Corporate finance theory seeks to understand how incorporated firms address the financial constraints that affect their investment decisions. This is achieved by using varied financial instruments that seek to give holders different claims on the firm's assets. Recent scholarship in this area has highlighted the critical importance of the legal environment in explaining the choices that companies make about their capital structure. This book combines company law, capital markets law, and aspects of commercial and insolvency law to give readers a detailed understanding of the legal and regulatory issues relating to corporate finance. Informed by insights from theoretical and empirical work, the book examines from a legal perspective the key elements of corporate financing structures and capital markets in the UK. The authors' practical experience of transactions and regulatory issues ensures that thorough scholarly inquiry and critical reflection are complemented by an assured understanding of the interface between legal principles and rules as they are documented and in their actual operation. Key developments covered in this third edition include the post-Brexit adaptation of UK company law and capital market regulation, important new cases on parent company liability in tort, creditor-facing duties of directors, issuer and director liability for misleading statements to the market, alternatives to public market financing, and recent changes in the practice of debt finance such as the emergence of non-bank lenders.
