What is the classification of opening inventory in the statement of profit or loss?

Opening inventory is classified as an expense in the statement of profit or loss because it is part of the cost of sales, directly affecting the determination of gross profit. When inventory is sold during the accounting period, its cost is recognized as an expense in the income statement. This relationship illustrates how the cost of inventory reduces the overall profit, as it is subtracted from revenue to determine gross profit.

While the opening inventory does represent an asset on the balance sheet at the start of the accounting period, it is not classified as an expense until it is sold. Its role in the profit or loss statement reflects the costs associated with generating revenue, hence the correct classification as an expense. This distinction is crucial for understanding how financial statements are prepared and how various accounts interact in the flow of financial reporting.
