This shows the accounting value of the assets that the business has purchased and expects to keep in the business for more than one year.
The most important component of non-current assets is "Property, Plant & Equipment" which refers to the business' fixed assets such as buildings, land, vehicles, IT equipment and machinery.
Items like these are treated in the financial statements as "capital expenditure" rather than "revenue expenditure". That means that, when a business buys a fixed asset, the amount paid is treated as an asset in balance sheet rather than as a cost in the income statement.
The accounting value ("net book value") of fixed assets comprises two parts:
Depreciation is a tricky concept to understand and often confuses business students. It is a cost that is recognised in the income statement, but it does not involve a cash flow! How does this happen?
Let's look at a simple example.
A business buys some factory machinery for £100,000 and expects the machinery to last for 10 years before it will be replaced. In the accounts, the original purchase amount of £100,000 would be treated as an increase in non-current assets in the balance sheet (not as a cost in the income statement). So the balance sheet value of Property, Plant & Equipment would rise by £100,000, offset by a reduction in cash of £100,000.
There is no change in net assets – all that has happened is that £100,000 of cash has been replaced by £100,000 of new machinery. The machinery is set to work for the long-term in the business.
Over time, however, the business knows that the machinery will need to be replaced; it is sensible to make an allowance in the financial statements for the reduced value of that machinery. That is where depreciation comes in.
Depreciation is an estimate of the fall in value of a fixed asset over time
There are various ways of calculating depreciation, but one of the most common is to simply reduce the original purchase cost of the fixed asset in line with its expected useful life.
In our simple example, the machinery was bought for £100,000 and is expected to last ten years. So each year, the asset value of the machinery is reduced by £10,000 (£100,000 spread over 10 years) – that becomes the depreciation cost in the income statement each year for that asset.
The total depreciation cost in the income statement each year is the total depreciation allowances for all the fixed assets that are shown in the balance sheet.
