You are the engagement partner for Clark co Enterprises, a company listed on the Major Stock Exchange. You are reviewing the year-end working papers prior to 2 preparing the audit report. You notice that the audit manager on the file, Stephen, has recommended a clean audit report. Indeed, there are no material errors noted in the file based on substantive testing. However, you cannot find the legal letter in the file. When you call Stephen to check, you find that they, apparently, forgot to get one. 

a. Explain to Stephen the importance of the legal letter?

b. At this point, what is your only reporting option?
