Wilkins Food Products, Inc., acquired a packaging machine from Lawrence Specialists Corporation. Lawrence completed construction of the machine on January 1, 2009. In payment for the machine Wilkins issued a three-year installment note to be paid in three equal payments at the end of each year. The payments include interest at the rate of 10%.

Lawrence made a conceptual error in preparing the amortization schedule, which Wilkins failed to discover until 2011. The error had caused Wilkins to understate interest expense by $45,000 in 2009 and $40,000 in 2010.

2. Prepare a journal entry to correct the error.
3. What other step(s) would be taken in connection with the error?
