Capital maintenance is an accounting concept, stating that a profit should not be recognized unless a business has at least maintained the amount of its net assets during an accounting period.
This concept excludes the following cash inflows and outflows that impact net assets:
- Increase in assets from the sale of stock to shareholders (increases cash)
- Decrease in assets from the payment of dividends or other distributions to shareholders (decreases cash)
The capital maintenance concept can be skewed by inflation, since inflationary pressure will inevitably increase net assets, even if the underlying amount of assets has not changed. Thus, it is more accurate to adjust net assets for the effects of inflation in order to see if capital maintenance has occurred. This issue is especially important if a business operates in a hyperinflationary environment.
Technically, the capital maintenance concept means that the amount of net assets should be reviewed for changes before determining the profit generated during an accounting period. From a practical perspective, this is rarely done - controllers simply calculate the amount of profit and do not review for capital maintenance at all.
The capital maintenance concept is concerned with the net change in account balances during an accounting period; it is not concerned with the proper maintenance of the capital equipment owned or operated by a business.
