BETHESDA, Md., April 2, 2014 /PRNewswire/ -- American Capital, Ltd. (Nasdaq: ACAS) ("American Capital") announced today that it has sold its interest in ADF Holdings, Inc., the parent company of Anchor Drilling Fluids USA, Inc. (collectively, "Anchor" or the "Company"), to Calumet Specialty Products Partners, L.P. (Nasdaq: CLMT), a leading independent producer of specialty hydrocarbon and fuel products. American Capital received $33 million in debt and equity proceeds from the transaction, subject to post-closing adjustments.

The Company is headquartered in Tulsa, OK and operates manufacturing, mixing, storage and distribution facilities in Oklahoma, Arkansas, Colorado, Louisiana, New Mexico, Montana, New York, North Dakota, Ohio, Pennsylvania, Texas, Utah and Wyoming.
