Dr Olumide Obayemi, Legal Practitioner, Ajumogobia & Okeke and Senior Lecturer, Department of Business Law, Lagos State University Ojo, examines an important topic that straddles corporate law, corporate finance and taxation. In his article, “Enacting Anti-Thin Capitalisation Rules for Nigeria”, he examines a financing strategy mostly favoured by multinational corporations (MNCs) in making investments outside their home nations. As debt is often a more tax efficient method of finance than equity because interest is tax deductible while dividend is not, most jurisdictions have prescribed rules to deal with the debt/equity mix by placing a ceiling on debt/equity ratio so that their tax base is not eroded as foreign firms finance their subsidiaries with excessive debt. Dr Obayemi explores anti-thin capitalisation rules in several jurisdictions and advocates the enactment of effective anti-thin capitalisation rules in Nigeria with a safe harbour of 1.5 to 1 debt-to-equity as the starting point.
