Nintendo has released its financial report for the first quarter of the fiscal year (the period of time from April 1st through June 30th, 2015), and it was a profitable quarter. Nintendo has experienced some financial hardships in recent years, but they're back to turning a profit, and they still have plenty in the bank.
The latest update on their finances puts their "Cash and Deposits" at ¥535,222 million. When exchanged for US currency, that puts their bank account at around $4,317,700,100. Nintendo's total current assets are at ¥1,048,266 million, which converts to $8,457,179,469. These numbers are all slightly down from three months ago, but when you look at total assets (including non-current assets), Nintendo's value has improved slightly from ¥1,352,944 million to ¥1,361,881 million in the past three months.
