No. Few companies are worth their exact book value. Accounting a balance sheet in of itself does little to tell you the true value of the company. For example, Google's book value is roughly 100B while its market cap (the implied value of the company) is 360B. Why the discrepancy? Accounting rules are strict on how assets are valued and don't (nor are they meant) to represent the future cashflow that can be derived from them. Future growth, intellectual property and brands are basically not included in the book value. When a company gets acquired, this difference is made up through goodwill. This is simply a representation that book value is not a good measure of true value.
