Answer:
In any case, the loss should not be yours. Your customer may come to you with an affidavit of forgery from the business. If so, you will make a claim against the depositary bank because they guaranteed the payee's endorsement. Their liability to your bank is clear enough. Whether the depositary bank absorbs the entire loss may depend on the status the employee held within the drawer's business and how much due diligence the depositary bank did when it opened the account. There's no clear cut answer except in the mind of a judge who will have all of the facts.
