FDI Screening and Export Controls for Technology Companies in the United States, the European Union and Ukraine — Averites Legal Insights

FDI Screening and Export Controls for Technology Companies in the United States, the European Union and Ukraine

Know-how, source code, a minority investment or an internal restructuring can trigger export-control or foreign investment screening rules before any physical product crosses the border. Technology businesses operating across the United States, the European Union, and Ukraine should classify sensitive information, map investor rights, and control disclosure before diligence, signing, and closing.

Tax Fraud Allegations for International Businesses in Europe, the US, and Ukraine — Averites Legal Insights

Tax Fraud Allegations for International Businesses in Europe, the US, and Ukraine

Five lessons for international businesses An additional tax assessment, a defective invoice, or a problem elsewhere in a supply chain does not, by itself, establish tax fraud. Across the European Union, the United States, and Ukraine, authorities must prove the relevant taxpayer's conduct and the required state of mind. International groups therefore need entity-specific evidence that is consistent across jurisdictions.

Force Majeure Under English and Ukrainian Law for Cross Border Contracts — Averites Legal Insights

Force Majeure Under English and Ukrainian Law for Cross Border Contracts

A practical guide for businesses and construction projects War, sanctions, pandemics, and infrastructure failures do not automatically excuse contractual performance under English or Ukrainian law. The result turns on the governing law, the clause, notice requirements, and evidence that the event caused the specific breach. Businesses should test these points when drafting and again as soon as disruption occurs.
