Communication can be costly because how well you communicate will largely dictate your success, but I didn’t know a communication mistake could cost a business $340,000,000 (340 million)!
That’s what happened when a Japanese trader accidentally sold 610,000 shares of a stock for 1 yen instead of trading 1 share for 610,000 yen. Yikes! Talk about bad days at work.
A recent switched.com post (5 Typos That Broke the Bank) makes reference to this error, along with a $40,000 missing “l” and a typo that sends a woman 1,500 miles away from her intended destination.
Boy, I hate when that happens.

Paul, How about the all too common confusion of million versus billion. You fell into that trap in writing about the Japanese trader’s mistake. If things can go wrong, they will.
You should see the way I balance the check book.
