INDEPENDENT ASSURANCE STATEMENT

Scope and approach

Manila Water Company, Inc. commissioned DNV GL AS Philippines Branch (“DNV GL”) to undertake independent assurance of sustainability/non-financial disclosures disclosed in the 2017 Integrated Report (the “Report”) for the year ended 31 December 2017.

We performed our work using DNV GL’s assurance methodology VeriSustainTM1 , which is based on our professional experience, international assurance best practice including International Standard on Assurance Engagements 3000 (ISAE 3000) Revised* and the Global Reporting Initiative (GRI) Sustainability Reporting Guidelines.

We evaluated the performance data using the reliability principle together with Manila Water Company, Inc. data protocols for how the data are measured, recorded and reported. The performance data in the scope of assurance included economic, environmental and social data.

We understand that the reported financial data and information are based on data from Manila Water Company, Inc.’s Audited Financial Statements [posted March 1, 2018], which are subject to a separate independent audit process. The section on Financial Review was also excluded from the scope of assurance –as this was a summary of the 20-IS figure submitted to regulatory authorities (Philippines Stock Exchange – Securities and Exchange Commission).

We planned and performed our work to obtain the evidence we considered necessary to provide a basis for our assurance opinion. We are providing a ‘limited level’ of assurance based on DNV GL VeriSustain.

A multi-disciplinary team of sustainability and assurance specialists performed work at Manila Water Company, Inc. The boundary of assurance covered operations of Manila Water Company, Inc. in the Philippines, and operational activities in Vietnam, Myanmar and Indonesia.

Responsibilities of the Directors of Manila Water Company, Inc. and of the assurance providers

The Management of Manila Water Company, Inc. have sole responsibility for the preparation of the Report. In performing our assurance work, our responsibility is to the management of Manila Water Company, Inc.; however our statement represents our independent opinion about our assurance outcome to the readers of this Report.

We have no other contract with Manila Water Company, Inc. and this is the second year that we have provided assurance. DNV GL’s assurance engagements are based on the assumption that the data and information provided by the client to us as part of our review have been provided in good faith and free from misstatements.

Basis of our opinion

We undertook the following activities as part of the assurance process:

• Review of the current sustainability issues that could affect Manila Water Company, Inc. and are of interest to stakeholders;

• Review of Manila Water Company, Inc. approach to stakeholder engagement and recent outputs of a stakeholder engagement process conducted through a third party that included the vendors, government, parent companies and affiliates, and media and disaster respondents. Stakeholder engagement with employees and customers was carried out directly by Manila Water Company, Inc.;

• Review of information provided to us by Manila Water Company, Inc. on its reporting and management processes relating to GRI Sustainability Reporting Standards;

• DNV GL was free to choose personnel from various functions for the interview so as to ensure adequate coverage of the report. Functions interviewed included Human Resources, Enterprise Risk Management, Technical and Business Operations, Finance, Corporate Governance, and Sustainability;

• Site visits to Manila Water Company, Inc HQ, Marikina North Sewage Treatment Plant and Balara Filtration Plant for review of process and systems.

• Review of supporting evidence for key claims and data in the report. Our verification processes were prioritised according to materiality and we based our prioritisation on the materiality of issues at a consolidated corporate level.

The VeriSustain protocol is available upon request from DNV GL Website (www.dnvgl.com)

Limitations

Our assurance relies on the premise that the data and information provided by Manila Water Company, Inc. to us as part of our review procedures have been provided in good faith. Because of the selected nature (sampling) and other inherent limitation of both procedures and systems of internal control, there remains the unavoidable risk that errors or irregularities, possibly significant, may not have been detected. The engagement excludes the sustainability management, performance and reporting practices Manila Water Company, Inc.’s associated companies, suppliers, contractors and any third-parties mentioned in the Report, or any discrepancies between the Report and Manila Water Company, Inc’s website. The company position statements, the statements for the management approach, and case studies and examples are excluded from the scope of our work. We did not interview external stakeholders as part of this assurance engagement. The reported disclosures related to Economic performances are based on the financial disclosures and data, which were cross-checked with internal documents and the audited consolidated financial statements for transcription errors. Limited depth of evidence gathering including inquiry and analytical procedures and limited sampling at lower levels in the organization were applied as per agreed scope of engagement. The baseline data for Environmental and Social performance are verified with samples randomly taken by and the aggregated data at the corporate level are used for the verification. The procedures performed in a limited assurance engagement vary in nature and timing, and are less in extent than for a reasonable assurance engagement. Consequently, the level of assurance obtained in a limited assurance engagement is substantially lower than the assurance that would have been obtained if a reasonable assurance engagement had been performed. We expressly disclaims any liability or co-responsibility for any decision a person or an entity may make based on this Assurance Statement.
