Interesting analysis. There is another analysis from Quartz: 0 for phone business, 1.2 billion for BBM and enterprise infrastructure, 2.8b cash, 1b for patent portfolio.
I'd like to caution that this analysis is incredibly flawed. Specifically it magically ignores the entire liabilities side of the balance sheet (when you buy a company you don't just inherit their cash balances but also their debts). This is the problem with most financial journalism; you shouldn't taking financial advice from someone who doesn't understand the income statement or balance sheet.
All I did was take the balance sheet and pull out intangible assets: https://www.google.com/finance?q=NASDAQ%3ABBRY&fstype=ii&ei=.... I did NOT consider the value of earnings from any of the business (i.e. income sheet) as the investment thesis I made was for shutting down the business, and I don't want to divine profitability from each of the business lines.
They really need to require finance coursework in college so this kind of fake financial journalism gets stamped out.
