group has accepted offers to refinance the facility expiring in under one year and extend it by AUD 20,000,000 to AUD 200,000,000. This facility is currently being documented and will mature in two to five years. On 30 April 2013 the Group entered into an AUD 171,900,000 table loan maturing in over five years. 60

Note 35: Contingent Liabilities, Operating Leases, and Subsequent Events Inland Revenue is currently disputing the tax treatment adopted by the Group in relation to feasibility expenditure in the 2006, 2007 and 2008 financial years. Inland Revenue has now issued assessments for the 2006, 2007 and 2008 financial years. These assessments are based on the adjudication report previously issued by Inland Revenue and now allow a deduction for certain categories of expenditure which were previously disputed by Inland Revenue but contend that the costs of obtaining resource consents should have been capitalised. The assessments are based on Inland Revenue’s determination of what should be considered resource consent costs. The Group does not agree with the basis of the assessments. It continues to believe the tax treatment it has adopted is correct and continues to defend its position. The case is currently scheduled to be heard in the High Court in August 2013. Should Inland Revenue be completely successful in its claim for all three years, the resulting liability would give rise to an additional tax payment of $5,924,000 and interest expense of $2,838,000. Based on the principle of the assessments, the Group would need to revise its policy for capitalising the costs of resource consents for tax purposes in the 2009 and future years. This would give rise to a further estimated tax payment of $4,114,000 and interest expense of $1,104,000 in respect of the 2009 to 2013 years. This would primarily result in a balance sheet adjustment in the financial statements as most resource consents are depreciable intangible property. The impact of these adjustments on the tax expense in the income statement is difficult to estimate but is unlikely to exceed $3,300,000 for all years up to 2013. The Group is not aware of any other material contingent liabilities at balance date (2012: nil). Other than disclosed in note 6 the Group is not party to any material operating leases at balance date (2012: nil). The Group is not aware of any significant events occurring subsequent to balance date that have not been disclosed.

Note 36: Related Party Transactions Key management personnel The key management personnel compensation (including Directors’ fees) is as follows:

$910,000 of this amount was unpaid at 31 March 2013 (2012: $703,000). All key management personnel participate in a cash settled, share based incentive scheme. This scheme was introduced in 2007 and replaces the employee share option scheme (refer to note 37). Subsidiaries Advances have been made to/from subsidiaries (refer to note 21) and are payable on demand. These advances are not expected to be repaid in the coming year. Advances to New Zealand based subsidiaries are interest free while interest is charged to overseas based subsidiaries at a market rate. The net advances as disclosed in note 21 include the balances due to/from subsidiaries in respect of the following transactions. The Parent has a lease contract with its subsidiary Tararua Wind Power Limited for the use of the subsidiary company’s generation assets. The Parent had a similar lease contract with its former subsidiary Cobb Power Limited until Cobb Power Limited was amalgamated into the Parent on 31 March 2012 (see note 23). These commitments cannot be quantified because they are dependent on subsidiary asset valuations and capital expenditure. The Parent has an insurance contract with its subsidiary TrustPower Insurance Limited which is renewed annually. The impact of transactions with subsidiaries on the profit of the Parent and Group is shown below.

Except as noted above there are no amounts outstanding at 31 March 2013 (2012: nil).

Note 37: Employee Share Based Compensation 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 initial exercise price was set by taking the average closing market price of the shares during the ten business days up to and including the issue of the options. 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.

Members of the Parent’s executive management team and certain other employees (together defined as key management personnel) are eligible to receive payment under a cash settled share based payment scheme. The scheme is defined as follows: An incentive scheme for key management personnel of the Parent was implemented on 15 May 2009. This is a cash-settled share-based payment scheme covering a three-year period. Subsequently, each year on the 15th of May, a new tranche of the scheme has been issued and covers a period of three years from the issue date. Key management personnel are eligible to receive a bonus payment at the end of the three year period of the scheme, the sum of which is determined by the total return on a notional number of allocated shares. The return is calculated as the sum of dividends paid by the Parent plus the increase in share price over the period. Payment is only made if a minimum return, set by the Board, is met. Additionally the scheme has a set maximum return above which no increase in the bonus is received by the participants. The total return is calculated for a three year period commencing on the 15th of May with reference to the average share price over the ten days prior to the scheme closing. The fair value of the liability at 31 March 2013 has been determined by reference to the Parent’s current share price and expected dividends and share price movements with comparison to the share price at the start of the relevant period and adjusted to reflect the present value of these future expected cash flows. For the year ended 31 March 2013 the total expense recognised in the income statement was $89,000 (2012: $(43,000)) and the liability recognised in the statement of financial position as at 31 March 2013 is $99,000 (2012: $10,000).

Note 38: 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 the end of each reporting period. The Group has used discounted cash flow analysis for various electricity price hedges that are not traded in an active market. The forward curve is derived from a combination of market quoted prices and management’s best estimates. The discount rate is assumed as the counterparty’s cost of funds for the period of the instrument. See note 39 for sensitivity analysis. 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 the end of the reporting period for non-half hourly metered customers. This estimate is based on units bought from the wholesale electricity market as well as historical 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 while the remaining electricity lines companies bill the Group based on estimated total units and days. For the companies that base their bill on the Group’s customer billing, an accrual, similar to the revenue recognition accrual, is estimated for line charges incurred but not billed at the end of the reporting period. • Energy cost recognition An accrual is estimated for units that the Group believes it has consumed but has not yet been billed for by Energy Clearing House Limited. 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 $(54,000)/$54,000 (2012: increased/(decreased) by $695,000/$(695,000)). Generation property, plant and equipment The Group’s generation property, plant and equipment is stated at fair value as established by an independent valuation undertaken at least every three years. This valuation is reviewed annually and if it is considered that there has been a material change then a new independent valuation is undertaken. 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 the forward price path of electricity, sales volume forecasts, projected operational and capital expenditure profiles, discount rates and life assumptions for each generation station. The following table outlines the key assumptions used by Deloitte Corporate Finance in preparing the most recent valuation as at 31 March 2012. In all cases there is an element of judgement required. The table shows the range of reasonably possible alternative assumption values considered. The valuation is based on a combination of values that are generally in the midpoint of the range.

Assumption Low High Valuation Impact New Zealand Assets Forward electricity price path Decreasing in real terms from Decreasing in real terms from -/+ $98,000,000 $98/MWh to $85/MWh by 2015 $98/MWh to $85/MWh by 2015 then constant. then increasing to $95/MWh by 2020.

The valuation impact is calculated as the movement in the fair value as a result of the change in the assumption and keeping all other valuation inputs constant. 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 were 10% higher/lower, operating profit for the year would have increased/(decreased) by $5,278,000/$(6,451,000) (2012: $4,804,000/$(5,872,000)). Amortisation expense Management 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 were 10% higher/lower, operating profit for the year would have increased/decreased by $721,000/$(881,000) (2012: $478,000/$(584,000)). 66

Note 38: Continued Income tax expense The Group is subject to income taxes in New Zealand and Australia. Significant judgement is required in determining the provision for income taxes. There are many transactions and calculations for which the ultimate tax determination is uncertain. The Group recognises liabilities for anticipated tax audit issues based on estimates of whether additional taxes will be due. Where the final tax outcome of these matters is different from the amounts that were initially recorded, such differences will impact the current and deferred income tax assets and liabilities in the period in which such determination is made. Provision against advances to subsidiaries For subsidiaries involved in generation development, the Parent fully provides for advances made until such time as a viable project is identified and construction commences. This provision is the result of significant uncertainty that economic projects will be completed and that the advances will be recoverable. Changes to accounting estimates Apart from the change in metering asset useful lives (refer note 2.6), there have been no changes to accounting estimates in the year. Note 39: Financial Risk Management Financial Risk Management Objectives TrustPower’s activities expose it to a variety of financial risks: electricity price risk, interest rate risk, exchange rate risk, liquidity risk and credit 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. (a) Electricity Price Risk The Group typically sells more electricity at fixed prices than it generates. As a result 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 where it sells electricity at a fixed price. The Group operates under an energy trading policy which limits the exposure the Group may have in any future period. Future exposure is estimated based on expected fixed price sales and generation output. 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. This risk management strategy assumes that the electricity wholesale market that currently operates will continue to do so in the future. There is a possibility that future regulatory intervention may fundamentally alter the structure of the wholesale electricity market. The likelihood and potential impact of such a change is unquantifiable. However, such an occurrence would likely necessitate a change to the Group’s electricity price risk management policies and require a review of assets and liabilities held at fair value where electricity price is a key assumption in their value. The aggregate notional volume of the outstanding electricity derivatives at 31 March 2013 was 1,275GWh (31 March 2012: 639GWh). The hedged anticipated electricity purchase transactions are expected to occur continuously throughout the next three years from the end of the reporting period 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 2013 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 as a result of the fair value change in electricity price derivatives.

(b) Interest Rate Risk The Group’s bank borrowings are all on floating interest rates exposing it to the risk that rising interest rates will increase the Group’s interest expense and, hence, reduce its profitability. The Group operates under a treasury policy which prescribes the proportion of fixed interest rate cover the Group must hold in relation to its future borrowings. This proportion is calculated based on the actual fixed rate cover held and the forecast debt levels of the Group. 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 to hedge account only a limited number of these instruments. The aggregate notional principal amounts of the outstanding interest rate derivative instruments at 31 March 2013 was $877,803,000 (31 March 2012: $489,459,000). Interest payment transactions are expected to occur at various dates between one month and eight years from the end of the reporting period consistent with the Group’s forecast total borrowings. Weighted average interest rates for the Parent and the Group are disclosed in note 26. Sensitivity analysis At 31 March 2013, 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 and other components of equity would have been adjusted by the amounts in the table below, as a result of the fair value change in interest rate derivative instruments.

Increase/(decrease) to profit of a 100 basis point decrease in interest rates (19,873) (10,752) (5,790) (6,587) Increase/(decrease) to profit of a 100 basis point increase in interest rates 19,058 10,336 5,484 6,195 Increase/(decrease) to equity of a 100 basis point decrease in interest rates (20,168) (11,235) (6,085) (7,070) Increase/(decrease) to equity of a 100 basis point increase in interest rates 19,344 10,800 5,770 6,659 TRUSTPOWER ANNUAL REPORT 2013 67

Note 39: Continued c) Exchange Rate Risk During the course of business the Group may enter into contracts for the construction of generation assets and the sale of carbon credits to be settled in a foreign currency in the future. This exposes the Group to movements in foreign exchange rates. The Group operates under a treasury policy which requires all foreign currency transactions over certain limits to be 100% hedged. Compliance with this policy is measured by forecasting future foreign currency transactions and ensuring that the exchange rate has been fixed. The Group enters into forward exchange contracts to reduce the risk from price fluctuations of foreign currency costs associated with the construction of property, plant and equipment or income associated with the sale of carbon credits. Any resulting differential to be paid or received is recognised as a component of the cost of the project for the construction of generation assets and as a part of revenue for the sale of carbon credits. 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 2013 was $247,476,000 (31 March 2012: $11,076,000). The hedged anticipated transactions denominated in foreign currency are expected to occur at various dates between one month and one year from the end of the reporting period. Gains and losses recognised in the cash flow hedge reserve in equity on forward foreign exchange contracts as at 31 March 2013 will be recycled to revenue from the sale of carbon credits when the credits are sold or to cost of property, plant and equipment when the assets are purchased. Sensitivity analysis At 31 March 2013, if the functional currency of the entities holding the forward foreign exchange contracts 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 different. Other components of equity would have been $24,145,000/$(24,145,000) higher/(lower) (31 March 2012: $(768,000)/$768,000 (lower)/higher), arising from foreign exchange gains/losses on revaluation of foreign exchange contracts in a cash flow hedge relationship. (d) Credit Risk The Group has no significant concentrations of credit risk (2012: 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 with a minimum Standard & Poor’s long-term credit rating of A+ and other large electricity market participants (all have a Standard & Poor’s long-term credit rating of at least BBB). Where a potential counterparty does not meet these credit criteria the maximum level of credit exposure is set individually by the Board. The Group has policies that limit the amount of credit exposure to any counterparty. The carrying amounts of financial assets recognised in the statement of financial position best represents the Group’s maximum exposure to credit risk at the reporting date without taking account of the value of any collateral obtained. Collateral is customer bond deposits held as cash - refer to note 25. This collateral reduces the exposure to credit risk by its nominal amount. As shown in note 19, the reported accounts receivable balance includes a provision for doubtful debts of $1,700,000 (2012: $1,800,000). The Group has around 206,000 customers (2012: 209,000), only four (2012: four) of which make up more than one per cent of the Group’s total accounts receivable balance. The largest of these customers accounts for 4 per cent (2012: 4 per cent) of the Group’s total accounts receivable. Included in other accounts payable and accruals is $861,000 (2012: $1,349,000) of bonds collected from customers who do not meet certain credit criteria. As of 31 March 2013, trade receivables relating to the Group and the Parent of $3,955,000 (2012: $4,652,000) were past due but not impaired. The ageing analysis of these trade receivables is as follows:

Note 39: Continued (e) 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 an adequate amount of committed credit facilities and the spreading of debt maturities. The Group operates under a treasury policy which dictates the level of available committed facility to be maintained to provide cover for reasonably conceivable adverse conditions. This is measured by forecasting debt levels under various adverse scenarios and comparing this to committed facility levels. The treasury policy also requires a spread of debt maturities which is measured by the proportion of debt maturing in various time bands. The tables below analyse the Group’s and the Parent’s financial liabilities excluding gross settled derivative financial liabilities into relevant maturity groupings based on the remaining period to the earliest possible contractual maturity date at the period end date.

Fair Values Except for subordinated bonds and senior bonds (see notes 27 and 28), 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 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 discounted cash flow analysis based on market-quoted rates. • 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 (as described below); and • discount rates.

Valuation Input Source Interest rate forward price curve Published market swap rates Foreign exchange forward prices Published spot foreign exchange rates and interest rate differentials Electricity forward price curve Market quoted prices where available and management’s best estimate based on its view of the long run marginal cost of new generation where no market quoted prices are available. Discount rate for valuing interest rate derivatives Published market interest rates as applicable to the remaining life of the instrument. Discount rate for valuing forward foreign exchange contracts Published market interest rates as applicable to the remaining life of the instrument. Discount rate for valuing electricity price derivatives Assumed counterparty cost of funds ranging from 3.8% to 4.3% 70

Note 39: Continued 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. See earlier in this note for sensitivity analysis. NZ IFRS 7 requires that financial instruments are measured in the statement of financial position at fair value, this requires disclosure of fair value measurements by level of the following fair value measurement hierarchy: • Quoted prices (unadjusted) in active markets for identical assets or liabilities (level 1). • Inputs other than quoted prices included within level 1 that are observable for the asset or liability, either directly (that is, as prices) or indirectly (that is, derived from prices) (level 2). • Inputs for the asset or liability that are not based on observable market data (that is, unobservable inputs) (level 3). The following tables present the Group’s and Parent’s financial assets and liabilities that are measured at fair value. Group Level 1 Level 2 Level 3 Total 31 March 2013 $000 $000 $000 $000

Electricity price derivatives are classified as Level 3 because the assumed location factors which are used to adjust the forward price path are unobservable. A sensitivity analysis showing the effect on the value of the electricity price derivatives of reasonably possible alternative price path assumptions is shown in section (a) of this note. 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 and senior bonds. • Total capital funding is calculated as total equity as shown in the statement of financial position, adjusted for the fair value of financial instruments, plus net debt.

Voting Rights Every shareholder present in person, by proxy or by representative, on a vote by voices or a show of hands has one vote, and on a poll has one vote for each fully paid share held. Shares held as treasury stock do not have voting rights. Stock Exchange Listing The Company’s shares are listed on the NZSX and its senior and subordinated bonds are listed on the NZDX. Current Credit Rating Status TrustPower does not currently have an external credit rating. Current NZX Waivers NZX has granted a waiver dated 23 March 2006 from NZSX Listing Rule 8.1.7 (change of option exercise price or number of underlying securities) to enable the Company to issue options under the Company’s Executive Share Option Plan dated 28 February 2006 (as amended on 12 May 2006) in accordance with the exercise price formula contained in the Rules of the Plan. That exercise price formula permits the exercise price to be recalculated on a daily basis which may not be permitted by Listing Rule 8.1.7. The waiver has been granted on the condition that options outstanding issued under the Plan do not exceed 1% of the total shares of the Company. This waiver was varied on 6 July 2006 to permit TrustPower to vary the exercise price of Options issued on 29 May 2006 by amending the formula to permit the dividend with a record date of 26 May 2006 to be included in the calculation of the exercise price, notwithstanding that the record date of such dividends was prior to the issue date of the Options. The waiver described above is no longer required or relied upon as the last options issued in reliance on the waiver lapsed in June 2012.
