The Illinois Department of Financial and Professional Regulation said Friday it was giving American Home Mortgage Servicing Inc. until Oct. 22 to provide it with details on its foreclosures procedures.

The firm was one of four mortgage servicing companies that had not complied with a state request to provide information on its processes. As a result, the state announced earlier this week that it had told the four companies to show why they shouldn’t be barred from processing mortgage foreclosures in Illinois.

The state said Friday that its initial letter requesting the data from American Home Mortgage was sent to the wrong address.
