This document discusses various types of assurance and attestation engagements that accountants can perform beyond the traditional audit. It describes review and compilation services, which involve compiling or reviewing financial statements but providing varying levels of assurance (none for compilation, limited for review). It also covers interim reviews for public companies, attestation standards, WebTrust and SysTrust services assessing online trust principles, engagements on prospective financial statements, agreed-upon procedures, and other assurance services like compilations using other bases of accounting or auditing specific elements of financial statements. The level of evidence required and assurance provided differs across these engagements.
