During the preparation of the bank reconciliation for Colonial Co., Javier Frailey, the assistant controller, discovered that El Camino National Bank incorrectly recorded an $819 check written by Colonial Co. as $189. Javier has decided not to notify the bank but wait for the bank to detect the error. Javier plans to record the $630 error as Other Income if the bank fails to detect the error within the next three months.
Discuss whether Javier is behaving in a professional manner.
