Reporting on internal control under Government Auditing Standards differs from reporting under generally accepted auditing standards in that Government Auditing Standards requires a

a. Written report describing the entity's internal control procedures specifically designed to prevent fraud, abuse, and illegal acts.

b. Written report describing each reportable condition observed including identification of those considered material weaknesses.

c. Statement of negative assurance that the internal control procedures not tested have an immaterial effect on the entity's financial statements.

d. Statement of positive assurance that internal control procedures designed to detect material errors and fraud were tested.
