Also Wednesday, Luby's reported it has reduced its unsecured credit facility to $30 million but made other changes to increase the company's financial flexibility. The amended agreement lowers the size of the facility from $50 million, but retains a $100 million accordion feature. Luby's said the amendment allows for increased capital expenditures.
