FINANCIAL DATA Statutory Auditors’ report on the consolidated financial statements

Insurance technical reserves Risk identified and main judgments

Our audit approach We used the actuarial specialists to assist us in auditingthese items. Depending on the type of risks covered by the reserves, the main audit procedures applied included: obtaining an understanding of the general conditions relating to V insurance contracts marketed by the Group; assessing the methods and assumptions used to calculate these V provisions, in particular their compliance with applicable regulations, market practices and the economic and financial context made more uncertain by the health crisis; testing, on the basis of accounting reconciliation, recurrence tests, V or surveys, the reliability of information relating to insurance contracts recorded in the management systems and used for the valuation of technical reserves; carrying out, based on a sample of policies, an independent V recalculation of certain reserves; assessing calculation methods and the result of the liability V adequacy test, as required under IFRS 4. We also verified the information on insurance liabilities disclosed in the notes to the Group’s consolidated financial statements. Our audit approach We acquired information on how budgetary data is compiled to estimate future taxable profits and assessed the reliability of the process of drawing up the tax business plans that are the basis of our assessment of the probability of the Group recovering its deferred tax assets by: examining how the last business plan used as a basis of the V estimates was developed and approved; comparingprojected results of previous years to the actual results V for those years; assessing the reasonableness of the forecast assumptions and V the inputs used by management to estimate future profits and the recoverability of recognized deferred tax assets, based on our experience and knowledge of the Group’s activities andstrategy. With the help of our specialists, we verified the appropriateness of the model adopted by management to identify existing tax loss carryforwards to be used, whether through deferred tax liabilities or future taxable profits. Based on projections made by management, we performed tests to check that deferred tax asset bases are properly calculated and that the right tax rates are used.

As part of its insurance business, the Natixis Group recognizes technical reserves that represent its commitments towards policyholders. We considered the valuation of these provisions to be a key audit matter insofar as they represent a significant amount in the Group’s financial statements and since some of these reserves require the exercise of judgment in determining the assumptions (e.g. experience tables and behavioral statistics) or calculation models used, particularly in the context of the Covid-19 pandemic. Liabilities related to insurance policies amounted to €104,182 million at December 31, 2020. Please refer to Notes 5.22 and 8.5 to the consolidated financial statements for more details.

Deferred tax assets related to tax loss carryforwards Risk identified and main judgments

5

The NatixisGroup recognizesdeferredtax assetsat the reportingdate in respect of tax loss carryforwardswhen it is considered likely that the tax entity concernedwill have future taxable profits that tax loss carryforwards may be set off against, within a certain timfreame. The estimate of the ability to generate future taxable profits within this period requires the exercise of judgment on the part of management, including in developing tax business plans, to justify the recognition of deferred tax assets. We identified this issue as a key audit matter due to the sensitivity of deferred tax assets thus recognized to the assumptionsand options adopted by management. At December 31, 2020, €1,196millionwas recordedon Natixis’ consolidated balance sheet under deferred tax assets, including €758 million in tax loss carryforwards. Please refer to Notes 5.22 and 7.8 to the consolidated financial statements for more details.
