The number of corporate bankruptcies last month rose 10 percent from a year earlier to 1,683, setting a new record for the month of November in the postwar period, a credit-research agency said Friday.

The figure, the fifth worst for any month since the end of World War II, showed bankruptcies increasing year-on-year for the third straight month and staying above the 1,800 level for the second straight month, Teikoku Databank Ltd. said.

November bankruptcies, however, were down 3.1 percent from the previous month.
