, book value
or carrying value
is the value of an asset or according to its balance sheet
account balance. For assets, the value is based on the original cost of the asset less any depreciation, amortization or impairment costs made against the asset. A company's book value is its total assets minus intangible assets and liabilities. In the United Kingdom, the term net asset value
may refer to the book value of a company.
Asset book value
An asset's initial book value is its actual cash value or its acquisition cost. Cash assets are recorded or "booked" at actual cash value. Assets such as buildings, land and equipment are valued based on their acquisition cost, which includes the actual cash cost of the asset plus certain costs tied to the purchase of the asset, such as broker fees. Not all purchased items are recorded as assets; incidental supplies are recorded as expenses. Some assets might be recorded as current expenses for tax purposes. An example of this is assets purchased and expensed under Section 179
of the US tax code.
Depreciable, amortizable and depletable assets
Monthly or annual depreciation
are used to reduce the book value of assets over time as they are "consumed" or used up in the process of obtaining revenue. These non-cash expenses are recorded in the accounting books after
a trial balance
is calculated to ensure that cash transactions have been recorded accurately. Depreciation is used to record the declining value of buildings and equipment over time. Land is not depreciated. Amortization is used to record the declining value of intangible assets such as patents
. Depletion is used to record the consumption of natural resources.
Depreciation, amortization and depletion are recorded as expenses against a contra account. Contra accounts are used in bookkeeping to record asset and liability valuation changes. "Accumulated depreciation" is a contra-asset account used to record asset depreciation.
Sample general journal entry for depreciation
- Depreciation expenses: building... debit = $150, under expenses in retained earnings
- Accumulated depreciation: building... credit = $150, under assets
The balance sheet valuation for an asset is the asset's cost basis minus accumulated depreciation. Similar bookkeeping transactions are used to record amortization and depletion.
Liability book value
"Discount on notes payable" is a contra-liability account which decreases the balance sheet valuation of the liability.
When a company sells (issues) bonds, this debt is a long-term liability on the company's balance sheet, recorded in the account Bonds Payable based on the contract amount. After the bonds are sold, the book value of Bonds Payable is increased or decreased to reflect the actual amount received in payment for the bonds. If the bonds sell for less than face value, the contra account Discount on Bonds Payable is debited for the difference between the amount of cash received and the face value of the bonds.
Net asset value
In the United Kingdom, the term net asset value
may refer book value.
A mutual fund is an entity which primarily owns "financial assets" or capital assets such as bonds, stocks and commercial paper. The net asset value of a mutual fund is the market value of assets owned by the fund minus the fund's liabilities. This is similar to shareholders' equity, except the asset valuation is market-based rather than based on acquisition cost. In financial news reporting, the reported net asset value of a mutual fund is the net asset value of a single share in the fund. In the mutual fund's accounting records, the financial assets are recorded at acquisition cost. When assets are sold, the fund records a capital gain or capital loss.
Financial assets include stock shares and bonds owned by an individual or company. These may be reported on the individual or company balance sheet at cost or at market value.
Corporate book value
A company or corporation's book value, as an asset held by a separate economic entity, is the company or corporation's shareholders' equity
, the acquisition cost of the shares, or the market value of the shares owned by the separate economic entity.
A corporation's book value is used in fundamental financial analysis to help determine whether the market value of corporate shares is above or below the book value of corporate shares. Neither market value nor book value is an unbiased estimate of a corporation's value. The corporation's bookkeeping or accounting records do not generally reflect the market value of assets and liabilities, and the market or trade value of the corporation's stock is subject to variations.
Stock pricing book value
To clearly distinguish the market price
of shares from the core ownership equity
or shareholders' equity
, the term 'book value' is often used since it focuses on the values that have been added and subtracted in the accounting books of a business (assets - liabilities). The term is also used to distinguish between the market price
of any asset and its accounting value which depends more on historical cost
. It may be used interchangeably with carrying value
. While it can be used to refer to the business' total equity
, it is most often used:
- as a 'per share' value': The balance sheet Equity value is divided by the number of shares outstanding at the date of the balance sheet (not the average o/s in the period).
- as a 'diluted per share value': The Equity is bumped up by the exercise price of the options, warrants or preferred shares. Then it is divided by the number of shares that has been increased by those added.
- Book value is used in the financial ratio price/book. It is a valuation metric that sets the floor for stock prices under a worst-case scenario. When a business is liquidated, the book value is what may be left over for the owners after all the debts are paid. Paying only a price/book = 1 means the investor will get all his investment back. Shares of capital intensive industries trade at lower price/book ratios because they generate lower earnings per dollar of assets. Business depending on human capital will generate higher earnings per dollar of assets, so will trade at higher price/book ratios.
- Book value per share can be used to generate a measure of comprehensive earnings, when the opening and closing values are reconciled. BookValuePerShare, beginning of year - Dividends + ShareIssuePremium + Comprehensive EPS = BookValuePerShare, end of year.
Changes are caused by
- The sale of shares/units by the business increases the total book value. Book/sh will increase if the additional shares are issued at a price higher than the pre-existing book/sh.
- The purchase of its own shares by the business will decrease total book value. Book/sh will decrease if more is paid for them than was received when originally issued (pre-existing book/sh).
- Dividends paid out will decrease book value and book/sh.
- Comprehensive earnings/losses will increase/decrease book value and book/sh. Comprehensive earnings, in this case, includes net income from the Income Statement, foreign exchange translation changes to Balance Sheet items, accounting changes applied retroactively, and the opportunity cost of options exercised.
New share issues and dilution
The issue of more shares does not necessarily decrease the value of the current owner. While it is correct that when the number of shares is doubled the EPS will be cut in half, it is too simple to be the full story. It all depends on how much was paid for the new shares and what return the new capital earns once invested. See the discussion at stock dilution
Net book value of long term assets
Book value is often used interchangeably with "net book value" or "carrying value", which is the original acquisition cost less accumulated depreciation
