During the preparation of the bank reconciliation for Apache Grading Co., Sarah Ferrari, the assistant controller, discovered that Rocky Spring Bank incorrectly recorded a $610 check written by Apache Grading Co. as $160. Sarah has decided not to notify the bank but wait for the bank to detect the error. Sarah plans to record the $450 error as Other Income if the bank fails to detect the error within the next three months.
Discuss whether Sarah is behaving in a professional manner.
