Definitions in company law define core concepts: company, director, prospectus, managing director and related corporate terms. Section 2 furnishes the statutory definitions central to company law, specifying the meanings of corporate forms (company, public/private, holding and subsidiary), constitutional documents (memorandum, articles), governance roles (Board, director, managing director, manager, secretary, officer who is in default), and key financial and securities terms (prospectus, debenture, paid up capital, financial year, securities, depository). It cross-references other statutes for certain terms, limits managerial powers by proviso, and records amendments and exclusions that shape application of these definitions.
