Final answer:
A Product Summary is not a route in the retail loan process; it is informational content. The other options—Underwriting, Document Manager, and Application—are all integral parts of the retail loan origination process.
Step-by-step explanation:
The question relates to the identification of components that are not part of the retail loan process. When we look at the options provided: A) Product Summary, B) Underwriting, C) Document Manager, and D) Application, we can evaluate each component's relevance to the retail loan origination process.
Underwriting (B) is the process lenders use to assess the creditworthiness of a potential borrower. The Application (D) is the initial step where the borrower provides personal and financial information. Document Manager (C) would typically be a system that organizes and stores the documents required for loan processing. However, Product Summary (A) does not represent a step or route in the retail loan process. Instead, a Product Summary would generally provide an overview of the loan products available, which is informational content rather than a procedural step.
Therefore, the answer to which of the following is not a retail loan route is A) Product Summary, as it is not a procedural step in the loan origination process.
