document or schedule in which an accountant or auditor gathers information to substantiate an opinion concerning an account BALANCE or TEST OF TRANSACTION. Types of work sheets that may be prepared are: (1) test of transaction information showing the sample selected, attributes tested, findings for each item in the sample, and the sample as a whole; (2) BANK RECONCILIATION; (3) schedule of FIXED ASSETS; and (4) analysis of various expenses with conclusions on the findings. A group of assembled work sheets becomes the WORK PAPERS  composing the documentation for the audit or review work performed by the accountant. The accountant will base the audit opinion and other comments on this group of work sheets. It should be noted that work sheets may include letters, minutes of meetings, and other items not prepared by the auditor.
