The number of corporate bankruptcies in the U.S. rose by 18 in the last two weeks, pushing the year-to-date total to a 9-year high amid the coronavirus crisis, according to an S&P Global Market Intelligence analysis.

As of Nov. 29, the year-to-date total outpaced the 579 filings in all of 2019 and exceeded the number of filings in any year since 2012. November, however, has recorded the lowest number of bankruptcies this year so far with 39 filings.

Market Intelligence's analysis is limited to public companies or private companies with public debt where either assets or liabilities at the time of the bankruptcy filing are at least $2 million. Private companies without public debt must report at least $10 million in either assets or liabilities at the time of filing.
