If the carrying amount is higher than the recoverable amount, an adjustment is made in the income OWN SHARES statement through additional depreciation. Own shares in the capital of aventron AG are recognised at cost and reported as a negative item under equity. LIABILITIES Liabilities are recognised at their nominal value.

CASH FLOW STATEMENT BENEFIT OBLIGATIONS Cash and cash equivalents without securities are used as funds. At the end of the year, staff employed by the aventron Group in Funds thus comprise cash balances, post and bank balances Switzerland were insured with the collective occupational benefit payable on demand, as well as fixed-term deposits and money plan (BVG) foundation Swiss Life. Staff employed by Birseck market receivables with a maturity of less than 90 days. Hydro SAS are insured by the collective foundation REUNICA. The other foreign aventron companies have no employees. The economic impacts of benefit obligations on aventron are presented in accordance with FER 16. Their benefits and economic obligations are derived directly from contractual and statutory bases. An economic benefit arises if aventron realises positive effects on future cash flows (e.g. excess coverage, employer contribution reserves). Economic obligations arise from negative future effects on cash flow (e.g. insufficient coverage, restructuring obligations).

DEFERRED TAXES Deferred tax assets are recognised on the basis of loss carry-forwards that aventron considers tax-deductible (see financial assets). Deferred tax liabilities are formed by applying the liability method to any differences between FER values and any carrying amounts relevant for tax purposes. A tax rate of 20 percent before taxes was applied for Swiss companies without holding privilege, and for those with holding privilege this was taken into account accordingly for the tax rate. A tax rate of 28 percent was applied for companies in France. In Norway, the tax rate is 22 percent, in Germany between nine and 30 percent, in Spain 25 percent and in Italy 24 to 28 percent.

The expected tax rate in 2019 is 18.2 percent (previous year: 15.7 percent) and corresponds to the weighted average tax rate based on the earnings before tax of all Group companies.

In 2019, the effective tax rate of 20.3 percent (previous year: 14.0 percent) is above the expected tax rate. This difference is attributable to the impact of non tax deductible expenses, changes in tax rates and adjustment to deferred taxes of previous years.

In the reporting period, the depreciation duration of goodwill for infrastructure plans was adjusted from 5 to 20 years. The long-term plants exhibit a useful life of 20 to 60 years. Depreciation over 20 years is thus in agreement with the lifetime and is a more accurate reflection of the economic facts. For the remaining goodwill, the depreciation is still over 5 years. This is a change in an estimation, which was implemented prospectively on 1 January 2019.

With activation and depreciation of the goodwill, there was a goodwill balance of kCHF 41,454 (previous year: kCHF 39,109) at the end of the year. The mathematical depreciation would reduce the earnings and the annual profit/loss by kCHF 2,325 (previous year: kCHF 15,609). The acquisition cost as at 31 December 2019 includes goodwill to the value of kCHF 1,776 (previous year: kCHF 1,733) which is assigned to minority interests. As a result of the change in depreciation period, the scheduled depreciation in 2019 fell by kCHF 13,492.

4446 Materiality The scope of our audit was influenced by our application of materiality. Our audit opinion aims to provide reasonable assurance that the consolidated financial statements are free from material misstatement. Misstatements may arise due to fraud or error. They are considered material if, individually or in aggregate, they could reasonably be expected to influ- ence the economic decisions of users taken on the basis of the consolidated financial statements.

Based on our professional judgement, we determined certain quantitative thresholds for materiality, including the overall Group materiality for the consolidated financial statements as a whole as set out in the table below. These, together with qualitative considerations, helped us to determine the scope of our audit and the nature, timing and extent of our audit procedures and to evaluate the effect of misstatements, both individually and in aggregate, on the consolidated financial statements as a whole.

Overall Group materiality CHF 6'000'000

How we determined it 1% of total assets

Rationale for the materiality bench- We chose total assets as the benchmark for Group materiality because this mark applied properly takes into account the capital-intensive nature of the aventron Group.

We agreed with the Audit Committee that we would report to them misstatements above CHF 300'000 identified during our audit as well as any misstatements below that amount which, in our view, warranted reporting for qualitative reasons.

Audit scope We tailored the scope of our audit in order to perform sufficient work to enable us to provide an opinion on the consoli- dated financial statements as a whole, taking into account the structure of the Group, the accounting processes and con- trols, and the industry in which the Group operates.

The consolidated financial statements include 88 fully consolidated companies in the consolidation group, mostly repre- senting individual hydropower plants, solar power plants or wind power plants. None of these entities, taken individually, is classified as a substantial component in terms of its size or its risk profile. In order to achieve adequate audit cover- age, the most important entities were selected to define the audit scope.

Entities subject to a statutory audit were mandated to the local auditor with instructions to check whether the financial information of each entity was in accordance with the finance manual of aventron AG. The local auditors were PwC Net- work firms and third parties.

For entities not subject to a statutory audit, the Group auditor performed a centralised review of their revenues and prop- erty, plant and equipment. We gained additional coverage at entities whose statutory audits were completed at the time of the audit of the consolidated financial statements. We reviewed the reconciliations of financial information included in the statutory financial statements and relevant to the consolidated financial statements.

The assessment of whether indicators of impairment might exist for individual assets was performed centrally by us as the Group auditor.

None of the entities that were not included in the audit scope contributes more than 3% of revenues and property, plant and equipment of the Group. At Group level, analytical audit procedures were performed that focussed on revenues and property, plant and equipment in order to exclude the possibility that the financial information of these entities included in the consolidated financial statements contained material misstatements.

Report on key audit matters based on the circular 1/2015 of the Federal Audit Oversight Authority Key audit matters are those matters that, in our professional judgement, were of most significance in our audit of the consolidated financial statements of the current period. These matters were addressed in the context of our audit of the consolidated financial statements as a whole, and in forming our opinion thereon, and we do not provide a separate opinion on these matters.

Responsibilities of the Board of Directors for the consolidated financial statements The Board of Directors is responsible for the preparation of the consolidated financial statements that give a true and fair view in accordance with Swiss GAAP FER and the provisions of Swiss law, and for such internal control as the Board of Directors determines is necessary to enable the preparation of consolidated financial statements that are free from mate- rial misstatement, whether due to fraud or error.

In preparing the consolidated financial statements, the Board of Directors is responsible for assessing the Group’s ability to continue as a going concern, disclosing, as applicable, matters related to going concern and using the going concern basis of accounting unless the Board of Directors either intends to liquidate the Group or to cease operations, or has no realistic alternative but to do so.

aventron AG | Report of the statutory auditor to the General Meeting

48 Auditor’s responsibilities for the audit of the consolidated financial statements Our objectives are to obtain reasonable assurance about whether the consolidated financial statements as a whole are free from material misstatement, whether due to fraud or error, and to issue an auditor’s report that includes our opinion. Reasonable assurance is a high level of assurance, but is not a guarantee that an audit conducted in accordance with Swiss law and Swiss Auditing Standards will always detect a material misstatement when it exists. Misstatements can arise from fraud or error and are considered material if, individually or in the aggregate, they could reasonably be ex- pected to influence the economic decisions of users taken on the basis of these consolidated financial statements.

As part of an audit in accordance with Swiss law and Swiss Auditing Standards, we exercise professional judgment and maintain professional scepticism throughout the audit. We also:

• Identify and assess the risks of material misstatement of the consolidated financial statements, whether due to fraud or error, design and perform audit procedures responsive to those risks, and obtain 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, misrep- resentations, or the override of internal control.

• Obtain an understanding of internal control relevant to the audit in order to design audit procedures that are appropri- ate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Group’s internal control.

• Evaluate the appropriateness of accounting policies used and the reasonableness of accounting estimates and re- lated disclosures made.

• Conclude on the appropriateness of the Board of Directors’ 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 Group’s ability to continue as a going concern. If we conclude that a material uncertainty ex- ists, we are required to draw attention in our auditor’s report to the related disclosures in the consolidated financial statements or, if such disclosures are inadequate, to modify our opinion. Our conclusions are based on the audit evi- dence obtained up to the date of our auditor’s report. However, future events or conditions may cause the Group to cease to continue as a going concern.

• Evaluate the overall presentation, structure and content of the consolidated financial statements, including the disclo- sures, and whether the consolidated financial statements represent the underlying transactions and events in a man- ner that achieves fair presentation.

• Obtain sufficient appropriate audit evidence regarding the financial information of the entities or business activities within the Group to express an opinion on the consolidated financial statements. We are responsible for the direction, supervision and performance of the Group audit. We remain solely responsible for our audit opinion.

We communicate with the Board of Directors or its relevant committee regarding, among other matters, the planned scope and timing of the audit and significant audit findings, including any significant deficiencies in internal control that we identify during our audit.

We also provide the Board of Directors or its relevant committee with a statement that we have complied with relevant ethical requirements regarding independence, and to communicate with them all relationships and other matters that may reasonably be thought to bear on our independence, and where applicable, related safeguards.

From the matters communicated with the Board of Directors or its relevant committee, we determine those matters that were of most significance in the audit of the consolidated financial statements of the current period and are therefore the key audit matters. 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, we determine that a matter should not be communicated in our report because the adverse consequences of doing so would reasonably be expected to outweigh the public interest benefits of such communication.

Basis for opinion We conducted our audit in accordance with Swiss law and Swiss Auditing Standards. Our responsibilities under those provisions and standards are further described in the “Auditor’s responsibilities for the audit of the financial statements” section of our report.

We are independent of the entity in accordance with the provisions of Swiss law and the requirements of the Swiss audit profession and we have fulfilled our other ethical responsibilities in accordance with these requirements. We believe that the audit evidence we have obtained is sufficient and appropriate to provide a basis for our opinion.

Our audit approach

Overview Overall materiality: CHF 4'500'000

We tailored the scope of our audit in order to perform sufficient work to enable us to provide an opinion on the financial statements as a whole, taking into ac- count the structure of the entity, the accounting processes and controls, and the industry in which the entity operates.

As key audit matter the following area of focus has been identified:

Impairment of holdings in and loans to Group companies

Materiality The scope of our audit was influenced by our application of materiality. Our audit opinion aims to provide reasonable assurance that the financial statements are free from material misstatement. Misstatements may arise due to fraud or error. They are considered material if, individually or in aggregate, they could reasonably be expected to influence the economic decisions of users taken on the basis of the financial statements.

Based on our professional judgement, we determined certain quantitative thresholds for materiality, including the overall materiality for the financial statements as a whole as set out in the table below. These, together with qualitative consider- ations, helped us to determine the scope of our audit and the nature, timing and extent of our audit procedures and to evaluate the effect of misstatements, both individually and in aggregate, on the financial statements as a whole.

Overall materiality CHF 4'500'000

How we determined it 1% of total assets

Rationale for the materiality bench- We chose total assets as the benchmark because this properly takes into ac- mark applied count the capital-intensive nature of aventron AG.

We agreed with the Audit Committee that we would report to them misstatements above CHF 225'000 identified during our audit as well as any misstatements below that amount which, in our view, warranted reporting for qualitative reasons.

Audit scope We designed our audit by determining materiality and assessing the risks of material misstatement in the financial state- ments. In particular, we considered where subjective judgements were made; for example, in respect of significant ac- counting estimates that involved making assumptions and considering future events that are inherently uncertain. As in all of our audits, we also addressed the risk of management override of internal controls, including among other matters consideration of whether there was evidence of bias that represented a risk of material misstatement due to fraud.

Report on key audit matters based on the circular 1/2015 of the Federal Audit Oversight Authority Key audit matters are those matters that, in our professional judgement, were of most significance in our audit of the fi- nancial statements of the current period. These matters were addressed in the context of our audit of the financial state- ments as a whole, and in forming our opinion thereon, and we do not provide a separate opinion on these matters.

We tested this analysis by assessing the methods used and by challenging the key assump- tions.

Our audit results support the assumptions used by Man- agement in assessing impairment of the holdings in and the loans to Group companies.

Responsibilities of the Board of Directors for the financial statements The Board of Directors is responsible for the preparation of the financial statements in accordance with the provisions of Swiss law and the company’s articles of incorporation, and for such internal control as the Board of Directors determines is necessary to enable the preparation of financial statements that are free from material misstatement, whether due to fraud or error.

In preparing the financial statements, the Board of Directors is responsible for assessing the entity’s ability to continue as a going concern, disclosing, as applicable, matters related to going concern and using the going concern basis of ac- counting unless the Board of Directors either intends to liquidate the entity or to cease operations, or has no realistic al- ternative but to do so.

aventron AG | Report of the statutory auditor to the General Meeting

58 Auditor’s responsibilities for the audit of the financial statements Our objectives are to obtain reasonable assurance about whether the financial statements as a whole are free from ma- terial misstatement, whether due to fraud or error, and to issue an auditor’s report that includes our opinion. Reasonable assurance is a high level of assurance, but is not a guarantee that an audit conducted in accordance with Swiss law and Swiss Auditing Standards will always detect a material misstatement when it exists. 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.

As part of an audit in accordance with Swiss law and Swiss Auditing Standards, we exercise professional judgment and maintain professional scepticism throughout the audit. We also:

• Identify and assess the risks of material misstatement of the financial statements, whether due to fraud or error, de- sign and perform audit procedures responsive to those risks, and obtain audit evidence that is sufficient and appropri- ate 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.

• Obtain an understanding of internal control relevant to the audit in order to design audit procedures that are appropri- ate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the entity’s internal control.

• Evaluate the appropriateness of accounting policies used and the reasonableness of accounting estimates and re- lated disclosures made.

• Conclude on the appropriateness of the Board of Directors’ 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 entity’s ability to continue as a going concern. If we conclude that a material uncertainty ex- ists, 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 entity to cease to continue as a going concern.

We communicate with the Board of Directors or its relevant committee regarding, among other matters, the planned scope and timing of the audit and significant audit findings, including any significant deficiencies in internal control that we identify during our audit.

We also provide the Board of Directors or its relevant committee with a statement that we have complied with relevant ethical requirements regarding independence, and to communicate with them all relationships and other matters that may reasonably be thought to bear on our independence, and where applicable, related safeguards.

From the matters communicated with the Board of Directors or its relevant committee, we determine those matters that were of most significance in the audit of the financial statements of the current period and are therefore the key audit matters. 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, we determine that a matter should not be communicated in our report because the adverse consequences of doing so would reasonably be expected to outweigh the public interest benefits of such communication.
