During 20Y5, the accountant discovered that the physical inventory at the end of 20Y4 had been understated by $42,750.

When an error is discovered affecting the prior period, it should be corrected. In this case, the inventory account should be debited and the owner's capital account credited for $42,750. b. Failure to correct the error for 20Y4 and purposely misstating the inventory and the cost of goods sold in 20Y5 would cause the income statements for the two years to not be comparable. c. The balance sheet at the end of 20Y5 would be incorrect unless an adjustment is made. d. "When an error is discovered affecting the prior period, it should be corrected. In this case, the inventory account should be debited and the owner's capital account credited for $42,750." and "Failure to correct the error for 20Y4 and purposely misstating the inventory and the cost of goods sold in 20Y5 would cause the income statements for the two years to not be comparable." are correct. X e.
