Meadowbrook Insurance Group Inc., the insurer whose rating was cut by A.M. Best Co. last week, delayed filing a quarterly report to the U.S. Securities and Exchange Commission as the company reviews the size of a goodwill impairment it will take tied to the downgrade.

“In light of the timing of the downgrade, and the complexity of the analysis, the company has not had sufficient time to complete its evaluation,” Southfield, Michigan-based Meadowbrook said in a filing Friday. The company said it expects to file its quarterly report by Aug. 14.
