Such advantages can take the form of direct grants, loans on favorable terms, guarantees, equity stakes, tax concessions, or the provision of goods or services below market value, and may cover support to firms, sectors, or specific projects. State aid is typically evaluated against the principle that public intervention should not unduly distort competition or affect trade within the jurisdiction.
