Business Combinations [Abstract] |
Business Combination Disclosure [Text Block] | 2. Acquisition Offshore Marine Transportation Business In August 2013, we completed the acquisition of substantially all of the assets of the downstream transportation business of Hornbeck Offshore Services, Inc. for $230.9 million, which we refer to as our offshore marine transportation business and assets. The total acquisition cost has been allocated to fixed assets based on estimated preliminary fair values. Such preliminary fair values were developed by management. We do not expect any material adjustments to these preliminary purchase price allocations as a result of the final valuation. The acquired business was primarily comprised of nine barges and nine tug boats which transport crude oil and refined petroleum products, principally serving refineries and storage terminals along the Gulf Coast, Eastern Seaboard, Great Lakes and Caribbean. That acquisition complements and further integrates our existing operations, including our Genesis Marine inland barge business (comprised of 50 barges and 23 push/tow boats), our crude oil and heavy refined products storage and blending terminals as well as our crude oil pipeline systems. That acquisition was funded with proceeds from our $1 billion revolving credit facility. We have reflected the financial results of the acquired business in our supply and logistics segment from the date of the acquisition. The following table presents selected unaudited financial information of our offshore marine transportation business included in our Unaudited Consolidated Statement of Operations for the periods presented:
| Three Months Ended September 30, 2013 |  | Nine Months Ended September 30, 2013
Revenues | $ | 8,651 |  |  | $ | 8,651 |
Net Income | $ | 2,520 |  |  | $ | 2,520 |
The table below presents selected unaudited pro forma financial information incorporating the historical results of our offshore marine transportation business. The pro forma financial information below has been prepared as if the acquisition had been completed on January 1, 2012 and is based upon assumptions deemed appropriate by us and may not be indicative of actual results. Depreciation expense for the fixed assets acquired is calculated on a straight-line basis over an estimated useful life of approximately 25 years.
