Above is a URL to Nintendo's 2012 annual report. Let me keep it simple for you. Maybe you should go back to the "school of humility" because on page 23 you'll see CLEARLY that Nintendo has over $2.1 billion in liabilities. I find your comments charming that you think ANY company on earth exists without having liabilities. It's fairly clear you aren't educated in business. Every company balance sheet has liabilities as it is part of what makes a "balance" sheet balance: as assets = liabilities + Shareholder's Equity. My previous comments simply said that if the debts were held in a foreign currency, it makes it harder for Nintendo to pay these debts if the yen weakens.
However, your statement about Nintendo being "undervalued" isn't completely wrong. As of today FYE 2012, Nintendo has a book value, as of around $15 billion. (annual report page 22) and the market value is just of $14 billion. However, all this means is that investor sentiment is poor because the business world thinks Nintendo will, in the future, be worth $1 billion less than its actual physical asset book value. I'd caution against using words like "Greatly" as they are far too vague for business language. What exactly does "greatly" mean?
Btw, Nintendo is down 2% in early trading today. http://finance.yahoo.com/q?s=NTDOY&ql=0
