Basis for our opinion

We conducted our audit in accordance with Dutch law, including the Dutch Standards on Auditing. Our responsibilities under those standards are further described in the 'Our responsibilities for the audit of the financial statements' section of our report.

We are independent of Bouwinvest Dutch Institutional Office Fund N.V. in accordance with the Wet toezicht accountantsorganisaties (Wta, Audit firms supervision act), the Verordening inzake de onafhankelijkheid van accountants bij assurance-opdrachten (ViO, Code of Ethics for Professional Accountants, a regulation with respect to independence) and other relevant independence regulations in The Netherlands. Furthermore, we have complied with the Verordening gedrags- en beroepsregels accountants (VGBA, Dutch Code of Ethics).

We believe the audit evidence we have obtained is sufficient and appropriate to provide a basis for our opinion.

Information in support of our opinion

We designed our audit procedures in the context of our audit of the financial statements as a whole and in forming our opinion thereon. The following information in support of our opinion was addressed in this context, and we do not provide a separate opinion or conclusion on these matters.

Materiality

Based on our professional judgement we determined the materiality for the financial statements as a whole at € 12 million. The materiality is based on 1% of total investment property. We have also taken into account misstatements and/or possible misstatements that in our opinion are material for the users of the financial statements for qualitative reasons.

Materiality overview
Materiality level	€ 12 million
Basis for materiality level	1% of total investment property
Threshold for reporting misstatements	€ 600 thousand

We agreed with Management Board that misstatements in excess of € 600 thousand, which are identified during the audit, would be reported to them, as well as smaller misstatements that in our view must be reported on qualitative grounds.

Scope of the group audit

Bouwinvest Dutch Institutional Office Fund N.V. is at the head of a group of entities. The financial information of this group is included in the consolidated financial statements of Bouwinvest Dutch Institutional Office Fund N.V.

Our group audit mainly focused on significant group entities.

We have performed audit procedures ourselves at group entities.

By performing the procedures mentioned above at group entities, together with additional procedures at group level, we have been able to obtain sufficient and appropriate audit evidence about the group's financial information to provide an opinion on the consolidated financial statements.

Audit approach fraud risks

We identified and assessed the risks of material misstatements of the financial statements due to fraud. During our audit we obtained an understanding of the entity and its environment and the components of the system of internal control, including the risk assessment process and management's process for responding to the risks of fraud and monitoring the system of internal control and how the Supervisory board exercises oversight, as well as the outcomes. A fraud risk assessment is a visible component of the internal control environment.

We evaluated the design and relevant aspects of the system of internal control and in particular the fraud risk assessment, as well as among others the code of conduct, whistle blower procedures and incident registration. We evaluated the design and the implementation and, where considered appropriate, tested the operating effectiveness, of internal controls designed to mitigate fraud risks.

As part of our process of identifying fraud risks, we evaluated fraud risk factors with respect to financial reporting fraud, misappropriation of assets and bribery and corruption and from time to time in co-operation with our forensic specialists. We evaluated whether these factors indicate that a risk of material misstatement due fraud is present.

We did not identify fraud risk factors with respect to revenue recognition. We have assessed the accuracy of gross rental income based on a test of detail and analytical procedures on the tenancy schedule and linked the completeness to the property portfolio. We have performed an integral assessment of the recorded gross rental income based on the substantive analytical procedures performed using the tenancy schedules and property portfolio.

We identified the following fraud risks and performed the following specific procedures:

Fraud risk	How the fraud risk was addressed in the audit
Management override of controls
We presume a risk of material misstatement due to fraud related to management override of controls. Management is in a unique position to perpetrate fraud because of management's ability to manipulate accounting records and prepare fraudulent financial statements by overriding controls that otherwise appear to be operating effectively.	Our audit procedures included, among others, the following: We incorporated elements of unpredictability in our audit. We also considered the outcome of our other audit procedures and evaluated whether any findings were indicative of fraud or noncompliance. We considered available information and made inquiries of relevant persons during the year and at year end (including management, general counsel, internal auditor, compliance officer and risk management). Additionally we requested confirmation from the depositary on the ownership of assets and any irregularities. We have performed a review of available minutes for the relevant organizational bodies and have obtained and reviewed the ISAE 3402 type 2 reports over 2022 of Bouwinvest Real Estate Investors B.V. having made appropriate links to our risk assessment and relevant controls.We tested the appropriateness of journal entries recorded in the general ledger and other adjustments made in the preparation of the financial statements. We evaluated whether the selection and application of accounting policies, particularly those related to subjective measurements and complex transactions, may be indicative of fraudulent financial reporting. We evaluated whether the judgments and decisions made by management in making the accounting estimates included in the financial statements indicate a possible bias that may represent a risk of material misstatement due to fraud. Management insights, estimates and assumptions that might have a major impact on the financial statements are disclosed in note 4, 12, and 13 of the financial statements. We performed a retrospective review of management judgments and assumptions related to significant accounting estimates reflected in prior year financial statements. Valuation of investment property is a significant area to our audit as the valuation is inherently judgmental in nature, due to the use of assumptions that are highly sensitive, any change in assumptions may have a significant effect on the outcome given the relative size of the investment property balance. Reference is made to the section “Our key audit matter”. For significant transactions, we evaluated whether the business rationale of the transactions suggests that they may have been entered into to engage in fraudulent financial reporting or to conceal misappropriation of assets. As part of our audit procedures, we verified whether the significant transactions should be considered related-party transactions. This did not lead to indications for fraud potentially resulting in material misstatements.

Audit approach fraud risks compliance with laws and regulations

We assessed the laws and regulations applicable to the company via our inquiries with management and other personnel, and our assessment of relevant correspondence.

As a result of our risk assessment procedures, and while realizing that the effects from non-compliance could considerably vary, we considered the following laws and regulations: adherence to the Dutch Financial Supervision Act, the Money Laundering and Terrorist Financing (Prevention) Act, the requirements for fiscal investment institutions in the Corporation Tax Act 1969, the Alternative Investment Fund Managers Directive (AIFMD), and the requirements under the International Financial Reporting Standards as adopted by the European Union (EU-IFRS) and Part 9 of Book 2 of the Dutch Civil Code with a direct effect on the financial statements as an integrated part of our audit procedures, to the extent material for the related financial statements.

We obtained sufficient appropriate audit evidence regarding provisions of those laws and regulations generally recognized to have a direct effect on the financial statements.

Apart from these, the Bouwinvest Dutch Institutional Office Fund N.V. is subject to other laws and regulations where the consequences of non-compliance could have a material effect on amounts and/or disclosures in the financial statements, for instance, through imposing fines or litigation.

Given the nature of Bouwinvest Dutch Institutional Office Fund N.V.’s business and the complexity of the regulatory environment, there is a risk of non-compliance with the requirements of such laws and regulations.

Our procedures are more limited with respect to these laws and regulations that do not have a direct effect on the determination of the amounts and disclosures in the financial statements. Compliance with these laws and regulations may be fundamental to the operating aspects of the business, to Bouwinvest Dutch Institutional Office Fund N.V.’s ability to continue its business, or to avoid material penalties and therefore non-compliance with such laws and regulations may have a material effect on the financial statements. Our responsibility is limited to undertaking specified audit procedures to help identify non-compliance with those laws and regulations that may have a material effect on the financial statements. Our procedures are limited to (i) inquiry of the Management Board and others within Bouwinvest Dutch Institutional Office Fund N.V. as to whether the Bouwinvest Dutch Institutional Office Fund N.V. is in compliance with such laws and regulations and (ii) inspecting correspondence, if any, with the relevant licensing or regulatory authorities to help identify non-compliance with those laws and regulations that may have a material effect on the financial statements.

Naturally, we remained alert to indications of (suspected) non-compliance throughout the audit.

Finally, we obtained written representations that all known instances of (suspected) fraud or non-compliance with laws and regulations have been disclosed to us.

Audit approach going concern

The Financial Statements of Bouwinvest Dutch Institutional Office Fund N.V. have been prepared on the basis of the going concern assumption. As indicated in the responsibilities of the Management Board below, the Management Board is responsible for assessing the Bouwinvest Dutch Institutional Office Fund N.V.’s ability to continue as a going concern.

We have evaluated the Management Board assessment of the Bouwinvest Dutch Institutional Office Fund N.V.'s ability to continue as a going concern and inquired the Management Board regarding any knowledge of events or conditions beyond the period of the Management Board assessment. On the basis of our audit procedures, we have not identified any indication that would give rise to uncertainty on the Bouwinvest Dutch Institutional Office Fund N.V.'s ability to continue as a going concern. Bouwinvest Dutch Institutional Office Fund N.V. has total off-balance sheet items for a total of € 5.8 million due in the upcoming years. These off-balance sheet items will be financed via, (a) the available cash position as per 31 December 2022, (b) the cashflow from the operational result, (c) current and new commitments and capital calls, noting sufficient headroom in the current market circumstances. Furthermore we noted that there is no indication that cash positions and cash flows will be insufficient to meet future obligations. The tenant mix does not lead to concern over dependency on a single tenant or group of tenants in respect to the rental income and respective cash flows.

Bouwinvest Dutch Institutional Office Fund N.V. has a best effort requirement for redemption request (i.e. evaluate if the request can be acknowledged without negatively impacting the Fund) and no obligation to acknowledge the request immediately.

This did not lead to indications of the Bouwinvest Dutch Institutional Office Fund N.V. not being able to continue as a going concern.

Our key audit matters

Key audit matters are those matters that, in our professional judgement, were of most significance in our audit of the financial statements. We have communicated the key audit matters to the Management Board. The key audit matters are not a comprehensive reflection of all matters discussed.

These matters were addressed in the context of our audit of the financial statements as a whole and in forming our opinion thereon, and we do not provide a separate opinion on these matters.

Key audit matter

How the key audit matter was addressed in the audit

Valuation of investment property

Refer to notes 12 and 13 to the consolidated financial statements.

As at December 31, 2022, Bouwinvest Dutch Institutional Office Fund N.V. held a portfolio of investment property with a fair value of EUR 1,299 million (December 31, 2021: EUR 1,316 million).

The portfolio mainly consists of office properties.

At the end of each reporting period, the Board of the Manager determines the fair value of its investment property portfolio in accordance with the requirements of IAS 40 and IFRS 13.

Bouwinvest Dutch Institutional Office Fund N.V. uses external valuation reports issued by external independent professionally qualified valuers to determine the fair value of its investment property.

As the valuation of investment property is inherently judgmental in nature, due to the use of assumptions that are highly sensitive, any change in assumptions may have a significant effect on the outcome given the relative size of the investment property balance. The most significant assumptions and parameters involved, given the sensitivity and impact on the outcome, are the capitalization rate and market rent levels.

IFRS 13 seeks to increase consistency and comparability in fair value measurements and related disclosures through a 'fair value hierarchy'. The hierarchy categorizes the inputs used in valuation techniques into three levels. The hierarchy gives the highest priority to (unadjusted) quoted prices in active markets for identical assets or liabilities and the lowest priority to unobservable inputs. (Unobservable) inputs are used to measure fair value to the extent that relevant observable inputs are not available, thereby allowing for situations in which there is little, if any, market activity for the asset at the measurement date. Fair value measurements categorized within Level 3 have the lowest priority as the valuation is predominately based on unobservable inputs and those measurements have a greater degree of uncertainty and subjectivity. This means that a valuation at Level 3 has a fairly large measure of estimation uncertainty and as a result a fairly large bandwidth of valuation uncertainty in which a valuation can been seen reasonable in the light of IFRS 13.

In addition, and as the external appraiser has recommended in its assessment of the fair value of the property portfolio, caution is needed in analyzing the values due to the unknown future impacts on economy and real estate markets.

Our audit procedures included, among others, the following:

We have gained understanding of the valuation process and tested design and implementation of Bouwinvest Dutch Institutional Office Fund’s relevant controls with respect to the data used in the valuation of the property portfolio.

We noted that management involved established parties to assist with the valuation of the investment properties. We evaluated the competence of Bouwinvest Dutch Institutional Office Fund N.V.’s external appraiser, which included consideration of their qualifications and expertise.

In relation to the significant assumptions in the valuation of investment property we have:

Determined that the valuation methods as applied by the Management Board, as included in the valuation reports, are appropriate and consistent with prior year.
Challenged the significant assumptions (such as capitalization rate, market rental income, market-derived discount rate) against relevant market data. We have involved our internal real estate valuation experts in these assessments.
Assessed the sensitivity analysis on the key input data and assumptions to understand the impact of reasonable changes in assumptions on the valuation;
Assessed the appropriateness of the disclosures relating to the assumptions used in the valuations and sensitivity analysis in the notes to the consolidated financial statements.

Observation

We found that, with the (significant) assumptions used in the valuation reports, the valuation of the investment property is valued within a reasonable range in the light of the valuation uncertainty for level 3 valuations.

Report on the other information included in the annual report

The annual report contain other information, in addition to the financial statements and our auditor's report thereon.

The other information consists of:

Management Board's Report.
Other Information as required by Part 9 of Book 2 of the Dutch Civil Code.
Other included information.

Based on the following procedures performed, we conclude that the other information:

Is consistent with the financial statements and does not contain material misstatements.
Contains all the information regarding the management report and the other information as required by Part 9 of Book 2 of the Dutch Civil Code.

We have read the other information. Based on our knowledge and understanding obtained through our audit of the financial statements or otherwise, we have considered whether the other information contains material misstatements.

By performing these procedures, we comply with the requirements of Part 9 of Book 2 of the Dutch Civil Code and the Dutch Standard 720. The scope of the procedures performed is substantially less than the scope of those performed in our audit of the financial statements.

Management Board is responsible for the preparation of the other information, including Report of the Board of Directors in accordance with Part 9 of Book 2 of the Dutch Civil Code, and the other information as required by Part 9 of Book 2 of the Dutch Civil Code.

Description of responsibilities regarding the financial statements

Responsibilities of Management Board for the financial statements

Management Board is responsible for the preparation and fair presentation of the financial statements in accordance with EU-IFRS and Part 9 of Book 2 of the Dutch Civil Code. Furthermore, Management Board is responsible for such internal control as Management Board determines is necessary to enable the preparation of the financial statements that are free from material misstatement, whether due to fraud or error.

As part of the preparation of the financial statements, Management Board is responsible for assessing the company's ability to continue as a going concern. Based on the financial reporting frameworks mentioned, Management Board should prepare the financial statements using the going concern basis of accounting unless Management Board either intends to liquidate the company or to cease operations, or has no realistic alternative but to do so.

Management Board should disclose events and circumstances that may cast significant doubt on the company's ability to continue as a going concern in the financial statements.

Our responsibilities for the audit of the financial statements

Our objective is to plan and perform the audit assignment in a manner that allows us to obtain sufficient and appropriate audit evidence for our opinion.

Our audit has been performed with a high, but not absolute, level of assurance, which means we may not detect all material errors and fraud during our audit.

Misstatements can arise from fraud or error and are considered material if, individually or in the aggregate, they could reasonably be expected to influence the economic decisions of users taken on the basis of these financial statements. The materiality affects the nature, timing and extent of our audit procedures and the evaluation of the effect of identified misstatements on our opinion.

We have exercised professional judgement and have maintained professional skepticism throughout the audit, in accordance with Dutch Standards on Auditing, ethical requirements and independence requirements. Our audit included among others:

Identifying and assessing the risks of material misstatement of the financial statements, whether due to fraud or error, designing and performing audit procedures responsive to those risks, and obtaining audit evidence that is sufficient and appropriate to provide a basis for our opinion. The risk of not detecting a material misstatement resulting from fraud is higher than for one resulting from error, as fraud may involve collusion, forgery, intentional omissions, misrepresentations, or the override of internal control.
Obtaining an understanding of internal control relevant to the audit 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's internal control.
Evaluating the appropriateness of accounting policies used and the reasonableness of accounting estimates and related disclosures made by Management Board.
Concluding on the appropriateness of Management Board use of the going concern basis of accounting, and based on the audit evidence obtained, whether a material uncertainty exists related to events or conditions that may cast significant doubt on the company's ability to continue as a going concern. If we conclude that a material uncertainty exists, we are required to draw attention in our auditor's report to the related disclosures in the financial statements or, if such disclosures are inadequate, to modify our opinion. Our conclusions are based on the audit evidence obtained up to the date of our auditor's report. However, future events or conditions may cause the company to cease to continue as a going concern.
Evaluating the overall presentation, structure and content of the financial statements, including the disclosures.
Evaluating whether the financial statements represent the underlying transactions and events in a manner that achieves fair presentation.

Because we are ultimately responsible for the opinion, we are also responsible for directing, supervising and performing the group audit. In this respect we have determined the nature and extent of the audit procedures to be carried out for group entities. Decisive were the size and/or the risk profile of the group entities or operations. On this basis, we selected group entities for which an audit or review had to be carried out on the complete set of financial information or specific items.

We communicate with management regarding, among other matters, the planned scope and timing of the audit and significant audit findings, including any significant findings in internal control that we identified during our audit.

From the matters communicated with Management Board, we determine the key audit matters: those matters that were of most significance in the audit of the financial statements. We describe these matters in our auditor's report unless law or regulation precludes public disclosure about the matter or when, in extremely rare circumstances, not communicating the matter is in the public interest.
