Notwithstanding the provisions of article D. 3324-2, the added value of banking and insurance companies is determined as follows:
1° For credit institutions and finance companies, by banking income excluding tax plus net income from the securities portfolio and income from real estate. Banking income is equal to the difference between, on the one hand, collections from customers and, on the other hand, financial expenses of all kinds;
2° For insurance companies governed by the Insurance Code and reinsurance companies, by the difference between, on the one hand, the sum of premiums net of tax and investment income and, on the other hand, the total allocations to technical provisions and benefits paid during the financial year to policyholders and beneficiaries of insurance contracts.
