Material weakness
Material weakness means a deficiency or combination of deficiencies in the internal control over information in contractor business systems, such that there is a reasonable possibility that a material misstatement of such information will not be prevented, or detected and corrected, on a timely basis. A reasonable possibility exists when the likelihood of an event occurring is (1) Probable; or (2) More than remote but less than likely (section 806 of Pub. L. 116-283).
