Understanding the Error: Repairs on Second Hand Machinery

When a business purchases a second-hand asset, such as second hand machinery, any expenditure incurred to bring that asset into a working condition and ready for its intended use is considered a capital expenditure. This cost should be added to the cost of the asset itself and debited to the asset account (e.g., Machinery Account).

In this specific case, the repairs made to the second hand machinery before it was put to use are costs necessary to make the machinery usable. Therefore, these repair costs should be treated as capital expenditure and added to the cost of the machinery. The correct journal entry would be to debit the Machinery Account and credit Cash/Bank or a relevant payable account.

Identifying the Type of Error: Error of Principle

The question states that the repairs of second hand machinery purchased were debited to the repairs account. Debiting an expenditure to the Repairs Account treats it as a revenue expenditure. Revenue expenditures are costs incurred on maintaining an existing asset in good working order, not bringing it into use for the first time or significantly improving its capacity.

Mistaking a capital expenditure for a revenue expenditure, or vice versa, is a fundamental error in applying accounting principles. This type of mistake affects the classification of expenditure between the balance sheet (capital expenditure increases asset value) and the profit and loss account (revenue expenditure is an expense). An Error of Principle occurs when a transaction is recorded in contravention of fundamental accounting principles or rules.

Therefore, debiting the cost of repairs on second hand machinery (which is a capital expenditure) to the Repairs Account (treating it as a revenue expenditure) is a clear example of an Error of Principle.

Why Other Options Are Incorrect

• Compensating Error: This occurs when two or more errors cancel each other out. For example, if one account is debited with £100 too much, and another account is credited with £100 too much. This scenario doesn't involve a compensating error.
• Error of Omission: This occurs when a transaction is completely or partially omitted from the books of account. The transaction regarding the repairs of second hand machinery was recorded, just incorrectly classified.
• Error of Commission: This includes errors like wrong totalling, wrong casting, wrong balancing, posting to the wrong side, or posting the wrong amount. While there is a wrong posting involved (to the Repairs Account), the root cause is the misapplication of the principle distinguishing capital and revenue expenditure, which is the definition of an Error of Principle.

In summary, incorrectly treating a capital expenditure like repairs on second hand machinery as a revenue expenditure by debiting the repairs account is a classic case of an Error of Principle because it violates the principle of capitalizing costs incurred to bring an asset into use.
