Bankruptcy Filings up 30% this year

This article is about the rather large bankruptcy percentage increase in the United States. It explains that the number of company bankruptcies, as well as individual ones, have both risen. However, the article goes on to explain that the bankruptcy rates are actually lower than that of two years ago. This is rather surprising to me. Why weren't people worried about this two years ago when it happened... Most likely the recession is the simple answer, but any ideas?
