Market capitalization is the value of all the public shares, and is determined by investor sentiment about the medium/long-term prospects of the company as much as any other factor. The underlying assets are wholly owned by the company and have an intrinsic value that is easier to measure through accounting, but that alone doesn't take in to account the liabilities or debts on the books.
