When a public company receives the certificate of incorporation, this implies that

A certificate of incorporation is the legal document issued by the relevant government body confirming that a company has been registered and now exists as a separate legal person. Once a public company receives this certificate, it becomes a distinct legal entity, meaning its assets and liabilities exist separately from those of its individual members (shareholders). This separation is what protects shareholders' personal property from the company's debts, since the company itself, not its members personally, owns its assets and owes its debts.

The other statements are inaccurate for a public company at this stage. Incorporation does not stop a company from suing or being sued; on the contrary, becoming a separate legal person is precisely what allows it to sue and be sued in its own name. Incorporation does not automatically make it difficult to raise capital; in fact, a public company's separate legal status and limited liability make it easier to attract investors. Finally, a public company generally needs an additional document, the certificate of trading (or certificate to commence business), before it can actually start trading; the certificate of incorporation alone does not permit it to begin business operations.

Examination reminder: separate legal personality, giving the company its own identity distinct from its owners, is the single most important consequence of incorporation and is frequently tested.
