Disclosure Template Guidelines for Information Entry These templates have been prepared for use by EDBs when making disclosures under subclauses 2.6.1(4), 2.6.1(5) and 2.6.5(5) of the Electricity Distribution Information Disclosure Determination 2012. Disclosures made under subclauses 2.6.1(4) and 2.6.1(5) must be made before the start of each disclosure year. Disclosures made under subclauses 2.6.5(5) must be made within 5 months after the start of the disclosure year. The information disclosed under 2.6.5(5) should be identical to that disclosed under 2.6.1(4) and 2.6.1(5). Under clause 2.6.3, EDBs can elect to complete and publicly disclose before the start of the disclosure year, an AMP update. EDBs can elect to complete and publicly disclose an AMP update instead of a full AMP in the following years: 31 March 2014 31 March 2015 If electing to complete an AMP update, EDBs can choose to not complete and disclose Schedule 13: Report on Asset Management Maturity Table. Schedule 13 sheet should be removed if not completed. If disclosing a Full AMP, EDBs must complete and disclose Schedule 13. and Dates To prepare the templates for disclosure, the supplier's company name should be entered in cell C8, the date of the first day of the 10 year planning period should be entered in cell C12, and the date on which the information is disclosed should be entered in cell C10 of the CoverSheet worksheet. The cell C12 entry (planning period start date) is used to calculate disclosure years in the column headings that show above some of the tables. It is also used to calculate the AMP planning period dates in the template title blocks (the title blocks are the light green shaded areas at the top of each template). The cell C8 entry (company name ) is used in the template title blocks. Dates should be entered in day/month/year order (Example "1 April 2013"). Data Entry Cells and Calculated Cells Data entered into this workbook may be entered only into the data entry cells. Data entry cells are the bordered, unshaded areas (white cells) in each template. Under no circumstances should data be entered into the workbook outside a data entry cell. In some cases, where the information for disclosure is able to be ascertained from disclosures elsewhere in the workbook, such information is disclosed in a calculated cell. Under no circumstances should the formulas in a calculated cell be overwritten. Validation Settings on Data Entry Cells To maintain a consistency of format and to guard against errors in data entry, some data entry cells test entries for validity and accept only a limited range of values. For example, entries may be limited to a list of category names or to values between 0% and 100%. Where this occurs, a validation message will appear when data is being entered. Conditional Formatting Settings on Data Entry Cells Schedule 12a columns G to K contains conditional formatting. The cells will change colour if the row totals do not add to 100%. Inserting Additional Rows The templates for schedules 11a, 12b and 12c may require additional rows to be inserted in tables marked 'include additional rows if needed'. Additional rows must not be inserted directly above the first row or below the last row of a table. This is to ensure that entries made in the new row are included in the totals. For schedule 12b the formula for column J (Utilisation of Installed Firm Capacity %) will need to be copied into the inserted row(s). Schedule 11a & 11b Schedule 11a requires Capital and Operational Expenditure to be expressed in both nominal and constant prices. The differences between the nominal and constant prices should reflect EDB expectations of the impact of changes in the costs of its labour, materials and other inputs (ie, inflationary pressures). Schedule 12b(ii) 3 NTL_LIBRARY-#286674-v1-Network_Tasman_AMP_Schedules_2015.XLSX Guidelines

The purpose of schedule 12b(ii) is to disclose transformer capacity as at the end of the current year. As the information may not be available in time for disclosures made under subclause 2.6.1(4), but available for disclosures made under 2.6.5(5), EDBs can choose not to disclose transformer capacity under schedule 12b(ii). EDBs who do not disclose transformer capacity under schedule 12b(ii) must disclose the information in schedule 9e(iii). Accordingly, the Excel template has been modified to allow the value "N/A" to be entered into these input cells. Schedule 12d Report Forecast Interruptions and Duration sub network disclosures If the supplier has sub networks, schedule 12d must be completed for the network and for each sub network. A copy of the schedule 12d worksheet must be made for each sub network. Schedule 13 Report on Asset Management Maturity The name of the standard applied (eg, 'PAS55') must be entered in cell K4. 4 NTL_LIBRARY-#286674-v1-Network_Tasman_AMP_Schedules_2015.XLSX Guidelines

SCHEDULE 11a: REPORT ON FORECAST CAPITAL EXPENDITURE sch ref This schedule requires a breakdown of forecast expenditure on assets for the current disclosure year and a 10 year planning period. The forecasts should be consistent with the supporting information set out in the AMP. The forecast is to be expressed in both constant price and nominal dollar terms. Also required is a forecast of the value of commissioned assets (i.e., the value of RAB additions) EDBs must provide explanatory comment on the difference between constant price and nominal dollar forecasts of expenditure on assets in Schedule 14a (Mandatory Explanatory Notes).

A key pre requisite of any robust policy is that the organisation's top must be seen to endorse and fully support it. Also vital to the effective implementation of the policy, is to tell the appropriate people of its content and their obligations under it. Where an organisation outsources some of its asset related activities, then these people and their organisations must equally be made aware of the policy's content. Also, there may be other stakeholders, such as regulatory authorities and shareholders who should be made aware of it. The organisation's asset policy, its organisational strategic plan, documents indicating how the asset policy was based upon the needs of the organisation and evidence of communication. 10 Asset strategy 11 Asset strategy What has the organisation done to ensure that its asset strategy is consistent with other appropriate organisational policies and strategies, and the needs of stakeholders? In what way does the organisation's asset strategy take account of the lifecycle of the assets, asset types and asset systems over which the organisation has stewardship? 3 The SCI and AMP have been There are feedback mechansisms from In setting an organisation's asset strategy, Top.

Generally, this will take into account the same polices, strategies and stakeholder requirements as covered in drafting the asset policy but at a greater level of detail. consultation. 3 Asset survey database, demonstrates how individual inspection items are used to prioritise work, and how aggregated data is used to identify patterns and trends. The network is disaggregated by asset type (verified by inspecting the 2014 AMP), and the lifecycle fo each asset type is considered. There is a comprehensive fault process that identifies trends and patterns of component failures. This is fed back into the condition replacement program. Good asset stewardship is the hallmark of an organisation compliant with widely used AM standards. A key component of this is the need to take account of the lifecycle of the assets, asset types and asset systems. (For example, this requirement is recognised in 4.3.1 d) of PAS 55). This question explores what an organisation has done to take lifecycle into account in its asset strategy. Top.

Regular reviews of the AM information system occur, and financial records are reviewed. An external contractor is available to customise Tech One. Other evidence is that Tasman has been able to respond to the Commission's s53zd notices.

This includes design, modification, procurement, construction and commissioning activities? 3 NTL's document control system has been inspected on previous occassions, and evidence of controls around key AM policies and practices has been cited. All standards, policies and procedures tend to be provided to the contractors by Tasman. Delta assist with drafting procedures and with acceptance testing of new assets. There is generally a high level of interaction and feedback between Tasman and Delta. Life cycle activities are about the implementation of asset plan(s) i.e. they are the "doing" phase. They need to be done effectively and well in order for asset to have any practical meaning. As a consequence, widely used standards (eg, PAS 55 s 4.5.1) require organisations to have in place appropriate process(es) and procedure(s) for the implementation of asset plan(s) and control of lifecycle activities. This question explores those aspects relevant to asset creation. Asset managers, design staff, construction staff and project managers from other impacted areas of the business, e.g. Procurement Documented process(es) and procedure(s) which are relevant to demonstrating the effective and control of life cycle activities during asset creation, acquisition, enhancement including design, modification, procurement, construction and commissioning. 91 Life Cycle Activities ensure that process(es) and/or procedure(s) for the implementation of asset plan(s) and control of activities during maintenance (and inspection) of assets are sufficient to ensure activities are carried out under specified conditions, are consistent with asset strategy and control cost, risk and performance? 3 Inspection of the asset survey database indicated that the number of defective assets identified is stable over time, indicating that assets risks are being well managed. The works contractor flags risks to Tasman as part of monthly meetings. There is a change process for major contractual parameters. Delta has a strong incentive to report risky assets. Having documented process(es) which ensure the asset plan(s) are implemented in accordance with any specified conditions, in a manner consistent with the asset policy, strategy and objectives and in such a way that cost, risk and asset system performance are appropriately controlled is critical. They are an essential part of turning intention into action (eg, as required by PAS 55 s 4.5.1).
