Challah is a partner in Challah & Co., CPAs, that is establishing a practice to include external auditing. Challah spends a lot of time keeping up-to-date on the latest recommendations and pronouncements in CAS, and Challah & Co. has an engagement team of 4 senior staff for each audit. The current audit of First Equipment Manufacturing Inc. (FEM) is at the stage of obtaining and documenting an understanding of the internal controls of the client. Challah's team assessed the internal controls as effective based on its discussion with FEM's management and management's explanation of how the internal controls work. This decision is supported by Challah's working papers, which consist of a narrative describing the control systems that collect FEM's data.

a.Can you Identify 4 items that are missing from Challah's working papers to support a decision on internal controls at FEM.

b.Assume that after reviewing the narrative description, Challah decided that the controls for the proper period objective were weak. Can you indicate how your testing approach would change with respect to this objective.

It is for auditing, thank you!
