Tangible fixed assets are usually recorded in an assets ledger, where details of cost, revaluations, cumulative depreciation and net book value are maintained on an asset by asset basis. Summaries by groups of asset type are also usually available.
The new asset is on the asset side of the accounting equation and is debited to fixed assets. The other entry of the double entry is to either reduce the bank account (with an immediate payment) or create an accounts payable liability, in either case a credit entry.
As an example the enterprise buys a new computer for £1,000 initially on credit terms.
Depreciation of a asset usually starts when the asset is first brought into use by the enterprise. The impact of depreciation is to reduce the value of the asset; so the asset side of the accounting equation is credited with the depreciation amount and the profit (Owners Capital) is reduced by the same amount, or debited. So for example if depreciation in the first period is £250, then (assuming the supplier has still not been paid) the equations would be:
An asset ledger should usually provide the necessary features to
The importance of valuation
The net book value of fixed assets shown on the balance sheet of a business indicates to readers that if necessary the assets could be converted into cash (by selling them) at approximately at that value. Where the owners of the business are aware that that value is really not correct, either too low or high, then the assets should be revalued. The amount of the correction accrues to the owners by either reducing or increasing their interest in the retained profits of the business.
Where the balance sheet is used to support a loan application from a bank or other lender, then the values of fixed assets would form part of the lenders due diligence process and it would be better for the figures to appropriate rather then the potential lender discovering a discrepancy.
