Fixed Assets represent those assets and investments owned and used by the business for the long term to further the business. Fixed assets consist of three major categories.
For smaller enterprises it is only tangible fixed assets that will normally be relevant.
Tangible assets have been purchased to be used in the business with a view to generating income. It is clear that most tangible assets do not last for ever (except perhaps land) and therefore must fall in value over time, the recognition of this fall in value is known as depreciation and because of the double entry system it has two impacts. The first is to deduct an expense from income and the second is to reduce the value of the tangible asset.
In balance sheet terms, fixed assets are reduced in value by depreciation and at the same time the Capital is reduced because the retained profits are lessened by the same amount.
The trick is to determine how depreciation is calculated. The main factors that cause fixed assets to devalue are:
These factors can give some guidance as to an appropriate time period for calculating depreciation, for example an estimate of the time for a vehicle or computer to be replaced is relatively well known. Experience of other pieces of equipment will start to provide a guidance as to its life span. Clearly for something like a lease, the time period is known and the rate of depletion of an asset can be assessed. Rates of obsolescence are more difficult and judgement will be necessary.
In essence a time period for each asset (or more normally groups of similar assets) needs to be determined from the above. Having got the time period, for example five years, a decision is needed as to whether at the end of the time period the asset is totally valueless or if some residual resale value will exist. If a vehicle is assumed to have a four year depreciation life it may still be worth 10% of its original value.
We now have a time period and the total decline in value that must be depreciated (original value less residual value) a rule is now needed to determine how much depreciation is treated as an expense during each business trading period. Many rules exist but the two most common are
The straight-line method is very simple, take the amount to be devalued and divide by the time period and apply that amount to each trading period.
For example a Van costs £15,000, it is assessed to have a useful life of 4 years after which it will be worth £3,000. The straight line depreciation will be (15,000-3,000)/4 = £3,000 per year.
Reducing balance takes the cost amount and uses a percentage for each trading period. The percentage is selected to reduce the value of the asset to the residual value at the end of its useful life. So for example if the van above has a life of four years, apply a percentage of 33%. So in year one the depreciation is 15,000*0.33 = £4,950, but in the second year it is (15,000-4,950)*0.33 = £3,317 and so on. In order to determine the percentage that will calculate depreciation down to the residual value the following formula can be used.
Some useful terms
Sometimes assets such as Land and Building actually increase in market value and this needs to be recorded, this is done by revaluing the Cost Value of the asset to the new value.
