Business case

The Shareholder and Management of the Client engaged Grant Thornton Kazakhstan to conduct a forensic investigation at one of the largest petrochemical plants in Kazakhstan (hereinafter referred to as the "Target Company"). The Target Company supplies its products both to the local market and exports them to countries in the near and far abroad. The Client had concerns about the integrity of the top management of the Target Company. The primary questions that troubled the Client were: Is there a practice of selling products at reduced prices? Are the procurements truly aligned with actual needs and at fair/non-inflated prices? Are there any suspicious transactions? Are the controls adequate to prevent fraud? Are there any indications of control circumvention?
