### What Is an Asset Base?

An asset base refers to the underlying assets that give value to a company, investment, or loan. The asset base is not fixed -- It will appreciate or depreciate according to market forces, or increase and decrease as a company sells or acquires new assets.

Although it is completely normal for a company to make changes to its asset base periodically by buying and selling assets, large swings in asset base will affect the company's valuation and can be a red flag for analysts. Lenders use physical assets as a guarantee that at least a portion of money lent can be recouped through the sale of the backed asset in the case that the loan itself cannot be repaid.

### Understanding Asset Base

A company's asset base is included in its valuation, and includes tangible, hard assets such as property, plant, equipment and inventory. It also includes financial assets such as cash, cash equivalents, and securities. Typically a company's market value will exceed its asset base since market value also includes intangibles as well as expected future growth from cash flows and profits.

With an investment in a futures contract, as an example, the price of the underlying asset used as the asset base of such a derivative contract can increase or decrease rapidly, changing the price that investors are willing to pay for it.

With a loan, the value of a home might increase or decrease over time, affecting the underlying collateral in a mortgage. Margin loans are particularly sensitive the underlying value of the collateral, as pledged securities whose value fluctuate with the market are often used for this purpose.

### Key Takeaways

• An asset base is the underlying value of assets that constitute the basis for the valuation of a firm, loan, or derivative security.
• For a firm, the asset base is its book value. For a loan it is the collateral backing the loan. For a derivative it is the underlying asset.
• Often, the market value of something backed by assets will exceed the implied value of the asset base.

### Book Value

A company's asset base is often construed of as its book value. The book value of a company literally means the value of a business according to its books (accounts) that is reflected through its financial statements. Theoretically, book value represents the total amount a company is worth if all its assets are sold and all the liabilities are paid back. This is the amount that the company’s creditors and investors can expect to receive if the company is liquidated.

Mathematically, book value is calculated as the difference between a company's total assets and total liabilities.

﻿$\text{Book value of a company} = \text{Total assets} - \text{Total liabilities}$﻿

For example, if Company XYZ has total assets of $100 million and total liabilities of$80 million, the book value of the company is $20 million. In a broad sense, this means that if the company sold off its assets and paid down its liabilities, the equity value or net worth of the business would be$20 million.

Total assets include all kinds of assets, such as cash and short term investments, total accounts receivableinventories, net property, plant and equipment (PP&E), investments and advances, intangible assets like goodwill, and tangible assets. Total liabilities include items like short and long term debt obligations, accounts payable, and deferred taxes.
