During the preparation of the bank reconciliation for Building Concepts Co., Joel Kimmel, the assistant controller, discovered that Lone Peak National Bank incorrectly recorded a $3,290 check written by Building Concepts Co. as $329. Joel has decided not to notify the bank but wait for the bank to detect the error. Joel plans to record the $2,961 error as Other Income if the bank fails to detect the error within the next three months.
