Quin Co. is a large public food retailer, listed on the TSX, with over 1,500 stores operating across Canada. Sears & Tilly CPAs (S&T) has performed the yearly audit of Quin for the past 10 years. Recently, the CFO of Quin, Jason, has approached the auditor about performing a quarterly interim financial statement review. Currently, Quin does not have its statements reviewed quarterly. 

Jason would like reassurance from the auditors quarterly about the financial statements to ensure all errors are detected.

Required: 

Prepare a memo to Jason explaining what a review of interim financial statements consists of and how it differs from the annual financial statement audit.
