U.S. corporate bankruptcy filings continue to increase during the coronavirus crisis as 18 new companies joined the list of 2020 bankruptcies in the last two weeks, according to an S&P Global Market Intelligence analysis.

There have been 610 bankruptcies this year through Dec. 13, exceeding the number of filings seen in any year since 2012. The 18 new filings match the number of bankruptcies reported during the prior two-week period, continuing a slowdown from earlier in the crisis.

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.

Companies that entered bankruptcy proceedings Nov. 30-Dec. 13 include Florida-based American Purchasing Services Inc., oil field services company Superior Energy Services Inc., boutique clothing chain Francesca's Holdings Corp. and coal companies White Stallion Energy LLC and Lighthouse Resources Inc.
