The Royal Bank of Scotland has been mandated to lead a credit backing equity sponsor American Securities Capital Partners and company management in the buyout of Oreck Corporation. A banker familiar with the deal said the full details of the credit have not been determined. But he noted the deal is estimated to comprise approximately $140 million of funded financing with a revolver. RBS is out to possible co-leads on the deal, he added, noting that a retail launch will soon follow. The vacuum cleaner company deal is expected to be leveraged just over three times debt-to-EBITDA, all senior. New Orleans-based Oreck sells cleaning equipment and machines throughout North America, South America, Europe and Asia. A RBS official declined to comment. David Horring, managing director at American Securities, did not return calls. An Oreck official could not be reached by press time.
