For clarity, capitalisation is what the company is worth, ie. the value of all the shares added together at today's market value. This is not really directly related to the assets, since the value of assets means very little until you take into account liabilities, and maybe goodwill as well. Further, what a company is worth may not be the same as what someone is willing to pay to buy it - many buyers will pay a premium to book value because they think its future revenues are worth the upfront additional investment. But - to return to the key point - there is a huge difference between a company's assets and its capitalisation/what it is "worth".
