The case of McKesson & Robbins scandal (1938) was happen due to internal fraud. This case is also happen by the faulty work of board of directors. The organization of McKesson & Robbins, Inc. had been taken on by Phillip Musica in the year of 1925. Musica also used a assumed names by that he did hide his original identity and due to this he did take the control of management in two companies. In the context of Adelphia Pharmaceutical, Musica used the name such as Frank D. Costa and also used F. Donald Coster for the organization of McKesson & Robbins. Even though, Musica was expanded the legitimate the business operations of the company successfully. But he also recruited his brothers in both the organizations by their hiding identity in which his two brother took the part inside the company and one did his work from the outside of he company (Clikeman, 2008). With the help of this, Musica generated fake documents related to the sales of company and also paid huge commissions to the company of shell distribution by the help of their control. They also made internal transactions for them and also made the assets about the $20 million by making phony balance sheet.

There was several defects in the internal systems of the company by that Musica did non ethical work and also made huge money for their self on the basis of companies assets. The internal audit of the company also was weak and the recruitment system of the  company by that Msica did  make huge money. Hence, the management would use the audit tests of internal controls that would help the auditors to stop the internal misconduct (Clikeman, 2008). With the help of this, the organization would improve the internal systems of the company also reduces the internal fraud.
